Good friends become enemies. In "An Emperor through the ages", Lin and Ben are brothers' friends. However, in a family dispute, Lin was mistakenly thought to be a traitor, which led to Lin being charged with treason. So there was a deep misunderstanding and contradiction between them, which eventually led to the break and hatred between them. The Eternal Emperor tells the story that Lin Yan was betrayed and taken away from the emperor thousands of years ago, and was branded as a traitor. However, he did not give up. After his rebirth, he leveled the ages with a mortal body and made the story of an emperor through the ages.
