After transmigrating into the book, I helped my mother reconcile with her divorced husband.

At the Marquis's residence, Lu Zhiyuan removed her hand from Old Madam Lu's wrist and looked at Lu Huai, who was waiting to the side: "Grandmother is not ill, she is poisoned."

"Nonsense! How could your grandmother be poisoned out of the blue?" Lu Huai flicked his sleeves. "I don't know how you fooled the Emperor, or how you convinced Imperial Physician Jiang and the other physicians in the palace of your medical skills. I'm reminding you, don't implicate the Marquis's mansion."

"Father, rest assured, it won't implicate the Marquis's mansion. Yuan'er hasn't even been added to the family genealogy yet."

One sentence left Lu Huai speechless.

Lu Zhiyuan examined the old lady's eyes: "The area under her eyes is light blue, the poisoning is not severe, there is still hope."

"You really can save your grandmother?" Lu Huai stared intently at her. "She's your own grandmother; you can't afford to do anything reckless with her!"

“Look at what Father is saying. How could I be like Father, treating other people’s lives like dirt?” Lu Zhiyuan shook her head seriously. “If you want to treat them, then treat them. If not, I’m leaving. There are thousands of people outside the city waiting for me to save them.”

Lu Huai asked with a puzzled look, "You grew up in a separate courtyard, when did you learn medicine, and who taught you?"

Lu Zhiyuan rolled her eyes, took out a silver needle, and, ignoring Lu Huai's objections, pierced a certain acupoint on Old Madam Lu: "I learned my medical skills from my master, but as for who my master learned from, I don't know. My master has already passed away. Why don't you ask him for me when you get to the underworld?"

"Lu Zhiyuan, are you cursing me?"

“I’m just telling the truth. Do you think Father wants me to die before you? I’m so kind, I’ll be reincarnated sooner, but I still won’t be able to answer your questions then.” As she spoke, she inserted another silver needle: “Grandmother’s poisoning is related to the cup of tea she drank yesterday. Please bring the teacup, I want to test the poison so I can prepare an antidote for Grandmother.”

"What teacup are you referring to, Miss?"

“These are the teacups that Aunt Ji served when Mother and Father divorced.” Lu Zhiyuan said calmly, “There were many things to do yesterday, so Grandmother and Aunt Ji temporarily moved to Fangfei Courtyard. These teacups should not have been washed yet.”

Before he could finish speaking, Lu Huai rebuked, "Nonsense! How could Wanwan poison her mother?"

“Yuan’er didn’t say that!” Lu Zhiyuan pulled out the silver needle. “That tea was originally prepared for Mother! Instead of getting angry here, Father, you should ask Aunt Ji for the antidote. Grandmother is old and can’t take any more trouble.”

The images flashing through his mind reminded him that what Lu Zhiyuan said was true. Clenching his fists, ignoring the butler's advice, Lu Huai rushed out of Fulin Courtyard.

Lu Zhiyuan watched coldly and handed the silver needle to Liu Ying.

"Uncle Jiang, let's go!"

"Ji Wanwan, is that the woman Lord Lu brought back from Weinan? She wants to turn your mother into a fool?"

"Hurting others will only harm yourself in the end." Lu Zhiyuan blinked: "Uncle Jiang, you don't need to take her to heart."

Physician Jiang didn't care about her; he harbored murderous intentions towards Ji Wanwan.

At Fangfei Courtyard, Ji Wanwan put down her snacks and went to greet him: "Brother Huai, you're back? Wanwan has been waiting for you."

Lu Huai grabbed her by the throat: "Tell me, why did you poison Xie Chaoyun?"

Ji Wanwan was in great pain and struggled, saying, "Brother Huai, what are you saying? Wanwan doesn't understand. My sister has already left the Marquis's mansion. What does her being poisoned have to do with Wanwan?"

Lu Huai pressed harder: "What did you put in that cup of tea? Do you know what Mother...?"

Ji Wanwan was being choked and couldn't breathe. She could only grab Lu Huai's hand and say, word by word, "What's wrong with the old lady?"

