Gu Feng was a reincarnated beauty. Before Xiao Gong was reborn, he was a demon lord. Before Xiao Shou was reborn, he was a lotus spirit (small in appearance and looked like a teenager). Xiao Shou wanted to prepare a birthday gift for Xiao Gong, so he used his own life lotus seed to exchange for something that could help Xiao Gong improve his strength. However, all of this was a conspiracy planned by a concubine of the Demon Lord and the son of the Heavenly Emperor (who had taken a fancy to Little Shou). Because Little Shou favored the harem alone, he was hated. Little Shou's actions were revealed to Little Attack. Little Attack thought that Little Shou had betrayed him, so he threw Little Shou into a flaming abyss in Hell. The flames there were extremely domineering and could burn souls. A thousand years later (or ten thousand years?) Once, by chance, Xiao Gong overheard the conversation between his concubine and the son of the Heavenly Emperor. When he learned the truth of that year, he instantly went crazy and destroyed his Demon Palace. Not a single one of the 3,000 harem members survived. Little Offense had obtained the Natal Lotus Seed that Little Shou had left behind from one of his subordinates (one of the Four Divine Beasts). With this as a lure, he had committed suicide and reincarnated to find Little Shou. The Four Divine Beasts had been affected by Xiao Xun's self-destruction and had followed their master into reincarnation. After his reincarnation, Xiao Gong was reborn as a human and had a twin brother. Xiao Gong was not as talented in martial arts as his brother. Later on, he was used as a chess piece by his mother to replace his brother and was hunted down. During the chase, he fell off a cliff and found Little Shou's reincarnation (the prince of the mermaid royal family). At this moment, Lil Shou was still an egg and was escaping with a granny. After Xiao Gong arrived, the granny asked Xiao Gong to take care of the egg (Little Shou) on her behalf because she was about to die. She also used her martial arts (or magic power?) He passed it to Little Offense, giving him the ability to protect Little Shou. Later, Xiao Gong took care of Xiao Shou alone until Xiao Shou hatched. Only then did the two leave the bottom of the cliff.
