My Lord, the princess doesn't want you anymore.

Just as Mei Xueer was thinking, the little medicine boy walked in, "Forget your ancestors, just now that villager accidentally injured his foot while weeding with a hoe. The wound was so deep that the bone was visible. Fortunately, the bone is fine. I have sewed it up for him."

Wang Li waved his hand without even looking up, "Got it, you can go down."

How could a ten-year-old child be able to treat such an injury? Mei Xueer couldn't help but look at the medicine boy again.

Wang Li saw Mei Xueer's confusion and said, "This child has been with me since he was three years old. If this minor injury couldn't be treated, I would have driven him away long ago."

Mei Xueer rolled her eyes and said, "Master Wang, I have an unwelcome request. I hope you can fulfill it."

"Girl, please speak."

"I want to be your disciple!"

"Ah..." Wang Li was stunned when he heard this and quickly waved his hands, "No, this is not allowed..."

"Master Wang, don't you believe in my ability? I can do it."

"No, that's not the question... cough... Miss, you have superb medical skills, I don't deserve it." Wang Li hesitated, "And I, I swore that I would never accept another apprentice in this life. So, Miss, please don't mention this matter again."

This guy looked strange when he heard that I wanted to be his disciple. I wonder what's going on?

"...In that case, let's talk about this later." Mei Xue'er was puzzled, but she didn't force it. Instead, she pretended to be nonchalant and asked again, "Just now, Master Wang mentioned the Nanyue Witch Doctor Department. I have heard that the Witch Doctor Department has also developed many insidious poisons like Yi Yan. The most terrifying one is a kind of Gu poison. I wonder if you have heard of it."

Wang Li's eyes gleamed, and when he looked up again, he had regained his clarity of mind, "Of course I've heard that Gu poison can control a person's mind. However, the method of making Gu poison was not lost with the fire in the Nanyue Palace. Because before the fall of Nanyue, the recipe had already been spread out."

Mei Xueer felt her heartbeat speeding up, "How did it leak out?"

"I'm not sure about this. I heard it, but it doesn't mean it's true. I heard that before the fall of Nanyue, Dazhen sent envoys to Nanyue, and the recipe for the poison was stolen at that time. As for who did it, how can we, the common people, know?"

Mei Xueer felt like her heart was about to beat out of her chest. She took a deep breath and tried her best to appear calm.

Wen Yi once told her that in the secret room of Prime Minister Mei's study, there was a booklet which recorded the method of making poison.

Before the fall of Nanyue, Prime Minister Mei was ordered to go on a diplomatic mission to Nanyue.

Is this just a coincidence?

Impossible! My father was so upright and honest, how could he covet such a sinister and evil way, not to mention taking the opportunity of a diplomatic mission to South Vietnam to risk his life to steal it.

What kind of place is the Witch Doctor Department? It is not an exaggeration to say that its defense is more stringent than that of the Heavenly Prison. If it was easily stolen, then the Witch Doctor Department must have developed countless medicines during the hundreds of years of Nanyue's existence. Wouldn't they have been circulated in the world long ago?

But what about the book in the secret room of my father's study that records the method of making poison? Where did it come from?

Mei Xueer had more and more doubts in her mind, and she was very absent-minded in the following conversation.

After sitting for a while, she stood up and said goodbye. "Master Wang, I still have some things to deal with, so I will leave today. I will not leave Xinglong Town in the near future. If you are free, I will come to visit you later."

It was almost noon, and Wangli did not invite her to have lunch. He just said, "Okay, I'll be at your service anytime."

Wangli stroked his beard and looked at Mei Xueer's carriage thoughtfully. It gradually disappeared in the wheat field. When it was out of sight, he sighed and said to himself, "Do you know why I changed my name to Wangli?"

The little medicine boy who had been standing behind him took a few steps forward and said in a cold voice: "Let me remind you again, it's best to put away your kind heart."

There was no longer the previous caution in his words, nor the slightest respect for the teacher. The look he gave Wang Li became arrogant and cold.

It's like a different person.

Wang Li looked back at him and said expressionlessly, "I have already done what you asked me to do. What else do you want?"

The ten-year-old medicine boy snorted, "Do you think I don't know what you are thinking? I'm telling you, don't think that this Mei is your savior! It's fine if she obeys me, but otherwise I will kill her right away."

