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

"It's not that I'm playing tricks here, it's that I've been ignoring something that almost made it impossible for us to pass through the Odd Formation." I retorted.

"Joke!! Just the few words we said earlier can solve the strange array? I think arrogant people always get nowhere. "Professor Twie has a very special look in his eyes when he speaks.

"Is that really the case?" Again, I asked, "Do you look like that when you're standing on the wall?"

"The city walls? Miscellaneous...... What city walls? This...... What's here...... What city walls? What the hell are you ...... What are you talking about...... What? "Hu Zaide had no idea what I was talking about.

"Am I wrong? Professor Twilight, Professor Twilight—" I said with a smile.

"Cheng Yin, what are you talking about, the more I listen, the more confused I become. Where are the walls in the barracks? Lin Yun asked with a wink.

"It is true that there are no walls in this barracks. However, isn't the Yiling Pass wall of the Wu army still standing in front of us? My words fell like a huge stone on everyone's heart.

"What does this mean? How is this possible? How could I be on top of the walls of an enemy army? Cheng Yin, I think you're crazy!! Must be insane!! I can't talk nonsense here, I don't know what to do!" Professor Twilight was visibly anxious.

"Cheng Yin, you don't mean to say that Professor Due Jiang is the enemy, right?" Lin Yun couldn't believe his ears.

"Okay, you're ...... Cheng Yin, you ...... You must be ...... It's deliberate, and next...... Doesn't it mean...... Say I'm an enemy too...... Enemy people? Hu Zaide's expression was angry, and it was more appropriate to say that he was angry.

"I see that everyone here is from the enemy army except for you Cheng Yin, right? I am, so is Hu Zaide, but what about Professor Wu? What about Lin Yun? Cui Li? I don't think you Cheng Yin can judge it with a word. Professor Twilight suddenly became proud.

"Cheng Yin, what Du Jiang said just now is indeed a bit excessive, but this can't be guessed, right? After all, we're on one front, aren't we? Professor Wu began to play a round game.

Cui Li walked up to me and said in a voice that only I could hear, "Cheng Yin, are you sure of what you said?" Although this twilight river always disagrees with us, after all, he has also come to this strange array, if we can't get out, he can't get out? It shouldn't be on the side of the enemy, right? ”

"Of course." My answer was simple and straightforward.

"I'm not speculating here, what I'm saying is the truth, Professor Duijiang, do you say yes? Oh, by the way, maybe it's more appropriate to call you 'the mystery man'? "I looked at Professor Twilight, and I watched all his reactions.

"Cheng Yin, what did you say? Professor Twilight is the 'mystery man' who stands on top of the city wall and obstructs us repeatedly? This...... It's incredible!" Lin Yun was completely confused.

"Hahaha!! Cheng Yin, I have to say that your ability to make up stories is still commendable, I'm a 'mystery man'? Jokes, big jokes, can you just put the identity of the 'mystery man' on me with just one word? If it's so easy, I would also say that you Cheng Yin is a 'mystery person'. Professor Twilight began to retort, apparently speaking to his sore spot.

"Cheng Yin, this is not a joke, what evidence do you have to say that Professor Dujiang is the 'mysterious person'?" Professor Wu cautiously confirmed.

"Evidence, what evidence can he have? It's not his own imagination. I don't believe he has any evidence that I'm the 'mystery man'. "Professor Twilight is visibly calm, and he seems pretty sure I can't find any evidence to prove his identity.

"Evidence, of course, I have ample evidence that he is the 'mystery man'." My voice was deep and powerful.

"Okay, then you can show it to us, and I'll see if your evidence is convincing." Professor Twilight is very confident, and it seems that no matter what evidence I present, he will deny it.

"Zhang Xinran, just when we first saw Zhang Xinran, his expression was panicked, but the reason for the panic was precisely because she saw one of us present." I gestured with my eyes to Professor Twie's direction.

"You just say bluntly that I don't do it, you don't need to go around in such a big circle, but Zhang Xinran just saw me panicked, it may be who I look like, and it is possible for her to misunderstand. Isn't it a bit hasty to say I'm a 'mystery person' just because of that? "Professor Twilight has a strong ability to retort logically.

"yes, wouldn't it be inappropriate to say that Professor Twilight is the 'mystery man'?" Lin Yun motioned for me to stop guessing like this.

"However, Zhang Xinran once said that she once saw the appearance of a 'mysterious man'." But I didn't mean to stop at all. "What you said is not wrong, but we were all here at the time, and Director Zhang was just about to say the name of the 'mysterious man' when he suddenly crossed over. No one knows who the 'mystery man' really is. Professor Wu looked helpless.

"That's right, Zhang Xinran crossed over just when he was about to say the name of the 'mysterious man', but his hand pointed at the 'mysterious man'." I said.

"This is even more wrong, it just means that I am not the 'mystery man' at all, don't forget that I have left at that time, this can only mean that the 'mystery man' is among you." Professor Twilight smirked.

"That's right, I remember that at that time, Zhang Xinran seemed to be pointing in the direction of Hu Zaide." Lin Yun thought back.

"How...... How could it be...... It's me!!! I don't...... Not that...... That 'mystery man', you ...... Trust me, I'm really ...... Not really!! As soon as Hu Zaide heard that the 'mysterious man' was him, he quickly denied it.

"I said that it will be Hu Zaide next, and unfounded suspicions will only make us farther and farther away from success." Twilight River was even more proud.

"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."
