The next morning, the rest of the students were all put to do many different exercises, what kind, well each and every one of them to force their abilities, however four of them were looking at Mr Might with stifled expressions in silence.

“Alright you all… you are the last ones.” He said.

They looked at him waiting but he didn't talk and instead had them follow and they went to a cleared space but waiting there was a small table with some ring like objects on it and he took them and tossed a pair to each of the boys.

“Put them on your arms.” He said.

“How?” Kevin asked.

He takes another one and shows them where the unlock button is and they each secure each to their arms and once they had it on he nodded.

“Good, these are expansive gravity weights, they can morph and expand to match even the largest giants no matter the size.” He said.

“Gravity…” Robin said just for the bracelets to light up and suddenly change as they went from rings into bracelets and instantly they felt the weight of gravity crash on them.

“Welcome boys, to the world of physical training for super strength heroes.” He said.

Kevin was already huffing and bent down from the doubled gravity acting on his body.

“What… Did you do?!” Marcus said.

“These are gravity bracelets, like I said. They work on technology that researches psychic abilities of the same kind and can mimic the effect. If you look at the underside you will find a psychic stone but unlike the kind to amplify psychic power, these are meant to activate a certain effect on the user and they work off world power, another technology researched extensively since world power is limitless as long as the world exists.” He said

“What… is the point.” Silk said, pulling his body upright.

“You all are going to train with this naturally, you are all among the strongest or the ones with greatest potential for psychical strength in your classes. For you, kong boy, your size and strength are directly proportionate however you have trouble training your strength so the way to do it is force your body to move skillfully with double your weight. Kevin, you will build strength naturally and quickly like this and catch up to these three and maybe surpass them even. As for you Silk, you have a rare talent for training your body and this builds off that talent.” he said.

“And me…” Robin asked.

“This is to train many things, first off your hardening, secondly your titan power control.” He said.

“Wait… don’t tell me…” Robin said.

“Yep, you are the moving target and you need to train remaining in your hardened state while also learning to move with your body clad in titan power. Like this, your body absorbs this new energy which is primarily stored in your dantian instead of your cells.” He said. “Also, from what I have read, the usage and constant reusage of LP oil has a positive effect on your deficiency which stems from your life force. As such, stimulating your hardening while supplying the ‘repair’ solution, will also improve your condition. At the same time, training you under heavy gravity will make your body grow stronger.” He said.

Marcus grinned as he looked at Robin, “A punching bag through and through.” He said.

“Don’t joke around, he can kill you with one punch at the moment.” Mr Might said. “Robin, you aren’t allowed to throw a single charged punch because you still haven’t figured out how to keep the energy from invading your punch target.” He said.

Robin was frowning, “How will I apply my LP oil.” he said.

“Oh right, your suit is over there.” he said pointing to a suitcase and the gravity on Robin instantly shut off and came off.

Robin sighed as the weight came off and he groaned as he put on the suit and he came back and warned the others where to avoid if they didn't want an explosion of liquid nitrogen.

He reluctantly put on the weights again but he was ready and his posture changed only a bit before he breathed deeply and started to adjust.

Like that they were released into the open space.

“I don’t think we need to wait for much.” Marcus said as he walked back.

His body began to grow but he was groaning because naturally his mass had increased but he started to feel the changes as each part of his body felt heavy and he needed to adapt.

“Don’t need time, my ass.” Robin said, rolling his eyes and walking a short distance and began to breathe calmly.

In the morning he woke up to find the atlas stone very energetic unlike before and Mr Atlas was much better. After his ‘being’ adapted to the new energy the rock began to saturate it from inside out. During the middle of the night it had finally balanced out and began to produce titan force in greater quantities. It had started thin but it quickly gained the same density as the one Robin contained.

When he woke up he absorbed that energy and it took a surprising 5 minutes for his body to be full while he had about 30% of his dantian full but it was more than enough and he returned to the state he had been before the change.

At this time he started to channel that power through his body and very soon the energy in his cells started to get agitated as it began to move with the flow and he took about a minute for his body to be clad.

Like the first time it was hard to move and he groaned to move even just a little bit as he was conscious of the pressure it was causing.

“Alright.” he said.

“You aren’t going to spring?” Kevin asked.

“I can’t.” Robin said as his suit applied his oil and he hardened. Surprisingly this drew in the flowing aura under his skin but it didn’t become any easier. That said, as the trait had explained, the energy was aiding the oil counter his deficiency and formed a barrier around his skin containing a lot of the fluids that were trying to leak in a double layer.

“Alright then, let’s have fun.” Marcus said and walked before swinging at Robin.

