The rules of the game were confirmed, the players on both sides were seated, and even the uninvited spectators sat quietly.

The competition is about to begin.

Kyogoku Zhen bowed slightly to Lin Xinyi according to the etiquette of karate, and then opened his posture and reported his name:

"Kakuto High School, Extreme Vacuum Jarate, Kyogoku Shin."

The origins, genres, and names are stated one by one, and they are very formal.

Lin Xinyi can't learn this, and his origin is not convenient to report.

"Lin Xinyi."

He only gave his name, and then he went down to the locals and followed with a karate start.

Anyway, according to his personal experience, the important thing in actual combat is to always stabilize the center of gravity and pay attention to improvisation, and it is not very important which genre is used in the starting style.

"You also practice karate?" Kyogoku was really curious.

"Well, Shotokan-ryu karate."

Lin Xinyi reported his karate teacher, the school of dojo instructors who refunded three times the tuition fee and begged him not to come to smash the field.

As he spoke, he added very modestly:

"However, I know a little bit of karate, and I mainly practice Chinese kung fu."

"Oh?"

Kyogoku rarely fights with people who learn Chinese kung fu, and he can't help but be a little interested:

"What genre does Mr. Lin Shinichi practice?"

"Eight poles, Xingyi, Tai Chi, Wing Chun.... Still is? ”

He casually mentioned a few more famous genres, and Lin Xinyi's answer was:

"I know a little bit about everything."

"......." The air was suddenly a little quiet.

"It looks like this contest will be over soon."

"It's a pity, there's no way to see Kyogoku Shin's predecessor take action seriously."

Yona Wada, who was on the sidelines, sighed in disappointment.

"Hey, from Kakudo High School!" Suzuki Sonoko asked with some dissatisfaction, "Why do you see that Lin Xin-sama is going to lose again?" ”

"Do you still need to see this?"

Yona Wada replied unceremoniously:

"If you can do anything, you must be knowledgeable but not proficient."

"Choosing a genre is like buying underwear, only pick the one that best suits your body and wear it to feel comfortable."

"If you try to wear all the underwear in different sizes and styles, you will look like a fool."

"Uh..."Sonoko Suzuki was speechless.

And Lin Xinyi, who claims to "know a little bit", has become the kind of amateur who is completely out of the stream in the eyes of everyone.

Under this strange gaze, the exchange finally began in earnest.

Kyogoku Shin punched first.

He suppressed his power and speed perfectly, but his punches were still sharp.

This punch shows the action style of karate, attacking in a straight line, concise and powerful.

And Lin Xinyi was not in a hurry, and his karate posture changed instantly, and his forearm met Kyogoku's straight fist, quickly winding around it like a spiritual snake.

As soon as the two sides made contact, a dazzling fist exchange followed.

"This..."

The expressions of everyone present changed slightly.

With the same amount of strength, Lin Xinyi can really fight back and forth with Kyogoku.

And although Lin Xinyi's strength and speed are not enough now, it is only when he compares with humanoid beasts like Kyogoku Zhen and Mao Lilan.

The individual strength he is showing now is actually stronger than the vast majority of the contestants present.

"Look, Lin Xinyi is still very powerful!"

Sonoko Suzuki shouted excitedly.

As she spoke, she also deliberately glanced at Yona Wada defiantly.

"Don't rejoice too soon..."

Yona Wada said unhurriedly:

"Don't you see?"

"From the beginning to the present, it is Kyogoku Shin who is controlling the offensive rhythm."

"That Lin Xinyi didn't even find a chance to take the initiative to attack, and he will lose sooner or later if the battle continues."

Karate pays great attention to the control of punch distance, as well as the highly vigilant state of mind known as "Broken Heart".

In actual combat, the master will always accurately calculate the distance between himself and his opponent to ensure that the opponent is always within the most suitable range of his strike.

Therefore, Kyogoku's attack and defense are almost airtight.

Every time he attacked, he could accurately and effectively send his fist to Lin Xinyi, and when Lin Xinyi wanted to attack him, he would always be dodged and blocked by Kyogoku Shin just right.

Yona Wada is right, if this continues, Lin Xinyi will lose sooner or later.

But at this moment...

