The piano is on Su Yi and Qi Zihan's side.

It's an old member, seeing a piano placed here, Qi Zihan intuitively felt that she had something to do with the password, so she walked to the piano and put her hand on it and then played it.

However, there are problems with these two cases.

Instead of a melodious and mellow sound, the piano came with a shrill scream, like a human voice.

Hearing this sudden scream, except for Su Yi who frowned slightly, the others couldn't help but scream and were startled.

Although Qi Zihan is an old member, she has also experienced several frightens from the program team, but she is a girl after all, and when she heard the sudden piercing scream, especially from the piano under her hand, she exploded in an instant.

Frightened, he immediately stayed away from the piano, and then quickly hid behind Su Yi, tugging on her clothes tightly, leaning his head on her shoulder and not daring to raise his head and open his eyes.

Originally, there was still a strange relationship, because this Pa made the two of them a little closer.

The sound of the piano can be heard not only by Su Yi and them, but also by Mu Nan next door.

Mu Nan, who had promised to protect people in a majestic manner a second, had already hid behind Ji Shaochu in fright at this moment.

The sudden piercing sound of the piano startled them, except for Su Yi who stood still and held on tightly to Qi Zihan, who didn't dare to move, Mu Nan and the others were already hiding in the corner in fear.

After the sound disappeared, after a long time to make sure that there was no more, Mu Nan and the others came out of the corner, and then walked to the glass and looked at Su Yi and Qi Zihan.

"What just happened? How could there be a scream all of a sudden, and it didn't sound particularly like it. Xu Huan, another member assigned to Mu Nan, couldn't help but ask Su Yi and them.

Although there was a glass and a door between the two teams, the sound could still be heard by each other.

Qi Zihan should also be relieved, slowly raised his head from behind Su Yi, and then said: "Just now I just saw that there was a piano, and I wanted to go over to see what clues there were, but it turned out to be like this." "Worry-free

They are all old members, and when I heard it, I knew that the piano should be a very important clue, and it must be related to the music scores scattered all over the ground.

"Don't touch the piano yet, let's find clues first, our door will be opened." Ji Shaochu commanded.

Then everyone went to look for clues according to Ji Shaochu's instructions.

Su Yi has Moss, in fact, she can easily know the password and know how to open the door.

But Su Yi didn't do that, she didn't ask Moss to help her.

Su Yi first walked to the door and looked at the lock, and found that it was not an electronic lock on her side, but a combination lock.

It's a five-digit password, and the color of each digit is different.

Seeing this lock, Su Yi walked around their classroom and found that there were no clues related to color.

Thinking that the clues in the room might be generic, Su Yi stood in front of the glass and looked through the glass at the classroom where Mu Nan and they were.

Then, Su Yi used her extremely good eyesight to find a green thing on a tabletop.

Green, the color on the combination lock.

So Su Yi knocked on the glass a few times.

The voice reached Munan's ears.

Seeing that it was Su Yi who knocked it, Mu Nan walked to the glass and asked, "What's wrong, Sister Su Su?" ”
