The three of them dragged their wounded and tired bodies to the rooftop of the administrative building, where the view was wide, the air was fresh, and white clouds floated in the blue sky. They are not in the mood to enjoy the pleasant scenery now, they just want to get out of the danger of being surrounded by corpses as soon as possible and return to the stronghold safely.

In the center of the roof of the administrative building is a house made of shipping containers, surrounded by many cement piers. In order to prevent the zombies downstairs from catching up, several people deliberately moved these shoebox-sized cement piers to the exit of the rooftop, and spent half a day stacking the cement piers on top of each other one by one, completely sealing the door.

After blocking the door, several people came to rest in the container house, which was a poorly furnished single room, messily placed with many daily necessities, probably where the former school workers lived. After Jiang Xian entered the room, he began to rummage through the boxes and cabinets to find food, and now that it was almost noon, the three of them felt a little hungry.

Cao Yin thought that his backpack was full of medical supplies, and the backpack with food was still in the bushes next to the playground. At that time, he should have put a few more bags in his backpack and took them away, so that he would not starve now, but it was not unbearable, he touched his stomach, and thought to himself, it was just a meal, no big deal.

Jiang Xian fumbled around the room with a wooden stick for a while, and finally used the wooden stick to lift all the sundries on the table to the ground, and shouted angrily and disappointedly: "Fuck it! I haven't found a bite to eat, and I'm so hungry that my chest is pressed against my back now! ”

"Brother Xian, bear with me," Li Mingxian sat on a chair and gasped, "We have hidden all the airdrop materials in the woods next to the playground, there are all kinds of compressed food and drinking water in it, and when we successfully escape, we can ensure that you can eat to your heart's content." ”

"I should have had breakfast today, alas!"

Jiang Xian walked out of the room stupidly, lit a cigarette, squatted on the edge of the rooftop depressedly and smoked, and suddenly shouted for Li Mingxian and Cao Yin to hurry over.

Cao Yin and Li Mingxian walked out of the room and saw Jiang Xian limping towards a corner of the rooftop.

"Mingxian, you see if the escape method that the sniper said is that," Jiang Xian pointed to the front, "He is quite good at playing, and he has long known that someone will attack him from below, so he gave up the exit downstairs and instead used the rooftop as a shortcut to escape." ”

Looking in the direction pointed by Jiang Xian, Cao Yin saw that a zipline support frame was fixed in the corner of the rooftop, but the zipline and pulleys were not installed, and there was a duffel bag next to the support frame.

Cao Yin opened the duffel bag and found that it was full of props for the rappelling zipline, including sling pulleys, ziplines with anchor hooks, barrel rope guns, and some auxiliary and protective equipment.

It turned out that the sniper planned to evacuate the building by means of ziplining, which was indeed a very innovative idea.

Cao Yin squatted and fiddled with these professional props, his brows tightened more and more, he picked up a heavy barrel rope gun, turned to look at the two, and asked, "The rope used for speed skating seems to need to be arranged with an anchor hook, will any of you operate this thing?" ”

"I'll try, I've used it once or twice when I was a soldier before," Jiang Xian raised his hand and said, "The range of this rope gun is less than 300 meters, and since that guy has fixed the support frame here, then the front of the bracket is the rappelling point." ”

Directly opposite the support frame is the street outside the school, and there are several residential buildings connected to each other, the highest of which is only 10 floors.

Li Mingxian pointed to the residential building and said: "You see, the low building opposite is the sniper's preset landing point, that guy is quite thoughtful, I see that there are iron fences on the windows of each floor of the corridor, which is perfect as an anchor point." ”

"I still have a question," Cao Yin continued to rummage through the zipline device in the bag, "I see that the equipment in this bag is only for one person, if the first of us slides down, what will happen to the other two?" ”

Li Mingxian pondered for a moment and said, "At present, the three of us are Cao Yin, you are in the best condition, if you can only choose one person to slide down, I think you are the most suitable, you must return to the bishop's building as soon as possible to bring reinforcements over." ”

