"Which one should I choose? Storage space or electrical heating?" After looking at the remaining survival points he had and realizing that he had enough points for either upgrade option, Su Mo had a clearer picture of his available options. 

"My current storage space is three cubic meters, and I have five cubic meters in Earth Tiger. If it weren't for my many treasure chests from before, I would've had enough space. Notwithstanding that, having a heating element is something I must have now, so I shouldn't need to even think about it!"

After trying to input some items that he had in the base into the upgrade panel, Su Mo made his decision and immediately spoke clearly and loudly when the number of survival points needed stopped reducing.

"I choose the third upgrade option!"

As soon as he said that, green light slowly overflowed from his body and turned into a pair of dexterous hands.

Almost instantly, the combat uniform, that had been originally neatly and carefully woven, was taken apart, forming green silk threads that were floating in the air.

The green light that had turned into a pair of hands began to circle around in the air.

It was as if the silk threads were like soldiers, moving in accordance with the orders of the hands.

"This looks magical! This upgrade feels far more realistic than making something out of thin air!"

The upgrade process this time was extremely slow.

As Su Mo sat at his workbench, he quietly watched as the combat uniform slowly formed under the weaving motions.

This new method of weaving completely toppled over the methods of textile weaving used during his time on Earth. It was as if a door to a whole new world had been opened for a modern human's learning capability.

"It's the perfect method of weaving textiles. By ensuring that every silk thread is weaved into the most suitable position, the entire thing, when combined, allows every silk thread to be interconnected with each other…"

"This kind of weaving method feels as if a soul has been given to the clothes!"

As the green hands shook, the silk thread on the collar shook and the silk thread at the very bottom also followed suit.

The combat uniform appeared to have become a living thing itself and no longer seemed like a boring inanimate object.

Su Mo watched the entire process until it came to an end. Even though the green hands were no longer shaking, the combat uniform was still moving by itself with no help from the wind, as if exuding its own joy.

After three to five seconds, the green hands retracted and the new all-terrain adaptable photometric combat uniform was completed!

The green light slowly retracted into Su Mo's body and the brand-new combat uniform floating in the air lost its source of power as it fell onto the workbench with a snap, making a light noise.

Immediately, Su Mo picked up the combat uniform and examined the surface material of the combat uniform curiously.

"There's no trace of the weaving at all. It looks like something formed naturally or, in other words, it almost seems as if it's grown out of the ground."

As Su Mo touched the neatly and carefully made combat uniform for the first time, Su Mo did not check its property panel immediately, but chose to instead pick it up and try it out.

The new combat uniform was not light in terms of its weight. After inspecting it, Su Mo found a palm-sized device on the waist area.

He pinched open the collar to take a look inside and it turned out to be a simple heating device.

The principle of the device was very simple. It had a built-in battery, a small fan, and an efficient and safe heating element.

After the power supply is turned on, the wearer would adjust the gear based on their needs. For example, when selecting the heating option on the gear, the heating element and the fan will be switched on, circulating warm air within the interior of the clothes and increasing the body temperature rapidly.

It was a type of technology that was inexpensive and commonly used on Earth. For example, the small sun heater used the same working principle.

It was just that no one was crazy enough to implement the technology into the inside of a piece of clothing. Su Mo did not know how the system adjusted the working mechanism to ensure that it was safe to use either.

"After putting it on, it feels about two kilograms heavier than before. The current combat uniform is about six and a half catties. It's not that heavy if I don't have my armor on!"

After putting it on, Su Mo smacked his lips and tried to make exaggerated movements for a while.

The new combat uniform was still the same as before. Not only did it not have any feeling of restraint, it also gave him peace of mind.

After he tried to move quickly a few more times, the temperature in the combat uniform rose rapidly.

He tightened up the collar and sat on the stone bench. It took more than ten minutes before Su Mo felt the clothes he was wearing slowly cool down.

"The heat retention is also very good. At least it's much better than my sweater. Besides that, the kind of warmth inside isn't the stuffy kind, as my body still feels very dry and comfortable!"

After taking off the combat uniform, Su Mo looked for a charging cable and connected it to the power strip before he started looking at the combat uniform's property panel.

[All-terrain photometric combat uniform (Excellent)]

[Description: An all-terrain combat uniform that can adapt to harsh low and high-temperature environments. Its excellent features include being moderately waterproof, moderately anti-viral, has slight protection from ultraviolet and infrared rays, as well as moderate wind and slight heat insulation. The new weaving method allows it to have some extra special abilities, which effects are more obvious in certain environments.]

[Special abilities: 

Photometric invisibility: From certain angles, its super material with negative refraction index, combined with the structure of transformation optics specially designed based on the material, can bend light and achieve the photometric invisibility effect.

