Supernatural Insight Eyes - Chapter 37 Master Legend 00

He died on the wedding of the girl he had a crush on, after a long and successful career. After convincing Yama to send him back to the world, he decides to fix the areas in which his life went wrong. Realizing the lack of love and romance in his past life, he sets out to conquer the hearts of various women.

I have calculated for people before I was born, and I have all five yin, and I am born with fierce ghosts. A knowledgeable gentleman said that I will not live to be seven years old. After death, I will cultivate blood-clothed little ghosts to harm people.

In order to save me, my grandmother married me a child-in-law, so that I had an Ann birthday, although I later discovered that the daughter-in-law and sister-in-law are not human…

I have been lingering and panting since I was a child, and I have been accustomed to accepting it, but my grandmother was killed.

For this reason, regardless of karma, I inherited my grandmother’s job of raising ghosts and vowed to send everyone who killed her to hell.
