In his past life, Lu Chen died miserably as a "workhorse" used by the system to block disasters for Lin Qingyu. After being reborn, he proactively transferred the system to Lin Qingyu, seized all opportunities first, and his cultivation surpassed him. In the sect grand competition, he defeated his enemy in three moves; in Qingniu Town, he exposed Lin Qingyu's collusion with the Demonic Sect but was instead framed. In the war of the two realms, the two simultaneously awakened the memories of their past lives as the Immortal Emperor and Demonic Emperor, and the system core Xuanji—the fragmented soul of Lu Chen's past-life Dao companion—burned her true spirit and dissipated. Lu Chen reversed space-time to return to Earth, married his beloved Lin Xiaowei and had a daughter, sealed his immortal power, and returned to ordinary mortal life.
