At night…
Deep in the Wu Mountains, in the Hidden Dragon Cave…
The Hidden Dragon Cave was a naturally formed karst cave. The entrance was more than 30 meters tall, and the cave was 10 kilometers long. It meandered like a coiling dragon and was named Hidden Dragon by the Prince of Wu.
The Prince of Wu had only secretly developed the Hidden Dragon Cave in recent years. The area within a radius of dozens of kilometers was full of dense forests that humans rarely visited, and tigers and leopards roamed freely in the forests. Even herb pickers who went into the mountains to collect herbs rarely set foot in this place.
In the middle of the night, the outside of the Hidden Dragon Cave was as dark and silent as usual. But 250 meters into the depths of the karst cave, one could see a wall built of mountain stone. There were nearly a hundred elite soldiers in excellent armor inside, leaning against the wall and resting silently.
