[She ascended to a high position with a kind heart, but she had to learn the most cruel lesson in rule in the world]
When Si Yan (the heroine), who died young, first entered the underworld, there was chaos in the underworld. After her reincarnation failed, she accidentally traveled back to the underworld before the riots, and met Cang Qi who lived in the Ghost World Castle.
In order to find out the reason for their failure in reincarnation and find a way to reincarnate, the two ghosts set out on the road to Fengdu City.
But because Si Yan came through time, there is no information about her in Pluto's book of life and death. Therefore, as a gangster in the underworld, she could only stay in the Palace of Hell and work for him, striving for leniency and reincarnation as soon as possible.
While Si Yan was working diligently, she discovered that there seemed to be many bugs in the entire underworld's operating mechanism. Driven by curiosity, she jumped into one game after another that was tailor-made for her. In the process of fixing the error, she felt that the pusher behind it seemed to have no ill intentions towards her. Just when she was about to find out the real controller, she traveled through time again, this time she came to an earlier underworld...
Cang Qi (male protagonist), as a failed experimental subject abandoned by higher civilization, is neither a human nor a ghost. He is outside the rules but goes into dangerous situations again and again. He is Si Yan's strongest assistant.
