"I asked Doctor Li to check Zhang Yingzi's pulse carefully." Li Mumu said, "Zhang Yingzi is fine."

  "Although the possibility of acute illness cannot be ruled out, Doctor Li mentioned that it was poisonous but not poisonous, which made me think more." Li Mumu said, "What if... Old Man Zhang was really poisoned?"

  "I have this suspicion, too, especially when I think of the prophecy about the saint's sudden illness. The saint is healthy now, and the imperial physician takes his pulse every day and there is nothing unusual. If he suddenly falls ill, even if he was poisoned, it would probably be diagnosed and treated as a difficult disease." Li Zhiyin said, "But there is one thing I can't figure out."

  Li Mumu waited for Li Zhiyin to continue speaking.

  Li Zhiyin said, "But why did the other party go to so much trouble to poison Old Man Zhang? If it was poison, it must be extremely rare and precious to have such an effect that even doctors couldn't find it. How could it be used on Old Man Zhang so easily?"

  "I don't quite understand this, unless it is necessary to test the effect of the poison and whether it can be diagnosed after the poison is administered." Li Mumu said, "But why is it Old Man Zhang?"

  "However, this is just our guess." Li Mumu said, "It may not be true. Maybe Old Man Zhang is just suffering from an acute illness and happened to encounter a difficult and complicated disease."

  "Your Highness, I would like to ask the imperial physician to come out of the palace to see Old Man Zhang and see if he can figure out what's going on." Li Mumu said.

  "I'll go get the imperial physician," Li Zhiyin said immediately. "Also, send someone to Chong'an to check on Old Man Zhang and Zhang Yingzi to see if there was anything unusual around them before Old Man Zhang suddenly fell ill."

  Li Mumu nodded. Even if Li Zhiyin didn't say it, she would still suggest Li Zhiyin to do so.

  It has always been a pleasure to work with Li Zhiyin, as we always think alike.

  Li Zhiyin ordered someone to take her nameplate to invite the imperial physician, and the doctor invited was still Imperial Physician Lu.

  Li Mumu met Doctor Lu directly outside the palace, "Doctor Lu, I have to trouble you again this time."

  "Mrs. Gu, you're too polite." Doctor Lu said with a smile.

  When he heard that they were going to Gu's house, Doctor Lu was very happy.

  Given Mrs. Gu's etiquette, she would definitely prepare a lot of food for him.

  Whenever he has free time, he would go to Gu's Snacks and Gu's Fried Chicken to buy some food.

  I'm just embarrassed to go to Gu's house.

  "It's getting late now. Since Doctor Lu is here to see me at home, would you mind staying for dinner before leaving?" Li Mumu said with a smile.

  Doctor Lu was about to pretend to be polite, but suddenly he heard Li Mumu say, "For dinner today, I prepared maocai, spicy beef, malatang and braised food."

  These four are the main ones, and it is naturally impossible for a family to eat only these.

  Li Mumu knew that Doctor Lu liked to eat these, so she planned to ask the kitchen to add more dishes when she returned.

  On weekdays, the Gu family usually tells the kitchen what they want to eat.

  If it is not enough, the kitchen will make something else.

  When Doctor Lu heard these dishes, he could not even move and said, "Then I will have dinner at your house before leaving."

  After saying this, Doctor Lu sent the servant back home and told Madam Lu that she would not be coming home for dinner that night.

  Then he followed Li Mumu back to Gu's house.

  On the way to the courtyard where Old Man Zhang was, Li Mumu told Doctor Lu about Doctor Li's pulse diagnosis.

  Doctor Lu nodded. "It seems very strange."

  When they arrived at Old Man Zhang's yard, they heard that Doctor Lu had arrived. Everyone in the Gu family was also waiting for Old Man Zhang there.

  When Zhang Yingzi saw that it was Doctor Lu who came, she was not very happy.  

  She felt that Doctor Lu didn't like her.

  It's just that it was Doctor Lu who treated Gu Shangqing's injury last time, and now Li Mumu has invited Doctor Lu again, so it can't be said that Doctor Lu's medical skills are not good.

  Doctor Lu came to old man Zhang's bedside, first lifted up old man Zhang's eyelids and took a look, then observed old man Zhang's tongue coating.

  Then he began to take Old Man Zhang's pulse.

  After a long while, Doctor Lu finally said, "It is indeed strange. Doctor Li's description is correct. It is indeed like poison but not poisonous."

  "I still have no idea at the moment. I have to go back and look through the medical books, hoping to find some similar cases." Doctor Lu said.

  No one expected it to be so difficult.

  Li Mumu took out the prescription that Doctor Li had written for Old Man Zhang and gave it to Doctor Lu to read. "Doctor Lu, please take a look. This is the prescription that Doctor Li had written for Old Man Zhang. He didn't know how to treat him, so he just wrote a prescription for Old Man Zhang to recuperate first."

  "Do you think this recipe is feasible?" Li Mumu asked.

  Doctor Lu took the prescription and looked at it, then said, "It is indeed a prescription for warming and nourishing, but it is a little too mild. Given Old Man Zhang's current condition, ordinary warming and nourishing methods will have little effect."

  Li Mumu hurriedly asked someone to bring pen and ink.

  Doctor Lu changed a few herbs on the original prescription, and adjusted the dosage of some herbs, and gave it to Li Mumu, "Try this prescription first and see if it can make Old Man Zhang feel better."

  "At least clear the poison from his lungs first." Doctor Lu said, "There are still some things I don't understand. I'll go back and look up the medical books tonight."

  "Old man Zhang's health depends entirely on Doctor Lu." Li Mumu said.

  "I will definitely do my best." said Old Man Zhang.

  Li Mumu hurriedly asked someone to get the prescription and get the medicine.

  Li Mumu took Doctor Lu to the main hall and quickly asked the kitchen to prepare a few new dishes that she had decided to add after meeting Doctor Lu.

  Zhang Yingzi was waiting for the Gu family to send someone to invite her to have dinner together.

  This was not because she took the initiative to approach Gu Shangqing, but because she had to meet Gu Shangqing during dinner.

  Li Mumu always has nothing to say.

  Unexpectedly, Zhang Yingzi's idea was good, but when it was time to eat, it was the servants of the Gu family who brought the food boxes.

  Zhang Yingzi had an impression of this maid. She seemed to be someone close to Old Madam Gu.

  "Miss, I am Jinqiu who serves Old Madam Gu." Jinqiu said.

  Zhang Yingzi watched in surprise as she brought dishes to the table and listened to her explanation, "Old Madam Gu knows that the young lady is concerned about Mr. Zhang's health, so she must be worried about leaving Mr. Zhang alone here. Even if there are servants to take care of him, I'm afraid that the young lady, who is filial to her parents, will still be worried."

  "Instead of letting the young lady eat uncomfortably over there, let me bring the food here so that she can eat here and stay with Master Zhang." Jinqiu had a perfect smile on her face.

  Jinqiu is someone close to Old Madam Gu. Zhang Yingzi has gained some experience now and knows that she cannot get angry with Jinqiu, otherwise it would be disrespectful to Old Madam Gu.

  Even though she was unhappy, she had to endure it. She thought to herself, she didn't know whether it was Madam Gu's idea or Li Mumu's.

  Are you so worried about her meeting Gu Shangqing?

  It can be seen that they also have no confidence, fearing that she and Gu Shangqing will develop feelings for each other if they see each other too often.

  The more worried they were, the more proud Zhang Yingzi became.
