Zeng Xiaoyu is a medicinal herb boy in a cultivation clan. Because his spiritual roots are incomplete, he is sent to work in the herb garden behind the mountain. After an accident activates his ancestral jade pendant, he gains a shared dantian.
Inside it lies half an acre of black soil. The spiritual energy in the spirit herbs he grows can repair his spiritual roots, while water from the spirit spring stimulates mutations in their medicinal properties. This special ability allows him to secretly accumulate resources.
From then on, he navigates the clan and the powers of the nearby city, rises to prominence in secret realms, and joins the Qingyun Sect to avert a crisis. In the end, he embarks on the path to prove his Dao and become an immortal.
