Wu Yi tied the walking corpse several times more, and then used two heavy machines to sandwich him. After making sure that the guy could not escape even if his body was torn into two pieces, he and Xue Zhen walked out of the hut. As soon as he went out, Wu Yi saw Meng Jiawan standing outside with a sad look on his face, holding a few things in his hand, and asked: "Jiawan, what's wrong?" Meng Jiawan didn't say anything, just handed the things in his hand to Wu Yi . Wu Yi took it and took a look, but it was a student ID card and several other documents. The name on the student ID card is "Xu Ning", and the photo shows a very sunny and handsome young man. He was stunned for a moment, and then he remembered the walking corpse in the room that was tied up with five flowers. He trembled in his heart and said, "The one inside?" Meng Jiawan nodded and said, "Well I found it from his coat pocket." "It turned out to be. Students from the Department of Physics of Songjiang University, what a pity." Wu Yi sighed. Songjiang University is also considered a famous university in China, and its physics department is even more famous throughout the country. Its graduates often go to various scientific research institutes to conduct high-tech research. This Xu Ning was admitted to the Physics Department of Songjiang University. He was obviously a top student. Unfortunately, he turned into such a ghost after being controlled by the Ghost King. It is really a pity. Thinking that most of the millions of people in Songjiang had turned into zombies, including everyone¡¯s relatives and friends, Wu Yi¡¯s heart became a little heavy. He whispered: "Put these documents away first, and deal with them with him later." Wu Yi didn't say what "process" meant, but everyone knew it. Once they couldn't learn anything from the walking corpses, and they couldn't keep "Xu Ning" forever, they would have to make some cruel decisions. No one said anything. This is an inevitable choice in difficult times. It may make your conscience a little uncomfortable, but in order to survive, that kind of thing is not important! Returning to the factory with a heavy heart, Wu Yigang planned to ask about the situation of the fortress reinforcement. Wang Yao hurried over, with a long-lost smile on her face, she came to Wu Yi and said: "I have good news and bad news, which one do you want to hear first?" "There has been too much bad news recently. "It's rare to get good news, so just listen to the good news." Wu Yidao. Wang Yao showed her hand hidden behind her back, held something in her palm and brought it to Wu Yi's eyes and said, "Here, look at this." "What is this?" Wu Yi asked strangely. This is an item similar to a monocular telescope, but judging from the poor workmanship, it looks more like a defective product cut from some kind of instrument. A few wires were randomly wrapped around the break, and an external battery pack was connected. It was extremely crude. "You will know after you try it. Where is the switch?" Wang Yao pointed. Wu Yi followed Wang Yao's instructions, turned on the switch, and put the thing in front of his eyes. The world in front of me immediately changed. The whole world became gray and white, but there were many red light spots floating in the air. "This is" Wu Yi was stunned. "Infrared thermal imaging camera." Wang Yao said, "I used an infrared spectrum analyzer from a pharmaceutical factory to modify it. The effect is similar to your sunglasses." "Really!" Wu Yi was pleasantly surprised. This is really good news! The threat of ghost kings is huge. First, they can control and influence people's minds. Second, they are energy bodies themselves and are difficult to detect with the naked eye. ?For most ordinary people. Even before the existence of the Ghost King is discovered, he will be controlled, which leaves people without any resistance in front of the Ghost King. But if traces of the Ghost King can be found, some measures can be taken. Greatly improve the chance of survival when facing the Ghost King. Among Wu Yi¡¯s group, only he and Xue Zhen can detect the Ghost King. Even Wu Nan has to use Yamada Xingryu¡¯s equipment to detect the Ghost King. Under this situation, Wu Yi and Xue Zhen's workload increased dramatically. And no one can replace them, so the two of them always have a sense of tension that they are too busy. If Yamada Xingryu's equipment can be popularized and everyone has a set, it will be much easier to deal with the Ghost King. Everyone can patrol and even have the power to protect themselves. This can not only greatly reduce the pressure on Wu Yi and Xue Zhen, but can even increase everyone's chance of survival dozens of times! Wu Yi looked at the simple infrared thermal imaging camera in front of him in surprise, and said excitedly: "Wang Yao, how did you do this? Who did it?" "Of course I did it." Wang Yao said with a smile, "No. I thought that only Ding Jiejin knew about machines. Although I couldn't handle those bulky machine tools, I studied at the University of Electronic Science and Technology of China, majoring in electronic information engineering. It's not a problem to imitate something like this. " "You actually studied electronics. Information technology?