Looking at Leng Yun's maid outfit, Romanova was dumbfounded. Looking at Romanova's expression, Leng Yun couldn't help but feel a little shy, and he said, "Don't look at me like that!" ”

Romanova sighed and said, "I really don't know why, I feel a little jealous when I see you wearing a maid's costume!" ”

As she spoke, Romanova suddenly stood beside Leng Yun and took out her mobile phone to take a picture. Leng Yun was startled and said, "What are you doing!" ”

Romanova hurriedly put her phone in the valley between her two plump peaks and said: "If you want to snatch it, then come!" ”

A big bead of sweat appeared on Leng Yun's head, and Romanova said with a smile: "This photo can be used as a permanent treasure, if it is auctioned, the price may not be inferior to any expensive antiques!" ”

At this time, Leng Yun's mobile phone rang, Leng Yun took out his mobile phone, and saw that Leng Qianqian's cartoon image was smiling evilly on the mobile phone screen. Although, he saw the selfie of him in a maid costume just now.

I saw a line of text near Leng Qianqian's cheek: "Dad, my mother died when I was born, and when I think of my mother in the future, you will put on women's clothes, okay?" I think you look better in women's clothes than Aunt Linxiu and Aunt Hu Fei'er. ”

"If you praise me like this, I won't be happy at all!" Leng Yun complained silently in his heart, and then the change in the interface of the mobile phone made Leng Yun's heartbeat stop.

It turned out that Leng Yun's mobile phone automatically sent this picture in groups, and the recipients were Lin Xiu, Hu Fei'er, Gaia, Bai Qiumeng, and Lila.

Leng Yun kept pressing the cancel button, of course it had no effect, and a few seconds later, Lin Xiu, Hu Fei'er, Gaia, Bai Qiumeng, and Lila all received this picture message.

"What the hell is this?"

"Hahahahaha......haha

"Has God's power been upgraded again? You can become a girl! ”

"Who's the other blonde girl? Why are you so close to Leng Yun? ”

"Uh......h I'm so unwilling, why do I think Leng Yun in a maid costume is even cuter than me! ”

Several girls expressed their own feelings, although Leng Yun didn't hear these feelings, but he felt that the whole person was not good, and he felt that his whole person was collapsing.

"Are you angry?" Romanova's somewhat panicked voice suddenly came, Leng Yun hurriedly cheered up, and said with a smile: "No, let's go investigate!" ”

Romanova looked at Leng Yun and couldn't help but laugh again, Leng Yun sighed helplessly.

The two of them walked out of the room together, Romanova's female companion glanced at Leng Yun in surprise, and was about to speak, Leng Yun said: "I know what you have to say, but please take care of my emotions and don't say any more......"

Romanova's friend covered his mouth and laughed for a while, and said, "Okay, if you want to visit, hurry up and visit, and then leave early, don't cause any trouble." ”

So, Leng Yun and Romanova began to explore in the museum. Of course, the first and second floors did not find any clues, and Leng Yun said to Romanova: "It seems that we have to go up to the third floor to have a look." ”

Romanova nodded, and Leng Yun said, "In this way, you help me release the wind on the second floor, and I'll go by myself." ”

Romanova knew that Leng Yun's skills were much better than herself, and if she followed, she would be held back, so she said: "That's fine, I'm here waiting for you to come back, you have to be careful." ”

Leng Yun nodded, carefully walked up the stairs to the third floor, he put on invisible headphones, and kept moving forward according to Leng Qianqian's guidance, bypassing the cameras and guards.

And for the sake of insurance, Leng Qianqian still manipulated the monitoring device, so that the security equipment could not track Leng Yun's figure.

Leng Yun explored the entire room on the third floor, and at first he didn't find any problems, but when he checked in the study on the third floor for the second time, he found some inconsistencies.

There was a set of sofas by the window in the study, and I didn't look carefully for the first time, but this time Leng Yun found that the color of one of the sofas in this set of sofas was slightly different from the color of other positions, and I couldn't see it at all if I didn't look carefully.

Leng Yun came to the sofa to take a closer look, but did not find any clues, of course Leng Yun did not dare to disassemble the sofa to investigate, he asked Leng Qianqian to scan the sofa, there should be nothing hidden inside.

Leng Yun was a little frustrated, and sat on the sofa, where he was sitting in a position of different colors, and when he sat down and looked forward, he found that in front of this position was a writing desk, and in addition to the desk lamp, there were several books and a mirror.

"How can there be a mirror on a desk?" Leng Yun immediately felt that something was wrong, so he walked to the desk and found that the direction of the mirror was a little crooked. So, Leng Yun adjusted the orientation of the mirror, so that the mirror was directly facing the sofa with a somewhat different color. However, the entire room remained unchanged.

Leng Yun thought for a while, returned to the position of the sofa, and looked at the mirror, and at this moment, the bookshelf behind the sofa was reflected in the mirror.

Leng Yun looked back at the bookshelf and found that in addition to some books, there were also some porcelain on the shelf. After Leng Yun carefully observed the bookshelf, he found that the bookshelves were divided into two parts equally, and although the books placed in the two parts were different, the size and height of the books were almost the same, which seemed to be deliberately discharged in this way.

Leng Yun found that the only discord on the bookshelves on both sides was the porcelain placed on both sides of the bookshelf, although the porcelain was a vase and the style was the same, but one was yellow and the other was green. The style of the two porcelain vases is exactly the same, but the colors are clearly different, which obviously has a certain meaning.

Leng Yun tried to turn the two vases, but nothing happened, apparently there was no mechanism underneath them.

Leng Yun really couldn't think of any clues, so he took out his mobile phone and told Leng Qianqian the clues he found. Leng Qianqian immediately began to conduct an all-round Internet search, and said after less than 3 minutes: "I think it may have something to do with the wavelength of light." ”

"Wavelength?" Leng Yun asked, "What does that mean?" ”

"Every color of light has a fixed wavelength, with yellow light having a wavelength between 570 and 585 nanometers, and green light having a wavelength between 492 and 577. ”

Leng Yun listened to these two sets of numbers and asked, "Is there any point in this?" ”

Leng Qianqian said: "The number may represent a certain meaning, but what does it mean, you still need a codebook." ”

"Codebook?" Leng Yun thought about it, and he suddenly found that there was this book directly under the two porcelain, these two books were very suspicious, because both books were "Encyclopedia Britannica", and they were the same volume, except that one volume was in English and the other was in French.

Leng Yun smiled and said to Leng Qianqian: "The codebook has been found!" ”
