Three month after Robin found his cure, it was summer vacation. The following school year, they all would be in 9th grade and would also have their trainee license test.

At this moment, Robin, Lola and Shoji went to Milo’s house and found him in the basement. The place had changed from pure glass cages to half cages and vases filled with ground bones from failed experiments. In each one they saw different breeds of plants but one thing was similar as the stem was white like bone and they released a faint glow over the flower.

“Hey Milo.” Robin said, walking downstairs.

“Hey.” he said simply, as he was working with some kind of powder before putting it in a small bowl with some water and then went to measure another powder and add it before carefully mixing and then put it in a small oven that his family purchased for him.

“What is that?” Lola asked.

“One of the five formulas I got. You can’t imagine how annoying it was to get them. It seems undead nobles don’t want the recipe getting out without bleeding those who want to buy it.” He said.

“What formula?” He asked.

“That specific one is Bone Supplement. After it finishes baking, it is up to me to either put it in a capsule or compress it into a pill. I already have a pill presser with the exact size for the package.” He said.

“Okay but how will we test it?” Shoji asked.

“Well I want to see the changes in a skeleton first. Also, weren’t you guys going to test the Life Force oil at the institute? We could see with some of the doctors if any bone deficiency patients aren’t willing to test it. If they don’t want my homemade ones we can take the required materials and they could make it themselves.” Milo said.

“That sounds pretty good.” Robin said.

Everyone agreed to the setup.

They waited until the mixture was cooked and basically baked dry before it crushed it again and put the powder over a small tray and made sure they were filled.

This isn’t 21st century stuff, a small energy field formed and pressed down into the powder. He filled it again two more times and took them out before weighing each pill and nodded.

“Good 15 grams exactly.” He said and turned around before snapping and summoning a completely new skeleton with it’s brittle bones. The link was easily formed and was even easier for Milo than the animal skeletons in the cages.

He took one pill and had the skeleton absorb the medicine.

They watched as the pill began to glow and turn to powder as it was absorbed directly into the teeth where the skeleton had placed the pill.

It should be mentioned that the skeleton wasn’t pure white like Bargo. It was yellow and rotting.

Everyone watched in shock as the yellow, starting from the teeth, began to turn white as it spread almost like a wave. First it covered the skull and then went down the spine and spread to each of the bones it passed, all the way down into the feet.

When it finished, broken sections began to regrow and mend while the bones began to thicken and get stronger until it grew from 160 cm tall to 180 before the effects finally stopped to change.

“Woah.” Milo said as he pointed and shot his undead biology.

They were shocked when a huge orb of spiritual energies came from it.

“Amazing… the bones were about as old and strong as an elderly person with a 5 year old’s strength like all base skeletons. Now the bones are amazing. They are completely brand new and are as strong as common athletes without powers. There is also not a speck of rot on the entire skeleton.” he said.

“Seriously. We just saw it physically turn from yellow to white. What the hell kind of medicine is that?” Shoji said, the most shocked.

“Milo, are you sure this is the proper dosage that actual people can take?” he said.

Milo also doubted and went to his desk and took out a leather book with paper made from some kind of strange paper.

“15 grams, the usage amount for base skeleton, skeleton warriors and barely usable by death knights. Weak living mortals should only use this kind to start with.” He read the passage.

Everyone looked at one another and understood what it meant. The skeleton was a clear representation of a weak skeleton becoming the required amount for useful skeletons.

“Hey, how many of those can you command?” Shoji asked, pointing to the skeleton.

“You mean if I just had base skeletons use the medicine?” Milo asked.

Shoji just nodded because he knew this was an important question.

“Hmm, it is still a weak one compared to the others, but it’s soul is still growing. I can’t exactly tell you at this time because of that.” he said.

“Keep a watch on this then, if it isn’t that much harder then the common weak minded skeletons you use, then these would be very helpful during rescue missions over base skeletons who are too brittle.” he said.

“Yeah.” Milo said but grinned, “I can’t wait to use this on Bargo and Scar.

Scar is Milo’s dear Zombie dragon which he perfected the basic form through using a lizard corpse with bat wings. The size was about as big as a car at the moment and it is pretty strong but it’s wings and muscles are still pretty weak.

“Do you think Scar will fly with this?” Lola asked.

“Bones are the foundation of the body while muscles hold a lot of power. Even so, undead don’t follow all rules of the living after all.” He said.

