In the early summer afternoon, the lazy sun caresses the lawn, stirring up the unique fragrance of the grass and trees, the breeze is gentle, and the plane trees sway their mottled shadows, hovering on Wu Xin's beautiful face.

Suddenly, the sleeping Wu Xin slowly opened his eyes.

"Where am I, and what time am I now?" Wu Xin muttered to herself, sitting up her upper body, leaning against the plane tree behind her, her legs resting on the soft lawn.

"CC University, eighteen years ago. Xiao Feng, who had already woken up beside Wu Xin, said.

"Ahh ”

"Oh, little brother, have you ever woken up in a bad dream?" Xiao Feng asked.

"It's not bad, it's just not as comfortable as it is now," Mo Yuan replied, "There is a question that I have always wanted to ask. ”

"Say it, little brother. Xiao Feng stretched out his fingers to feel the comfortable and warm sunshine while saying casually.

"What should I call you?" Mo Yuan asked, "I don't think you actually like to be called 'senior' or 'Sister Xiao' because you are so young. ”

"Haha, I'm very young," Xiao Feng said happily, "It's good to call him by his name, when there are many people, find some honorific titles, such as professor, senior, boss, and let me hold up some scenes in front of those worlds, a little prestige, although, I never think that those are titles from people." ”

"Then I keep calling you 'Sister Xiao', are you unhappy?" Wu Xin was a little reluctant.

"It's okay, I'm really a few years older than you, you call me sister, it's fine, if I'm younger than you, it's too unfair...... Hahaha" Xiao Feng didn't seem to care about what he said, "As for Mo Yuan, he is indeed older than me. ”

"Are you telling me the secret of your youth?" asked Mo Yuan.

"I'm just telling you that I do have a secret, but I'm not going to tell you what a secret it is. Xiao Feng winked at Mo Yuan, "Secret is the source of fun. ”

"Oh, I have no interest in this secret, no matter how long the night is, no matter how short the dawn is, it is still the dawn. Mo Yuan said something that made people confused.

"Yes. Xiao Feng said, standing up, "Let's talk while walking." ”

"Good. ”

"Good. ”

On the boulevard, some students walked by in twos and threes, and it was an ordinary scene.

"These aren't real people, are they?" Wu Xin asked.

"Yes, this dream is only accessible to the three of us, and everyone else you see now is simulated by computer programs. Xiao Feng said, "They can have simple interactions. ”

"Hello, classmate. Xiao Feng stopped a student who happened to be passing by.

"Hello, is there anything I can do to help you?" the student asked.

"How do I get to the School of Computer Science?" Xiao Feng asked.

"Go straight along this avenue, and when you come across an intersection, turn left and continue walking for a while, and you arrive. The student replied.

"Thank you. Xiao Feng said, turning to Wu Xin and Mo Yuan, "It's like this simple interaction." ”

"It's really like a real person. Mo Yuan said.

"Are the participants in the dream you entered before all real humans?" Xiao Feng asked.

"I guess so, though, I know of the existence of procedurally simulated humans, but this is the first time I've seen it with my own eyes. ”

"Sister Wu Xin, you have to give your assistant more opportunities to practice. Xiao Feng said.

"Well, yes, after that, I'll arrange it. Wu Xin said, glancing at Mo Yuan.

Mo Yuan knew that Wu Xin was referring to "that" place.

"Isn't it, as the main creator of the human experience system, they all enjoy the power to access the experience system at any time? I remember that Wang Cheng was free to access the experience system in his own laboratory. Mo Yuan confirmed.

"Yes. And, it's not just our main founders, in fact, a lot of powerful people have that power. Xiao Feng replied.

"Sister Xiao, this is the first time I've heard this. Wu Xin said.

"You're a stupid researcher, if it weren't for this assistant, maybe you would have been victimized a long time ago. Xiao Feng said.

"I'm not stupid, am I, Mo Yuan?"

"Not stupid, not stupid. ”

"Since these powerful people can access the experience system at any time, it means that they don't need to go to the human experience center in person, right?" Wu Xin asked.

"Yes. ”

"Obviously not to experience different histories and environments at any time, right?" Wu Xin asked.

"Naturally not. ”

"What's that for?" Wu Xin asked.

"Perhaps, the human experience system can provide much more than just an 'experience' on the surface. Mo Yuan said, "At least, now I understand that there is another use for this system." ”

"Oh, little brother, tell me about it. ”
