In Berlin in September, the weather is starting to get cooler.

John's life was prosperous, and he was busy running around every day, wishing that Benz and the others would immediately build a perfect car and save them the pain of riding in a carriage every day.

The medical device manufacturing plant is almost set up and is expected to be officially put into production soon, and the entire set of surgical instruments, blood pressure monitors, stethoscopes, thermometers and other products improved by John are also on the production schedule. As for the dye factory, John has also found a number of people to help him, including Baron Cole, Mr. Brist, and a professor of chemistry at the University of Berlin, who has reluctantly dealt with the professor of chemistry, and John asks them to help him find a qualified manager and a technical leader.

Of course, the conditions are very open, and it is definitely the highest level in Germany at the moment.

The rest of his energy was focused on helping Bergman renovate the surgical building in batches. This was Bergman's request on his own initiative, because no matter how detailed John's proposal was, Bergman still couldn't grasp the details, so he had to help design and supervise the construction.

It was also a new challenge for John.

However, considering that after returning to New York in the future, he would have to renovate his hospital and other matters, of course, John agreed without hesitation, and spent every day recalling the various facilities he had seen in the hospital in his previous life, and renovating the surgical building, while also wondering whether he should make a surgical management system or something like that......

Before you know it, a new semester at the University of Berlin is about to begin.

The school ended up giving John two courses: physiology and surgery. Then John discovered something very interesting: as a teacher, when he was taking a surgery course, many of the people sitting below him might have been friends he had made since he came to Berlin!

This interesting situation made John secretly happy in his heart.

"What a chance, what a chance!"

Thinking of this, John sued himself countless times.

The building in New York could be completed by the end of next year. When John returned, it would be renovated until it opened, which meant that John needed a lot of physicians to fill the building. The current situation of medical schools in the United States determines one thing, that is, there will be no good schools before the establishment of Johns Hopkins School of Medicine, which means that there was no modern medical school in the United States in the true sense before 1893, and naturally there will be no good source of doctors.

Historically, the best physicians in the United States have either immigrated or returned from studying in Europe. So if you want to recruit staff for your New York hospital in this era. Germany is undoubtedly a great place to be. As for the University of Berlin, half of the international students in the United States will study at the University of Berlin, what could be better than that?

Therefore, John attaches great importance to the two courses he teaches.

Needless to say, John has already planned to take advantage of his time as an associate professor to come up with more basic theoretical things in the next year or two, such as the theory of body fluids, blood transfusion, metabolism and nutrition, and even shock, and even more about physiology...... It just so happens that he has always collaborated with the physiology room. Definitely a great opportunity.

A year or two is enough time for him to come up with a lot of things......

……

On this day, not long after John returned from the construction site on the second floor, a nurse knocked on his door: "Mr. Huntelaar, your letter. ”

"Put it on the table, thank you."

John, who was preparing for the first class tomorrow, didn't look up and said casually.

After putting down a few letters, the nurse went out, but John was busy for more than half an hour before shaking his head. Raised his head from the lesson plan. Teaching college students in this era is really not an easy thing for him. You must be prepared for what should be said and what should not be said, otherwise it will be quite troublesome to accidentally throw out the theory that will be decades later.

"Two German, one Austrian, and three English ......"

As a break from work, John began to look through today's letters. Since his papers have been published one after another. Letters gradually increased, and people in this era were accustomed to the exchange of letters, especially among scientists, and John had long been accustomed to it.

But......

"Huh?"

When he saw a letter from England, John was stunned.

What a thick letter!

Generally speaking. John's letters were written to his colleagues, either surgeons or physiologists, and most of the content was about disinfection, local anesthesia, or blood type, whether they were consulted or questioned, and all of them were only five or six pages at most. But the letter in front of him was several times thicker than an ordinary letter, at least twenty pages long, which made John a little strange.

"Did you send a paper paper? No, at least two! ”

While secretly speculating, John opened the letter, which was somewhat unusually thick.

"Dear Mr. Huntelaar......"

The beginning of the letter was very ordinary, and there was nothing special about it, and John looked at it with some absent-mindedness.

Like other English gentlemen, the letter began with a lot of nonsense, nothing more than admiration for John's achievements in medical research, and his own admiration for it, and so on. After almost half a page, he finally got to the point, and the other party asked John very sincerely about some problems in ABO blood group theory, mainly focusing on how to identify different blood types and whether dried blood can be used......

Looking at it, John couldn't help but frown.

It's not that he's impatient, in fact John will be very patient with anyone who cares about ABO blood type, because there are so few people who care about blood type compared to aseptic disinfection and local anesthesia techniques that only a small percentage of physiologists are interested. But these questions asked by this gentleman ......

It's so easy!

In fact, the blood group theory itself is not complicated, it is easy to understand and not difficult to verify, and physiologists can easily verify it in the real room. Therefore, in the few letters I have written before, most of them have discussed with John the meaning and future application of blood group storage. But this letter to John felt completely different, as if the other party's understanding was very superficial, purely to ask himself for some popular science knowledge of blood group theory......

After turning the first three pages, John was still confused.

He didn't understand whether this was a physiologist or surgeon who was interested in blood group theory, and he couldn't even see the point of the other party trying to verify these basic science questions!

It wasn't until he turned to the fourth page that John was stunned after reading a few lines.

“…… Mr. Huntelaar, I'm an English physician, but I'm also very interested in literature, so after reading your paper, I suddenly had a very interesting idea: wouldn't it be a brilliant idea to incorporate the discovery that different people have different blood types and that blood can agglutinate with each other into a detective novel? After coming up with this idea, I couldn't control my impulse, and spent a month writing this "AStudyinScarlet", hoping that you could help me review the contents......"

《AStudyinScarlet》？

After being stunned for two or three seconds, John tilted his head in confusion: Why does this English title sound so familiar, as if he had seen it at some time?

Subconsciously, John began to search in his mind. This is his golden finger after crossing over, anything he has seen in his previous life can be retrieved in his mind, otherwise some basic knowledge that is basically not used after work may have been returned to university teachers through time and space.

That is, between breaths, John suddenly seemed to be struck by a bolt of lightning, and the whole person instantly stiffened for a moment, and then turned the letter to the last page with a pair of eyes to see the last letter writer!

Arthur? Conan? Doyle!

"I'll go!"

The moment he saw the name, John opened his mouth wide and exclaimed, "Conan Doyle? This is "A Study of Scarlet Letters"? Didn't this guy wait until 1887 to write the first part of Sherlock Holmes......" (to be continued......
