Background / History

Physician of Blackstone Town

Master Wu practiced medicine in Blackstone Town for decades, earning widespread respect as the physician of its only clinic. He took Lin Yuan in years before the story began; Lin Yuan believed he would otherwise have frozen to death in the streets. Master Wu initially did not know that the boy was the Lin family’s second young master 1 4.

His family’s inheritance centered on medicine. One ancestor, an imperial physician, created the Five Qi Converging to the Origin Art after traveling widely and studying ancient texts. The lineage preserved the method for hundreds of years, but its extraordinary talent requirements prevented anyone from mastering it. Master Wu himself attempted it for several years in his youth without success 2.

Accepting Lin Yuan as His Successor

When Lin Yuan requested another aptitude examination, Master Wu discovered that his previously mediocre bone aptitude had become exceptional. Although Lin Yuan attributed the change to a strange fruit, Master Wu privately recognized that the explanation did not account for such an extraordinary transformation. He chose not to demand the boy’s secrets 1 2.

Master Wu retrieved the ancestral manual from beneath a floorboard and accepted Lin Yuan’s formal bow as a disciple. He entrusted him with the cultivation art and the lineage’s unresolved hope: discovering the unique result promised to someone who entered the First Rank through internal tempering 2.

After treating the wounded Lin Jiu, Master Wu learned about Lin Yuan’s family background and the attempts on his life. When assassins approached the following morning, he publicly declared Lin Yuan his disciple and heir. His standing among the townspeople helped shield Lin Yuan from further immediate attacks 3 4.

Escape to Ping’an County

The discovery of deserters near Blackstone Town prompted Master Wu, Lin Yuan, and Lin Jiu to flee. They escaped bandits blocking the town’s exit, but subsequently encountered Liu Lie’s deserter group. During the journey, Master Wu confirmed that Lin Yuan had begun cultivating the ancestral method and wept with joy 5.

When soldiers surrounded him and Lin Yuan, Master Wu prepared to use a life-staking needle technique to secure his disciple’s survival. Lin Yuan stopped him and defeated the attackers. Master Wu then helped stabilize the gravely wounded Lin Jiu before the group continued to Ping’an County, entering through a hole in the city wall 6 7 8.

Fulfillment of the Wu Lineage’s Inheritance

In Ping’an County, Master Wu continued treating Lin Jiu’s depleted blood essence. He prescribed century-old ginseng and a Qi and Blood Pill, later helping Lin Jiu channel the pill’s medicinal power during his recovery 7 10 22.

When Lin Yuan revealed that he had reached the First-Grade Qi and Blood Realm and formed five illusory internal organs, Master Wu examined him personally. Discovering that the method doubled vitality, strength, and other attributes brought him to tears. Although he doubted that such a demanding art could easily spread the lineage’s name, he was deeply satisfied to learn its secret within his lifetime 22.

He later lived at Lin Yuan’s residence, where Lin Liu attended him. Concerned that the painful Tyrant Body Art was unsuitable for his age, Lin Yuan instead developed a Human Grade version of his familiar health-preserving fist routine 40 41.

Appearance

• Aged features: Cloudy eyes, facial wrinkles, and a beard 1 2.
• Later-life routine: Practices slow health-preserving boxing in the courtyard 15 41.

Personality

Master Wu is protective of Lin Yuan without being unquestioning. He worries over the boy’s troubles, scolds him when violence turns the clinic into a murder scene, and nevertheless uses his reputation—and is willing to risk his life—to protect him 1 3 4 6.

He takes pride in his medical reputation and reacts indignantly when Lin Yuan suggests that an earlier aptitude examination might have been mistaken. At the same time, he respects his disciple’s privacy, declining to press either the secret behind his changed aptitude or the scent of blood on him after an outing 2 10.

The Wu Lineage’s unfinished mission matters deeply to him, but his response to its fulfillment is tempered by practicality: he recognizes both the method’s extraordinary effects and the difficulty of finding anyone talented enough to cultivate it 22.
