After my rebirth, I became the Prince Regent's favorite

She said in a deep voice: "Miss Lin, I know that you are young and have self-restraint in medical skills, but you are a little impulsive. My mother-in-law's disease is not even the imperial doctor can do anything about. Even Madam Han who came back from the Medical Valley was invited. , she just kept shaking her head, if you said it couldn’t be cured, I definitely wouldn’t make things difficult for you!”

Lin Ruoyou raised an eyebrow and glanced at her: "I didn't say it couldn't be cured. The reason why I was silent just now was because I wanted to know how to cure it!"

A look of astonishment flashed across Mrs. Shizi's face. She really didn't expect that Miss Lin in front of her had some abilities.

But I still don’t know if her ability is real or she is just bragging.

Lin Ruoyou ignored her scrutiny and quickly stepped forward and called softly: "Old madam, can you hear me?"

The Duke's wife struggled to open her swollen eyelids and rolled her eyes blankly.

But at the moment of turning, Lin Ruoyou could already see the problem.

She said in a deep voice: "Mrs. Crown Prince, on the day when Her Royal Highness the Princess entered the residence to give gifts, were there any outsiders who came to give gifts?"

Madam Shizi frowned, but she couldn't think of anything.

She said helplessly: "There are so many things going on in the Duke's Mansion every day, and my mother-in-law has been ill for more than a month. I really can't remember it. But you can look at the concierge's records. They should remember it very clearly!"

Lin Ruoyou asked her to find the concierge's records and make sure they were detailed.

Soon the mother-in-law sent it in, and Lin Ruoyou lowered her head to check carefully.

Turning to the night when the eldest princess gave gifts, I saw that in the afternoon, Li Jixiangpu sent Dongtan into the house, and there were about five carriages.

Lin Ruoyou raised her eyes and fell on the burning charcoal basin in the room. There were wisps of smoke, which made the whole room extremely warm.

Mrs. Shizi followed her gaze and couldn't help but explain: "Li Jixiang Shop has provided us with spices and charcoal for several years in a row. There has never been any mistakes. Miss Lin has no doubts!"

Lin Ruoyou noticed that when she said this, her face looked a little unnatural.

She asked calmly: "Is it possible that the shopkeeper of Li Jixiang Shop is still involved with Mrs. Shizi?"

Mrs. Shizi froze. She was stunned for a moment before whispering: "To be honest, this incense shop is my natal shop. My father-in-law also knows about this. I have never made any profit from it. I thought that I would have to use charcoal anyway, so instead of giving a lot of money to others, I might as well use my own, and feel at ease!"

She paused, then opened her eyes suddenly and asked, "Is there really something wrong with the charcoal fire?"

Lin Ruoyou spoke slowly: "I have just checked the old lady's body. In fact, she is not sick, but poisoned!"

"How is that possible?" Mrs. Shizi covered her mouth in shock.

After she came to her senses, she quickly said: "Even if it is poisoning, it is because of eating those bird's nests. There is absolutely no problem with our winter charcoal. Don't slander me just to exonerate the eldest princess. I am not that good either." Bullying!"

Seeing her face that was too excited due to anger, Lin Ruoyou's eyes flashed with a stern look.

She said solemnly: "Whether there is something wrong with Dongtan will be known once we check it. No matter how much the Crown Prince's wife denies it, it can't change the fact!"

Mrs. Shizi bit her lip in panic. She really didn't expect that after searching again and again, she would find her own family members.

Seeing that she had calmed down, Lin Ruoyou also slowed down her tone: "Mrs. Crown Prince, for this plan, isn't the most important thing for us to save the old lady?"

"Even if it is really found out that there is something wrong with Dongtan, you were just deceived by your mother's family. If I were you, I would investigate ruthlessly. Ji Guogong is not stupid. He will think that you are selfless, even to save me. A person can even abandon his own family!"

I have to say that these words completely moved the Crown Prince’s wife.

If Dong Tan was really poisoned, Li Ji would never let him go lightly.

Rather than being led by others, it is better to do it yourself, so as to gain a good reputation.

Thinking of this, she felt extremely grateful to Lin Ruoyou.

She stepped forward and held her hand and said: "Miss Lin, thanks to you, I have an enlightenment. You are right. As the prince's wife and the mistress of the Duke's mansion, I should be sharp-minded, no matter what. I can't tolerate whoever wants to harm my mother-in-law, I'm going to investigate right away, and you can go ahead and detoxify my mother-in-law!"

Lin Ruoyou nodded and comforted softly: "I do this because I don't want good people to suffer unjust injustice for bad people. And the poison in this winter charcoal is not ordinary, it is insect poison. It likes to smell it most. I smelled the best bird's nest, so I got into the old lady's body. After all, the person in the dark is also plotting against the eldest princess. When this matter is found out, she will definitely be involved!"

Mrs. Shizi let out a sigh of relief. No wonder the women who were waiting on her were not poisoned. It turned out that the insect poison and the bird's nest complemented each other.

She gritted her teeth and said: "Okay, my cousin must not be able to come up with such a watertight plan. There must be someone secretly instigating it behind the scenes!"

Seeing that she had figured it out, Lin Ruoyou started to deworm the old lady.