"He's changed his tactics?!" Yona Wada was slightly stunned.

“？？？” Suzuki Sonoko didn't understand, and looked at Xiaolan for help.

And Maorilan is a part-time commentator:

"Mr. Lin Xinyi, I'm afraid it's a mess."

"He was eager to break through the predicament, so he took the initiative to give up parrying and close the distance, and wanted to fight with Kyogoku Shin senior in close quarters."

"It's actually a desperate way of fighting for injuries... It's fine to face ordinary people, but that's Kyogoku Shinsenpai..."

Under her "prophecy", Lin Xinyi on the field fell into a disadvantage in an instant.

He rushed forward at close range regardless of it, and Kyogoku Zhen blocked it with a punch, and a punch came at him, and he fought back defensively.

Lin Xinyi could only flash sideways, slapped horizontally with one palm, and hit the inside of Kyogoku's wrist.

This slap slapped Kyogoku Shin's head-on arm, but it also delayed the time to dodge - Kyogoku Shin took advantage of the momentum and lifted himself to the ground, hitting Lin Shinichi with a cross knee strike.

"It's... Oops. ”

Even Suzuki Sonoko can see who suffers.

Lin Xin slapped Kyogoku Zhen's wrist, but Kyogoku Zhen hit Lin Shinichi's side waist.

Although Lin Xinyi staggered to his feet and was not defeated by a blow, he was already in decline, and he would definitely be beaten badly next.

But he himself doesn't think so:

"Successful hit..."

"The upper side of the wrist horizontal stripe, the Neiguan acupoint."

Lin Xinyi's gaze was as calm as water, and his movements were always calm.

The trick he is using now is actually the "point point" kung fu he created after learning forensic knowledge.

Yes, point points.

It's just that Lin Xin's point is not the acupuncture points and meridians in the novel, but the vagus nerve that does exist in reality and is all over the human body.

The vagus nerve originates from the medulla oblongata, coils upwards and downwards around the human body, and is distributed in a reticular structure as a whole, which is the longest and most widely distributed pair of cranial nerves.

It governs the senses, movements, and secretion of glands in most organs of the respiratory and digestive systems.

Most importantly, the vagus nerve is a parasympathetic nerve that plays a key role in regulating the heart, and it is closely related to the normal functioning of the heart.

So, when an external force stimulates those nerve-dense areas, even if it is only a very slight stimulus, the reflexes of the nervous system may increase the excitability of the vagus nerve.

It will respond quickly, producing cardiac conduction system dysfunction, coronary artery spasm and other consequences, causing a series of dangerous signs such as bradycardia, arrhythmia, and cardiac respiratory arrest.

The cases of death due to vagus nerve irritation are typical, and the "suppressed death" of sudden death in a short period of time is caused by a very minor injury.

This pattern of death can often look very incredible:

For example, there is one of the most classic cases -

Someone continues to laugh loudly, and the air flow is inhaled in large quantities during the laughter, which strongly irritates the mucous membranes of the pharynx, larynx, trachea, and bronchi.

The stimulation is transmitted along the vagus nerve to the medulla oblongata, and the central nervous system feedback signal impulse is transmitted to the respiratory muscles and glottis, and the glottis and larynx produce spasm, which seriously obstructs or even isolates breathing, and eventually leads to sudden death.

Because the vagus nerve is stimulated, a person laughs himself to death like this.

"The vagus nerve in the inner point of the wrist has been hit."

"So, what's next..."

Lin Xinyi was methodically using the killer moves he had researched from forensic knowledge.

This is a very dangerous trick, if it is an ordinary competition, he will never use this kind of killing move on people, which can kill people.

But Kyogoku is really different, his body is as strong as a monster.

Lin Xinyi felt that even if he tried his best to attack the other party's vagus nerve, it might not be able to cause this man's normal physiological reaction.

Therefore, he has now completely let go of his hands and feet, and has played the life-fighting trick of exchanging injuries for injuries.

would rather take the opponent's heavy blow, Lin Xinyi also wants to point to Jingji's real "dead hole":

"Upper abdomen, five inches above the umbilicus, upper belly!"

The corresponding anatomical position of the upper navel point is the cardia, that is, the upper mouth of the stomach.

