"Cheng Yin, having said so much, what is that obvious mistake? We really didn't send it. Cui Li said impatiently.

"Yes, what kind of obvious mistake is Cheng Yin, even the 'mysterious man' has not been able to find out." Professor Wu also asked.

Many times preconceived notions are always deeply influencing us, and whenever we are always confused by the scene in front of us, even if the real image is placed in front of us, we avoid it. Now the same question came to me again, but this time I had to find the right answer.

My brow furrowed, and I didn't say a word.

"Cheng Yin." Lin Yun shouted my name.

"Don't you pay attention? When we first entered the 'Odd Array', the people around us used ancient languages, and although we didn't need to communicate with them in ancient languages, their language was still the language of that era, but then it quietly changed, and there was a language that was sometimes ancient and sometimes modern, but because we were already used to the modern language, even if they unintentionally switched languages, we didn't feel it. "I suddenly recalled that when I was walking in the barracks just now, I heard the soldiers talking about Zhang Xinran's 'crossing'.

----- "Two days later, the day of the decisive battle, my heart is always so unsteady. A few soldiers around him were chatting.

"Yes, I don't know if I can capture Yiling Pass."

"I've heard that the 'mysterious man' on the city wall seems to be a friend of the general."

"Really?"

"No, I've heard about it, and it seems to be true."

"How so? Then do you think we can still attack Yiling Pass? ”

"It's hard to say..."

It was the conversation of the soldiers that made me realize that what I had always taken for granted was not really like that. It's like when we hear Chinese around us, we always naturally think that we are in China, but in fact we are probably abroad at this time.

"Language?" Lin Yun suddenly realized something: "You're right, when we first entered the 'Qi Array', almost all the people around us used ancient Chinese, and I couldn't adapt to it for a while, but then it did change unconsciously, and we can often hear modern language." Lin Yun recalled.

"I didn't even notice that there was this detail." Cui Li said.

"But what does this have to do with that 'mystery man'?" Zhao Yuyu asked the crux of the question.

"If we think about it carefully, it is not difficult to find that this change is before and after Cui Li crosses, that is to say, at this time, the 'mysterious man' is modifying the system framework structure of the 'odd array' and turning off the exit function on our electronic bracelet." I said.

"That is to say, it was not Cui Li's 'crossing' that attracted the attention of the 'mysterious man' and thought of modifying the 'strange array', but that he was already modifying the framework structure at the beginning, but Cui Li came back after leaving, and it happened to be the 'mysterious man' who completed the modification." Lin Yun's speculation is reasonable.

"No wonder, I just thought that Cui Li's 'crossing' was a matter of a while, how could that 'mysterious man' modify the framework structure of the 'strange array' so quickly." Zhao Yuyu said.

"That's right, I think that 'mysterious person' must have started to modify the system before entering the 'odd array', and it was only when Cui Li inadvertently pressed the button that the modification was completed, which prevented Cui Li from leaving." I went on to add.

"But you still haven't said why the 'mystery man', that is, the intruder, is not the staff who participated in the design and construction of the 'Strange Array'?" Li Ruina returned to the original position.

"Just imagine, the design participants of this 'odd array' must be senior engineers or elites in the field of county officials, and they must have a deep understanding of the 'odd array'. There was a problem with the locale that was set before, and if that 'mystery man' was one of the builders back then, it was absolutely impossible not to find this obvious mistake, so there was only one possibility. "I'm not done yet.

"It's just that this 'mysterious man', like us, has never understood this 'strange array', so when he enters the strange array after modifying it, it is naturally impossible to find this mistake." Lin Yun's reaction was indeed very fast, no wonder she and Zhang Han had passed the Lost Garden test a long time ago.

"But since he is not familiar with this 'odd array', how can it be possible to modify the information framework structure of this 'odd array'?" Cui Li questioned.

"This question is very simple, Cui Li, the assembly workers in the factory do not understand the design principles and related concepts of assembly machinery, and why can the parts be assembled in good condition?" I asked.

"This ......" Cui Li felt like he was trying to think, but there was no answer.

"Drawings!" Lin Yun replied perfectly.

"That's right, it's a drawing, as long as there are relevant design drawings, even ordinary engineers can modify it, but at the same time, it is easy to make other mistakes." I looked at Li Ruina and asked, "Is there any design drawings for this AEF research center?" ”

"Design Drawings...... Yes, yes...... However, these drawings are in the central storage room of the AEF building, and it is absolutely impossible to obtain them. Li Ruina didn't believe that anyone could get their hands on the design drawings of the central depository.

"Let's think about this problem later, the top priority now is to find a way to unravel this 'strange array', and this is the only way to get us out of here." The reasoning game should also be stopped for the time being, and we have more important tasks ahead of us.

"Yes, we still have to think about how to unravel this 'strange array' as soon as possible, otherwise we won't be able to get out of here." Professor Wu said worriedly: "All the methods we thought of before have been invalidated, and now we can only think of other ways from scratch." ”

"The mechanism of Yiling Pass is complicated, and it is not so simple to unlock it, although we have found out the 'mysterious person', but we still have no way to capture Yiling Pass." Lin Yun said helplessly.

Indeed, we don't have any better way to capture Yiling Pass now, all the methods have been considered, but they are still at a loss.

The night passed quickly, a new day was coming, and I watched the sun shine through the window into the military tent, and after tomorrow was the day of the decisive battle.

The morning sun sprinkled on us was very warm, and we felt a force guiding us forward.
