Driven to desperation, he entered Changbai Mountain alone. Suddenly, the jade pendant on his neck became scalding hot, awakening his ability to understand the inner voices of animals. With a kind heart, Lu Li successively rescued beasts in the mountains and gained their assistance, smoothly gathering many rare medicinal herbs to save his mother and improve his family's livelihood, and became engaged to his childhood sweetheart Su Xiaoman. Filled with jealousy, Lu Kui and his son entered the mountain to plot against Lu Li, all of which were resolved by Lu Li one by one. Once, while exploring a deep mountain ancient temple, Lu Li discovered that the jade pendant was the token of the mountain god.
