Half River Autumn Moon and River Spring [Rat and Cat]

After Bai Yutang followed Zhan Zhao back to the room, Zhan Zhao took out the paper with the medicine bucket pattern drawn on it, and after spreading it out, Zhan Zhao said seriously: "Hey, rat, I have been thinking that the murderer will It is certainly not without purpose to arrange the murder scene like this, but I have always speculated about this purpose."

Bai Yutang looked at the artwork on the table and waited for Zhan Zhao to continue.

"For example, the murderer is venting his anger, or showing off, covering up, burying...or, hinting, provoking."

"I was thinking about this case when I was on duty yesterday, and after connecting the two murder cases, I felt that the murderer was really reminding us, Yutang, this is not the end, the murderer will continue to commit crimes, and blatantly told us Where is our next goal!"

"You mean, the murderer did this to reveal to us his next target on purpose?"

Zhan Zhao nodded, then pulled out an old map, unfolded it and said, "This is a map of the capital that Mr. Gongsun drew in his spare time a few years ago. You know, maps are hard to come by. Look, do you feel a sense of déjà vu?"

Bai Yutang glanced at the map for a few times, then looked at the icon of Yaodou beside him, and said, "I understand why you kept saying that it looks familiar to you, Mao'er."

Zhan Zhao stroked his chin and said, "That's right, when I saw that Yaodou, I immediately thought of this map. Although the map is not as neat as Yaodou, there are many traces to follow."

Bai Yutang frowned and said, "But the map is obviously several times larger than the medicine fight. How can we observe the medicine fight with reference to the map, unless... there is something that can be used as a demarcation point? Delimit the range within an area , rather than the entire map?"

"Smart! There is such a dividing point!" Zhan Zhao's eyes sparkled, and Bai Yutang unconsciously looked behind Zhan Zhao, always feeling that there was a tail wagging proudly there.

Zhan Zhao tugged Bai Yutang, and motioned him to look at the map. Bai Yutang watched Zhan Zhao grabbing his hand, and thought to himself, this cat, now he has forgotten what he said about the distance of a sword.Thinking of this in his heart, he simply took advantage of the situation and moved closer to Zhan Zhao.

"What do you think the murderer would choose if he wanted to set a benchmark in the capital?" After speaking, he pointed to the map on the table.

Bai Yutang thought for a while, and inexplicably remembered the heart that was placed in the medicine bucket, the only organ.

"Heart?" Bai Yutang blurted out, looking at the numerous map marks, "Cat, the heart is the reference point you are referring to, right? The most important, the most crucial point."

Zhan Zhao smiled: "That's right, if the heart is the most important part of the human body, then the most important part of the imperial capital must be here."

After saying that, Zhan Zhao tapped the most vigilant mark on the map backwards with his fingers.

Royal Palace.

Bai Yutang nodded: "It turns out that the murderer took the palace as the center point, so the line where the corpse is placed can be regarded as the equator..."

Zhan Zhao blinked: "The equator?"

"Well, Kong Yingda, a Confucian scholar in the previous dynasty, once wrote that 'the center of the sky and the middle of the north and south poles are called the equator', so you can think of the equator as a line that runs through the east and west and divides the north and south equally."

Zhan Zhao seemed to understand but nodded his head, thinking that this mouse knows these things better.

Bai Yutang thought for a while, took a piece of thinner rice paper, and then used a ruler and a brush to draw a large "ten" character. Zhan Zhao stared at it intently, and saw that Bai Yutang waited for the rice paper to dry after finishing the painting. , and lightly stacked the paper on the map, and then aligned the center of the cross with the palace, the huge cross ran through the entire map at once, and because the rice paper is thin, the signs below can still be clearly seen Chu.

Zhan Zhao said: "Hey!! That's it!! When the proprietress said that their place is only two streets away from the palace, I felt a little strange!"

Bai Yutang smiled and said, "I know the murderer's target."

Zhan Zhao looked at Bai Yutang and said, "Tsk, I know that the open drawer with the angelica in it represents the murderer's target. I think the murderer is really a dog's angelica." According to the division, the murderer's target for the first time was on the second street adjacent to the imperial palace. However, I can only judge that the target is on this street, but I don't know how to identify which family in this street will suffer... According to the first two The owner of the pharmacy was the one who was killed the first time. Could it be that the murderer chose the pharmacy? Each grid represents a pharmacy? But the number of grids away from the equator and angelica on the second medicine map is also too many. There are so many pharmacies...and, what do you think of the second picture of the medicine fight?"

Bai Yutang didn't make a sound at first, but just turned the picture of the cross at an oblique angle, changing the picture from the shape of "ten" to the shape of "×", and then continued to align the center point with the position of the imperial palace. .

