With famine year after year, young Zhou Ming struggles to earn money for his mother's medicine in the streets. A bowl of cold gruel and half a barley cake are all he has to survive on. While taking shelter from the rain in a ruined temple, he spots a green duckweed plant growing suspended above a statue's head. Dew beads on its leaves without falling, and a green light flickers within it, just like the spiritual root said to have been born from primordial chaos.
A chance encounter with a crazed old Daoist sees the man casually drive off vicious tax enforcers, then foist this "hot potato" on Zhou Ming. The spiritual root of green duckweed conceals ancient secrets: one day of cultivation is worth ten years for an ordinary person, but it also draws the covetous eyes of the martial world. When the root transforms into a jade pendant and merges with his blood, Zhou Ming learns that the old Daoist's remnant soul resides within it, and that he has also taken on the weighty promise of "rebuilding the immortal sect."
From then on, the medicine basket gives way to a sword case, and his plain clothes are stained with dust and frost. He learns to cultivate among ordinary people and tempers his mind amid mountains of corpses and seas of blood. He once stood against a Golden Core cultivator to protect his neighbors, and nearly fell to demonic ways over a single misguided thought. When the spiritual root of green duckweed blooms with the light of primordial chaos, Zhou Ming gazes at the devastation across the Three Realms and finally understands: seeking the Dao was never about ascending to immortality. It means daring to uphold a clear and peaceful world with a mortal body when heaven and earth are collapsing.
With the immortal sects in decline and demons running rampant, watch as a boy from the streets takes up the green duckweed, treads a bloody path, and carves out a way of seeking the Dao in the mortal world that no one has ever walked before.
