Wang Ping sat up straight and said: "Mr. Cheng, when it comes to taking medicine, one must consider the individual's suitability, this point you are certainly clear about!"

  Cheng Ji nodded silently, he naturally knew this truth.

  Wang Ping'an continued: "I was originally weak, and after contracting dysentery, I first invited other doctors to come and take a look. The medicine they prescribed was similar to yours, Mr. Cheng, but yours was more suitable. However, because my body is weak, the prescriptions from those doctors were effective but couldn't cure me in time, so my dysentery turned into chronic dysentery..."

  "Oh, what's this 'resting dysentery' business?" Cheng Jisheng asked, perplexed.

  Wang Ping thought to himself, "This is hard to explain for the time being, I can't give him a lecture on theory!" He said vaguely, "It can be understood as a chronic illness that hasn't healed, so the condition has changed, let's just understand it this way for now!"

  Cheng Ji Sheng nodded again and didn't ask any more questions, quietly listening on.

  Wang Pingan said, "Your prescription is very effective. If I had used your prescription as soon as I fell ill, I would have recovered quickly. However, the dosage of your prescription also needs to be reduced a bit, otherwise I still can't take it."

  Cheng Ji Sheng stroked his beard and said, "I had the same idea, but I also thought that maybe the previous prescriptions were too crude and the medicinal effects were not strong enough, so I didn't reduce the dosage to attack...". Suddenly, he let out an "ah" and stared blankly, understanding what was going on. Having practiced medicine for half his life, there were some things that didn't need others to point out, just give him a lead and he could figure it out himself.

  Wang Ping'an smiled slightly and said: "I've been ill for a month, how can I still go to battle?"

  Cheng Jisheng slowly got up, his expression somewhat dazed, and staggered out of the study, standing in the courtyard, raising his head to gaze at the sky, lost in thought.

  Wang Youcai looked at him and then at his son, saying: "Alright, that's settled. I didn't quite understand, did you win or lose?"

  Ding Danru stood by and watched as Wang Ping'an spoke like a little adult, leaving the famous Cheng Shen Yi speechless. In the end, he simply went out to gaze at the stars, unable to help but laugh inwardly. She chimed in, "Young Master has won the argument, otherwise Mr. Cheng wouldn't have left!"

  Wang Youcai's face lit up with joy, and he chuckled: "I understand now!"

  The young man outside saw Cheng Jisheng coming out and stepped forward, saying: "Sir, sir?" Seeing Cheng Jisheng's dull eyes, he didn't speak up when his head was raised. He was startled and quickly said: "Sir, what's wrong with you?" Gently pushing Cheng Jisheng a little.

  Cheng Ji Sheng came back to his senses, ignoring the young man, and strode into the house. He made a deep bow to Wang Ping'an, saying: "It was I who used the wrong medicine. At the time, your body was already weak, but I used a large amount of nitrate, which led to excessive attack and damage to your spleen and stomach, making it impossible for you to absorb nutrients. But you cleverly added peach blossom decoction and astringent products, reversing the effect, so one dose took effect and your condition improved immediately. Cheng has learned from his mistake!"

  He paused, saying: "I have a request to make. Young master, which medical book did you see this prescription in? I am certain that it must be accompanied by case studies; may I borrow it from you for a look?" Just like a wine enthusiast seeing fine wine, he couldn't help but feel curious and really wanted to take a look at the medical book.

  Wang Ping thought to himself, "If you want to see a medical book, you'll have to live for hundreds of years more, at least until the Song Dynasty, before such books appear." He shook his head and said, "I really forgot which book it was!"

  Cheng Ji's face darkened, thinking that Wang Ping'an was unwilling to show him the medical book. He thought it made sense, a book that recorded such effective prescriptions must be priceless, and might even be a rare and secret volume, how could it be shown to outsiders? He said: "I was too presumptuous."

  Wang Youcai thought that Wang Ping'an was unwilling to let Cheng Jisheng see the book, so he praised his son in his heart. Although his son was young, he was very sensible and the medical book must be very valuable, it couldn't be given away to outsiders for nothing. He stepped forward to mediate: "Mr. Cheng has worked hard, please follow me to rest in the guest room!"

  Cheng Ji Sheng sighed, nodded at Wang Ping'an, and followed Wang Youcai out.

  Wang Ping'an felt quite comfortable in his heart and lay down again, but Ding Danruo didn't go to sleep. She asked: "Young master, your medical skills are even better than Mr. Cheng's. The illnesses he couldn't cure, you can. It seems that reading more books is indeed beneficial."

