Hiding her pregnancy and divorce, she stopped licking and the general panicked

Someone said with pity: "Doctor Su, this pus is contagious, you can't touch it."

"Yeah, others don't even have time to hide..."

Su Yujiao said indifferently: "I know it's dangerous, but someone has to do the dangerous things."

Wearing a mask, gloves, cotton swabs and a porcelain bottle, Su Yujiao went forward to collect some pus and sealed it in the porcelain bottle.

Lu Ziqian said, "I'll go to the front room and light a Cangzhu cigarette."

After disinfecting themselves, the two men changed into clean clothes they had brought with them and hurried back to the city.

County Magistrate Zhang was already waiting at the gate of the courtyard, which was the place specially provided for her to develop the cowpox vaccine.

"Have you prepared everything I need?"

"It's all here. Doctor Su can check it again."

"Ah."

"Okay, let's all move in."

"No one is allowed to enter this yard after I go in."

"Also, prepare some things for me. Here's the list. Just leave it at the door. I'll take it myself when everything is ready."

County Magistrate Zhang took a look at the list and became even more confused. Moldy oranges, rice washing water, rapeseed oil, and charcoal blocks?

Are there cows that are irritable, have a loss of appetite, have red eyes, and are skinny?

This, this, this, what this young doctor wants is always so unexpected.

"Doctor Su, what do you want these for?"

"To develop medicines, of course."

"You don't need to ask too many questions. Just prepare according to the list. Make sure there are plenty of moldy oranges."

"Oh, by the way, please send the items on this list as soon as possible. They are all very important."

"Especially spirits, please send as much as you can. Once made into alcohol, it can be used for disinfection and cooling."

"The most terrifying thing about the plague is the persistent high fever caused by the lesions. As long as the fever can be reduced, it will be much easier to treat."

Just as Su Yujiao finished her instructions, Gu Heng arrived, exhausted and dusty: "Brother Su, be careful."

"I'll have someone guarding outside the courtyard. If you need anything, just shout."

"Thank you, Brother Gu."

Before Su Yujiao entered the courtyard, she glanced at Lu Ziqian, who warned her worriedly, "Be careful!"

"Even if it doesn't work, you have to save your life."

Su Yujiao looked at him deeply, feeling indescribably complicated. He was nice to everyone, but he was so cruel to her.

Seeing her staring at him with a complicated look, Lu Ziqian asked in confusion, "What's wrong?"

"Or, you should wear this mask!"

The woman shook her head and calmed down: "No need."

"I'm going in, you all take care of yourselves."

After Su Yujiao went in, she cut many small wounds on the udders of the two cows.

Then apply the viral pus to the wound. Just wait for 5 days and the virus will reach its peak growth.

Then disinfect the affected area and use a scraper to scrape off the scab and dermal tissue from the wound.

This sticky substance is the original vaccine solution, which is then diluted with water, dipped with a cotton swab, and applied to the nasal cavity of the vaccine recipient.

The vaccine recipient will have a fever within one to three days, and the vaccination is considered successful after the fever subsides.

Just as Su Yujiao finished all this, Magistrate Zhang's voice came from the doorway: "Doctor Su, everything you want is ready."

"Okay, I'll get it later."

After finishing the work at hand, Su Yujiao moved the moldy oranges into the yard in baskets.

Then apply the fermented rice water evenly on each orange. The purpose of this is to allow the mold to quickly and evenly cover the entire orange.

She only had to wait seven days to get a spore culture of Penicillium.

The spore culture is then fermented in rapeseed oil. After seven days, charcoal blocks can be used to separate the oil and water. The separated water-like liquid is the penicillin concentrate.

While waiting for the butter vaccine and penicillium, she was not idle.

Instead, jars of liquor are distilled into alcohol.

In the blink of an eye, five days passed, and Su Yujiao successfully extracted the original liquid of cowpox vaccine.

She first vaccinated herself in the courtyard, and then developed a fever the next night. She took the antipyretic medicine prepared in advance, and kept wiping herself with alcohol to reduce the temperature physically, and the fever subsided that night.

On the third day she was full of energy. It's good to be young. After working non-stop for five days, her resistance was still very strong.

Outside the city, Chen Yunniang and her servant finally arrived in Qicheng under the escort of Liu Wu.

Chen Yunniang said that she was Lu Ziqian's family member, and the guards on the city wall went to inform Lu Ziqian.

Lu Ziqian sent someone to bring the person to the city.

"Where's General Lu?"

The soldier who came to pick you up answered truthfully: "General Lu is busy and cannot come to pick you up in person."

"The general asked me to take you to a place to rest."

Chen Yunniang shook her head: "I'm not tired, I don't need to rest."

"Give me a brief overview of the city's situation, and I'll go help later."

"Yes."

After listening to the introduction, Chen Yunniang specifically asked about Doctor Su's situation. When she learned that Doctor Su was secluded in the courtyard alone to develop medicine, she became interested.

She did not ask where Doctor Su was, but asked him to do something else, saying that she would go to the clinic to help after a short rest.

After the soldier left, she randomly asked a local and easily found out Su Yujiao's location.

"Let's go over and have a look."

When the master and his two servants arrived at the courtyard, it was already dark. Chen Yunniang asked Liu Wu to climb the wall to check the situation.

"Miss Chen, I have already checked and it is true that Doctor Su is the only one in the hospital."

There was a murderous look in Chen Yunniang's eyes. This bitch had hurt her so badly, she would never let her go.

"Do you still have any drugs on you?"

"Have."

"Sneak into the courtyard tonight and knock her out. That bitch should be pretty. You can do whatever you want to her."

"After that, they stuffed a handkerchief used by a plague patient into her mouth."

"Isn't she an excellent doctor? Let's see if she can save my life."

Liu Wu was still lying on the wall at this moment, looking at Su Yu's delicate and graceful figure, with a lewd smile on his face.

Suddenly, he saw someone coming, so he reminded them and the three of them hid in the dark together.

I saw a man wearing a bird-beak mask knocking gently on the gate.

"Who?"

"it's me."

"Brother Gu, why are you here?"

Gu Heng said with concern: "I was worried about you, so I came to check on you."

"How's the drug development going?"

"Are you feeling unwell?"

"I remember you said the results would be out in seven or eight days..."

Su Yujiao was standing in the yard. There was some distance between them, but one could still tell that she was very happy.

"Brother Gu, I succeeded!"

"I've tried it on myself, and the fever has gone down. Now I won't be infected even if I sleep with someone who has the plague."

"We just need to report this to the Crown Prince. After he experiments on death row prisoners, we can roll it out nationwide."

"Brother Gu, I have made such a great contribution this time, I will definitely be able to rescue my brother."

Gu Heng was happy for her when he saw how happy she was, but he had a little selfish motive for coming here today.

"Jiaojiao, congratulations, I knew you would succeed."