That was very true, the fact that skeletons exist and moving shows that perfectly.

They didn’t do that experiment though because they had plans.

Taking the few creams that Yez had brought and had a reaction to Robin, as well as the needed plants and a copied recipe of the bone supplement, Milo asked his parents to call a driver to take them to the institute.

At the same time, Robin called and informed them of the visit and they actually wanted to test some things but wanted to talk with a doctor about it.

When they arrived, they were surprised that an elder gentleman was waiting for them and after they unpacked their samples and materials, he led them to an office.

“Greetings children, the nurses were saying you wanted to talk to one of the doctors. Since I was free I accepted since it was you children.” He said.

“Thank you for the time sir.” Shoji said and gave a small bow.

Over the last three years, they have frequented the institute on a regular basis. They learned about a number of abilities and, as surprising as it sounds, several cases were resolved due to a way they suggested to use the powers. It was very similar to Mr. Johns who got a full bill of health after merging all the fragments twice and making orbs that produced world power that could be picked up and identified.

“Yes sir, well it is like this. It is related to me actually.” Robin said.

“Oh?” the doctor said.

They began to recount the event from 3 months ago and the doctor was in awe and he asked in detail. Lola even summoned Lily and she gave a detailed account of Robin’s genetic defect.

“Honestly, it always confused me as to why I never regained the water from the transformation if it was consumed. After what she said, I realized that I leaked water instead of consuming it.” Robin said.

“Amazing. I can’t believe we haven’t heard of any account that this resource tapped into. Still, using body oil which contains life force is quite something and I can let you use it in small amounts to see results but children…” he turned serious, “The medicine from the undead plane, even if made for both undead and living, has to undergo testing.” He said.

“We did a test with the undead at home. The medicine I made is a viable pill but we knew you might not agree so we brought a few for testing as well as materials to make it.” Milo said.

“Thank you for understanding. We really can’t account for it if we used untested medicine on patients and they died or suffered even more.” He said.

“Yeah, but both of these things might cause a lot of discomfort or pain since they clearly contain bioenergies or even supernatural energies that can affect the body.” Shoji said.

“Yes, I am aware but it is a scientific breakthrough to know that the genetics behind defective powers affects the life force. Maybe this very mild oil of yours can very well be a cure to many people suffering from problems related to their life force.” He said.

“It is our duty to help where we can sir.” Robin said.

“Alright, I will follow you children to a few patients to see if this life force oil works. There are a few cases of harsh skin problems alone.” he said.

On a hand console he began to pull up patient files and saved a few before getting up and going with the children.

The first person they visited was a rather shocking case. The ability of the person was unidentified but it caused his skin to constantly grow but never fall. They have had to surgically remove hundreds of layers of skin that threatened to block airways and joint movement.

Even Lily was shocked as she saw it and before they started, she asked for a blood sample through a small wound. Just like before she closed her eyes while letting them explain what was happening.

The person in question was a woman and she smiled, lifting many layers of skin around her face.

“Ah children, I didn't think I would get lucky to be visited.” She said. “So what is this little oil about?” She asked.

They explained about Robin’s cure. She congratulated him for finding his own solution. “So you will try that same thing for me?” She asked.

“Yes, we aren’t sure of the effects just yet but do tell us if you feel anything.” Lola said and summoned Yez.

The succubus was the only one who knew best how to spread the medicine and Lola asked her to pass it only over the right hand for the time being.

When the oil hit the skin though, the face of the woman instantly changed, “Woah, that is hot.” She said.

Everyone looked at one another and nodded.

Shoji moved and held her arm, “Please relax so that it doesn’t cause more pain.” He said.

“Alright.” She said and held herself from moving.

The succubus spread it only over her hand and they watched as her skin began to change and the oil was absorbed by the skin.

“Wow! It feels like I was injected with fire. Ouch!” She said she wanted to wave but the kids stopped her.

It took ten minutes to calm down and she sighed with relief, “Oh… oh now that feels nice. It suddenly turned icy cold.” She said.

That said, everyone was looking at her hand.

“Miss Keller, one moment.” The doctor said and she finally looked down and saw him hold her hand and to the utter shock of everyone present, he carefully moved her skin and it began to actually come off without pain as if it peeled off. It wasn’t a little bit either, a full 2 cm of skin came off from her hand.

“T-This.” She exclaimed and after her skin was removed she pulled her arm to see it herself. “My hand.” She said and closed and opened it. The thick skin wasn’t getting in the way anymore.

