Rule the Three Realms, with the Underworld as the Foundation

The underworld and the heaven had been fighting each other for tens of thousands of years. During a bath, Chen Yan drowned while sitting in the bathtub. After arriving in the underworld, he discovered that the king of hell had pulled the wrong person.

If he disobeys it, Chen Yan's evil power will dissipate and he will be wiped out. In desperation, he disguised his identity and entered the heaven...
