After rebirth, I married the emperor's uncle and overthrew my ex-husband's kingdom

"It must be something related to her life, property, or wealth."

Lu Zhenguo's deepest impression of Old Mrs. Qiao was the incident of Bai Yanlang taking a concubine. Old Mrs. Qiao used both soft and hard tactics and was very good at manipulating people's hearts.

Come to think of it, being able to sit on the position of a first-class marquis's wife as the daughter of a fifth-rank minor official requires some skills, and she will not be able to control others.

"I ordered someone to check on Madam Zhang's children. Everything is normal in their family, and nothing strange has happened."

Xu Lingyun was puzzled. "What did Qiao use to threaten Zhang Momo? She would not give in even if her life was sacrificed."

Two major mysteries trapped the two men, and Lu Zhenguo was also a little confused.

"It's impossible for firewood to appear out of thin air in Qingcheng Mountain. I will send people to continue looking for it along this clue."

The pine nut cake in the food box gradually became cold. Lu Zhenguo knew that the woodcutter could not get any useful information, so he said hello to Xu Lingyun, strode out of Jingzhao Prefecture, and rode to Yongning Marquis Mansion.

"Big brother."

Mrs. Lu was already a mother of two children, but when she saw Lu Zhenguo, she still smiled sweetly like a little girl.

"Mom made pine nut cake for you."

Lu Zhenguo handed her the lunch box in his hand and said, "I was delayed on the road. Eat quickly or it will get cold soon."

"It's so cold, why are you bothering this god?"

Mrs. Lu was holding a food box, smiling so hard that her teeth were showing.

The method of making pine nut cake is extremely complicated. The ingredients must be prepared three days in advance. The pine nuts must be peeled one by one, ground into powder, and finally kneaded and beaten with glutinous rice flour over and over again to create a chewy texture.

Whenever she wanted to eat it as a child, the old lady would always take the trouble to make it for her personally. Even after she got married, she would still have someone prepare it and send it to her every year.

Lu Zhenguo looked at his only sister lovingly, and patted her head as he did when they were little, "If you like it, mother never feels tired."

Hearing this, Mrs. Lu felt a lump in her throat and her eyes turned red.

Seeing that she was about to cry, Lu Zhenguo quickly changed the subject, "How is Youyou today?"

"It's gotten better in the past two days. The wound has scabbed over and it doesn't hurt as much anymore."

Mrs. Lu thought of her own daughter and felt helpless. "She just doesn't like to take medicine. I always have to watch her. I'm afraid that if I turn around, she will pour it out the window."

Lu Zhenguo laughed, "I'll go see her."

Bai Youyou was staring blankly at the top of her head at this moment. She had been thinking about this and that over the past few days, and always felt that she had forgotten something extremely important.

She racked her brains, sorting out her memories over and over again, trying to find some clues.

"Youyou, your uncle is here to see you."

Mrs. Lu came in carrying a food box, followed by the burly Lu Zhenguo.

"uncle."

Bai Youyou was about to get up, but Lu Zhenguo quickly stopped her, "Uncle is not an outsider, there's no need to be polite, just lie down."

Lu took out the pine nut cake from the food box and fed a piece to Bai Youyou's lips. "It's still warm. Eat it while it's hot."

Bai Youyou took the pine nut cake and took a bite, a light sweetness spread on her tongue.

She remembered this taste; it was the specialty of the original owner's grandmother and they could eat it once a year.

Lu Zhenguo sat on the chair that Lu had brought over. He looked at Lu and said, "Do you know what disputes or secrets there are between your mother-in-law and Aunt Qiao?"

Lu blinked her eyes, then thought carefully for a moment, and then shook her head, "Since Qiao came into the mansion, the old lady has exempted me from the morning and evening visits. I only go there once during the holidays, and we don't interact much."

When she first joined the Yongning Marquis' Mansion, old Mrs. Qiao had set many rules for her, both explicitly and implicitly, but they were all resolved by Yang Momo.

Ever since the incident with Aunt Qiao, Mrs. Qiao knew she was in the wrong and rarely bothered her.

"Uncle, has Lord Xu found out anything about Zhang Momo's children?" Bai Youyou asked while eating pine nut cake.

If Aunt Qiao threatened Aunt Zhang with her children, it would be understandable that Aunt Zhang would refuse to give in.

Lu Zhenguo shook his head, "Lord Xu said everything is normal and there is nothing wrong."

Bai Youyou paused while eating the cake, "Then what did Aunt Qiao use to threaten Zhang Momo? Have you found out?"

She frowned.

What kind of leverage does Aunt Qiao have on Zhang Momo that she would rather risk losing her head than protect Aunt Qiao?

And Mrs. Qiao is not a good person. It is impossible for her to take such a big risk to kill someone just to silence her niece.

what exactly is it?

Bai Youyou frowned in thought.

Just at this moment, Xiaoju came in with the freshly boiled Chinese medicine, "Miss, the medicine is ready."

Lu took the bowl from her hand, sat on the edge of the bed, and stirred the dark medicine in the bowl with a spoon.

Bai Youyou felt that the strong smell of Chinese medicine made her want to retch. She held her breath to calm her churning stomach.

Xiaoju looked at her distressed look and said, "If only the doctor could make this medicine into pills, Miss would suffer less."

Bai Youyou was just about to open her mouth to drink the medicine when she heard Xiaoju's words and a memory suddenly flashed in her mind.

She pushed away the soup spoon handed to her by Lu and looked at Xiaoju with bright eyes, "Xiaoju, what did you just say?"

"what?"

Xiaoju was a little confused.

"I asked you what you just said."

"I said that if the doctor could make this medicine into pills, you would suffer less."

Xiaoju repeated what he had said before, and Bai Youyou finally remembered something.

Perhaps, Aunt Qiao was the old Qiao who was threatening her with that incident.

She jumped out of the bed, and Mrs. Lu exclaimed, "Oh, be careful, don't let the wound split."

Bai Youyou looked at Lu Zhenguo excitedly, "Uncle, send someone to Jishidiang to check the pills that Yongning Hou usually takes to see if there is anything fishy about them."

"Why are you checking your uncle's pills?"

Lu Xiudou's brain didn't work at all at this moment. Instead, she advised: "Although the pills are easy to swallow, they are not as effective as freshly brewed medicine. Don't be afraid of the hardship. Mom will give you some fruit to press it down."

Lu Zhenguo was shocked when he heard this. "Are you saying that there is something wrong with the pills that Yongning Hou took, and the problem lies with Old Qiao?"

"pretty close."

Bai Youyou didn't say it that absolutely. After all, nothing is 100% certain.

The book wrote that the tonic pills that Yongning Hou took every day were tampered with by someone, and that person was his stepmother.

Aunt Qiao might have used this incident to threaten old Mrs. Qiao, so old Mrs. Qiao had to ask Nanny Wang to kill Zhang Momo and clean up the mess for Aunt Qiao.

"Send someone to check on Wang Momo's son to see if there is anything unusual."

"You mean..."

Lu vaguely understood what was said and her eyes widened in shock.

She lowered her voice and said slyly, "My evil-hearted mother-in-law poisoned the pills of Yongning Marquis?"

"It may not be poison. It is possible that something was added to the pills, causing the medicinal properties of the pills to conflict with each other."

Lu Zhenguo looked at his sister who couldn't keep her mouth shut with a serious look, and warned her earnestly: "Don't tell anyone about this before I find out the truth!"
