After staying in the classroom for a long time, Lu Xing suddenly proposed: "I'm going to go to other teaching buildings to take a look and see if there is anything to gain, Yunfeng, you go with me, let Liu Er guard it here first." ”

"Okay, I'll go with you" Zhou Yunfeng hesitated, then nodded, and then instructed Liu Er: "Liu Er, the two of us are going to go around other teaching buildings, you stay in the classroom for the time being, remember to block the door, and we will come back in half an hour at most." ”

After hearing this, Liu Er nodded again and again: "Don't worry, I will definitely guard here, unless you come back, I won't open the door, but can you give me a weapon for self-defense?" ”

"This bayonet will give you a defence for the time being." Lu Xing stepped forward, threw the stabbing gun in his hand to Liu Er, and then took the lead out of the classroom, and Zhou Yunfeng followed out after taking his things.

Walking to the corner of the staircase, Zhou Yunfeng suddenly stopped and asked, "Say, you specially called me out, what is the matter?" ”

Zhou Yunfeng is not a fool, he can't understand Lu Xing's character anymore, leaving Liu Er alone in the classroom and the two going out together, this kind of thing is not something he will do, in case Liu Er runs away with those supplies, the loss is not ordinary.

He thought of this kind of thing himself, how could Lu Xing not think of it, he felt strange at the beginning, and after thinking about it carefully, he realized that Lu Xing wanted to call himself out, and there were some things that he didn't want Liu Er to hear.

And when Liu Er asked for a weapon, Lu Xing actually gave a stabbing gun without hesitation, which is even more unlikely to be his style of acting.

"How much do you think Liu Er said can be believed?" Lu Xing didn't rush to answer, but asked rhetorically.

"I think it's half true, there are some things he should be hiding." Zhou Yunfeng thought for a moment and replied.

It is impossible for him to fully believe what Liu Er said, he has only known him for less than a day, and it is impossible for anyone to fully believe it, unless that person is too naïve.

"Wrong, at most what he said is true." Lu Xing shook his head, his views were completely different from Zhou Yunfeng's, in his eyes, Liu Er had many problems.

"A person who was controlled by criminals, found an opportunity to escape, ran to this school building, and happened to meet us, and those two people who were chasing him would let him run here so easily? Also, he didn't have any injuries on his body, if he was really controlled by criminals, punches and kicks were indispensable, at least there were bruises, and if the half-dead young man said this, the credibility was still relatively high, and he would forget it......"

Another important point is that when he walked into the classroom before, the moment he saw the young man, his eyes were obviously not right, but he quickly covered it up. When you told him about the young man's situation, he didn't care much, but seemed relieved, and then I quietly noticed that he occasionally sneaked a second glance at the young man. ”

"Liu Er's performance is inconsistent, since he doesn't care about that young man, why do he care so much, what do you think he cares about?" Lu Xing analyzed unhurriedly.

After listening to this, Zhou Yunfeng thought about it carefully, and soon suddenly realized: "What he cares about is the life and death of that young man!" ”

"That's right, that young man should know him and know some secrets, if he dies, it should be what Liu Er wants to see the most." Lu Xing nodded in affirmation.

"Isn't that young man dangerous now!" Zhou Yunfeng's face changed, now there are only Liu Er and that young man in the classroom, and it is the best time for Liu Er to start.

"Don't worry, he shouldn't be easy to do, we haven't been out of the classroom for a long time, that Liu Er shouldn't act rashly, if you want to do it, you have to wait." Lu Xing said calmly.

After the two finished speaking, they squatted down, quietly walked back to the stairs, and with the help of the cover of the corridor wall, carefully went around to the opposite side of the classroom, hid in the shadows, and then picked up the night vision binoculars to observe Liu Er's every move in the classroom.

At this time, Liu Er was sitting by the fire, his eyes looked at the young man next to him from time to time, as if he was hesitating something, and after waiting for a few minutes, he suddenly stood up, walked to the window and opened the window, stretched out his head and looked left and right a few times, and closed the window after making sure that there was no one.

Soon, Liu Er picked up a curtain cloth and walked towards the young man, squatted down, covered his mouth and nose with a piece of cloth, and pressed his hands on it, wanting to suffocate him to death, so that he would not leave scars, and it would be easier to explain at that time.

"Let's go! He did it! Seeing this, Zhou Yunfeng immediately put down the telescope.

Next, they deliberately made loud footsteps and walked to the classroom as if nothing had happened.

Suddenly hearing footsteps, Liu Er was startled, hurriedly picked up the cloth, threw it aside, and then quickly sat down next to the fire, pretending to be casual, and adding firewood from time to time, until Zhou Yunfeng and Lu Xing appeared at the door of the classroom.

As soon as the two returned, Liu Er immediately went over to remove the things blocking the door and let them enter the classroom.

"Why did you come back so soon, did you get into some trouble halfway through?" Liu Er asked suspiciously.

As soon as the words fell, Lu Xing had already gone around Liu Er's back, suddenly moved his hand, clasped his hands from behind, and kicked him at the knee joint, making him half-kneeling on the ground.

