Coco spread her hands: "Who else can there be?

"Why is he so fast!" As soon as Xiaoxi finished speaking, the door was opened by the boss, and then Shen Yan and Du Sen walked in, and the boss locked the door again.

"HELLO!" Dusen was the first to walk in and greet them.

Xiaoxi responded politely: "HELLO!" Coco continued to look for clues on the sidelines, ignoring them.

Dusen pointed to Xiaoxi and Coco: "Who is your girlfriend between the two of them?"

Shen Yan didn't answer, he directly skipped Du Sen and walked towards the stream, holding her in his arms.

"Huh!" Du Sen suffered another 10,000 critical hits, and his hands were trembling angrily: "You guys!"

"Don't hug me, why don't you come and help me find clues. Coco interrupted the two of them, Coco, who is a single dog, does not allow others to show affection in front of her, and is extremely unhappy, not because he was used for dog food, but because he doesn't know how, he doesn't have a good impression of this Shen Yan, but he is quite wary of him.

"Okay!" Dusen took the lead and walked to Coco's side, feeling very proud: "I can't cure you, someone will cure you!"

Xiaoxi pushed Shen Yan away, took his hand and walked to Coco's side, explaining as he spoke: "Our escape room happened during the Republic of China, the Eighth Route Army hid a document here, we need to find it, and we have found a key and a Morse code." ”

"This room is so big, it's going to be easy to find!" Dusen looked confident and began to rummage.

This room is about 60 square meters, and the furnishings inside are the same as in the Republic of China, and the things are very simple, with 3 flat tables and 3 chairs, which are placed vertically one by one.

There was a desk, and the desk was placed backwards, as if there were students below and a lectern above.

Next to the desk is a bookcase full of books.

In the corner opposite the bookcase there was a clothes pole on which two pieces of clothing were hung.

On top of that, there's a worn-out lockbox, and that's pretty much it.

The key they found was found in the pocket of a piece of clothing, which opened the desk cabinet, and when opened, there were only a few letters and a Morse code analysis.

"Don't move, as long as one step is messed up, every next step will definitely be messed up. A basin of cold water from Coco's hand extinguished Dusen's mysterious self-confidence.

Shen Yan took the letters and looked at them carefully, they were ordinary letters.

Dear Yu, hello, do you remember when we watched the sunset together? I wore a blue dress, you gave me a white bag, and you gave me a khaki book, do you remember? Thinking about how beautiful the days were, it's a pity that the two of us can't see each other again, I'm very sorry, I miss you very much, and I look forward to your reply.

Signed: Fang.

The other letter was addressed to her.

Dear Fang, of course I remember those good days, but I remember that you did not wear a blue dress, but gray, and that white bag was given to you by me, but that book was given to you by Madame, and it was not khaki, but green, have you forgotten?

What a wonderful time it was, and I knew that the two of us would never see each other again, but I still hope that one day, we can meet again.

Signed: Yu.

The rest of the letter was written a little more formally.

We have been discovered and have been forced to retreat, and I would like to warn you that there is a spy among you who is trying to decipher your secret words, and I hope you will pay attention to it and must not let him succeed.

The letter was not signed.

"That's all, nothing else?"

Xiaoxi shook her head: "Coco and I have been stuck at this step for a long time, and we don't know how to crack it." ”

Dusen was still rummaging around for clues, he walked over to the hanger, felt the pockets of two clothes, and found nothing.

He carefully touched his clothes, and suddenly felt that he had touched something, and he immediately beckoned, "Come here, come quickly, there seems to be a sandwich in this dress." ”

Shen Yan immediately walked over and touched his clothes, there seemed to be a piece of paper inside, "This is not a mezzanine, it's just a relatively hidden pocket." Shen Yan took out the paper.

The three of them all came over in unison, only to see a few numbers scattered on this piece of paper, one, two, three, four, five, six, and the rows were messy.

Dusen took the paper first and shone it under the light to see if there were any clues.

Flipping through the pages, "This piece of paper doesn't seem to have any other clues except for these numbers!"

I really couldn't see anything, so Du Sen simply didn't care, put down the paper, and continued to look for clues.

Coco looked at the paper, and then looked at the three letters, and Coco picked up the paper, and took one of the letters, and the two pieces of paper overlapped, and magically found that the numbers overlapped with the colors, white, blue, gray, khaki, green, and white, and the other number was on the sunset.

"This sunset should be yellow!" Xiaoxi and Shen Yan looked around, and there seemed to be no other color except for the books on the shelves.

Xiaoxi just wanted to get the book, but was caught by Shen Yan, "Don't move, maybe the order of the book is the password of the lockbox!"

"Oh!" the brook took her hand back.

Coco walked over to the side of the box and checked the combination lock, "It's only 4 numbers!"

