"Dujiang, Cheng Yin's classmates are just guessing, don't take it too seriously, let's continue to study the countermeasures to attack Yiling Pass" Professor Wu tried his best to change the topic.

"Professor Wu, what I said is not wrong, Professor Dujiang is the intruder. And are you really Professor Twilight? I looked coldly at the man in front of me.

"What !!!!!!!!!!!!!!!!!!!" Cui Li looked at me with wide eyes.

"Cheng Yin, really don't be kidding. He's not Professor Twilight, who's Professor Twilight?" Lin Yun really thought I was joking, and if it weren't for my extremely serious expression, maybe I would have thought I was joking. But I know it's not a joke, and it's not funny at all.

"I ...... I was wrong before, and I ...... Cheng Yin is not in ...... Open with us...... Just kidding, he said...... Probably seriously, he ...... He's really crazy!! Hu Zaide's shocked look is still fresh in my memory.

Apparently my speculation once again shocked everyone present, like a bolt from the blue.

"Cheng Yin, this is really impossible, I have always been with Professor Dujiang, it is impossible for him not to be Professor Dujiang." Professor Wu argued.

"Is that really the case? We have always been accustomed to what we see, so when we see each other, it is easy to think that the other person is right next to us, but we all ignore the change of environment. What we are in now is not the real world we are familiar with, but a 'virtual world'. So what we see is not necessarily real. So the Professor I see must be the real Professor Twilight? I said unhurriedly.

"But I entered the Strange Array with Professor Twilight. I saw him walk into the light-walled space, and I was pretty sure it was Professor Twilight. Professor Wu was a little anxious.

That's right, according to what Professor Wu said before:

---- the three of us walked down the stairs and saw a lot of rooms blocked by the 'light wall', and we didn't want to enter it rashly. But who knew that the gunshots suddenly occurred behind us, and we thought that the man must have turned back halfway. Instead of that, we might as well take a risk and try the setting of this 'wall of light' in front of us, and maybe there is still a chance to escape. But when we approached, there was a sudden voice prompt, according to the voice prompt of these partition areas, only the door indicator light is not lit to enter, and only through one person, we entered here separately, but who knew that as soon as we entered the partition area, there was a light that I couldn't open my eyes, and when the light dimmed, I had already appeared here.

Professor Wu did enter the strange array with Professor Dujiang, and of course Hu Zaide also entered the strange array together. But we are still hindered by our preconceived notions.

"That's right, but once Professor Twilight enters the space of the wall of light, no one can see him anymore. At this time, the one who appeared in the strange array at the same time may not really be Professor Twilight. I continued my reasoning.

"Do you mean that after Professor Twilight entered the Strange Array, he was no longer the real him, and the person in front of us was the intruder with the gun?" Lin Yun's reaction was still very fast.

"I have a bold assumption that at that time, Professor Wu, Professor Dui Jiang and Hu Zaide entered the space of the light wall together, so that they would not see each other for a short time, but at this time, the intruder with a gun only needs to enter the space of one of the light walls, because after entering the light wall, the appearance and body shape of the characters will be recorded, so after the intruder with the gun knocks down the real Professor Du Jiang, he can continue to participate in this strange array with a fake Professor Du Jiang." I'm not done yet.

"Your reasoning is really full of loopholes, we all know that the space of the wall of light can only enter one person, how could that intruder enter the space of the wall of light where I am." 'Professor Twilight' is still arguing with reason.

"This is very simple, established thinking, we all thought that the door of the exhibition hall had been closed by Zhang Xinran, so why was it reopened, obviously this intruder knew this place very well, and he remembered all the organs here, so since it was in such a strict AEF research center, it was already free to come and go. Therefore, it should not be very difficult to enter Professor Twilight's light wall space. And there's another point that we've been overlooking. When we enter the Strange Array, all the people are on different sides, but why Professor Wu and Professor Hu Zaide and Professor Du Jiang are in the same place in the Strange Array, the answer is very simple, the intruder makes good use of the memory space, just like a person who has always been by your side, even if he has been away for a while, he will not be noticed too much by you. In this way, Professor Wu would naturally think that the Professor Twilight in front of him was Professor Twilight Jiang who entered the strange array with him, but in fact, the real Twilight River may have fallen in the space of the wall of light by now. I paused for a moment, then continued, "So the 'Professor Twilight' in front of us is not the real Professor Twilight. ”

"No wonder Zhang Xinran was so panicked when he saw him, it seems that this person is not only Professor Dujiang, but also the mysterious person on the city wall who has repeatedly obstructed us." Cui Li's thinking turned quickly this time.

"You're not Twilight? So who are you, and why do you have to get along with our professors in science? Who are you? Professor Wu asked angrily.

"I always felt that Professor Dui Jiang was like a different person after entering the Qi Array, but I didn't expect that you were really not the real Professor Du Jiang, what is your purpose?" Lin Yun asked.

"You...... You don't ...... It's not Professor Twilight, no wonder it's ...... before He also encouraged me to deal with Cheng Yin, saying that he was obstructing ...... Hindering the people who unraveled the strange array, no ...... Didn't expect you...... You're the one who owes me that...... So trust you!! "Hu Zaide was originally instigated by 'Professor Dujiang' to deliberately get along with me.

"You think the mystery is solved? You are just deceived by Cheng Yin's words, and the truth is not as he said. You're all wrong!! 'Professor Twilight' retorted.

"Twilight, no, intruder, now that the evidence is in front of you, do you still have anything to disagree with?" I asked out loud.

"Of course! I said your reasoning wasn't perfect!! "Professor Twilight said with a smile, "Now it's time for me to reason!"
