Chen Xuan has lived in seclusion deep in the mountains for eighteen years. Born with malformed meridians, his divine essence is powerful, but his meridians could flare out of control and kill him at any moment.
His second master spent his life force and gave his life to extend Chen Xuan's by twelve years. Before dying, he left him an old copper coin and told him to go down the mountain and find his senior sister, Liu Lin, learn The Return to Origin Medical Canon and its unique Return to Origin Needling Technique, and save his broken body.
His eldest master drove him down the mountain, while his third master taught him how to cultivate medicinal herbs and guide qi.
When Chen Xuan first arrives in Jiangcheng, he finds Liu Lin, president of Ruikang Group, being pressured into marriage by Zhou Wentao of the wealthy Zhou family. Meanwhile, Liu Wenxuan, her second uncle, is secretly sabotaging her from within the Liu family. Someone has covertly spread soil-transforming powder in the medicinal fields, ruining all the herbs. The pledge Liu Lin made to the board is on the verge of collapse.
Chen Xuan, searching for his family with the copper coin, unexpectedly gets caught up in the conflict.
His third master's technique for guiding qi to cultivate seeds lets him counteract poisonous soil with disease qi and grow medicinal herbs several times more potent than ordinary ones. With his sect's ancient medical arts of observation, listening, questioning, and pulse-taking, he can identify the root of an illness at a glance.
But his meridians are damaged from birth. Every time he uses the qi-guiding technique, the disease qi in his body grows more chaotic. Only his senior sister Liu Lin can temporarily suppress the backlash by using her divine essence to administer acupuncture.
On one side, Zhou family martial artists close in, while schemes continue to unfold in the shadows.
On the other, a traitor in the Liu family watches like a hawk, coveting Ruikang's medicinal-herb supply.
And with the threat of his own imminent death hanging over him, he and his cool, formidable senior sister Liu Lin develop an unexpected bond through countless late-night acupuncture sessions, tending the medicinal fields, and joining forces to overcome one crisis after another.
Rooted in the city with ancient medicine, he takes on the power of the wealthy with spiritual fields and medicinal cultivation.
