Berlin, afternoon, Robert Koch Institute for Infectious Diseases.

Dr. Emil Adolf von Behring and Dr. Shibazaburo Kitasato looked at each other helplessly with big eyes and small eyes. This is the first time that Dr. Behring has repeated the serum test for diphtheria since returning from the Imperial Palace, but none of them have been able to replicate the success of Prince Waldemar.

Beilin looked at Beili through the protective mask, and said in a sullen voice, "Beili, I really don't know what happened, why can't the success of the last time in the Tai Womb be replicated?" Could it be that it wasn't the serum therapy that worked to cure diphtheria last time, but the prince's own ability to heal himself? ”

"To be honest, Emir, I still think that we should first find out what the virus that causes diphtheria looks like it, and then consider isolation, and strive to cultivate a pure diphtheria virus, and then conduct experiments." Kitasato Shibazaburo replied.

"Dangdang!" There was a knock on the door of Dr. Behring and Dr. Kitasato's laboratory, and he shouted, "Emir, Kitasato, Professor Koch is waiting for you in the office, and he told you to come right over." ”

When Behring and Kitasato changed their clothes and hurried into Professor Koch's office, they saw a gentleman and Professor Koch signing a document at their desks, and next to them stood a teenager dressed in British style.

Joey saw the two of them walk in, and walked up to greet them with a smile, "These are Mr. Behring and Dr. Kitasato, I'm Waldemar, you can call me Joey." ”

"Hello, Joey." "Fortunately, Joey."

The thinking of these two doctors has not yet come out of the failed experiment just now, although Behring feels that Joey is a little familiar, but he doesn't think about who Joey really is, just treating Joey as a child of Professor Koch's acquaintance, and Kitasato is even more so. After a casual greeting, the two doctors walked straight to the sofa next to them and sat down.

But seeing this scene, Professor Koch couldn't sit still, put down the pen in his hand, got up and walked over, pointed to the two doctors and introduced to Joey, "I'm sorry, Your Royal Highness, please allow me to introduce my student, this is Dr. Emil Adolf von Behring, who invented serum therapy to save you, and in serology and immunology, he is one of my most proud students." This is Dr. Kitasato Shibazaburo, from the Faculty of Medicine at the University of Tokyo, Japan, and like Emir, he studied serology and immunology, and he is one of my most proud students. ”

Professor Koch then introduced Joey to two of his students, "This is His Royal Highness Prince Joachim Friedrich Ernst Waldemar, the son of Crown Princess Frederick, our institute's patron. His Royal Highness the Prince is here today to thank us for the treatment of diphtheria in the past, and to bring a new funding contract. Professor Koch glared, already stunned and bewildered, "Emir, watch your manners. ”

Behring's faux pas is for a reason, Behring has not made any progress in the previous nearly 2 years of research on serum treatment for diphtheria. It was only after learning from Professor Koch that the child of the institute's sponsor had diphtheria, and the treatment of three consecutive cases of diphtheria guinea pig samples was suddenly successful.

However, in the week after returning from the Taiwo, no matter how hard Behring and Kitasato tried, they could not reproduce the success of the past, and the experimental guinea pigs died one after another, and the guinea pigs killed this week were almost catching up with the previous year, and now Behring and Kitasato are nicknamed the guinea pig terminators by their colleagues at the research institute. A series of failed experiments was already extremely stressful, for fear that because of his own trial error, he would take credit for saving the prince, and the institute would lose the patron of the crown princess and close its doors.

Now that the prince had even come to see him in person, Behring now felt a little like the horror of the victim standing in front of him after his attempted murder.

When Professor Koch told Behring that the Prince, on behalf of the Crown Princess, would give a new grant to the Institute, especially for his research, Behring's nerves were on the loose.

Looking at Behrin in front of him, he cried in a choked voice about his failure experience, and thought that the success of the last serum treatment was probably an illusion, and in fact, His Royal Highness the Prince's recovery was based on his own self-healing ability. Professor Koch really couldn't sit still, as a staunch German patriot, he had just promised Prince Waldmar that as the best microbiology research institute in Germany (in fact, the world) fully funded by the crown prince, he would definitely leave the research laurels of immunology, serology, and virology in Germany, and would definitely not let that Frenchman Pasteur lead Germany.

