Having learned from his previous experience of cutting himself, Gao Ang's hand holding the knife this time did not tremble violently; in fact, it was quite composed.

It was like the same feeling he had when he slaughtered that pig. No, that's not quite right. He was so scared he almost wet his pants back then. It was more like the feeling he had when he killed another chicken. If I had to describe it in one word, it would be: calm and collected.

With his left hand clenched into a fist and his right hand holding a knife, Gao Ang slashed at the remaining area.

"Um?"

The signal of excruciating pain did not reach his cerebral cortex as expected, and no blood flowed from his arm. The blade remained stuck in his taut skin, unable to penetrate the flesh.

"Could it be that muscle contraction produces an effect similar to hard qigong?"

Gao Ang was slightly puzzled, as hard qigong could be explained using scientific knowledge.

In simpler terms, people who have practiced hard qigong experience localized strengthening of their cell groups and muscle tissues due to long-term training in resisting blows.

On a more microscopic level, people who practice hard qigong have thicker cell walls and smaller intercellular spaces than ordinary people. As a result, when they tense their muscles and withstand external blows, they exhibit the phenomenon that the public sees: they are very resilient.

However, all of this is based on the premise that they must be prepared.

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

To give a simple example, when muscles are tensed, a practitioner of hard qigong can kick a small tree as thick as a bowl in half with a single whip kick.

If he didn't tense his muscles, and instead whipped his leg at a small tree of similar thickness, he would most likely squat on the ground and hop around while hugging his leg.

Thinking of this, Gao Ang loosened his clenched fist with his left hand, and sure enough, the knife went in smoothly this time. After making a wound of about 2 centimeters, he stopped.

Unlike the previous cut, this time the wound did not cause any particularly noticeable pain.

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

It was nowhere near as bad as it had been, causing Gao Feng excruciating pain and hysteria.

Am I a masochist?

Gao Ang was startled by his own thought, which meant that by stabbing himself twice, he had discovered his own evil nature?

He shook his head vigorously to shake off the random thoughts in his mind. He didn't want to be known as such a disgusting person who gave him goosebumps.

He is a perfectly straight man with a normal sexual orientation and no bad habits...

"It's probably because there was a previous trauma, so the nearby neurons have become immune to the same trauma, and therefore don't feel as much pain?"

Gao Ang could only console himself with this thought, or was there some other reason?

"Could it be that 'photosynthesis' produces starch, causing my skin to have a tendency to become phytochemical, thus reducing its sensitivity?"

That's also possible. After all, there's no standard answer, and every aspect that can be thought of is worth exploring and verifying.

Picking up his pen, Gao Ang added another sentence to his notebook: "The skin has a tendency to undergo phytochemical treatment, but the certainty is questionable and needs to be verified."

After finishing writing this text, Gao Ang looked up at the wound on his left arm.

"Huh? It's healing so quickly?"

In just a few minutes, the 2-centimeter wound that I just made has healed by more than half, leaving only a small wound about the width of my little finger.

Moreover, the amount of blood that flowed out this time was much less than last time; there was basically only a trace around the wound.

If you wait for the wound to heal and then wipe it clean, you won't be able to see that there was ever such a cut.

Gao Ang stared intently at the wound, very curious: what exactly does a wound that heals so quickly look like?

Under his watchful eye, the existing tiny wounds healed slowly at a rate visible to the naked eye.

It's like a baby's mouth, which gradually closes from the inside out just as the baby is about to fall asleep after suckling at the breast.

First, the internal subcutaneous tissue connects together, and then the outermost layer of skin gradually closes up from both ends to the middle, just like a zipper, and it's a double-ended zipper, the kind that pulls from both ends to the middle.

By the time the zipper was finally closed, the wound had disappeared.

Apart from the little bit of blood that had seeped out earlier, it was as if nothing had happened.

Gao Ang stretched out his right index finger and rubbed it twice. There was no pain, no abnormality, and not even a scar.

Unconvinced, Gao picked up the knife and slashed his left arm again. This time, the wound he made was much longer than before, about 10 centimeters long.

After putting down the knife, he stared intently at the wound, wanting to see what different sight it would be this time.

It's possible that the skin tissue or the body's mechanisms have developed resistance to the incision, because the visual effect this time is even worse than last time.

At least there was some blood seeping out last time, but this time there wasn't even a trace of blood to be seen. There was only a wound hanging forlornly on his forearm, looking lonely and forlorn.

"The pain is less than last time, even though the wound is five times longer and deeper than before."

Picking up his pen, Gao Ang wrote down this sentence.

The wound healing speed did not decrease at all due to changes in wound length and depth; it continued to heal at a speed visible to the naked eye.

"It seems that the healing speed is constant and does not change with the size of the wound."

To prove his hypothesis, Gao Feng decided to conduct a data comparison.

Over the next half hour, he made six cuts on his body.

There are two cuts on the left arm, one 2 centimeters long and the other 10 centimeters long.

There were two marks on the inner side of my left thigh, one 2 cm long and the other 10 cm long.

There are two marks on the belly, one 2 centimeters long and the other 10 centimeters long.

He even used his phone's stopwatch to track the healing time of each wound.

The results showed that regardless of location or size of the wound, the healing time was a fixed 7 minutes and 41 seconds.

This phenomenon has once again defied conventional scientific understanding; it defies common sense.

"Something must have gone wrong."

The only explanation for this phenomenon is that his human cells have also mutated, becoming extremely vital.

When an ordinary person is injured, the body's cells will automatically repair themselves, but this process is relatively long.

As for him, his cells mutated for some reason. Whenever his body was injured, his cells would spontaneously and rapidly repair themselves, and in a hysterical way.

The reason why the word "hysteria" was used is also Gao Feng's own guess.

For example, when an ordinary person is injured, the cells involved in the repair process are likely only those around the wound. In addition, the repair ability of ordinary human cells is extremely weak, which is why it takes a long time.

His own cells, after undergoing mutation, possess an extremely powerful self-repairing ability. Whenever a wound appears, all the related cells participate in this repair process.

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

So Gao Feng will conduct another experiment next.

Before he could conduct this new experiment, he had to finish the experiment on that piece of skin and flesh.
