Near the end of the Zhenguan era, Emperor Taizong of Tang, Li Shimin, suffers a relapse of an old injury and, consumed by longing for Consort Cao, who died young, lies at death’s door. Unexpectedly, he transmigrates to a modern seaside town in 2025 and is reborn in the body of a thirty-year-old man. He is rescued by Cao Feifei, a young woman who runs a small seafood restaurant. She looks remarkably like Consort Cao did a thousand years ago.
Li Shimin stays by Cao Feifei’s side under the name “Li Mo.” Having known nothing about modern life, he gradually adapts and becomes someone she can rely on. As they spend time together, feelings grow between them, but they repeatedly face pressure from Cao Feifei’s greedy uncle and aunt, threats from the mysterious “Golden Age” conglomerate, and a crisis of trust brought on by Li Shimin’s true identity.
As the truth behind Cao Feifei’s parents’ deaths gradually comes to light, Li Shimin decides to return to his family as “Li Shimin, Second Young Master of the Golden Age Group.” He ventures into the tiger’s den to expose a shocking conspiracy involving illegal sand mining, forced demolition, and murder. A love spanning a thousand years unfolds across two eras, writing a modern tale of protection and revenge.