¡±Yi Yi was really a little surprised. He then realized that he still knew too little about women. It turned out that there were secret tricks hidden under every beautiful appearance. "My dad forced me to learn it, and I never used it after graduation. I didn't expect that after so many years, the sword is still as good as it is." Wang Yao said with a smile. "Is this thing complicated? What is the principle? Can the other three things be done? Tell me quickly!" Wu Yi asked hurriedly. Wang Yao briefly told Wu Yi that it turned out that Wang Yao had worn Yamada Xingryu's equipment before. After trying it, she found that these equipment did not have much technical content. The "sunglasses" and "watches" were actually energy detection devices. And the device for measuring radiation can be completely copied using the existing equipment in the pharmaceutical factory. Wang Yao has been tinkering with it for the past few days and finally made a sample today. After testing it, it worked well. After Wu Yi heard this, he probably understood. The Ghost King is nothing more than a kind of energy, which of course cannot be seen with the naked eye. The energy may generate heat and release some radiation, so using an infrared thermal imaging camera can roughly detect the existence of the Ghost King, although it is not too accurate. But it is much better than a black eye! Thinking that Wang Yao had actually solved such a big problem, Wu Yi couldn't help but asked overjoyed: "How many more can you make?" "How many do you want?" Wang Yao asked. ¡°The more, the better. It¡¯s best to have one for everyone,¡± Wu Yidao said. "I'm afraid that won't work." Wang Yao shook his head and said, "There are only two infrared spectrum analyzers in the pharmaceutical factory, and I have already damaged one." Wu Yizheng was a little disappointed, and Wang Yao said again: "By the way, I think of industry There is a company in the park that seems to produce similar infrared equipment. They probably have something like this in their warehouse! " "Where is that company?" Wu Yi almost jumped up in excitement. "Don't worry, I have some bad news yet." Wang Yao said. "What bad news?" Wu Yi asked doubtfully. "I broke the machine toolso I can't process iron plates now." Wang Yao said a little embarrassed. Wu Yi was speechless. Aren't you a top student in electronic information? You can't even understand machine tools? Wu Yi was not in a hurry to go out. He summoned several core personnel to discuss the current situation. I heard that Wang Yao had imitated "sunglasses" and that it was very possible to find a large number of similar devices for everyone to have one. Everyone was very excited. Only Ding Jiejin was silent for a while and said: "Since the Ghost King is an energy body that can be discovered by infrared thermal imaging cameras and radiation detectors, then I speculate that the principle of the laser transmitter is also very simple, which is to use laser to crush the aggregation of energy, thereby To achieve the purpose of destroying the Ghost King." Wang Yao nodded: "That's right. It's the same as my idea. So I have to work hard for Wu Yi. If you encounter any laser equipment, bring it back." Wu Yida said: "No problem But what is that kettle used for? " Yamada Xinglong left four pieces of equipment, "sunglasses", "watch" and laser transmitter. Only the "kettle" that is said to be used to collect energy is unknown. What effect. "Yamada Xingryu said at the time that this kettle can convert the ghost king into harmless energy. You two are more powerful in this area. Please study the use method and principle of this thing." Wu Yi said to Ding Jiejin and Wang Yao. The two girls nodded and said, "Don't worry, we'll take care of it." It lasted a whole day. Wu Yi was making preparations, and he wasn't ready to go out until nightfall. "I'll go with you." Surprisingly, Ding Jiejin actually volunteered. "What are you going to do?" Wu Yi was stunned. "The machine tool is broken, and I have to find a replacement. Also. I have some ideas that need the help of more machines. You don't know much about this, so I can only find it myself." Ding Jiejin said, while subtle He glanced at Wu Yi. "It's very dangerous outside." Wu Yi looked at the sky outside. The zombies are already raging in this area. It would be better for him to go out alone, if he takes Ding Jiejin with him. If you are surrounded by a large number of zombies, it will be really troublesome. But he also saw Ding Jiejin¡¯s look just now, and his heart moved slightly. He knew it was a tease. Don¡¯t think that in such a difficult environment, everyone has no other thoughts. In fact, the more disaster strikes, the more people¡¯s passions rise than ever before. No one knows if there will be a tomorrow, which is why everyone strives to seize every minute to enjoy life so as not to regret it. "Just be as careful as possible. If I don't go, you won't know."How can the machine be used? "Ding Jiejin insisted. Wu Yi stopped insisting. He knew what Ding Jiejin said made sense. "Okay, just the two of us. "Wu Yi finally nodded and said. The two walked out of the factory, and the door behind them quickly closed, returning to the shape of a fortress. Wu Yi checked the surroundings and determined that there were no traces of the Ghost King or the Walking Dead nearby, and then pulled Ding Jiejin walked into a path. The moonlight was shining brightly on the two of them, making their appearance particularly clear. Among the girls, Ding Jiejin had the most unique temperament. Her family was rich and she had an unspeakable strange disease in the past. She has recovered now, but she still has an aloof coldness about her. People who are not familiar with her would think that this girl is too proud and always seems to look down on others. Only Wu Yi knows that Ding Jiejin is like that. A girl who is cold on the outside and hot on the inside is also the kind of girl who will never back down once she decides on something. Among all these girls, she is perhaps the strongest. Looking at it, Wu Yi's heart felt a little warm. He couldn't help but tighten his grip on Ding Jiejin. As if feeling Wu Yi's heat, Ding Jiejin's face blushed slightly and whispered: "Find the machine first" Wu Yi couldn't help but feel a little embarrassed, secretly. Reminding himself that business was important, he pulled Ding Jiejin and ran towards the nearby factory area.