“This is a major improvement.” the doctor said.

At that moment, Lily came over. “Sorry to have to ask again, can I get a sample of blood from the healed hand.” She asked.

The doctor helped draw blood and she closed her eyes. After only 5 minutes she nodded. “Found it, after comparing her to the samples I have obtained many years ago of common humans. The problem here isn’t life force deficiency like the boy. It is improper distribution and a bit of genetic malformation.” She said.

“I get the malformation but what about the distribution?” The doctor asked.

“Her ‘power’ is supposed to be something akin to Rhino skin. It makes her skin thicker and harder. The problem is that this genetic trait is drawing too much energy from her body making it grow out of control.” Lily explained.

“What did the oil do then?” Lola asked.

“It fed her body.” Yez said.

“Huh?” everyone exclaimed.

“I explained that this oil helped my tribe abstain from 50% of our feeding requirement. The same happened to her, her body was starved for energy and when it got it, her ability was forced to fall into the proper path it should have. If the oil, for the kid, is a medicine that plugs the leak of his body's water, for her, it is a medicine that restores her body's energy flow, even if just momentarily. However, it has a huge effect as the countless layers of skin get removed and removes the danger of her ability.” Yez said.

Lola nodded but looked at the woman who was almost crying, “You shouldn’t cry so soon. The oil is a very good method to control your power, only control it. This is not like the boy who has life force deficiency. Your power is throwing the flow off and you will likely need to control it all your life.” She said.

“That is fine.” She said, already more than happy.

“Hey…” Lola said to Yez before she made a circle around her face.

Yez grinned and nodded. “Since we found something to help your problem, let’s remove this mask so that we can know who we spoke with.” She said.

Everyone was surprised but agreed. They had to hold her down initially but from her face to her scalp and even her neck, she had her head covered in the oil. It was definitely not the most pleasant thing but after it calmed down several nurses helped her remove all that skin and she went through another two applications until her natural skin was left and not the bulldog-like face she had.

Like newborn baby skin, her peach face was very beautiful after being unearthed and everyone took a picture with her and she had one of them take a picture of her and she sent it to her family.

Only half an hour later, her parents arrived and when they saw her, they cried out of joy that it was true and that she had a way to deal with it.

Yez took out a small jar for the family but said that they have to be very careful not to waste this because it took two month's to make a single batch. Even if she was having constant production now, it was still an exhausting process and the five demons had to get many imp tribes to cycle through to allow the workers some rest. It should be realized that demon world wood had to be heated much hotter than the atmosphere temperature so the heat coming from the wood is extreme.

They tested the oil on several cases of extreme skin problems and only partially helped them. Some of them had similar reactions and the skin peeled but it depended on the ability. One case wasn’t even skin based, it was someone born with dozens of horn-like protrusions and it was painful on her skin. Amazingly, the oil caused the protrusions to withdraw a lot into her body and healed the skin while removing a lot of pain.

They also tested the other creams and just found that women loved the smell and feeling. They weren’t medicine level body oil like the Life Force Oil.

When they returned to the office, the doctor got serious. “Children, I am sure you realize this but this is a massive business opportunity.” he said.

“We know sir. Next year, we will be going to high school and will be forming a heroes club. We will be selling lots of the common demon world creams as beauty products while the LF oil we used today we hope to make higher deals to help people who actually need it.” Lola said.

“We want your help to also test the medicine I make. Netherworld has many medical herbs that I have begun to rear under a small piece of land that my skeleton can take over and control common undead. Bone strengthening pills like the one I gave you are good for sick people with bone deficiency but it doesn’t mean that it can’t be used by common people. Imagine all the heroes who train daily. How many won’t grow up and might have some kind of bone fracture or other things. There might be many medicines that can help prevent future problems but most of all, bones are the structure of the body. If they can be made to grow stronger with careful doses, that will improve the strength of heroes everywhere.” He said.

That said, the doctor only grew more serious. “Or give incentive for villains to kidnap you.” he said. “Heroes have countless places to be and help, you children are only getting your trainee license. This is a dangerous prospect if they send even a vigilante level villain.” he said.

They were serious but they understood.

“Risk and reward run hand in hand.” Robin said with a smile. “For the time being, I don't see many people believing or wanting to obtain these kinds of medicine things. For our current situation, if we can have a government contract to provide these medicines or materials for them, that would be more than enough money for us to do all the things we need and then some for high school.” He said.

