Seeing that Zhang Yingzi was unpredictable, Mr. Yu knew that Zhang Yingzi was actually moving.

  The corner of Mr. Yu's mouth involved a sneer and said, "Could you, don't you always want to find a chance to enter Beijing?"

  "Your father is seriously ill. Chong'an is a remote place and doctors have limited medical skills. It is natural for you to bring your father to Beijing for medical treatment. Even Li Mumu cannot say anything wrong about you. Everyone in the world will praise you for your filial piety." Mr. Yu said.

  "Once you get the antidote and give it to your father, he will be safe and sound." Mr. Yu said, "What do you have to lose?"

  "And after this is done, you will have even greater benefits." Mr. Yu said, "You have always been dissatisfied with the reward given to Li Mumu, haven't you? By then, the reward you receive will be even greater than Li Mumu's. At that time, let alone Gu Shangqing, you can have anyone you want. If you are still obsessed with Gu Shangqing, I will even ask him to divorce Li Mumu and marry you."

  Zhang Yingzi's eyes lit up, she was really moved.

  Mr. Yu took out Bai Ri Qing from his sleeve and handed it to Zhang Yingzi. "Bai Ri Qing is colorless and tasteless. It can be put into tea or food."

  Zhang Yingzi lowered her eyes to take a look and asked again, "Are you sure the doctor can't find out it's poisoning?"

  "Can't find it, no matter how the pulse is, it is seriously ill." Mr. Yu said.

  Zhang Yingzi raised his hand tremblingly, and finally gritted his teeth, and was determined to take over the hundred days of Mr. too much.

  Just like that, Old Man Zhang suddenly fell ill one day.

  Zhang Yingzi first invited the doctor of Chong'an to show Zhang Laohan. No doctor saw the abnormalities, but none of the doctors cured.

  Zhang Yingzi took Old Man Zhang to Beijing, and Mr. Yu also left the Zhang family and disappeared.

  Along the way, wherever she went, Zhang Yingzi would ask local doctors to treat Old Man Zhang.

  In fact, it was to check whether it was really as Mr. Yu said. No doctor would find out that old man Zhang was actually poisoned.

  Along the way, no doctor could find out what was wrong.

  When she arrived in Beijing, Zhang Yingzi became anxious again.

  There are many people in Beijing, and the doctor's medical skills are higher than other places.

  If the best doctors in the capital can't find the cause, then let the imperial physician check.

  If he can't find it, Zhang Yingzi can be completely relieved.

  Although she didn't know what Mr. Yu was going to do.

  But as long as there is an antidote that can cure Old Man Zhang's poison, she will suffer no loss.

  According to Mr. Yu, this poison is hard to come by and must be extremely valuable.

  There is no need to waste it on ordinary people like Old Man Zhang.

  Mr. Yu must have greater ambitions, otherwise he would not have said that her status would be higher than Li Mumu's in the future.

  But when we came to the capital, the best doctor there was not there, but Doctor Li was also a very skilled doctor.

  Doctor Li's words that it was like a poison but not really a poison made Zhang Yingzi nervous again.

  Fortunately, Dr. Li didn't see anything in the end.

  Then, the imperial physician Lu from the palace came again.

  Even Lu Tai did not find out abnormalities, which made Zhang Yingzi completely relieved.

  After entering the palace, she went out of the palace to see Old Man Zhang and asked about his situation.

  Old Man Zhang said that there was no improvement, which meant that even Doctor Lu was helpless. Only then did Zhang Yingzi breathe a sigh of relief.

  However, no one has ever come to ask her for Bai Riqing's poison.  

  Zhang Yingzi was worried that no one would come to ask her for it.

  If no one came to ask her for it, how could she get the antidote to save Old Man Zhang?

  Could they only hope that Doctor Lu could find a way to cure Old Man Zhang?   While Zhang Yingzi was in such a dilemma, a little palace maid came to ask her for poison today.

  Zhang Yingzi always carries Bai Riqing with her.

  Because I was worried that it would be discovered if I left it at Gu's house.

  Fortunately, when she entered the palace, no one searched the things she carried carefully.

  She carries it close to her body, so it would be difficult to search her.

  "Where is the antidote?" Zhang Yingzi asked first.

  Zhao Xia took out a small porcelain bottle and secretly put it into Zhang Yingzi's palm, "But you'd better not give it to your father right away. Once this antidote is taken, your father will get better immediately. Your father's sudden improvement will arouse suspicion."

  "Anyway, there is still a long time away from poison hair, you don't have to be so anxious." Zhao Xia whispered.

  "I know." Zhang Yingzi said. She didn't want to arouse suspicion.

  Zhang Laohan's disease is so serious that he can close his eyes at any time. Suddenly, there is nothing at all. How can   he not doubt it ?

  Besides, she won't leave the palace in the short term.

  It is to take Zhang Laohan, and she will have to find a chance to go out of the palace next time or decide whether to take Zhang Laohan.

  "Is it possible to take this antidote in divided doses?" Zhang Yingzi asked, "It would be like taking medicine when you are sick, and you will get better slowly."

  "No." Zhao Xia said, "Poisoning is not a real illness. How can the antidote be taken in multiple doses? If you want your father to die from the poison, then give it to him in multiple doses."

  "If you can't, then you can't." Zhang Yingzi put away the antidote unhappily and handed Bai Riqing to Zhao Xia.

  Zhao Xia still measured Zhang Yingzi's size before leaving.

  Zhao Xia and Zhang Yingzi were unaware that their every move had actually been seen by the secret guards.

  After Zhao Xia left Ciyuan Palace, the secret guards followed Zhao Xia.

  Another dark guard rushed back to the royal study and went to report the saints.

  Zhang Yingzi has spies everywhere, so there is no need for secret guards to stay here all the time.

  "Zhao Xia came to measure Zhang Yingzi's clothes. When she approached Zhang Yingzi, she asked Zhang Yingzi for something called Bai Ri Qing. Zhang Yingzi then used an excuse to ask all the palace maids to leave."

  "The palace servants had already received the Queen's order. When Zhang Yingzi asked them to go out, they followed her orders." The secret guard said, "Zhang Yingzi handed a bottle of Bai Riqing poison to Zhao Xia, and Zhao Xia gave Zhang Yingzi a bottle of antidote."

  "From the conversation between Zhang Yingzi and Zhao Xia, it seems that Old Man Zhang was poisoned rather than suffering from an acute illness, and he will be cured after taking the antidote." The secret guard said, "Zhang Yingzi also asked if the antidote can be taken in several doses, so that it will look like Old Man Zhang's illness is getting better little by little. But Zhao Xia said no, it won't be effective if it is taken in several doses."

  After hearing this, the saint remained silent for a long time.

  "Saint, what should I do next?" Pan Lunchi asked.

  "Has Zhao Xia ever had contact with anyone else?" the saint asked the secret guard.

  "Not yet." said the secret guard.

  "I'm afraid she has accomplices in the palace." The saint said, "First, control Zhang Yingzi and don't let her leave the palace. Bring her antidote and give it to Doctor Lu. Let Doctor Lu study it and give it to Old Man Zhang to take. But the news that Old Man Zhang's health has improved must not be leaked. Ask Gu Shangqing to take good care of the family."

  "Zhang Yingzi is confined to the bedroom of the side hall of Ciyuan Palace. She is not allowed to leave under any circumstances. She is under stricter surveillance than before." The saint said, "But the fact that Zhang Yingzi is confined must not be spread to others."