Terrain adaptability: After encountering harsh terrain or weather, it will automatically adapt to a certain extent according to the current terrain and environment, and the corresponding characteristics of the clothes will also be slightly improved.]

[Comment: This time, you stand in a harsh environment and you're not sure if you should fear the King of Hell or the Jade Emperor!]

"Excellent quality!"

"The system upgraded it into an excellent-quality armor!"

As Su Mo looked at the excellent-quality label for the combat uniform, and the two special abilities it provided, he was surprised and shocked!

It seems that there's a big difference between good-quality and excellent-quality items. Having obtained such items from the ruins previously, Su Mo had developed a profound appreciation for those kinds of items since then.

There was a world of difference between excellent-quality and good-quality items.

A good-quality item meant that one of its properties were better than the rest. Usually, most people could see what their sole advantage was.

However, an excellent-quality item was different. An item with excellent-quality meant that there was an all-round improvement of the item. At first glance, there would not be just one point that seemed extraordinary, but rather, every part was equally good.

Even though he had spent 1800 survival points to upgrade the buggy into the Earth Tiger, it still did not break through the shackles of good-quality to excellent-quality.

Now, Su Mo only needed to spend 700 something points to upgrade an item to excellent-quality. This feeling was as if he had won a grand prize, and it lingered in his heart.

"It must be the magical weaving method that changed the quality of the combat uniform. It seems that there are still many things I don't know about item quality."

"I can't wait to find out what lies ahead. Perfect-quality, rare-quality, or even epic-quality equipment... All the way to legendary-quality. I wonder how powerful they'll be!"

When he thought about how powerful an excellent-quality item was and imagined the dozens of properties that might come with a legendary-quality equipment, Su Mo felt himself go dizzy.

When the time comes, having power of that caliber might make humans as powerful as the gods.

"I just need to continue working hard. With the current pace of my development, I know I'll reach that level someday!"

"When that time comes… Forget about the lion people in this world. I'll just break into their world and kill their horsesh*t Lion God and get all the blessings for my shelter!"

Su Mo chuckled to himself before putting away all the unrealistic fantasies in his heart, and began to sort out the things he had to take with him when going out later.

There were not many tasks for this day. In Su Mo's itinerary, he intended to park and hide Earth Tiger in the Deep-sea Shelter.

If there was nothing urgent, he was not going to go out.

As for dealing with the upcoming snowstorm disaster, it was basically not a problem for him after he obtained his air conditioner and heating pad.

However, the fewer survival points that were given by the system evaluation to him today reminded Su Mo of something.

"The system is changing and is urging me to not only survive, but to also live better and improve my quality of life. Only in that way would I be rewarded with more survival points."

"That's why... I really need to renovate my underground base or build some structures above-ground."

In order to increase his daily fixed rewards, Su Mo looked at the resources in his reserves and decided to think creatively. He knew he had to start upgrading some things.

While his equipment was charging, Su Mo returned to the living room and started his training. He trained using the good old training methods that his father taught him and ended up sweating all over. 

Not only were the simple military martial arts exercises effective against enemies, but the more precise the movements were, the greater their strengthening effect.

Su Mo alternated between some push-ups and jumping burpees. After slowing down the wind speed in the shelter, even after Su Mo's body heat dissipated, the shelter did not feel cold at all. Instead, there was a sense of comfort.

After a full hour of training, Su Mo stopped.

He sat on the stone bench and directly scooped up half a scoop of psychic energy water from the water tank and drank it down. His physical strength quickly recovered.

"Two days have passed and my strength hasn't changed significantly. It seems that it must be related to the ruins..."

Without a device to measure his strength, Su Mo could only use the most primitive method.

He judged his strength by the weight he could carry. When he tested his strength just now, Su Mo felt that he reached his limit at one hundred and eighty catties of iron blocks.

"The limit of the amount of weight I can lift is 90 kilograms, which is still a long way off from the strongmen and boxers on earth but, compared to the time before I came over, I've come a long way!"

After Su Mo touched the bulging muscles on his arms, he smiled in satisfaction before taking off his sweater and holding it in his hands.

The violent wind blew past noisily like a hair dryer. After less than a minute, the sweater was already fresh and nice when Su Mo put it back on.

The all-terrain combat uniform's battery being charged by the side did not look big, but the battery capacity was shocking. Even after three full hours of charging, it was still not yet fully charged.

The other electric equipment had already had their indicators flashing green.

After Su Mo looked at the color of the sky and judged the time, he did not wait any longer. He unplugged the equipment and began to put them on one by one, preparing to go out!