He could only react by instinctively crossing his arms and feeling the force of the giant ape smash his body like a truck and be sent flying and his concentration break.

“Work hard Robin, concentration!” Mr Might shouted.

Robin groaned as he took the energy that was trying to return to his body and he started to reform the clad but Marcus didn’t wait because that was what he was told and this time kicked Robin into some trees and had him leave a faint imprint.

“This feels so good.” He said.

Robin growled at him as his anger started to make him slip a little in concentration but Mr Might appeared and pulled him up from the ground, “Focus. This is an exercise to learn fine controls of this totally new power you never had. You need to learn to reduce the amount of power so that you can pull sufficient energy for what you want and not excess that makes it hard to move. You can’t move a flexed body part so just calm down and focus.” He said.

“Then tell that monkey to shut up.” He said.

Mr Might looked at Marcus after hearing that and growled before walking back to the center and Robin quietly followed and tried again but even when he tried he still pulled a lot of power but this time it was Kevin who came and began to fight with punches and kicks that he had been learning through boxing classes.

This was perfect as it wasn't hard enough to throw him but it was perfect to let him concentrate on moving.

Sadly there was one idiot that didn’t think that as he came with another kick that Robin jumped to dodge before feeling the power slip and he started pulling it again and filling the void and felt the unstable energy.

He groaned and finally began to move the power that was stored like the technique to compress it and all the wild power started to get pulled in and he was surprised that it released far less but by the time he noticed Silk jumped and brought down his head on his head breaking his focus before being lifted by him and thrown where Kevin punched him but that just stopped him where it happened.

Robin coughed because he lost all control and Mr Might had to stop it again.

“Sir, this isn’t going anywhere with him having to stop.” Marcus said.

“Yes, well unlike you, he has to focus on moving internal energy. Now be quiet.” he just said and helped Robin get up and Robin nodded and began to focus but this time the energy began to spin and only half of the previous amount of energy he was releasing was released and he was able to fill his body but the pressure wasn’t as much and he could move with a bit more ease and nodded and had the others start.

This time Marcus just came at him in human form since there was no point in wasting time and the three began to punch and kick him heavily. This time Robin didn’t break concentration from a random smash that would completely break the flow and his movements started to slowly catch up, despite that they spent nearly 2 hours under heavier gravity and it was a draining exercise on all of them and when Mr Might finally called it and the gravity bracelets deactivated they all collapsed.

Robin was the most affected and Mr Might brought a large amount of water which he sucked in unreservedly regaining his strength and sighed happily to remove the helmet while his suit was working hard to reduce the heat.

“Seems after unnecessary egos were put away you got to a good workout.” he said.

Marcus didn’t say much to that because even now he was feeling the burn and was sweating heavily.

“Good, take a short rest before we start again until lunch.” He said.

No one could say much but the three collapsed on the grass and just breathed deeply.

Robin wanted to do the same but he didn’t, he sat down and took deep breaths as he tried to focus on the flow of energy and he began to think of how to reduce the flow.

His first instinct was how he channeled his energy the first time but as he tried he found that it didn’t have much effect.

After a minute he took the spinning energy stored up and split it in two and produced an upper spinning flow which then channeled into a second spinning flow and this actually worked to reduce the amount of energy released was half of the second attempt but it produced a new problem, he couldn’t move at all because of the focus required to maintain the spin.

After that he tried spinning along the channels but that didn’t do much and he sighed as they got back to training.

When it was time for lunch, they trudged to the mess hall like many others. Robin got his food and seeing Mr Might with only the bravemen he thought and walked over, “Mr Might, can i sit and asked for some advice.”

“Sure, what do you need.” he said.

Robin sat down while the three bravemen were curious and were listening.

“Well…” he said and began to explain what he had tried during his training while trying to control the output and how it was either 100% or 50%.

“Oh, most people who unlock this later in life tend to face the same troubles. Honestly, it is basically a lack of proper training to allow the body to adapt to the energy.” Rain said.

“What is the most efficient way of training you have done?” Amber asked.

“Most efficient…” Robin said, “Involving the power, it was definitely when Mr Might told me to run while running with the rock. The power collapsed on me like a waterfall and constantly kept my body energized while constantly training but it was before I made titan force.” he said.

“Alright… then we have what we can work with.” Rain said.

“Yep, you just need to train while carrying the rock and it is likely that your body will adapt to the constant saturation and feeding it.” Harvey said.

“I see, then I will split your morning and afternoon training between gravity training and running with the rock.” he said.

Robin sighed and nodded but didn’t move and began to eat alongside them and listened to their talks which weren't about training but their analysis of different powers.

Half way through Robin actually butt in because he noticed some things after they talked about some students and their powers felt like they could do different things and he told them.

