The little girl tilted her head back, and her eyes suddenly lit up.

"Sour mustard greens stew?"

Su Ci nodded rapidly: "Yeah!"

She has been looking for this thing for a long time.

The dish of braised mustard greens may sound strange, but if you use another word, you should be familiar with it: penicillin.

Penicillin is well-known to modern people, but many people don’t know that it is known as the miracle drug of the 20th century. Its appearance ended the era of large-scale deaths. It is the nemesis of many incurable diseases and a miracle in treating infections due to trauma. It has opened the golden age of antibiotic treatment. Anyone who understands the history of human medicine knows what a great invention this is.

It is antibacterial and anti-inflammatory and can treat infections, trauma, and terminal illnesses of the time, such as scarlet fever, diphtheria, syphilis, pneumonia, septicemia, typhoid, etc. If penicillin could have been successfully extracted in ancient times, even if it was just a crude version, it would have had unparalleled therapeutic effects.

Holding this in your hand, no matter where you go, it will definitely be a powerful bargaining chip to make a living.

Su Ci has been thinking about it for a long time.

In fact, she didn't think so much at the beginning. The reason she did this was actually the same as the catgut bending needle. At that time, her family was caught in the center of the political struggle. She was afraid that if something happened in the end, she would have the medicine to save them.

She and Su Yan were sent out, but Su Di and Chen were still inside.

But it didn't work out in the end.

Even if she is a medical student and has systematically studied all relevant knowledge, and because of her family background, she has also dabbled in pharmacology, but with the current level of technology, it is useless to say anything. The equipment, drugs, etc. are not in place. Knowing more theories is useless and it won't work.

For example, in surgery, Su Ci could only perform tendon suturing at most. Major operations such as craniotomy and thoracotomy were simply impossible to complete.

So Su Ci evaluated that what she could accomplish, which was relatively easy to start but had the greatest effectiveness and effect, was to try to cultivate anti-infective toxins.

The reason why Su Ci chose penicillin was because she happened to have citrus peels on hand at the time.

But this so-called easy to get started is only relative. It is not easy at all in actual operation.

Su Ci worked on it off and on for more than half a year, cultivated the bacteria for many generations, and conducted animal experiments, but the results were not ideal at all.

This thing is really not like what is shown in some dramas, where you can just travel back to ancient times and try to make it - for example, the Penicillium that looks exactly the same to the naked eye, in addition to penicillin, there is also patulin. Patulin is more antibacterial than the former, but it is poisonous, and the toxicity is very strong and stubborn.

The original strain is very important. It does not require high yield but must be non-toxic. Nowadays, every company’s mature mother strains are confidential, which shows how important they are. Otherwise, doing this would be just hooliganism. The number of people killed by the treatment would definitely be far greater than the number of people saved. The one person who cannot be killed must have been lucky.

The Penicillium that Su Ci made using citrus peels was not very effective. If she continued to work on it, she might not be able to find a suitable strain in her lifetime if she was unlucky. After the animal experiment failed, she turned her attention to other areas.

Is there a strain out there that she wants?

Most likely there will be.

"Compendium of Materia Medica" says that widow's bedside ash can treat vomiting, diarrhea, muscle pain and abdominal distension. Because the widow's bed was cold and she hadn't moved or wiped it for a long time, a layer of dust accumulated on the head of the bed over time. But in fact, mold loves to grow in dark and damp places.

There is also aged mustard greens stew, which has a long history. The earliest clear record was in the Ming Dynasty, where "Tianning Temple in Changzhou stored mustard greens in large jars, which were placed in the courtyard to be exposed to the sun and rained at night to make the mustard greens moldy and grow long green hairs. The monks then sealed the jars and buried them in the ground. After more than ten years, they were put back into use. This was called 'aged mustard greens stew', which was specially used to treat high fever, typhoid fever, and pus and blood in the lungs, and was very effective."

This is the earliest oral penicillin, much earlier than that in the West.

The former is a bit stream-of-consciousness, but the latter is much more reliable, and Su Ci is targeting the latter.

