The host faces two major choices: First, break out of the coffin and meet Liu Bei, and the reward will be raw flesh and bones and ten years of Yang life; second, continue to practice in the coffin and guide Liu Bei through dreams, and the reward will be three hundred years of Yin life, the small world in the coffin, and the dream charm.
Liu Sheng decisively chose the latter and decided to help his children and grandchildren grow up by lying down in a coffin.
