After coming out of Bergman's office, John was quite excited.

Sure enough, the surgeons who pioneered the use of steam sterilization were not the kind of people who were not the kind of people who were not conformists, and after examining John's basic knowledge on the spot, Bergman readily agreed to his request: he would be subjected to a series of rigorous examinations over the next two weeks, and as long as he passed, he could follow Bergman himself to train in surgery. However, under John's own strong request and careful explanation, Bergman also agreed that if he succeeded, he would only be arranged to train two days a week, and the rest of the time would be arranged by himself.

It has to be said that this big man in the surgical world is indeed very open-minded and very supportive of John's idea of conducting blood research at the same time. After all, advances in surgery and basic medicine are inseparable. It's just that Bergman can't help in this regard, and John can only seek the support of the physiology professor!

"Or do it yourself?"

The thought of having to convince another big guy made John have a headache. In fact, with the current conditions and his financial resources, it is not impossible to build a physiological room, but spending such a large sum of money will definitely provoke old Huntelaar, and John does not really want to do this for the time being. In addition, he must use animals to do physiology, and although this era is far less elaborate than later generations, due to a debate among the British ten years ago, the protection of animals is already in place, and it is quite troublesome to use them to make practical things.

After thinking about it for a while, John simply decided to do some basic preparation first, and wait for Bergman's exam......

……

Time flies, and the weekend is coming.

In the afternoon, one of John's best friends, Peake, walked up to him briskly and asked with a smile, "John, do you have any other plans for the weekend?" ”

John was slightly stunned when he heard this, nodded and said, "I need to go buy something tomorrow morning...... What, something is looking for me? ”

"There's a dance party tomorrow night, are you interested?"

Pique's voice suddenly lowered, and he asked with a smile.

"Prom?"

When he heard the word, John's heart shook.

It's been a long time since the last time Koch was at the ball, but Pique's "fun" ball hasn't been fulfilled until now. After all, with his family's wealth and status, it is indeed not easy to participate in a high-level ball.

Sure enough, Peake got closer and lowered his voice: "John, I promised you to take you to a fun ball, tomorrow is a good opportunity!" Tomorrow's ball will be very large, not only will there be many big businessmen and entrepreneurs, but also many nobles, and I have taken a lot of effort to get two invitations......"

Hearing Peake say this, John immediately understood why he was so quiet.

For young people, a lavish ball is undoubtedly very attractive, and of course it is quite difficult to participate, otherwise Pique would not have taken so long to come to John. It is conceivable that if Luther or someone accidentally hears the news, they may have to blame Pique for not being interesting enough.

So without thinking much about it at all, John immediately nodded and said, "Then of course I'm interested, tomorrow night, right?" In what place? ”

Just as he felt that life was monotonous and boring, and thinking of what Joshua was urging, John was also a little sick and rushed to the hospital.

"Hey......

Seeing John's reaction, Peake suddenly laughed sheepishly.

This guy's laughter made John confused, and he glared and scolded with a smile: "You guy, what are you laughing at?!" ”

He didn't care about his friend's laughter and scolding, his eyes narrowed into a slit, and he said happily: "John, I heard that there will be a lot of noble ladies attending this ball, and you must dress up handsomely, maybe you can take one back to the United States when the time comes......"

"Uh......"

Seeing his friend's sudden obscene look, John was speechless. However, faintly, a curiosity and expectation also rose in his heart: speaking of which, he had not yet come into contact with such creatures as nobles......

……

Early the next morning, John went out after breakfast.

Today, instead of riding his own bike, he asked Hans to book a cab and head straight for a shopping street in Berlin. About half an hour later, the carriage stopped at the door of a shop.

"You wait here for me a moment."

After getting out of the carriage, John gave instructions to the coachman, and waited for the other man to agree before stepping in.

As soon as I entered the door, a neatly dressed salesman greeted me and greeted him respectfully: "Sir, is there anything I can help you with?" ”

"I need a microscope!"

Without looking too much at the surrounding goods, John directly stated the purpose of the trip.

"Microscope?"

After hearing this word, the salesman was stunned for a moment, and couldn't help blinking his eyes, and the eyes that looked at John immediately became surprised.

"What, is there a problem?"

John's heart was a little unhappy, and he asked with a cold face.

"No, no, of course."

The salesman was shocked, and hurriedly waved his hand with a smile and said, "But sir, we generally don't have displays for such valuable commodities as microscopes, I don't know if you have specific brand or model requirements?" ”

"Do you have a specific price list?"

John's brow furrowed, and he hesitated for a moment before saying. The brand and model of the microscope more than 100 years ago, he would be hell if he knew. However, he came to this shop after inquiring, and he knew that the other party was the largest microscope store in Berlin, so it was more realistic to look at the price directly.

"Of course, please wait!"

Tilting his head and glancing at John seriously, the salesman nodded and went to the counter to rummage through. It can be seen that there are definitely not many people who usually buy microscopes, otherwise this guy would not have looked for it for several minutes. Finally, the salesman took out a thin piece of paper and respectfully handed it to John.

Casually taking the quotation, John's eyes swept up, and suddenly he was full of excitement, and the whole person was in good spirits.

"This is the price of a microscope?"

Staring at his eyes, John couldn't help but swallow a mouthful of spit, only to feel that his heart was like 10,000 yaks galloping by, if he hadn't forcibly maintained his demeanor, he would almost have grabbed the salesman's collar and snorted angrily: "Are you sure that the things on this list are not an electron microscope that has crossed over?" ”

"Sir, may I have any questions?"

Seemingly a little worried, the salesman asked with a smile.

"No, no problem."

After taking a deep breath, John finally understood what the concept of a microscope was in the 19th century, and why this guy looked at himself that way. A guy as young as him suddenly came to the door and said that he wanted to buy such an expensive thing, and the salesman politely found a quotation for him, which was already quite polite. And John could guess that it should be his own set of elegant clothes that played the biggest role.

"Alas, it looks like I'm going to bleed this time!"

With a sigh in his heart, John reluctantly began to look at the quotation on the list seriously.

No matter how expensive it is, John has to buy one, which cannot be saved, because he is going to do blood research next, and the microscope is a necessary equipment. At the beginning, it was because he knew that although the microscope was very common in later generations, it was a very expensive real equipment in this era, and it was definitely unrealistic to use it at will at the University of Berlin, so he planned to buy one himself, but he never thought that the price of this thing would be outrageous to this level, and the price of any microscope would be enough for dozens of bicycles.

“1add，enham……”

Looking at the microscope's brands and quotations line by line, John's head was a little big. Not to mention that these are things from more than 100 years ago, even the microscope brands of later generations he doesn't know.

However, when John's eyes swept over a word, his eyes suddenly lit up, and he pointed at it and turned his head and asked, "Do you have this brand of microscope?" ”
