Wang Buyun, Wang Xianyun, and Wang Shuiyun: three brothers, three different paths. One joined the Black Flag Army to fight the French, selling the Wang family's sugar across the mountains of the southwest even as he battled. One surrendered to the Qing army and went to Taiwan to put down roots, growing sugarcane and making sugar until the strait became a trade route. One stayed behind at the family's sugar workshop in Guanyang, keeping the whole clan afloat with a single pot.
Wang Dexiu and Wang Huaixiu were said to be twins, but one was of the Wang family bloodline, while the other was an orphaned descendant of Shi Dakai, the Wing King of the Taiping Heavenly Kingdom. This secret was like a bomb buried underground, liable to shatter the whole family at any moment.
When the flames of the Sino-French War spread to Taiwan, and news arrived that Taiwan had been ceded after the Yiwei War, the three brothers' fates reached their end. Yet the sugar in that pot kept boiling.
The brothers' lives diverge and converge, and the twins grow up with a secret between them. How can a single sugar workshop put down roots in every direction amid the turmoil of an age?
