I Have Just Become a Demon Master, and Master Hachichi Passed by My Door.

The two worlds of humans and ghosts meet, terror revives in the human world, supernatural events occur frequently, and evil spirits run rampant. Ye Tong accidentally awakened the ghost servant system and obtained the Eye of the Ghost Lord. This eye can see through the level, ability and killing patterns of evil spirits. With this vision, Ye Tong officially entered the ranks of ghost masters. In addition, the system also gave him a ghost servant contract. When the ghost is weak, you can use the ghost servant deed on it to subdue the ghost and become your ghost servant. Just when Ye Tong had just awakened to become a ghost master, a strange woman nearly three meters tall and wearing a white dress passed by his door and cursed him to drain his yang energy. Hachisha-sama? The devil is asking for his life? Ye Tong refused to agree. He opened the Ghost Lord's Eyes, saw through Master Hachiku's conditions for defeat, and beat her for a full five hours. When she was extremely weak, Ye Tong took out the Ghost Servant Deed... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
