The afternoon sun quietly sprinkled on Mo Yuan's face. Pedestrians around them paced slowly, enjoying a leisurely weekend afternoon. A child ran past Mo Yuan's side with a smile, and Mo Yuan, who was sleeping on the open-air coffee table outside the museum, suddenly exclaimed, "Water!", straightened up, fell off the chair, and woke up. When he opened his eyes dimly, he still seemed to be able to hear the roar of the sea falling from the sky in his ears, and he still seemed to be able to see those ancient cuneiform characters in front of him.

"What time is it?" Mo Yuan's first thought after waking up was to confirm the time, the experience of this time has gradually made him adapt to the situation of "things are not people" at any time, and time is an important clue for him to confirm his experience. He looked at his phone's screen, "13:46:00".

Mo Yuan's mood eased slightly, "Fortunately, it's only a minute later than the scheduled time." The purpose of this trip is not to die prematurely", Mo Yuan wanted to move the chair he was sitting on, but the chair did not move at all, Mo Yuan then remembered that he could not interact with the things in this dream "history" that had happened, "However, it is still a little strange, the so-called can't interact, strictly speaking, I shouldn't be able to sit on this chair, I should be like helping that little girl, being passed through like air." But now I can sit in a chair and take a nap on my desk. Mo Yuan thought for a moment, "Even so, because I can't move these objects, the 'history' has not changed, if someone wants to sit on this chair next, he can still sit, and the entire recorded 'movie' has not changed because of my appearance." Then again, if I can't even sit on a chair, then strictly speaking, I can't stand on this earth, and everything passes through me like air, I can't exist in this world at all, and if that's the case, then it becomes impossible to observe 'history', because I can't exist in this history at all, how can I observe? Professor Wu Tian must have realized this a long time ago, so the so-called recording of dreams becomes' History', re-entering history, can only observe, cannot interact with any object in the dream, there are more detailed rules: I can't have any interaction with the characters in the dream history, because it will change history, but as for the environment in the dream history, I can still 'touch' in the physical state, sitting in a chair as I do now, but I can't 'move' the element, because doing so will change the 'history'. Professor Wu Tian is really a powerful person, and he has thought it through. ”

After admiring Professor Wu Tian for a while, who was about to connect with the 'self' in history, Mo Yuan thought about the experience just now, he remembered that in that experience, he had confirmed the time, which started at "13:45:00", and when he woke up again, the time had already come to "13:46:00". This experience that made him frightened and tormented lasted only a minute, and he himself felt unusually long, "Maybe it's because of the pain, it feels long." Mo Yuan laughed at his panic in the experience just now.

"But what is going on in this minute?" Mo Yuan pondered, "There are two possibilities: first, when I access the experience system to enter my dreams, the time point is set to 13:46:00, and the experience between 13:45:00 and 13:46:00 belongs to the experience that the human experience system 'free' gave me to me; :45:00, but, after accessing, I fell asleep in a chair outside this café and dreamed for a minute. If it is the first possibility, unless Wu Xin did it on purpose, otherwise, there is something wrong with this experience system, but why did Wu Xin do this? Let me suffer a little to punish me for cheating on her before? If it is the second possibility, then Wu Xin did not treat me badly, the system has not made a mistake, everything is normal, but why did I have a strange dream as soon as I entered the system? Hey, no matter which possibility, there is something uncomfortable that people care about. ”

A pop song is playing in the café, and the singer is hoarsely shouting, "Your vows are like a brief twilight."

"Has the interceptor been loaded successfully?" Wu Xin asked.

"It has been loaded successfully, and the dream construction data of the 'experience system' is being simulated to be obtained by the 'experience system access device', and the feedback data sent by the experience system access device is also being simulated to be obtained. Wu Xin's staff replied.

"Good. According to his father's design at that time, the dream history played back by the human experience system playback subsystem can only be accessed by the participants who have appeared in the dream, and in order to ensure that this purpose is achieved, all dreams are encrypted when they are recorded, and the key is the biometric characteristics of the participants in the dream, and only he knows which features are collected and what kind of encryption algorithm is used. Originally, I wanted to look at the recorded dream experiences of others when I was bored, and pass the time, but because of his design, it came to naught. Now......" Wu Xin looked at the two men lying on the two 'empirical system life support subsystems'—the "sofa beds" she jokingly told Mo Yuan—one was a father who pretended to be a plant, and the other was a writer who thought he could save his father, "but no one could stop me from doing my little experiment." ”
