Inside the old house, five people whispered on a wall and didn't know what to move, and the sound of a squirming drill resounded in their ears. Because there is no light, the whole old house is blinded by black lights, and you can only see the situation inside faintly through the moonlight through the skylight, and a few strange and terrifying cries come from the dead and silent urban village from time to time, and the atmosphere is like a horror movie.

"Xiao Xiao, are you sure this will work? How do I feel like I'm wasting my time? ”

Wu Xiaojing, who looked puzzled, looked at Yang Xiao and Ye Zhenxiong, and the two of them were clinging to the wall to drill holes. The thick walls of the old house are a little moldy, and the old walls are full of yellow traces left over from the years, and Yang Xiao painted a few holes that are more like ghost paintings.

The stuffy old house is like a sauna, and the two big men who are drilling are already sweating profusely

Yang Xiao gasped and said while turning the hole: "You haven't seen the prison break? Don't underestimate these holes, this is called Hooke's law, which is one of the basic laws of mechanics, and applies to the elastic law of all solid materials. As long as we drill through these holes, the wall will become extremely fragile, if nothing else, the coefficient parameters of the material of this wall are in my control, only require the coordinates of x, y, z, to analyze the correct mathematical model, and the establishment of the correct mechanical model will definitely not be wrong! In prison breaking, the male protagonist unknowingly penetrates a wall through this method. ”

Yang Xiao chattered endlessly, everyone didn't know what he was talking about, and Shen Mingyu's ears were about to furle, and he frowned and said: "Okay, okay, big engineer, you can save your energy, I see that you are going to be out of breath, you are too tired, so you will change us to drill for a while." ”

"I'm fine, you learn a little, I'll let you come when I'm tired of Brother Xiong." Yang Xiao wiped the sweat that fell from his forehead.

"I can't see it, you playboy still knows a lot, and you even know what Hooke's law is in physics, and it was rumored in the company at the time that you would only pick up girls and not learn anything, but it doesn't seem to be the case, haha." Wu Xiaojing smiled as if she had discovered a new world.

", do you really think that Lao Tzu's position in the company is mixed up by relationships? I'm the real thing. Yang Xiao laughed and looked cheap.

"Come on, I'm going to heaven with two compliments. I'm curious if we wouldn't have been doomed if it wasn't for the convenience store behind this wall, or if the back door of the convenience store was open and full of zombies. ”

Wu Xiaojing said that for the sake of safety, she quickly put her ears on the old wall, squinting her eyes and listening carefully to the movement behind the wall. Yi Yi saw Wu Xiaojing clinging to the wall, and also leaned on the wall to listen, but the thick wall couldn't hear anything at all, only the sound of Yang Xiao and Ye Zhenxiong's "rustling" drilling......

Yang Xiao sweated like water, shook his clothes and tried his best to cool himself, his hands were a little numb after working for a long time, and said: "There will be no mistake, I have observed, when we came, there was a small store at this end, and the door of the store was locked tightly, as long as this wall was opened, it would be right." ”

"Well, I hope so."

Shen Mingyu replied lightly, waiting for Yang Xiao and Ye Zhenxiong to drill the wall hard, red brick powder continued to overflow from the wall, and the tools sank deeper and deeper......

Silent late night...... I don't know how long it has been, how many times of substitution, with the unremitting efforts of everyone, the force holes on the wall have finally been drilled through! Just when everyone was curious about what would happen next and what kind of movement would be caused, but after waiting for half a minute, the walls were not moving, which made everyone stunned......

"It's... What's going on, why don't you fall after drilling the hole......" Wu Xiaojing muttered with a stunned face.

Shen Mingyu stared at the wall and was also dumbfounded: "Yang Xiao...... Didn't you say that after drilling a hole, you will face the wall and it will fall...... How...... Didn't fall ...... Is it a mistake in the formula? ”

Not to mention, Yang Xiao was also blindsided, walked to the wall with a suspicious face and observed it again and again, and calculated the formula a few times to make sure that he was not mistaken, but the wall just stood tall.

"Impossible, could it be that the material of the wall is different? All the internal stresses of the object that lead to the concentration of forces are reduced!? Yang Xiao pushed the wall with a question mark on his face, but it didn't work at all.

Everyone worked hard all night, but the result was in vain, which made everyone's mood fall to a low point, as if their hopes were dashed.

"So what should I do? You can't wait here, can you...... Isn't this a waste of physical strength......" Wu Xiaojing had a sad face, her body was soaked with sweat, and her hair was scattered on her shoulders.

"Don't worry, something must have gone wrong! Brother Xiong, you look for a hammer in the house, it should be due to external force, we will knock down the wall. Yang Xiao could see that everyone was very anxious, and hurriedly calmed everyone's hearts.

Ye Zhenxiong received the order and hurriedly ran to the house to find the toolbox, rummaged through it, and finally found a hammer the size of a fist. Yang Xiao took the hammer, feeling a little uneasy, listening to the howls of the zombies outside from time to time, this hammer will definitely attract the attention of the zombies in the middle of the night!

Ye Zhenxiong knew Yang Xiao's thoughts, and hurriedly leaned beside him and reminded: "Brother Xiao, you have to think clearly, what will be the consequences if you do this." ”

Of course, Yang Xiao knew the pros and cons, he cast his eyes in front of the window and looked out, a large number of zombies wandered aimlessly in the urban village, like a mentally ill person who had burned out his brain, shaking his head more than during the day, one of the zombies grabbed the mouse that was jumping on his body, opened the bloody mouth and put it in his mouth to chew, and ate it with relish.