His view was actually very curious to the adults but he couldn’t make conclusions because he didn’t know much about the powers.

It was still interesting but by the end of lunch they had to get the students back into shape after a short rest for them to digest their food.

Robin had to go to Mr Atlas.

“Did you need something?” Mr Atlas asked.

“Not really, I have to train.” Robin said.

He gripped the giant stone and it began to glow and the weight slowly vanished and he lifted it above his head and walked towards the training field before fixing his posture to receive the weight and it fell on him and he once more fixed his posture and fixed the effect so that it would help hold itself up while he ran and finally started to run with slow heavy steps.

The first step followed by the titan force pressuring him instantly and he instantly groaned but started to run while starting to flow his stored power to constantly train himself.

The pain grew but after a bit he was able to achieve a slow jog before he hardened while running and adapted a little more until he fell into a stride for the next two hours before he took a break and than continued this until 6 pm where he dropped it off and went to dinner almost dead from exhaustion despite the inexhaustible energy that was pumped through his body.

He felt sick, tired and literally shoveled everything that fell on his plate and had to get a lot more food, something he never had to do before. It actually reached a point where Mr Might had to stop him because his stomach was already forming a rounded gut.

He just went back to bed and without any arguing with the others, he just climbed into bed and instantly fell to sleep.

The others arrived an hour later and as they entered, he was surprised to find Robin’s stomach was normal and even growling and he was complaining from hunger.

“What the hell happened to him?” Silk asked.

“Could his training have begun to change his metabolism?” Kevin asked.

“Whatever, go call Mr Might, it is going to be a pain to hear his stomach growling all night long.” Marcus said to Kevin who did just that.

When the four teachers came to check, Mr Might channeled some True qi and nodded, “Yes, it seems his body did begin to change and it is consuming a shocking amount of energy.” He said.

“He is likely going to become like pro athletes where they finish an entire banquet table alone just to have the energy to exercise and burn it all.” Amber said.

Silk and Marcus frowned when they heard that. “Is this normal?” Silk asked.

“For people who develop a potent internal energy it actually is quite normal. All four of us went through it at one point. Probably several times in fact when our energy density reaches a level that our bodies need to adapt causing us to require a huge amount of nutrition to support. Besides, world power not being his natural energy, he even made it into a compressed force so his body is definitely undergoing a lot of changes, especially his life force which is heating up in his blood likely being affected from the minor lack of food. If fed properly it will grow.” Mr Might said and had the others bring any leftover food they could and in the greatest quantities they could.

After about half an hour there was basically a large table of cooled food and Robin was half asleep when he was put down.

Mr Might held him down and with a very thin coat of true qi, he gave Robin a firm slap in the face that instantly woke his senses.

“Huh?!” he exclaimed, holding his face and looked around before his stomach rumbled like the growl of a beast. “What happened, huh?” he said and finally noticed the table and instantly began to drool.

“Go on and eat your fill.” Mr Might said.

That was all he heard before he actually began to shovel down with a lot more energy and they watched the comic sight of what happened when a person with a rubber body ate ‘their fill’ while having the metabolism for that.

When he finished cleaning off the table and finally satisfied he was round like the giant boulder and fell backwards on his back already sleeping not caring where he was.

“It’s like watching a cliche anime protagonist, the glutton kind.” Marcus said.

“It does feel like that doesn’t it.” Silk replied. “How does a human body even process that much food?”

“You would be amazed what the human body can do. The fact that we can change our sizes like the kong boy without breaking our bodies from the expansion and compression of our mass and the mystery behind where all that mass goes, is but one of the countless things. A person with a strong internal energy suddenly activating abnormally fast metabolism is pretty basic on this scale. Most super strength heroes have gone through this and some live with this condition even.” Rain said.

“Are we going to be like that?” Kevin asked.

“Silk and Marcus likely but for different reasons, Silk is training chi and is likely to feel this when he finally produces True Qi but Marcus is likely to feel it when his body finally reaches a growth spurt when his muscle training finally bares results and he will need the food to grow that mass.” Amber said.

“For now, you kids just go rest, training won’t get any easier even if you beg so get lots of sleep.” he said.

They groaned and decided to go since there wasn’t much internet here to do much else anyways.

Mr Might dismissed the teachers and laid down against the wall and just stayed there to make sure Robin was safe but he still marveled at the round ball that was Robin’s belly as it slowly but visibly shrank as time went on. It was a unique view that could barely be seen by normal people. Even when he was going through those phases he still had a limit that was his stomach size. No matter how good his metabolism was to break things down, he still could only eat one tenth of what Robin ate at any one sitting because it wasn’t humanly possible to eat more.

