Chu Wentian was stolen away by Demon Emperor Ye Kuangge when he was a child, and his ghost was removed and he lost his memory.
After his soul returned to its original place, Chu Wentian tried to escape from the Demon Realm but was intercepted by Ye Kuangge, who captured him and threw him into Purgatory.
In Purgatory, he went through endless hardships. In the end, in order to survive, he actually integrated the magic, martial arts, Buddhism and swordsmanship into one body, becoming the first person to leave Purgatory alive.
After escaping from the Demon Realm, his revenge on Ye Kuangge also officially began. It was not until he defeated Ye Kuangge that he discovered that all of this was a game carefully arranged for him.
