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

"Are you going to keep making up stories again? Very well, I'd like to see how you justify yourself, but you can tell us why you are only suspicious of me among so many people. "Professor Twilight" asked, looking at me.

"First of all, you are wrong, I don't suspect you as the intruder now, I don't think you are the intruder at all!!" I looked at "Professor Twilight" with great imposingness.

"Sure? Hahaha, maybe your self-confidence is your only merit. Why are you always so confident? Always look like you can change the world? But what can you do in the end? It's just that nothing can be changed, nothing can be changed. Anger appeared in Professor Twie's eyes.

"Who the hell are you? What exactly is your purpose? "I always felt that the person in front of me was so familiar, and although his words and words had changed deliberately, the words that came out from time to time always felt so familiar to me.

"Didn't you continue reasoning? Why did you start asking me rhetorically, if I knew the answer, do you still need to reason? "Professor Twilight" visibly changed the tone of his voice.

"Cheng Yin, tell me why the intruder is the 'Professor Twilight' in front of us and not anyone else?" Professor Wu turned the question back.

"This is the answer your words gave me, you said before that you came to the Wall of Light. Hear gunshots behind you? I asked.

"That's right, 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 rush in. But who knew that the gunshots suddenly occurred behind us, and we thought that the man must have turned back halfway. What Professor Wu said was exactly the same as before.

"So that intruder is at the exit of the Qi Array at this time, but at this time we have already come to the Qi Array, so according to this time difference, that intruder cannot be Lin Yun and Cui Li." I've used the method of elimination here.

"But in this way, Professor Wu and Hu Zaide still have doubts." Lin Yun's judgment is very accurate, and I have doubted Professor Wu and Hu Zaide before. However, I quickly dismissed Professor Wu's possibility, not because he didn't want to always go against me like Professor Jiang and Hu Zaide. Rather, I noticed a subtle detail, and it was this detail that allowed me to dispel my suspicion of Professor Wu.

"Cheng Yin, I'm not an intruder, I'm really Professor Wu." Professor Wu is desperate to prove his identity.

"It won't be Professor Wu." My judgment seems somewhat arbitrary.

"Why are you so sure it's not Professor Wu, do you really know him? Maybe he's the real intruder. "Professor Twilight's" words were clearly provocative.

"It's simple, one keyword." I looked at Professor Wu, who was nervous: "When a person is nervous, everything that can be disguised will become clumsy. However, Professor Wu has always referred to me with the word classmate, and it is precisely because of his long-term teaching relationship that it is impossible for ordinary imitators to use these two words from time to time, so Professor Wu is not the intruder. "Actually, there are no two, and I wouldn't believe that Professor Wu is the intruder. After all, many times a person can feel the sincerity of another person.

Like now, I can't even guess what 'Professor Twilight' thinks.

"What about Hu Zaide? I think he has a big chance of doing that too. Cui Li turned the question to Hu Zaide again.

In fact, I have always doubted Hu Zaide, after all, he always helped each other with 'Professor Twilight', and many times put me in a very difficult situation.

"Actually, I really thought about whether it was Hu Zaide, or maybe both of them had big doubts, but just now, I suddenly realized that it was not Hu Zaide.

"Just now? Could it be that Hu Zaide's words just now made you clear your suspicion? Lin Yun asked.

"Of course not, have you noticed a detail about Hu Zaide. Probably not a single detail. I added.

"The details? What are the details of Hu Zaide? Is it a stammer? That's right, it's his unique stammering, which can show that he is Hu Zaide. Cui Li was as happy as if he had done a math problem correctly.

However, Cui Li's point of view gives the answer from another aspect. Although it is not quite the same as I imagined, it can show that Hu Zaide is himself.

"Stammering, that's a good point, it's not quite what I thought, but it's the same as it is." I agree.

"Cheng Yin, what is your point of view?" Professor Wu confirmed.

"It's a leg injury, Hu Zaide was already injured when he entered the Qi Formation, his leg injury has not healed all this time, I can clearly see that he walks a little slowly, just now when he left the military tent, he is not very flexible. So Hu Zaide is also himself. "I can stop my reasoning for a moment.

"So 'Professor Twilight' besides you, it's really hard for me to find a better candidate than you. Is there anything else you have to say? I glared at Professor Twilight, and all the puzzles had been solved.

"Sure enough, it didn't disappoint me, your reasoning is really wonderful, and it seems that there is no need to hide it from you anymore. But don't think you've won, the real battle between us has just begun. "Professor Twilight" turned around, and suddenly appeared in front of me, and you are no longer "Professor Twilight". It's the mysterious man with the cloak. The cape is very low, and it does not allow for the appearance of his true face.

"You're the mystery man!!!!" Cui Li's anger is not in one place.

"How's that!! I didn't disappoint you, I am the 'mysterious man' on the city wall, so every one of your previous plans has not succeeded, and one of them is my efforts. Hahaha!! The mystery man burst out laughing.

"You've got it !! come out" Cui Li couldn't control it and threw a punch at the mysterious man, but like a holographic projection, Cui Li's attack was completely ineffective.

"I don't have time to play with you anymore, let's see each other on the battlefield of Yiling, seriously, I'm looking forward to your performance!!" The mysterious man disappeared in front of us after saying that. It's like crossing over.
