Agronomy PhD Chen Bo transmigrated to the cultivation world, possessing the rare Heavenly-grade Wood Spiritual Root. Loathing the deceit and treachery of the cultivation world, he resolutely abandoned the immortal path to take root in the mortal dust and research hybrid rice. His Dao companion Liu Yunxi divorced him because he chose the mortal world. Over four hundred years of dynastic changes, Chen Bo selected superior seeds, promoted farming techniques, benefited all people with agronomy, and accumulated immeasurable merit. He saved the orphan girl A He, and sacrificed his spiritual root to save his beloved daughter. The ancient great fiend Hou emerged to wreak havoc on the world, and Chen Bo relied on centuries of world-saving merit to prove the Dao and become a sage, slaying the fierce fiend and establishing the ironclad boundary between immortals and mortals. Seeking not immortal longevity, he only asked to scatter grain seeds and guard the mortal world's hearth fires in abundance year after year.
