I'm Doing Business in the Underworld

Everything in the universe has its own rules for survival... So where should the soul go after death? Is the legendary underworld a higher-dimensional space? After Bai Ling died, she did not want to be reincarnated. In order to stay in the underworld, she made a series of "efforts" she thought. After she slowly settled down, she started a career with her little master Zizhen... During this period, she encountered a lot of things and slowly made several close friends. The King of Hell, Yeze, was aloof and indifferent by nature. He had been in charge of the underworld for 900 years and was feared and respected by all the ghosts. He once thought that his life would be spent like this. It wasn't until he met Bai Ling that he discovered that he also had emotions... One seemingly ordinary thing involves them in a conspiracy, and whether they can escape from this conspiracy...
