Modern-day office worker Lin Changsheng accidentally transmigrates to an alternate ancient world and gains an immortal body. He means to keep a low profile and live in seclusion, but his striking looks and refined manner of speech repeatedly draw him into court intrigues and harem conflicts. With every change of dynasty, villains mistake him for the mastermind behind the scenes, unaware that their schemes end up bringing Lin Changsheng together with one peerless beauty after another: a princess betrays her country for him, a female general lays down her armor for him, and a gifted scholar abandons literature to go into business for him. Forced into “marriage first, love later,” he becomes everyone’s darling amid one farcical mishap after another, while quietly seeing each of his beloved women off at the end of her life. A thousand years of loneliness, loving one woman after another: beneath his goofy exterior lies a deep tenderness and the weight of time.
