"Have you passed on all the methods of penicillin? Penicillin is actually a controlled substance and a prescription drug. I am not a medical student, so it is difficult to know the specific formula and data process. I am trying to check it carefully, and I can only place my hope in you. The Kyushu Academy of Sciences has great capabilities and can configure it as quickly as possible through trial and error."
Zhang Zhi stood in front of Li Zhen and spoke extremely quickly.
As he spoke, his eyes turned red: "You still have two months. Where will people go after they die? Is it true that after you die, I will never be able to communicate with you in dreams again? Li Zhen, Please be sure to cure this disease. I am so incompetent that I cannot obtain very specific penicillin purification data."
Li Zhen looked calm, and he had completely accepted this fact.
Just say: "It doesn't matter. Time is also destiny. Now that the seeds have been sown, then leave your life to God. After knowing that any effort is in vain, in fact, you should not waste your efforts and do more. Meaningful things are better. Also, internal combustion engine, I want to hear about internal combustion engine now. If the car engine you mentioned is an internal combustion engine, then what kind of structure is in the car engine? "
"Well, it's hard for me to imagine it based on your description. This time is too urgent. I don't know if I can see the moment when the internal combustion engine appears before I die. It's a pity that you can't draw the blueprint like me in this dream... "
Zhang Zhi's eyes turned red: "How about we get penicillin first? Forget about the internal combustion engine for now."
Li Zhen said seriously: "Zhang Zhi, if penicillin is not developed within two months and I die two months later, then will all my energy for the rest of my life researching penicillin become a useless effort?" What? If I die in two months and can leave something in this world, will what I do become meaningful?"
"Okay... internal combustion engine..."
Zhang Zhi sobbed.
——
When I woke up from the dream, it felt like a lifetime ago.
Ten thousand years ago, Zhang Zhi got up from bed and quickly called his father.
"dad."
"Huh? Are you crying? Why are you crying? What's wrong with you?"
"Dad, do you know anyone who runs a pharmaceutical factory? Or can you find someone who understands pharmacology?"
"What are you going to do?"
"I want to know the specific preparation method of penicillin. I want the specific process of purifying and making penicillin, including all the data."
"Why are you studying this? Why are you crying? Penicillin... you buy it. They are sold in hospitals. Oh, yes, prescription drugs are not sold casually now, but your uncle owns a pharmacy, so you can buy it if you want... "
Zhang Zhi was inexplicably upset and shouted: "I don't want to buy it. I want the formula! I want the formula! I want all the data on the separation and purification of penicillin, I want the data!"
“…”
Zhang Zhi's father was silent for a long time on the other end of the phone and sighed: "I don't know anyone who runs a pharmaceutical factory."
Zhang Zhi hung up the phone and rushed to his school. She looked for people everywhere, looking for professors of biochemistry in school, looking for teachers, looking for experts.
She asked one by one about the specific purification and separation methods of penicillin, as well as the various data of penicillin.
What can be found on the Internet is only the research history of penicillin and its general purification principles. The data contained therein are extremely confidential and cannot appear in public view at will.
But Zhang Zhi was disappointed, and no one knew.
Once a thing is researched, the manufacturers who produce it will naturally understand what is in it.
Just like everyone of us eats rice, professional old chefs can make rice in various ways. But it is impossible for the old chef to explain the principle of genetically modified rice, or the specific data of each type of rice.
The same is true for penicillin. Something that has become very common in the world, but when you really want to restore it, you will find that it is basically impossible...
Everyone knows that penicillin causes mold on melons and steamed buns if they are stored for a long time. After that layer of mold is purified and cultivated, it becomes penicillin. That layer of mold has extremely strong medicinal value.
The principle is simple. But...purification, separation, this is the real difficulty.
You must know that that layer of mold contains not only penicillin and streptococci, but also many other bacteria.
How to filter out only what we need from this layer of mold. This is the problem.
Zhang Zhiji almost collapsed and cried bitterly.
She was extremely uncomfortable. She had always responded to Li Zhen's requests and answered all his questions. This time, she really couldn't answer...
After finishing a class, Zhang Zhi did not leave the classroom, but lay on the table and sobbed.
A teacher from the philosophy department passed by and saw a female student crying and walked in: "Haha, classmate, why are you crying here?"
Zhang Zhi wiped away his tears and forced a smile: "I'm sorry, teacher. I'm leaving now."
The philosophy teacher looked at her with a smile: "I see a sense of powerlessness in your eyes. I teach philosophy and have also studied some psychology. Maybe I can enlighten you."
The suicide rate in universities is extremely high, coupled with the generally weak psychological quality of students today. Therefore, professors particularly like to enlighten others and relieve students' psychological burden.
Crying alone in the classroom made the teacher of the philosophy department feel that he must enlighten her.
Zhang Zhi smiled and was about to leave, but suddenly his heart moved and he asked: "Teacher, do people have souls?"
The teacher in the philosophy department was obviously surprised that she would ask this question. He hesitated for a long time and shook his head: "No."
"There was once a famous 21-gram experiment. Scientists put a dying person on a bed that could be weighed. The moment the heart stopped beating, the person's weight decreased by 21 grams. So it was concluded that the weight of the human soul is 21 grams. How could it not have a soul?”
The philosophy teacher smiled slightly: "Not from a medical perspective. From a philosophical perspective, do you know why there is such a thing as a soul?"
"have no idea."
"Human beings need a kind of spiritual sustenance, because everyone's psychological state of not wanting to die contradicts the cruel reality of the end of life. Therefore, from the psychological state, it gives rise to such a spiritual desire of human beings, which is also spiritual sustenance. Yes A yearning for the future. We educate ourselves that death is not terrible, because after death, the soul will go to a paradise world, and there will be no pain in heaven. Therefore, the theory of the soul appeared. From the time when humans began to have civilization, Human beings believe that the soul exists.”
Zhang Zhi added: "I think human beings have souls. Because many people have near-death experiences before they die... "
The philosophy teacher laughed: "Illusion."
"How can it be an illusion? They feel so real."
"Now let's elaborate on this philosophical issue from a medical perspective. The human brain is a very mysterious institution. It secretes various magical substances, one of which is called dopamine."
"I know about dopamine."
The philosophy teacher nodded: "Let's put this aside. Let me tell you, after death, there is actually nothing. Death means disappearance and annihilation. It means that from now on, this person will never leave in the world again. Leave no trace, and the world continues. Human beings always think of themselves as being great and having a special structure, but in fact they are not. Although we are advanced animals, we are still not out of the category of animals. High intelligence does not mean that we are out of touch with biology. academic category.
Death means leaving nothing behind. "
Zhang Zhi laughed and said, "Your answer is cruel."
The philosophy teacher smiled and said: "It's very realistic. Now back to the issue of dopamine. Let me tell you something more cruel, realistic and desperate."
Zhang Zhi was silent for a while and said, "Teacher, aren't you afraid that I won't be able to think about it?"
"No, because after you listen to what I'm about to say to you, you will understand the meaning of living."
Zhang Zhi's heart moved: "Please tell me, teacher."
