Sword Kingdom Shenwu

The protagonist, Jin Tailang, was originally the supreme sword god in the immortal world. Due to a sudden attack by his mortal enemy, the Sword Demon, he was forced to be reborn and reincarnated as a down-and-out prince of the human empire. Why down and out? Because Jin Tailang was personally judged by his father to have extremely poor talent in swordsmanship and would only be an inferior swordsman in the future, he had been ostracized and ridiculed by the royal family officials since he was a child. The daily food, clothing and supplies of the palace were scarce. He had no choice but to pretend to be a playboy who was bohemian, engaged in eating, drinking, whoring and gambling, but secretly he practiced swordsmanship and slayed demons. He established prestige and accumulated power. He vowed to make a comeback, return to the fairy world, and become the supreme sword god again...
