[Invincible at the beginning] Lin Tianhong traveled to the world of immortals and demons, from a mortal, to struggle for 10,000 years, and became the demon lord of the demon world who terrified the Three Realms. The horror of strength made all beings in the Three Realms tremble. In order to perfect his Dao, he lived in seclusion in Fengjing City of the Shenfeng Dynasty in the Nether Realm and met his wife Li Xiyue. Ordinary life, ordinary self, and a gentle wife make him enjoy this ordinariness very much. He didn't know that his wife was actually the central Heavenly Emperor Xi and Empress of the Immortal Realm who were killed by him, reincarnated in the mortal world, and awakened the immortal consciousness. Both of them didn't know each other's identities, and they both thought they were just ordinary ordinary people. So, the Demon Lord of the Demon Realm and the Central Heavenly Emperor of the Immortal Realm, two sworn enemies, became husband and wife by chance, and started the story of falling in love with each other and having children. "Since my wife wants to live in Fengjing City, whoever dares to disturb the peace of this city and destroy her peaceful life will be killed." The terrifying supreme of the demon world instantly turned into a wife-protecting madman. The world is big, and my wife is the biggest.
