Those Years I Worked as a Miracle Doctor in the Stars

[The title is a little too chuuni. I'll replace it when I think of a better one, and the blurb still needs polishing.] Wu Yao, heir to a family of traditional Chinese medicine practitioners, transmigrated to the interstellar age and discovered that his profession had fallen into complete decline. Refusing to accept that, he ignored everyone's objections and set up a small stall to treat people for free. Everyone thought he was crazy. How could he treat anyone without medical equipment or factory-made medicine? At last, someone who'd come to watch the spectacle held out his wrist. "Come on, take a look." Wu Yao lightly placed his fingers on the man's wrist and furrowed his brow. The man scoffed. "What's wrong? I just had a full checkup yesterday." Unwilling to say much to someone so flippant, Wu Yao replied, "You should get checked at another hospital." Seeing how certain he sounded, the man left, half convinced. Two days later, he came running back, overjoyed, and clasped Wu Yao's hand in gratitude. "I caught hantavirus on a trip a while ago. It was still in the incubation period, so the checkup didn't catch it!" After that, more and more people came to see him. He diagnosed illnesses in the sick, and even those who weren't sick found out what they'd eaten that day. Getting an appointment at a medical center was far too complicated, but here, he could make a diagnosis in just a few seconds. The people were endlessly grateful to him and brought him gift after gift. Rare treasures piled up all over the room, but the young man was unmoved. He couldn't even be bothered to raise his eyes. "Maybe... give me a banner instead?" * Wu Yao became famous, but he also faced plenty of criticism. His diagnoses were always accurate, but no one had ever seen him actually treat anyone. Could he really be called a doctor? Who could have guessed that he would pack up his stall and leave the home planet with nothing but a bag of silver needles? It was six months before news of him resurfaced, when a news outlet covering the war released his photo. In front of a stretch of ruined, desolate wreckage, the simply dressed young man knelt on the ground with a medical kit on his back, giving acupuncture to a child who had lost his hearing in the war. In the tents behind him were thousands of refugees displaced by war who could not afford medical care, along with soldiers who should have died on the battlefield. Massage, acupuncture, pulse diagnosis, herbal medicine, prescriptions. Wu Yao had spent years honing these skills. Every one of them was every bit as good as technology, and every one of them was vital to saving lives. With one person and one medical kit, he traveled through the smoke and chaos of war, saving everyone trapped by illness and pain. He was truly the greatest doctor of all.
