Fang Zhengyi walked to the princess's bed again and observed it for a while.
I found that other than a fever and a cough, I couldn't see anything special.
I heard that Dr. Hu said it was a lung disease, and I couldn't help but feel that it looked a bit like pneumonia, but after all, I wasn't a professional medical student, so I couldn't be sure at all.
He could only turn to Li Yuanzhao and said: "Your Highness, let's go. It's useless to stay here, so as not to disturb the princess' rest."
Li Yuanzhao nodded heavily.
The two of them walked outside the palace door. Li Yuanzhao leaned against the pillar depressedly and said softly: "Old Fang, do you know that Miaohan is my dearest sister? We have been together since we were young, and he is one younger than me." Yue has always been frail and sickly."
"When I saw her feeling so uncomfortable today, my heart felt like a knife. I wish I could kill that quack doctor right away!"
Fang Zheng stood aside silently.
Li Yuanzhao continued sadly: "I thought you had many ideas and could find a way to save her... I didn't expect..."
"What should I do if she leaves?"
The two were silent for a long time.
Li Yuanzhao suddenly raised his head and said to Fang Zheng: "Old Fang, do you want a wife or not?"
"???"
Li Yuanzhao suddenly said this, and Fang Zheng suddenly felt that the style of painting had changed too quickly, and his heart couldn't accept it.
"I remember that there seems to be a folk method called happiness. Why don't I marry Miaohan to you and try it!"
"There's nothing we can do about it. It's only okay for you. If it were any other man, I wouldn't agree to it even to the death!"
"Just say whether you are willing or not!"
Fang Zheng raised his head and looked at the sky speechlessly. He married the dying princess to himself. Is the prince treating me well, or does he hate me?
He smiled bitterly and said: "Your Highness, those are all folklore. If Chongxi could cure diseases, there would be no war in this world..."
Hearing this, a string in Li Yuanzhao's heart seemed to be suddenly broken!
He jumped up and grabbed Fang Zhengyi's arms, roaring: "You said it!! Then you say it!! What else can I do!!"
Fang Zhengyi immediately pulled Li Yuanzhao's hand away and shouted: "Calm down!"
"The most important thing now is to find a way to save the princess. Why are you yelling so loudly! Is it useful!?"
Li Yuanzhao woke up from Fang Zhengyi's yell, slumped to the ground, and murmured: "Is there any other way... Is there any other way..."
Seeing his devastated look, Fang Zhengyi couldn't help but feel the same.
The prince is also a sweetheart...
He said helplessly: "Maybe... I have a way... but the hope is very slim."
Li Yuanzhao jumped up as if grasping a life-saving straw, and said excitedly: "Old Fang! You really have a way! Say it quickly!"
"There is something called penicillin, which may be able to save the princess's illness."
Fang Zhengyi also struggled for a long time before deciding to speak out, without any hope in his heart.
Penicillin was a panacea in later generations, a soft gold during war times.
It is extremely safe and plays an immeasurable role in antibacterial and anti-inflammatory effects.
Fang Zheng happened to watch a drama before he traveled through time, which explained in detail the preparation of penicillin through local methods.
But I can only remember the general outline, the details still need to be pondered over.
However, he must ensure that the program is correct, the preparation environment is up to standard, and the knowledge on TV dramas must be reliable... so the success rate is basically zero in his mind.
Seeing the prince like this, he can only act like a dead horse.
"I have a way to get this medicine, but don't say anything until it succeeds. Moreover, it takes time to make the medicine. Whether the princess can hold on before then depends on luck..."
Li Yuanzhao was very excited: "Okay! Okay, Lao Fang, what do you say? I'll find someone to help you!"
.....................
The two hit it off immediately and immediately rushed back to the East Palace and ordered Liu Jin to get some baskets of oranges.
Place all oranges in a dark place to allow mold to grow. Over the course of a few days, mold begins to creep onto the surface of the oranges.
Fang Zhengyi also asked people to get rice and taro to boil into juice, and roughly made a culture solution.
Finally, select the greenest strain of Penicillium on the orange peel and put it on the culture medium.
After a week, the culture medium was almost complete, and vegetable oil was added to it and stirred.
Since penicillin is a water-soluble substance, this step is to continue purification.
Next, add carbon powder and continue stirring to purify.
In the following steps, Fang Zhengyi vaguely remembered using acidic water and alkaline water to further purify penicillin.
I don’t know how to make acidic water, so I can only add vinegar. As for alkali, there is plenty in the imperial kitchen, although the purity cannot be guaranteed at all.
There are several steps to filter in the middle. There is no such thing as filter paper. Fang Zhengyi even brought toilet paper from Taoyuan County from home!
Taoyuan County government-supplied toilet paper is tough and soft, has good air and water permeability, and has a high density, which is much stronger than ordinary rice paper.
Due to the lack of disinfection methods, toilet paper is sterilized by exposing it to the sun when the sun is bright.
The needle tube was also handmade by a silversmith, and the rubber stopper was replaced with animal sinew.
All experiments are being carried out in an orderly manner, and Fang Zhengyi's confidence is constantly being built up through experiments one after another!
In order to ensure safety and rigor, Fang Zheng could not determine the order of the experiments. All test equipment was steamed at high temperature, and the ratio of acid and alkali water was also adjusted in groups. In the end, there were 27 experimental groups!
