Lu Ming, a modern water conservancy engineer, accidentally fell into the water while surveying a canal. His soul traveled back to the late Warring States period and became a minor official under the Chunshen Lord Huang Xie's family. With the help of modern knowledge, he participated in the feat of "establishing Wuxi Pond and regulating Wuxi Lake" by the ancient Furong Lake, but found that he was destined to die in history - historical books record that Chun Shenjun was eventually killed by Li Yuan. He was reborn again and again (returning to key points after each death), and experienced historical scenes such as Fu Chai's banquet with ministers, Wen Tianxiang's night berth, and Kangxi's southern tour. He finally understood that what is locked on this "Tianguan" island is not Feng Shui, but the obsession of countless people to protect this land and water.
