"Open the door." Li Yan stood in front of the iron gate and took a deep breath. "You must enter the passage within five seconds, and then pass within thirty seconds, otherwise the door of the laboratory will not open" Xiaoxue suddenly said. "I know." Li Yan said with a thought, the dragon-slaying knife disappeared from his hand. He could have asked Xiao Shui to go in with him, but Xiao Shui is a zombie. If the system identifies her as a zombie, then It would be big trouble if he didn't let him out. Although it wasn't necessarily the case, it was a risk he couldn't afford to take. "Ding!" With a crisp sound, the closed door opened, and Li Yan jumped in without thinking. With a "bang", the door behind him closed. But at this moment, he lowered his head and sprinted forward with all his strength. After running for a while, he reached the end. The passage did not seem to be long, and there was a door in front of him. He looked at the silver door that was similar to before, wondering what Xiaoxue's hint meant. Looking sideways in confusion, he was so frightened that he almost screamed. There were actually culture fluids on both sides, and inside the culture fluid, zombies with hideous faces were soaked in it, motionless, running through the entire passage, separated one by one by glass, and it was unknown whether they were dead or alive. "The door will open within five seconds. There are no virus infected persons in the disinfection room, but in order to avoid the virus leaking, you only have two seconds to pass through the laboratory door." Xiaoxue's voice came from all around. Li Yan looked up and saw a camera and a speaker just above his head. He hurried to the door. "Ding!" There was another crisp sound, the door in front of him opened, and he jumped in again. "Entering the laboratory, disinfecting" As soon as he entered, there was a burst of system prompts from all around. But it wasn't Xiaoxue's synthesized female voice. As soon as he finished speaking, there was a "swish", and some liquid suddenly dispersed from the top of his head, and there was a cool feeling on his neck. Almost at the same time, a trace of white gas suddenly spurted out from below his knees. Li Yan didn¡¯t pay too much attention. He didn¡¯t need to guess to know that he was disinfecting him at this moment. With a thought, the dragon-slaying knife appeared in his hand again. Xiaoxue said there were only two seconds. In other words, there is only one chance. If there is something blocking the way outside the door, even if it is delayed for a second, all of them will have to wait in this research institute to be blown up to ashes. Soon, the iron door in front of you opened. Just opened. A pungent fishy smell suddenly rushed in, and the disgusting smell made the stomach ache. But he didn't have time to care about that right now. Holding the dragon-slaying knife, he rushed in with all his strength. "Bah! Bah!" As soon as he rushed in, he felt a strange cry coming from all around. When he stood still and took a look, he couldn't stop sweating and fell down. Around him, several bucket-sized bugs hunched over and stared at him. These bugs were not much different from those on the top of the coffin cliff. They should be corpse crystal mother bugs. But it was obviously larger than those. The top of the insect's head was split into several lobes, each of which was covered with tiny fangs, and the fangs were covered with sticky liquid. The mouth kept shaking, and the sound just now should have come from there. Just when he saw it clearly, the bugs even squirmed and pounced towards him. "Fuck!" Li Yan couldn't help but swore, and slashed at the nearest corpse crystal mother worm with his dragon-slaying knife. Unexpectedly, the insect's huge body shrank back quickly and escaped. Digging, flexible fat man! He cursed in his heart, his whole body fell to the side, and a carp rolled out of the way. A strong gust of wind passed over his head. "Bang!" Where he was originally standing, the insect's whole head hit the ground, and the iron floor was directly smashed into a big dent. Li Yan stood up suddenly after turning over. When he saw the big dent, he couldn't help but take a breath. The floor was a solid iron plate of forty to fifty centimeters! The insects turned around suddenly, their mouths trembling and looked at Li Yan again. Li Yan couldn't help but take two steps back and tightened his grip on the dragon-slaying knife. The situation was not good! At this moment, he paused and his waist seemed to hit something. He glanced and saw Song Yunfei's head