Lin Yuan, who returned to his hometown, became a grassroots cadre in Otsuka Town. During a fire prevention patrol in the mountains, he was selected by the mountain spirit, and he embarked on an alternative path to immortality with "deduction" as the core. Others cultivated to cut off their emotions and desires, but he discovered that the real power came from the land under his feet and the people around him. Repairing canals, fighting floods, fighting spies, replenishing land lines... While dealing with trivial township affairs, he battled wits and courage with Gao Wei's visitors. When the parallel worlds begin to merge and the power of chaos descends, can he hold on to this worldly fireworks? This is a story about taking root and protecting - cultivating immortality is not in the mountains, but in serving the people every day.
