After Liu Yun drank a few sips of strong tea, his spirits improved, and finally under Kong Yuling's records, he reached a deal with Lu Liu and Smith and signed a formal agreement, fortunately, the pharmaceutical factory has already started operation, and it is not difficult to complete this order within ten days.

In the agreement, it is required to exchange 90 kilograms of penicillin crystallization and 200 kilograms of sulfonamide tablets for steelmaking equipment worth 3 million silver dollars, penicillin is indeed much more valuable, after all, sulfonamide tablets are simpler to make, and the raw materials have already been available, but the purification problem cannot be solved, so the price is only 0.5 US dollars / gram, fortunately, there are many raw materials, fast purification, and the price is not low.

After sending Smith and Lu Liu away, Liu Yun, Kong Yuling, and Pang Yuyan's father and daughter cheered and began to celebrate the official signing of the first order, and Kong Pang The two eldest ladies, after all, are young and have not seen much, and they are ecstatic for the big order of 3 million, especially these drugs, which are made by them themselves, and there is a great sense of achievement.

In the past ten years, he has helped the Xikang Liu family to preside over various businesses in Shanghai, and he has never seen a few orders of more than 1 million, and he wanted to help Boss Li and Mr. He raise a little food, medicine and guns, everyone went through several twists and turns, and it took several months.

What's more, every day at the risk of killing the head, frightened, no one is embarrassed, the total transaction volume is about 1 million, and the net profit can be 200,000, which is considered luck, by the way, such a profit, and Liu Yun's family in the name of a person, either owed, or exempted.

Look at the present, the money-making method of this pharmaceutical factory is even more powerful than robbery, not to mention Kong Yuling's penicillin, the unit price is hundreds or thousands of times that of opium, it is an inconspicuous sulfonamide tablet, and it is also a huge profit in a huge profit, and the cost of raw materials is only about 10,000 silver dollars.

After making medicine, the backhand is 300,000 silver dollars, Pang Taishi thought, if he had known that he could make so much money, his grandson would have wanted to do a head-killing business, smuggling guns and opium is really not done by people, which is like now, a single business is 3 million, if it is divided according to the shares of the United Pharmaceutical Factory, the shares of Pang Yuyan's father and daughter are as high as 15%, that is, 450,000 silver dollars.

Fortunately, Pang Taishi still didn't know the true value of the steelmaking equipment exchanged, if he knew that it was this medicine, and exchanged for goods worth 50 million, if he shared it according to this proportion, the two of them would become multimillionaires overnight, and it would not burst blood vessels.

After the small calculation, looking at the lazy Liu Yun, Pang Taishi suddenly remembered that this guy was not only the deputy director of the Sino-German Joint R&D Committee, but also the brother of Major General Qin of the Hanyang Arsenal, and also served as the commissioner of West Sichuan County and the section chief of the lieutenant colonel of the Ordnance Industry Administration.

When he saw Kong Yuling inadvertently, Pang Taishi felt a little bitter in his heart, no matter how good his daughter was, she couldn't win the daughter of the Kong family, and suddenly her heart moved, if you can't be your in-laws, can't you still be Bole, who said that the Liu family in western Sichuan in the future is not as good as the Liu family in Xikang.

What's more, these two Liu families are a family in their ancestors, Pang Xuezhong thought that if he changed his court and took refuge in the Liu family in western Sichuan, others should not say anything gossiping, anyway, the Xikang Liu family also lacks trust in themselves, if they are mixed with Liu Yun now, then they are the earliest entrepreneurial fathers of the Liu family in western Sichuan, and the more they think about it, the more they feel it, and they decide to do it from then on.

Liu Yun didn't think too much, he was too tired, and before Kong Caishen came back, he went to sleep by himself, and when he woke up, it was already the early morning of the next day.

After breakfast, Liu Yun and Kong Yuling together, sent Pang Xuezhong and Pang Yuyan away, a returnee was reminded by Master Pang, only to remember to report his father's safety, so he had to write a letter to his family in a hurry, Miss Kong is as careful as dust, and has already prepared a lot of gifts, please Pang father and daughter, to the future father-in-law Liu Ebei, and a letter of greeting from Kong Cainu.

It is also a letter, Liu Yun saw that his words were like a dog crawling, but the letter of Kong Cainu was a dragon flying and phoenix dancing, juan Xiu was powerful, and at a glance he knew that he was from a famous family, and he was ashamed, so he had to comfort himself because he was from the 21st century and was used to using a fountain pen.

After Mrs. Pang left, Liu Yun felt that his heart was empty, as if he had lost something, could it be that he fell in love with Pang Yuyan, wouldn't it, he has always regarded her as a sister, could it be because he remembered the reason for the sake of Zhongcheng Gong Qingzi, well, it is possible, but should he go to see her, in case he fights with Yuan Qi'er, a fart worm, and Funakoshi Yoshizhen as soon as they meet, what should I do, I have little arms and legs, can I persuade her.

Forget it, too lazy to think too much, it's better not to go, Liu Yun thought that anyway, it is necessary to further improve the performance of penicillin, remember that in the 21st century, there is still a difference between potassium and sodium, and what is the difference between oral and injection, well, by the way, we also need to study a pharmaceutical machine, which can make penicillin crystals and sulfonamide crystals into injectable penicillin injections, and add some starch to make oral sulfonamide tablets.

