During the Warring States Period, Yuan Xizhi, the son of a very famous writer, ran away from home, so he went to a barren mountain with his servants. However, he got lost on the mountain. Yuan Xizhi, who was extremely hungry, saw an injured little fox. Yuan Xizhi, who had no compassion, ate the little fox. Therefore, the wronged little fox came to modern times to seek revenge on Yuan Xizhi's descendants.
