In the twelfth year of Chongzhen, there was a severe drought in Huaiqing Mansion. A sweet well that could produce water was more valuable than human life.
When Gu Chuan, a well builder, was digging a well for Zhang Dahu in the west of the city, he encountered an "earth dragon" and was buried three feet deep at the bottom of the well. With his unique ability to listen to soil and distinguish water and his concern for his wife and children, he dug out a glimmer of life from the soil, but he broke his leg and became a cripple.
When Zhang Dahu missed his wages, local ruffian Brother Bao came to collect debts, forcing the Gu family into a desperate situation. Gu Chuan used the broken body as bait and used his lifelong well craftsmanship to set up a trap - he first destroyed the Zhang family's only old well, then forced the wealthy Zhang family to submit with sky-high maintenance fees, and even used the other party's power to deal with Brother Bao.
When he used his homemade "Desilting Dragon" to revitalize the well, everyone thought he was making a lot of money, but they didn't know that he had already laid deeper seeds. This well is not only the driftwood that saved his life, but also the noose around Zhang Dahu's neck. It is also the dignity and justice that a craftsman fights for with his life in troubled times.
