Su Wantang was a water conservancy engineer in his previous life and was pushed into a flood gate by his colleagues. After waking up, she became a six-year-old girl in the disaster year. There was a severe drought in the village for three months, but my grandmother dragged my mother to death and called her and her brother money-losers. Su Wantang knelt in front of the soul and heard the sound of water coming from the bottom of the well. She discovers a portable divine well that can produce clean water, store supplies, and warn of floods. That night, she put all the Su family's grain, money, and water bags into the well, and took her younger brother to escape from the drought-stricken village. While others fight for a mouthful of water, she can identify water veins, avoid flood peaks, and rescue victims. But hidden in my mother's belongings is half a river defense map, pointing to my father who has been missing for many years. She thought her father was a fugitive, but later she found out that he was a flood control officer who was unjustly imprisoned.
