After the time traveler Qin Feng became the deposed prince, he was sent to guard the imperial mausoleum but was accidentally bound to the "god-level sign-in system". In the isolated imperial mausoleum, he checked in at secret places such as the Sword Burial Valley and the Library Pavilion, and encountered rare opportunities such as the peerless divine body and the Immortal-killing Sword, silently accumulating strength for thousands of years. When the evil spirits invaded the imperial city and the dynasty was on the verge of destruction, in despair, a shocking sword cry came from the imperial mausoleum. Qin Feng emerged from the sky with an invincible appearance and turned the world around alone.