The prince could only participate in it a small amount of time, because he was scolded by Yan Guoan and Emperor Jing for skipping classes from time to time.
Of course, Fang Zhengyi was also scolded, but this could not stop the two from continuing their experiments.
During the preparation of penicillin, the princess got sick again inexplicably. Fortunately, she survived again without any danger.
finally! Half a month later, all penicillins in all experimental groups were successfully prepared. Fang Zhengyi also summarized a thick notebook, which recorded the experimental processes of each group in detail!
As soon as Fang Zheng looked at the twenty-seven small silver bowls with lids on the table, each bowl contained a portion of penicillin, he couldn't help but feel a sense of pride in his heart!
I took a great step in human history by doing my own experiment for the first time since time travel!
Li Yuanzhao looked at these silver bowls and couldn't help but feel a little drumming in his heart.
I have never heard of such a cure, but Lao Fang is a strange person! Of course there is a reason for this!
Believe him! Believe him!
"Old Fang! What should we do next?"
Fang Zheng said: "Let's put aside whether this medicine can cure diseases. Our top priority is to verify the safety of penicillin. I need some death row prisoners. The rest will be left to Your Highness..."
Li Yuanzhao readily agreed.
I don’t know what method he used, but early the next morning, a thick list of death row prisoners was delivered to Fang Zhengyi.
Fang Zheng looked at the roster, his face getting darker and darker...
At the back of each roster, the crimes committed by the prisoners are recorded one by one, such as murder, arson, and raping women. There are many perverts who enjoy cannibalism and murder.
Twenty-seven people were originally selected for the test, but Fang Zheng kept selecting and selected more than forty people.
I originally wanted to cancel it...but considering the differences between individuals, I finally thought it would be better to select more people to get more accurate results. The princess has no time, and she must succeed this time without failure!
So I hooked up a few more and gathered fifty-four people.
Three days later, there was a dungeon in the capital.
It has been converted into a huge sun-shaped cell. There are oil lamps all over the dungeon, but it still looks a bit dark.
They were separated by curtains. Fang Zheng was worried that the prisoners were too dirty and would spread some bacteria through sneezing and breathing, contaminating the test products.
Since the prince was caught skipping class, Fang Zheng was the only one doing the experiment today.
More than a dozen guards were guarding Fang Zhengyi. In front of him was a large table with twenty-seven silver bowls placed on it.
Fang Zhengyi silently drew the penicillin from the twenty-seven silver bowls into the numbered silver syringe.
After everything was prepared, the curtain in the middle of the dungeon was slowly opened.
More than fifty death row inmates looked at the young man in front of them through the cell door with some anxiety. This was the first time they had such an unusual prison experience.
Fang Zheng said slowly: "Don't be nervous, everyone. The reason why you are gathered here today is to try out a new drug for my Dajing soldiers."
"This medicine can cure hundreds of poisons! It is extremely safe, but you need to tell us your experience after using it."
"The lucky prisoners who come to participate in the experiment today will each receive a reward of twenty taels of silver, which will be distributed after the autumn!"
"After the test is successful, I will plead with the court to exempt you from the death penalty and change it to life imprisonment!"
"Okay, now that I've finished speaking, who is in favor and who is against?"
As soon as Fang Zheng finished speaking, all the guards around him put their hands on the handles of their swords.
I cursed in my heart, my mother would really find us a job! !
"I object! Don't you just want to kill us? Come and have fun if you dare!"
"Palm mouth!"
The guard stepped forward, opened the cell door and slapped the prisoner twice.
The prisoner suddenly huddled in the corner in aggrieved condition.
The other prisoners also looked at each other in shock.
After being a pervert all your life, do you think you have met a real pervert this time?
There must be something wrong with your medicine! And bonuses will be given out after autumn, you can’t even think of that!
If I am still serving a life sentence, I might as well die as soon as possible to enjoy my life!
Seeing no one objected, Fang Zhengyi was very satisfied.
"Okay! Then let's start the experiment. Go and bring them out one by one in pairs!"
The guard opened the cell door and led out the two death row prisoners. Then several people came forward and pressed one of them down on a chair. Fang Zheng picked up the needle and inserted it into the blood vessel of the death row prisoner and slowly injected it.
The first time he gave someone an injection, Fang Zheng broke into a cold sweat on his forehead. Fortunately, it ended quickly.
The second prisoner was pressed on the table, took off his pants and had an injection given to his butt. This was quite easy!
After the two death row inmates received their injections, a label was placed on their arms and they were put back.
Soon more than fifty people followed the same pattern one by one, and they were all finished.
...........
An hour later, Li Yuanzhao burst into the dungeon wearing a guard uniform and yelling!
"Lao Fang! Lao Fang! How are those death row prisoners! Success!"
Li Yuanzhao was very nervous. Whether his sister could survive or not depended on him!
Fang Zhengyi stood facing the curtain and turned around when he heard Li Yuanzhao's shout.
The candlelight in the dungeon flickered one after another, and the changing light and shadow continued to reflect on the square and angular face, looking mysterious and unpredictable.
Facing Li Yuanzhao's hopeful gaze, Fang Zheng turned around slowly, with a huge sense of loss and a hint of sadness in his voice.
"All dead."
