In the dim candlelight, a hideous ballista was slowly pushed out, 100mm long, 70mm wide, and 80mm high, with a bow at the top and a simple rubber tire at the bottom, but it was undeniable that this ballista was definitely the most powerful weapon in Youxi's hands right now.

"This ballista was barely assembled by me from some materials I collected, but unfortunately there are no good materials to make the bowstring, so the range is less than 500 meters." Li Haowen explained on the side.

"The range is only less than 500 meters, and if we take into account safety issues, it means that we only have a range of about 300 meters at a time, which will have great limitations on our choice of escape routes!" You Xi pondered for a while, and suddenly thought that it was a problem with the bowstring, and hurriedly took out the spider silk collected in the secret room of the supermarket from his backpack, handed it to Li Haowen and said, "I don't know if these spider silks are suitable to replace the bowstring?" ”

Li Haowen saw You Xi take out a bundle of white thread from his backpack, thinking that he would have some good materials, but when he heard that it was a bundle of spider silk, he thought that You Xi was joking, and took the white thread in You Xi's hand suspiciously, and pulled the thin thread in his hand hard, the toughness was unexpectedly good, and then he thought of something, and said with a surprised face: "This is mutant spider silk?" ”

"Yes, it seems that Mr. Li also has a certain understanding of mutant creatures, but he doesn't know how far these spider silk can reach if he replaces the bowstring?" You Xi was not surprised at all that Li Haowen knew about the existence of mutant spider silk, because he had already guessed that Li Haowen's origin was not simple.

"Hehe, I don't know about the existence of mutant creatures, if my guess is correct, Mr. You should be an evolutionary!" Li Haowen looked at You Xi and said with a smile, and then looked at the spider silk in his hand with a crazy gaze, "1000 meters, I dare to guarantee that the range will be at least 1000 meters, and if all the creatures in the world mutate, with the collected biological materials, our country's individual combat weapons will be raised to a higher height!" ”

Seeing Li Haowen's somewhat crazy appearance, You Xi didn't understand what these people who were engaged in research were thinking in their heads, as if the world had become like this was a happy thing for them when they came, and Li Haowen's subordinates also shook their heads helplessly.

"I'll finish the conversion of the ballista tonight, but these spider silks are a very precious material, more than enough to make bowstrings, and I will return the rest to Mr. You, but I beg Mr. You to provide me with some spider silk for research." Li Haowen looked at You Xi expectantly.

You Xi didn't expect that these spider silks would really be so precious, but no matter how precious they were, they would have to fall on the people who would use these materials, so they would become real combat power, and they didn't refuse Li Haowen's request, and then the group returned to the office.

In the office, Li Haowen and his men were modifying the ballista all night, while Zhang Xiaoxiao and You Xi were discussing the route to escape the city, of course, after tonight's incident, they did not dare to relax their guard, and two people were guarded at the door of the office at any time.

……

The next morning, You Xi woke up, looked at Leng Xue who was still asleep on his shoulder, couldn't help but smile on his face, raised his hand and wanted to touch Leng Xue's forehead, but his hand was fixed in the air halfway up, the expression on his face became stiff, and his eyes looking at Leng Xue suddenly seemed to be looking at a tigress, because he thought, which Leng Xue will wake up this time, will he be kicked again?

"It's done! Haha......" The office suddenly remembered Li Haowen's laughter, and the rest of the people were woken up by this laughter, and they opened their eyes to look in the direction of Li Haowen, and Leng Xue was not surprised. Looking at the cold snow that slowly opened his eyes, the corners of You Xi's mouth twitched, as if a sick child had to accept the reality of taking medicine.

"Brother You Xi, what's wrong with you, are you not feeling well?" Leng Xue woke up and saw You Xi's face a little pale, and asked with concern, raising her slender white and tender right hand and touching You Xi's forehead.

"Whew!" You Xi breathed a long sigh of relief when he saw Leng Xue's reaction, at least now Leng Xue's reaction shows that he doesn't have to take a kick every day when he wakes up in the future, and then looked in the direction of Li Haowen and said, "I'm fine, it's just that I was on duty late last night." ”

Then everyone who woke up walked to the place where Li Haowen modified the ballista, at this time Li Haowen was holding two big panda eyes, and he was excitedly stroking the ballista on the ground, it seems that he came to modify the ballista all night last night, and even Li Man next to him had two black circles under his eyes.

"1,000 meters, the range is increased to at least 1,000 meters, and now we will have a much faster time to escape the city." Li Haowen's face was full of excitement, and he didn't look like a person who hadn't slept all night. And everyone looked at the ballista on the ground, at this time the ballista has completely changed, the base is directly removed, only a fixed back frame remains, and the bow body has become smaller, so it will be easier to carry.

"Then let's get something to eat and let's go! The green fog outside seemed to get thicker. Zhang Minghai looked at the green mist outside the window and said with a frown.

"yes, we're going to get out of here, the city is getting more and more dangerous, but what about the other survivors in this building?" After all, Li Haowen was soft-hearted and worried about the other survivors.

"Leave them alone, for these ungrateful guys, we have done our best to leave Li Yuan's weapons to them, and they won't go with us." Zhang Xiaoxiao said with disdain, and everyone else nodded in agreement.

