Lin Xuan transmigrated overnight into the Heir of Prince Qin. From the start, he was a notorious playboy in the capital, well-versed in drinking, gambling, and brothels, and everyone laughed at him as mud that couldn't support a wall. Yet no one knew an unfathomable soul was hidden within this body, and even Xiao Qing, the seemingly delicate maid by his side, turned out to be a hidden level nine Dharma-form grandmaster. He originally wanted to muddle through life as a peaceful prince, but an imperial decree betrothed the iceberg sword immortal Su Qinghan to him. She practiced the Supreme Forgetting Love Sword Canon, was afflicted with the Demon Clan's Abyss Snake Seal, and her life hung by a thread. Lin Xuan wanted to refuse the marriage, but ultimately couldn't abandon this life. Thus, the profligate heir put aside his laziness, step by step stirring the winds and clouds of the capital, defying the heavens to change his destiny, and winning back the sword immortal.
