"Of course I can hear my own voice, that's why I think it's weird!" Gu Fan looked nervously again: "I obviously didn't take the initiative to enter the thinking room, how could I hear your voice!" ”

"Well...... Xiao Zifan's voice paused, he was silent for a while, and then said, "I don't know much either...... If I have to explain it to you...... It's like I suddenly jumped from a lower dimension (the mind room) to a higher dimension (here). Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info or ......"

"Or?"

"Or ......" Xiao Zifan continued: "You have suddenly been downgraded from a higher dimension (reality) to a lower dimension (here)...... In short, although my current dimension is still lower than yours, it is no longer 'one' gap, and we may only be 'half a dimension' short now, so I can talk to you directly. ”

"I don't feel like I understand......" Gu Fan scratched the back of his head and said slowly.

"That's not right...... he seemed to think of something suddenly, "You couldn't talk to me directly in the game before, right?" Could it be that the dimension here is half a level lower than in the game script? ”

"This is also something strange about me......" Xiao Zifan's voice was a little solemn: "In short, everything is careful...... It stands to reason that you should be teleported to a personal stronghold now...... There's something weird about this place! ”

Gu Fan was about to speak, but suddenly heard a distant bell......

"This voice is ......," Gu Fan muttered.

"Class, class...... Hurry up! ”

"I'm running!"

On the asphalt road, which was originally empty, a group of passers-by in a hurry suddenly appeared, and they passed Gu Fan, who was still standing in place and was stunned, and ran towards the direction of the bell ringing at a fast speed.

"This big brother ......" Gu Fan grabbed a man with glasses who passed by him and asked, "Where are you going?" ”

"Who are you?" The man with glasses glared at Gu Fan with some dissatisfaction, but after seeing his tall figure and strong little arms, he obviously coaxed, and his tone became a lot more relaxed: "I...... We're going to class, we're going to be late! ”

"Class?" Gu Fan asked in surprise.

"Well, that's right!" The man with glasses nodded: "Today is the day when the famous physicist Peter Pan holds a public lecture at our university......"

"Peter Pan?" There was some doubt in Gu Fan's eyes: "Are you sure his name is not Peter Pan?" ”

"Peter Pan's surname is Pan, and he is a physicist in our Huaxia District...... What Peter Pan ......" The man with glasses muttered, and when he saw Gu Fan loosen his cuffs, he hurriedly hurried along the crowd in the direction of the bell.

"This name is a bit weird......" Gu Fan touched his chin and groaned.

"Whatever, go check it out!" Xiao Zifan urged in Gu Fan's mind.

"It's also right......" Gu Fan thought about it, and then took a step forward and followed the crowd rolling forward.

……

Gu Fan followed the crowd to a silver-gray building, everyone rushed in front of the open door, Gu Fan entered the gate, and found that it was actually a huge stepped conference hall, at this time, there were already many student-like observers sitting on the stepped seats in the conference hall, but perhaps for some reason, the seats closest to the podium were still quite empty. At the bottom of the conference hall was a very bright and beautiful silver-white stage plane, and a lectern table was placed in the center of the stage, and a slender man was standing next to the lectern.

The man looked to be in his early thirties, with a very energetic hairstyle, round-rimmed glasses with gold rimmed, and a very ordinary black suit, and he was holding his head down and playing with a silver coin in his right hand.

Gu Fan squinted at him, and then found a position near the podium and sat down.

"Looks like everyone is almost there." The man on the podium looked up, glanced at the almost full staircase seat, put the coin in his hand into his trouser pocket, and said with a smile: "Hello everyone, let me introduce myself first, my name is Peter Pan...... It's not the Peter Pan ...... on Neverland."

This slightly self-deprecating self-introduction earned him a few scattered laughs, but it soon fell silent.

"As you can see, I have been invited to give you a public lecture...... Of course, it doesn't matter if it's an open class. ”

"I'm sure there are a lot of people sitting in the staircase hall right now...... I even bet there aren't many physics majors out there. ”

"So the open class I'm going to talk about today has little to do with cutting-edge physics, and the physics students who came here are probably going to be disappointed."

"But if you're really interested in cutting-edge physics, you might as well go directly to the Internet and download my free physics lesson plan, and you don't have to go through all the trouble to listen to any public classes."

"Okay, no further ado...... Today, I don't want to mention anything too advanced about physics, but I'll talk about parallel universes that you've all heard of. ”

"Parallel...... Universe? Gu Fan lowered his eyebrows and leaned forward with interest, hoping to get closer.

"Okay, in order to let more students put down their mobile phones and enter the problem we are going to discuss today as soon as possible, I will randomly select a few students to talk about their understanding of parallel universes." Peter Pan lifted the golden frame, smiled and nodded to a girl with a ponytail sitting in the first row: "Come, this classmate, you can tell me what parallel universe means." ”

"Parallel universe, ah......" The girl who was pointed out was obviously a student from another department, a trace of confusion flashed on her face, and finally she said with some hesitation: "Probably...... Probably in another world exactly like us, there is also a me, right? ”

"Very good!" Peter Pan smiled and encouraged, and then nodded to the boy next to the girl: "This classmate, you can talk about it." ”

The boy slowly stood up, lowered his head and thought for a while, and said in a thoughtful tone: "The so-called parallel universe is not two identical worlds, but a certain person, or a certain group of people, and for these people, two completely different worlds...... A world that is not related to each other. ”

"Hmm...... Like me...... My name is Zhang Heng" The boy then explained: "Maybe in a parallel world, there is also one who looks exactly like me, and his name is also Zhang Heng, all of our personalities and physical states are exactly the same, but the only difference is that Zhang Heng in that world is a billionaire......"

"This is a parallel universe."