However Robin could because his body didn’t actually have a stretch limit.

He actually began to think that the strength elastic class was quite powerful if it was supported by an additional internal energy like this. Sadly unless the energy is natural in an ability, it is difficult for most people to unlock any form of internal energy. Robin was basically the same until Mr Atlas turned into the rock and fed world power into Robin.

“This combo might have birthed an extremely powerful hero this time around.” he thought.

When Robin was back to normal size, he was already dead asleep and as deeply as before but he was quite calm.

Mr Might lifted him up and curiously found that he didn’t react like before and shook his head, “Well one thing doesn’t change, elastic heroes are all deep sleepers. Their lack of fear of blunt force even when everything is falling on them is unique to these guys.” he said and unlocked the door quietly and put Robin to bed where he quickly rolled around and found a good spot before he left for the night.

The following morning Robin woke up feeling very good and even laughed as he did morning stretches which cracked a lot of bones as he pulled joints in the most unnatural way that only his power type could to crack his back and limbs.

He spent only a short time to fill up because of the amount of energy constantly filling him the previous day so besides his body, the storage was 80% full and he didn’t let it get to 100 out of fear of what could happen.

Surprisingly, to those who had seen him, he was eating pretty normally with only a single normal tray of food and it even confused the hero who looked from afar.

“Did something happen? I’m pretty sure people tend to go nearly a week to satisfy themselves.” Harvey said.

“Yeah… but Robin can stuff it all in one sitting it seems.” Mr Might said.

All the students and teachers split up after breakfast and the four gathered up again and Mr Might asked Robin to give his fist a straight punch.

He did that and, to no surprise, it was pretty normal. In fact, it was extremely weak for strength types because a straight punch from him carried only roughly over 1000 kilos of raw force. Naturally that amount of weight was the same abnormal amount Robin could lift up as well so over 1000 kilo of punch force is not the same as 1000 newtons of force that most scientists calculate. His punch is like a one ton block falling on it’s edge against the target. All that power is concentrated into a small surface and that isn’t counting when he puts his body into it. This was raw force.

Taking the punch as naturally as a mountain getting hit by a pebble he smiled as he felt the force. “That is about 200 kilos higher meaning his strength might have raised about 20 points just from training with the rock one day and getting more adapted to it.” he thought without saying much else and they all put their equipment on and Robin started another hard day as a punching bag but everyone quickly noticed a change.

First was Robin’s max ‘aura’ which excluded like a flame around his body even in his hardened state before he reduced that to his 50% state which made it like the previous day where it just covered it like a glow but with concentration that kept dropping down until he was able to stability contain it to 40%.

His movements were like the previous day because the quantity matched his previous max but Marcus tested something as he went into his giant form and tried to kick Robin and he could dodge and when he swung a hammer fist on him Robin took it and they shockingly learned a new feature of titan force as it was forced into the ground making it collapse and cushion the force applied on Robin.

After that he shrank and they all began to punch at him from both sides and back and besides some dodging he could do for big swings he took quite a number of hits.

For the three, whether punching kicking or headbutting, the heat itself from Robin, even with the cooling system, was a test on it’s own and punching at hard rubber also started to bruise them just like punching stone or wood for long hours of training would and after two hours they all collapsed in exhaustion.

Robin was on the ground as well as he controlled his power which had dwindled by a shocking 20% that was consumed by his own body.

At that moment, while they were huffing in exhaustion, Robin was undergoing a very tiny but also major change out of his control.

With all the training, his life force was constantly growing and at this moment, because of the stimulus from the titan force, his life force was vibrant unlike what it normally should be but many genetic defects made it weaker than it should be but it had reached this point because of the food he ate and the purity of Titan force.

At this moment, the amount of life force reached a moment of critical mass forming tiny nodes, which stopped in the heart, slowly gathered before pushing against the heart barrier and leaked in one drop at a time.

Indeed, this was the natural formation of life essence. All living creatures can naturally form it through intense training but few people could use it like power users that use life force as the power source.

For Robin, this had very special meaning because as the life essence nodes finally gathered and completely blended into a proper drop it began to draw and release life force that began to improve in quality but reduce in quantity but at a very slow pace.

It produced a lot of heat that he thought was from the beating so he was more than happy to drink water to help cool down and replace his lost fluids.

When his body was back to peak the life force slowly moved and began to replace life force in all cells and that energy went back into circulation and the slow process began however he wouldn’t realize until much later on. But this wasn’t a fast process and would need month's.

For the time being, they turned back to training until lunch time before they each went to their own training and Robin returned to the stone to start training once more under the pressure of the world which had stimulated his body to reach the state it was reaching.