At this point, the little medicine boy looked at Wang Li with contempt, "As for you, if I want you to die, it would be as common as stepping on an ant."

In the carriage, everyone kept chattering.

This trip opened their eyes. They had always thought that the princess's medical skills were unique in the world, but unexpectedly, there was someone as good as the princess.

"If you ask me, that genius doctor is still not as good as the princess. Our princess is still young. If she reaches his age, she will definitely be better than him."

"Our princess is more powerful than him now, okay?"

"What are you talking about? Our princess will never grow old."

"Of course. What I mean is that, decades later, the princess's medical skills will be even more invincible, and her appearance will naturally remain the same as it is now."

"Then he would become an old monster."

"Hey, have you seen those medicines? I heard that the prince was also looking for that thing called fire-dried seeds everywhere, but he never found it. I didn't expect to find it here."

"What prince or no prince? Where did the prince come from..."

"I deserve to die. Let's not mention the dog prince. Let's not mention that ungrateful stinky man."

…In the midst of the noise, only Mei Xueer remained silent. No, there was also Wen Ding.

[Goudan, I always feel like something is wrong! ]

Goudan: [You mean, that little medicine boy? ]

Mei Xueer nodded: [You noticed it too? ]

Goudan rolled his eyes, which Mei Xueer could not see: [I am not a fool. If he developed early, reached puberty early and his voice changed, this is too early.]

Mei Xueer: [There is something wrong with Wang Li who seems to answer all my questions. He seems to be reminding me to pay attention to the medicine boy all the time.]

Goudan: [In short, this trip is full of weirdness. Woman, you'd better be careful and cautious. Don't lose your life and kill me at the same time.]

"Stop the car!" Mei Xueer suddenly spoke, her breathing a little unstable.

Wen Bing quickly stopped the carriage, and everyone suddenly shut up because the princess looked very unhappy.

"Miss, what's the matter?" Nanxing asked.

Mei Xue'er didn't reply to her, but turned to look at Wen Jia with a serious expression: "Go back quietly and keep an eye on that Wang Li. Be very careful not to let anyone find out. You'd better disguise yourself. Oh, and you should pay special attention to the little medicine boy beside him."

"Medicine boy?"

Mei Xueer closed her eyes and thought for a while before she said, "Just now, the more I thought about it, the more I felt something was wrong. That Wang Li answered everything I asked without hiding anything. And this was only the first time I met him, but he told me all the secrets of the South Vietnam Kingdom without hiding anything. Don't you find it strange?"

Hearing this, Wen Jia also realized that something was amiss. "Also, according to what he said, he is just a traveling doctor. How can he know so much about the Nanyue Witch Doctor Bureau?"

Mei Xueer nodded, "The most suspicious one is the medicine boy. Wang Li always said in front of me that he was a child. In fact, he was not a child."

"But, that's clearly a child, right? Except for the voice." Nan Xing looked puzzled.

"Do you know there is a disease called dwarfism? You are not doctors, so you probably don't know." Mei Xueer said, "This disease is very rare. Some patients with dwarfism, although they are adults and have adult minds, look like children. If Wangli only accepted such a dwarf patient as his apprentice, it would be understandable. But Wangli should have thought that with my medical skills, I might be able to tell that it was a dwarf. However, he emphasized in front of me at least three times that it was just a child. This was a deliberate reminder. And the performance of the medicine boy was a bit too much. An adult pretended to be a child and called 'ancestor' naively. It felt like he was trying to cover up the truth. Also, if he was really a child in his teens, even if he was a genius, he would never be able to treat such a wound for the farmer alone. But Wangli seemed very confident in his medical skills and didn't worry at all... All this was too abnormal. In fact, I don't know if my worries were unnecessary, but I was worried."

"Princess, I understand." Wen Jia jumped out of the car without saying a word, turned around and reminded: "You guys, make sure to protect the princess and Nanxing."

"A, come back!" She lifted the car curtain and shouted.

Wen Jia turned around before he had gone far.

"Remember my words, be careful of that medicine boy." Mei Xueer looked at him solemnly, "You must come back safely."

Thinking of what Mei Xueer had just said, everyone was worried.

"Miss, you told that Forgetful that you would come again after a while. So, shall we come again?" Nanxing asked.

Mei Xueer smiled coldly: "Come! Why not come?"
