The ancestral porcelain vase inherited by Ye Mumu suddenly connects to the Great Qi Dynasty two thousand years in the past. On the other side are the young general Zhan Chengyin, trapped in a besieged city amid famine and dwindling supplies, and twenty thousand defenders on the brink of death. With a bag of rice, a basket of vegetables, and a box of medicine, Ye Mumu uses modern supplies to shore up the ancient defenses. When she learns that Zhan Chengyin historically died defending his country at just twenty-one, she makes a decision: she will spend her entire multibillion-dollar fortune to rewrite history and keep him alive.
