"Sure enough, I can't hide it from Madam Gu." said the prince.

　　The prince opened the study door and looked outside. No one was outside, so he closed the door again and said, "Old man Zhang was poisoned by Zhang Yingzi."

　　Even Li Mumu had never dared to think of this possibility.

　　At this moment, it sounded like he was not standing steadily and was swaying.

　　Even Gu Shangqing felt a sense of unreality.

　　He took two deep breaths to calm himself down a little, but he was still shocked. "Did Zhang Yingzi do that?"

　　The prince nodded.

　　Li Mumu clenched her fists and said angrily, "She... is she still human?"

　　"Old Man Zhang loved her so much, but she actually poisoned him!" Li Mumu said angrily, "But why did she poison Old Man Zhang? What good would it do for her?"

　　"We don't know yet. We are worried that there are other accomplices in the palace, so we haven't arrested them for interrogation." The prince said, "But based on the current clues, the poison should have been given to her by the female teacher that Old Man Zhang hired for Zhang Yingzi during Chong'an."

　　The prince told Li Mumu and Gu Shangqing the results of the secret guards' investigation, "Zhang Yingzi brought Old Man Zhang to Beijing to seek medical treatment. There is a spike in the palace who is unknown and has contacted Zhang Yingzi."

　　"Zhang Yingzi gave the poison to the maid, and in exchange, the maid gave the antidote to Zhang Yingzi." The prince said, "I guess that the lady must have promised Zhang Yingzi that as long as Zhang Yingzi poisoned Old Man Zhang and brought him to the capital, someone would find a way to contact Zhang Yingzi."

　　"At that time, Zhang Yingzi only needs to hand the poison to the person who contacted her, and she can exchange it for the antidote from the other party." said the prince.

　　"The antidote obtained from Zhang Yingzi was given to Imperial Physician Lu, who developed a new medicine based on that antidote," said the prince.

　　After hearing the prince's words, Li Mumu understood the emperor's intention.

　　The antidote developed by Doctor Lu based on that antidote may not be exactly the same as the original antidote.

　　This means using Old Man Zhang as a guinea pig.

　　However, apart from the antidote given by the prince, there is no other way to obtain the antidote.

　　I can only take the risk and give it a try.

　　If he didn't try, he would have been poisoned and would have died one day.

　　And looking at Old Man Zhang's current condition, I'm afraid that day is not far away.

　　Just one try.

　　Besides, it is hard to say whether the antidote Zhang Yingzi obtained from the other party is real.

　　I've asked Dr. Lu to study it, and I think it should be correct.

　　The original antidote is no longer useful.

　　However, Li Mumu estimated that if Doctor Lu's antidote was useful, the saint would not even touch the original antidote that Zhang Yingzi had exchanged for.

　　The enemy's things are exactly the same, and even a saint would find it difficult to trust them.

  "Maybe now he is serving Zhang Laohan?" Li Mumu asked Prince.

  "Yes." Prince nodded, "Doctor Lu is already waiting outside Old Man Zhang's hospital."

　　So, Li Mumu and Gu Shangqing hurried to Old Man Zhang's house with the antidote.

  As a result, Li Mumu and Gu Shangqing quickly took the antidote to Zhang Laohan's house.

  "This is the medicine developed by Imperial Doctor Lu." Gu Shangqing did not say it was an antidote. He thought, no matter what happens in the future, it would be better not to let Old Man Zhang know the truth for the time being.

  Poisoning is harmful to the body. Even after taking the antidote, Old Man Zhang's body has been damaged by the poison and he needs to recuperate.

  After this incident, I'm afraid that my body, which could have lived to eighty or ninety, is no longer viable now.

  If Zhang Laohan knows the truth, who knows whether Zhang Laohan still has the will to live.

  Old man Zhang was surprised when he heard this. "Really? I... my illness can be cured?"  

  "Let's try it first. Since Doctor Lu has made the medicine, even if it can't cure the disease all at once, it will definitely be better than before." Gu Shangqing didn't know how effective the antidote was, and he didn't dare to guarantee it to Old Man Zhang.

  Old man Zhang nodded.

  The servant helped Old Man Zhang up.

  Gu Shangqing poured a medicine from the porcelain bottle to Zhang Laohan.

  The medicine naturally won't work that quickly.

  However, in order to prevent accidents from accidents, Lu Taiyi stayed from Zhang Laohan and stayed in Gu's house.

  "Doctor Lu, you should go and rest." Old Man Zhang advised, "I'm actually fine now. If anything goes wrong, I'll call you again."

  "It's okay. I'll sit here and I won't feel tired." Since this concerns the saint, Doctor Lu did not dare to slack off.

  At night, the moon was high in the sky, but it was pitch black outside, without any light.

  Although Old Man Zhang was tired, he felt a lot lighter, so he told Doctor Lu about this.

  Doctor Lu Doctor Lu felt the pulse of old man Zhang and said, "The old man is recovering well."

  Doctor Lu prescribed some conditioning medicine and gave it to Gu Shangqing.

  After leaving Old Man Zhang's house, he whispered to Gu Shangqing and Li Mumu, "The toxins in Old Man Zhang's body have not been completely cleared. After all, he has been poisoned for a long time, and it is not possible to clear them all so quickly."

  "I added drugs to the prescription that promote excretion. I will come to check Mr. Zhang's pulse tomorrow after he has excreted the remaining toxins. From the pulse I saw just now, the toxins have been mostly eliminated, but because he has been poisoned for a long time, all his internal organs have been damaged, so he needs to be properly taken care of." Doctor Lu said, "I also wrote a prescription for warming and nourishing. Once all the toxins are eliminated, we can start warming and nourishing Mr. Zhang. Don't give him too much nourishment in terms of diet at the beginning. Take it step by step, slowly."

  "Thank you, Doctor Lu." Li Mumu said.

  "I still have to go back to the palace to report." Doctor Lu said, "Come back tomorrow. If there is anything, please let me know at any time."

  "I send Lu Taiyi." Gu Shangqing sent Lu Taiyi outside the door and watched Lu Taiyi get on the carriage.

  Doctor Lu returned to the palace and told the saint about Old Man Zhang's condition. "At present, Old Man Zhang's condition is normal. Even if he takes Zhang Yingzi's antidote, he will not recover immediately. But it proves that there is no problem with the antidote."

  As the Mid-Autumn Festival banquet approached, the secret guards kept a closer eye on Zhao Xia.

  But I never saw her contact anyone.

  But one thing, Zhao Xia changed his state that he had not been close to who he had been in the past, and at first he went to find the food bureau and the last palace people in the royal dining room to chat.

  She actually started chatting with two of the more intimate ones.

  When they met, Zhao Xia often gave her little gadgets she made herself.

  For example, a handkerchief, a purse, etc.

  The Shangshi Bureau and the Imperial Kitchen naturally provided some food for Zhaoxia.

  After a few visits, the relationship became better and better.

  The secret guards checked the two palace maids that Zhao Xia was looking for.

  They did not have any suspiciousness, and they had not had a relationship with Zhao Xia before.

  If this is true, I am afraid that Zhao Xia will be innocently implicated.

  At noon on the day of the Mid -Autumn Palace Banquet, Zhao Xia came to the royal dining room and talked with the small palace people who had made it.

  At this time, a young eunuch shouted at the door: "Shunzi, Eunuch Wang is calling you."

  "I'm coming." Shunzi, who had a good relationship with Zhaoxia, responded and said to Zhaoxia, "Sister Zhaoxia, Eunuch Wang is looking for me. I don't know when he will be back. You go back first, and I will find you when I'm done."
