Although Qin Di tried to refine the elixir and provide it to his family to swallow, he could not guarantee that every loved one would live a long life.

Of course, longevity is relative, as a mortal, it is not difficult to live to the age of eighty, it is more difficult to be a hundred years old, and one hundred and twenty years old is extremely rare.

According to records, the longest-lived person in the world was a French woman who lived to be 122 years and 164 days. There was an old man in Japan who lived to be 116 years old. And the longest-lived person in China, it is said that Li Qingyun, who was born in the sixteenth year of Kangxi and died in 1933, lived to be 256 years old, married 24 wives, and gave birth to 180 children.

Qin Di's skill has reached the fifth level of qi refining, even if he doesn't make the slightest progress from now on, he can easily live past 160 years old. If his skill increases a little more, when he reaches the Great Perfection of Qi Refining, he will be able to have a lifespan of 250 years like Li Qingyun. If you are lucky enough to build a foundation, you will live to be at least 400 years old.

Sometimes, he wanted to see if that Li Qingyun was the Great Perfection of Qi Refining.

However, this person lives in seclusion in Sichuan, and he doesn't know which small mountain village he is hiding in, or in the Xianshan Cave Mansion, so it is not easy to find.

A few more days later, on August 6th, dog days, it was even hotter and there was no wind at all.

Qin Di walked out of the house to meet his grandfather Zhu Mingcheng.

Zhu Mingcheng is almost 70 years old, and his original wife, that is, Zhu Wan's mother Qian Rui, has died of illness for a long time. The wife he remarried was surnamed Liu, named "Liu Qing".

Zhu Mingcheng had a son and two daughters with Qian Rui, and a son and a daughter with Liu Qing. The age of the children varies widely, from the older being close to 50 years old and the younger being less than 20 years old.

Liu Qing welcomed Qin Di in, then served tea and greeted him eagerly.

"Adi, you have come too few times, you have to come more in the future!"

"Okay, I'll come often in the future!" Qin Di thanked him repeatedly, then sat down and talked to his grandfather.

Zhu Mingcheng said to him: "Last month, the president of Fudan submitted his resignation, and the new president has not yet been elected, I am the vice president, and in two years, I will retire." Adi, while I haven't withdrawn yet, I can help you get a degree. You're 22 years old, you haven't gone to school for a day, you don't have a serious education, and you'll suffer in the future. ”

Qin Di blinked his eyes and said with a smile: "Grandpa, is this thing easy to handle?"

Zhu Mingcheng said: "It's not difficult. You donate tens of thousands of dollars to the school. I'll talk to a couple of principals and ask them to give you a separate test. The topic is very simple, with your knowledge is to go through the motions. ”

"Oh well. Which subject do I choose?"

"Literature, science, law, business, you choose. ”

Qin Di thought for a while and said, "I'll choose science." I don't know if there are any textbooks, I just need to read them for two days. ”

Science includes mathematics, physics, and chemistry, which are counted as science subjects together, and each subject has a specific subject of study.

Zhu Mingcheng helped him find some books and asked him to go home and read them.

Later, after a month of operation, Qin Di got a diploma from Fudan University, nominally a graduate of a famous university, but he didn't even have a classmate, and he said outside that he graduated from Fudan in the future, but I am afraid that he could not find a witness. But in the school archives, there is a record of his graduation in 1922.

In mid-September, he received a letter from Wallace saying that the patent application for penicillin had been accepted by the United States Patent Office and had been approved, and that the European patent application had been acknowledged.

At this time, the Institute of Medicine made a new breakthrough and obtained a strain with a yield of up to 1,000 units.

To this end, Qin Di strengthened the management of each generation of strains, numbering them separately and sealing them in secret places.

At the same time, he bought a large plot of land near Xujiahui in the French Concession and began to build a factory to prepare for the large-scale extraction of penicillin. Outside the factory, a high courtyard wall was built. The large heavy iron gate looks like a prison. Fortunately, there are a few big words written on the side of the door, "Guotai Pharmaceutical", which makes people breathe a sigh of relief.

On January 2, 1923, Mr. Sun issued a new program for the Qingbai Party, which was divided into two parts: the Three People's Principles and the Five Rights Constitution. The Three People's Principles refer to the nation, civil rights and people's livelihood. The five-power constitution refers to the legislative power, judicial power, executive power, procuratorial power, and examination power. In fact, it is a hodgepodge of Chinese and Western styles.

On January 12, the two parties began their first cooperation. On February 4, there was a general strike on the Jinghan Railway. On March 1, Mr. Sun reorganized the Generalissimo's Office.

By mid-March 1923, several batches of penicillin had been produced.

Qin Di was not in a hurry to sell, but sent the relevant papers.

The paper was divided into two parts, the first part was published in the June 1923 issue of the New England Journal of Medicine, which devoted 38 pages to the discovery of penicillin, the extraction of penicillin, and the preparation of penicillin sodium salt, and the second part, published in the British Lancet, reported 300 clinical cases of penicillin use. The paper was signed by two people, Qin Ling was the first author, Zhu Wan was the corresponding author, and Qin Di's name was not on it.

As soon as the paper came out, it immediately caused a great sensation.

Almost the whole world, all doctors and pharmaceutical companies know about it: Nobel Prize winner, great physician Zhu Wan, and her young daughter have developed an epoch-making new drug that can effectively fight bacterial infections.

Immediately, many laboratories were scrambling to carry out research, and many people traveled all over the world to search for moldy plaque and try to screen for penicillium.

In just two months, a preliminary repeat experiment was carried out, demonstrating that the substances released by Penicillium on the culture plate inhibit the growth of surrounding bacteria. However, these people later found that it was very difficult to extract penicillin! If they wanted to enter the clinic, they needed to cross several chasms, and the difficulties they faced were very great!

It was only at this time that Qin Di began to sell penicillin, half of which was sold abroad and half at home.

Because it is a new drug, it is the only one, there is no other branch, and the price of penicillin is very expensive, but the sales are very good.

In these years, there are many terrible diseases, pneumonia, plague, diphtheria, tuberculosis, cholera, ravaging Europe, America and Asia, human beings lack good antibacterial drugs, whether it is penicillin, or sulfonamides, are life-saving medicines. And the patents of these two drugs are in the hands of Zhu Wan!

In October 1923, less than four months after the publication of the relevant papers, the Royal Swedish Academy of Sciences hastily announced that Chinese scholars Zhu Wan and Qin Ling, mother and daughter, shared the Nobel Prize in Medicine this year!

When the news reached China, it once again caused a great sensation!

"Wow, that's amazing! Chinese scientist Zhu Wan has once again made an amazing feat!"

"This time, not only Zhu Wan herself, but also her daughter Qin Ling shared the Nobel Prize, which has become a good story praised by the world!"

"This is an inspiring event! It has carried forward the national spirit, and we should vigorously commend them!"

"Who said that women are inferior to men! All men in the world should feel ashamed!"

"Mr. Zhu Wan has won the Nobel Prize twice!

"I heard that Qin Ling hasn't been out of the cabinet yet, and at such a young age, she has such an amazing contribution, I don't know which man can be worthy of her!"

Soon after, on behalf of the government, President Cao Kun sent a telegram commending Zhu Wan and Qin Ling with a reward of 500,000 yuan each! Mr. Sun of the Qingbai Party personally wrote an article in the newspaper, praising the mother and daughter as "the elite of the nation and the model of women"!

Subsequently, Zhu Wan donated 500,000 yuan to the disaster area, winning more people's praise.
