Lubitz and Oakle slipped into Dr. Nobel's room with a cautious look.

Like a shameful thief.

Dr. Nobel's room was simple and complicated for the two of them, and the simple thing was the decoration of the room, a wooden bed against the west wall, a hardwood table in the center of the room, and only a chair could be seen next to the table, perhaps Dr. Nobel never expected a guest to visit.

Other than that, there were a few rudimentary toiletries and a large number of books piled together, and the only thing in the room that could really be called decoration was a pot of flowers by the window.

All of these things take up about a third of the room, and the other two-thirds of the open space is what I call the 'complicated' part.

It was Dr. Nobel's workbench, which was filled with all kinds of bottles and cans, and if a novice who was unfamiliar with the environment used it, it would be common to miss something.

A notebook was spread out on the left side of the workbench, and on the right side of the workbench was the large stove, which was very old, but not very decayed because of its frequent use, and several iron cages were placed under the stove, and the monkeys in the cages were looking at the two strangers who had suddenly broken in with their smart eyes, with curiosity and fear in their eyes.

Lubitz noticed the monkeys first, and he exclaimed in surprise as if he had found some treasure: "Aha, what have I found?" It turned out that Nobel was not a wizard, but a circus juggler. ”

So saying, he laughed and walked over to the cage, taking a small pair of tongs by the stove in his hand, trying to tease the poor fellows.

Oakle noticed two things placed in the center of the workbench, on the left was an open notebook densely filled with characters and drawings, which looked like a notebook or something, and on the right was a transparent glass cover, and inside the glass cover was white smoke, through which Oakle could vaguely see a dark shadow lying there.

"What is this?" Oaker said suspiciously, then walked over to the workbench and picked up the notebook to check it out.

Although they are also doctors participating in medical competitions, Oaker and Lubitz can be regarded as the kind of people who fish in troubled waters, and their medical skills are still at the stage of 'all incurable diseases can be dealt with by bloodletting', so he can't read what Nobel's medical skills write in his notebook.

"What the hell, it's a mess, it's a wizard's magic book at first glance! Hum! Oakle was furious when he couldn't read the contents of the notebook, and he flipped through it casually, then threw the notebook on the table, and then turned his attention to the glass cover next to it.

Oaker turned his head to look, and saw that Lubitz was still teasing the monkeys, so he said impatiently: "Hey, Lubits, come and see what this thing is, I think the secret of that Nobel guy should be in this glass cover." ”

Lubitz was having fun, so he waved his hand casually and said, "Come on, it's up to you to see what secrets that guy can have." ”

Oaker glanced at his mouth, disdainful of Lubitz's playing with the monkey, but he was embarrassed to say that he was afraid of the smoke-covered object in the hood, so he didn't dare to open it to look at it.

The unknown is always frightening, and so is Oakl, but in the end he turned his head to look at Lubitz, and finally gritted his teeth and lifted the cover.

The cover was removed, and the white smoke that gathered in it slowly dispersed, and Oaker held the cover in his hand, and waved it impatiently with his hand, waving the smoke away.

Smack!

Lubitz was having fun when suddenly the sound of porcelain shattering sounded, knocking him down.

"Hey, Oakle, what are you doing? You know, we're sneaking in now, don't make such a big noise! Lubitz said exasperatedly, then turned his head to look at Oaker.

Oaker froze there, his mouth wide open, his eyes staring straight at something on the table, as if he had seen something unbelievable.

"What's going on?" Lubitz stood up suspiciously, walked towards Oaker, and at the same time looked at the workbench, and just one glance made him involuntarily exclaim: "Black Death!" ”

At this moment, a sense of fear wrapped around their necks like a rope on a gallows, and although they were not well-versed doctors, they still had a full understanding of the characteristics of the Black Death after being in Heidelberg for so long.

The little monkey on the workbench in front of him was covered with black patches, and there were some ulcers of varying degrees near the patches, and yellow pus was flowing from his mouth and nose.

There is no doubt that this was a symptom of the Black Death, and it was this terrible disease that terrified Lubitz and Oaker to death.

"Nobel's hidden secret turned out to be this, let's go, let's go!" Lubitz was the first to react, and then, without waiting for his companion, he turned and rushed out the door.

It wasn't until Lubitz rushed out that Oaker reacted in hindsight, and he hurriedly followed, so panicked that he even forgot to lock the door.

On the workbench, the little monkey was still lying there with his eyes closed, but if Dr. Nobel was here, he would be pleasantly surprised to find that the symptoms of the Black Death in the little monkey had been reduced much.

Soon after Oakle and Lubitz had fled, Dr. Nobel returned to the street after dinner, and from a distance he saw the door of his house open.

"Not good!" With an exclamation, Dr. Nobel hurriedly ran into the room, and as soon as he entered the room, he immediately saw the shattered glass cover and the little monkey lying on the table.

"Oh shit, damn it, they're going to come and stop me, we have to do human experiments as soon as possible!"

Dr. Nobel screamed, then immediately rushed to the workbench, grabbed a vial containing the blood of the Black Death, and poured it all down to his mouth.

Then, as if he suddenly remembered something, he rushed to the bottle of notebook placed next to him, opened one of the pages, tore it off, and stuffed it into the inside of his underwear.
