Immortal Ascension: Starting as a Wronged Son-in-Law

Twenty-year-old Xu Nian transmigrates into a fantasy world where he has already reached the realm of a land immortal. However, his biological father, the Grand Marquis, forces him to enter his brother's household as a slave. Refusing the marriage with a drawn sword and splitting the Heavenly Gate with a single strike, Xu Nian discovers that the conspiracy behind entering the household is part of a chaotic era ruled by demonic forces. To protect his mother and save the world, Xu Nian brings with him the Nine-Tailed Heavenly Fox, Su Su, and joins forces with the Demon-Slaying Bureau and the General's Mansion to banish demons. From slaying fake immortals to beheading the Demon Emperor, he rules the world in the form of a human fourteen-grade monarch, clearing the demonic forces and reshaping the universe. Finally, accompanied by his beloved, he retires to a secluded life, leaving behind a legendary tale of having one sword capable of opening the heavens.
