After Tang Zheng finished eating, Cheng Ying packed up and left with the food box. Tang Zheng looked at Cheng Ying who was leaving, maybe he thought too much, how could a teenage girl know so much. He and Cheng Pu are sworn brothers, and Cheng Ying has always regarded herself as her own brother, perhaps because Cheng Pu left Rinshan and Cheng Ying pinned her thoughts on Tang Zheng for her brother. Tang Zheng shook his head, no longer thinking nonsense, and put his mind into dealing with government affairs.

"Childe, there is a person named Zhang Ji outside who wants to see you by name." Just as Tang was about to get up and move, Zhang Chao knocked on the door and came in. "Zhang Ji?" Tang Zheng frowned and thought for a while, it seemed that there was no celebrity named Zhang Ji in history that he knew. Forget it, don't worry about inviting people in, Tang Zheng said to Zhang Chao: "You go and bring people in." Zhang Chao heard Tang Zheng's order and was about to turn around and go out, but he heard Tang Zheng say: "Forget it, since people want to see me by name, I'll go out with you." Tang Zheng followed Zhang Chao and walked towards the living room.

After Tang Zheng arrived at the living room, he saw a middle-aged man dressed like an old farmer in his thirty-four or fifth years looking at the layout of the living room, nodding from time to time, obviously satisfied with the layout of this living room. "I don't know what the seniors named to see the kid?" Tang Zheng gave a junior salute to the middle-aged man and asked. "Hahaha, the old man heard that there is a virtuous person in Youbeiping, not only on the Ma Ke army, but also on the Ma Ke Anmin, and even the medical skills have profound attainments." The middle-aged man looked at Tang Zheng, he was in a high position at a young age, and he was still amiable, without a trace of arrogance after the young man's ambition. This son is not simple, and I don't know who can train such a talent. "The seniors have won awards, these are just false rumors outside, and the younger generations can't do without everyone's help today. The seniors will not just praise the juniors! "Hahaha, the old man heard that you have a deep knowledge of medical skills, the old man came back from outside the customs and passed by Youbeiping and heard that Nongduwei had extraordinary medical skills and came to visit, and asked Nongduwei not to blame him if he was disturbed. By the way, the old man's surname is Zhang, and the single name is a machine word, and the table word is from Nieyang County, Nanyang County, Zhongjing. Tang Zheng couldn't help but widen his eyes when he heard this, Zhang Ji may not know this name many people, but the name Zhang Zhongjing represents a different one. The famous medical saint, his book "Treatise on Typhoid Fever and Miscellaneous Diseases" has influenced later generations for 3,000 years. Not to mention the principle of dialectical treatment he proposed, until Tang Zheng's later life, it was also the basic principle of learning Chinese medicine.

"The younger generation doesn't know that Doctor Zhang's arrival is far away, and the younger generation is here to compensate Doctor Zhang. Zhang Chao, don't go to tea soon. Tang Zheng saluted Zhang Zhongjing again, and then said to Zhang Chao, who turned around and went to make tea. The last time there was a plague, Tang Zheng sent people out to look for Zhang Zhongjing and Hua Tuo, but he didn't find these two. Unexpectedly, Zhang Zhongjing himself came to the door today, and Tang Zheng made up his mind to leave him in Rinshan.

"What kind of miracle doctor is not a miracle doctor, it is the duty of a doctor to cure the sick and save people, and the world always likes to exaggerate." Zhang Zhongjing waved his hand at Tang Zheng to signal him not to care about these red tapes. "The old man heard that you had countless people alive on the battlefield, and he even watched the wounded soldiers after you healed with his own eyes. Although they were missing arms and legs, they saved their lives, and you must know that the most casualties on the battlefield are often not those who died directly, but the wounded barracks after the battle. Because of untimely treatment or some other reason, the wounded barracks are the places where the deadliest people after a major war are the highest. I don't know how you treat it, can you discuss it together? Zhang Zhongjing looked at Tang Zheng with a look of hope, for a doctor who takes saving lives and helping the wounded as his own responsibility, any method that can save people is worth learning from them, and Zhang Zhongjing is no exception. Zhang Zhongjing looked at Tang Zheng and frowned, thinking that Tang Zheng was reluctant to say it, so he said: "Since Nong Duwei has no intention of sharing the treatment method with others, it is not difficult to force people in Xia, and it is not strange to be surprised by Nong Duwei." After speaking, Zhang Zhongjing saluted Tang Zheng, and Tang Zheng hurriedly said to Zhang Zhongjing: "What did Doctor Zhang say, the kid was a little distracted when he thought of some other things just now." Since Doctor Zhang can afford to look down on the kid, how can the kid have the truth of cherishing himself. It's just that the kid also knows a little bit about the more profound things of the fur, so the kid doesn't know, so the kid tells the doctor what he knows. Tang Zheng stepped forward to help Zhang Zhongjing and said to him.

"Hahaha, just knowing a trace of fur can live countless people, and the captain of Nongdu is too modest." At this time, Zhang Chao came in with the brewed tea, and Tang Zheng invited Zhang Zhongjing to take a seat and said, "I don't know if the divine doctor has paid attention to why the wound is red and swollen or ulcerated and pus after the injury." "Nong Duwei don't always call me a miracle doctor, the person who calls is uncomfortable, Nong Duwei can just call me Zhang Ji or Zhang Zhongjing, and I dare not be a miracle doctor." Zhang Zhongjing interrupted Tang Zheng's words and said. "How can it be, not to mention that Doctor Zhang has countless living people, that is, Doctor Zhang's medical skills and medical ethics are worthy of the admiration of younger generations. A miracle doctor senior deserves it. "The old man is a little older than you, you and I can just talk about it, and your medical skills are no longer below me." Zhang Zhongjing resolutely rejected Tang Zheng's title of miracle doctor. "In this case, I will call Doctor Zhang a senior, this is already a junior Gao Pan, if you talk to Doctor Zhang on the same level, you will be laughed at by others, and the younger generation has no tutor." Zhang Zhongjing saw that Tang Zheng was resolute, and accepted the title of Tang Zheng's predecessor.

"By the way, just now you said that the wound is red and swollen and then ulcerated and pus, isn't it normal?" Zhang Zhongjing asked Tang Zheng. Tang Zheng shook his head and said, "Although this is normal, I don't know if the seniors know why the wound is red and swollen, why it ulcerates and pus?" Zhang Zhongjing shook his head, he had been practicing medicine for so many years, and he really had never thought about why it was red and swollen and why it was ulcerated and pus. As far as I know, this is because the wound is infected by a small microorganism, and as for what a microorganism is, we can't see it with the naked eye, but it is real, and I call this microorganism bacteria. Zhang Zhongjing's mouth was stunned by Tang Zheng's words, and what Tang Zheng said was completely beyond his cognition.

"Some of these bacteria are good for humans, but most of them are harmful to humans. I've found that most bacteria are afraid of alcohol, and the higher the alcohol content, the more it kills those harmful bacteria. I re-distilled the liquor to extract the essence of the liquor, which I call alcohol, and when I spray the wound with alcohol, it is rarely red and swollen. After Tang Zheng finished speaking, he took out a bottle of alcohol from the cabinet and handed it to Zhang Zhongjing.