turning over, but he didn't have time to control the vomiting in his stomach now. Inexplicably excited, the random roll just now actually rolled to the edge of the test bench "ßÚßÚ" Those corpse crystal mother wormsThe butt was trembling, and it looked like he was about to attack again. Li Yan suddenly turned around and quickly picked up a test tube behind him. Fortunately, there was a stopper on it. After getting it, he quickly stuffed it into his arms. At this moment, the insects swooped up with a strong wind. , completely unavoidable. "I'm sorry, Professor Song." Li Yan muttered to himself, and without any hesitation, he directly picked up the body of Song Yunfei next to him and attacked the flying insects. "Bahba" Those huge bugs let out an excited roar, biting the flying corpse with their mouths, and let out a joyful cry. "Bah, bah, bah!" After a burst of rags, Song Yunfei's clothes were torn to pieces, revealing what was inside. They were actually insects entangled with each other, but they were obviously smaller than those outside. On several numbers. "It's true." Taking advantage of the time just now, Li Yan bent down from under the insects and ran to the exit of the laboratory door. The door suddenly opened, and he looked at the familiar The scene murmured, then jumped into the disinfection room, and the door behind him was quickly closed. "Disinfection in progress" A familiar voice came, and the sprinkler head above the head began to spray the disinfectant liquid repeatedly, and the soles of the feet also began to spray white disinfectant gas. Finally, there was no danger, and Li Yan couldn't help but let out a sigh of relief. "Bang!" At this moment, there was a fierce crashing sound from the door behind him, and the iron door was knocked directly into a big bulge. "Bang! Bang!" There were several more violent impacts, and the bulge on the iron door was getting bigger and bigger, but the impact had no intention of stopping. I was afraid that the opening would be broken within a few times, even if it didn't break. Damn it, the door is probably going to be blown off as well. "Hurry, hurry" Li Yan shouted in his heart, staring in the direction of the door in front of him. But the door, I don¡¯t know why, is motionless at the moment. At this moment, in the computer room of the research institute, Sun Congsheng had been arguing with Xiaoxue for a long time. "Why don't you let him out? What happened to what you promised just now? Do machines lie to people these days?!" Sun Congsheng was almost roaring. "Xiaoxue's highest-level goal is to develop antibodies, but the second goal is to prevent the virus from spreading. Now the system has detected from the previous battle that the people entering the laboratory are not resistant to the attack of the corpse crystal mother worm, and the system will start to automatically Destroy the program" Xiaoxue's cold and analytical voice made people feel as if they had fallen into an ice cellar. "Wait a minute! Why do you say he can't resist the Corpse Crystal Mother Insect? Just based on those battle scenes?!" Sun Congsheng continued to roar. "In terms of quantity, the existing walls of the passage cannot withstand the attack of the Corpse Crystal Mother Insects. If he cannot eliminate all the Corpse Crystal Mother Insects and any one of the Corpse Crystal Mother Insects escapes from the research institute, this is Xiaoxue's fault. Unacceptable" Xiaoxue analyzed still very "rationally". "Digging!" Sun Congsheng finally couldn't help but cursed. Niu Geng, Lin Qian and Li Yin stared blankly at the computer screen, not knowing what to say. On the screen, Li Yan anxiously slapped the iron door with his hand, but the door did not move at all, and the iron door behind him did not move at all. The door has been bumped into holes and may be knocked away at any time. "Xiaoxue, how many minutes will it take for you to analyze the antibody components and synthesize the final antibody?" Sun Congsheng said while looking at the numbers at the bottom of the screen that jumped from 0:31:50 to 0:21:50. "Twenty minutes" Xiaoxue answered simply. Sun Congsheng's pupils suddenly closed, and he said quickly: "As a system, you must obey the first principle. Now I order you to open the door, and then we guard the passage to prevent the corpse crystal mother from escaping. If you can't solve it, you can continue to self-destruct. " "Xiaoxue refuses" Four cold words have already expressed Xiaoshui's answer, and now the number at the bottom of the screen has jumped to 0:21:10. (To be continued)
