“555…… Hello, these two guys are so scary. Pen & Fun & Pavilion www.biquge.info"

Cha Mi Yu and Huan Weibo: What did we just do?

"All in all, let's see what these tips mean," Mr. Huan said, "and we've been delayed for a long time." ”

Hearing this, Liang Qiutao stopped his comforting words and came back to burn his brain cells with everyone.

“…… So, what exactly does all this mean? ”

Cha Miyu nodded to the floor under his feet: "'-x' and 'y' should symbolize coordinates. ”

"Yes...... "Liang Qiu Tao also looked at the floor, "The floor of the botanical garden is just separated by a cross, and then a small floor tile is just enough to hold a flower pot...... So this is a grid coordinate system? ”

"The rest should be an arithmetic problem that tells us which floor is the grid coordinate system," Mr. Huan said, "so that the answer is obvious." ”

"Hmm...... There is no 4th floor here, so the equation should be 3-2=1," Liang Qiutao said, "and then the position is the third quadrant (-x,y), so the coordinates are (-6,4), and the final answer is really simple!" ”

"Next...... I just had to answer one more question. ”

Although Cha Miyu said so, she didn't know what was going on, and she always felt that it was not the right answer.

It's not that there is any evidence to prove that Liang Qiutao's statement is wrong, it's just that he knows, but he simply knows that Liang Qiutao's answer is wrong.

It's a weird feeling, and it's different from intuition.

As a result, the answer is really wrong.

The three of them were a little silent, and after a few seconds, Huan Weibo said, "Is the coordinate system reversed?" ”

As we all know, the coordinate system is divided into x-axis and y-axis, and the botanical garden on each floor is divided into four areas by beige floor tiles, the floor tiles in these areas are very small, and each piece is just enough to hold a flower pot, which is a very obvious coordinate puzzle, so everyone's thinking should be correct...... But why not?

It is possible that the coordinate system is reversed, because everyone calculates the coordinate system according to the angle of entering the door, so the third quadrant is in the area to the left of the entrance, but what if it is the other way around? Maybe it's still sideways?

Since there was no way to confirm the position of the third quadrant, the three of them had to answer three more questions...... But the coordinates of the four areas of the first floor (-6, 4) have been searched, and there is still none.

Now, everyone can only look at each other.

"Why not!" Liang Qiutao unabashedly showed his anxiety, "Why? ”

Cha Mi You and Huan Weibo glanced at each other, each thoughtful.

In addition to the wrong coordinates, there is another possibility: that is, the gardening phoenix is actually lying, and there are more than 8 hints in a set...... But now everyone has turned over 5 more pots, and there are still no new prompts.

"Ah, are we going to look for them one by one?"

Liang Qiutao looked at the staggering number of flower pots in front of him, and looked crazy.

Although Huan Weibo didn't say anything, his toes kept tapping the floor, obviously not as calm as he seemed to be.

Cha Miyou suddenly stared at Huan Weibo's feet, who keenly noticed this gaze, and the action of smashing the floor stopped unnaturally.

"What's wrong?" He asked.

Cha Miyou: "You smash it twice more and let me hear it." ”

Although it sounded like a word of finding fault, but Huan Weibo and Liang Qiutao heard Cha Miyou's seriousness at the same time, Huan Weibo had to smash his feet with tears and laughter, and then, he himself was stunned.

Because the sound is clearer than expected, and there is a slight echo.

I didn't feel it obvious when I didn't pay attention, but now I listened attentively, and soon noticed the anomaly - the bottom was hollow.

Liang Qiutao also quickly realized this.

"In reality, how many floors does the botanical garden of Pinghe City No. 1 Middle School have?"

“…… This is not clear. Huan Weibo shrugged.

If there is a negative layer underground, then the hint can be understood, and the equation that initially indicates the number of layers is not "3-2=1", but "2-3=-1".

"Let's find the path to the negative layer, we've already consumed a lot of time." Cha Miyu said.

The three of them began to look for each other on the first floor, because their perception was limited and they couldn't penetrate the obstacles, so the progress was not fast, and Liang Qiutao couldn't help but stomp on the floor every step he took, for fear of missing some secret door.

However, after a round of inspection, the three of them did not find a secret door or other passages, except for the stairs and equipment room on the first floor, there are floor tiles and potted plants, and they are almost tired of staring at it.

"Maybe we should think differently," Chamiyu said, "maybe the basement isn't here." ”

Liang Qiutao said that he was surprised by this idea: "How do you say this? ”

"Functionally, from a functional point of view," Cha Mi said with his index finger against his chin and his other hand against the elbow of this hand, "The first to third floors of the botanical garden are used by the horticultural specialty classes of each grade, but what is the basement floor used for?" For gardening tools, there is an equipment room on each floor, so there is no need for a basement to store clutter...... But to put it another way, there's a greenhouse area outside, and it's all the type of light transmission, right? ”

Huan Weibo smashed his palm, "Yes, some unique plants just need a cold and damp growth environment, basically belong to the light death, these plants do not need frequent photosynthesis, chloroplasts are scarce in the body, so they will show a unique color, which is obviously a natural good material for gardening...... In other words, the basement should be in the greenhouse area! ”

With this direction, the three of them quickly came to the greenhouse area, but as soon as they came out of the greenhouse area, the three of them were startled, because the outside was full of NPCs-black oppression, all surrounded by the walls of the botanical garden, and the three people who looked straight out of the area were full of fierce light in their eyes.

Liang Qiutao was immediately so frightened that he jumped up and almost hit the ceiling.

I said...... These guys...... How, how could it be ......" she was so nervous that she couldn't speak clearly.

"It seems that the horticultural phoenix is not lying, this is indeed an area where force is absolutely prohibited."

As he spoke, Cha Mi Yu put a freshly rubbed spirit bomb into the backpack space.

"Well, it looks like we've been delayed quite a bit."

A drop of cold sweat hung on the corner of Huan Weibo's forehead, but he was calm: "They can't get in, let's go find the basement first." ”

Liang Qiutao swallowed a little saliva and followed the two to find the basement.

The basement is behind a greenhouse, with a layer of straw at the top, and a layer of fine barbed wire doors underneath the straw, and when the straw is lifted, in addition to the smell of dry grain, there is also the moisture rushing in - there seems to be water in this basement.

Carefully removing the barbed wire door, Cha Miyu took the lead and walked down.
