"What is this?"

When he arrived at Kraft's attic, Lucius found patches of mottled patches nailed to the wall, lining up from the corner to the doorway.

The black and white diagram is dotted with small squares that fit together in a narrow and winding gap, but most of them are almost glued together. However, careful differentiation can still be found by the density of diagonal lines painted in the blocks.

Craft's hearing this showed him the large stack of papers in his hand, which was the result of their most of the past month, "I have filled these in on the map, and it would probably be more intuitive to represent them with images." ”

"White means better?" Lucius examined the map for a moment, questioning.

"No, it's the opposite, the black ones are the ones that get better."

Kraft handed the paper to Lucius and pointed to him the small cross and horizontal line on it, "I call it a positive effect, and a single horizontal line is negative, or invalid." It doesn't matter what you name it, you just need to remember that the former is blacked out on the map to indicate how much better. ”

"For each extra one, I draw more diagonal lines and black them in the corresponding small frame. Since they don't have accurate timekeeping tools and rely on subjective judgment, the credibility of these data ......"

Lucius scratched his head, he felt that there might not be anything more accurate than the subjective feeling of the patient. In the simplest of terms, I know my body best, don't I?

Kraft flipped through a few pages and pointed out the stranger ones from the previous days' records, "especially these ones, which change a lot from day to day, and jump back and forth." It is not ruled out, but it is too much. ”

"Look at this, we all came back with water when we went yesterday, and told us that we had just woken up. Obviously, the nearest water intake point is far away. ”

Lucius continued to scratch his head, the new well was not yet finished, and it would take quite a long time to go back and forth from the nearest water intake, which was of course problematic. It's just that he doesn't understand why anyone would do it.

"If he lied, I don't understand why he did that. What's his name? Glancing at the record on the paper, he couldn't make out what the name Kraft had written.

Kraft's first-hand records are rarely seen, and most of them are usually seen on paper that has been copied and arranged for the second time, and it is difficult not to suspect that it is because of the sloppy handwriting, which is only for the writer himself to rewrite afterwards.

Kraft glanced at it and replied without hesitation, "It's called Coop."

"Huh?" Lucius was puzzled, and looked at the name again with flying strokes and great artistry, but still couldn't read it.

"I specially opened a separate piece of paper to write down the individual differences, and then marked the picture in blue, this is just the most outrageous in it." There's nothing Kraft can do about this situation, "The best thing to do is to spend more time." ”

Lucius flipped the paper in his hand, the weight of which he couldn't believe was a little bit of their visit, "Can you still squeeze out time?" ”

"It's too hard. Maybe they all have their own reasons, but I can't figure out why one by one, and if I do, I won't be able to solve it in a while. ”

Looking at the maps on the wall, the black parts are expanding and thickening in a relatively uniform degree.

After the water was deactivated, the first survey only added sporadic sparse lattices to it. On the third day, the map changed significantly, like a handful of black beans sprinkled on it.

This trend became evident after that, and the whole area slowly improved, and most of the lattices were filled with a little diagonal line, becoming plump. For the first time, black was so pleasing to the eye.

"So the presence of black liquor in the human body is really not permanent, and if it is poured into the well water, the dilution will be reduced after a period of time after it is stopped. By analogy, those who have used a normal dilution will probably get rid of this possibility completely after a long enough time. ”

As expected, an even improvement is taking place, and most people can see a clear trend towards a gradual shift in wake time.

This also made Kraft and Lucius more and more trusted and popular in the Salt Tide District. They don't get paid much, but the change in attitude is visible.

From obedience to the authority that comes with force and status, to true respect. Some people are beginning to be willing to share more details with them, talking about the position of the sun when they last woke up and comparing the height of the opposite roof.

Admittedly, much of the information wasn't particularly useful, but quite a few were converted to help Kraft correct his own investigations.

"That's good news." Lucius said. He watched as Kraft picked up the pen and filled in a few more squares in the new drawing, picked up the information on the table and numbered it, and found that there was no discrepancy.

"It's terrible......"

"What?"

"Your memory." Lucius sighed, "I thought you memorized those secretaries word for word because you had memorized them long enough, but I didn't expect your memory to be so good." ”

Kraft couldn't answer this, so he could only say, "Probably talent", which made Lucius let out a jealous tsk.

