My Wife and I Dominate the Three Realms

[Invincible Start] Lin Tianhong traveled to the world of immortals and demons. From a mortal, he struggled for 10,000 years and became the demon lord of the demon world who frightened the three worlds. The terrifying strength makes all living beings in the three realms tremble. In order to perfect his Tao, he went down to live in seclusion in Fengjing City of Shenfeng Dynasty, where he met his wife Li Xiyue. An ordinary life, an ordinary self, and a gentle wife made him enjoy this kind of ordinaryness. Little did he know that his wife was actually the Central Heavenly Emperor Xi and the Empress of the Immortal Realm whom he killed, who descended to earth and reincarnated, and awakened her immortal consciousness. Neither of them knew the other's identity, and both thought they were just ordinary people. Thus, the two mortal enemies, the Demon Lord of the Demon Realm and the Central Heavenly Emperor of the Immortal Realm, became husband and wife by chance, and began a story of falling in love and having children. "Since my wife wants to live in Fengjing City, anyone who dares to disturb the peace of this city and destroy her peaceful life will be killed." The terrifying Demon World Supreme instantly transformed into a wife-protecting madman. The world is big, but my wife is the biggest. "Whoever dares to harm my husband will be ordered by this emperor to exterminate his clan." The domineering Central Heavenly Emperor also turned into a husband-protecting demon. Anyone who offends my husband will be punished no matter how far away he is.
