Cold ice can't break the water, and dead wood can meet spring again.

"Cheng Yin, let's continue to study how to capture Yiling Pass, let's put the identity of this 'mysterious person' aside for the time being." Professor Wu proposed.

"Yes, Cheng Yin, we don't have enough evidence to say who the 'mysterious person' is." Lin Yun also agreed with Professor Wu's opinion.

"Zhang Xinran did not point to Hu Zaide at that time, but pointed in the direction of Hu Zaide." I said.

"What's the difference?" Lin Yun asked.

"The direction of Hu Zaide is exactly the direction in which Professor Dujiang left." My words are clearly directive.

"The direction I left? You might as well just say that the 'mysterious person' that Zhang Xinran said is me. Professor Twilight sneered.

"Actually, that's what I've always thought, but people don't want to believe it." I didn't give in the slightest.

"Oh, apart from Zhang Xinran's vague hint, don't you have more powerful evidence?"

"Of course."

"Well, since you have other evidence, show it to everyone and tell them that I am the 'mystery man'. If not, please shut up and stop playing your boring mystery game, this is not a test game, and someone is walking around the building with a gun. ”

"I don't think that person has time to go for a walk, right?"

"What the hell do you mean?"

"Do you need me to say it?"

"You're wasting your time."

"I don't think so."

Talking to each other, Professor Twilight and I are like two generals in a competition, and every word, even every word, has infinite lethality.

"What the hell are you talking about? I'm getting confused, are you guys playing a guessing game? "Cui Li's words interrupted my 'competition' with Professor Dujiang.

"Cheng Yin, you can't get out on your own. Even if you try so hard and make promises, it's only a matter of time before you end up failing. Professor Twilight seemed to have something to say.

"How do you know I'm going to change."

"How do I know? I've always known that it's longer than you think, beyond time, beyond space. Or even an entire space-time! ”

"Who the hell are you?"

"Me? Who am I? Everyone here knows who I am except you. Am I just Twilight? ”

"You're not Twilight!" I'm sure of that.

"Not? I think you're the only one who thinks so. By the way, I almost forgot, what do you say I am? 'Mystery Man'? Professor Twilight laughed.

"That's right!! You're the 'mystery man'. ”

"Then I'd like to listen to your childish reasoning, I have never left you, I have been with you on a few expeditions, and I have seen that 'mysterious man' like you, how can I explain this?"

"Yes, Cheng Yin, Du Jiang is right, he was indeed with us when he went on the expedition, and he was standing next to me at that time. And the 'mystery man' was also standing on the city walls. Maybe I'm really mistaken, Twilight can't be the 'mystery man'. "Professor Wu is indeed reasonable, but he has neglected the most important point, which I only realized just now.

"It seems that your reasoning is about to end before it has begun, it's a pity, I really want to hear it." Twilight deliberately showed a very pitiful expression.

"Since you want to hear it so much, I'll tell you, it's not me who makes the mistake, it's our !!" My words aroused everyone's doubts.

"We? What did we get wrong? Lin Yun asked puzzled.

"I've always been thinking with my established thinking, but we haven't noticed that the environment in which our established thinking exists has changed."

"Change? What do you mean? Cui Li looked at me.

"To put it simply, if there were two Cui Li at the same time in your life, what would you think?" I threw the question back to Cui Li.

"Two mes, of course one is fake." Cui Li's answers are all reasonable.

"That's what we've always thought about, that it is impossible for two people to be exactly the same in the same plane. In other words, if I saw Cui Li in this class, then it would be impossible for Lin Yun in the cafeteria to see Cui Li at this time. Isn't that so? I looked around.

"Of course, if Cui Li was listening to the class at that time, then of course I couldn't see him in the cafeteria. Isn't that simple common sense? We are satisfied with Lin Yun's answer.

"No matter how simple it is, yes, that's what we all think in our hearts, but is that really the case? Will we be too confident? ”

"Cheng Yin, what do you want to explain? Does this have any established relationship with the question just now? "Professor Wu is a little inexplicable.

"Of course, Professor Wu, you are the key to unlocking this mystery, remember the scientific research meeting we attended in the AEF Building?"

"That scientific research society in the AEF Building? Of course, didn't I invite you to participate? How could I forget? But how can you talk about it further and further? What does this and that scientific research have to do with that? Professor Wu became more and more confused.

"That's right, it's the scientific research society, and that scientific research society will explain why Professor Twilight is in two places at the same time." I deliberately looked at Professor Twilight's expression at this time, and it was obvious that his expression was not as calm as before, and his facial expression was a little frozen. Looks like I'm getting to the point.

"What do you mean? Cheng Yin, you should hurry up!! Cui Li was a little anxious, and everyone was waiting for an answer.

"Professor Wu, why didn't anyone be shocked when two Li Ruina appeared at the same time at the Scientific Research Society?" My question has already explained a lot.

"Two Li Ruina? How is this possible? Cheng Yin, do you see two Li Ruina? "Cui Li's doubts have long been in my consideration.

"I also thought that the question was, the other Li Ruina is the artificial intelligence that AEF is committed to researching, that is to say, that 'Li Ruina' is actually a holographic projection, don't you all have RGU8, this is a truth." Professor Wu's answer was the answer I needed.

"Excellent! That's right, that 'Li Ruina' is a holographic projection, so why didn't everyone panic when it appeared at the same time at that time? In fact, it is very simple, the environment is the environment, and everyone will understand the things that do not conform to the usual thinking mode in scientific research meetings, and advertise the latest scientific research results. ”
