It was a time when knowledge was quite valuable, and the Church was not generous enough to allow outsiders to enter its library and look through it at will, so the work of consulting the literature was still entrusted to Father Green.

It was not until the professor had left that the priest had just opened the first few pages of a long-lost book on heraldry, previewing the basic patterns of the patterns and preparing for the reading of the original document. There are still a few all-nighters and a finger hairline away from practical use.

As for the matter of turning over the genealogy of the king's eighteen ancestors according to the request, it is even further away. For the sake of secrecy, this can only be done by him.

However, Green was one of the best graduates of the church school, and Kraft was optimistic about his ability to learn, believing that he would be able to make satisfactory progress before his pre-experiments were completed.

Yes, pre-experimental.

The absence of ideal conditions does not mean that there will be nothing to do, and it is perfectly feasible to carry out some exploratory experiments on a small scale.

Of course, you can't do it in a clinic. Downstairs is the outpatient clinic and hospital room, next door is the kitchen and dining room, and there is not even a reliable basement, and Kraft would be crazy to try dangerous operations in such a place.

It has to be a place that is relatively safe and robust, and that no one disturbs you.

It's really hard to find, the professor hesitated all the way, and suddenly remembered what the title was added after his name - and immediately rushed back to the university to ask for a laboratory.

In view of the fact that the trial court came and went from time to time, seriously disrupting the normal order of the medical school, everyone moved the items suspected of violating the rules one after another.

With this move, there will be nothing left. The upper laboratory of the main building was deserted, and the rats shook their heads when they saw it.

And someone who is in a different situation has discovered this blind spot.

"No, I don't involve human experiments at all, I just do some research related to physical property changes." That's how he explained it to the person in charge, anyway, that's the case, "Don't worry about the trial court inspection." ”

- I should come to inspect the progress of the work of my accomplices.

Kraft took Koop and moved a bunch of his belongings into the newly allocated territory, one of the largest spaces outside of the burned Dome Hall.

Yvonne insisted on following along, taking over the task of carrying a box of heavy utensils, and as he took it out, he was unsurprisingly nervous and overforced, and accidentally crushed two pieces. Because of the process limitations, the glassware is not so thin, and in her hands it is no different from a breakfast egg.

Considering that she already looked depressed, Kraft wisely removed the original price by a zero, and persuaded her not to care about the little things.

Even if the table was moved again, the girl could not get rid of the clouds, and a frustration of "I didn't do anything" accompanied her back to read.

"Maybe Yvonne should be kept away from these things for a while, after all, her situation is special." Koop persuaded. He knew part of Yvonne's condition, at least the part that had changed on the surface.

Kraft watched Yvonne descend the stairs, get into the carriage back to the clinic, and turned to move a table back to its original position, "No, the more times like this, the more you should give her something to do, even if it doesn't make sense in itself." ”

"Giving her the confidence that 'I'm already good,' rather than pushing for short-term results, pushes people in directions we don't want to see."

"What's more, Yvonne is already very good. At this age, I was still trying to skip class to catch birds in the woods, and she already had a strong sense of planning for the future. ”

"You still skipped class?" Something remarkable has undoubtedly been leaked.

"It didn't work out, after all, my teacher only taught two people." No one can disappear silently on Old Wood's turf, and those who are captured are generally taught in the traditional way.

"Let's start quickly, as the saying goes, start early, finish early, and eat early."

Kraft poked his head out of the window to make sure there was no vantage point around him to observe it, half-closed the window pages, and lined up the table with large and small utensils.

The most important experimental materials were locked in an iron box, and a small, permeable wax-sealed glass bottle was kept in the center of the stuffed cotton.

The crystalline granular material rubbed and rolled in the bottle, making a small sound like a horned viper swimming through the desert, like a jar of black salt whispering.

Kraft gently shook the bottle, smoothed the surface, compared it with the height line carved on the bottle, and then used tweezers to pick out a relatively large one and put it in a large round-bottom flask.

He first tried to slowly warm up the water bath until the water boiled in the trough and the crystal did not change much, completely ruling out the possibility of melting at the temperature of the animal's body temperature level.

Heated by a candle flame, the subject remained unmoved, as if it were a real grain of sand or salt, but dyed with an extremely pure black, as if a needle had poked a hole in the space.

Then, various solvents, including pure water, acids, lyes, and oils, take turns to take effect. Not surprisingly, if it could be dissolved so easily, there would be no need to convert into a liquid at all.

The physical and chemical properties of black salt are quite stable, and it belongs to the die-hard school that is suitable for being classified into "impurities".

This is a good thing, which means that if it leaks into nature, it will be deposited steadily, rather than liquefied and followed the water cycle everywhere.

"We're going to take it a step further." Seemingly due to the lubricating effect of the liquid, Kraft clamped it twice before getting it out of the oil, "Then you need to simulate its contact with living things." ”

"Are you going to feed it to that rabbit?"

The rabbit was transferred from the kitchen, one of the trophies of the chef at the market this morning. When he learns that he needs a lab animal, Coop's favor gives it an extra life, but now it seems that this luck has run out.

"Not so fast, and I don't want to look for a grain of black sand in its digestive tract afterwards, so let's get blood first."

The professor expertly pricked a drop of blood at the end of the rabbit's ear, scraped it off with a piece of glass, and began to observe it on the black particles. The animals, which are not yet aware of the approaching deadline, are focused on enjoying the welfare leaves, and only make a snorting sound when the skin breaks.

Under the close gaze of two pairs of eyes, the red droplets gradually dried up and solidified at room temperature, forming a thin film covering the surface of the crystal particles, and nothing happened

Kraft blinked, letting the tears wet the dry sclera.

Unfortunately, the rabbit ear was injured again, contributing a second blood to prove it invalid. The results were clear, and the sample did not react significantly to the blood.

The not-so-obvious grunt of the gastrointestinal moir reminded him of the passage of time, and it came from Koop, who was embarrassed to hold his stomach and say that he didn't care about the little accident, but it was an indisputable fact that the meal was indeed gradually approaching.

"Well, today's attempt is over, and the lack of change is also a result that proves that we don't have to worry too much about it."

Sticking out the tweezers again, Kraft prepared to clip the crystal into a separate test tube and wait for tomorrow to process it.

However, the pellet slipped between the temporal teeth, fell back into the glass and rolled several times, almost falling into the gap between the wooden planks of the tabletop, but fortunately the experimenter's good reflexes stopped it.

Kraft tried again, and his dexterous hands finally noticed that it was getting easier.

He erected two surgical mirrors to reflect sunlight onto the crystal, and looked at it more closely, and the edges and corners of the crystals that were distinct when condensed seemed to be subtle dull unconsciously.

"When?"
