"That's really ...... Surprising. ”

Kraft finished reading the letter in front of his hand and handed it to the curious Lucius.

They were sitting in Professor Kallman's room, the same one where the three of them had enjoyed barley tea and biscuits together when Kraft first arrived. While Kraft was checking the letters, Lucius boiled a jug of water on the small stove and added two new cups of barley tea to the table, but he could not find the professor's honey jar.

After a month in the castle, Kraft was finally driven back by his grandfather to take up his post. After arriving, I rested in a hotel for the night, and the next day I was going to come to the college to ask for details and then consider long-term housing.

Not long after entering medical school, he was stopped by an unknown student who claimed to be a friend of Lucius. Seven days earlier, Lucius had told them that he had taken the trouble to inform Lecturer Kraft if he had seen him.

Kraft followed the student through the twisting corridors of the medical school, up the spiraling steps, through several arches, and finally in the professor's private room, where he found Lucius, who was worrithed over a table of papers.

I have to say that this building of the medical school is quite complicated, and it is not the first time I have been here, it may be that there are too many meaningless decorative columns and shades, and each floor uses different space allocations, and I feel that the path is different every time I walk.

After bringing Kraft with him, the student took his leave and left. Lucius put down the half-arranged paper in his hand, took out a formal letter sealed with fire paint from the inner pocket of his black robe, and handed it to the dazed Kraft with the excitement of waiting for a long time.

"Mentor Kalman trusts your talent and passion in this area." Lucius's impatience was written on his face, "Since there are two of us now, we can continue to refine the study of the black liquor before he returns, according to the arrangement of the mentor." ”

"Thank you, Professor Kallman, for your trust, but I'm still a little confused." Kraft reached into the bottom of the envelope and found a brass key, apparently he didn't have to worry about housing for the time being.

Although they had not known each other for a long time, Professor Kalman seemed to be quite optimistic about himself, willing to share such an important thing, and also handed over valuable samples and experimental results to himself. Kraft was very touched by this, and it was completely reasonable that he could help as much as he could.

According to the description in the letter, it was difficult for him to imagine what this thing, which had been almost identified as "black liquor", corresponded to in his own knowledge system.

white fluid, which can be thought of as cerebrospinal fluid; Yellow fluid, which basically corresponds to bile, is undoubted; Red liquor, of course, is blood. But this black liquor, what is it is really confusing. And judging by the meaning of the letter, they are probably also extracted from some tissue in the human body, and after extraction, they can be stored for a long time and retain their properties.

What's even more outrageous is that I don't know if the container is strong, or if this thing has stabilized to an outrageous level, he actually sent someone to carry it in his pocket and brought it from Dunling to Wendeng Port? This so-called "inhibition" nature is a question mark for Kraft, and it is estimated that it will only be known by seeing the detailed experimental records.

So, according to the letter, what we now consider to be "black liquor" is indeed extracted from the human body. ”

This scene makes it difficult for Kraft to imagine, what is "extracted" from the human body? Here, the word is generally used to make another liquid from a liquid such as liquid medicine or alcohol by distilling it by heat, or by standing and the like. The second half of "Body Fluids" is more like to be used, but it is used to take some ingredients from medicinal juices and decoctions and give people to drink to "regulate the balance of body fluids".

Anyway, it doesn't feel right.

"I remember the professor saying that the church over there is very strict and that there is not a chance to do this kind of thing." Kraft said. The professor had complained to him that there was no way to do anatomy on Dunling's side, thanks to the church's influence there.

"I don't know." Lucius didn't care about this, after all, he had been studying in Wendengang, and he was with Professor Kalman, and it was not a matter at all to find a corpse for a secret autopsy, "Mentor's mentor, I mean Professor Morrison, is not an ordinary person at Dunlin University, there will always be some way, right?" The mentor hasn't been back to Dunling for a long time, so he should have found a way over there over the years. ”

Kraft used his powerful memory to think again, but he still couldn't figure out how to make such a liquid in the human body.

