Ling Feng, a disciple of the secluded Wuxiang Sect, descends the mountain to temper himself in the mortal world. He is skilled in the sect’s secret silver needles and excels at countering poison and evil, as well as planning and turning the tables.
His junior sister, Murong Shanshan, accompanies him. She is only twelve, yet her martial talent is peerless among her peers and she is unbeatable in close combat. Cute and sweet-natured, she has spent her life devoted to one thing: food.
Beneath the bustling city, undercurrents run deep. Local evil cultivators are entrenched, while sinister doctors from beyond the borders steadily infiltrate. Gu arts, strange paths, and alien forms of cultivation emerge one after another.
With a single needle, they unravel every sinister scheme; with a single punch, they sweep aside enemies on all sides. The two travel together across the mountains and rivers of China, making a living and filling their bellies as they investigate a far-reaching conspiracy of darkness and uncover long-buried secrets from ancient times. They temper their hearts and comprehend the Dao in the mortal world, protecting humanity through the righteous path of medicine and martial arts.
