At the end of the Qing Dynasty and the beginning of the Republic of China, the Zhao family suffered a sudden misfortune, and the daughter-in-law behaved abnormally and fell into madness.
Fortune teller He Yang, carrying "The Theory of Yin and Yang of Five Elements", stepped into Zhao's house and tried to uncover the supernatural power behind it.
Aunt Zhao, out of worries about the future, reached an ulterior deal with the yellow landlord, but she didn't know the hidden dangers.
During the investigation, He Yang discovered that Aunt Zhao's daughter-in-law had an accident, which caused the consequences of the separation technique to begin to appear.
As He Yang investigated further, he discovered that the conspiracy hidden in the darkness was far more than that simple.
With every step He Yang takes, family, moral choices and supernatural powers slowly emerge.
But the price was far heavier than he expected.
