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

Liu Ying whispered, "We didn't offend Manager Lu."

Shopkeeper Lu quickly explained that the matter had nothing to do with Lu Zhiyuan, but was because his daughter's illness had caused his wife to lose her composure. He blamed himself for being useless and could only watch helplessly as his daughter died.

Shopkeeper Lu's daughter, Lu Xuan, suffers from tuberculosis, which is similar to but also different from Lu Zhiyuan's. Lu Zhiyuan's tuberculosis was caused by pneumonia resulting from a persistent high fever in her childhood, while Lu Xuan was infected with tuberculosis by someone who had it.

Both pneumonia and tuberculosis were difficult to treat in ancient times. There were some folk remedies, and some of them were effective. However, patients could not try them all. If they tried the wrong ones, it would worsen their condition or even lead to death.

Shopkeeper Lu's wife wanted him to plead with the Marquis's mansion so he could get his hands on the blood-soaked buns. These blood-soaked buns were a folk remedy for tuberculosis. Shopkeeper Lu refused, which led to the sound of hitting him earlier.

"I am not very talented, but I have become quite knowledgeable about medicine due to my long illness. I would like to take a look at Sister Xuan'er," Lu Zhiyuan said. "Even if I cannot cure her, I can still report her symptoms to Physician Jiang. With Physician Jiang's diagnosis, Sister Xuan'er's illness will surely improve."

Manager Lu's eyes lit up, and he knelt down and kowtowed several times.

Lu Xuan was very ill, her body skeletal, seemingly on her deathbed. Fortunately, she had a strong will to live, and she was willing to try anything, even if it seemed hopeless.

"Liu Ying, go buy medicine!" Lu Zhiyuan examined Lu Xuan's tongue and found pus and blood that she hadn't coughed up at the base of her tongue: "Peony bark, gardenia, lotus root, Imperata root, trichosanthes root, anemarrhena rhizome, glehnia root, ophiopogon root, quick!"

"What medicine did you prescribe for my Xuan'er?" Manager Lu's wife pushed her away: "You're so sick, how dare you prescribe medicine for my Xuan'er? Do you want to kill her and drag her down with you?"

Liu Ying helped Lu Zhiyuan up and shoved the shopkeeper's wife: "My young lady kindly saved your daughter, and you are so ungrateful! Do you know that the last person who cursed my young lady has a grave covered in weeds?"

“Liu Ying!” Lu Zhiyuan stood up and helped the manager’s wife up as well. “She is different from those people. She just loves her daughter dearly, just like a mother loves me. Don’t worry, Madam, the prescription I gave to Sister Xuan’er is for treating tuberculosis. Madam, you can let Manager Lu come along. I don’t mind.”

"You're not lying to me, you really will save my Xuan'er?"

She clung to Lu Zhiyuan's arm as if it were her last straw. Lu Zhiyuan struggled a few times but couldn't break free, so she could only whisper words of comfort and make repeated promises. The shopkeeper's wife, completely exhausted, ignored her daughter's frail health and sat on the ground, wailing loudly.

Afterwards, Lu Zhiyuan learned that Lu Huai had promised Manager Lu one tael of silver per month for Lu Xuan's medical treatment and medicine, until Lu Xuan recovered or passed away. When Lu Jingyuan was born, Lu Huai gave the rouge shop to Ji Wanwan. From that year on, Manager Lu never took that one tael of silver again, and even his own salary was repeatedly delayed by Ji Yaozu until the rouge shop closed down, and they still held Manager Lu responsible for this debt.

The small walnut was lost by Manager Lu when he was being beaten in the shop. The person who beat him was none other than Ji Wanwan's younger brother, Ji Yaozu.

If we're talking about profiting from human suffering, then Ji Yaozu and Ji Wanwan were the ones who truly profited from human suffering.

After taking one dose of medicine, Lu Xuan finally stopped coughing and was able to get a short, peaceful sleep. Returning with Liu Ying were the pharmacy manager and the attending physician. The manager wanted the prescription from Lu Zhiyuan. A shrewd businessman, he immediately recognized that this prescription was unusual; it was a targeted treatment.

