Mu Sichen went up to the second floor with the gift box.

He knew the layout of Gu Yunnian's house, and when he went upstairs, he walked directly outside the study and knocked on the door.

Gu Yunnian thought that it was Yunshui Ballad who came up, so he called in without raising his head.

It wasn't until footsteps sounded that she realized something was wrong.

Compared with the Yunshui ballad, the footsteps of the people who came were much softer.

She looked up and saw Mu Sichen in surprise, "Mu Sichen, aren't you leaving?" How did you get back? ”

"I haven't given my birthday gift yet, how can I go!" Mu Sichen directly put the gift box in his hand into Gu Yunnian's arms, and looked at her with a smile, "Open it and try it." ”

Gu Yunnian looked at the rectangular gift box in front of him, which was half a meter long and a foot wide, and it was a little heavy on his lap.

She reached out and pulled open the royal blue bow brocade on the box, which spread out and lifted the lid.

What catches the eye is the black brocade that is flush with the box surface, with a concave piece in the center, and a flat inlay with the surrounding brocade with a screen on the top and a keyboard below, like a mobile phone.

"Is this a phone?" Gu Yunnian's eyes were puzzled.

Is there such a phone with a large screen now? Not long ago, what she saw in the mobile phone city was all small screens.

Mu Sichen only nodded, and said with a smile, "The phone has been charged, you take it out and try it!" ”

"Hmm!" Gu Yun replied, took out his mobile phone, turned it around in his hand first, and looked at it.

It was a white phablet, the size of her palm, the thickness of her little finger, with a screen on top and a keyboard on the top.

She pressed a button at random, and the screen lit up, and she was surprised to see that the screen turned out to be colorful.

Is there a color screen phone now?

Gu Yunnian was in a trance thinking about the various mobile phones in the mobile phone city, which were exquisite and good-looking, but most of the screens were black and white, and very few were blue-ray.

Mu Sichen didn't see the doubt in her eyes, and began to explain to her the hidden functions of the mobile phone.

He pointed to the left side of the phone with white bumps that were barely visible without looking closely.

"The top button is to control the built-in lens. Double-tap quickly and the camera will pop up. As he spoke, he demonstrated to Gu Yunnian.

Gu Yunnian looked at the right side of the top of the phone, and a square lens that was only half a centimeter thick and one centimeter wide popped up.

Mu Sichen pressed the button to turn on the lens again, and the screen showed the picture under the lens.

She was surprised to see that the screen was a little smaller, but it was unusually clear, not at all as blurry as the one she had seen on the mobile phones of her colleagues she worked with.

Gu Yunnian lowered her head, and Mu Sichen didn't show the surprise in her eyes.

Then he said: "Press once to take a photo, press twice to record a video, and press and hold for three seconds to turn off." When you put the lens away, just press it in. ”

He handed the phone to Gu Yunnian and asked her to push the camera forward with a slight force as he said. Looking at the phone again, there is only a subtle gap in the position of the camera.

Then, Mu Sichen told Gu Yunnian about the functions of the remaining buttons.

One recording, one locating, and one distress button.

When the final distress button is activated, Mu Sichen's mobile phone will call the police and automatically locate her location.

Compared with the last two functions, other functions such as listening to music, surfing the Internet, and playing videos are nothing.

There is also a fingerprint recognition.
