Xie Xiaoman, the abandoned son of the uncle, was burdened with a blood feud and the secret knowledge of "Tiangong". He walked out of the uncle's house and opened a "purifying bathhouse" in the slums in the south of the city: five cents, hot water, everyone can afford it. In order to replace his mother Zhaoxue and eradicate the shadow organization "Zhulong", he started from a public bathhouse, dealing with the powerful and leveraging their strength. Show off your miraculous skills, prove the injustice, and kill the culprit, every step of the way is startling. When the dust settled, he rejected the glory of the capital and went to the countryside in the south of the Yangtze River with his friends and companions. With the ambition of "purifying the world", he devoted himself to water conservancy and agriculture, and turned what he had learned throughout his life into real skills that benefited the people. Since then, the temple has lost a chess piece, and the people have gained a real craftsman.
