Qiu Tingxuan was shocked and forgot his father's presence, exclaiming: "Nine taels for cassia twig?"

  Qiu Wenpu glared at him, not wanting to scold his son in front of outsiders. He just gave him a look, reminding him to mind his manners. A scholar should not be so flighty. Even if Mount Tai were to crumble, one should remain calm and composed. What's more, it was only a medicinal herb!

  Cheng Ji Sheng stroked his beard again, this time not thinking of sneaking a smile, but in shock. He had been practicing medicine for many years, and every time he wrote a prescription, he was cautious and careful, emphasizing gradual progress. He would rather have patients take several more doses of decoction than increase the dosage of a certain drug in one dose, let alone multiply it several times!

  Qiu Tingxuan was glared at by his father, but he was still surprised in his heart. This concerned his father's illness, and even if he wanted to maintain his composure, he couldn't really calm down. He said again: "Wang... younger brother, I'm a few years older than you, so I'll call you younger brother. Dare I ask, are you certain that this use of cassia twig is treating wind-cold?"

  He couldn't think of any more polite words, so he asked like this. Although he didn't know how many prescriptions and had no medical skills, the famous prescription of Guizhi Tang was still familiar to him. This prescription not only cures wind-cold but also other diseases, with different dosages of medicine, it's not as simple as writing casually with a pen.

  Wang Pingan said: "Medication should be tailored to the individual, and based on Mr. Qiu's symptoms, increasing the dosage of Guizhi is acceptable!"

  Cheng Jisheng and Qiu Wenpu exchanged a glance, nodded slightly, and Cheng Jisheng suddenly smiled: "The key to Guizhi Decoction is that the amount of cassia twig should be equal to the amount of peony. For such a renowned formula passed down through generations, I rarely make changes. Even when making adjustments, I exercise extreme caution!"

  He slowly unfolded the paper ball and spread it on the table, saying: "Actually, I also increased the dose of this medicine, but I have never opened such a prescription before, my heart was trembling, so when Mr. Qiu came to find me at that time, I didn't take out the prescription, but instead hid it in my sleeve. This is really getting older and more timid!" After self-mockery, the paper ball had unfolded, revealing the words on top!

  Qiu Tingxuan let out a loud "ah" as he saw that the paper read "Gui Zhi Liu Qian", although it was much less than Wang Ping'an's nine qian, but for treating his father's wind-cold, it was still a large dose!

  Wang Ping'an glanced at the prescription written by Cheng Jisheng, a smile appearing on his face. It seemed that both of them had discovered the same problem. The reason why Cheng Jisheng hadn't dared to take it out earlier was because the prescription was too famous and he didn't dare to add or subtract large doses, so he hadn't dared to show it to Qiu Tingxuan until now when all three of them confirmed it together.

  Qiu Wenpu patted his head and let out a long sigh, saying: "Master Cheng said that the older you get, the smaller your courage becomes. Here, I'm the oldest, and it seems that I'm indeed the one with the smallest courage!" He sat up straight and unfolded the paper ball in front of him.

  Wang Ping'an hummed in agreement, seeing that the paper read "Guizhi five mace", indeed the smallest dosage among the three. He said: "I'm not talented, yet I coincidentally thought of the same thing as the two seniors, it turns out we all discovered that to treat Old Master Qiu's wind-cold, the Guizhi in the Guizhi Decoction was actually the one that went wrong!"

  Cheng Jisheng also nodded and said, "Not bad, but there are still some minor differences."

  Qiu Wenpu was the most knowledgeable here, but when he finally spoke, he only said four words: "How to distinguish?"

  Cheng Jisheng made a please gesture, Wang Ping'an is the largest dosage here, although he is the youngest, but the differentiation of medicine and reason is not divided by age, it's only divided by the level of skill!

  Wang Ping'an cleared his throat and said, "Zhang Zhongjing's prescription has been refined through thousands of hammerings and hundreds of refinements, and has gone through countless differentiations, so it will not be wrong. Therefore, our differentiation should not be discussed from the perspective of pharmacology, but rather from the perspective of the doctor himself."

  He looked at Qiu Wenpu and said, "Mr. Qiu is well-versed in medicine, and for minor illnesses like wind-cold, he can prescribe on his own with a calm mind. However, after using Guizhi Tang first and having an adverse reaction, then using Mr. Cheng's prescription and also having an adverse reaction, at this point, even if another prescription is written, the mindset will never be calm again!"

  Qiu Wenpu slowly nodded his head, it was indeed the case, otherwise he wouldn't have changed the prescription afterwards, but didn't dare to use it again.

