The Liu family has made a living by making coffins since ancient times. According to legend, their ancestor was a carpenter in Penglai. During the Qin Dynasty, he stole fairy wood and built an incorruptible coffin. If this thing appears once and for all, it will disappear, and it can only be found in unofficial history and folk records. Later generations have been searching for it for more than two thousand years. The father of Liu Coffin, the heir of the Liu family, suddenly and mysteriously disappeared. He was kidnapped by "four businessmen" and forced to search for the incorruptible coffin.
