After her parents die, Ye Mumu discovers that her family's ancestral vase has gained a spirit and can connect to the ancient world two thousand years in the past. Through it, she meets Zhan Chengyin, a young general from ancient times who guards the strategically important border city of Ningguan as its marquis. With nowhere else to turn, Zhan Chengyin prays to the deity Ye Mumu for water and food. Ye Mumu readily grants his wish! She stockpiles vast quantities of supplies to feed the soldiers and civilians, giving the people of ancient times a taste of modern American-style wonders.