Seeing this, Zhou Yunfeng also moved to control it, and finally took the rope and tied it up.

"What are you doing here?" The sudden change suddenly made Liu Er stunned.

"The two people who chased you before should be in the same group as you." Lu Xing stood in front of Liu Er and asked expressionlessly.

"I don't know what you're talking about, how could I be in league with them, they're going to kill me!" When Liu Er heard this, he looked flustered and quibbled.

Zhou Yunfeng couldn't help but shake his head when he heard this: "Don't act, you can't deceive us with your tricks, we didn't leave the teaching building just now, we just watched you in the opposite corridor, we all saw your intention to kill, is there anything else to say now?" ”

Liu Er's face changed suddenly: "When did you start suspecting me?" Didn't I show my feet somewhere? ”

"Your bitter idea is good, but it's a pity that your acting skills are not very good, and you haven't thought it through before, there are so many flaws, I don't talk nonsense with you. Say, what is your purpose, and who is that young man? "Lu Xing

A sly smile appeared at the corner of his mouth, and he said unhurriedly.

"Hmph, if you want to kill or chop you as you please, don't try to know anything from my mouth." Seeing that the matter had been revealed, Liu Er no longer quibbled, but he did not mean to be soft, and his tone was very tough.

Zhou Yunfeng was a little surprised, he didn't expect Liu Er to have such guts, he looked at Lu Xing and said, "You should have a way to make him speak." ”

"No problem." Lu Xing nodded confidently, and then said, "First strip off his clothes, throw them outside the classroom for a few minutes, and then fish them in." ”

“…… You don't need to strip them all naked. Zhou Yunfeng was a little speechless.

"Then leave him a pair of bottoms......"

Next, Zhou Yunfeng took off Liu Er's thick cotton clothes until only a pair of boxers remained, and then pulled him to the door of the classroom.

As soon as the door opened, a cold air suddenly blew in, making Liu Er shiver.

Taken outside the classroom, the low temperature of nearly minus 40 degrees, coupled with the cold wind, made him shiver as soon as he came out, his teeth chattered, in this low temperature, a person without clothes absolutely unbearable, soon died of hypothermia.

"It's about two and a half minutes, it should be fine."

Zhou Yunfeng also watched in the corridor, silently calculated the time, and felt that it was almost there, so he pulled Liu Er back into the classroom and threw him next to the fire.

"Throw him out in five minutes and repeat the process until he wants to speak." Lu Xing said.

Zhou Yunfeng nodded, knowing Lu Xing's thoughts.

A person is repeatedly experiencing this feeling of ice and fire, which will inevitably cause a certain degree of mental blow, which is much more effective than torture, and the most important thing is that Liu Er will not be killed, as long as the time is well controlled.

To force something out of the mouth of a person who is not afraid of death, a mental blow is far more effective than **.

In the next hour, Liu Eryi went in and out, going back and forth in the classroom and the corridor seven or eight times, and as soon as he was frozen and almost unconscious, he was pulled in to warm his body, and as soon as he felt warm and comfortable, he was taken out to blow the cold wind.

Every time his body warmed up, the thought of being taken to the corridor again was a mental blow to Liu Er, he didn't think that he would be dealt with in this way, this kind of feeling of ice and fire is not something that ordinary people can bear.

Staying in the cold corridor for a long time, the body will freeze and become numb, but it will change repeatedly, and it is impossible for the body to adapt to it, and every time you go out, Liu Er will be refreshed from head to toe. It's like a person hiding in the quilt in winter, and suddenly someone lifts the quilt and splashes a bucket of cold water.

"Wait! Don't pull me out, I say! When he was about to be pulled into the corridor for the twentieth time, Liu Er couldn't stand this stimulation anymore and finally spoke.

"Now that you've figured it out, let's talk about the answer I asked before." Lu Xing nodded with satisfaction.

"We are indeed all prisoners in the prison, and then there was a big mess in the prison, and I and some people ran out and finally escaped to this university, and our people saw you two entering here, so they wanted to get a crossbow from you."

"But I didn't expect you to have a gun and kill two people, after our boss found out, he thought of such a plan, let me mix in with you, find a chance to do it, and I don't need to say anything after that." Liu Er explained honestly.

"As for the young man with a high fever, I don't know the specific origin, I didn't ask, after we caught him, he used it as a slave to go out to find things, and did some hard work, and he accidentally ran away two days ago......"

After listening to Liu Er's explanation, Zhou Yunfeng asked again: "How many of you are there, and how many others have been caught like this young man?" ”

"There are 13 of us in total, two of whom died before and now only 11, and five more have been arrested." Liu Er replied.

"You'd better not lie, leave you in the classroom for the time being, and when the young man wakes up, I'll ask, and if you dare to lie, then I'll ......"

Although Liu Er confessed, Lu Xing didn't fully believe it, and the best way to confirm it was to wait for the young man to wake up and ask.

If the young man died, he had another way to confirm it.