Su Ci's modern mother and uncle are both traditional Chinese medicine practitioners, and her grandfather is a national master of traditional Chinese medicine. She knew this since she was very young. She also knew that this aged mustard greens stew must have existed among the people for a long time before there were clear records of it.

Although it is a different time and space, it is very likely to exist.

The strains cultivated from generation to generation are much more reliable than those she could cultivate on her own.

It’s definitely not a very productive year, but it’s enough for her and her family to make a living.

Su Ci had thought about sending people out to look for them before. At first, she asked her father to send two people, but later on, there was chaos inside and outside the house, and the two sisters were hiding outside with only Uncle Gong by their side. It was impossible to send more people, so they never found them.

Now, the crisis of the whole family being killed has passed, and Yang Yanzong has handed over his medical camp to her. This is a good opportunity - Su Ci is here, and she doesn't plan to leave. She doesn't want to be a woman who stays in the backyard and gives birth to a child.

Therefore, the demand for aged mustard greens stew becomes necessary and urgent.

Su Ci originally asked her father to give her two more people in two days, but she didn't want to be given a pillow when she was sleepy. Yang Yanzong asked a good question!

His attack was much more powerful than his father's, so she didn't have to think about how to find a needle in a haystack!

"I want to try to make a new medicine." Su Ci originally wanted to say that it would be of great use if it was made, but after thinking about it, she was not even sure if there was aged mustard pickle, so she decided not to say it for now.

Yang Yanzong nodded and asked a few questions about the braised old mustard greens, and he agreed.

"Do you like studying medicine?"

“I guess so. I like studying this!”

The two walked out side by side. They recognized the place. Su Ci didn't have to come here every day. If she wanted to come, it wouldn't be too late tomorrow.

He said a few words of caution in a light tone, and Su Ci understood immediately. It meant that they should keep a low profile during this period. She understood!

"I'll change my clothes and come back another day. It's inconvenient enough to wear a skirt." She can draw inferences from one example.

"Don't be too restrained. Everyone in this courtyard is ours." As for this area, it is the garrison area for his subordinates.

"oh."

Finally, Yang Yanzong glanced at her and said, "The situation is complicated recently. Don't go out unless it's necessary."

Su Ci understood immediately and touched her face.

Well, my beauty is obvious to all!

"I understand. I understand."

Su Ci understood what he meant and was in a very good mood for the moment, which was reflected in the fact that the corners of her lips curled up slightly and her steps became exceptionally light.

Yang Yanzong glanced at the little girl. She was pretty, but there was no need to be so proud of her.

He snorted.

However, I have to say that after spending some time with this girl, my emotions, which had been tense and sharp since entering the city, unexpectedly relaxed a lot.

The person next to him was very petite, only reaching his shoulders. He didn't like her height, but the sunlight shining on her profile was so bright that it seemed to glow.

Starting a family, home is a place to relax, he never thought about it before, but now that he has a real candidate, he thinks it’s not a bad idea.

"I'll take you back."

…

Yang Yanzong sent Su Ci back and immediately left the camp. It was said that this man just came back at midnight last night. People were seen going in and out of the yard next door early in the morning, and he went out again at noon.

Su Di was nowhere to be found. When Lin Yichu returned home, she hurried out with a bag in her hand. She bumped into Su Ci, rubbed her hair, and reminded her, "Don't run around. Auntie and A Yan are in the house."

Chen lifted the door curtain and waved. In the west wing, there were sounds of banging and cursing. Chen pretended not to hear and led her two daughters into the house.

Su Song is sixteen years old this year. He is thin and still a young boy who has not fully grown. However, Lin Yuchu has been following Su's father since he was sixteen years old. But then again, Lin Yichu started out as a soldier. He joined the camp at the age of fourteen, and it was natural for him to be picked out because of his outstanding performance. Aunt Bai didn't want Su Song to be a soldier, and kept delaying it until this year. However, no matter how reluctant she was, she finally had to let her son take on the job of a personal soldier.

So now one of them guards the yard, and the other one follows Su's father to gain experience.

Aunt Bai would express her displeasure almost every day, but Chen and the others were used to it and pretended not to hear it.

