Pain is caused by nociceptive stimuli that causes tissue damage. Mechanical stimuli such as knife cutting and stick strike, current, high temperature, strong pain and soreness, and strong alkali can all become nociceptive stimuli.

Free nerve endings with the lowest degree of differentiation in the skin and related tissues of the whole body act as nociceptors, convert various energy forms of nociceptive stimuli into certain encoded types of nerve impulses. The thinner diameter of slow conduction is myelinated and the thinnest unmyelinated afferent nerve fibers are transmitted through the dorsal root ganglia to the relevant neurons in the posterior horn of the spinal cord or trigeminal nerve tract nucleus, and then pass through the contralateral ventral and lateral cord to the higher pain center - the thalamus, other brain areas and the cerebral cortex, causing pain sensation and response.

Usually, the human body cannot resist pain. When the pain reaches a certain level, the body's self-protection mechanism will cause the body to experience a series of behavioral characteristics such as twitching, spasm and other behaviors.

The reaction Xiao Yuanchao made at this time was the self-protection characteristic of the body because of pain. As long as he was a normal person, he could not resist the reaction brought about by the natural physiological phenomenon of pain.

Xiao Yuanchao secreted too much adrenaline, which made his perception stronger. In other words, Xiao Yuanchao was afraid of pain than ordinary people.

As he twitched, Xiao Yuanchao had to fight all his strength to turn his body over and lie on the ground, using this method to relieve the pain of the knife laceration wound.

He wanted to resist, but unfortunately he could not suppress the trouble caused to him by the pain. He was pulled over by a madman like a lamb who had been waiting to be slaughtered and stepped on the handle of the knife on the shoulder of his back.

"Um!!!……"

The hilt of the knife was trampled, and it was trampled upwards, and immediately teared Xiao Yuanchao's piercing wound on his shoulder again.

Blood flowed outward along the piercing wound, and at this time, all Xiao Yuanchao could do was to tighten his body, stretch out his five fingers to hold on to what he could catch, and use this method to fight the pain.

The madman looked at Xiao Yuanchao coldly under his feet, and a smile appeared on the corner of his mouth. He took out a saber and bent down, using the tip of the saber to press against the joints of Xiao Yuanchao's cervical vertebrae.

This is one of the few fatalities in the human body. As long as the tip of the knife penetrates three centimeters into the flesh, it will completely destroy the central nervous system. It may not die, but from then on, the part from the neck down will completely lose its intuition and become paralyzed in bed.

In such an occasion, losing motivation means being killed without any effort.

Faced with the inevitable death, Xiao Yuanchao tried hard to take deep breaths and kept looking for a way. Unfortunately, no method worked, because he had lost all his strength now, or he could no longer resist.

The coldness on the cervical vertebrae made him unable to resist. Any resistance would speed up the arrival of death, and his speed could not be faster than the speed of sending out the sabre gently.

This madman actually used this method to confuse his enemies, and his mind was so careful that he was terrifyingly careful.

"I can't tell that you dare to remain kindness here? Hahaha..." The madman chuckled and said to Xiao Yuanchao with mockery: "It's just a dead person, a female corpse, and it's a female corpse you killed with your own hands. Hahaha... I think this is contrary to morality and ethics? I think that dead people also need dignity? You are too conflicted, kindness and viciousness alternate, and I don't know which point should dominate. It's a pity, it's a pity, it's a pity that you are a real strong man, hahahaha..."

"It's human nature!" Xiao Yuanchao gritted his teeth and let out a low roar: "At least I know I am still alone, at least I can't do something that you loses humanity!"

How can a person rob a corpse? Can a person who does that kind of thing still call a human? That is an insult to a higher wise creature like a human. The principle of human nature is that it cannot make a meaning that violates the existence of a higher creature like a human.

"Humanity? Hahaha..." The madman laughed as if he had heard the best joke, and licked his lips and said, "You are human, so you are destined to not be able to survive here. You can open your eyes and look around. Who is human? As long as you can kill your opponent, any method can be taken, even if... I pretend to be crazy and stupid, and I am traitoring like this, hahahahaha..."

This is a madman, a complete madman! He pretended to be a madman with chaotic logic, and his true essence is a madman with inhumanity.

It is true that that woman was killed by Xiao Yuanchao, but if he doesn't kill that woman, he will die. I'm afraid everyone will tell whether others or themselves will die.

But people die when they die, no matter who they are. People die for peace, and people die for the greatest. This is a collision of kindness and cruelty? No, this is just the most basic manifestation of the failure of human nature, and it is just a manifestation of the most basic ethics and morals of human beings.

Xiao Yuanchao admitted that he did something wrong and stood up for the sake of a person he killed. But he did not regret what he did, because Xiao Yuanchao had never made any regretful moves about his actions.

"Do it." Xiao Yuanchao relaxed his body and lay on the ground, making a bitter sound.

But the redness in his eyes was burning, surging; his right hand pressed on the mountain in front of his chest, quietly pulled out the pistol in his arms, pressing his chest tightly, locking the madman through his body.

In this case, the pistol bullet will definitely penetrate the body. After piercing, the remaining force will continue to cause secondary damage. With the penetration of the pistol bullet, it may not be killed, but it can definitely be seriously injured.

Here, serious injury means death.

If you want to die, let's get lost together!

Even if Xiao Yuanchao dies, he will have to find a way to get a burial person. He will pierce his heart and let the warhead complete the second injury to the enemy. No one can be more cruel than him, and no one can be more amazing than him!

"Learn to be smart in the next life..."

"Bang!"

Before he finished speaking, a dull and bulging sound came to Xiao Yuanchao's ears. Immediately afterwards, the cervical vertebrae was pressed tightly by the tip of the knife disappeared, and a bloody rain poured down, blowing one after another.

The power of stepping on the hilt of the wound disappeared, Xiao Yuanchao immediately pulled the ground and rushed forward for a distance, instantly lying on his side, turning his head to the madman and raising the gun in his hand.

When he saw the madman's body, his pupils contracted violently into the most dangerous needle-like shape, staring at a fist that emerged from the madman's abdomen.

The fist is very ordinary, the fist of an adult, but the fist is tightly pinched.
