For any era, it has its own unique characteristics.

At the end of the 19th century, China entered one of the darkest periods in its 5,000-year history, but for Europe and the United States, it was a golden age that had never been seen before. The second industrial revolution has begun, major powers are seizing the chassis all over the world, and science and technology are advancing by leaps and bounds at an unprecedented speed!

As one of the oldest disciplines, medicine is naturally no exception.

In the 100 years from around 1850, it was the period when modern medicine began to germinate and establish its positioning, and in the East, traditional Chinese medicine began to be violently impacted, and the future was gradually forced to survive in a corner, and the same is true in the West, the ancient medical schools began to gradually withdraw from the stage of history.

There is no doubt that the decades of the late 19th and early 20th centuries were the most critical periods for the development of medicine.

During this period, medical masters frequently appeared, such as Pasteur, Koch, Liszt and others, and a series of revolutionary achievements began to appear, such as aspirin, such as X-ray; In the future, various sub-specialties of medicine have also begun to develop rapidly or sprout, such as the great progress in anatomy and physiology, the revolutionary breakthrough in foreign science and technology, and of course, the synthesis of chemical drugs......

Ehrlich, without a doubt, was a pioneer in chemical medicine.

This Nobel Prize-winning bull invented the famous 606 (Sherversan) in history to treat syphilis, although it was later banned because of too many side effects, but he undoubtedly opened the era of chemotherapy! It's just that in the world where John appeared, he took out sulfonamides decades in advance and snatched this honor away from Ehrlich.

But in return, John prepared a discipline system for Ehrlich!

The importance of immunology in the future medical system is self-evident, and at a time when immunology is just in its infancy and more of an empirical medical manifestation, John, who has a complete advanced theory of immunity. Undoubtedly the best guide in the world, the development of the Heinz General Hospital Institute under the leadership of Ehrlich, that is, the future Institute of Immunology, is destined to be extremely brilliant......

Of course, the current Ehrlich does not know this.

After getting John's test plan, Ehrlich quickly flipped through it, then stood up and said eagerly, "John." If nothing else, I'll go back and get ready...... Well, let's start the trial next week! ”

"Haha, don't worry!"

Waving his hand, John smiled and said, "Mr. Ehrlich, this experiment is actually not complicated, and it is not troublesome to prepare, so there is no need to be in a hurry. ”

"Hmm."

Looking at John's tone, Ehrlich knew that the other party still had something to say. I could only press the excitement in my heart and sit down again.

After Ehrlich sat down, he groaned slightly, and John said with a smile: "Mr. Ehrlich, since we have decided to do this experiment, then I have two requirements: first, I am very confident that the experiment will be successful, but you also know that I didn't have much time at the beginning. So I only did it twice, so this time it's up to you to preside over it. I hope to accumulate enough experimental data; Second, the preparation of serum is not troublesome, but the trouble is that the efficacy of the serum I prepared at the beginning is too low, if you want to use it on people in the future, you must purify it, and this work also needs you to do! ”

"No problem!"

After listening to John's request, Ehrlich nodded without hesitation and agreed.

In Erlich's opinion. John's demands were all very reasonable, and he had no reason to refuse. In fact, even if the other party didn't mention it, he had already thought of this just now.

"Good!"

Seeing Ehrlich nodding, John was naturally very satisfied.

John himself had no problem doing this experiment, but he was a little numb about how to purify the serum. After all, he has a head of knowledge. But the issues involving this kind of laboratory are still not very specialized. It's not that it's impossible, but it will inevitably consume a lot of time, so it's not very cost-effective. And in this regard, the best candidate is undoubtedly Ehrlich. In fact, although the diphtheria antitoxin serum was discovered by Behrin and Kitasato Shibazaburo, they encountered the same situation, that is, the efficacy of the serum was too low, and it must be purified before it can be used in clinical practice. And it was Ehrlich who helped them a lot, purifying the serum developed by Behring. However, Ehrlich later canceled his contract with the serum manufacturer, and Behring obtained an exclusive patent, and finally gained both fame and fortune......