Zhan Zhao smacked his lips: "Oh, so that's the opinion! So it means that the position has changed..."

Bai Yutang said: "The positions are different, but the distance can be calculated. If I'm not wrong, the reason why the murderer used this seven-star chest is because the distance between his grids is the same, which can be converted into actual distance."

"Huh? Calculate the distance?"

Bai Yutang nodded: "That's right, Mao'er, didn't you wonder why the first time there was a whole row of body parts, but the second time there were only three spaces?"

Zhan Zhao stared at Bai Yutang intently: "Is this really particular?"

"Well, I didn't expect it before. After contacting your inference just now, nine out of ten, this arrangement is used as the scale of the map."

"scale?"

"That is the ratio of the actual distance to the distance on the map. To put it simply, not all maps have the same ratio to the actual distance. For example, some are one to five thousand, and some are one to ten thousand. If there is no way to judge, then even Knowing that the murderer killed people in this way, we still have no way to determine where the next murder scene will be..."

Zhan Zhao let out a thoughtful "Oh", and then asked, "Then how do we judge the ratio of the murderer's order?"

"It's not very difficult. In the first time, there were seven grids filled with body parts, and in the second time, there were three grids. These grids are all equilaterally the same shape, so you only need to compare the location of the first murder with the palace. Substituting the actual distance between the heart drawer and the angelica drawer on the medicine bucket here, the ratio of the distance drawn by the murderer can be calculated, and the ratio represented by the seven drawers can also be calculated. The proportions represented by the three cabinets."

Zhan Zhao blinked his eyes for a long time: "Mouse, sometimes your brain is really not as useful as normal!"

Bai Yutang sighed helplessly: "It's the cat, you just don't want to count it..."

Zhan Zhao waved his hand: "No, no, don't let me count, I can't figure it out even if I die, I'll get you some more pens and paper, I'll work hard for you today, and figure out what happens next time Where will the location be..."

Bai Yutang said, "No need..."

Zhan Zhao was stunned for a moment: "En? Why?"

Bai Yutang looked at Zhan Zhao's expression and smiled faintly: "Didn't I just say that, I already know the murderer's next target."

"Huh? So fast? Don't bring such a tough mental arithmetic, okay!!"

"Isn't Gongsun's map marked with the conversion between the actual distance and the distance on the map? As long as you know the map size of Tong'an Hall and the Imperial Palace, you can easily know the actual distance between them, and then substitute it to the distance between the first two squares of the medicine fight." The distance between each grid can be calculated, and the ratio represented by the seven grids can be converted, and then look at the second picture of the medicine bucket. Since it is a diagonal relationship, the calculation will be a little troublesome, but as long as..."

"Stop, stop!" Zhan Zhao was already starting to feel a little dizzy, "Okay, I won't go into the details, you mouse, just tell me where the murderer's next target is..."

Bai Yutang pointed to a place on the vertical palace on the map drawn by Gongsun, and said, "If the calculation is correct, it should be here, but the specific family will not be known until we get there. I don't care about this street." Too ripe."

Zhan Zhao looked at it, nodded and said, "I seldom go to this street, so I'm not familiar with it. Hey, if that's the case, then let's go now!"

After finishing speaking, he planned to pull Bai Yutang's sleeve again, but Zhan Zhao suddenly remembered something when he stretched it halfway, so he took his giant que and handed it over: "Come on, mouse, grab it and keep a sword's distance."

Bai Yutang was a little dumbfounded.

The two of them were about to go out one after the other when they saw Su Liran walking out holding Dani, followed by Su Gui who was muttering all the time. With Shibu, his complexion has obviously improved a lot, holding Su Liran's hand and jumping happily, Su Gui has been chanting "Young master be careful... Hey, little brat, don't run around... Knock my son hand... ouch, I said you brat..."

Seeing that Zhan Zhao and Bai Yutang were going out, Su Liran said politely, "You two are going to handle the case?"

When Dani saw Zhan Zhao, he laughed even more happily, let go of Su Liran's hand, and ran towards Zhan Zhao.

Zhan Zhao picked up Dani, patted his head and asked, "How is your body?"

Dani smiled until his eyes narrowed: "Enen, it's much better, where is Brother Zhan going?"

Zhan Zhao smiled and said, "Go handle the case, how about you?"

"Let's go buy medicine!"

"Oh?" Zhan Zhao looked at Su Liran who was beside him, "Hey, Mr. Su, has General Pang left already?"

"No, not yet..." Su Liran said in embarrassment, "He is helping Gongsun dig the ground..."

"Eh?"

What is this development? !
