An apartment building near the Second Ring Road in Jin Ling City.
Director Li, who was standing at the door with Wang Peng, once again confirmed the address marked on the AR navigation. He then reached out and pressed the doorbell.
Not long after, a sound came from inside the door, and an unfamiliar voice sounded from the walkie-talkie on the door.
"Who is it?"
"It's me, Old Li, and Wang Peng … May I ask if Academician Lu is at home?"
The person behind the door went silent for a while.
The melodious voice continued to ring out.
"Mas — Academician Lu is out. He's not at home. Why don't you guys come back another day?"
"He's out …"
Director Li scratched his head. He obviously didn't expect Lu Zhou to be out. He didn't know what to do for a while.
Wang Peng, who was standing next to him, took a step forward and asked.
"May I ask who you are?"
"Huh? This question is quite embarrassing, I don't know how to answer it. "
Wang Peng and Director Li: "…?"
What do you mean you don't know how to answer it?
Director Li and Wang Peng didn't know what was going on inside, and they looked at each other strangely.
In the end, Director Li took the lead to break the silence. He coughed and spoke.
"Why don't we come back tomorrow? It's my fault I didn't ask Li Gaoliang to help us make an appointment in advance."
Wang Peng nodded.
"We'll have to come back tomorrow."
Xiao Ai, who was standing in the hallway, watched the two people leave through the door camera. He muttered.
"Um … As the hostess, shouldn't she invite the guests in for a cup of tea before leaving? But the master doesn't allow Xiao Ai to show his face in public. This is really troublesome … What do you think? (?????'')”
The scarlet pupils of the "Private-1" smart human guard standing next to him flickered slightly.
"Not Ling, not Ling … I don't quite understand what you're talking about."
Xiao Ai: "… Actually, I don't quite understand what you're talking about. _ (: з 」 ∠) _ "
…
Jin Ling University security department.
The dean of the mathematics department and Professor Sun Jingwen, who was in the class earlier, were both standing there.
In addition, there were two engineers in charge of safety.
An unknown person sneaked into the classroom and even caused such a big commotion, yet the school didn't know anything about it. No matter how you looked at it, it didn't make sense.
Dean Qin Chuan looked at the surveillance footage and saw a strange man standing in front of the whiteboard talking about the history of number theory. He muttered suspiciously.
"… Did Academician Lu say that?"
At least he didn't remember such a line in the history of mathematics.
Sun Jingwen stood next to Dean Qin, and he watched the surveillance footage from beginning to end.
After a moment of silence, he suddenly said.
"I want to go into seclusion for a while."
Qin Chuan looked away from the holographic screen and cast a questioning look at him.
"Is it because of what that man said to you?"
Sun Jingwen nodded his head and admitted this honestly.
"Under his guidance, I had some new ideas … about the Dirichlet L function."
Seeing that his student didn't seem to be joking, Qin Chuan immediately put on a serious expression.
"Go."
Sun Jingwen nodded and didn't say anything. He turned around and left the monitoring room.
The monitoring room returned to silence.
Qin Chuan, who was standing next to the engineer, stared at the holographic screen with surveillance footage. He seemed to be lost in thought.
From the perspective of a mathematician, the content that the man wrote on the whiteboard could be said to be quite insightful.
Especially the understanding of the unified theory of algebraic geometry, it was very likely that the man was even better than Lu Zhou himself.
Not everyone could make Professor Sun, who was stuck in a dead end, come to a sudden realization with just a few words.
Although the application of mathematics was widespread, the circle of mathematicians was not very large. If there really was such a nutty person, Lu Zhou couldn't say that he didn't have any impression of him. Even if Lu Zhou hadn't seen his face, he should at least have heard of his name and rumors related to him.
However, Professor Sun, who looked only about twenty-four or twenty-five years old, even surpassed Professor Sun, who won the Fields Medal at the age of 31 …
Is such a young man really possible?
Just as Qin Chuan's mind was in a mess, the technician was carefully comparing the images, trying to determine which department the person was from, or rather, which department the person belonged to.
Or at the very least, they wanted to collect some clues about his motive for suddenly appearing in class and his whereabouts.
However, the engineer standing next to the holographic screen suddenly made a sound of surprise.
Qin Chuan keenly caught the sound of surprise and hurriedly looked at him and asked.
"Did you find anything?"
"It's not that I found anything … It's just a bit strange?" The engineer with glasses stared at the person in the surveillance screen and said with a strange expression, "Didn't you notice? Around the outline of his face, there is a slight sense of image tearing … "
"You're right …" The other engineer apparently also noticed the problem. He frowned and added, "It's like two sets of incompatible holographic projection systems have overlapped, causing a small range of distortion in the outline of the picture."
"Maybe …"
"Maybe what?" Qin Chuan looked at the two people there and said anxiously, "Hurry up and tell me."
"He probably used some kind of facial retouching system based on holographic technology …" A strange expression appeared on his face. The engineer with glasses continued, "Although I don't know why he did this … This face shouldn't be his own."
Not his own face?
Which means he's wearing an optical mask?
Upon hearing this, Qin Chuan was slightly taken aback. His face was filled with confusion.
He really couldn't think of the person's motive for doing this.
At this moment, a possibility suddenly surged in his heart.
Could it be …
It's him!
Academician Lu?!
"Can you track where he went?!" Qin Chuan subconsciously blurted out. Thinking of this possibility, he immediately asked the engineer next to him.
"Our school's surveillance can only track the entrance of the subway station … After leaving the classroom, he went to the library, the old dormitory, and even the mathematics department's laboratory building. It seems like he went everywhere. But the last image seems to be in the library, and then I don't know where he went. "
"So it's him …"
It should be Professor Lu.
If Lu Zhou woke up and 100 years had passed, he would also want to go back to the place where he had lived.
Qin Chuan couldn't help but hold his breath. He was more and more sure of his guess, and his turbid pupils were also filled with strong excitement.
However, the strong excitement only lasted for less than a few seconds before it quickly turned into deep self-blame and shame.
If he wasn't disappointed in his descendants, why would he turn around and leave without saying a word?
Qin Chuan looked at the back of the person who turned around and disappeared from the classroom door in the surveillance screen. He sighed silently in his heart and whispered.
"Shame!"
"I'm really ashamed …"
While all the students at Jin Ling University were talking about their own affairs, Lu Zhou was sitting in the library at this moment. After sighing softly, he put down the book in his hand.
"… Looks like it's not here."
In addition to being a professor, he was also a student here for almost three years. Therefore, Lu Zhou wondered if the second key would be in the library.
After all, this was the place where he spent the most of his youth and sweat.
"Looks like Jin Ling University should only have one key. The other two keys should go back to the old house and the Jinling Institute for Advanced Study …"
Thinking about this, Lu Zhou returned the borrowed book to the bookshelf. As he walked out of the library, his index finger gently tapped on the necklace around his neck.
Soon after, digital ripples gently swayed along the contours of his facial features.
In the blink of an eye, the updated holographic image of him had completely changed into a different appearance, and he disappeared into the crowd …
