The soundproof barrier was divided into two layers.
The inner layer was completely soundproof. No sound from inside could escape, and no sound from outside could enter.
As for the outer layer, it was relatively soundproof. Sounds from inside could travel out, but sounds from outside could not travel in.
Because powerful dragon warriors had very strong senses, this wasn't just a soundproof barrier. It also shielded one's senses.
In other words, when answering a question, the two Dragon Emperor instructors would not be able to sense anything from the outside world. Unless Linghu Die 'er herself transmitted the question into the barrier.
This way, the possibility of cheating was eliminated.
"Let's begin."
Bian Feng didn't waste any time. He snorted coldly and walked to the center of the soundproof barrier.
Then, he closed his eyes and rested.
At this time, he couldn't sense anything from the outside world. It was time to ask Chou Jingyun his first question.
Chou Jingyun walked to the outer layer of the barrier and floated there. He closed his eyes and said, "Ask away."
He couldn't see anything from the outside world. He couldn't sense any aura from the outside world, and he couldn't hear any sounds from the outside world. Only Linghu Die 'er could transmit her voice into the barrier.
However, every sound Chou Jingyun made and every movement he made could be clearly heard by everyone in the outside world.
"Liang Xiao, you can ask your first question now."
Linghu Die 'er didn't take sides. After all, she wasn't sure if Kang Shin-mu was colluding with the Talisman Water Tribe. It was hard to say.
Her expression was slightly serious as she asked Liang Xiao.
Liang Xiao didn't hesitate and immediately asked his first question, "First question.
According to what you said, we colluded with the Talisman Water Tribe. When we killed Mengchuan, there were Talisman Water Tribe members surrounding him.
Then, may I ask, when did you rescue Lin Shuang?
Tell me the exact time! "
Linghu Die 'er relayed this question.
When Chou Jingyun, who was on the outer layer of the barrier, heard this question, his expression didn't change at all. He said calmly, "Three days ago, quarter past five!"
"Alright, let's switch."
Liang Xiao narrowed his eyes and waved his hand.
It was Bian Feng's turn to answer this question. Very soon, he gave the same answer: Three days ago, at a quarter past five!
Since they were planning to create something that didn't exist, they must have prepared the people, the time, and the place. They even knew how many people were on Kang Shin-mu's side, how many talismans did those water-kind people use, and why they didn't bring Kang Shin-mu and the others back when they saved Lin Shuang and the others, and so on … They must have prepared for all these obvious questions.
Therefore, Liang Xiao did not intend to ask these questions at all.
After hearing their answers, he nodded in satisfaction. Then, he asked the second question, "I heard that the Dragon Emperor instructors of the four Dragon Martial Academies are responsible for patrolling the battlefield to see if there are any powerful individuals who are stronger than the fifth level of the Dragon Emperor. At the same time, there are four groups of instructors patrolling the battlefield. Each group has two people, and they will patrol the battlefield of the nine races for a total of 24 hours. They will change shifts every night.
Then where were you patrolling in the two hours before five o 'clock? "
Even Linghu Die 'er felt that this question was too tricky!
This angle was probably something the other party had never thought of, but it was a reasonable question. Four groups of instructors patrolling the battlefield every day, and each group was patrolling for 24 hours. This was something that had been going on for a long time.
Liang Xiao's question hit the nail on the head. Since the other party was fabricating something that didn't exist, it was impossible for them to cover everything.
Some of the things they discussed were probably related to the scene and time when Kang Shin-mu killed Mengchuan. At that time, both parties must have been very clear about the details. No matter what Liang Xiao asked, they would be able to give the same answer.
However, Liang Xiao's question was too tricky.
Two hours before that happened, where were you patrolling?
When Linghu Die 'er relayed this question, Bian Feng answered first. He was stunned at first, then he frowned slightly. Obviously, this question was also beyond his imagination. He did not expect Liang Xiao to ask such a question.
In reality, this question had nothing to do with the case. This was what troubled him. The two of them had never thought about the answer to this question before this.
If they had to think about this question in advance, then they would have too many questions to think about in advance.
This was what Liang Xiao had just said. If they wanted to maintain a lie, they had to tell more and more lies and spread them out. They couldn't possibly answer all the questions in advance, could they?
"Two hours before 5: 45 PM, which is 5: 45 PM, Instructor Chou and I were patrolling the battlefield of the Demon Gods."
Bian Feng thought for a moment before answering.
He was speaking according to his and Chou Jingyun's usual patrolling habits. Usually, after patrolling the battlefield of the Demon Gods, they would head to the battlefield of the Water Race.
Then, it was Chou Jingyun's turn to answer this question. She came up with the same answer.
Patrolling the battlefield of the Demon Gods!
Both questions were quickly and accurately answered by them. Furthermore, their answers were exactly the same, as if they were speaking the truth.
However, Liang Xiao was not flustered. He asked the last question unhurriedly, "One last question.
When the Dragon Emperor Instructors patrol the battlefield, they follow a fixed route so that they can finish patrolling the battlefield of the Nine Races in the shortest amount of time possible.
"Therefore, every day, the four groups of instructors will meet each other at least once. Every time they meet, it is called a patrolling intersection. It is also convenient for the instructors to supervise each other."
At this point, Linghu Die 'er transmitted her voice to Chou Jingyun, who was supposed to answer the question now. The instructor's expression immediately turned ugly.
This question was a little far-fetched. Furthermore, it had nothing to do with the scene of Kang Shin-mu killing Mengchuan at all.
They didn't check so many things in advance!
Liang Xiao continued to ask, "My third question is, before you saw us kill Mengchuan, when was the last time you met another patrolling intersection? And which two Dragon Emperor Instructors did you meet?"
In other words, before they saw Kang Shin-mu colluding with the Water Race to kill Mengchuan, when was the last time they met another patrolling Dragon Emperor Instructor? And who were they?
These questions were actually two questions. However, when they were combined into one question, there was no problem at all.
Because if what the instructor said was true, then these two questions should be easy to answer.
But the problem was, they didn't check the answer to this question in advance!
When Instructor Chou Jingyun heard this question, he was dumbfounded. This … this question was too far-fetched!
Moreover, there were too many answers to this question. They could have answered the question several hours before that. There were three other patrolling groups of Dragon Emperor Instructors who could have met them. Most importantly, they didn't know who the three patrolling groups of Dragon Emperor Instructors were!
This was because they didn't patrol that day. The patrolling Dragon Emperor Instructors weren't them!
Who knew who the other three groups were and when they would be patrolling intersection?
This question caught him off guard.
