When Chu Qiu, an ordinary working young man, returned to his hometown to clean the yard, his mobile phone accidentally fell into the Longjing lock handed down from his ancestors. He went down the well to look for an opportunity, and discovered that there were really dragon bones at the bottom of the well. He also accidentally obtained a dragon inner elixir. After the blood fusion, he awakened the special abilities of water control, super physical strength, and underwater survival. After washing the marrow, his body completely transformed. Chu Xiahe tested the water and easily caught a large number of wild crabs and giant snakehead fish. He and his uncle went to the fish market to sell them, and were bought by the five-star heroine hotel owner Su Qingya at a high price. Su Qingya urgently needed rare aquatic products to support important real estate bosses' banquets, and took the initiative to contact Chu for long-term supply.
