When the Holy Land of Xiruan was attacked by three old demons, the Holy Lord fell, and his disciples were defeated miserably, Tang Cheng, a handyman who had been sweeping the floor for ten years, stepped forward and showed off his demigod power to kill the powerful enemy. In order to find out the truth about his master's death and rescue his imprisoned mother, he took his senior sister Yunli down the mountain, subdued the monsters Junmo and Xuepo, put down the family's internal strife, broke into the imperial capital, and fought against powerful enemies. After going through many hardships, Tang Cheng learned that the mainland would face the catastrophe of eternal night. He broke through the divine realm and resisted the sanctions of the Wordless Book. In the end, Jun Mo, who sacrificed his life for the resurrection, resolutely broke into the Abi Dao purgatory in the underworld and started a new adventure.
