After looking around, Li You couldn't find where the person who spoke was hiding, and it wasn't until Xiaolan stretched out her finger and pointed to a speaker hanging on the roof of the shed that she understood what was going on.

Su Marie, a radical old woman in the second world. Li You seemed to be able to remember the way she looked in a white coat, her high cheekbones, her face full of wrinkles, and her weird way of speaking.

Thinking of this, he only hoped that this woman would not be like the Su Marie in his impression, arrogant and domineering.

"Teacher, I'll bring a friend to see you." Xiaolan said to the air when Li You was stunned. It took a long time to get a response from the speaker.

"Hey, you can come here, and you won't get me anything." After Su Marie's somewhat distorted voice disappeared, the airtight door five meters away slowly opened.

Xiaolan subconsciously took Li You's hand and walked towards the door, and as soon as she entered, Li You felt an invisible sense of oppression. From the ceiling to the floor, there are tangled fiber optic cables and wires everywhere. The dim light is also blocked by most of it, and it takes a while to get used to the environment in the house.

After carefully bypassing these wires, there were tightly placed cabinets in a circle, and Li You hurriedly asked Xiaolan what these were for.

"These are all server groups, and after the cyber war, the data in our servers is basically lost, and the only backup is here."

Li You looked at these cabinets, suddenly thought of something, and opened his mouth to ask: "When I investigated Huang Baiqian with Sister Wu in the team before, I found that there was no photo of him in it, is it because of the Internet war?" ”

"Yes, if we finish dealing with our affairs in a while, I will help you see if you can find Huang Baiqian's information." After Xiaolan finished speaking, she hurriedly walked inside, and finally stopped in front of a small room inside.

This room is completely independent like an enlarged version of the box, and through Li You's preliminary judgment, he feels that this house should be some kind of insulating material.

Just as he was about to take a closer look, around the room, a light suddenly lit up, and Su Marie's face immediately appeared on the four walls of the room, and Li You realized that the walls were all assembled from screens.

These four faces are not real human faces, but three-dimensional images drawn with some kind of software, which look weird because there are no stickers.

"Xiaolan, why have you lost weight again, how many times have I told you, if not, don't do that job, come here to help me." The faces on the walls were talking to themselves.

Xiaolan smiled bitterly, cleared her throat and said, "Teacher, let's talk about the main point, I have a request for something for this sudden visit." ”

"Tell me first, is this for yourself, or for the little white face next to you?"

When Li You heard the word little white face, he suddenly felt a little aggrieved, since he was a child, he couldn't say that he was a good student, but no one had ever described himself like this.

But when Xiaolan heard the teacher's words, she hesitated for a while, and then said with a smile: "Eh, teacher, don't keep making fun of me, I really have something important to look for you this time." ”

"Hehehe, you still don't know how to lie", and with that, the face on the wall disappeared, and the huge room fell into darkness again. Then, from the sound of mechanical gears in the corner, a door opened from the wall behind the small room.

A man in an electric wheelchair is slowly walking around in front of the two. Li You looked at this face, and said in his heart that it was not as pleasing to the eyes as Su Marie in his memory.

a head full of silver and white hair, neatly lying upside down on the head; Due to age, the skin on the face has become so loose that it is not good, like melting ice cream, hanging on both sides; The whole face, only the pair of eyes can still be seen, and the blue is like the sea.

When Xiaolan saw Su Marie, her face was sour, and she hurriedly walked in front of her, squatted down and stroked her old hand and said, "Teacher, what's wrong with your leg?" ”

"I'm old and too lazy to move around. Let's not delay our work, let's talk about something. After Su Marie finished speaking, she turned her eyes to Li You.

Seeing her look at him like this, Li You felt a little awkward and smiled awkwardly. Xiaolan wiped the tears from the corners of her eyes, sniffed her nose and said, "Teacher, I came here today to ask if you can help us get high-density radiation protection materials?" ”

"Then only osmium-99 will be used, but you should know the price of this material, right?"

Xiaolan pushed Su Marie to the dining table, poured a cup of coffee for the teacher, and then said: "The money is not bad, we don't use much, we just want to get it quickly." ”

Taking a sip of coffee, Su Marie looked at Li You and said, "Then you are quite lucky, I really know who has it." Then, she spun her wheelchair with her coffee and said to the little house, "But you have to tell me what you want to do with it?" ”

"I have a device, Xiaolan said there is radiation, and I want to make a protective cover." As soon as Li You finished speaking, Su Marie hurriedly turned around and asked Li You what kind of instrument he was.

The two looked at each other, and after a while, Li You nodded, and Xiaolan said the role of the instrument.

", can you guys get creative? If you want to use time travel to deceive me, you have to wait until I have Alzheimer's to use it! ”

Seeing that she didn't believe herself, Xiaolan hurriedly walked up to her and said nervously, "Teacher, I have never lied to you, this is true." Li You really crossed over from another world. ”

The three of them in the room were arguing, and suddenly all the lights went out, and then the red siren lights flashed. Li You looked at Xiaolan and asked what was going on.

Su Marie looked around in a panic, then quickly got up from her wheelchair and said to the two, "You come with me." ”

The three of them walked around to the back of the small room, and Sumarie reached out and pulled down a bundle of wires that hung on the wall, and a button appeared on the wall. When pressed, a door opens in the wall, and the space inside is about enough for two people.

"Get in!"

"Teacher, what's wrong?"

Su Marie pushed Xiaolan in, then glanced at Li You and said, "You guys hide inside, if I get caught, you go into the control room, and you will find what you're looking for!" ”

After Li You also stood in, Xiaolan looked at Su Marie with red eyes, and wanted to open her mouth to speak, but she covered her mouth.

"Don't worry about me." With that, Sumarie reached out and closed the door.

Inside the wall, Li You and Xiaolan stood face to face, although now is not the time to be cranky, but the lonely men and widows are so close that they can even hear the sound of the other party's heartbeat, which makes Li You, who is just at the age of blood and qi, have a physiological reaction.

"I'm sorry, I'm a little nervous." After he finished speaking, he didn't get a response from Xiaolan. Although she couldn't see her face, she knew from her low sobs that she was still worried about her teacher.

Beyond the wall, the original noisy sound was gone. I don't know how long it took, Xiaolan whispered, "There should be no one outside, let's go out." ”
