Ye Zhao, burdened with a million in debt, accidentally discovers that the abandoned well in her ancestral home leads to a world plagued by natural disasters. Half a bottle of water saves thirty thousand disaster victims, and a bag of grain trades for millennia-old gold and jade. Relying on modern supplies, she feeds a dead city, slaps scumbag men in the face, reverses a troubled era, and also makes the cold-faced defending general Pei Yanchuan fall in love with her. When the imperial court and powerful enemies approach, what they have to save is no longer just a city.
