It was a sunny afternoon in late autumn, with not a cloud in the sky. The Obunor Forest, near the eastern border of the Donghuang Empire, stretched for thousands of miles across the eastern continent. It was said that the legendary General Duke Obunor had chosen this place to fight the Donghuang Imperial Army to the death. Using the impassable forest as a defensive line and the western canyon as a natural stronghold, he forced the enemy into a trap and buried two hundred thousand Donghuang soldiers. That victory secured the eastern front for the Northern Curtain Federation, and earned Obunor his reputation as a legendary general.
