On her wedding night, she went into exile with her pharmacy arsenal

The Eighth Princess was surprised. She didn't expect that in such a short time, and this was only the second time they met face to face, Yan Ruyu could see so much.

"What else?" she couldn't help asking.

Yan Ruyu said, "Your Highness has found out that the Ninth Princess has not been in good health since she was born. The Emperor Dacheng has spent a lot of effort to find a famous doctor and treat her."

"Diseases that are acquired from the mother's womb are congenital. They are not completely incurable, but most can only save lives. The possibility of a complete recovery without any sequelae is very low."

Yan Ruyu looked at the Eighth Princess and said, "This princess knows a little about the art of medicine. From what I have seen, you don't look like someone born with a disease. Although you are very thin, you are in good spirits."

The Eighth Princess clenched her fists silently: "What about her? She is aggressive, scolding and beating people, nothing is left out. Does she look like she is sick?"

"She really doesn't look like that, so I didn't think about it in that direction at first, until today."

"Today?" The Eighth Princess was puzzled and frowned in thought.

After a moment, she seemed to think of something.

Yan Ruyu observed her expression and nodded slowly: "It seems that you have thought of it."

"What was that?" the Eighth Princess asked. "She said at the time that someone wanted to harm her, and Tang Yibai guessed that it was your people who did it. But later her face condition was visibly getting better. She didn't say anything, and Tang Yibai didn't say much either, so I didn't bother to ask any more questions."

"It is indeed a poison, but the effect is short-lived and will not kill you. The wound will heal slowly and will not leave scars."

"However," Yan Ruyu paused, "that kind of poison, besides looking scary, will also make you itch uncomfortably."

When the Eighth Princess heard the last sentence, her expression changed slightly.

"My subordinates once said that she didn't realize she was poisoned at first. It was only after you reminded her that she realized there was something wrong with her face. She picked up the mirror and realized what was going on."

"That kind of poison should itch uncomfortably. No one needs to remind you. Once it takes effect, everyone will know it. But she didn't know it. Why is that?"

Yan Ruyu was confident and determined: "If I guess correctly, her illness should be the inability to perceive. To put it simply, she has no perception, no feeling of pain, no feeling of itching, and no feeling of anything."

The Eighth Princess' breathing became a little faster and her lips trembled slightly. She wanted to say something but ultimately did not utter it. She closed her eyes and nodded vigorously.

Yan Ruyu felt relieved after receiving a positive response.

This conclusion was actually based on a lot of guesswork. After all, she had never seen this kind of disease since she traveled through time.

I have seen one in my previous life. He was a man. He was born after birth. Not only did he not feel pain, he also lost all feelings and a lot of happiness.

Over time, the psychology becomes distorted, and people start to harm themselves and kill others.

Yan Ruyu made this bold guess after hearing Yinding's words that he had investigated the situation in the post station.

She looked for the silver ingot to verify it again. When verifying it, she met Song Ping. Song Ping also mentioned that when he went to the inn, he had a conflict with the maid and beat her.

She was beaten and hurt. If she was an ordinary little girl, even if she was Linlang, she should show pain even if she didn't accept it.

But when Song Ping thought about it carefully, he realized that the maid was angry the whole time and wanted to kill someone, but she did not show any pain because of her injury and her movements were hesitant.

One suspicion and two pieces of evidence led Yan Ruyu to make this bold judgment.

The spoiled and unruly maid is the Ninth Princess Dacheng.

Otherwise, no master would allow his maid to be so arrogant, and no maid would dare to be so presumptuous and ignorant of etiquette.

Unless, she has always been spoiled and doesn't need to know any etiquette. She feels that it is natural for everyone to make way for her and pave the way for her.

The eighth princess opened her eyes and her mood recovered a little.

"Since Your Majesty already knows, what are you going to do? Kill me?"

She lowered her head and looked at a ring on her hand.

The ring is inlaid with a ruby, and you can tell it's worth some money, but you can also tell it's a bit old and the style is old-fashioned.

"It's better to kill me. I can then send a message to my mother in her dreams, asking her to live well and stop worrying about me."

"I don't want to kill you, I want to make a deal with you," Yan Ruyu said.

The Eighth Princess was surprised: "Transaction, what transaction? I have nothing, the only identity I have is fake, and you have seen through it."

Yan Ruyu asked: "What on earth do you want to do by exchanging identities like this?"

The Eighth Princess sniffed: "This decision was made by the Ninth Princess herself. I don't know either."

"What do you mean?" Yan Ruyu thought for a moment, "When did she start exchanging identities with you?"

"As soon as you leave the palace, or as soon as you leave Dacheng?"

"After we left the capital, we had more troops with us, so we sent some of them to the edge of the capital, and then we returned to report."

Yan Ruyu asked again: "What about Tang Yibai? Did he agree? Did he just let you guys mess around?"

"Commander Tang knew about this, of course. He didn't disagree. He just said that for the princess's safety, it would be a good idea to have a substitute."

The Eighth Princess laughed at herself: "A substitute. In the eyes of others, I am either a placeholder or a substitute. No one cares who I am. They only care whether I have some value."

She pursed her lips, looked up at Huo Changhe, and her gaze fell on Yan Ruyu again.

"The prince and princess came to me and killed me immediately after failing to see through me. Isn't it because I still have some value?"

Yan Ruyu frowned slightly: "Don't be so self-righteous, and don't be so sarcastic in front of me. You are indeed unfortunate, but your misfortune has nothing to do with me. If you have the ability, resist. If you don't, just bear with it."

The Eighth Princess blushed and choked up, "I don't want to do anything for anyone. I just want to live a good life with my mother, even if it means leaving the palace."

Yan Ruyu said: "What you said before is right. You do have some value. If you can maximize your value, your wish is not impossible."

The Eighth Princess' eyes widened: "Really?"

After saying that, he became a little discouraged: "How is it possible? My mother is in the palace, and the palace is heavily guarded. How can I rescue my mother?"

Yan Ruyu said firmly: "That's not your concern. Just tell me, do you want to cooperate and show your value?"

The Eighth Princess still had some brains and did not agree on impulse. She still retained her rationality.

"What do you want me to do?"

Yan Ruyu asked, "You don't know what the so-called identity change is, but you should know something about what they are secretly planning, right?"

The Eighth Princess pursed her lips and thought: "They don't have many opportunities to meet privately. In the past, Tang Yibai had to hide his identity in the team, and he rarely got together with her."

"However, Tang Yibai did have other things to do. I heard that he resigned from his position as general and stayed in his father's study for a long time. When he came out, he became the commander. Not long after, it was reported that the two countries wanted to make peace with each other."