  Wang Pingan said, "At first, Mr. Qiu only thought about how to cure the disease, but now he thinks not only about curing the disease but also about how to prevent himself from being harmed again. So you are cautious in prescribing medicine and add the smallest dose possible. This has nothing to do with the level of medical skills, it's just that I'm afraid of violating the taboo of not treating one's own family members, so I dare not take action. Am I right?"

  Qiu Wenpu sighed and said: "What Ping'an says is just like what I saw with my own eyes!"

  Wang Ping'an turned his head to Cheng Jisheng and said, "Mr. Cheng prescribes the prescription, I'm afraid he thinks more about it. Old Mr. Qiu only thinks of two points: cure the disease and don't hurt the body, but you think even more than Mr. Qiu!"

  Cheng Ji let out a sigh, wanting to shake his head and nod at the same time. He couldn't help but let out another sigh. Qiu Tingxuan asked, "What's bothering you?"

  Wang Ping'an smiled and said: "If I say it out loud, it would be offending someone. Let's just keep it between the three of us."

  Cheng Ji Sheng waved his hand and said, "Let me say it myself. What I've been thinking about is how to avoid harming myself as a doctor after the prescription is opened! Alas, once bitten by a snake, one fears the hemp rope for ten years!" He recalled the small mistake he made when he was in Chang'an.

  "Wang Ping softly comforted him: 'It's human nature, can't be helped, Mr. Cheng doesn't need to worry.'"

  Qiu Wenpu also said: "Mr. Cheng, don't blame yourself, this is a common human emotion!" He then turned to Wang Ping'an and said: "Mr. Cheng's medical skills are higher than mine, the dosage he adds is also higher than mine, Ping'an, you have opened up the largest dosage, I suppose your medical skills are even higher than Mr. Cheng's?"

  If someone else said this, Cheng Jisheng would have jumped up in anger. He can admit that his medical skills are not good, but others cannot say such things. However, the one who said this was Qiu Wenpu, and he felt there was some truth to it as he looked at Wang Ping'an, wanting to hear his explanation.

  Wang Ping'an waved his hand repeatedly and said, "No, no, no, my medical skills are not much better than others, it's just... I think a little more!"

  Qiu Tingxuan chimed in from the side: "The more you think about it, the more dosage you add, what else are you thinking too much about?"

  Wang Ping'an smiled and said, "What I was thinking most about was how to make a prescription that could cure the illness of my good friend, and also take this opportunity to meet Qi Shan's master, whom I have admired for a long time. What I thought about the most, I added the most dosage!"

  Cheng Ji was born with a smile, Qiu asked Pu but burst into loud laughter. The two of them knew that things weren't like this, but the words sounded pleasant to their ears. This young man is indeed good at socializing!

  Qiu Wenpu smiled and then coughed, Qiu Tingxuan hurried forward to attend to him. After a moment, Qiu Wenpu said: "It's alright, go back and tell your good friend that I've taken a look at this prescription and it's completely usable, let him take the medicine with peace of mind." He paused for a moment, then said: "Your good friend will definitely thank you."

  Wang Ping'an stood up with a smile and bowed his hands: "Thank you for your kind words, Mr. Qiu."

  Qiu asked Pu if he was tired, Wang Ping'an and Cheng Jisheng bid farewell and came out. Qiu Tingxuan personally saw them off. When they reached the door, Qiu Tingxuan asked, "I don't know how long it will take to see the effect after taking the medicine?"

  "Wang Pingan said: 'If taken now, it will take effect by tomorrow morning, and only one dose is needed!'"

  Qiu Tingxuan said, "May I trouble you two to stay a bit longer? This prescription is good, but as a son, I still have concerns. Please forgive me if I've offended you, and I hope you can understand!" He now truly admired Wang Ping'an, his favorable impression deepened, and his attitude became much more amiable.

  "Wang Ping'an hastily said: 'Alright, of course alright. I'll stay behind, Mr. Cheng you go back first!'"

  Cheng Ji shook his head and said: "I'm not leaving either. Anyway, you won't be able to sleep tonight, so it's just as well that we chat with Ping An."

  Qiu Tingxuan said that the servant was slow, and went to let the family servant decoct the medicine. The Guizhi Tang had medicine at home, no need to go out and grab it again.

  Wang Ping'an had originally brought two little maids with him, intending to have them decoct medicine, but seeing that the other family didn't need it, he also gave up and followed Cheng Jishi out of the small courtyard to the front academy.
