Twenty-one years ago, An Yichen was killed by the person next to him. Liang Yuhan turned his head white overnight and avenged An Yichen. However, even if An Yichen took revenge, An Yichen could not be resurrected. He hid An Yichen's body in an ice room. The body did not rot and remained the same as before.
An Yichen was actually the only son of the King of Hell in the underworld and went to earth to undergo calamity. He returned to the underworld and still had memories of the mortal world. After staying in the underworld for twenty-one days, he was ordered by the Emperor of Heaven to go to the mortal world with Yue Mu, the son of the Moon God, to investigate the reason for the loss of the ghost.
Since An Yi's mortal body was not corrupted, he was specially ordered to return to investigate.
When An Yichen, who had been dead for twenty-one years, appeared in front of Liang Yuhan, there was no fear in his heart, only endless longing and regret.
