The diameter of the ventilation duct is only 60 centimeters. Although Lin Chuan is in good shape, Jiang Ming is a little crowded. ¡°I¡¯m going out to lose weight.¡± He said jokingly from behind, his voice buzzing in the metal passage. Lin Chuan climbed in front with a flashlight and a crowbar, while Jiang Ming followed behind carrying tools and a walkie-talkie. To ensure safety, Zhang Guohui also gave them his pistol. "Be careful." Lin Chuan said. ¡°Perhaps no one has entered here for many years, and there are cobwebs and dust everywhere. Lin Chuan initially tried to use a crowbar to push away the cobwebs, but then he simply gave up. "I hope they're not poisonous," he said silently to himself. Fortunately, when it was designed, the problem of someone entering and repairing it may have been considered. There is a handle in the shaft, otherwise it would be impossible for them to climb up the smooth pipe more than two meters high. Climbing up the shaft, a thick-looking device suddenly appeared in front of you. "Give me the walkie-talkie." Lin Chuan pressed his back and shoulders against the wall, and knocked on the thing with a crowbar. It seemed to be hollow. "Wang Qinian? Did you hear that?" he asked. "What's wrong?" Wang Qinian's voice was muffled. "Have you climbed up the shaft?" Lin Chuan asked. "There is something blocking the road here, what is it?" "Wait a moment." Wang Qinian said, and continued after a while. "I saw it, probably it's probably used to filter the air, to protect against biological and chemical attacks, or something like that?" "Then what should I do?" Lin Chuan asked. "Look around it. There should be bolts for fixing it. You can remove it." Wang Qinian replied. Jiang Ming handed over the tools, and Lin Chuan worked hard in the narrow pipe. "Linchuan, do you hear that?" Wang Qinian's voice suddenly said. "I have taken it apart. After taking off the base, you can flatten it. No problem, you can climb over." "Okay." Lin Chuan replied. "You go first, I'm almost here." After removing the device and handing it to Jiang Ming, Lin Chuan continued to crawl forward, and the "squeaking" sound suddenly became louder. "We have to go back!" Wang Qinian suddenly spoke over there again. "The back of the fan is full of mutant rats. There are too many! There is nothing we can do!" "Wait a minute." At this time, Lin Chuan also saw the exhaust fan that had stopped rotating. Several mutant rats were stuck in the middle of the blades, and their flesh and blood were blurred, but they Still twisting and turning trying to get in. Lin Chuan pushed the crowbar in his hand hard, and a mutant rat screamed and was poked out by him, but another terrifying head quickly filled the gap left by it. The smell of fresh flesh made them frantically want to squeeze through the narrow hole, their white fangs biting in the air. He used a flashlight to shine behind him. The narrow passage was filled with dark red eyes that made people feel terrified. "There's probably nothing wrong with the fans, it's just that they're stuck." Lin Chuan said into the intercom. "I've already gone back." Wang Qinian said. "Remember to put back the device just now. Even if a mouse comes in, it can at least be knocked back." But Lin Chuan did not move. The air here is much better than inside. Although it is less than one meter away from the monsters, Lin Chuan was surprised to find that he was not afraid of them. He used the crowbar in his hand to slowly aim at the eye of a mutant rat, and then pushed hard. The mutant rat screamed and disappeared into the darkness, replaced by another one. He heard the sound of gnawing flesh and bones. This made his skin crawl, but he felt extremely excited. "Brother Lin?" Jiang Ming asked from behind. He heard Wang Qinian's words and the leg-weakening squeaks in front of him, but he hadn't seen Lin Chuan's movements for a long time, which made him a little anxious. "You go back first and leave the tools, walkie-talkie and pistol to me." Lin Chuan said. "Brother Lin, what are you going to do?" Jiang Ming asked. "Revenge." Lin Chuan said slowly. He seemed to see the people who fell in the fortifications, seemed to see Li Mingfeng's wife and son, and seemed to see his own father and mother. The mouth of the river is close to the Yangtze River, can