The principle of extracting penicillin from the soil system is: first collect a large amount of penicillium, to put it bluntly, it is the mold produced by rotten steamed bread and fruits. Then use rice juice as the culture medium, implant Penicillium into it, and culture for 7 days.

Then, the culture medium is filtered through a filter cotton. After filtration, canola oil is added to dissolve the lipid-containing substance.

Since penicillin is water-soluble, the water underneath the oil dissolves penicillin. Add the water to the activated charcoal, put it in a container and stir. After washing with distilled water, then infuse with vinegar to make acidic water, alkaline seaweed juice.

At this point, filter cotton can be added to the outlet under the container to reduce the flow rate and filter again.

The last and most difficult step is to obtain staphylococcal culture media from the patient.

Apply the different divisions to staphylococcal Petri dishes. After a few days, if the staphylococci only grows around the penicillin applied, then the division is considered effective.

No staph bacteria?

It's okay.

On the whole point of the patient's boo, the cultivated penicillin was dripped in, and the effect was the same.

Wait seven days. Seven days later, there was no mold in the center of one of the dots inside, but there was one around it, and it was done. Penicillin becomes a dish! Buddhist nun! West! Forest!

succeeded the first time, and the most exciting person was Lin Qingqing.

But they didn't rush to use the medicine on Ye Shu, but tried it on a tuberculosis patient first.

Penicillium drugs have up to 90% curative power for diseases such as tuberculosis, but I don't know if the drugs concocted by the local method can achieve such an effect.

"Tell me immediately if there is anything uncomfortable," Lin Qingqing repeatedly admonished.

Before taking the drug, you should know everything, and the patient is nervous and waiting for the result.

Mr. Jing, who was completely reduced to a foil, took the patient's pulse, recorded his pulse carefully, and let him rest when he was done.

That's five days.

Mr. Jing pushed open the door with the pulse case and rushed to the people inside: "...... It can be mass-produced. ”

Lin Qingqing was overjoyed, and took the pulse case to take a closer look.

She has been reading medical books recently, and she has learned a little basic, and it is not a problem to read the pulse case at all.

The joy on her face deepened, and there was a smile in her eyes, and she said, "It's light." ”

"Stop!" Lao Jing's face was full of excitement, "This person has coughed up blood for several months, chest pain for several years, and he has been terminally ill, even it is difficult for me to heal, I didn't expect ......"

He sighed, "The princess's medicine only lasted five days, and he was half better." ”

"This is not my medicine," Lin Qingqing returned the pulse case to him, "I just know, and it depends on you how to get it later." ”

Lao Jing became excited again and said, "Don't worry, it will never be buried." It's just that the princess told me about the person who made this medicine, and when I talk about it in the future, I will also have a purpose. ”

Lin Qingqing smiled awkwardly: "I don't know." ”

Lao Jing did not give up: "What did the princess see in that ancient book?" ”

Lin Qingqing can't let this doctor who is a little dead eyed with professional skills look for him in the sea of books, right?

She still said, "I forgot." You can afford this name, so don't ask. ”

"How's that going to work?"

Lao Jing can't do anything to rob other people's merits. Ask him to give penicillin a name, and he won't do it.

Then it's called penicillin.

"The ...... of the Princess"

The patient waited at the door, stepped in, and knelt down in front of Lin Qingqing, "The princess saved my life, great kindness, the villain has nothing to repay, please accept my three bows." ”

How's that going to work?

Lin Qingqing hurriedly dodged away and went around to help him, "Hurry up." Originally, I asked you to test the medicine, and I can't talk about kindness or gratitude. ”

"It's a trivial matter with the princess, different from me," the man cried and had to worship.

*

It's night.

The pain that was difficult to eliminate made it difficult for Ye Shu to sleep peacefully.

He dreamed again.

I dreamed that the boss was back.

Her voice, the touch of her fingers touching his forehead, and her gaze, Ye Shu was all clear, and he said a lot of words.

When he opened his eyes and saw the light of day, he found a note next to his pillow, and he knew that Lin Qingqing was really back, and he was not dreaming.

"Boss !!"

Ye Shu was overjoyed, jumped off and ran out.

Ye Jingtian, who was guarding the side, didn't have time to put down the book, and hurriedly chased after him, "Shu'er! ”

How can you run like this if you haven't recovered from a serious illness?

Ye Jingtian called Steward Hu: "Hurry up and stop him." ”

Ye Shu pushed the old Hu who was in the way away, "Where's my boss?" ”

Boss, boss, look for the boss as soon as you open your eyes. Ye Jingtian rolled up the book in his hand, put his hand behind his back, pulled his face and told him, "The woman is gone again." ”

Ye Shu's face turned cloudy and excited, "Why don't you stop her?" ”

Why did Ye Jingtian stop it?

He didn't want to upset his son, so he said, "Let's see what message she left for you." ”

Ye Shu had read it just now, and now he picked up the rice paper again and looked at the short lines on it.

"Take your medication on time and get well sooner. Wait until you get back to normal."

The familiar font sent a warm current through his heart, but it wasn't enough to make up for his anxiety that he hadn't seen her in days.

"Didn't you say how many days you would come back? Why didn't you wake me up? ”

"The son of the world is burning so badly, he's talking nonsense," Steward Hu said.

"Then you can't wake up?"

Ye Shu didn't want an answer, he was just angry, and without waiting for others to answer, he walked out of the door with a note.

"Hurry up and persuade the prince to come back!" Ye Jingtian stomped his feet.

"Hey," Steward Hu chased after him to persuade him, saying, "That medicine is difficult to make, and the princess can be busy, if the prince passes, she will have to take care of you." ”

Ye Shu was wearing a middle coat and stopped under the moon cave door, "Did you see her?" ”

Steward Hu nodded: "The old slave is very tired to see the princess of the world." ”

"If I go to her, will I make trouble for her?"

He actually heard the meaning of the words!

Steward Hu didn't expect it, so he nodded quickly.

Ye Shu's impatient face was a little more melancholy, looking at the shadow wall, he felt that he could see her when he walked out.

"The next time she comes back, you'll have to wake me up even if I'm dead!" Ye Shu walked back.

Don't trouble her.

Make her feel good about him.

Understand her.

Listen to her and never quarrel.

Ye Shu had already figured it out, and he knew that she wouldn't leave, and he knew that she would always come back. So he can always restrain his mood these days.

"Old Hu," Ye Shu turned his head to look at the door of the Moon Cave, "I miss her." ”

"The old slave knows," Steward Hu's eyes turned red, almost overflowing with tears, and muttered, "The old slave knows." ”

Not to mention this time, even if it was the last time, why he was so sad, he could see it with long eyes.

……

Just outside the shadow wall, Mr. Jing quietly looked at the person who was engrossed, "Really don't see the son of the world?" ”

Lin Qingqing shook his head: "It's better not to see him than to be in danger with me." ”

She said, "Let's go." ”

Mr. Jing felt that Lin Qingqing had really changed. In the past, she was like a mountain elf who couldn't be caught, and ghost ideas came up one after another.

Now, after going through life and death again and again, her aura has been confiscated, and she is quietly interpreting heaviness with calmness.
