Lord Gu quickly bowed and said, "I will thank you on his behalf, Master, for saving my life. I will thank you in person when he wakes up. Please prescribe the medicine."

Seeing his respectful attitude, Li Lang was pleased and said a few more words: "The patient's internal organs have begun to rot. This poison is very potent. If he takes it and rests quietly, he can live for a few more days. If he exerts himself, it will quickly enter his internal organs. After he dies from exhaustion, the outer shell will still be good, but the inside will be completely rotten."

Upon hearing this, Lord Gu's pupils dilated, and he swayed, nearly losing his footing.

Doctor Li hurriedly turned to the table to write a prescription, and then had someone quickly fetch some cinnamon juice to induce vomiting.

The smell in the room was even worse.

Doctor Li went out to personally watch the servant prepare the medicine. After Yelü Xianyong took it, he waited a while and then urged Gu Shiba to take him back.

Gu Shiba advised, "The ban will be lifted in half an hour. Why bother with all this running around? Why not find a room to rest and have breakfast with your wife tomorrow morning? It will also make it easier to see patients."

Dr. Li insisted on leaving.

Lord Gu spoke up: "Eighteen, quickly send Physician Li back, don't delay."

Gu Shiba had no choice but to risk being discovered by the police and send Li Langzhong back to Renhetang.

Doctor Li repeatedly instructed that once Qin Yuan woke up, he should ask her if she smelled that fragrance.

Seeing that Yelü Xianyong had survived, Lord Gu was relieved. Since it was getting light, he decided not to sleep any longer and went to the outer courtyard to practice martial arts for a while. When he saw that it was about time, he went to Wutong Garden to wake Qin Yuan up.

The inner room was quiet and empty. Through the red gauze curtain, Qin Yuan's sleeping face could be seen faintly. Her long, shiny hair flowed down, covering her jade-like shoulders, and was tightly wrapped in the red gauze quilt.

Lord Gu was stunned.

He often heard his sixth brother mention the beautiful crabapple blossoms, but he just thought it was a literary trick.

Now, seeing her like a sleeping crabapple awakening in the morning light, petal by petal unfurling amidst a rich fragrance, I immediately felt a deep sense of aptness.

He coaxed softly, "Yuan'er, get up quickly. Your master came last night and asked if you could make a kind of incense to save people."

Qin Yuan, her eyes blurry, asked indistinctly, "Who's injured? What illness does he have?"

Lord Gu didn't call the maids in, but took it upon himself to choose a dress and accessories for Qin Yuan and helped her change: "It's Yelü Xianyong. He was poisoned by a poison from the northern frontier called the Gobi Scorpion. Last night, his master prescribed medicine to prolong his life, saying that if he's lucky, he'll slowly recover."

Qin Yuan understood: "He wants incense to help with detoxification and recuperation."

"Yes, can you make the fragrance he wants?"

Qin Yuan frowned: "I've never heard of this Gobi Scorpion before."

Lord Gu said, "My master said this poison is extremely potent. It will deteriorate the internal organs. It will slowly take effect if you rest, but it will take effect very quickly if you move around. After you die from exhaustion, you may look fine on the outside, but your internal organs will be completely ruined inside."

At this point, his thick eyebrows pressed down on his narrow eyes, and his expression was quite different from usual. Qin Yuan assumed he was worried about Yelü Xianyong. After thinking carefully, she said, "There is a recipe for an antidote, but I don't remember it all. It should be included in the dowry."

"That's good. Do you want me to help you look for it?"

Gu Jinghui breathed a sigh of relief.

Qin Yuan sighed: "No need, you go and do your thing. It's just that even if I find it, I don't know if it's the right one, since I've never heard of this poison before."

Gu Jinghui reassured him, "We should try anything, even if it seems hopeless."

Before they finished speaking, Qin Yuan was dressed and urged to wash up by Lord Gu. Only then did she call someone in to serve her. Hongye was on duty today.

Hongye covered her yawn, tears welling up in her eyes, and asked softly, "Why are you up so early? Is something the matter?"

Madam Gu never set rules, and Qin Yuan always managed to linger as long as she could.

I had a few drinks last night, so I should definitely get some more sleep.

Qin Yuan said, "Someone is sick and we urgently need to find a fragrance formula. We'll have to search through the dowry chests later."

Hongye gave an "oh" and quickened her pace, splashing water and instructing the small kitchen to prepare breakfast to serve the Marquis's wife.

Upon receiving the news, Cui Ming and the others did not come in to serve. After having their own breakfast, they went to the council courtyard to handle daily affairs on behalf of Qin Yuan.

After the meal, Qin Yuan took Hongye to the storeroom, brought out the two boxes of books that came with her dowry, and began to look through them one by one.

She has had a photographic memory since childhood, and she knows every recipe for incense by heart.

The fact that Dr. Li told her to make the incense clearly meant he believed she could do it.

She had never even heard of the Gobi scorpion, so the Chen family must have a recipe for an antidote. She just didn't know which book it was in; perhaps she had missed it when she was young.

The two searched carefully, but still couldn't find it.

Qin Yuan frowned, deep in thought.

Hongye said, "Why don't we take all these books out and put them in the study, so we don't have to rummage through the box every time we need them?"

Qin Yuan thought for a moment and said, "No, I'll keep it safe."

Hongye added, "Why don't we put some sachets that repel insects and dampness? It would be such a waste if they got eaten by insects and were left unattended in the storeroom."

Qin Yuan picked up the book and casually squeezed the pages and spine, intending to see if it had been protected against insects, but found that the spine seemed to be thicker than usual.

Having lived an extra life, Qin Yuan's eyes lit up; there was clearly something inside.

"Then go and find some sachets, I'll look around here some more."

Qin Yuan pushed Hongye aside, pulled out her hairpin, and with the tip slightly lifted along the spine of the book, she tore out a piece of yellowish soft silk.

The soft silk was folded in half, rolled into a thin roll, and stuffed into the spine of the book. When unfolded layer by layer, it was as long as a quilt.

The material is light and thin, puncture-proof and tear-proof, as if it were covered with gold leaf, making it a true treasure. It is covered with tiny characters.

Qin Yuan folded it up, tucked it into her sleeve, and went to check other books.

This time, another smuggled item was found, and when opened, it turned out to be a family tree.

Qin Yuan's eyes immediately welled up with tears.

In her past life, she tried every means to find the whereabouts of the Chen family, but now she found them effortlessly.

Before her death, her mother told her to carefully preserve the dowry she was left to her, especially the medical books, which were the Chen family's heirlooms and should never be lost.

She carefully put it away after reading it, never expecting that there was something more to it than met the eye.

Hongye came in carrying a bamboo box, took out a sachet containing medicinal powder and a cloth bag containing wood ash, and placed them mixed together in the book box.

Qin Yuan lowered her head to hide her chaotic thoughts and said casually, "That's right, we'll air out the books again next year when we find a suitable time."

Hongye asked, "If we can't find the recipe, should we still make incense?"

Qin Yuan wanted to be alone for a while so she could examine the roll of soft silk more closely, so she said, "Let's try to make a concoction. If it works, great. Even if it doesn't, we've done our best."

Hongye went about her own business, while Qin Yuan stayed in the small room of the incense room, fiddling with the incense-making tools, and ordered everyone not to disturb her without reason.

She wiped the table clean before taking out a soft cloth, spreading it out to examine it.

The above contains the Chen family's secret recipe that was not passed down to them.

The term "not to be passed down" means that it is only passed down to sons and not to daughters, and is not passed on through marriage.

If there are no men, the tradition will end here.