they be spared? The crowbar in his hand struck again, and the rats became chaotic again. Another mutant rat came in again. "Brother Lin! Come with me!" Jiang Ming climbed up and pulled him hard, but he ignored him at all. "Zhizhi!" Another scream. Lin Chuan actually laughed. "Brother Lin!" Jiang Ming shouted loudly."Kill them all, and the ventilation here will be restored." Lin Chuan said quietly. "I can't kill them all!" Jiang Ming said eagerly. The flashlight was placed in front of Lin Chuan's body. Through the gap exposed by Lin Chuan's body, he also saw the dense red eyes behind the fan. "Come on! If you are here, it will only make them gather more and more!" He finally thought of a reason. But Lin Chuan still didn¡¯t listen to him. "Wang Qinian?" Lin Chuan picked up the walkie-talkie and asked. "Are you here?" "I'm here and I'm installing the exhaust fan. Why don't you come out?" Wang Qinian's voice said anxiously. "What's going on down there? How many exhaust fans are there that can provide normal ventilation?" "Two" Wang Qinian said dully. "How is the air?" "It's worse than before. Some people have fainted." "Are Lao Zhang and Lao Ma here?" Lin Chuan asked. "We are here." Zhang Guohui and Ma Guoming's voices replied. "The nearby residents are all here, so these rats have also followed." Lin Chuan said. "I've been thinking about Zeng Yu's question just now. Will these rats leave after dawn? These pipes are where they hide. What if they don't leave?" he asked. "Even if they leave, they will still come back tomorrow night." "But" The voice was replaced by Leslie Cheung's voice. "Remember the friend who came to me during the day? He was from the military. He told me that the strongest desire of these monsters is appetite. They will try their best to find us and eat us! But as long as we kill these rats, other rats will They will eat their corpses. As long as they kill enough and let the others eat, they will leave." There was silence for a while, and Zhang Guohui's voice asked: "What do you want to say?" "They are stuck now. Each passage cannot harm us, but we can kill them," Lin Chuan said. "You don't need a gun, just long enough iron rods and steel bars. I have stabbed three of them to death. It is very simple and not dangerous, as long as you are not afraid." "Kill them all, and the ventilation duct will be restored. Kill them all. With them, we can have a peaceful sleep tomorrow night." Lin Chuan asked. "What do you say?" The crowbar in his hand thrust out again, but the mutant rat dodged and bit the sharp tip with his teeth. He thrust hard again, and the mutant rat screamed and disappeared into the darkness, becoming food for other mutant rats. "The fourth one." He said calmly. "Look, it's that simple." "I'll do it!" Zeng Yu's voice suddenly said over the intercom. "I'm not afraid. The more people are not afraid of death, the less likely they will die!" Lin Chuan laughed. The screams of mutant rats began to sound everywhere. More and more people plucked up the courage to find iron rods, iron forks and various other items from the tools, and slowly walked towards them. When Lin Chuan killed the thirtieth mutant rat, Chen Jian replaced him. He crawled out of the ventilation duct tiredly and almost fell down from the ventilation duct. "Brother Lin, I killed fifteen!" Zeng Yu said loudly. "Good job." Lin Chuan said with a smile. Someone reinstalled the exhaust fan and connected the power supply after he came out. A faint stream of fresh air began to carry the smell of mutated rat corpses into this underground space that was in desperate need of air. "The exhaust fan started to rotate, and they didn't come in again." Chen Jian's voice came from the intercom. "You keep watching for another half an hour, and then someone else comes in." Lin Chuan said. ¡°Beside the two protective doors, a group of men were loudly cheering for themselves, and through the cracks in the doors, they assassinated those mutated rats that dared to appear at the door. The banging on the door stopped completely. "We have killed at least a thousand mutant rats!" Zhang Guohui came over and said, he himself also killed twelve, which he still can't believe. Lin Chuan smiled and nodded, trying to cheer up, but his foot suddenly slipped and he fainted on the ground.
