The ancient time was shining and the world was independent. Xuan Jin was originally a lonely soul in the ruins, but he found a "Remembrance Stone" among the vast ruins and glimpsed the afterimage of the lost divine dynasty. The path to immortality is not about cultivation, but about seeking the truth that has been sealed away in the dust. When Xuan Jin walked on the ancient road of Youguan, he saw everything that had been forgotten - the broken heavenly book, the sleeping mythical beasts, and the disappearing ethnic groups. He used the Remembrance Stone as a guide to restore the traces of ancient civilization, but gradually realized that his lifeline was actually connected to the lost divine dynasty - with each piece of history he uncovered, his soul was eroded. Xuan Jin struggled between the truth and survival, and finally realized that only by letting all living beings remember the past can he not be forgotten. This article uses "memory" as its soul to reshape the realm of immortals and tell a magnificent epic about the struggle against forgetfulness.