He strongly suspected that it was an instrument issue that caused them to inadvertently make some toxic liquid. Maybe it's because there are heavy metals in the raw materials used to make glass instruments, and they are mixed in during the heating process. Then, Professor Morrison, who had no sense of experimental safety, fed the sample to the animals, or simply tasted it himself with a fearless spirit.

It makes sense, heavy metals or other neurotoxic things are stuffed, and the central nervous system inhibition is not coming. It may be a series of symptoms of dizziness and weakness, which soon manifest itself in animals and people.

Isn't this a strong inhibitory effect?

"Well, Lucius, before I go to see the real thing, I want to ask how much it is, and what is it for?" Kraft took a closer look at Lucius' face and assessed his mental state. Except for a little excitement, there is nothing wrong with it for the time being.

Lucius gestured with his hand to the size of his thumb and forefinger circled: "It's just a round glass bottle, brown, with only one bottom in it." During the experiment, the professor dipped a small stick in a little bit and dissolved it in water.

Why don't I take you to see it directly, the sample is in the basement of the academy. We dissolve a little bit in a glass of water, and people fall into a deep sleep after taking a small sip. ”

"You still give it to others?!" Kraft was shocked, the most he knew about the ferocious operation of swallowing Helicobacter pylori alive was nothing compared to this.

"No, it's just that my mentor and I took turns trying, and absolutely no one else here knows about its existence." Lucius's focus was obviously completely different from that of Kraft, and he excitedly stretched out his hand to show Kraft a few red dots on it, "It's amazing, it's so little, after drinking it, you will fall into a deep sleep, even your heartbeat and breathing will slow down, and you can't wake up with a needle prick." It would be about a day before I woke up, completely unaware of what had happened during that time. ”

"Huh?!" This kind of operation is completely beyond Kraft's imagination. The bravest record in his two lives combined, most of the days were in high school chemistry class, because he was curious to smell the gas made by his group.

Personally taste and drink a sip of the unknown liquid that you have slept for a day, or take turns to drink it, this behavior is on the same level as the gambling dumb fire in Russian roulette, or even surpasses. If he did this, he could blow a few words to Meng Po before drinking soup at the bridge, and the devil in hell would be impressed when he saw it.

"Sit down." Kraft pushed Lucius into his chair, "I'll check it for you, don't ask why." ”

While touching Lucius here and there, he was closely interrogated: "How long ago did you drink?" How many times have you drunk? Are there any other changes after losing consciousness besides decreased heartbeat and breathing? Did you feel any discomfort after waking up? How's your spirit lately? Has there been any change in food intake? Did you sleep well? Is there any abnormality in the bowel and bowel movements? ”

"No, everything is normal." Lucius was shocked by his sudden seriousness, "According to the "Humorology", as long as the liquid in the human body does not have a tendency to change to black liquid in large quantities, a small temporary increase in black liquid is a temporary change. The professors are all right, how can something be wrong with a younger person like me? ”

"!" Kraft gave him a head-to-toe physical examination, and nothing seemed to be out of the ordinary. The simple examination did not reassure him, but only made him more vigilant.

A very small amount, taken orally, has a rapid onset of action, loses consciousness for a day, and the pain cannot be aroused. A little suspicious, he even began to wonder if Lucius's current excitement was an anticipation of continuing the experiment, or a sign of a mild personality change and mental abnormality.

Kraft took two steps back and re-examined Lucius, his gaze sweeping over him from head to toe. From his brown hair, to his slightly pale countenance, to his hands with a few red dots, and finally to the paper he was sorting out when he entered.

Pale yellow paper covers most of the tabletop, and most of the handwriting on it is slightly scribbled but beautiful, and the typography is more casual. The font size on different sheets of paper is different, so it should not be written together. Some had been stacked on top of each other, and the rest were scattered around in a chaotic manner, leaving only the teacups containing barley tea to sit on the edges.

"What are these?"
