Thousands of years ago, there was an earth-shattering battle between Jiyin Mountain and Yin Si. In the battle, Jiyin Mountain was defeated miserably. The Wuji Ghost King was framed by King Qin Guang's conspiracy during the battle. He was seriously injured and fell into the realm of animals. After thousands of reincarnations, he had the chance to be reincarnated as an adult again. Cui Fujun, who became friends with the Ghost King during the war, was also brutally murdered.
Thousands of years later, Cui Fujun returned to the underworld and became a god again, but the Ghost King never reincarnated as an adult. Everyone thought that his soul had been annihilated in thousands of reincarnations and that there would be no chance of rising again. However, exactly two thousand years later, someone actually inherited the name of Wuji. Yes, it was indeed the Ghost King.
But the memory of the Ghost King has long been washed away in thousands of reincarnations. How can he obtain the memories of the past, and how can he return to his once proud throne in the Age of Ending Law? The appearance of a book changed him. There is a limerick in the book, which suggests that the treasure contains clues to seeking immortality, but also emphasizes that asking questions will only lead to nothing.
Wu Ji embarked on a journey to collect various treasures, and since then he has entered a whole new world. The skinless cat demon, the ten thousand year dragon spirit, the nine-tailed demon fox, the inner elixir of the drought demon, the Yinglong scale cluster, the unicorn demon blood... Each piece of spiritual treasure, each weird story, is behind it a conspiracy or the return of the ghost king, and Wu Ji will witness it together.
