Around five o'clock in the morning, before dawn, the eastern mountains of Yin Country stood under the shadowy night, like a giant black python, winding and undulating. In an open valley, however, it was brightly lit, searchlights sweeping in all directions. Through the lights, countless patrols and tents could be seen, the tents neatly aligned, with a few bonfires in the middle, surrounded by fully armed people grilling food and chatting.
At this moment, a Chinook medium transport helicopter roared in from the night sky, lights flashing and rotors thundering, breaking the tranquility of the valley. However, the people inside the valley seemed unaware, unmoved, with only a few officer-like figures emerging from tents and heading towards the landing grass, where several transport helicopters were parked.