"Emir, failure is not terrible, the most terrible thing is the loss of one's own confidence. I have always been convinced that there is nothing wrong with your serum research, don't care what others say, stick to your own experiments, and any help you need will be supported from me. Professor Koch patted Behring on the shoulder and encouraged.

As a psychology student in his previous life, Joey had been exposed to clinical medicine when he studied neuropsychology, and he was already familiar with the famous Professor Koch and several of his famous students, and as a German medical person, he had long been familiar with the history of Deling, and seeing this, Joy decided to help Dr. Behring, the first Nobel Prize winner in history.

"Dear Mr. Behring," said Joy to Behring, who had almost stopped crying, "I once heard Mr. Paul O'Ellich propose a concept at a science salon organized by my mother, as if it were least lethal. It seems to be said that in a group of experimental animals, the lowest dose and concentration of the drug caused the death of individual animals. ”

Professor Koch, Behring, and Kitajima suddenly felt a light light light in their minds. Professor Koch excitedly grabbed Behring, "Go, Paul is in room 207, tell him to come over right away!" ”

The rest of the story, just like history, Professor Koch and his three great students (all of whom are at the level of the Nobel Prize) finally sat together, and under the guidance of Professor Koch's Koch rule on the basis of which the pathogen was judged, Dr. Behring's "antitoxin" found in animal serum, through the bacterial culture method invented by Dr. Kitajima, and finally according to Dr. Ulrich's principle of minimum lethality, the development of diphtheria antitoxin finally rushed on the right path.

Sir Ernst von Stockma, the Crown Princess's private secretary, accompanied Joey to visit Professor Koch today as the Crown Princess's representative, and signed a new funding contract with Professor Koch at the request of the Crown Princess (which was actually Joy's request). Stockma watched as Joey and the famous Professor Koch and his three young disciples were discussing medical issues they didn't understand.

Stockma always found this picture very strange, and when it came to advanced scientific questions, even a young prince could participate.

In Joey's eyes, this is not the case, and he is so excited to sit next to these four great figures of the nineteenth century who changed the fate of mankind. In addition to being excited, Joey did not forget to use his later life experience, whenever these great figures were a little stuck in their discussions, he could always interject appropriately, and return the great shining points of these great figures on the road of research to these great figures in advance.

A clash of minds that history should have played out at the Robert Koch Institute in 1894 began 15 years earlier, and Joey was immensely proud to have had the privilege of being a part of it.

The discussion went on until late that night, and of course Joey couldn't last that long. It was nearly supper time, and after Joey had hastily had dinner prepared for the four of the big men who were in a heated discussion, Joey was caught in the carriage by Sir Stockmar and returned to the palace in Berlin.

Sitting in the carriage, Joey clucked and laughed as he held the new funding contract he had just signed that afternoon.

Sir Stokema looked at Joey and couldn't help but smile and ask, "Joey, you look like you just stole the dragon's treasure, how can you be so happy?" ”

"My dear Uncle Ernst, when I heard this morning that my mother had sent you to deliver Professor Koch a new cheque for the grant, I realized that she was funding a treasure, so I insisted that I come with Uncle Ernst to Professor Koch in the afternoon. On the one hand, I would like to thank Professor Koch and Dr. Behring for saving my life, and on the other hand, I hope to use this new funding contract to help my mother dig up a big treasure. Ha ha! I didn't expect to succeed, Professor Koch and his students are here! Joey said to Sir Stockhorse with a smile.

"You may not know what this contract represents! Let me tell you this, diphtheria, anthrax, tuberculosis, cholera, tetanus, and even syphilis will all be cured from now on. This contract in my hand is the key to healing them, and it also represents wealth..., the treasure of the dragon... Well, at least 10 dragons' treasures are the limit of my heart. Joey patted the contract in his arms hard.

"The treasure of 10 dragons? Joey, right in this contract, which you only spent a morning on? ”

"Dear Uncle Ernst, I also want to ask for your forgiveness, I am very sorry, I will say in front of my mother when I go back, this contract was actually written by you who taught me, after all, I don't want to be a genius at such a young age."

"Ah, Joey, what are you talking about!"

"Genius idea!" When Professor Robert Koch woke up early the next day and recalled the details of his academic discussions with his students last night, he suddenly discovered that the focus of several of the issues they had discussed had been initiated under the guidance of Joey's ideas. Professor Koch recalled Joey's performance and exclaimed, "What a genius this kid is! ”