  Wang Ping'an shook his head and said, "That's not necessarily because Mr. Cheng's medical skills are not high, each profession has its own strengths, maybe he's not good at treating hemorrhoids, if it were a subject he's good at, his methods would be superb."

  Ding Dan nodded slightly, but her eyes turned towards the bookshelf, thinking: "I wonder what kind of medical book it is that can make a divine doctor surrender."

  Wang Ping'an understood the little girl's thoughts and said, "When I have time later, I'll teach you to recognize characters and read books. Who knows, maybe one day you can become a female divine doctor too!"

  Ding Ding's small face turned red as she said, "I'm just a woman, how can I become a divine doctor? I just want to learn more about brewing medicine so that in the future when Master falls ill, I can brew medicine for you and serve you well."

  "Are you hoping I'll be sick all the time from now on?"

  Ding Dan suddenly became anxious: "No, no, I absolutely didn't mean it that way!"

  "Just kidding, don't cry!" Wang Ping'an knew that the joke had gone too far, and Xiao Yatou couldn't take this kind of joke. He hastily said: "Alright, it's almost dawn, go to sleep!"

  The little girl finally agreed and blew out the candlelight, going to sleep in the outer room.

  The next morning, Wang Youcai and Yang came together, ordering the servants to set up a table of plain porridge and small dishes, accompanying their son for breakfast. Wang Ping'an asked about Cheng Jisheng, and Yang hummed, saying: "Last night was too late, Mother wasn't convenient to come out, and she was angry all night. As soon as it dawned today, I went to the guest room and scolded him severely. This old stubborn man has caused my son so much suffering, not to mention what he said about whom."

  Wang Pingan said, "Mother, why bother? Mr. Cheng may not be good at treating hemorrhoids, but he has a good medical ethics, and was brought out of the city in the middle of the night to see me, such character is worth making friends with."

  Yang patted his hand and smiled: "My son said it's good, then it's good. Next time I see him, I won't scold him if he doesn't do well."

  Two days later, Wang Ping'an took his medicine on time and his condition improved greatly. By the fourth day, the symptoms of dysentery had disappeared and he was recovering his health. He could already take a walk in the courtyard and would be able to run and jump freely after a few more days of rest.

  Wang Youcai and Yang were overjoyed, discussed it for a while, sent someone to deliver the invitation, inviting all the neighbors, and having a grand feast with friends.

  Relatives and friends received the invitation, all came to the door, Wang Youcai lavishly entertained, happily treated the guests, during the banquet, he talked about his son self-prescribed medicine to cure the disease, and in the middle of the night, he argued with Cheng Shen Yi to diagnose, Cheng Shen Yi was speechless, Wang Youcai boasted, in order to lift up his son, he also called Cheng Jisheng "Cheng Shen Yi", if his son could win the argument against Cheng Shen Yi, wouldn't that make him the "god of medicine" among the gods of medicine, and himself the father of the "god of medicine" among the gods of medicine...

  Relatives and friends are few who believe, after all, people from Jishengtang won't talk nonsense, only the Wang family says so themselves. A sickly child can create good medicine and even surpass the famous doctor of Xuzhou? This is just something to listen to, who would believe it? If the young master of the Wang family was really that capable, why did he suffer from illness since childhood?

  The house was in an uproar for two days, but Wang Ping'an didn't come out to entertain the guests. He stayed in his study reading books. His memories of being Young Master Wang had brought him many benefits. At least he could write beautiful small characters with one hand, and he could recite most of the books from memory. It seemed that the former Young Master Wang had spent more than a decade doing nothing but memorizing books, and now it was all coming in handy for him.

  After the days had calmed down, Yang saw that Wang Ping'an's body was getting better day by day, so he told him that tomorrow he would take him to Baota Temple to repay his vows. Some time ago, when he was ill, Yang sought the blessing of the Buddha and went to Baota Temple to pray for the Buddha's protection. Now that Wang Ping'an had indeed recovered, he could even open up his own medical prescriptions, which was absolutely impossible according to common sense, so it could only be explained by the protection of the gods and Buddhas. Therefore, Yang wanted to take Wang Ping'an to repay his vows and add more incense oil money to the temple, in order to ask the gods and Buddhas to continue protecting his son.

  Wang Ping'an didn't believe in gods or Buddhas, but he was willing to go out and take a stroll. Having been in the Tang Dynasty for some time now, he still hadn't seen the prosperity of the Zhenguan era. Being able to go out and walk around was just what he had in mind.
