Xu Yan travels through time to ancient times and becomes a poor farmer with nothing to his name. Yet by his side are his wife, a female emperor, and her ten sisters, whose identities are shrouded in mystery. To feed the family, he spends their entire fortune buying ore, earning the ridicule of the whole village for being wasteful. Little do they know that, using modern knowledge, he manages to produce colored glass and turns his fortunes around overnight, becoming wealthy enough to shake the capital. From then on, Xu Yan opens workshops, creates repeating crossbows, and presents canned goods to the court, changing the fate of the nation with his own hands. But the women in his household turn out to be increasingly extraordinary. His wife is actually the reigning female emperor, and each of her ten sisters possesses remarkable abilities. Until one day, they surround him while holding a yellow imperial robe. Xu Yan lets out a long sigh. Stop this nonsense! I just want to farm and make money. You've truly made life miserable for me, Your Majesty!
