The Demon Lord Comes to Earth, His Wife, the Fairy Lord, and His Brothers, the Demon Lord?

Lu Guichen accidentally traveled through time and awakened the bloodline of "Li Xin Yi Nian God and Demon", as well as the Chaos Supreme Treasure Hongmeng Jade and the accompanying innate spiritual treasure the God and Demon Sword. He ascended in ten years and attained the realm of Demon Lord after eight thousand years of enlightenment. He also killed Empress Xihe in the battle between immortals and demons four hundred years ago, becoming the supreme king of the three realms. Sixteen years ago, he sealed his monstrous magic power, lived in seclusion in the mortal world, found a mortal wife, and a sworn brother. But... He never imagined that his wife was the reincarnation of Xihe, the Emperor of the Central Heavenly Court of the Immortal Realm who he had personally killed! And brother, this is the Lord of the Demon Realm—Bai Ze! "My wife is the Queen of the Luanfeng Dynasty. Since she is unwilling to tell me her true identity, I will protect her secretly. If anyone dares to touch her, I will kill him from the Nine Clan, even if he is an Immortal Emperor!" "Although Brother Chen is only a mortal, not everyone can touch Xihe's husband. I still don't believe that the resources of the Central Heavenly Court are not enough to create an Immortal King!" "Not everyone can touch my brother and sister-in-law. If you don't believe it, I'm sorry, the Demon Court army will wait for you!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