Cao Yin said: "Then I'll slide down first, and when I return to the bishop's building, I will definitely bring someone to pick you up as soon as possible." ”

"That's necessary," Jiang Xian said, "I'll equip you with a rope gun, let's try to get it all at once, the zombies below may be attacked at some point, those cement piers can block four or five zombies, if they swarm up, this makeshift wall will be broken down sooner or later." ”

Cao Yin nodded and said, "I will definitely come back, thank you for your trust." ”

After that, Cao Yin took off the backpack and gently placed it on the ground, which contained the zombie vaccine that he valued most on this trip, when he chose to temporarily let Li Mingxian and Jiang Xian keep the backpack, it also represented his determination to come back.

In a few moments, Jiang Xian assembled the rope gun, and the curved and sharp anchor hook was inserted into the muzzle, and its end was attached to the cable coiled in the duffel bag, and the other end of the cable was fixed to the zipline support frame.

The rope gun is aimed at the rappelling point, and then fires the anchor hook, and the rope will fly towards the anchor point under the anchor hook, when the anchor hook can be firmly stuck on the fence, Cao Yin can use the height difference and the sling pulley to quickly slide from the rope to the opposite building.

The most important thing is to ensure the safety of the glide, so it is necessary to carefully check whether the anchor hook is stable after launch, and whether the bracket, waist sling, pulley and zipline are firmly connected until it is confirmed that all the facilities are free of hidden dangers before rappelling. If any fulcrum collapses during the speed skating, the end is unimaginable.

After the three of them completed the facility inspection, Jiang Xian aimed the rope gun at the fence of the low building in front of him, and launched the anchor hook over, the long cable was driven by the anchor hook to extend rapidly in mid-air, and when the anchor hook was hung on the iron fence on the third floor opposite, Jiang Xian fixed the other end to the bracket, and the zipline was set up.

Jiang Xian pulled hard a few times, and even tilted his body back like a tug-of-war, and the anchor hooks on the opposite side were firmly stuck between the iron fences, showing no signs of loosening at all. Jiang Xian nodded in satisfaction and attached the pulley to the zipline.

Cao Yin put the sling around his waist and used the safety hook on it to hang it on the buckle of the pulley, and when the facilities were ready, Cao Yin could only sit on his back and lean against the fence on the edge of the rooftop, ready to start the rappel.

"Get ready," Jiang Xian patted Cao Yin on the shoulder and said, "The props are perfect, there will be no problem, now let your legs and buttocks off the ground, hold the handles on both sides of the pulley with both hands, let your body hang in the air, and I will push hard again, ensuring that you will slide to the opposite side within 30 seconds." ”

"Come on, I'm ready," Cao Yin took a deep breath, then raised his legs, his body gradually hanging in the air, and his heart gradually hanging.

"This is less than a minute," Cao Yin comforted himself, "as soon as his eyes are closed and opened, it will pass!" ”

"Walk you!" Jiang Xian and Li Mingxian each grabbed Cao Yin's shoulder and pushed forward vigorously, only to hear the "squeak" of the pulley, and Cao Yin slid off the zipline.

The zipline is at an angle of 30 degrees to the horizontal plane, and the pulley is equipped with a damping buffer, and under the dual action of gravity and inertia, Cao Yin slides steadily towards the low building opposite.

Feeling the whirring wind and the friction noise made by the rotation of the pulley, in less than a minute, Cao Yin arrived at the low building opposite, and his legs kicked on the fence stuck in the anchor hook at the same time.

"It's here!" Cao Yin finally breathed a sigh of relief, he carefully held on to the cable, then stood firm on the outer edge of the fence, then reached out and grabbed the fence, released the zipline with the other hand, unhooked the safety hook connected to the pulley, and finally jumped from the outside of the fence into the building.

Cao Yin turned around and looked towards the top floor of the administrative building, Jiang Xian and Li Mingxian were waving at him, Cao Yin made an "OK" gesture to them and was about to go downstairs, but saw a little boy appear at the corner of the stairs, he was looking at himself with wide eyes, his eyes were full of surprise and vigilance.