Yang Xiao was a little entangled, the big movement would definitely attract zombie attacks, but if he didn't smash the wall, everyone's physical strength would be almost overdrawn, and looking back, everyone had a dry mouth, a weak appearance, and their bodies were obviously dehydrated.

"No matter what, it's come to this point, I can only be a dead horse as a live horse doctor, I hope this iron gate can withstand the attack of zombies."

Yang Xiao clenched the hammer and firmed up his thoughts, instead of stealing a living, it was better to be vigorous, behind this wall were waiting for them countless sweet drinks!

The three girls were pale and solemn. And Yi Yi was even more frightened, and hurriedly covered her ears, her pretty face frowning in panic.

"Bang !!"

With a hammer down, the walls of the old house erupted with a concussive force, and a loud sound echoed in the house, tugging at everyone's heartstrings.

The sound of piercing the night sky made the zombies in the desolate urban village stop one after another, twist their stiff heads, look at the source of the sound with cataract eyes, and open and close the bloody mouth and roar sharply and piercing!

"Bang !!"

"Bang !!"

Two more hammers went down, everyone held their breath, all of them were hair standing on end, Shen Mingyu was so frightened that he was so nervous that he hurriedly ran to the windowsill to observe the situation outside.

"Ho !!"

A zombie suddenly jumped out, screaming through the iron fence of the window, its hideous face twisted, and its bloody hands slapped on the window, shedding a black handprint!

"Yikes!" Shen Mingyu was so frightened that the three souls lost their seven spirits, took a few steps back, and shouted in horror: "Yang Xiao, the zombies are besieging you!" ”

As soon as the words fell, there was a rain-like crash sound from the iron gate, and the zombies guarding the door were furious and restless, sticking to the iron gate's head and constantly knocking into it, making everyone present sweat! As the sound of the iron door slamming became stronger, everyone realized the seriousness of the matter.

Yang Xiao was also frightened, but now that things have developed to this point, it means that there is no way back! In the midst of the gallop, Yang Xiaoqing's muscles burst out, raised the hammer with an angry shout, and slammed it into the wall with all his might!

"Boom~~~"

With a powerful blow, the wall that had become fragile under Hooke's law completely collapsed, and the thick dust and smoke rolled in the old house, choking everyone coughing and not opening their eyes, and when the picture gradually became clear, the hole more than one meter high had come into view, and the wall of the old house was broken into scattered bricks, and the hole went straight to the store!

"It's on! It's on! ”

Wu Xiaojing saw that there was a hole in the wall, and the commissary was close at hand, so excited that she almost shed tears! However, after a short period of excitement and joy, everyone couldn't laugh at all, and the sound made when the wall collapsed just now made the zombies even more violent! Countless zombies surrounded like crazy, slamming the iron gate deafeningly!

Seeing that the situation was so urgent, Yang Xiao didn't care about the joyful celebration, his brain spun quickly, and a pair of eagle eyes quickly scanned every corner of the store! Before the crowd could figure out what he was going to do, he flew into the commissary! After a meal, I found a few bottles of spirits, and ran upstairs to the old house!

"Yang Xiao, where are you going!?" Shen Mingyu shouted, but Yang Xiao didn't look back, and rushed towards the roof of the old house.

Everyone hurriedly caught up, and on the roof, they saw that Yang Xiao actually made *** with high spirits, and quickly ignited it and threw it far away from the streets of the urban village!

"Bang dang~~~"

With a crisp sound, *** smashed down the street and ignited a raging fire, Wu Xiaojing was stunned, and just wanted to ask Yang Xiao why he didn't throw *** to the zombie group downstairs, and the doubts in his heart disappeared!

I saw Yang Xiao grab a few handmade *** and quickly ignite them and throw them into the street, the glass bottle smashed down and ignited a raging fire on the block, which quickly attracted the attention of the zombies! The group of zombies who were still downstairs and hit the iron door just now, when they saw the fire in the distance, they all stretched out their arms and rushed towards them with their teeth and claws, and each zombie became extremely excited, and in an instant surrounded the block, as if it was a bonfire party!

Those living corpses who didn't know the power of the flames rushed into the fire at the risk of death, the clothes on their bodies burned instantly, and the flames engulfed their bodies at the same time, billowing up smoke, like a living fire man!

Yang Xiao undoubtedly saved everyone's lives by doing this, if he rashly threw *** downstairs, not only could he not stop the attack of the zombies, but he might attract a large number of zombies! It is even possible to set the house on fire, and everyone will hold a pot of cooking!

Watching the zombies rush into the pile of flames desperately, Yang Xiao finally breathed a sigh of relief, and couldn't help but admire his urgency. After the nervousness subsided, the whole person softened.

A neighborhood surrounded by fire! Ye Zhenxiong, Wu Xiaojing, Shen Mingyu, and Yi Yi were all shocked by the scene in front of them, and the timid Yi Yi was even more scared to hide behind Ye Zhenxiong, and his pretty face reflected the color of fire! The living corpses roared in the night sky, and the piercing cries of thousands of zombies made people stand up, densely rushing from a distance, rushing into the fire to rush, the picture was extremely spectacular......
