During a high-stakes game against the 76ers, Grant Hill attempts a sharp change of direction on the hardwood. His high-friction sneaker catches, his feet tangle, and he collapses with an agonizing left ankle injury. Magic team doctor Joe Billings and a hospital physician run an MRI, declaring it a simple sprain requiring only two weeks of rest. Remembering Chen Yu's warning back in Miami, a skeptical Hill secretly calls Chen Yu to Orlando for a second opinion. Chen Yu arrives at Hill's luxury home and deploys his Eye of All-Seeing. He peers through the massive swelling and discovers hidden talar cartilage damage and micro-cracks around the surgical screws of Hill's implanted metal plate. These are injuries that will completely ruin Hill's career if he rushes back in two weeks. When Chen Yu insists on a strict two-month recovery period, Billings and general manager John Gabriel are outraged. Billings, protective of his authority and eager to rush his star back to secure ticket sales, calls Chen Yu an unlicensed rookie and a fraud. To resolve the deadlock, Gabriel drags Hill to the world-renowned Mayo Clinic in Jacksonville to consult with top Western orthopedic surgeons, setting up a high-stakes medical showdown that will either validate Chen Yu's system or destroy his budding career. As they depart for Jacksonville, Gabriel deliberately changes the departure time to leave Chen Yu behind, forcing Chen Yu to chase them by train. Chen Yu arrives at the Mayo Clinic alone, facing a hostile wall of elite medical professionals who are ready to dismiss him on sight. He enters the spacious waiting area where Billings sneers at his arrival, confident that the Mayo Clinic's advanced scanners will prove Chen Yu wrong and banish him from the professional sports world forever.

At the Mayo Clinic, prominent surgeon Kate Walsh conducts a thorough exam and agrees with Billings, seeing no cartilage damage on the scans because the massive swelling obscures the tissue interfaces. Billings mockingly demands that Chen Yu point out the damage on the tablet, attempting to completely destroy his professional credibility. But Hill, recalling how Penny Hardaway was physically ruined by the Magic's rushed timelines, decides to gamble his career on Chen Yu's confidence. Chen Yu demands twenty-four hours to prove his diagnosis by clearing the swelling. Operating in a Mayo hospital room under the watchful eyes of Chief of Orthopedics Alon Svenson and a group of curious residents, Chen Yu deploys a multi-pronged Eastern therapy. He uses his system-boosted Gold Level treatment effect on Acupuncture, targeting Hill's Yangchi and Xuanzhong acupoints, followed by fire cupping, moxibustion, and a custom Chinese herbal plaster. The next morning, Hill's swelling has completely vanished, revealing the cartilage surface with perfect clarity. A new MRI scan exposes the exact talar cartilage damage Chen Yu predicted. Svenson and Walsh are left in absolute awe, while a humiliated Billings flees the room. The Magic front office is left terrified of losing their ninety-three-million-dollar investment, but they still refuse to accept the long recovery timeline, setting up a clash between corporate greed and player safety. Svenson is so impressed by the immediate relief of his own chronic back pain through Chen Yu's needle placement that he offers Chen Yu a prestigious position and a fully funded research project at Mayo. Chen Yu turns down the offer, choosing instead to return to Orlando to oversee Hill's recovery, knowing that his refusal will force him to operate in a legal gray area without the backing of a major hospital.

To support Hill's two-month rehabilitation, Chen Yu needs to farm system experience points to unlock more therapeutic effects. He uses a ten-thousand-dollar advance from Hill to sublet a run-down surgical clinic from Javier Guardado near the TD Waterhouse Center. He immediately begins treating local patients, starting with the stubborn octogenarian Anthony Quinn, whose displaced lumbar spine he resets with a single, dramatic crack before applying a blood-circulating plaster. Magic player Monty Williams also visits, suffering from inner knee pain that Billings ignored; Chen Yu diagnoses pes anserine tendinitis and uses acupuncture to relieve the chronic strain. Chen Yu even travels back to Mayo to treat NFL wide receiver Keenan McCardell's swollen knee. Through this high volume of treatments, Chen Yu's system rewards him with two permanent skills—Basic Acupuncture Therapy Techniques and Basic Level Sports Massage, both granting a five percent efficacy bonus. However, while Chen Yu builds his reputation, the Magic front office begins a dangerous media campaign, publishing photos of Hill looking healthy to pressure him back onto the court. During a community outreach event at Saint Mark's Primary School, the players take notice of Chen Yu's incredible diagnostic skills when he identifies Monty's knee pain just by looking at his posture. Chen Yu hands out his business cards, directly bypassing Billings to build a private clientele among the players. This makes Billings furious, leading him to deny Monty's request for rest and instead pump him with painkillers to force him onto the court. This escalating neglect of player health forces Chen Yu to realize that the entire Magic management is rotten, setting the stage for a public confrontation.

The tension peaks when the Magic front office forces Hill to play a halftime charity game to show the fans he is healthy, while head coach Doug Rivers runs an exhausted Tracy McGrady into the ground. Realizing the front office is willing to destroy its players for ticket sales, Chen Yu decides to fight back. He joins Dr. Kate Walsh on NBC's national show, NBA Showtime, and publicly exposes the Magic's medical staff as butchers who ignore career-threatening cartilage injuries. To solidify his claims, Chen Yu takes on the treatment of Penny Hardaway, whose knees were famously ruined by the Magic's rushed timelines. The public outrage is immediate and massive. When a league investigation reveals that Rivers and Gabriel also fixed a game against the Hawks to manipulate their draft standing, the owner Rich DeVos fires Gabriel and Rivers in a swift, merciless purge. Chen Yu's reputation as a medical savior is cemented, catching the attention of superstars like Patrick Ewing and even soccer legend Ronaldo in Europe, setting the stage for his global sports medicine empire. During his television appearance in New York, Chen Yu details the exact biological mechanisms of cartilage degeneration, explaining how forced play destroys joint longevity. He then travels to Phoenix to operate on Penny Hardaway, successfully reconstructing his knee using an artificial ligament. By the time the Magic's front office is dismantled, Chen Yu has already outgrown Orlando, preparing to build a state-of-the-art clinic in Phoenix and travel to Europe to save the career of Inter Milan's Ronaldo, leaving the greedy sports executives of the NBA trembling in his wake.
