Under the night sky, in the vast valley, the enormous construction complex was brightly lit inside, yet pitch-black outside, with the usual floodlights nowhere to be seen. Suddenly, the rotor blades of a helicopter began to spin, and lights inside the cabin turned on, revealing a man and a woman, Luo Zheng and Lan Xue, excitedly operating the control panel.

They could only point and gesture at the door, and did not charge forward. A while later, a few people dashed over in panic, but it was already too late.
