Zhou Huaian, a direct-graduate transfer student from Qingtan University, was assigned to the municipal government office because of being squeezed out by villains. He thought that being transferred back to the municipal party committee office would be a turning point, but he was suddenly "assigned" to a temporary job in Linze Town. The poor town is short of water and petitions dominate the list. The villain Chen Mochuan is mediocre and inactive. Chen Yubai seizes the opportunity to occupy the ancient river to build a factory. After rescuing the 1958 water conservancy manuscript of his mentor He Beichen at the fire scene, Zhou Huaian discovered the key to the activation of ancient river channels - using the theory of his doctoral thesis "Ancient River Channel Governance" + historical hydrological data to design water diversion plans, outsmart land-occupying bullies, and awaken sleeping ancient river channels. From being questioned as a "nerd" to delivering banners to thousands of people, he empowered the grassroots with academics and turned poor towns into "gold mines". He also worked step by step in the secret war of officialdom, vowing to make the rebirth of ancient rivers become the starting point for rewriting Linze's destiny!