Since Kraft didn't need help, Lucius was bored and looked at the drawn map alone.

Things presented in a simple diagram do have a different feel, and are more intuitive and easy to understand. He understood this when he read about the anatomy of the inguinal canal.

The author used a few minutes to explain where the aponeurosis and fascia came from, how they formed the front and back upper and lower walls that were extremely tongue-twisting on the back, and then explained how the contents of the stomach escaped from this structure.

All of them add up to a picture that is not as simple and straightforward as a picture. So everyone likes diagrams, especially concise and clear diagrams, and Lucius is no exception.

He started from the corner of the wall and looked at it in turn, watching the black gradually spread out, from less to more, and in reverse enveloping a few lighter colored areas.

The few pale patches are visible in the next image and are then dissolved by the new black patches.

There were also some completely untouched white lumps dotted with inconspicuous blue paint, presumably the patients Kraft spoke of who could not be sure of the truth of the statements, and received special attention.

Some of the blue dots have been removed over time, but there are still a lot of them stuck in various places, and it makes you feel uncomfortable when you look at them too much, and people want to pick them out.

There are some things that you can't get out of your head once you notice them. Lucius's attention involuntarily drifted to the blue dots, noticing the changes around them. After looking at it like this for a long time, he really found some rules.

It stands to reason that the overall staining order should be uniform, so there will be no pale spots that have been there for too long.

But there is a difference near the blue dot, not the difference caused by one or two surveys, but persistently.

At first, it is not noticeable when there are many white patches, but after most of them are blackened, it will gradually become prominent.

"Huh?"

For the sake of rigor, Lucius walked back to the previous few photos and repeatedly compared and affirmed his findings.

There seems to be a lag in the darkening of the patches around the anomalous blue dot, at least about two days slower than the approximate average rate of change, which is the time between surveys.

"Weird?"

I went to the table and drew a few pieces of tissue paper, traced the general outline of the light area, and marked the position of the blue dot in this area.

"Kraft, can you draw this place first in this picture?" Lucius pointed to the area he had found near the center of the map, roughly demarcating the area, "I have an idea, but I'm not sure. ”

The interrupted Kraft glanced at the corresponding data on the plot he circled, as if he was not so surprised, "You also think that the color change of this piece is different?" ”

"You already knew?" Lucius was a little disappointed, he thought he had found something amazing.

"I can't say that, in fact, this phenomenon has occurred in several places not only here." Kraft walked along the wall, pointing out on the map several small pieces that Lucius hadn't just discovered, deeper and shallower, and there were not a few with blue dots.

However, most of them did not last long, and disappeared in a few days, and it turned out that it was the deviation caused by the neighbors' preference to communicate with each other, which affected both subjectivity and expression. And this piece has only recently become apparent. ”

"Well, it's me who is rare and weird." With his hands spread out, Lucius put down the paper.

The paper was taken by the other hand, "You have that blue dot as the center?" ”

"Yes, because I'm looking around the blue dot. I know the two probably have nothing to do with each other, but if you want to blame them, they're too conspicuous. ”

Kraft leaned over for a moment and continued to work on the map, quickly completing a new map of the area on his own.

"It's not for nothing, Lucius."

A new rough stroke of the tinted area is drawn and stacked onto the previously drawn paper, aligned with the middle dot.

Kraft held a few pieces of paper out into the sunlight, and the intense light cut through the thin paper that cut corners and stacked the figures on top of each other.

"It's true that this area is decreasing, but it's basically shrinking around this point...... Doesn't seem to be easy to explain? "I took the pen and made a comparison, and the progress in all directions had a similar trend, and there was no black block that bloomed in the center.

"Because this person not only doesn't believe in you, but also speaks ill of you to the people around him?" Lucius drew inferences from one another, and immediately drew answers from interpersonal relationships, and his learning ability was very good.

"I'm glad you've learned one of the important influencing factors of investigation bias, but forcing analogies is not advisable. Remind me to ask more over there next time, okay? ”

"You're so modest, I don't know anyone who can remind you of what you have forgotten, except for forgetting to eat." Remind Kraft that few people do it, and Lucius doesn't think he's going to be that exception, just listen to that.

"That's right." He tapped on the blue dot and asked curiously, "Who is this person, and he is still creating false information on this website." ”

"Koop, that's what I said earlier."