Su Yan was forced to learn embroidery on the edge of the kang. After a short while, her fingers were poked with seventeen or eighteen holes. When she saw her sister coming back, she felt like she had seen a savior. She quickly threw the crooked embroidery stand back and came over.

Chen glared at her eldest daughter. Su Yan clung to her younger sister and pretended not to see. Chen was annoyed by her for talking too much. She didn't bother to pay attention to her and stroked her younger daughter's soft hair. "Where did you go in the middle of the day?"

This was not what she wanted to say. Although Yang Yanzong did not enter the courtyard when he sent Su Ci back, Chen still saw him. Both of her daughters were not young anymore. Chen felt a little sad and reluctant: "When we find your uncle and aunt Yang back, you and Dalang should get married."

Su Ci's smile froze, and the tea that she finally drank after several months no longer smelled good.

The two sisters looked at each other and laughed bitterly.

After finally fooling their mother, they no longer had to pretend when they returned to their boudoir. The two sisters kicked off their embroidered shoes, climbed onto the kang, and looked at each other for a while. Su Yan thought about it again and again, and finally sighed.

"Getting married?"

Even Su Yan, after much thought, felt that it was better for her sister and Yang Yanzong not to be together.

The main thing is Ji Chengtan, who is a time bomb.

There was always a feeling that there was something fishy going on. If Ji Chengtan wasn't killed, he would pop up again at any time. Su Yan couldn't guarantee that this problem could be solved silently.

Yang Yanzong is ruthless and not an easy person to deal with.

If the truth comes out, I'll be dead.

Su Ci held her chin with one hand. In fact, she had the same idea.

One has to admit that Yang Yanzong is a man with his own charm, and if nothing unexpected happens he will succeed in the end. His inner and outer qualities are enough to attract countless women to throw themselves at him.

But this does not include Su Ci.

This is not just any high mountain, it is simply Mount Everest. She has no hobby of climbing mountains. Her first wish in life is to be an indifferent fish and do some small things that interest her at most.

Once she develops penicillin and her medical science is profitable, she can live a leisurely life and just hitch a ride with the male protagonist on her way forward.

Why bother getting involved in his backyard?

Su Ci felt a toothache when she thought of the hellish love line in the original book. She didn't have the tendency to be self-abuse, so she decided to just forget it.

Su Yan had a headache: "But what should I do?"

Isn't it possible for this to happen even if you don't think about it? It was useless for them to reach a consensus in private, as even Chen was preparing to marry off her daughter.

The two sisters were extremely worried. They closed the door and discussed the matter for half the afternoon, but still came to no conclusion.

There's nowhere to start.

You can't be soft or hard, and you can't take the initiative to destroy unity and offend the male protagonist.

Su Yan rakes her hair a few times. She was impatient to comb her hair into a complicated bun. Chen had just combed her hair for her and took it apart when she returned to the room. Now her hair was almost rake into a bird's nest.

“What should I do? What should I do?!” I have no idea at all!

Su Ci did have a little idea, after all, there was the direction of the heroine in the original book. But in the original book, she died, and her death was extremely ignominious, and in the end she was replaced by the original heroine Su Rong.

But she is fine now, and it is impossible for her to die or destroy her reputation just to avoid an engagement. She is not stupid!

Then there is no way to talk about Su Rong's top position.

...makes one bald.

Su Yan got off the kang, ran to the cabinet by the west wall, took out three incense sticks, lit them, bowed and muttered something, then burned incense to the Buddha.

——Since the family encountered a big disaster at the beginning of the year, Su Yan has developed the habit of burning incense to the Buddha. In the end, she believed that the Buddha was still somewhat effective.

She turned around and waved, "Sister, come and burn some incense for the Bodhisattva!"

Su Ci: “…”

Su Ci pretended to be dead, so Su Yan had to take her sister's place. Then she started to chant something, saying that her sister was still young and the Bodhisattva should not blame her, and prayed that her sister would have good luck in her life.

But I don’t know if it was the effect of Su Yan’s chanting, or if it was really a blessing in disguise, but the two sisters didn’t have a headache for long. Not long after Su Yan started to worry about losing a few clumps of hair, the situation really took a turn for the better!
