Soul-Hunting, My Cultivation Level Skyrocketed After Solving the Case.

When criminal policeman Yang Yu was investigating a serial throat-slitting case, he was set up by the real murderer to cause a car accident. On the verge of death, he traveled to an imaginary world called "Northern Zhou Dynasty" and became a bodyguard with mediocre martial arts. There is a dog with black fur next to him who can communicate with his mind. His name is Fu Dou. Only by finding nine ancient artifacts that can be combined into one to open the Heavenly Gate, Yang Yu can return to reality and catch the real culprit in the singing case. In order to return to reality, Yang Yu embarked on the road to find weapons. Behind each artifact was a bizarre murder case. He had to return to his old career and use modern criminal investigation knowledge to solve ancient unsolved cases.
