I'm Burying Gods in the Wilderness

Heaven and earth are like a big tomb, immortals are the dead in the tomb, and the sun, moon, mountains and rivers are just burial objects. On a dark and snowy night, deep in the Hundred Thousand Burial Mountain, a young man from Huandeng Village, Wen Huan, only had a bright bean fire left in his life lamp. The prophecy said that he would not survive until the age of thirteen. That night, the white people opened the old graves and raised the corpses to surround the village. My grandfather's oil was exhausted and his lamp was dry. In order to save people, he lit half a stone lamp in front of the unknown grave, awakened a wordless book of cause and effect, and signed the first IOU in his life - borrowing a ray of fire from the deceased to pay off a debt in front of him. From then on, he could see the debts of all things: the lives owed by ghosts, the wishes owed by immortals, and even the sky owed a debt that could not be repaid. Others cultivate immortality by relying on spiritual roots and chance; he cultivates immortality by borrowing. Borrowing fire, borrowing force, borrowing the fighting body, establishing the basis with blood, borrowing will be repaid, and the interest will be compounded; it can also collect debts from those high-altitude beings on behalf of the deceased. He originally wanted to survive, pay off his debts, and protect the people around him, but along the way he unearthed a secret that had been buried for eternity: why did the immortal die, why did the grave crack, and why was there no such person in his life register... When all the nine tombs were opened and all the debts were due, Tianwai's debt collector opened the account book, and his name was clearly written on the last page of the book. Wen also smiled, picked up the pen, and dipped it in blood. "I paid back this debt with interest." "After paying it back - can all sentient beings live in vain?"