After thinking about it for a while, John also smiled dryly: "That's it, Mr. Ehrlich, I will provide five thousand dollars for your experiments, of course, including the subsequent purification technology research, and the future papers will also be published by you and the research institute you lead, as for patents......"

When he said this, John hesitated for a moment before he smiled and said, "I personally paid five thousand dollars to buy all the patents and then handed them over to Heinz Pharmaceutical Company to produce, what do you think?" ”

"This ...... Are you serious? ”

After hearing these two figures, Ehrlich stood up again with a shocked face.

Two five thousand, that's ten thousand dollars!

As John invited from the University of Berlin to New York to take up a key position, his salary is naturally not low, but it is only more than a thousand dollars a year. Of course, in this day and age, it is definitely a high salary, you must know that the rank of Professor Burgman is now two or three thousand marks, which is much worse than him. So five thousand dollars must be a big number for him, not to mention that the experimental plan or something is from John, he is only responsible for the specific work, plus Ehrlich himself is an employee of the institute, the results naturally belong to John, five thousand dollars is a pure windfall, how can he not be surprised?

"Seriously, of course."

Smiling slightly, John's expression became solemn.

Five thousand dollars seemed like a lot, but it was absolutely nothing to him. And the point is that if Ehrlich really purifies the antitoxin serum for clinical use in the end, this is another gold mine that can bring a steady stream of benefits to himself! Now is the era of diphtheria, and there are millions of patients in Europe and the United States alone, and the price of buying a patent for $5,000 is quite low.

If it weren't for the fact that the plan was made by himself, John would have preferred to use the patent sharing scheme.

Encouraging subordinates to work hard and create more patents is undoubtedly the best solution, but unfortunately now is not the time. However, diphtheria antitoxin is followed by tetanus antitoxin, which is a life-saving weapon in the war, and John plans to just remind him to let Ehrlich do it himself, and then the huge share of income will undoubtedly inspire more researchers to work hard to develop it......

With a heart full of joy and a little doubt, Ehrlich went back.

As for John's words, he left after a while in the office. However, instead of going straight home, he had the driver drive him to the Heinz pharmaceutical company, where the elder Huntelaar and the company's management were waiting for him.

Seeing John's arrival, old Huntelaar asked expectantly, "John, what are you asking me to do here today?" Could it be that there are any new products that have been developed? ”

"Hmm...... Sort of. ”

Shrugging his shoulders, John said with a smile.

"Sort of?"

Hearing this answer, the old Huntelaar and the management of Heinz Pharmaceutical Company immediately looked at each other, and they were a little puzzled.

But before they could ask, John went on to explain: "Gentlemen, I have asked you to come here today because I want to announce one thing, and that is that by the end of this year, I want the company to have at least fifty thousand dollars in cash!" ”

"Fifty thousand dollars in cash? What are you doing? ”

Hearing the number of 50,000, old Huntelaar couldn't help but be shocked!

With the foundation of the Berlin Heinz pharmaceutical company, although the New York factory is relatively inefficient and the growth rate is relatively slow, after all, the drugs produced are very popular, so there is no doubt that this year will be profitable. It's just that compared to the European market, the United States is still a little smaller, so everyone expects a net profit of $100,000 by the end of the year!

It is indeed not difficult to come up with 50,000 US dollars.

But......

Under the expectant gaze of everyone, John smiled slightly: "Sir, I need to buy a farm around New York, the area should not be too small...... $50,000 should be enough, right? ”

"Fifty thousand dollars is definitely enough...... But what do you buy a farm for? ”

After listening to John's words, old Huntelaar's expression became more and more surprised.

There are few people in the United States, and the price of land has never been expensive except in big cities, and even after more than 100 years, the price of farms is generally not high, and hundreds of thousands of dollars can buy a very large one, let alone in this era. But like the management of other companies, old Huntelaar really couldn't think of what his grandson would do when he bought a farm, could it be that this kid suddenly wanted to farm?

"Hehe, raise cattle!"

Grinning and revealing a mouthful of snow-white teeth, John's expression at this time was filled with an indescribable strange smell...... (To be continued......)
