Back in the courtyard, Van Yan saw Xing Mai sitting in the hallway cutting the fabric, looking at her, sighing for a moment.

Xing Xing saw Valjen come back, hurried up, took over the hedge, looked at Valjen's face, heartbroken, “Are you tired? If you return to your home in a few days, there will be a lot fewer people looking for you. ”

“Well, Sister Xing, help me with the bath soup, I want to take a bath.” Valentine.

Xing Ma smiled. “It's time to take a bath and get sick. ”

It was not long before Valjen recovered, which was already empty. On this day, two patients were diagnosed and two bodies were dissected. Some of them could not be eaten.

Soaking in warm water, Valjen is a little sleepy.

“Ma'am, Xing sent slaves to wait for you to bathe.” There was a crisp sound outside.

Yan Yan is not used to someone watching him take a bath beside him, but this time he's too tired to let the waiter help him wash his long fucking hair, he said, "Come in. ”

The visitor dressed Valjen in the morning with a small bathtub with a wooden lid, hidden heat in the crevices and a floral fragrance scattered through the air.

“What is it?” Van asked.

Xiao Man knew that Van Yan wasn't as scary as he looked on the surface. He smiled shallow and blossomed out the little wine cave on his cheek. “Slaves saw the golden and silver flowers in the yard and picked some to bathe for the woman. It's good to bathe with the golden and silver flowers in the summer! ”

Valentine nodded, but thought to herself, when Xiao Song really guessed correctly, Feng Chun is probably drowned in the bathtub, but... Whose bathtub is she drowning in?

Xiao Manmei saw that Valjen had not spoken and dared to go forward, “Madam, would you like to wash your hair? ”

“Okay.” said Valjen.

Little Manchu pulled a tall stool from the corner of the wall, placed it by the tub, and then placed it on top.

Watching the small, full motion, her pupils shrink sharply - the bench! Wooden barrels!

This tall bench in the bathroom is a little rough, but it looks a lot like the one that fell under the feet on the day the green was hanged at night. The Tang Dynasty still sat in sitting. The case numbers are very low. The seats with legs similar to the chair bench have only a hammock, and the hammock is far less tall.

Also, this barrel cover...

“Mandy, you stand opposite me.” Valjen slowed down.

Xiao Man was pouring petal bath soup into the bathtub. When she heard that Valjen remembered her name, she answered with joy. Happiness placed the remaining half barrel of water on the high bench beside the bathtub and stood opposite her as promised.

Valjen reached out of the tub, touched the little wooden bucket, and poured all the water into the tub. And then I started studying the barrel body of this barrel, and the barrel cover, and from time to time, I took these two things and I drew them over my head, and I looked at the bottom of my heart for a while, and I was afraid she was really throwing them on my head.

This barrel has a narrow, narrow mouth, but it is very heavy. It will not just swell on the head, whether it is the bottom or the mouth. At least it will break the skin. The wound on the spring head is arcuate and should be caused by this barrel lid.

The barrel was of different sizes and different radians. Jomo's killer hurriedly threw the barrel cover onto the spring surface and immediately found that she was not dead or fainted...

Valjen stood up from the barrel, reaching out and holding Little Full's neck.

Little stared at the convex body of the face, the skin like sheep fat jade with a bright light, stood in the smoke, it simply snatched the soul.

She was looking straight into the gods, but her neck was grabbed with a brazen face. She poured the edge of the bathtub and her face almost touched the water. She shouted, “Mother, forgive me! Mother, forgive me! ”

Valjen looked back and found herself standing naked in the bathtub, coughing awkwardly, sitting silently back in the water, explaining to her full of unsettled surprises, “I... just thought of something. ”

When I heard this explanation, Xiao Man didn't worry about it at all. Thinking about something, I took the barrel lid and slapped her in the head again, and then tried to push her into the water again?

But... the woman has a really good body! Little Spirit of Water's eyes glanced at the hidden body in the water and whispered, “Ma'am, the slave washes your hair. ”

Valentine nodded her head. At this moment, she figured something out. She stopped flirting and let Xiaoman brush her hair over her waist and hips.

After a long bath, Van Yan immediately went back to the room to grind the shape of the bathtub and the look of the high bench. Then he wrote a letter to Zheng Yang Yong, the guard of the Zhuang Zi, to send someone to Liu Shishi immediately.

After doing all this, Valjen really relaxed. After dinner, she went to accompany Green for a while and went back to her bedroom to rest.

Perhaps tired and harsh, this night's dreams, although fragmented with many images, were never connected, but it was the best time to sleep in six or seven years.

Over the next few days, the rain continued and the trip was very inconvenient. The people who wanted to see Valjen were sending letters saying that they would not dare to ask her to come to the door herself and bring the patient to the door on the agreed date.

