Qiu Ning's body suddenly shuddered, and a gust of wind blew in the room out of nowhere, and her eyes were fixed on the corpse, not daring to look away.

After a long pause, she felt less afraid, she came to the door again, shouted to the outside with all her might, and hit the iron box next to her with the stone in her hand, she didn't know how many times she had done this action, the place where the iron box had been knocked was obviously sunken inward, but despite this, it still didn't help, the outside was like an empty city that was evolving by air pollution, there was no life, and even some quiet and scary. She didn't know if the woman she had saved was still alive or if the rescue team would come back to search, staring stupidly at the collapsed cabinet next to her. She had never felt so helpless before, perhaps because her previous life was too comfortable, she began to hate why she didn't agree to work in the unit introduced by her father, if it wasn't for sticking to her ideals, maybe she wouldn't be trapped here. She felt a boulder in her heart, and she wanted to cry but couldn't leave a single tear.

Qiu Ning sat by the door with her knees folded against the wall, and by the faint light source outside the stones, she suddenly found that there was a windshield under the ceiling on the side of the room, and she ran under the hood in surprise, although she couldn't reach the hood at all with her height, but this discovery undoubtedly made her suppressed heart suddenly excited. She looked around, dragged the somewhat deformed iron box that had been knocked out of the door under the windshield, and stepped on it carefully, barely reaching the edge of the windshield.

She looked through the gap with her feet crossed, and although the pipe was not wide, it was enough for her body to get into, and it was pitch black inside, and a light breeze was blowing from it, and she was sure that the wind should have been blowing from this ventilation duct. Although there have been many earthquakes, the outer cover is still strong.

Tyunin jumped down from the box and looked around for tools that could be used to unscrew the screws, but after searching for a long time, he couldn't find anything suitable, either because the size didn't match, or it wasn't hard enough. She stood in the middle of the room, glanced at the corpse, and suddenly remembered the keys, so she picked up the key ring that had been left in the corner, and felt that she was instantly full of fighting spirit, even though she knew it would be very difficult.

She stood on the cabinet with her arms crossed, trying over and over the different types of keys, and finally found a key that could barely fit into the groove of the screw, and although she could get in, it was obviously a bit difficult to open the already obviously rusty screw. Even though she is a rock climbing enthusiast, her arms still can't adapt to the long-term lifting, coupled with the psychological pressure of being trapped in the ruins during this time, and the stomach that has not eaten and is raising the flag to "fight", which exacerbates the sore feeling on her arms.

She spun the key vigorously, the screws still didn't move, and her fingers were red marks because of the force, and she put down her arm that was already numb a little discouraged. After a while, with the mentality of trying it out, she used the key to insert the screw hole on the other side......

With the friction sound of "creaking", the screw rotated little by little, Qiu Ning's eyes gradually released brilliance, she slowly screwed the screw, the screw fell off little by little, she wanted to continue to rotate directly with her hand, but the strength of her hand was far less than the friction of the screw in the groove. Although her fingers hurt a little from the key, and although her arms were hanging in the air and were so sore that she couldn't tolerate it, she still didn't give up and continued to persevere, she didn't know if it was worth it or not, she just wanted to try to do what she wanted, which may be the reason why she was able to stick to her dream......

The screw was finally unscrewed, she hung down her arms, and threw the screw on the ground as if relieved, without slackening at all, she pushed the corner of the windshield with the tips of her fingers, and used the screw that had not been unscrewed as a shaft, pushing hard like the other side, with the harsh sound of metal rubbing against the wall, the cover was turned to the other side little by little, and the dark ventilation duct appeared in front of her, she was suddenly full of fighting spirit, and felt that the pipe in front of her was as dazzling as a door to the light. Qiuning looked around the room, and after making sure that nothing could be used only by her, she hung her hand on the edge of the pipe and slipped into the dark passage......

She held her phone up in front of her and crawled in little by little by the faint light on the screen. The passage was covered with dust, the small space was suffocating, she felt a little unbearable, and the dust got into her nose, causing her to sneeze, and she gagged her mouth and nose with the collar of her sweater, and slowly advanced.

