Lin Muyang, a modern special forces military doctor, is an orphan who passed through the border gate of Dajing Dynasty. He possesses the internal skills of "Rejuvenation Jue" and the family tradition "Essence of Baicao Compendium". He has a silver needle in his left hand and a long sword in his right hand. He opens the "Rejuvenation Hall" in Yunzhou City. From setting up a stall in a ruined temple to becoming famous on the border, he used battlefield first aid to cure dystocia, allicin to fight the plague, gold needles to seal acupoints to control enemies, and lancet debridement to revolutionize surgery. He also became friends and foes with the mysterious female doctor Liu Waner, who jointly exposed the royal family's secret medicine conspiracy and promoted the publication of the "Thirty-Six Methods of First Aid for Trauma". The lights of the hospital were bright, and there was both the ferocity of the gangsters who smashed the place, and the warmth of the free clinic; there was the honor of being invited by Taiyuan Hospital, and there was the iron law of "doctors don't kill" by burning the poison code. When he stayed up for three days to save thousands of people during a major earthquake, he finally realized that "there is no disease in the world, so why do we need a medical center?" - This benevolent blade will eventually kill all the diseases in the world!
