Bai Qingyi, according to legend, was a terrifying man who lived through three reincarnations and was the founder of Netherworld Valley. Because he gave all the evil people in this world a place to live, he was surrendered by all ghosts.
The Valley of the Netherworld is located under the Netherworld Water. It is a place where there is no sunlight all year round, and you cannot see your fingers when you reach out. It is a place of extreme cold, darkness and suffering.
There was a battle between good and evil, and someone rebelled in the Netherworld Valley. Bai Qingyi was unable to defeat the evil, and was forced into this ghostly place where life was worse than death.
And the most important thing is that he lost a treasure that will make him regret for the rest of his life...
