Two days later, Zhang Naijing took the first-class cabin of the "Leviathan" cruise ship and crossed the ocean to the United States.

Qin Di put aside the affairs at home and took Yan Xue to Putuo Mountain for cultivation.

Yan Xue's academic performance is very good, and she doesn't need to go to class every day.

Xiuzhen people have a strong divine sense, and their learning efficiency is many times that of ordinary people, and they can turn a book twice and do it, so they don't need to study step by step. Moreover, once you start to practice, you can also greatly reduce the amount of time you sleep. Like Qin Di, one hour of meditation a day is enough, and Yan Xue has to sleep for three hours.

In the north of the Fayu Temple of Putuo Mountain, there is a two-entry house, the door plaque reads "Yangxin Zhai", and it is surrounded by 100 acres of paddy fields.

After Qin Di took over the mansion from the Zhang family, he dismissed the servants in the house, leaving only one old servant to guard the door.

He found that the aura of Putuo Mountain was twice as strong as that of Jiaxing Nanhu, perhaps because it was in the middle of the sea, or because it was stained with the light of Guanyin Bodhisattva.

He taught Yan Xue the "Aoki Formula" and the "Weak Water Technique". Aoki can absorb the aura of trees and flowers, and weak water can absorb aura from rivers, rivers, and the sea.

Yan Xue possessed the Wood Spirit Root and the Water Spirit Root, and made rapid progress under his careful guidance.

Three months later, Qin Di advanced to the fifth layer of qi refining! Yan Xue finally completed her breakthrough and stepped into the first layer of qi refining! She began to follow Qin Di at the age of six or seven, and after five years of cultivation, she finally cut down her hair and washed her marrow and was reborn!

At this time, Yan Xue was twelve years old, her figure was one meter six, her skin was white and red, as if she was out of the water hibiscus, her eyes were as clear as Qiuhong, and there was no flaw on her body, she looked like a fairy in the sky.

Qin Di was very satisfied, and felt that this apprentice had good qualifications and was worth cultivating.

Although he took Yan Xue as a disciple, he directly called him by his name on weekdays.

Yan Xue calls him "sir" and does not call him "master". Because this is the secular world, if you call it "master", it will make people feel strange.

Subsequently, the two left Putuo Mountain and returned to the demon capital Qin Mansion.

Qin Ling and Qin Yue were very surprised when they saw Yan Xue again.

"Huh, is this Yan Xue? Why is her skin getting more and more watery, what's going on? It's so enviable!"

"You're so beautiful, you'll be captivated when you go outside!"

"Standing with you, am I in the mirror a yellow-faced woman?"

"Xiaoxue has grown up, this dress is not suitable, I will go to the street with my sister tomorrow and buy you a few good clothes!"

Yan Xue smiled shyly, like an orchid in the hollow valley.

When Qin Hancheng came home, after seeing Yan Xue, he almost lost his eyeballs!

"Oh my God! It's really a female college eighteen!

Yan Xue smiled sweetly: "Uncle, no matter how it changes, I am the Qin family." ”

Qin Hancheng's heart moved, and he said secretly: "My son is so discerning! I actually picked her out of the crowd five years ago! Now she is so beautiful, she can be used as a child daughter-in-law! Haha......"

In the past, he always felt that Yan Xue was an outsider, and he didn't understand why his son brought such a young girl back from outside, but now he has figured it out!

Men are visual animals, and women pay attention to their appearance first, and knowledge and wealth are secondary.

Because of this, Qin Hancheng thought crookedly and felt that his son was very powerful.

After another half an hour, it was getting late, and Zhu Wan entered the house.

She didn't pay attention to Yan Xue's changes, but excitedly told Qin Di: "There has been a breakthrough in Penicillium research! Two months ago, a 50-unit strain of Penicillium was screened out, and a small amount of penicillin was obtained. I tried penicillin in the clinic and treated two patients, and found that it was very effective, much stronger than sulfonamides!

Qin Di was also rejoicing: "Is it? This is good news!"

He discussed it with his mother for a while and decided to apply for a patent immediately, not for a few years like sulfonamides.

Historically, Fleming did not patent penicillin when he discovered it in 1928, and in 1939, the Oxford group in England conducted experiments to prove the effect of penicillin, and these people also did not apply for a patent. One of the important reasons is that they all have a strong dedication to believe that this life-saving medicine should belong to all mankind.

Later, however, in 1945, the Americans obtained the patent for penicillin, and from then on, the whole world had to pay patent fees to the United States if it wanted to produce penicillin. It can be seen that the realm of people is too different!

At this time, the Chinese people's livelihood was withering, all walks of life were very backward, and they were bullied by foreign countries everywhere.

Qin Di felt that since he had invested heavily in this research, he could not give the patent to outsiders, and in order to do something beneficial to the people, he had to grasp the patent in his hand!

The next morning, he went to see Wallace, the dean of St. John's University School of Law.

Just in time for Wallace to leave the magic capital and return to the United States, Qin Di talked to him and signed a series of agreements to entrust him with the patent application.

Wallace happily accepted, promising to do the same as he did last time.

Qin Di is not afraid of the other party stealing the patent, because the relevant papers have not yet been published, and the patent application only prepares penicillin, and does not write the role of penicillin and how to upgrade penicillium.

Strains of Penicillium with high yields are not readily available. It always takes years to find the right strain.

Qin Di held Wallace's signed commitment in his hand, as well as the detailed experimental records of many scientific researchers, even if it was preemptively registered, it could be resolved in a lawsuit.

In fact, a foreigner like Wallace, who has been teaching in China for more than ten years, is still a reputable foreigner, and as a lawyer, he must have professional ethics.

Wallace took a sum of money, took his wife and children, and left happily in the first class of the steamer.

Subsequently, the upgrading of Penicillium continued, and the researchers continued to irradiate ultraviolet light in the hope of obtaining higher yielding strains.

The bacteria are cultured in a shaker, divide quickly, and can be screened once a day, and after repeated screening, the strains are constantly upgraded.

Qin Di's goal is more than 5,000 units, because the higher the strain grade, the less raw materials are required to prepare penicillin.

In order to grow Penicillium, you must first have a culture medium.

The culture broth is prepared from grain, and chemical elements are added.

China has been experiencing famine for the past few years. From 1920 to 1921, there was a great famine in the four provinces of North China. In 1925, there was a great famine in Sichuan, Guizhou, Hubei, Hunan, and Jiangxi. In 1930-1932, there was a great famine in eight northern provinces. Either way, it's always good to save a little food.