So these days, Van Yeung was idle. After seeing the patient every day, she went to see Wu Xiu and there to talk to him about medical treatment. Since Van Yeung cooked that meal, Wu Xiu and obviously worked harder and harder than before. Sometimes she insinuated that she should cook a meal and work hard.

Five days later, penicillin is almost ready to be extracted.

Valjen pours the liquid from the thirty dishes into a pre-prepared special wooden barrel, then injects the vegetable oil into the barrel and mixes and stirs.

Penicillic water contains a lipid-soluble substance, and the oil dissolves to separate this lipid-soluble substance. After stirring evenly, wait still.

Ultimately, the material in the barrel is separated into three layers, the first layer is the fat-soluble material dissolved in oil, the second layer is the insoluble substance insoluble in water and insoluble in oil, because penicillin is a water-soluble substance, so it is sunk in the water at the bottom.

It looks like a barrel underneath a special wooden barrel, with a plug pulled out, the water at the bottom slowly flowed out, and Valjen sanitized it into a porcelain bowl with wine and distilled water.

After filtering some of the large impurities, pour them into the jar, which contains crushed carbon that has been cooked and disinfected, and after stirring, penicillin is absorbed by carbon.

Xing Ma, who helped her beside her, looked at Valjen and poured out a pile of bottle jars. I don't understand how it would make a difference if a bucket of mold was added and the water was placed for another seven days?

In fact, today's operation of these steps is not difficult at all. The preparation of these materials is difficult. Even disinfection of alcohol and distilled water leaves Valjen tired and tired every day. Especially the collection of distilled water. Although not difficult, the quantity is small. Collecting a bottle takes a lot of time, and when disinfection, the vast majority of bottles are poured all at once. It is simply the sweating of the face!

There is also the sodium carbonate needed for filtration, commonly known as alkali and soda, to be made from salt, sulfuric acid, coal and limestone as raw materials. Fortunately, Van Yeung followed the chemist's father for several years, otherwise only knowing the method of extraction of penicillin can dry eyes.

Valjen stirred the carbon and water soluble matter evenly before purifying it three more times. Added separately: distilled water, small soda water, weak acid water (vinegar + water).

The first universal addition of distilled water filtration, the poured water is not a penicillin solution and can be discarded.

Second, weak acid water was added and the filtered water was still thrown away.

Step three, add the small soda water and the filtered solution is the real aqueous penicillin solution.

Valjen looked at the four bottles containing the aqueous penicillin solution, she had always calmed down, her eyes slightly reddened - it was so hard! These days, she was tired of distilled water alone, and her back ached.

When I thought about seeing syphilis on Purple Ox, Valjen didn't think much about it, because as a psychologically modern person, a modern medical scientist, subconsciously thought that the penicillin extraction procedure was a relatively simple thing, but I really didn't know until I did, Tang Dynasty had no soda, no distilled water, fine carbon had to be milled slowly by itself, the medium solution had to be boiled with potatoes and rice by itself...

How could Da-dung get such a nasty disease? She exclaimed in her heart that if she could change it, she would prefer to dissect two bodies a day and would never want to make penicillin!

“Ma'am, is this the fairy water?” Xing asked softly.

After a moment of vanity, I remembered that when I said that there was a point in my dream, I had to nod my head.

Two drops of Staphylococcus aureus were poured into the other dish. This species is better obtained. A little bit of it was discovered a few days ago, and it was placed in the culture solution to promote its growth. Today, it is full. Staphylococcus aureus fades with the infusion of aqueous penicillin, and the infusion is quickly emptied.

Validation works. Valjen was completely relieved. If this last step proves ineffective, then she really is going to cry. Fortunately, the heavens have not treated her harshly.

Valjen carefully put away these hard-earned bottles of penicillin and finally put down a big stone on his mind. In a relaxed mood, he decided to cook a meal for the cheap master.

Wu Xiu and Baba stretched their necks and waited for half a minute. Valen had just finished the first dish, and Valen Yunsheng arrived. His old man, angry, blew his beard, bitterly maintained fairy wind tunnel bones, instantly the land collapsed, sprinkled and cheated, everything was extremely necessary.

In despair, he had to make his favorite East Slope meat, one meal at a time, to comfort his broken heart.

Van Yunsheng smiled like a flower, “Yan, your master is really interesting. ”

Her lips bent slightly and she didn't answer the question. She asked, "Are you done? ”

“You forgot?” Wen Yunsheng stopped, "it's the Seventh Evening Beggar Festival! How could you forget that as a daughter's family? ”

“Oh.” Van remembered Xing's hasty nagging since the early morning.

“Come on, let's go freshen up. We're going to the Ping River tonight, and the uncle wants me to take you there too!” Van Yunsheng hurried. (To be continued. If you like this work, you are welcome to vote on recommendations, monthly tickets (qidian.com), and your support is my biggest motivation.)
