Chapter 56 second quarter

Ukai triumphantly continued to lobby. "Actually, I haven't actually seen it, but I know that the "Colonnades of Spada Palace" is a well-known optical illusion building, and this greenhouse is the result of applying it. Mr. Police Department, isn't that right?" "The one you were talking about, Spada or something. What is it? Coffee shop?" "You're talking about Starbucks, but there's no branch in this city." It is true that there is no Starbucks coffee shop in Cuidichuan City, and there probably won't be any in the future. "I'm talking about the 'Sparta Palace'. The so-called 'Sparta Palace Colonnade' is... Eh, Mr. Police Department, you made this mechanism without knowing it?"

"totally no idea." "It's surprising. If this is the case, there is no room for me to express it. Please continue to explain, Mr. Police Department. It is very interesting." Ukai decided to watch from the sidelines.It seems that he knows the secret of this magic trick, but Shiki has no clue. "Well, police department, what's going on here?" "Trying to experience it yourself will come faster than explaining it. Shiki, you go in and take a look on behalf of everyone." "Uh, ok, I'll go in then." Zhimu followed the order and entered the greenhouse with trepidation.Other relevant personnel looked at Shiki from the entrance probe.Sensing the curious eyes of everyone behind him, Zhimu cautiously walked into the depths of the greenhouse step by step.

No suspicious spots can be seen near the entrance, it is an ordinary greenhouse.But as he walked forward step by step, Zhimu felt something was wrong. First of all, there is a sense of oppression that is unknown, and this feeling becomes stronger and stronger. In addition, I don't know how to describe it, should I say acceleration?Obviously the forward speed is not fast, but Zhimu feels that his body is moving forward quickly.At first I thought it was an illusion, but after taking a few steps from the entrance, this feeling turned into conviction. The relevant personnel at the entrance also made commotion one after another.It seems that they also saw that the inside of the greenhouse was not normal.

Zhi Mu stopped and looked up, the top of the greenhouse was right in front of his eyes.Shiki doubted his eyes. Strange, when did I grow tall enough to touch the top?Isn't the inner height of the greenhouse two meters? Of course it is impossible to grow taller.Shiki's height was the average height of Japanese people yesterday or today.In this way, there is only one possibility. It's not the height that gets taller, it's the top that gets lower. Shiki reached out to touch the top, showing lightly that the top here had become very low.People at the entrance exclaimed. Shiki continued to move forward, and then his head completely touched the top, so he confirmed that the top was getting lower as he went deeper.

No, not just the top.Shiki thought again that this was a greenhouse.To put it simply, the greenhouse is a semicircular tunnel. Since the top becomes lower, it undoubtedly proves that the radius of the semicircle also becomes smaller.So except for the top, including left, right and oblique, the 180-degree semicircle becomes narrower as it goes deeper, and this is where the sense of oppression I felt just now comes from.It's not that the radius is suddenly shortened when you walk somewhere, but that the further you go step by step, the smaller the radius of the semicircular tunnel will be.

In other words, this greenhouse is a semi-conical tunnel. Then Shiki remembered.They found fantastic aluminum pipes at the farmhouse during the day yesterday.According to the size and shape, it is just like the skeleton of a greenhouse, but the radii are all different.They failed to find out the purpose of these semicircular aluminum tubes yesterday. Today, Shiki can easily assemble these aluminum tubes in his head.Since the radii of these semicircular aluminum tubes are all different, as long as they are arranged in order according to the size of the radius, and then covered with translucent plastic sheets, this kind of semi-conical greenhouse happens to be formed.

The Sunagawa police department should have assembled the skeleton for this experiment, and Shiki himself is in it now. Shiki continued to walk deeper.The top is now so low that you have to bend forward, the height here is about 160 cm. Going forward, the final height of the top is about 215 centimeters, and the width on both sides is about two and a half meters.Shiki recalled that among the semicircular aluminum tubes found yesterday, the smallest radius happened to be this size. The top of the entrance is two meters high and four meters wide from left to right, so when you walk here, the radius shrinks by 75 centimeters.

This semi-conical tunnel ends here, that is, to the exit. The exit and entrance are also sliding doors and are fully open.In addition, there is a large beckoning cat at the exit, almost blocking the entire exit. This scene is almost the same as the exit of the greenhouse where the crime happened. However, here is an exit but not an exit, a fake exit. Because this exit is only a little over 100 centimeters high, only elementary school students in the lower grades can walk through it.The beckoning cat located outside the exit, even if it is definitely not a small beckoning cat, is not at all the height of an adult.

This beckoning cat is about 100 centimeters tall, as if the adult tall beckoning cat in front of the main entrance was shrunk down.Shiki has an impression of this lucky cat. It is not placed at the front entrance, but one of the two lucky cats placed at the back door. Then, Zhimu looked at the other end from the slight gap between the lucky cat and the false exit, which was also an empty space surrounded by plastic sheets, and there was another exit in the distance.That's the real exit, and there are no adult Lucky Cats out there. However, no one is right.It must be that the Sunagawa Police Department moved to other places in advance in order to perform this magic trick.

Shiki who walked into this greenhouse turned around for the first time at this time. He confirmed with his own eyes that the faces of the people at the entrance were so large that he was surprised.Then Shiki counted the width of his steps and the number of steps, and returned to the entrance of the semi-conical greenhouse again. The length of the greenhouse was supposed to be about 20 meters, but as expected, the fake exit was only 10 meters away from the entrance. Shiki finally understood the secret of the Sunagawa Police Department's magic trick. "How about it, Shiki, do you understand?"

"Yes, Police Department, I fully understand. In other words, a ten-meter-long semi-conical greenhouse is hidden in the twenty-meter-long greenhouse."
