His name is Coffin Born, he comes from the coffin and goes to the coffin. In the troubled times of the Republic of China, millions of people died in vain, the underworld was unable to collect the souls, and the boundary between yin and yang collapsed. Fan Coffin, the seventh-generation descendant of Fan Ji Coffin Shop, feeds nails with blood and holds coffins with souls. He travels to the ancient Yellow River Road, Huai'an tombs, and Zhima Yinsi. Debts of seven generations, a marriage contract spanning a hundred years, and a growing blood coffin. When he finally stood in front of the reincarnation disk, he discovered that the coffin man himself was the biggest trick. "The descendants of the Fan family are neither humans nor ghosts. They were born in coffins and died in coffins."
