The piercing sound was drowned out by the torrential rain. The factory, abandoned for over half a year, naturally had no power. A few beams of light from flashlights shone through the gaps in the door. Yu Xing's arrival was noticed by several people not far from the door, who all stopped talking and turned to look at him.,Hao the assistant clapped his hands and praised: "It's a good habit to collect information before work, no matter what, this habit should be continued in the future.","Later, I'll give each of you a portable camera. Turn on the recording function and for the next four hours, you will be moving around various areas of the factory with your cameras. You can only stop recording to use the restroom. After four hours, if you haven't left the factory and your recording hasn't been interrupted for more than five minutes, you pass."。
