In the deep mountains and forests of Northeast China, the Japanese once sent a survey team.
They discovered a large cave in the old forest that led deep underground.
In order to save the villagers who were used as laborers, Yu Zhilong launched a long-term war of resistance against the Japanese alone in the mountains and forests!
The Japanese ordered workers to dig into the mountains and forests, hoping to carve out a road that could accommodate vehicles and semi-permanent fortifications for defense.
Something went wrong while the Japs were exploring underground caves. A large number of Japs soldiers were carried out of the caves, and then died in mysterious circumstances one after another!
When Yu Zhilong killed two Japanese soldiers and took their guns, revenge began!
Why do so many mysterious deaths occur among Japanese soldiers?
What kind of strange power lies deep in the cave?
Why are the water supply troops here?
While taking revenge, Yu Zhilong also wanted to find out the secrets hidden deep in the cave!
