With the experience of cutting himself for the first time before, Gao Gao's hand holding the knife this time did not shake violently, and even a little calm.

It's just like the same mood he had when he slaughtered the pig, and it was not right, he was so scared that he was about to pee his pants, it should be very similar to his mood when he killed a chicken again, in one word, that is: not shocked.

With a fist in his left hand and a knife in his right hand, he slashed high at the area that remained before.

"Huh?"

The signal of the pain did not reach his cerebral cortex as expected, and there was no blood flowing out of his arm, and the blade was imprinted on the tight skin, and it was unable to enter the flesh for a long time.

"Is it because of the contraction of the muscles, which produces an effect similar to that of hard qigong?"

Gao Gao was a little puzzled, hard qigong can be explained by scientific knowledge.

In layman's terms, people who practice hard qigong have local reinforcement of their own cell population and muscle tissue due to long-term contact with anti-attack training.

On a microscopic level, people who practice hard qigong will have thicker cell walls than ordinary people, and the intercellular space will be smaller.

But there is a premise for this, and that is that they have to be prepared.

If these people are unprepared, they are no different from ordinary people.

To take the simplest example, when the muscles are tightened, a hard qigong practitioner can kick a small tree with a thick bowl mouth with a whip leg.

If he didn't tighten his muscles, whipping his legs against a small tree of the same thickness would most likely make him squat on the ground and hold his legs.

Thinking of this, Gao Gao let go of the clenched fist of his left hand, and sure enough, this time the knife was successfully pierced, and after a wound of about 2 centimeters, he stopped.

Unlike the previous cut, there was no significant pain from the wound this time.

To use a metaphor, it's like being bitten by a girl with her little tiger teeth.

It is far from the level that just made Gao Gao die in pain and hysteria.

"Am I a masochistic physique?"

Gao Gao was taken aback by the idea of himself, meaning to give himself two knives, and he actually discovered his evil nature?

He shook his head vigorously and threw out the cranky thoughts in his head, he didn't want to bear such a disgusting person and give himself goosebumps.

He is tall but a straight man with a normal orientation and no bad habits......

"Maybe it's because they've had trauma before, so nearby neurons are immune to the same trauma, so they don't feel that much pain?"

Gao Gao can only comfort himself like this, or is there another reason?

"Is it because 'photosynthesis' produces starch, which makes your skin tend to be planted, so it reduces sensitivity?"

This is also possible, after all, he has no standard answer, and all the aspects that can be thought of are worth exploring and verifying.

Picking up the pen, Gao Gao added another sentence in the notebook: The skin has a tendency to be planted, and the certainty is doubtful, pending verification.

After writing this text, Gao Gao looked up to see the wound on his left arm.

"Huh, it's going to heal so soon?"

In just a few minutes, the 2-centimeter wound that had just been cut has healed almost half of it, leaving only a small wound with a little finger capped wide.

And the amount of blood that came out this time was much less than last time, and there was basically a little mark around the wound.

If you wait for the wound to heal and then wipe it with your hand, you won't see that there has ever been such a hole here.

Gao Gao stared intently at the wound, and he was very curious: what a wound that heals quickly looks like.

Under his gaze, the tiny wounds that existed slowly healed at a speed visible to the naked eye.

It's like a child's small mouth, after sucking breast milk, the moment when it is about to fall asleep, it gradually closes from the inside out.

First, the internal subcutaneous tissue is connected together, and then the most superficial layer of skin closes little by little from the two ends to the middle, like a zipper, and it is a double-ended zipper, which is pulled from the two ends to the middle.

By the time the zipper was finally closed, the wound was gone.

Except for the little blood that had soaked out before, it was as if nothing had happened.

Gao Gao stretched out the index finger of his right hand and rubbed it twice, without any pain, without any abnormality, not even a scar.

Gao Gao, who did not believe in evil, picked up the knife and gave it to his left arm again, this time the wound he cut was much longer than the last time, about 10 centimeters long.

After putting down the knife, he stared at the wound to see what a different view would be this time.

It may be that the skin tissue or human body has become resistant to the incision, and the visual effect this time is even worse than the last time.

At least there was blood leaching out of that time just now, but this time there was not even a trace of blood, only a wound, which hung lonely on the little arm, looking lonely and lonely.

"The pain was a little less than last time, even though the wound was five times longer than last time, and it was a little deeper. ”

Picking up the pen, Gao Gao wrote down this sentence again.

The speed of wound healing did not decrease due to changes in the length and depth of the wound, but it healed at a rate visible to the naked eye.

"It seems that the speed of this healing ability is constant and does not change depending on the size of the wound. ”

In order to prove his guess, Gao Gao decided to make a data comparison.

In the next nearly half an hour, he made a total of six cuts on himself.

Two left arms, 2 cm long at one time and 10 cm long at the same time.

There are two internal tests on the left thigh, one with a length of 2 cm and one with a length of 10 cm.

Two belly stripes, 2 cm at one time and 10 cm at the same time.

He also used the stopwatch on his mobile phone to make statistics on the healing time of each wound.

The results were as follows: regardless of location, regardless of the size of the wound, the healing time was fixed at 7 minutes and 41 seconds.

This phenomenon once again breaks the high scientific understanding, which is not in line with common sense.

"Something must have gone wrong. ”

The only explanation for this phenomenon is that his human cells have also mutated and become extremely vigorous.

When an average person is injured, the body's cells will repair on their own, but this process is relatively much longer.

As for him, for some reason, the cells have mutated, and whenever his body is traumatized, the human cells will spontaneously carry out rapid repair, and it is a hysterical kind of repair.

Why did you use the word hysteria, this is also Gao Gao's own speculation.

For example, if an ordinary person is injured, the cells involved in the repair may only be those around the wound, and the repair ability of the human cells is extremely weak, so it takes a long time.

After his own cells have been mutated, they have extremely powerful self-healing abilities, and whenever a wound appears, all the cells related to it will participate in this repair project.

If that's the case, it probably makes sense.

So next, Gao Gao has to do another experiment.

Before he could do this new experiment, he had to finish the experiment on the piece of flesh.