When Liu Cheng really began to improve penicillin and sulfonamide tablets, he found that things were far more complicated than expected, such as how to package the finished drug, which is a big problem, the two types of crystals are most afraid of moisture, and they must avoid contact with impurities in the air, so it is best to use vacuum aseptic operation, which may be a simple problem for the 21st century, and for 1934, it is a fatal thing, no less than the moon landing program.

Fortunately, someone carries six ant robots, need any machinery and equipment, as long as you can think of it, these robots will do it, according to the memory of the 21st century, the best way to preserve the drug, is to use a small glass bottle in a vacuum state, this is easy to do, just find some glass, let the ants purify and process it, forming a small glass bottle per 10 grams, but there is a small problem, in the future, it can not always be processed by robots.

The real reason for this is that if natural penicillin has not undergone special treatment, it cannot be 100% soluble in water, of course, after ant processing, you don't need to consider this link, and even the drug effect is better, and the side effects on the human body are much less.

However, when industrial production is needed in the future, it will have to be redesigned, but fortunately, Kong Caishen and Kong Yuling have already thought of the front, and have contacted a large number of medical experts through overseas relations, such as Chin Inn, Florey and Hitley of the Massachusetts Institute of Technology, as well as Dumac of Germany and Trefoer of France, etc., which will greatly liberate the work of ant robots.

When Liu Yun learned that these cattle were willing to come to China to cooperate, they were also red, and then thought about it, these people were the real creators of penicillin and sulfonamide tablets in the original timeline, and now they are just turning a corner and returning to the starting point, and they have made these drugs just to better resist Japan, these people are willing to join, in fact, it is also a good thing, if possible in the future, why not return the Nobel Prize to them, our character is not bad.

For several days, Liu Yun was busy improving all kinds of pharmaceutical technology and equipment, basically between Kong's villa and the China United Pharmaceutical Factory, forming a two-point and one-line life pattern, until one day, Major General Qin and Kong Caishen came to him together, saying that the general adviser of the German military advisory group, General Hans von Seckt, and some members of the advisory team, were about to arrive in Hankou, and Nanjing informed the Hanyang Arsenal that please do a good job in the assembly and testing of the prototype engine.

Not to mention that Dr. Liu almost forgot, no wonder the God of Wealth Kong, who has a lot of opportunities, will stay in Hankou for so long, it turns out that he has already prepared, and even Minister Kong is the real director of the "Sino-German Joint R&D Association", Liu Yun is secretly glad, fortunately, he has already predicted.

Not only did they ask the "one and two teams" of the arsenal to make good engine parts, but they also pre-researched the chassis and artillery fire of the future tank, and also ordered the ant robot to make some engine spindles and parts, but it would be good to assemble and test them before Admiral Seckert arrived.

This time Liu Yun is much more reliable, in order to cover the ant robot in the mine, in Kong's villa, secretly processed some spindles, just asked someone to transport them to the Hanyang Arsenal, Kong Caishen saw that these parts were actually moved out of his house, and he was immediately dumbfounded, and wiped his eyes several times, I really can't imagine how Dr. Liu did it.

Fortunately, the engine spindle, one is only a few dozen kilograms, a strong man can take it away, Kong Caishen and Qin Guodong's entourage is like a cloud, carrying this thing, it is still easy to be competent, a small cargo ship, directly from the harbor near the villa, transported to the cargo port of the arsenal.

When Kong Caishen and Liu Yun arrived at the arsenal, Qin Guodong had already ordered the guards to carry out a completely closed martial law, except for the experts of the Sino-German Cooperation Institute, the chassis team and the artillery team, and their necessary personnel, the rest were not allowed to approach, and the possibility of leaking secrets was eliminated as much as possible.

At the same time, for the sake of convenience, Director Qin also specially found a place near the director's office with good confidentiality conditions and convenient transportation of things.

Liu Yun has done many prototype engine assembly activities under the simulation of the brain, but he is not afraid to show everyone on the spot, before assembling, first test the results of other teams, Hu Youbing's 88mm tank gun has been completed, the use of smoothbore guns, and fixed tail shells, as for the automatic reloading device that someone inadvertently mentioned, it is still being studied, and Lee Hans of the artillery team promised that it will come out in a few days.

Zhang Sili's tank chassis also came out, using the torsion bar suspension system, he was able to develop it in time, in addition to the ant alloy provided by Liu Yun, there was also the help of Dalite and Ouyang brothers, they helped improve the tools for chassis processing, and also installed two engines by themselves, which were 100 horsepower German originals, and the test effect was also unsatisfactory.

Liu Yun looked at these parts and finished products, and had some feelings, this is the scientific and technological strength of China in 1934, if it is said that compared with innovation, conception, or hands-on ability, the Chinese people are actually no worse than any country in the world, what is really worse is the ability of large-scale production.

Liu Yun remembers that on the Internet in the 21st century, some military enthusiasts once counted the munitions production capacity of each major participating country in World War II, taking the aircraft production in 1944 as an example, the United States alone produced nearly 100,000 aircraft, many of which were four-engine bombers, twin-engine medium bombers, and twin-engine medium-sized transport aircraft.

However, even the Soviet Union, which was in ruins, also produced about 40,000 aircraft in this year, and at the same time, China, with the assistance of the United States, produced 600 aircraft in the entire World War II, and the core components were all imported, which was stronger than pure assembly.
