In the ninth generation, the hidden Chinese medicine genius Lin Wangshu was forced to join the world and reopen a century-old medical clinic in the old alley of Jiangcheng. A silver needle in one hand can cure an emergency in an instant, while three doses of decoction can make a persistent disease silent. But he was surrounded by capital, ostracized by his peers, surrounded by beauties, and ridiculed by his ex-girlfriend. When the demolition bulldozers came to the city, when everyone was waiting to see his joke - he smiled slightly and twisted the silver needle lightly. It has been passed down for thousands of years and has since then detonated the urban world. See how the descendants of the poor people use their benevolence as a shield and silver needles as swords to blaze a trail for traditional Chinese medicine in the tide of the times!
