The Gu family in Yizhou, a declining family with an ancestral tradition of medical divination, is now almost unable to open the medical clinic. The Qian family came to the door with a debt deed and threatened to annex the medicine field within three days.
The concubine Gu Changfeng was holding the tea cup without even raising his eyelids - he was a doctor of Chinese and Western medicine and a researcher of Taoist I Ching in his previous life. When he traveled here, he was full of knowledge, but he didn't want to say a word more.
Just say: "You will vomit blood and fall to the ground within three days."
Only then did the people of Yizhou City discover that the good-for-nothing bastard of the Gu family who drank tea all day long could tell the difference between life and death with a single glance, that three silver needles could bring people back, and that the I Ching Bagua and Yangming Meridians were like common sense to him.
The shopkeeper of the Qian family laughed and left. Three days later, it was fulfilled on time.
