Li Yuan, a 21st-century slacker otaku, wakes up to find himself transformed into a rotten stone on a solitary mountain. After lying flat for thousands of years, he is forcibly appointed by the heavenly court as the weakest mountain god. With An Mountain desolate for millennia, demons running rampant everywhere, and failing to fulfill his duties resulting in myriad heavenly tribulations, he is forced onto the job. Unleashing the supreme strategy of "Plant Trees First to Get Rich," he recruits mountain spirits and monsters as free laborers, summons wind and rain, lays down spiritual veins, subjugates demons and subdues fiends, step by step turning the barren mountain into a blessed land, unexpectedly staging a counterattack from a bottom-tier minor deity into the top-traffic mountain god stirring up the six realms!
