Chen Feng, an antique dealer, transmigrates to the Great Tang and becomes Li Ke, a prince carrying the bloodline of the previous Sui dynasty. Caught in the whirlpool of imperial power and an identity crisis, he activates the jade pendant he carries, which contains a 100,000-square-meter stasis space where he can store things and grow crops. To survive and live freely, Li Ke settles on a strategy of keeping a low profile while building up his strength. He leverages the power of Crown Prince Li Chengqian and Emperor Li Shimin, studies under Qin Qiong and Li Jing, and secretly accumulates wealth, technology, and talent. He offers plans to deal with disasters, then deftly lets others take the credit. He establishes the commercial empire of Jade Towers and Magnificent Palaces, amassing a fortune, and uses Shu as his base to secretly build a navy for the future. As the Great Tang's golden age dawns, Li Ke has already set his sights overseas. In the fifteenth year of the Zhenguan era, he personally leads a fleet east to conquer Wa. Sweeping all before him, he incorporates it into the Great Tang's territory and establishes the Eastern Sea Protectorate. He relocates its people and assimilates them, burns their histories and changes their customs, ultimately becoming a carefree prince across ten thousand miles of sea. With the jade pendant at his side and his space still intact, freedom and ease are the true way home.