Tuberculosis is divided into four stages: initial stage, abscess formation stage, suppuration stage, and recovery stage. Having run his pharmacy for many years, he had never seen a patient in the recovery stage, but he had seen one in the suppuration stage. Patients in the suppuration stage have very obvious symptoms: coughing up large amounts of purulent, bloody sputum, resembling rice porridge, with an unusually foul odor. Occasionally, they cough up blood, experience chest fullness and pain, shortness of breath preventing them from lying down, fever, flushed face, and a strong urge to drink water.

Doctors commonly use drainage therapy to detoxify, but there are many medications available, making it difficult for doctors to decide which to use and which to avoid. Using too little medication may be ineffective.

Overdosing on medication can be fatal to patients.

The prescription given by Lu Zhiyuan included peony bark and gardenia for the patient's hemoptysis, trichosanthes root for thirst, and astragalus root to replenish qi and promote pus drainage. The efficacy and dosage of the medicine were just right.

Lu Zhiyuan had no interest in the pharmaceutical business, and finding the prescriptions useless, she made a deal with the pharmacy owner. She asked him to provide Lu Xuan with a cure. The owner was more than happy to oblige; in his eyes, Lu Xuan was an excellent trial subject. If her tuberculosis could be cured, his pharmacy would soon become famous throughout the land.

Having resolved Lu Xuan's matter, Manager Lu's brows relaxed considerably. Lu Zhiyuan invited him to return to the shop as manager, but Manager Lu hesitated, neither agreeing nor refusing.

“Miss, I am a member of the Lu family. You bought the shop without the Marquis’s knowledge. Aren’t you afraid that I will expose this to the Marquis?”

"I'm not afraid, because Manager Lu has a scale in his heart, and knows which way the weight should fall." Lu Zhiyuan twirled her fingers: "You are an elder of the Lu family, and you should know my situation. In the eyes of my grandmother and father, I am someone who could die at any time. Although my mother is the mistress of the Marquis's mansion, she has too many things she has to do. I took over this shop behind the backs of the Marquis's mansion and my mother, also to prove that I, Lu Zhiyuan, am not useless."

Manager Lu sighed: "I understand what Miss is saying, but we still need to carefully consider the matter of launching a new type of rouge."

There are only a few types of rouge on the market, and most of what's sold in the capital is also these. How to make new rouge? What about the cost? These are all things that need to be considered. In Manager Lu's eyes, no matter how smart or business-minded Lu Zhiyuan is, she's still just an eight-year-old child.

An eight-year-old child is bound to make mistakes in his thinking. As the manager of the Lu family, he has a responsibility and an obligation to remind him.

When asked about labor and costs, Lu Zhiyuan simply replied, "I've saved up quite a bit of money over the years. If it's not enough, I just borrow from my mother and uncle."

Manager Lu smiled, slightly embarrassed.

Lu Zhiyuan is not Ji Yaozu. Behind her are not only the Hou Madam, who is good at business, but also the Xie family's eldest son, who is even more good at business.

The Xie family's businesses are spread all over the world. Let alone a rouge shop in the capital, even if they were to flourish everywhere, it would only take a word from the eldest son of the Xie family.

Lu Zhiyuan's business wasn't a traditional cosmetics shop, but rather an ancient-style studio integrating makeup and personal image design. Besides traditional purchasing services, she offered free trial makeup and free makeup services. If a customer was satisfied, they could upgrade to VIP status, receiving a complete personal image design and a portrait created to commemorate their needs.

For distinguished guests who are unable to leave their homes, personalized in-home and full-service makeup services are available to ensure their convenience and privacy. In addition, she had Amber purchase a more private residence near the cosmetics shop to provide figure shaping, language training, and intensive courses in music, chess, calligraphy, and painting for wealthy ladies who wish to enhance their personal charm.

Lu Zhiyuan wanted more than just money; she also wanted to get involved with the various social circles and powerful figures behind these women. She wanted to entangle the Xie family with their interests.
