Xu Mo transmigrated to a xuanhuan world and became a jailer in the Heavenly Prison—his start was nothing short of a disaster.​ The Eldest Princess and her daughter were thrown into the Heavenly Prison, but no one dared to lock them up; everyone kept passing the buck.​ "If you dare not do it, I will!"​ Xu Mo carried one (of them) on his shoulder, held the other under his arm, and tossed them into the prison cell.​ The Ninth Prince of the Dragon King escaped from prison, a terrifying evil monk colluded with a heretical cult,​ An ancestor of a noble clan sacrificed an entire city for eternal life, and a supreme elder of a major sect refined a Dao weapon by slaughtering a million people...​ Starting from the Eldest Princess and her daughter, then to governing a whole kingdom, and eventually to safeguarding an entire realm.​ Xu Mo learned a shocking secret: the royal family was cursed to have no descendants, and the Emperor... was actually my woman?
