Transformed into Bai Yueguang's Substitute for the Demon Lord Who Died Early

A hundred years ago, the genius swordsman Xie Wenhan died of Bai Yueguang's first love, and became obsessed with it, and became the cruel demon Lord Nether who destroyed the world. A hundred years later, in order to kill the Demon Lord, the Immortal Sect collected dozens of substitutes who looked like the Demon Lord Bai Yueguang, formed a harem group, and sent them to the Demon Palace with the intention of poisoning the Demon Lord in his bed. As soon as Jiang Sui opened his eyes, he transformed into one of the members of Bai Yueguang's harem group. Demon Lord Netherworld has an unstable personality and ruthless methods. He is a super devil who kills people without blinking an eye. Jiang Sui didn't want to die, so he formed a team and ran away overnight. As a result, I met the Demon King by chance in the middle of the night and watched with my own eyes as he burned two Bai Yueguang stand-ins to death without hesitation. Seeing that it was his turn, Jiang Sui closed his eyes, admitted that he was unlucky, and prepared to die heroically. When he opened his eyes again, Jiang Sui was taken back to the Demon Palace by the Demon Lord and fed him delicious food. People around her said that Jiang Sui was the reincarnation of Demon Lord Bai Yueguang's soul, and the first love that Demon Lord had been searching for for hundreds of years. But only Jiang Sui knew that, not at all. The Demon Lord once sneered in front of him: "Love? Is he worthy of being a substitute?" One night, Jiang Sui met his original master in his dream. The master was ruthless: "You have been planted with the seven-day lover's poison. If you don't have sex with the Demon Lord within seven days, and the poisonous insect is transferred into the Demon Lord's body, you will die." Jiang Sui: I feel numb. Jiang Sui, who was lying down and ready to eat and wait for death, opened the door and was carried onto the bed by the Demon Lord who was walking towards him. Looking at Demon Lord's hand untying his belt, Jiang Sui reminded me thoughtfully: "I am poisonous, and whoever touches me will die." The ruthless, cruel and ferocious Demon Lord grabbed his chin: "Really, then I would like to give it a try." Intention: perseverance, cultivating immortality to survive.
