The Bamboo Rat Rings The Bell

No one knew how long the black river was in the Forest of Death nor did anyone know where it started and ended.

Nonetheless, the bamboo rats in the forest knew. The little bamboo rat would lie on a leaf and travel along the black river once in every century. It would look at the beautiful scenery along the way to get rid of the loneliness and depression in its heart.

The river was winding like a giant black dragon.

At the end of the black river stood an ancient tower that had been sealed by dust.