“That is true.” Lola said and smiled, “Not only this institute but many others can probably find hundreds or even thousands of deficiency cases that can be helped with a few medicines. It isn’t the common method heroes go to help people but it is definitely the least done.” she said.

The doctor smiled brightly at her words. “Yes, that is true, there are far too few people who look at these poor people. I doubt we can help them all but if we can help even one person in so many or reduce their suffering then we can consider it a save.” he said.

Everyone nodded in agreement.

They went to the car soon after and removed the materials Milo brought and gave a copied booklet with pictures and information on each of the provided herbs.

They bid the doctor farewell and went on their way. However, after getting the materials, his face turned serious and he quickly called some pharmaceuticals he was friends with. “Get here right now. I obtained a recipe that might be a major discovery for curing bone deficiency!” he said and explained what happened.

Soon the friend arrived and with the doctor, they followed the instructions and the information of the booklet to the letter and finally produced a 5 gram pill.

“How do we test it?” the pharmaceutical doctor asked.

“Let’s see the result on an animal of large size first, then we can use the drug on humans at a small dosage if it doesn’t cause problems. If it checks out, we go with a full 15 gram dosage on a serious bone degrading case.” he said.

“Agreed.” they nodded.

They brought an adult pig into a special room which constantly scanned X rays and they fed the pill.

They watched in the X rays as a shocking change happened in the pig and were shocked when the bones got bigger and stronger by a small bit but the most important part is that damage to the bones and even the teeth was gone.

After a few more tests and smaller animals, they finally took the reduced pill to an elder who had broken bones in his youth and had weakened from them and had to use wheelchairs.

They explained the test and the old man agreed. While in an X ray like always, this time they filmed it as the old man drank the pill and sat back

They were shocked as the old thinned bones strengthened. The old man needed to be restrained, however, but they grew shocked as his bones healed. Even the cracks left were closed and healed before they began to strengthen and grow. Almost like going back in time, the old man, with a hunched back and little strength left, actually lifted two grown men and his back straightened a bit.

When it subsided, the old man fainted from exhaustion.

When they checked, they found that he had anemia and a likely result of the bones consuming so much nutrition to regrow.

Both doctors were in shock and did a final test to a serious case of injured bones and bone disease patients but all of them were strong bodied and even some people injured in the line of heroic job who were unlucky to have injured their bones and were made to sit for a while.

In every case, they all were in great pain but at the end, the bones were restored and even diseases were eliminated and furthermore, if someone’s growth was affected as a result of bone problem, their bodies would definitely grow and develop. The strongmen that accepted the test, on the other hand didn’t have much strengthening but all the injuries their bones had, especially extremities where they punched and kicked, normally things that are super hard, were healed.

When the tests were done after not even three days, the Institute Doctor called for someone in the government who had any connection to the Institutes funding and went to show them the medicine so that they could have funds to obtain it. The doctor didn’t forget to bring the oil and show the amazing footage from the cameras in the rooms where the test had been done.

Each case was shown what had been done and how these things helped without causing more with far less pain to the patients.

“You said children, 13 and 14 year old children, came up with these things?” he said.

“It sounds ridiculous but this group has frequented our institute for the last 3 years and almost three fourths of all cases of cures through discovering how the ability actually worked is all on their part. Also I have spoken to both the summoned demon and the summoned undead of both parties who get the materials from those places. These things work, just this one pill that strengthened bones was able to heal a strongman. It is hard but they have more formulas and the materials to make it.” he said.

“So you want funds?” he said.

“Yes sir, it is basically funding the children’s heroics club as well as saving and helping hundreds of people who have been stuck without adequate funds to research. Even if this money goes to four kids, at least tens of thousands could be saved with the things they can make.” He said.

“They aren’t even trainee’s yet.” the government man said.

“But sir!” the doctor said.

“They aren’t… trainees yet.” the man said once more. “Let them set up their club. That way we can place their name officially on the discovery. It is one thing to be able to get the formula but we don’t know if we can make the materials that are from other planes.” he said.

“Thank you sir.” he said.

“Alright, you can go. I need to start work to obtain the needed funds.” he said.

“Alright sir.” the doctor said and took all his files.

After he left, the government man called the FBI and asked for information on the children and their powers before hanging up. “One source of materials is not a safe thing if we can’t bring them to earth.” he muttered before standing up and going to do his job.
