In his previous life, Ye Yunfan was the greatest genius in the Immortal Realm. After being jointly attacked by thirty-six Immortal Emperors, he was forced to destroy his physical body and reincarnate. Upon returning, he finds himself in the lower realm as a useless live-in son-in-law with a crippled dantian who has been poisoned. When the Seven-Colored Divine Lotus within him awakens, he inherits a mysterious man's legacy, the Book of Time and Space, and awakens a Time and Space Martial Soul. From then on, he rises from a crippled nobody, crushes the Zhang family, slays three rising prodigies, and marries a stunning beauty before entering the Wuji Academy. But just as his divine powers reach their peak, he discovers that the masterminds behind everything are Immortal Emperors from the Immortal Realm conspiring with the lower realm's assassin organization, Hell Gate. Together, they have laid out a nine-level underground palace sacrificial formation, seeking to seize his wife Mu Feiyao's Twin Phoenix Physique. His beloved is kidnapped, his brothers are bullied, and his former enemies sit high upon the Immortal Palace...