Lu Huai first pushed her down, then grabbed her again: "What do you think happened to your mother? Ji Wanwan, your mother has treated you well, how could you just watch her drink that cup of tea?"

"What tea? Wanwan doesn't know!" Ji Wanwan took a deep breath, her throat aching with each breath: "Brother Huai, you're going to strangle Wanwan... What can't you say to Wanwan properly?"

Lu Huai let go and sat down on the ground with a dejected look on his face.

Ji Wanwan got up and moved to the side with lingering fear. She controlled the distance very well; too far and it would seem awkward, too close and it would be like putting her neck in his hands.

"Yesterday, when Xie Chaoyun and I were divorcing, what did you put in the tea you brought us?"

Ji Wanwan did not answer. She first looked to the side and, seeing that the maids and servants were far enough away, then said, "The medicine was bought by Wanwan from the ghost market by the old lady. She said it could make people stupid and easy to control."

His pupils dilated suddenly, and Lu Huai stared directly at Ji Wanwan: "Did your mother ask you to buy this? When?"

Ji Wanwan was startled and couldn't help but swallow hard: "A few days ago."

Lu Huai smiled bitterly: "Am I still the Marquis of Pingnan? Do you even respect me as your Marquis? Xie Chaoyun requested a divorce behind my back. You and Mother plotted poisoning each other behind my back as well. If I die one day, will I be nothing more than a clueless, confused ghost?"

“Huai… how could you think like that, Lord Marquis?” Ji Wanwan grabbed his arm. “The old lady and Wanwan are both thinking of the Lord Marquis! The old lady saw through my sister’s thoughts long ago and knew that she was determined to divorce the Lord Marquis. The Marquis’s mansion is in dire straits and needs to use my sister’s dowry to help. Lord Marquis, you must understand the old lady’s feelings.”

Lu Huai closed his eyes: "How did you get to the Ghost Market?"

Ji Wanwan pursed her lips: "Wanwan has kept the Marquis's reminder in mind and has not left the manor. In my early years, Wanwan struggled to make a living and often went to the ghost market, so I know some secret codes. The medicine was delivered by them, and Wanwan specifically asked them to make sure it wouldn't harm anyone."

Lu Huai looked at her, his eyes reddening: "But it will turn people into idiots!"

"Becoming an idiot is better than losing my dowry!" Ji Wanwan couldn't help but raise her voice: "Has Your Excellency forgotten what our original plan was?"

Lu Huai was taken aback and looked at Ji Wanwan's resentful eyes.

"Does the Marquis care about my sister?" Ji Wanwan cupped his face in her hands. "The Marquis said he would make Wanwan the mistress of this manor, that he would let Wanwan take over the dowry, and that he would make Wanwan the most prominent noblewoman in the capital. The Marquis also said that he only has Wanwan in his heart, and Wanwan only has the Marquis in her heart. What is the Marquis doing now? Is he blaming Wanwan?"

Lu Huai waved her hand away: "I did say those things, but I never said I wanted to divorce her."

"Exterminating the entire Xie family is tantamount to killing Xie Chaoyun! The Marquis has the resolve to kill her, but can't bear to see her become an idiot?" Ji Wanwan laughed, shrugging her shoulders. "The Marquis is no longer the same Marquis he once was! The Marquis has fallen in love with her!"

"I didn't!" Lu Huai's eyes widened in fury. "What I care about is that you hurt my mother!"

"Wanwan didn't!" Ji Wanwan argued, "The medicine was ordered by the old lady. Wanwan was just following her instructions to bring the medicine to my sister at the right time and try to get her to drink it. Wanwan never expected that my sister wouldn't even give me that little bit of face and would embarrass me in public. Wanwan also drank the tea, but Wanwan doesn't know why the old lady wanted to drink it. In the end, it's just harming others and herself."

"Shut up!" Lu Huai glared at Ji Wanwan: "Guards! Ji Wanwan is plotting to harm the old lady. Drag her to the dungeon! We'll deal with her after the old lady wakes up."
