The darkness enveloped the underground hall, with only a faint light spreading on the ceiling, and the figures in the distance were blurry, and the only way to see clearly was within a few meters.

Yuki Kyono turned around and looked at Ai Sakurajima, reached out to touch her head: "Don't panic, it's okay."

Ai Sakurajima looked up at Yuki Kyono, with tears of fear hanging on the corners of her eyes. Compared with Yuki Kyono, she participated in the night session of the experiment earlier.

"...Brother Youshu, let's hide in the corner quickly."

"Yeah, OK."

Yuki Kyono forced himself to calm down, but he felt uneasy and more confused.

... Let children under the age of twelve fight each other or something.

Because of my family, I have been practicing kendo, which is definitely considered strong and strong. With a mature mind, I am not afraid of fighting itself.

But I felt heartbroken about the crazyness of this experiment.

His father suddenly told him to come and participate in the summer camp. Does he know these inside stories?

No matter how many doubts you have, you must let go, and necessary actions are urgent.

Yuki Kyono pulled Ai Sakurajima's wrist and quickly moved to the corner of the wall. However, because it was an arc-shaped underground space, there was actually no such angle that the two walls were convenient for defense.

“Woo…”

Ai Sakurajima made a soft cry of pain. Yuki Kyono looked carefully and found that the wound on her palm began to gradually seep blood again.

It has been several days since it has passed, but it has not been cured quickly in this very modern camp with many advanced technologies.

...What's going on with this wound?

"Sister Aiyi, just squat here. Don't be afraid, I will protect you."

While comforting Ai Sakurajima, Yuki Kyono looked around other parts of the underground hall.

...There is no reason why the researchers arrange to fight each other, so they will fight obediently. After all, they are just children...

However, the blurred figures in the distance have begun to attack each other, just like a frenzy atmosphere spreading people. With the attacks of some children, the riots gradually expanded to the entire underground hall and eventually evolved into a battle between everyone and everyone.

"Everyone calm down and stop fighting each other!"

Yuki Kyono wanted to yell like this, everything was so unreasonable.

But at this moment, he just gritted his teeth, clenched his fists, curled up beside the wall of the underground hall, without saying a word.

...Little Aiyi is behind her and can't take risks.

Moreover, he could not take risks. In such a strange state of collective frenzy, Yuki Kyono felt that he could really use words to stop the fight.

Perhaps, if Ai Sakurajima is behind him, he might give it a try.

If he had a bamboo knife in his hand, he would be more confident.

Behind him, Ai Sakurashima squatted obediently by the wall, her shoulders trembled slightly, regardless of the blood from the gauze on her palm, her face was stained with her hands, covering her ears, trying to isolate the crying and crying sounds that filled the entire underground hall.

Yuki Kyono concentrated on his energy and was on guard.

However, Ai Sakurajima's proposal to stay in the corner was effective, and few people came to attack the two of them.

Moreover, with panic, the horror atmosphere spread among the children, eventually forming a distorted and frenzied atmosphere. The fighting movements are more from instinctive revelations than rational judgments. Therefore, few people notice the two people in the corner.

...Maybe, I can wait safely until the end time.

As soon as I had this kind of luck idea, a figure gradually approached.

When he approached, Yuki Kyono saw the other person's appearance clearly. He was a peer who had a little impression of him. At this time, he was gasping heavily, his eyes were covered with blood.

"Don't get closer!" Kyono Yuki immediately warned.

But to no avail, the other party didn't even respond and rushed over in a daze.

Kyono Yuki punched him and accidentally easily hit the opponent's right chin. The opponent's vagus nerve was hit hard and fell down on the spot with a "bang".

"What's wrong with this guy?"

"I, I don't know...but..."

Ai Sakurashima's timid voice came from behind: "But for some reason, everyone will become impatient and irritable after coming here in the evening... Me, I..."

"It's okay, Sister Aiyi..."

Kyono Yuki turned around and saw that Ai Yi seemed to be scared. She reached out to touch her head again, and bent down to her face and comforted her softly: "...I will protect you no matter what the situation is."

Kyono Yuki couldn't help but look at Ai Sakurajima's eyes for a while.

Because he suddenly discovered that the white part of Ai Sakurashima's agile eyes had some blood on his face.

...Crazy, the person who designed this experiment must be crazy. Could it be the influence of the drug?

Yuki Kyono, who could not see his eyes, wondered whether his rationality had also been affected at this time, and fell into deeper concerns.

Then, in the dim environment, it was not only a long time to successfully protect Ai Sakurashima many times and repelled the attackers, Yuki Kyono felt at ease:

...It's enough to last until the end time.

Thinking of this again, a large group of people suddenly burst into screams from the other end of the underground space with a dim vision a little further away.

Then came the whine of pain and the sound of falling to the ground.

... Something must have happened.

But there was nothing else Kyono Yuki except clenched his fists, swallowed his saliva, and looked in that direction quietly.

The disturbing voice gradually approached.

Then I saw that guy, who thought he would be a strong fighting expert, but in the end he was just an ordinary boy with a medium body.

While being fully alert, Kyono Yuki looked around the entire underground space and found that not many people were still standing. Even if there were still people who could move freely, they would avoid it far away.

Ai Sakurajima is behind him, and Yuki Kyono is unavoidable.

As before, you want to use the reaction speed and muscle strength that has been trained far exceeding your peers, and hit the fragile points that can safely knock people out of their lives and quickly resolve the battle.

Kyono Yuki took one step and seduced the opponent to punch.

...Yes, that's it.

Then just use a fake shot to avoid it and hit the opponent's chin from the side. As long as the position is correct and hit the vagus nerve, you can easily stun the opponent.

"bump!"

The right shoulder was hit hard, and Kyono Yuki staggered back a few steps before stopping.

"kindness!?"

...What's going on?

The fist that was obviously able to avoid hit the body.

...It seems that the vision has been shifted.

Yuki Kyono immediately rushed forward again and made a big fuss with the opponent.

After exchanging punches with each other for a few punches, Kyono Yuki's face was also erected, and when the blood of his nose was slowly left, he confirmed it in his heart again.

...It's not wrong. The opponent in his eyes will always deviate.

But, how could this happen!?

There was no time for him to think more, and the other party had already rushed over again.

In this kind of perceptual disorder, Yuki Kyono's skills were not well used and adapted to, and the two of them rolled together for a moment.

Like two real twelve-year-old children, rolling and fighting.

But the simpler one, the one that goes to the flesh.

However, after all, it is just a first-year junior high school child. He is training in the family dojo for a long time. Therefore, Yuki Kyono, who has stronger strength and ability to fight, finally won the victory and successfully knocked down the opponent.

At the same time, the main door opened again, and a square beam of light was projected in. At first, it was a light wave, and then it slowly expanded from bottom to top.

...It's time to end?

Yuki Kyono, who breathed a sigh of relief, also fell to the ground.

Ai Sakurashima immediately rushed over, half-kneeled on the ground, and supported Kyono Yuki: "Brother Yuki! Are you okay?"

...It hurts!!!

Although it is the soft body of a young girl, it will be painful when touching any purple scar.

But seeing Sakurajima full of tears and caring about her appearance, Yuki Kyono endured the pain and smiled: "It's okay, it's okay, I'm very strong. Didn't you see that I hit the other party just now!"

...

...

That night, Yuki Kyono was resting in a bed in the medical area.

Because of taking painkillers and anti-inflammatory drugs, drowsiness quickly entered the brain.

It seemed like someone had come to the bedside in a hazy state.

"…Is this the Kyoto Kendo genius who is highly anticipated?"
