After rebirth, she became the prince's favorite

The emperor was extremely disappointed with his unruly and headstrong daughter and started to scold her, "Do you have a pig brain? Can't you analyze and think? You just believe whatever others say. What is your brain for? Is it for decoration?"

"Besides bullying people outside every day, what else do you do?"

Li Qingyun's face turned blue and purple, and he wished he could find a hole to crawl into.

"I know I was wrong, and I will never be so impulsive again. Father, please forgive me this time."

The emperor couldn't help but get angry when he saw his stupid daughter. "Go back, study more, don't be so stupid, you don't even know what's going on when you're being taken advantage of. If I know you bully others again, I won't forgive you."

Li Qingyun tried hard to hold back his tears, not daring to offend the emperor again, "I will take my leave now."

After scolding his daughter, the emperor looked at Li Hexiong's face with a gaze that seemed to be able to see through people, and did not move away for a long time.

I don’t know whether this matter is directed at him or Yang Yufei.

No matter who they are targeting, the prince is highly suspicious.

Li Hexiong's heart was beating fast and beads of cold sweat were oozing out of his forehead. Being stared at by the death gaze, he almost lost control and ran away.

However, reason told him that the more times like this, the more he had to straighten his back, behave frankly, and not feel guilty or afraid, so as to dispel the emperor's suspicion.

He suppressed his inner fear and met the emperor's gaze without any guilt, looking extremely calm.

"Prince, who do you think is so vicious that he used my birth date to carve a doll and cursed it with blood? That person has a vicious mind and even dared to plot against the emperor. I will not let him go if I find out."

"I don't know who did it, but since that person knew my father's birth date, it means he knows my father very well. He must be of a prominent position and of a certain age."

"Your Majesty, I have also heard of the curse of blood on the doll. But what I heard is different from what the Taoist priest said just now. What I heard is that if the person who used the evil spell to curse failed in his conspiracy, the power of the curse will backfire on the person who used the evil spell."

"I feel that Your Majesty is blessed with great fortune and is the Son of Heaven, and is protected by the gods. The curse has no effect. Those who have harmed Your Majesty will surely be punished, and their circumstances will get worse and worse, and they will not die a good death."

"Well said, those who do such evil things should be punished."

The emperor was in a better mood. "Take my recipes and check them carefully. Also check my bedroom and the Purple Palace where I hold court. Don't miss any details.

Yang Yufei was extremely alert and analyzed all the things that might cause allergies, and finally found the problem.

"The dragon throne has been smeared with a layer of moonflower pollen, a very light layer. The emperor must be allergic to the pollen."

"Pollen of the Moon Flower? I have never heard of such a flower. Imperial Physician, does the Great Zhou have such medicinal materials?"

Several imperial doctors felt a chill on their necks and their scalps tingled as they said, "I have never heard of moonflowers. Where did Miss Yang hear about these rare flowers?"

"This is a poisonous grass that grows in the desert Gobi of the Western Regions. The flower is shaped like a crescent moon and it blooms only in the middle of the night when there is moonlight. It receives the light of the moon, so it is called the Moon Flower."

Yang Yufei explained in a gentle voice, "The Western Regions are thousands of miles away from the Great Zhou, and few people bring the highly toxic Moon Flower Pollen to the Great Zhou, so it is normal that the imperial physician does not know."

Li Hexiong couldn't stand her showing off and couldn't help but question her, "Since it's a very rare poison, even the imperial physician doesn't know it, how did you recognize it, Yang Yufei?"

"Could it be that you had someone bring back the pollen of the Moon Flower from the Western Regions?"

Yang Yufei knew that Li Hexiong's hostility towards her would not disappear. She said patiently, "This subject accidentally obtained a medical book that had been lost for hundreds of years. I also learned this knowledge from the medical book."

"Your Highness, rest assured. I don't have the ability to reach into the palace."

Li Hexiong was so upset that he wanted to tear Yang Yufei's mouth apart.

This bitch was obviously trying to make things difficult for her, always bullying him in her words and deeds.

What the prince asked was also what the emperor wanted to know, "Yang Yufei, then tell me, how did this deadly poison get into the palace?"

"I don't know. Although the Moonflower is a poisonous weed, the toxins are stored in the leaves and juice, while the pollen is not poisonous. However, some people are severely allergic to this pollen, which can cause breathing difficulties, nausea, coma, and even cardiac arrest in severe cases."

Yang Yufei thought for a moment and continued, "The person who attacked the emperor must have used the Moonlight Pollen to test the emperor before, and confirmed that the emperor was allergic to this pollen, but it was not too serious, so he dared to smear the pollen on the dragon throne without scruples."

The emperor carefully recalled his physical condition over the past few days. "Since the day before yesterday, my throat has been itchy and uncomfortable. I might have had blisters at that time, but they were not serious and have gone away."

Yao Mingjin spoke at this time, "Your Majesty, although the Western Regions are far away from the Great Zhou Kingdom, the Western Regions and the Great Mongolia Kingdom are neighbors. There are always caravans near the border traveling between the two countries. The Great Zhou Kingdom and the Great Mongolia Kingdom are also neighbors, and there are business and trade exchanges. The pollen of the Moon Flower may have been brought to the capital without anyone noticing."

As for poison, although many people try to avoid it, it has great value in the eyes of some people.

"Ministry of Personnel, investigate this thoroughly for me. You must find out who poisoned me. I will make sure he dies without a burial place."

The emperor's face turned pale and veins bulged on his forehead. Who wanted his life? Was it some ambitious minister who thought he was in the way, or was it his sons who thought he had lived too long and was preventing them from ascending the throne?

The prince is the biggest suspect!

The emperor's gaze, as if filled with poison, fell on Li Hexiong, as if he wanted to see through him.

Li Hexiong was so scared that he could hardly control his expression. He clenched his fists tightly under his sleeves, not daring to show any guilt or flaws, for fear of arousing even more suspicion from the emperor.

The emperor stared at the prince for a long time, but didn't see anything unusual from him, so he turned his gaze to Yang Yufei.

"Yu Fei, you did a great job today and saved my life. You have done a great deed. I will reward you with five hundred taels of gold, two paintings by famous artists, and ten rolls of silk and satin."

Yang Yufei was indescribably happy after being cleared of suspicion of murdering the emperor and obtaining a large sum of gold.

"Thank you for the reward, Your Majesty. I am honored."

"I have another request. You take out the medical book that has been lost for hundreds of years and let the people in the Imperial Hospital keep it and study it carefully, so that they won't be at a loss as to how to deal with emergencies. Are you willing?"

Yang Yufei said politely, "Of course I am willing. It is a great merit to be able to pass down a long-lost medical book and save more people. I will take out the medical book when I go back and ask the imperial doctors to copy a few copies so that the knowledge in it can continue to be passed down."

Although she agreed readily, she had already cursed the emperor harshly in her heart.

The bad man had a very good plan. He took away her only medical book for five hundred taels of gold and two calligraphy and paintings. This deal was too good to be true.

Such a life was really too depressing. The royal family forced her to buy and sell things, but she didn't even have the courage to resist.

If she was unwilling, the entire Yongning Marquisate might be executed, and she couldn't afford to offend him.
