Ruoli received a mysterious gift from his brother Ruoji - a seriously injured little fox from across the ocean. Ruoli loves it very much and takes good care of it every day, but he did not expect that when the little fox healed his wounds turned into a man. It turns out that the little fox's name is "Bai Ye" and it is a demon who practiced in the immortal class. Before the ceremony of becoming immortal, he was washed away by his master Fox Demon King and let him go. True immortality. And if Li is his doom.
