Being a Ghost: You Have to Defeat the Ghost King First and Then Beat the System

In my dream, I went to the world of immortality. When I opened my eyes, I brought back the secrets of cultivation. Hahaha, I am going to be prosperous now! Mu De, I didn't pay attention to the dream for too long. I forgot that I was in a car accident and went to the hospital to recuperate. When I came back, I died. I was originally planning to become an immortal, but now I can only become a ghost. Just try your best, these little guys are not enough to look at! No matter how hard you try, the Ghost King won't be that stubborn! Work harder, hell boss, what is that? Stop pretending, let me tell you the truth, this system is only worthy of being a unit of measurement for my strength! What, you don't even have the strength of a system and you dare to pretend to be like me? What, you only brought one system and jumped like this? … There is no other way. There are always idiots who come to me with a system and pretend to be masters, so I can only reluctantly practice with them. Even if you beat him to death, the system will confiscate him!