"You...... Who are you! "The little boy was about 12 years old, and he was wearing a dirty beige jacket, and his little hands were holding tightly an iron pipe with a pair of scissors tied to the top.

"There are even children in this building," Cao Yin thought to himself, looking at the boy, "Could it be that there are survivors living here too?" ”

"Kid, do you live here?" Cao Yin asked.

"Anyway, I ask you who you are and why you slipped down the building of the school opposite?" The boy's expression was obviously hostile, and the scissors on the iron pipe trembled slightly and aimed at Cao Yin.

"Because we were trapped, the building opposite the school was now full of zombies," Cao Yin said, "so I had to escape from the upper floors with the help of gliding props." ”

The hostility in the boy's eyes did not abate, and he continued to ask, "Are you the dog leg of that hooligan organization?" ”

"Rogue organization, you mean the rainstorm?" Cao Yin remembered that the old owl had said to himself that the city's largest gangster organization, "Heavy Rain", even if the zombies besieged the city, they dared to run rampant, burn, kill and plunder, and it was an extremely arrogant villain group.

"The devil knows what they're called," the boy snapped, "whether you're or not, tell me!" ”

Cao Yin shook his head.

"You don't look like a thug," the boy looked at Cao Yin and said mockingly, "They usually carry guns and machetes, and if you encounter one, you won't survive the next day." ”

Cao Yin snorted disdainfully, and didn't intend to have a verbal argument with him, and said: "Child, I'm busy on the road, since this is your territory, I won't bother, can you not aim your weapon at me, I won't hurt you." ”

"This is my territory, you are right," said the boy, "I am in charge of my territory, so you have to keep the money for the road." ”

"I don't have anything with me," Cao Yin patted his pocket, then removed the shovel from his back, and said, "If you like this shovel, I can give it to you." ”

"Whoever wants your broken shovel," said the boy, licking his lips, "must give me a piece of meat if you want to pass through here." ”

"I don't have any meat on me, but I know where there are canned meats, and if you want to eat them, I'll bring you some when I get back." Cao Yin said.

"You can pull it down, who wants to eat something disgusting!" The boy said, "I want to eat human flesh, which is your flesh!" ”

"Are you so hungry, no matter how hungry you are, you can't eat human flesh!"

"I eat human flesh purely to satisfy my hunger and maintain my health by the way," the boy's eyes showed a greedy fierce light at this time, "Look at your fine skin and tender meat, the thigh meat must be very fragrant when roasted, the viscera and blood sausage can be marinated and eaten, and the remaining bones can be used to make soup, hehe." ”

"You've been driven crazy, what a poor child," Cao Yin shook his head and sighed, "Don't worry, when my brother and I come back, I will definitely bring you something delicious." ”

"Hey, it looks like you don't know your situation very well, brothers, don't hide it, come out quickly!" The boy suddenly clapped his hands and shouted, "I finally caught a living person, how could I let you out!" ”

Cao Yin felt the signal of danger, he could already see that this little boy saw himself as a prey, the hostility and vigilance in his eyes had never dissipated, and now his expression was becoming more and more hideous, not at all like an expression that a child could make.

At this time, many children appeared behind the little boy, but all of them had hideous faces, fierce eyes, dirty and stinking all over their bodies, and the most strange thing was that they were all prostrate on the ground, crawling on all fours.

These strange children were like the children of uncivilized beasts, constantly grinning at Cao Yin, their palms and soles of their feet grew sharp claws, and a few children even stuck their claws against the wall, slowly approaching Cao Yin like geckos.

"Little cubs, bite him to death!" The boy waved the steel pipe in his hand and shouted, "We can have a good meal today, and whoever kills him first, I will give this guy the most tender meat!" ”

"Whew!" The children who were walking on the ground began to howl excitedly, and then rushed towards Cao Yin in unison.
