Nine Burials and Immortality

My name is Jiang Heng and I have nine scars on my chest. Master said it was a birthmark, but later he was chopped into charcoal by the Nine Heavens Divine Thunder in order to protect me. Before he died, he told me: That was not a scar, but nine doors. Leading to taboos, leading to unknowns, and leading to the only truth. That day, I lit up the first scar, traced back three breaths, and snatched half of my life back from the dead. It was also that day, an ancient existence whispered deep in the restricted area: "The gravekeeper... Is awake." Later I learned that all the unknown and restricted areas in this world were looking for someone with the Nine Burial Ancestral Pattern. Once found, they must be buried. I asked them: Why? No one answered. Then I will ask myself - ask the Lord of the Forbidden Zone, ask the Nine Heavens and Ten Earths, and ask the way of heaven above. In this life, I don't want to become an immortal, I just want to ask "why?"