The anterior and posterior trunks of the vagus nerve, branches of the abdomen, which branch near the cardia and are divided into anterior and hepatic branches, posterior gastric branches and abdominal branches—the dense parts of the vagus nerve in the thoracoabdominal position.

In 2008, Nei Meng, a 17-year-old high school student, was kicked in the chest and abdomen by a classmate, and the scene was pale, his eyes turned up, his mouth foamed, and he was in a trance, and he was rushed to a flag hospital for examination and death.

"Mid-abdomen, mid-navel, Shenque!"

This is the center of the abdominal solar nerve, and the blow can cause reflexes in the abdominal organs, resulting in a reflex heartbeat and breathing slowing, a sudden drop in blood pressure, and then a temporary decrease in blood supply to the brain, leading to shock.

In 2009, in Gusu, an 18-year-old boy had an argument with a classmate in the dormitory, was kicked in the middle of the abdomen, fell to the ground immediately, and died after being sent to the hospital for rescue.

"Armpits, axillary apexes, Extreme Spring!"

Taking advantage of the fact that Jingjizhen's hand knife fell, Lin Xinyi did not defend, and pointed directly at his armpit.

The Jiquan acupoint, which corresponds directly to the vagus nerve related to the heart, is more dangerous than the previous three acupuncture points.

In 2006, in Yicheng, a 12-year-old child stabbed his companion in the armpit with a toothpick while playing at home.

So far, Lin Xinyi has hit the vagus nerve of the four acupuncture points of Jingji Zhenneiguan, Shangguan, Shenque, and Jiquan.

But having said that, whether or not you can get excited by hitting the acupuncture points is actually closely related to everyone's physical fitness.

These acupuncture points don't kill people when they are clicked, and they don't even provoke a reaction in most cases.

Hitting these parts hard is only a risk of sudden death, which is generally not high in terms of probability.

But Lin Xinyi is no longer an "ordinary person":

After mastering the internal force, even if it was still very weak, he found that he could punch this energy into the opponent's body through contact, adding a little "magic damage" to the "physical attack" of his own point.

In this way, the stimulation of the enemy's vagus nerve by the point will be even more terrifying.

After hitting four acupuncture points in succession, Kyogoku's body may have already experienced symptoms of vagus nerve excitement.

And throughout the process, Kyogoku was really unaware of Lin Shinichi's intentions.

In Kyogoku's view, Lin Xinyi's desperate attacks were not critical, and because the attack was blocked, the strength he finally hit was also limited.

In this kind of injury for injury play, on the surface, it is obvious that Lin Xinyi has suffered a big loss.

He had already received several heavy blows from Kyogoku Shin in succession, and he was no longer able to parry.

"The winner is decided!"

"Kyogoku Shin-senpai won too easily, that guy is completely self-conscious!"

Yona Wada came to such a decisive conclusion.

Mao Lilan shook his head helplessly, and Suzuki Sonoko sighed with regret.

Everyone thinks that Lin Shinichi has lost, and they are all waiting for Kyogoku Shin to play the final "execution move" and end the battle beautifully.

And at this critical juncture...

Kyogoku Zhen, who had been gaining the upper hand just now, suddenly became stunned.

His face turned pale, his breathing became heavy, and his body staggered and could barely stand on his feet.

Lin Xinyi's internal force enchantment version of the scientific point method worked.

He seized the opportunity and stabbed Kyogoku's carotid sinus with one finger - this was where the real death was done.

In 2012, a man in Hunan Province kissed his bride's neck while in a cave room, resulting in the bride's carotid sinus obstruction and sudden death.

(Attention!!) Don't check where the carotid sinus is, and don't press it, the person is almost gone when I press it)

Of course, Lin Xinyi's fatal finger couldn't really hit Jing Jizhen.

At the last moment when his fingertips drove straight into the opponent's vital point, Lin Xinyi also used an inch of retraction method.

He stopped his finger an inch in front of Kyogoku Shin and said:

"I'm sorry, but the winner has been decided."

There was silence in the audience, and the pin drop could be heard.

The onlookers gasped and immediately decided to turn up the air conditioning temperature in the venue.
