The three men walked along the edge of the staircase, leaning over, carefully observing each of the adjacent tiles.

Mo Chen shook his hand and flew out again, and the lightning struck another floor tile with a clanging sound.

The lightning flashed and lost its brilliance, and since it has not been seen since, Mo Chen felt that the "ding" just now seemed to be a little different from the previous one.

At this time, Dai Min suddenly screamed, Zheng Yi approached her and asked what she had found, Dai Min pointed to the floor tile that Mo Chen had just hit.

Dai Min said, "I just saw some pattern! Speaking of this, she was a little unsure, and reached out to scratch the hair behind her ear, her eyes a little dazed.

Zheng Yi raised his eyebrows, kept his eyes open, and stared at the floor tile.

The walls and floors of the second hall are all dull crystals, so that the light is not particularly good.

Seeing this, Mo Chen shook his hand and another bolt of lightning flew out and hit the floor tile just now.

With a bang, the ground thorn appeared violently, and Zheng Yi shouted, "I'm C!" Tell me! Scared Lao Tzu. ”

Mo Chen smiled wryly, shrugged his shoulders and said, "Aren't I warm-hearted!" Help you shine the light. ”

"Fuck your uncle!" Zheng Yi glanced at Mo Chen, because of the trigger of the ground thorn, the patterns on the floor tiles could not be distinguished at all.

Mo Chen helped, knowing that he was at a loss, he coughed dryly and said, "In this way, I'll fly the lightning a little higher later, and you take advantage of the light to hurry up and tell what the pattern is." ”

Zheng Yi put his hands behind his back and made an OK gesture to Mo Chen, and Mo Chen gave a signal and said, "It's coming!" Then another bolt of lightning flew out.

Lightning flew in mid-air, illuminating several of the floor tiles below, and the surface of the tiles was indeed patterned. A few clear patterns of illuminated floor tiles look like a corner of a mountain, and a bit like land.

Seeing this, Mo Chen continued to throw a few bolts of lightning, if there was no other way, Mo Chen didn't want to do this. Because every time, it is difficult to see the pattern of the brick clearly, and then it will trigger the ground thorn, which is not a waste of time.

In order to save time, Mo Chen simply separated each lightning bolt that was thrown out at some distance, and used some of the patterns he saw each time to connect them with his brain.

Zheng Yi and Dai Min's attention was mainly focused on the patterns of the floor tiles, and Mo Chen didn't have much time to distinguish the patterns because he needed to control lightning.

But because of this, Mo Chen had the energy to scatter on the sound, and at the beginning, Mo Chen just unintentionally heard the sound of lightning falling to the ground. Slowly, he found that it seemed that after each floor tile was "tapped", the sound that bounced back was different.

Mo Chen suddenly thought that maybe the order in which each floor tile was knocked was actually related to the sound.

At this time, Dai Min suddenly shouted, "It's a castle!" Instead, she confirmed the matter with Zheng Yi and said, "You also saw it, right?!" It seems to be a castle...... A castle floating in the air. ”

Zheng Yi touched Dai Min's forehead dotingly and said, "Hmm! It's the city in the sky. ”

"That's right! Castle in the sky. Dai Min exclaimed excitedly, and continued, "The patterns on the floor tiles will not appear for no reason, this must be a clue." ”

"Mo Chen." Dai Min called Mo Chen and said, "You help me take care of this, it's not good, the staircase to Sky City is the right route to the opposite side." ”

Mo Chen posed to throw lightning, but he didn't make a move, he said, "No, I don't think it's that simple." Haven't you noticed that the sound of the bounce of the tiles is different? ”

Dai Min thought about it, shook his head and said, "This ...... I didn't notice. ”

Zheng Yi smiled and said to Dai Min, "Lao Mo has absolute pitch, we don't have this skill, ignore him." ”

Mo Chen's face was black, and he secretly blamed Zheng Yi in his heart, when was it, he didn't forget to be greasy and crooked here with Dai Min, piggybacking on him.

Mo Chen said, "I don't have absolute pitch, I don't study music, and I don't know music. After a pause, Mo Chen said solemnly, "I'm serious, don't you really feel it?" The sound that bounces off each tile is really different. ”

Zheng Yi raised his hand and motioned to the floor tiles, Mo Chen's meeting, and two lightning bolts hit the place in succession, and Dai Min asked him to help illuminate the place just now. Two lightning bolts struck the two tiles and clanked twice, and this time, all three listened with their ears sideways.

After the sound, the ground thorn was triggered again, and a trace of disappointment flashed on Dai Min's face, because the two floor tiles that had just been hit by Mo Chen were the beginning of the "password" she thought it was.

If the floor thorn is not triggered after these two sounds, then it means that her thinking is correct, otherwise, they don't need to worry about whether the step pattern of the floor tile is the two "passwords" at the beginning.

Zheng Yi's eyes rolled, and he stared at the floor tiles carefully, as if he could see the sound by staring so hard.

"How?" Mo Chen asked.

Zheng Yi plucked his ears and said, "When you said that, I really feel that the voice is a little different." ”

"Can you be serious!" Mo Chen said angrily.

Zheng Yi said: "No way! Brother Yi is old, and his ears are not as easy to use as you young people. ”

“C！” Mo Chen waved his hand, not wanting to entangle with it.

Dai Min said, "I also think that the two voices are not very different, but if the sound is the password, where do you prompt?" Dai Min glanced around and said, "I didn't see any similar notes!" ”

"Maybe the pattern is the cue?" Mo Chen said.

Dai Min looked at Mo Chen in surprise, in fact, Mo Chen was not sure, but he had a feeling in his heart. He couldn't help but think that the pattern on the ground was a bright hint.

So, Mo Chen said, "The song of the city in the sky." ”

After a pause, Mo Chen explained, "On the pronunciation of the floor tiles, knock out the song of Sky City, in fact, it should be said that we follow the simple score of Sky City to step on the corresponding floor tiles, which is correct and can reach the opposite side safely." ”

Zheng Yi spread out his palms with a sigh, and said, "Then forget it!" Don't talk about the score of Sky City, even if you draw a note for me, I don't recognize what the hell it is. ”

Mo Chen lowered his head, he had just thought about this, in fact, just now he tried to listen to the sound of the floor tiles bouncing back, trying to distinguish the sounds of do (many), re (come), mi (m), fa (hair), sol (so), la (pull), si (west).

Although, with Mo Chen's unremitting efforts, he probably heard a few notes, but he had to use the melody in his mind to "silently write" the score, which was difficult for him, a music layman, to climb to the sky.

Mo Chen suddenly regretted why he didn't cherish the time in music class when he was in school. At that time, music lessons were only used for entertainment, like cucumber slapping in a high-class banquet, just for appetizers.
