（PS； Twenty-three was a little immobilized, so I waited for five hours of sleep, and then got up to continue fighting. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo）

Deep in the mountains.

After the man in white walked here with the battalion, he suddenly disappeared.

After a long time, Lin Tianyi came here.

"That's where it disappeared, marker."

He muttered in his mouth, but his hand began to move. Put away the tracking monitor, and then take out a set of homemade assassination suits, a short knife, a pistol, and a mask from the backpack, this is Lin Tianyi's assassination suit, although it is simple, but it is very practical.

Although the man in white disappeared with the battalion, he left a lot of traces in the place where he disappeared, and with the experience of the killer who killed the teacher, Lin Tianyi was naturally able to find those clues easily.

Killer, you have to endure loneliness, killer, you have to know how to lurk.

Guarding at the end of the clues found, Lin Tianyi's ambush was a day and a night, eating some compressed food when he was hungry, and drinking saliva when he was thirsty. Other than that, it doesn't move, as if it were a stone, completely integrated into its surroundings.

Finally, the hard work paid off, and Lin Tianyi waited!

It was the man in white who came out, and at this moment he was still dressed in white, and the camp was not by his side.

Lin Tianyi touched the back of the man in white and stabbed the man in white mercilessly with a short knife.

"Whoa!" There was a sound of friction between the short knife and the clothes, and Lin Tianyi's knife did not cut through the clothes of the man in white.

"Did you really change your clothes to special materials after the last time?"

Lin Tianyi thought so, and then put away the short knife.

"Who are you! Why is it here? The man in white took a few steps back in shock, but he didn't expect that someone was ambushing him here as soon as he came out of the secret base.

Lin Tianyi didn't answer him, but greeted him directly.

Seeing that the other party didn't answer his words, and rushed towards him, the man in white couldn't care so much, so he took out a mini pistol and fired two shots at Lin Tianyi.

Lin Tianyi naturally noticed the movement of the man in white raising his hand, so the moment the man in white raised his hand, Lin Tianyi avoided it.

The man in white fired two empty guns, startling the birds in the woods. And Lin Tianyi, taking advantage of this gap, directly slashed at the back of the neck of the man in white with a knife. Although the man's clothes in white have increased toughness and will not be easily cut by blades and other objects, he still can't resist heavy blows.

Under a heavy blow, the man in white was knocked unconscious by Lin Tianyi.

A cave, this is Lin Tianyi came to the world of "Assassination Classroom", inadvertently found in the mountains behind Class E, usually Lin Tianyi does not come here, only occasionally when he feels that he needs to master the assassination technique and comes to practice in the mountains and forests, he will come to this cave to stay.

When the man in white woke up, he found himself tied up in a somewhat cold environment.

The cave was very dark, empty and lifeless, and the man in white could only hear his breathing and heartbeat.

"Hey! Who are you! What the hell do you want to do? The man in white yelled loudly.

Lin Tianyi didn't answer him, but hung him like this.

The easiest way to interrogate a person is to break down the heart of the person being interrogated before the interrogation.

For three whole days, the man in white was tied up by Lin Tianyi and stayed here for three whole days, during which Lin Tianyi stayed here, did not speak, and even breathed very lightly, if he didn't listen carefully, he couldn't hear his breathing at all.

As for the man in white, he was tied to a stone pillar, Lin Tianyi didn't give him water to drink or food, he was abusing the man in white.

"Ask you a few questions, don't talk nonsense to me, I don't have that patience. Otherwise, it will only be the beginning, not the end. Lin Tianyi finally spoke.

The man in white waited for this voice for a long time, his eyes were tied with strips of cloth by Lin Tianyi, it was black and cold, hungry and thirsty, and the whole person was on the verge of collapse.

"I ...... I said, can you give me saliva first. The man in white pouted, he had given up resistance, and if this situation happened again, he didn't dare to guarantee that he wouldn't go crazy.

Tied to a place immobilized, hungry and thirsty, with no sound at all except his own voice, like a person slowly feeling his own death, the man in white would rather have someone kill cleanly than experience that feeling again.

"Your name." Lin Tianyi splashed some water on the face of the man in white and asked.

The man in white was like a new **** with the moisture on his lips.

"Khataro Yanagisawa."

"Khataro Yanagisawa? Identity? Lin Tianyi then asked,

"Scientists." Khataro Yanagisawa replied.

"Scientists?" Lin Tianyi frowned, it seemed that the secret of killing the teacher was about to be solved.

"Tell me everything you know about killing the teacher, I advise you not to hide anything, I will self-evaluate whether you are lying, if you lie, you will think about the consequences." Lin Tianyi said.

Originally, Yanagisawa Krataro wanted to hide something, but when Lin Tianyi said this, he immediately dispelled that idea.

"That killing teacher is actually a human being, and he is not an ordinary person, he is a well-known god of death in the killer world, because of the particularity of the research, I need some special people to be my experimental 'guinea pig'."

"So killing the teacher has become your goal?" Lin Tianyi interjected and asked.

"That's right, we ......" Yanagisawa Krataro told Lin Tianyi everything he knew about killing the teacher without omission, including the biggest weakness of killing the teacher is the heart, as long as the special dagger or bullet destroys the heart of the teacher, he can completely kill the teacher.

However, after Lin Tianyi heard all this, he suddenly lost the desire to kill the teacher.

Yanagisawa Krataro simply hates killing the teacher, and I'm afraid that no one wants to kill the teacher more than him, so in his description, I can't hear any good words about killing the teacher.

But Lin Tianyi is different, after contacting the development of the matter, Lin Tianyi seems to have known the purpose of killing the teacher.

"So, the battalion is just a tool for revenge that you're using?" Lin Tianyi then asked.

"That's right." Khataro Yanagisawa replied.

"Revenge, it's so pointless. Teacher Yukimura's death, although it is not directly related to you, but the indirect relationship is indispensable. It was also because of the death of Teacher Yukimura that he came to Class E of Tsubaki Hill Middle School as a class teacher. And killing the teacher is just to fulfill the last wish of Mr. Yukimura, presumably after that, even if he kills the teacher himself, he will be far, far away from the earth, and he will blow himself up. After all, killing a teacher is a good teacher, and he will do that in order not to hurt his students. So, if you know all this, you want to kill the teacher, not to save the earth or anything, but just to vent your anger, right!? In the face of Lin Tianyi's analysis and conclusion, Yanagisawa Krataro had to admit it, and he didn't dare not admit it.

That's right, he wanted to kill the teacher, not at all for the sake of why the earth would be blown up, but because he killed the teacher and destroyed the experimental base he had spent a lot of money to build, so he hated killing the teacher and made up his mind to kill the teacher, so that he could vent his anger.

"You can reflect on it for me right here." After Lin Tianyi finished speaking, he left alone, ignoring the Yanagisawa Krataro who was still tied to the stone pillar.

Wait for him to open the door of the hidden base as Khataro Yanagisawa said, and then pass through the levels. Finally got out the camp soaked in the nutrient solution.

The battalion that had just come out of the nutrient solution was still very weak, and there was no way to resist Lin Tianyi. could only let Lin Tianyi take him away from the secret laboratory.

Not long after they left the lab, the sound of an explosion resounded throughout the forest. One after another, the entire secret laboratory was blown into slag.

Later, Lin Tianyi released Yanagisawa Krataro. The first time Khataro Yanagisawa regained his freedom, he returned to the secret laboratory. However, all that awaited him was a ruin.
