In the meantime, the ghost of Su-yitong appears in the form of a lantern, which he uses to summon the dead body of the corpse. The ghost tells Su-Yitong that he is not dead yet, but that the corpse is still alive. He explains that the butterfly poison he is using is fatal, and that after an infection, the butterflies will fly out and infect the body. He names the poison "phantom butterfly poison" and asks the ghosts to help him.
