Rising: Ten Thousand Years Chapter 241: : The meaning of living

"Have you passed on the method of penicillin? Penicillin is actually a controlled drug and is a prescription drug. I am not a medical student, so it is difficult to know the specific formula and data flow. I hope that you Kyushu Academy of Sciences will be able to configure it as soon as possible through trial and error."

Standing in front of Li Zhen, Zhang Zhi spoke in an extremely fast tone.

As he spoke, his eyes turned red: "You still have two months left. Where do people go after death? Is it because after you die, I will no longer be able to communicate with you in dreams? Li Zhen, please also cure this disease. I am so incompetent, I can’t get very specific penicillin purification data.”

Li Zhen's face is calm, he has completely accepted this fact.

Just said: "It doesn't matter. Time is fate. Since the seeds are scattered, then give your life to God. When you know that any effort is in vain, in fact, you should not waste effort. It’s better to do more meaningful things. 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 a car engine?”

"Well, it's hard for me to imagine just relying 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 like me in this dream. Drawings..."

Zhang Zhihong stared: "How about getting penicillin first? Forget about the internal combustion engine first."

Li Zhen said seriously: "Zhang Zhi, if penicillin has not been developed within two months, I will die after two months. Then if I devote all my energy for the rest of my life to researching penicillin, it will become What about a kind of useless work? If I die two months later and I can leave something in this world, will my actions become meaningful?"

"Well... internal combustion engine..."

Zhang Zhi sobbed.

When I woke up from the dream, it seemed like a lifetime away.

Ten thousand years ago, Zhang Zhi got up from the bed and hurriedly called his father.

"Dad."

"Huh? Are you crying? Why are you crying? What's wrong with you?"

"Dad, do you know someone who runs a drug factory? Or can you find someone who understands pharmacology?"

"What are you doing?"

"I want to know the specific preparation method of penicillin. I want the specific process of penicillin purification and production, including all the data in it."

"Why are you researching this? Why are you crying? Penicillin...you buy it. Hospitals sell it. 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. 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 on the phone for a long time, and sighed: "I don't know anyone who runs a pharmaceutical factory."

Hung up the phone, Zhang Zhi hung up the phone and ran to his school. She looked for people everywhere, looking for professors of biochemistry in the school, looking for teachers, looking for experts.

One by one, she asked about the specific purification and separation methods of penicillin, as well as various data of penicillin.

What can be found on the Internet is only the research history of penicillin and the general purification principle. The data in it is extremely confidential, and it is impossible to appear in the public eye at will.

But Zhang Zhi was disappointed, no one knew.

If something is researched, then naturally only the manufacturers who produce it will understand what it is.

Just like each of us eats rice, professional old chefs will cook rice in various ways. But it is impossible for the old chef to tell the principle of genetically modified rice, and he cannot tell the specific data of each type of rice.

The same is true for penicillin. A thing 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 means that melons and steamed buns have been left for a long time, and the tops have become moldy. After that layer of mold is purified and cultivated, it is penicillin. That layer of mold has extremely strong medicinal value.

The principle is simple. But... purification, separation, that's the real difficulty.

Know that the layer of mold contains not only penicillin streptococcus, but also more other bacteria.

How to filter out only what we need from this layer of mold. This is the problem.

Zhang Zhi almost collapsed and cried bitterly.

She was extremely uncomfortable, and she had always been responsive to Li Zhen's requests and answered every question in front of Li Zhen. This time, she really couldn't answer...

After finishing a class, Zhang Zhi did not leave the classroom, but lay down on the table and began to sob.

A teacher from the philosophy department passed by here, saw a female student crying, and walked in: "Hehe, classmate, why are you crying here?"

Zhang Zhi wiped away his tears and forced a laugh: "I'm sorry, teacher. I'm leaving now."

The philosophy teacher glanced at her with a smile: "I can see the sense of powerlessness in your eyes. I teach philosophy and have some psychology as well. Maybe I can enlighten you."

University suicide rate is extremely high, coupled with the generally weak psychological quality of students today. Therefore, professors especially like to enlighten others and clear the psychological burden of students.

Crying alone in the classroom made the teacher of the philosophy department feel that he had to enlighten her.

Zhang Zhi smiled and wanted to leave, but suddenly his heart moved and he asked: "Teacher, do people have souls?"

The teacher of the Philosophy Department was obviously surprised that she would ask this question, hesitated for a long time, shook his head and said: "No."

"There was once a famous 21-gram experiment. Scientists put a dying person on a bed that could be weighed. When the heartbeat stopped, the weight of the person decreased by 21 grams. So it was concluded that the person's The soul weighs 21 grams. How can there be no soul?"

The philosophy teacher smiled slightly: "Not from a medical point of view. From a philosophical point of view, do you know why there is such a saying as a soul?"

"Don't know."

"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~IndoMTL.com~ So from the psychological state, such a human mind is born Longing is also the sustenance of the soul. It is a yearning for the future. We enlighten ourselves that death is not terrible, because after death, the soul will go to a paradise, and there will be no pain in heaven. Therefore, the soul theory appeared, from When human beings began to have civilization, human beings believed that the soul existed."

Zhang Zhi also said: "I think human beings have souls. Because many people have experienced near-death experiences before dying..."

The philosophy teacher laughed: "Illusion."

"How can it be an illusion? They feel so real."

"Now, let's explain this philosophical issue from a medical point of view. The human brain is a very mysterious mechanism that secretes various magical substances, one of which is called dopamine."

"I know about dopamine."

The philosophy teacher nodded: "Leave this point aside. Let me tell you, there is nothing after a person dies. Death means disappearance, annihilation. It means that from now on, this person will never be around again." There are no traces left in the world, but the world continues. Human beings always think of themselves as great and have a special structure, but in fact there is no such thing. Although we are advanced animals, we are still not out of the category of animals. High intelligence does not Represents breaking away from the scope of biology.

Death is nothing left. "

Zhang Zhi laughed and said, "Your answer is cruel."

The philosophy teacher smiled and said, "It's very realistic. Now let's go back to the dopamine issue. 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 think about it?"

"No, because after you listen to what I'm about to tell you, you will understand the meaning of life."

Zhang Zhi's heart moved: "Please tell the teacher."