"Hey!" Li Haowen sighed, he also knew that those people would only be a burden, so he didn't mention this question anymore,

But there will be accidents in everything, just when they had breakfast to prepare crossbow arrows and ropes, a sturdy woman ran over with a huge hiking bag, the woman was nearly one meter eight tall, stronger than the average man, a little dark, with a middle hair, the most prominent is that the cheekbones on her face are very high, so that people's attention will involuntarily focus on the cheekbones.

"Guys, are you leaving this city? Can you take me with you, I won't drag you down, I'll take care of the food and water. The typical female man said and tightened her fist to expose the strong muscles in her hand, for fear that she would be left behind, and added: "I didn't participate in the siege of you last night, and I have hated Li Yuan for a long time, if it weren't for him, my good friend would not have committed suicide in grief." ”

"Why are you following us, it's dangerous outside, and why are we taking you?" You Xi asked, looking at the woman in front of him.

"I ...... I, by the way, I've been a nurse before, and I think I can treat the wounds of you injured people! The female man thought for a while and said loudly, her voice was almost comparable to that of a classmate of You Xi.

"Okay, what's your name?" Zhang Minghai then opened his mouth to agree, they really need a medical staff.

"My name is Chen Lihua"

In this way, the original team of eight people increased to nine, and then You Xi and the others loaded the ballista, carried it to a pre-arranged balcony, and the three of them pulled the bowstring together and fired at an office building more than 600 meters away.

"Click!" All they heard was the sound of the bowstring flicking, and the bolt had disappeared into the green mist with a rope tied to it.

The rope coiled around the ground was rapidly decreasing, and after a while, it stopped. Li Man tied the rope to the guardrail, tested it with both hands, and after determining the stability and safety of the rope, he put two safety racks with pulleys on the rope, and then said to the people behind him: "Well, no problem, at least two people can go over at one time, I'll go over to check the situation first." ”

"I'll go with you!" Zhang Minghai followed and said, the others didn't stop it, anyway, sooner or later, the two of them sat on the safety rack, and slowly pulled the rope in the air with both hands to slide towards another office building, after more than ten minutes, the hazy building opposite suddenly flashed a red signal light, You Xi looked at them and breathed a sigh of relief, and slowly pulled another string tied to the safety rack, and pulled the safety frame back.

Next is Li Haowen, Li Haowen put a few parts disassembled into a snakeskin bag, and then tied it to one of the safety racks, and successfully arrived at the opposite office building with the ballista.

Next is You Xi and Leng Xue, You Xi took Leng Xue's hand and sat on the safety rack.

"Xiaoxue, don't be afraid, don't look down and often look down, it's okay, I will always protect you!" You Xi grabbed Leng Xue's hand tightly and comforted, and slowly pulled the rope with his other hand, slowly moving to the opposite side.

Time passed like this, and You Xi and the others gradually moved away from the office building, and from a distance, the two of them looked like a couple floating in the green mist.

Coming to the middle of the two buildings, You Xi could already see Zhang Minghai in the office building waving to him, at this time he couldn't help but look around, now a vast land is full of wounds, the black corpses on the ground are slowly shaking everywhere like ants, countless cars collide like toys, surrounded by thick green fog, so that You Xi can't help but feel the insignificance of human beings, in the face of this global disaster, human beings are so vulnerable, the civilization of thousands of years in the past was destroyed in an instant.

Shaking his head, without thinking much, You Xi took Leng Xue's hand and continued to move in the direction of the office building, and not long after, You Xi and Leng Xue arrived at the office building safely, and Zhang Minghai and they stood by the broken window of the office building early in the morning and waited for them.

With his feet on the ground, You Xi looked at the scene in front of him, which happened to be a storage room in the office building, and he didn't encounter any zombies, and the crossbow arrows actually penetrated the thick wall directly and didn't know where to insert it.

After You Xi came down safely, Li Man raised the infrared signal light in his hand and kept shaking, signaling that the next wave of people could come over.

The next group of people soon arrived safely, leaving only Zhang Ziyan and Zhang Xiaoxiao, at this time Zhang Ziyan pulled back the safety rack, and after confirming that the door behind him was locked by them, the two also sat on the safety rack and slid towards the opposite building. After another ten minutes, Zhang Ziyan and Zhang Xiaoxiao also successfully arrived at the office building.

Finally, there is the issue of rope recovery, the rope must be recycled, otherwise even if the backpacks of the nine of them are full of rope, they will not be able to insist that they escape from the city.

The way to recover the rope is to directly use the ballista to shoot the rope tied to one end of the office building, as for the candidate, it turned out to be the eleven or twelve-year-old Lori Zhang Xiaoxiao, which made You Xi and them very puzzled.

After Li Haowen finished assembling the ballista, Zhang Xiaoxiao stood steadily behind the ballista, focusing on the rope opposite the building, a pair of jet-black pupils kept changing, like a pair of eagle eyes, flashing sharp eyes, click, the rope broke in response, making You Xi and them extremely surprised, and they were impressed by the Lori in front of them.

One end of the rope fell to the ground, and the zombies on the ground certainly wouldn't be interested in the rope falling from the sky, so You Xi and the others easily pulled back the rope, and then the group took a brief break and walked towards the next target.