Just climbed for a while, suddenly heard what seemed to be a sound in the room just now, she wasn't sure if it was her auditory hallucination, so she stopped, and looked nervously behind her by the light of the mobile phone, from here she couldn't see the room clearly, she could only see the faint light of the pipe mouth, the closed environment in the passage, and the unknown factors around her, so that the fear in her heart was instantly amplified. Qiu Ning's body trembled, and he quickly crawled inside while looking behind in a panic.

Not knowing how far she had climbed, she slowly stopped, lying on her stomach in the pipe and gasping. The mouth of the pipe behind her was barely visible, and she didn't know how long she had been crawling, but she felt exhausted. This way stop and go, and from time to time you have to press the side button of the mobile phone to ensure that the mobile phone is in the state of opening the screen. This distance of whether it is long or short consumes most of her physical strength, and she feels as if her body has been hollowed out, only this skeleton is struggling to support it.

Suddenly, a black shadow appeared in front of her, and with the light of the mobile phone screen, an object resembling a black sphere was getting closer and closer to her, accompanied by a "creaking" sound, and when she could gradually see that it was a mouse, the mouse was close at hand, she dodged backwards in a panic, and pressed her body against the side of the pipe. The rat passed by her on the other side of the pipe, and galloped wildly towards the path from which Tyunin had come, the first time she had ever been in such close contact with a rat, its heart beating rapidly, as if it were about to jump out at the edge of the Adam's apple. She held her breath and kept shining her phone on the mouse, staring at it for a moment, until it disappeared from sight, and then dared to continue crawling deeper.

To the right of the straight pipe, a new path appeared, and Qiuning stopped at the fork in the road, tilted his head and put his phone into the passage on the right, although he could see the near distance through the light, it was still pitch black in the distance. She lay in the pipe and thought for a long time, and finally chose the fork in the road on the right. She twisted her body with some difficulty, turning around the right angle.

As she went deeper and harder, the environment became worse and worse, and the pipes were covered with cobwebs, and she began to regret that she shouldn't have taken this path, but she had no chance to choose again. At this time, I don't know if the phone is out of power, the screen is completely off, she shakes the phone vigorously, but it still doesn't help, and the only beam in the dark is gone.

She was discouraged and lying in the pipe, the environment where she couldn't see her fingers, and the long-suppressed mood made her on the verge of collapse. She frantically smashed the wall of the pipe with her mobile phone, and the deafening sound resounded through the pipe, only hitting her ears because of the tinnitus caused by the excessive sound before stopping. She wanted to turn over, but the small space restricted her from doing so, and because of the rollover, the back of her head hit the top of the pipe, Qiu Ning screamed like crazy, saying those dirty words that she wouldn't say at all in her usual life, venting her emotions angrily, and her echo came from the distance of the pipe, and the endless echo only made her emotions more depressed. With tears in her eyes, she clutched her phone tightly with both hands, feeling all the tears drip on the cuffs of her clothes, she stopped yelling, and turned from anger to silent crying......

She didn't know how long it had been going on, but gradually, she stopped sobbing and realized that she was still in danger. Although the mobile phone is no longer useful, Qiu Ning still holds it in his hand, hoping that maybe the screen will light up after a while......

She fumbled and crawled for a while, feeling a "creaking" sound around her, at first she thought it was another mouse, until the sound got louder and louder, only to realize that it was the sound of friction at the junction of the pipe, when she realized the danger, it was already too late, the pipe began to disconnect a little bit from the place of connection because it could not support her weight, and at this moment, this section of the pipe quickly fell off, smashed the ceiling, forming a slope, Qiuning saw the long-lost ground from the crack, she didn't even have time to grab anything, Along the mouth of the broken pipe, she fell heavily to the ground, and the ground raised a layer of dust, which instantly blurred her eyes, and she gradually lost consciousness in the dusty environment......
