Yan Sanhe, an orphan with nothing but four bare walls to her name, happens upon half a bag of strange grain seeds that shimmer with silver light. She plants them, and by the next morning they’ve yielded a golden harvest and even cured her mother’s chronic illness. The secret of these “Spring-Rejuvenating Seeds” draws the attention of a mysterious man named Lin Wuyou. He looks frail, yet can fend off enemies with a branch, and he harbors secrets connected to the seeds. Even the piglets at home take an unusual liking to him.
The rent crisis is temporarily resolved, but one black-clad pursuer of the seeds after another appears. Lin Wuyou stays behind to protect her, then reveals an even more startling truth: the life force awakened by the seeds must eventually be repaid at a price. Yan Sanhe gradually discovers that the wild-grass embroidery on Lin Wuyou’s chest, the bloodstained clothes in the woodshed, and the engraved jade pendant all point to a world she cannot understand. And her connection to these mysterious seeds seems to be more than a matter of simply finding them.
When the hope of survival intertwines with an unknown price, and the warmth of rural life collides with the flashing blades of the martial world, Yan Sanhe grips her grain-cutting sickle. How will she forge her own path between protecting her family and uncovering the truth? Is Lin Wuyou’s protection a form of salvation, or another, deeper entanglement? What lies buried in this bag of seeds: a bountiful harvest, or a foreshadowing of fate?