Xiaoxi pointed to the bookshelf: "This bookshelf only has 4 rows!"

The first row has green and blue, the second row has white and gray, the third row has khaki and yellow, and the fourth row has white and yellow.

Each row has two colors of letters, which are sandwiched in the middle or placed next to the books of other colors.

"The first row should correspond to the first password number. Shen Yan touched his chin, "Two colors, it should be a duplicate color, not counted, in this case, it is just 4 digits." ”

Xiaoxi picked up the letter, "White, yellow, only these two repeated!"

The letter said that blue and khaki were misremembered, and excluding these four colors, there were just four colors left. ”

Coco walked over to the bookshelf, pointed to the second and fourth rows of the bookshelf and said, "If I'm not mistaken, the second row should be gray and the fourth row should be yellow." So it just so happens that each row has a color. ”

Shen Yan raised his hand, "I also agree with Coco's statement!" He walked up to the lockbox, "You report the numbers to me, I'll try!"

"It doesn't look like you're stupid!" Coco glanced at him and nodded silently, "If you match Xiaoxi, it's okay!"

Du Sen is still looking for clues on the side, silently looking!

Xiaoxi pointed to the bookshelf: "The first row, green, is the fourth book." The second row, gray, is the first book. The third row, yellow, is the 6th book. The 4th row, white, is the 3rd book. ”

Xiaoxi reported the number, and Shen Yan filled in the password according to her number!

All four were filled in: "No, it can't be opened, there must be something wrong with us." Before they could react, the 'click' was suddenly opened by Shen Yan again.

"It's on!"

"Didn't you say the password was wrong?" Coco stepped forward to look, and inside was a box.

"It's wrong in the order we just had, the password is wrong, but I remembered the last letter, and it said there were spies, so maybe the numbers were out of order, and I opened the code according to their size on that piece of paper, and it was opened. ”

Shen Yan picked up the box inside, this box is very exquisite, a little old, there is an old copper lock on the box, there is only so much.

He helplessly held his forehead: "There is a small box in the big box, and I am speechless." ”

Xiaoxi curiously took the small box from his hand! carefully examined: "This box looks so good!" She flicked the lock, and the lock was so dead that it couldn't be opened.

"Isn't there anything else in there?"

Shen Yan pursed his lips and shook his head: "No!"

At this time, Du Sen, who was silently looking for something on the side, spoke: "I just found a key, you can see if it's this one!"

Dusen put the key on the desk, and Coco picked it up, "Where did you find it?"

"Inside that tie pole, I found a gap in the tie pole, I tried to see if I could open it, and I really opened it, and there was this key hidden inside!"

Shen Yan put his hand on Du Sen's shoulder and glanced at him with disdain: "Never hide something under his nose, nothing can escape his thief hands!"

Du Sen slapped his hand open and patted his shoulder disdainfully: "It's hard to admit that others are excellent!

Coco ignored them and handed the key to the stream.

With a 'click', the box was opened. Du Sen and Shen Yan were attracted by this voice, and there was another letter inside.

Coco took out the letter and placed it under the lamp.

Congratulations, you've taken a big step, you'll have to work harder to find the key to get out of this room, and I'll give you a little hint that there is a small mechanism in the room, and the way to open it is in those three letters!

"One ring after another, one after another! Wonderful!" Du Sen applauded weakly beside him, not from the heart, but it was too boring and boring, I thought it was over, but it turned out to be there!

The three of them ignored him, and as soon as the three of them saw the mechanism, they thought of the cabinet under the bookcase, there was obviously a gap, but it just couldn't be opened, and there was no handle!

Shen Yan knocked, "It's hollow inside!"

"How do you open this, there are no keyholes, and there are no other buttons!" Xiaoxi broke the cabinet, but it didn't affect at all!

"Didn't you say that? the clues are in those three letters!" Coco took the three letters, and had no clue!

I saw Shen Yanzai take down all the books of those colors, take out all the books in the fourth row, put them on the ground, and then put the books in one by one, and then gently moved the fourth book, that is, the white book, and then only listened to the 'bang', and the cabinet was opened.

Xiaoxi looked at the bookcase that opened the door with an incredible look, and said in surprise: "You are too powerful!"

Coco was also surprised, she squatted in front of the bookcase and opened the cabinet door completely: "Shen Yan, how did you do this?"

Shen Yan spread his hands: "Isn't it a reminder that the clues are in the letter?" I tried to sort them according to the color of the book, the password has 4 digits, and there are 4 letters in total, so I moved the 4th book, and it opened!"

At this time, Dusen spoke, holding the Morse code: "Then what's the use of this Morse code!"

Coco sighed, pointed to the open bookcase and said helplessly: "It's not over yet, there's still a safe in the cabinet!"
