After Lin Wuya, a modern doctor, died unexpectedly, he found himself transformed into Sha Wujing, who was demoted to heaven. After being bound to the "Three Realms Causality Correction System", he can rewrite the fate of the original characters by completing designated actions. In order to break the inevitable death ending of the monk Sha Monk in the book, he used the system to transform all the disasters suffered by Sun Wukong on his way to seek scriptures into his own cultivation. He exposed the conspiracy between the Jade Emperor and the Tathagata in public at the Lingxiao Palace, and finally restarted the closed causal loop of Journey to the West with his flesh and blood.
