Shitian's real name is Xiao Wen. He is the reincarnation of a holy demon spirit son who comes out every ten thousand years, and is born with the dual holy bodies of Buddha and demon. Buddha Pu Cihang accepted him as his disciple. Because of his dual cultivation of Buddhism and Demon, he was both good and evil, and his mind was defiant and arrogant, which made him even more wild and unruly. Thousands of years ago, he fell in love with Immortal Emperor Fengqin Fairy Shuyu. The two fell in love with each other. They often played the harp and harp in front of the flowers in Yaochi Fairy Mountain under the moonlight, and made a long-cherished wish to stay together for a hundred reincarnations. However, the late emperor refused and imprisoned Shuyu in Langhuantai of Lingxiao Mountain. Xiao Wen learned that after weeping blood for forty-nine days, he destroyed his eyes and offered a blood sacrifice to the underworld. Shura became a demon since then. Called the Demon King of Darkness and Light, he changed his name to Killing Heaven. . . .
