Boom!

Zhao Yunjie and Wei Zhen slammed into the tempered glass door again, but the door still only made a muffled sound, and there was no crack at all, knowing that they had wasted a full three minutes on this door so far.

"Bastard! How so!" Wei Zhen was obviously extremely anxious in his heart, and opened his mouth to say angrily. Obviously, he underestimated the strength of tempered glass, under normal circumstances, the limit of ordinary eight-millimeter tempered glass without deformation and rupture when hit by a blunt object is about fifty kilograms, and when it encounters a human impact, the impact that now disperses the force group, the bearing force is naturally greater, Wei Zhen originally thought that with the joint force of the two of them, he could knock it open a few more times, but now it seems that this is not the case.

Zhao Yunjie no longer used brute force to impact after hitting Wei Zhen several times in a row, he himself was completely different from Ning Jun, his body was not so strong, and lightness was his strength, at this time he was standing in place and obviously thinking about something.

"What do you think? Not in a hurry? Otherwise, the zombies inside will come out, and we will really be the turtles in the urn! Wei Zhen urged beside him.

But Zhao Yunjie was unmoved, but looked up at Wei Zhen and said, "Anxious? ”

When Wei Zhen heard this, he was really angry and said, ", can you not be in a hurry!" The zombies inside are also hitting obstacles, but their collisions are all wooden, and they will come out soon! ”

That Zhao Yunjie shook his head and looked at Wei Zhen with a pair of Chen Jing's eyes and said, "First of all, calm down." ”

Wei Zhen was anxious, stopping the cracking sound of the zombies inside constantly impacting the obstacles, he was really difficult to restrain it, but at this time, Zhao Yunjie's eyes staring at Wei Zhen were wavering, if Zhao Yunjie didn't help, he really couldn't help himself.

"Oops!" Lu Yuan, who had been standing at the entrance of the corridor staring at the zombies inside, suddenly spoke, "The zombies are pushing the obstacles, and now they are slowly moving here!" ”

What the? Wei Zhen twisted his heart, ran over to take a look, the zombies inside hesitated and rushed out of the door, but they were still crowded in the corridor, they were piled up together and there was no way to break through the obstacles, but the expansion of the number was making the obstacles continue to move towards this side!

What to do! Wei Zhen had no idea, and looked at Lu Yuan and Qiu Siyu, the two of them were also staring at Wei Zhen with a look of help, obviously they didn't have any good way.

"Zhao Yunjie, can you help or not!" Wei Zhen said eagerly!

Zhao Yunjie shook his head and said, "Do you really think we can break this tempered glass?" ”

"Gotta try!" Wei Zhendao, obviously driven crazy by Zhao Yunjie's unfazed attitude, even if you are calm, but can't you say it quickly?

Zhao Yunjie said: "At first, I didn't have the same idea as you, I didn't have the idea of breaking the tempered glass, I hit this door with you, just to break the wooden stick outside, but now it seems that this wooden stick is stuck in the doorknob, and it can't be opened by impact." ”

"So what do you have in mind? Say it quickly! Eldest brother! Wei Zhen said. This Zhao Yunjie now seems to be really like the protagonist of the king's tyrant in various novels, except for someone who moves his important people will be abnormal, such as Ning Jun, otherwise he is not shocked to the extreme, and he has some god-like ideas, but he is very slow to die of a group of supporting characters.

"The impact force of tempered glass is very strong, at least fifty kilograms in the absence of a stable fulcrum, if it is just like this, we can still break it, but the two sides of the tempered glass here are stably fixed on the ground, and the ability to resist deformation is greatly enhanced, we can't break it, I tried it with you just now, and the wooden stick outside the door is difficult for us to break...... Zhao Yunjie analyzed, perhaps because of his previous occupation, he has an understanding of tempered glass.

"So what now? Could it be that our idea of treating zombies as turtles in an urn ended up making us turtles in an urn?? Lu Yuan exclaimed.

Wei Zhen on the side couldn't help but blame himself when he heard this, this plan was thought up by him, and now in addition to the fork, even if it is not much with his plan itself, the inexplicable sense of responsibility still makes him feel uncomfortable.

"Which of you has fire?" Just when everyone was feeling desperate in their hearts, Zhao Yunjie suddenly burst out with a sentence.

Fire? "I have!" Wei Zhen immediately took out his lighter, and there was only a little oil left in this lighter, not much left from before he left the mountain where he caught rabbits, and then he used it a few times, and it was obviously about to be scrapped.

"Time is running out, Wei Zhen, you are burning at the corner of the glass! Fast! Zhao Yunjie said.

At this time, there is not much time, Wei Zhen doesn't ask more, Zhao Yunjie has more experience than himself after all, since he said it, he naturally has his reason!

After quickly lighting the fire, he aimed the flame at the lower right corner of the glass and began to burn, and Zhao Yunjie on the side didn't talk nonsense, immediately picked up a broken chair next to him, and smashed it on the center point of the burning! When it was touched, the glass still didn't move, but Zhao Yunjie didn't let go, picked up the chair again and smashed it down again and again!

Is it useful to do so? There was inevitably a question mark in everyone's hearts, and Lu Yuan on the side seemed to be thoughtful and suddenly said, "Oh! I remembered it, I mentioned it in my chemistry class! ”

Wei Zhen didn't have time to take care of him, but Qiu Siyu asked, "What do you mean?" ”

Lu Yuandao: "Tempered glass contains nickel sulfide, and if you use high temperature, you can make it expand rapidly, so that the deformation resistance of tempered glass will be greatly reduced, so it will be much easier to smash it!" And the corners of the tempered glass are also the most fragile! ”

Damn, chemistry is involved?! Wei Zhen couldn't help but scold in his heart, why didn't he listen carefully when he was in school? It's really hard to study, and you can't even smash a window!

Lu Yuan explained like this, everyone knew in their hearts that the hope of survival had greatly increased, even if the zombies in the corridor were approaching, as long as they smashed this tempered glass out of a gap, they could immediately break out of the window!

But the hardness of this tempered glass is unimaginable, and the hardness of the chair itself is not strong, and after more than ten times, it still hasn't smashed a crack, and the lighter in Wei Zhen's hand is getting hotter and hotter, suddenly, with a bang, the crack that everyone is looking forward to did not appear, and the lighter in my hand in Wei Zhen's hand for a long time actually exploded!

The force of the explosion was not strong, but the shattered plastic fragments were all embedded in Wei Zhen's hands, and for a while, the blood in Wei Zhen's hands flowed!

He lit the lighter for too long, and with the eagerness in his heart, the strength to hold the lighter was also very great, and it was normal for the fireer to burst!

"Brother Wei Zhen!" Qiu Siyu Jianwei was really injured, and he couldn't help but exclaim.

And Zhao Yunjie also looked sideways.

"Keep smashing!" Wei Zhen said loudly. The explosion of the lighter was not very powerful, but the plastic embedded in the palm of the hand was unbearable. However, at this time, the situation was urgent, and the eagerness in Wei Zhen's heart far outweighed the pain.

Zhao Yunjie smiled lightly, and said in his heart that Wei Zhen still looks like a man, and the strength in his hand is still undiminished, and after counting it again, the crisp sound of Kara finally sounded, and the glass was finally broken!
