A month and a half after the start of the school year, the military school became completely calm. The freshmen were busy practicing and getting acquainted with their freshman-like bodies, and their first assignment would not be until at least three months later, and the things in the school had little to do with them now. As for the second-year students, the rest of them have strong self-control and can completely suppress the restlessness in their hearts all the time. They will all gush out completely and unreservedly with this heart, beating violently at a certain moment.

Kasiya did not waste any time, as early as half a month ago, he collected the surgical development materials on the heat resistance of the arm part, and began to try to learn this ability.

The influence of external environmental factors and the inner spiritual will is mentioned in detail throughout the material. These are the two main directions of surgical development, and they are also the two most important.

In the military academy, there are basically no external factors, and they can only be created by themselves. After that, every day of training and theoretical study was ended a little earlier, and then he returned to the room early and began to "hone" his hands in all aspects.

The need for a blazing environment, more than a dozen documents have mentioned it. However, the environment of the school is just the opposite of what was said above, and there is no way for schools that are in a cold climate all year round to find a suitable heat source.

Therefore, it can only be replaced by hot water in the early stage. The boiling water in the cafeteria was a good ingredient for experimentation, so I went to the school shop and bought a larger kettle. After training and eating, returning to the cafeteria to turn on the water has become the norm in his life. The water temperature of about 100 degrees Celsius should still be within the range she can bear, and Kasia is confident.

After opening the cross pupils, and reaching into the water for the first time, Kasia herself still retains a strong instinctive resistance to herself. After all, it is something that you take the initiative to do, and the kind of danger consciousness that ordinary people still have is still at the bottom of the body.

As a result, I was burned on the first day. Kasia felt a sense of humorous and ridiculous in her heart, and she didn't know what to say about this behavior. It wasn't serious, and I went to the school's medical department to prescribe a few quantities of hot medicine. Combined with his strong self-healing ability, the injury completely improved within an hour or two.

At this time, the first layer of skin is peeled off. Kasia originally thought it was just dead skin burned by hot water, but under the light, through the vision after opening the cross pupils, she found that it was not the same as she thought. It should be said that it was not all dead skin, but the part of the arm that fell off on its own, and he could tell it.

"The progress seems to be different from what was described in those cases, and the feelings described are completely different. Kasia looked at her hands as she had peeled off a layer of skin, a little puzzled. The skin color has become darker. After returning from the base of the volcano, that fresh and fair skin was gradually returning to his original skin color.

"After that, the color will deepen again, and after a sepia peak, it basically means that the development is mostly complete. Kasia thought about the different development timelines, and he was still in the beginning of his current state. It's just that the speed of the case is not in line with the case. Generally, when the arm begins to shed a layer of skin, it is ten or so days after the arm has been burned with an external heat source. And at that time, what is removed is simply dead skin, and it is a simple and normal skin self-renewal.

I don't know if it's a good thing or a bad thing, but Kasia can only go on with her head stubborn. After a few days, the results have already begun to take effect. After those scald medicines are used up, the cross pupils are turned on, and the two arms will no longer be burned by boiling water. You still feel the burning pain during the soaking process, but it seems that you have developed some resistance. The water of 100 degrees Celsius could only burn his hands red.

Soon after, the arm began to undergo a second molt. It was far more uncomfortable than the first time, like a snake struggling in the grass, trying to scrape off its dead skin by external friction. For the first time, Kasia saw firsthand the dramatic process of skin shedding to regeneration.

It was what had happened after the soaking, and there was a slight numbness in her red arms, and Kasia lost the sensation of her hands for a moment, followed by the burning and twisting pain. The whole process took less than ten minutes, but every minute went by a long time.

The new skin is darker, and the wheat has a brown shadow in it. After that, the heat resistance changed significantly, and it became better, and the improvement was not indispensable. By the second time he simulated the external environment with boiling water, Kasia knew that the method had lost its effectiveness.

When Kasia was thinking about how to continue to simulate the external environment, he asked Derya to send the object for more than half a month before it finally reached his hands.

Wrapped in a rainproof cloth and a thick layer of tin foil, it is unusually tight. The tin foil is in the outermost layer, well protected, not damaged, and of course there is no trace of being opened and inspected by others.

Two pneumatic weapons with glow pipes were placed in their entirety, all of them long swords, the type of cold weapon that Kasia himself was most proficient in using right now. And the silver aluminum leather box he was talking about. When you open it, you can see several layers of shock-absorbing cotton lined inside. A whole set of those flat syringes that he had previously had Della custom make was on display. After being reminded by Dr. Dole, the concentrated dragon blood he had diluted with tranquilizers had already been packed in these syringes.

The moment he saw these syringes, Kasia's head suddenly went into a trance. I remembered myself who was almost mutated in the rearrangement, the black rough scales, and a tail covered with sharp barbs. At that time, the delivery team on the train was killed in a very short time. In the end, the whole head of the captain was weathered by the scorching air current, and it is still deeply remembered today.

"Is there a reason why the operation will progress faster than those data cases, and the nodes will be different?" Cassia felt that he had found the beginning of the problem, because he clearly remembered that when he was in a column of steam that was rearranged all over his body, the superheated steam in the center of the column did not show a trace of burns on him.

I feel that there must be a connection, but with Kasia's current understanding of surgical development, it is not yet possible to fully sort out the necessary connection between the two. Without much thought, he continued to simulate the external environment by relying on hot water, which was becoming less and less effective. There are also bold moves, and thanks to his sensitivity to steam machinery, Kasia successfully found the power transmission drawings inside the walls of his dormitory room in the library. Attempts have been made to pry open walls with tactical knives and release steam from copper pipes to obtain a constant and reliable source of heat. However, the steam transport pipeline in the military school was of good quality, and the plan was not realized. During the time when I couldn't go out of the military school, if I wanted to continue the development of this surgery, I could only rely on another general direction.

"Inner spiritual will?" thought as Kasia lay flat on the bed at night, rubbing his hands with increasingly rough skin.
