Li Yi nodded and immediately ordered the servant to bring the things.

It happened that Xiaohui did not throw away the needle directly, but put it in the box. Now when he opened it, he saw that the silver needle that had not changed color at the beginning turned black at this time, which surprised Li Yi.

"What's going on? I clearly remember that I put it in the box after cleaning it." Xiaohui said in surprise, unable to believe his eyes.

Xiaohui looked at the needle in the box in surprise, because he knew that it was not poisonous when he was setting it up, so he cleaned up the silver needle so that he could use it next time. Who would have thought that when he looked again, he found that it had turned black.

"This means you are that dish, very toxic, and it's useless even if you have washed it." Lu Yanqing said slowly, reaching out to hold the needle in his hand, then turning to ask Xiaohui: "Did all the lost dishes use this needle?"

"yes."

"Then it's hard to determine which dish is poisonous? Xun'er opened the needle bag and saw what changes were."

Lu Mingxuan nodded and immediately did what she ordered. She opened the cloth bag again and found that the silver needle inside had not changed at all.

"It seems that I have to wait. Now it has been confirmed that the food the prince ate is poisonous, but it is this poison. It seems that someone has tampered with it and cannot detect the toxicity inside, but it will be displayed after a long time. Of course, this time may be too long and no one cares about it, so the prince's test was ineffective at that time." She continued to analyze, thinking in her heart what kind of poison would have this effect.

Sure enough, after reading so many books, does she still have a blind spot? Sure enough, she still has to continue to study hard.

Li Yi nodded. He never thought that this was the result, but this also proved that Lu Yanqing was really amazing.

"It turns out that someone really poisoned me. To put it this way, when I was sick, it was indeed a sudden incident and suddenly fell ill. But if I think about whether I had eaten something strange at that time, I really couldn't answer."

After all, it was all a lot of years ago, and he never cared about these things at that time, so he couldn't answer Lu Yanqing accurately.

"It's okay. Since I already know that someone is indeed poisoning the prince's food, I will always find the source. Then the prince should pay attention to his diet. Although I know that it may be a little difficult for the prince now, I still have to avoid it. If there is really no trustworthy person around the prince, I will leave my little apprentice here to serve the prince, and I can also find out who is drugging the food in your hands." She looked back at Lu Mingxuan and gave her a positive look.

"This..." Li Yi hesitated a little, not knowing the reason why he did this. According to friendship, the two of them should be considered a chance meeting. He didn't know why this young lady suddenly cared about him so much?

Lu Yanqing probably saw what he was worried about, so he smiled faintly and said without caring: "Your Majesty, don't worry about my intentions. I am a doctor, you are my patient, that's all. If the Youth is dissatisfied, you will pay the medical fee there."

"I am so cheerful and I am a little restrained. I would like to thank you. I am ashamed to say that I have been so many princes and have been the prince. I can't find a second person I trust around me."

"The prince doesn't have to say that. In fact, it's the same. Although he is a young lady from the prime minister's house, his situation is not much better than that of the prince." How many people are there in the so-called family that she can trust?

Suddenly, in this regard, the two of them really felt the same.

"From the future, Xun'er will stay by the side of the palace Ye. Although my little disciple has all his personalities, he has a lot of skills to take care of the prince's food and clothing. This is because of this personality. He is a bit erratic. Please forgive me, but he is simple. If she offended the prince, he will just tell me." She continued, she was not afraid that the child would be bullied at all in the palace. As long as she did not bully others, it would be a blessing.

"Since he is the apprentice of the eldest lady, he is the guest of honor for me, and he is also my junior. I will take care of her." He looked up at the girl standing next to Lu Yanqing, with a hint of gentleness in his eyes. He didn't say a few more words since she entered the door, but he was unexpectedly obedient.

If she is her apprentice, she should be a good child.

"Your Majesty, you will regret what you said today." She couldn't help but rub her forehead, and she promised that this girl would make trouble here in the royal palace.

"Master, are you praising me?" Lu Mingxuan was beside him, and when he heard it, he couldn't help but curl his lips. He felt that the master was not praising her. She knew that the master liked the first brother, not her.

"Of course I'm praising you. Okay, let's not talk about this anymore. Prince, let's have a meal."

After she finished speaking, she picked up the chopsticks and prepared to pick up the food, but was stopped by Li Yi.

"Didn't the young lady say, are these dishes poisonous? Why are you picking up dishes? Let's take them down." He couldn't help but frown. Wasn't she afraid of being poisoned?

He was already so miserable that he could not let the person who wanted to save him be poisoned.

"If you don't eat it, you will be suspected. Don't worry, my prince. I am a body that is invincible with all poisons. These poisons will not work for me. As for you, you have been infected with so many poisons anyway, and you don't care about this meal." As she said that, she grabbed a piece of meat and put it in her mouth. I have to say that the taste is still OK.

Li Yi was a little laughed when he heard this, and he was like this, so why bother to care about this?

After lunch, the two of them didn't talk for long, so Lu Yanqing got up and went home, but this time he did not take Xun'er back with him.

Ruoer had questions in her heart, but she didn't know how to ask.

As soon as she returned to the prime minister's mansion, she was called away by her father. Lu Yanqing felt a little depressed. Why did her father ask her to go over to do this at this time? Could it be because of the matter of her going to the Yong Prince's Mansion today? She was thinking about it in her heart, but when she got there, she heard that what her father told her was the prince's business.

"The prince will hold a banquet tomorrow. Please invite you to the prince's mansion to gather. You can also perform well at that time."

Lu Yanqing was a little stunned. He looked at his father who didn't know how to speak. The prince held a banquet for her and asked her to perform well. What does this mean? Is the prince really interested in her and wants her to marry her as the princess? When she thought of this, she felt a little resistant.
