"That's right, this is precisely one of the keys to solving this puzzle, the reason why Murong Feng deliberately used different brushstrokes and fonts to cover up that these calligraphy and paintings were made by the same person, his only purpose is to make us think that these calligraphy and paintings are his collection for many years, or someone else's pen and ink, and in this way, we will not be able to guess the important key." I said.

"The key to the matter? What's the key? Zhao Yuyu asked.

"The key to this is that all landscape verses describe the same place." I looked around in a low tone.

"Cheng Yin, do you mean to say that all these landscape paintings, poems, and songs are all depicting the same thing? But this ...... How is this possible? Although these paintings are somewhat similar, it can't be said with such certainty that they are the same mountain, right? Zhao Yuyu said.

"That's right, Cheng Yin. If you look at this painting, there is a huge waterfall on it, and the other calligraphy and paintings don't have it on it. In this way, it seems that these calligraphy and paintings should depict different mountain peaks. Cui Li asked puzzled.

Just as I was about to answer this question, Xia Cheng, who was still pondering, suddenly stood up and walked in front of us. He took out a piece of paper and said to Cui Li: "Cui Li, what do you see on this piece of paper?" ”

Cui Li carefully looked at the piece of paper in Xia Cheng's hand and replied, "Xia Cheng, there's nothing on this paper?" ”

"Are you really sure there's nothing?" Xia Cheng confirmed again.

Cui Li really felt that this question was too simple, pointed to the blank paper and said confidently: "That's right, there's nothing on it, I'm pretty sure." ”

At this moment, Xia Cheng flipped the paper in his hand and put it in front of Cui Li, not expecting that what was drawn on the other side of the paper was the topographic map of the maze before.

Xia Cheng asked again, "Do you still think there's nothing on this piece of paper now?" ”

"Xia Cheng, this can't be counted. You just showed me the front side of the paper, how do I know you also drew a topographic map of the maze on the back side? Cui Li said unconvinced.

"I see." Zhao Yuyu on the side suddenly realized.

"Cui Li, Xia Cheng didn't deliberately trick you. Have you forgotten the hint that Murong Feng gave us earlier? I asked.

"Hint? Of course, don't you mean that only someone who is good at math can solve this puzzle? I'm very good at math, Cheng Yin, you know, my best in school is science! Cui Li replied confidently.

"Are you sure? I don't know who always likes to hold some poems, prose, and literary works, pretending to be very literary. "I made fun of Cui Li.

"Cheng Yin, when is it, what are you talking about?" Cui Li muttered quietly.

Xia Cheng walked to the wall of the hall, took down two different landscape paintings from them, and then returned to Cui Li's side and said, "Cui Li, you said before that the scenery in these paintings is like this waterfall that does not appear in other paintings, but in fact, the reason is the same as the paper just now. ”

Xia Cheng stacked the reverse sides of the two paintings together and continued: "Look, what can you see from this side? ”

"The bamboo pavilion in the mountains, and some pine trees or something, right?" Cui Li looked at the painting in front of him and said.

Xia Cheng hurriedly turned the landscape painting on the back and said, "What can you see now?" ”

"The waterfall? But aren't these two paintings? Cui Li still looked dazed.

"Cui Li, Murong Feng said before that only by observing from different angles can new clues be discovered. If you put yourself in their shoes, when you stand on one side of the mountain, you will never know what the scenery is on the other side of the mountain. It's like what is written in this ancient poem. Xia Cheng walked to the front of a pair of verses: "Looking horizontally, the side of the forest is a peak, and the distance and height are different. I don't know the true face of Lushan, only because I am in this mountain. ”

Through Xia Cheng's explanation, Cui Li suddenly realized, "So that's the case!" Hey, Xia Cheng, didn't you understand if you said I wouldn't have understood? ”

In fact, the sentence that Murong Feng added before can only be solved if the math is good, and it does not refer to the operation of numbers. Rather, it is the most important category in mathematics - solid geometry. The so-called solid geometry is to present a three-dimensional model in the mind, and the situation is the same now, to combine these paintings in the mind and present a real mountain, the answer lies in it.

Xia Cheng presented us with the drawings that he had drawn there before, and it turned out that he had already discovered this clue, combined these different landscape paintings on the drawings, and had already drawn a three-dimensional figure of this mountain peak.

"Xia Cheng, I can't see it, not only do you have a good brain, but you also draw well!" Cui Li's words of praise made people a little speechless.

Everyone looked at the drawings drawn by Xia Cheng, and it didn't take long for new questions to arise. Although Xia Cheng drew the whole picture of the mountain peaks on paper, we didn't find any useful clues in it. In other words, after a long day's work, nothing new was discovered.

Cui Li walked up to Murong Feng angrily and said loudly: "Okay, you Murong Feng!" You designed this labyrinth, right? Now that we have solved the mystery of these calligraphy and paintings on the wall, Xia Cheng has even drawn the three-dimensional figures of the mountain peaks, why is it that nothing has changed? Don't tell us, we're wrong again. ”

Murong Feng didn't answer Cui Li's question immediately, but smiled mysteriously, and then clapped his hands, "Very good, very good, it seems that you still have some brains, but you ......"

Murong Feng glanced at Cui Li beside him, revealing a look of disdain, "But didn't you hear my prompts clearly?" Or do you only care about the last word? There are three parts to this puzzle, and you've only solved most of them. Do you want me to give you a dance to celebrate? ”

It seems that the first mystery of this maze has not yet been fully solved, but there are two other mysteries waiting to be found.

"Come and see!" Lin Yun suddenly shouted, "Come and see, I seem to have found some important clues." ”

We walked to the table, and although I didn't know what Lin Yun had found, I felt that hope was ahead.
