At this moment, Alan's muscles seemed to tense up. He stood still and did not dare to move at all.
Meanwhile, Li Zhuo was still sitting on the sofa with an expressionless face, as if did not have any reaction to Putnam's arrival.
Putnam looked at Alan with a hint of doubt in his eyes. However, soon, he put down his doubt and walked into the beverage room.
Putnam did not think too much, because he knew that it would be the same for anyone else.
Just as he was about to leave the room, someone suddenly pushed the door open.
At this time, any professional would be ready for battle. Those who did not react at all were either confident or a simple rookie.
Putnam did not say anything. He just silently walked to the bar counter and picked up the walkie-talkie on the bar counter. "A cup of hand-ground coffee. I want Brazilian coffee beans."
After saying that, he sat on the chair in front of the bar counter and closed his eyes to rest.
Seeing that Putnam did not communicate with them, Alan sneaked a glance at Li Zhuo. Just now, even an expert like him became nervous, but Li Zhuo did not have the slightest reaction.
At this moment, it was very difficult for Alan to distinguish which kind of situation this young man was in.
It was clearly more likely that he was a 'rookie', but Alan saw Li Zhuo's expression. From the beginning to the end, there was not the slightest change.
Was this guy really an ordinary person?
Li Zhuo noticed Alan's gaze, and he said calmly, "let's go to the recreation room."
Alan was slightly stunned. Only then did he realize that he had planned to go to the recreation room just now. However, because of Putnam's sudden appearance, he had forgotten about it for a moment.
"Okay." Alan replied in a flat tone. Before he left, he glanced at Putnam again to make sure that he was not observing him. Only then did he leave the beverage room with Li Zhuo.
After closing the door of the beverage room, the two of them walked in the corridor in silence, not saying a word.
Alan wanted to make sure that any conversation would not be heard by Putnam.
In fact, he was worried that the conversation in the beverage room might have been heard by Putnam. If that was the case, Putnam would probably know that he and Li Zhuo were investigating him.
This was not good news.
After walking for a long distance, Alan finally voiced out the worry in his heart. "Li, do you think Putnam heard what we said just now?"
"No," Li Zhuo said calmly.
"Why?" Alan was slightly stunned. He did not expect Li Zhuo to give him such an answer, and it was in a very positive tone.
"Because he was wearing wireless headphones, and the headphones were playing music."
Li Zhuo's tone was still calm.
"I also saw the headphones, but maybe the headphones were not playing music. We can't be sure about that!"
Alan frowned slightly. He felt that this young man in front of him was really too immature. Wearing headphones did not mean that he was definitely listening to music!
However, Li Zhuo once again used a very certain tone to say, "no, he must be listening to music."
"Your words are completely groundless. It's impossible for you to hear the music in his headphones."
Alan's brows furrowed even more tightly. He even felt that Li Zhuo was deliberately thinking in an optimistic direction.
Almost everything in Section S was the best in the world, and the headphones that Putnam wore were naturally the best.
Outsiders would not be able to hear the music in the headphones, so it was impossible to tell if the headphones were playing music.
However, Li Zhuo calmly explained, "I didn't hear the music in Putnam's headphones. I don't have that good hearing. This is what my vision has helped me confirm."
"Vision?" Alan was slightly stunned.
What did the music in the headphones have to do with his eyesight?
The two of them continued to walk along the corridor without making the slightest sound of footsteps. The silence made Alan feel that the young man in front of him was particularly mysterious.
Li Zhuo slowly said, "you should also know that sound is produced by vibration."
"Although I can't hear the music in Putnam's headphones, I can see that his headphones are vibrating."
"Although the amplitude is very small, it is indeed vibrating, and it is very dense."
"..." Alan was speechless once again.
He was completely shocked. Indeed, no matter how good the sound insulation effect of the earpiece was, it would definitely vibrate.
This kind of vibration could be clearly felt by the person wearing the earpiece, but it was very difficult for outsiders to feel it.
So, this youth in front of him could actually see that Putnam's headphones were vibrating? This was simply inconceivable!
Li Zhuo continued to explain. "If Putnam had been walking around, it would have been very difficult for me to see it, because there was no comparison."
"However, Putnam just stood at the door for two seconds, and also stood at the bar for a few seconds. Before we left, he had been sitting in front of the bar and had not moved."
"As long as he doesn't know, I can see if his headphones are vibrating. It's very simple. There is a contrast between the images."
The corners of Alan's eyes twitched. He understood the principle of the headphones vibrating. He could see the subtle contrast between the still images, and he also understood it.
However, every vibration of the headphones occurred in a very short period of time. The difference between the two so-called 'still images' might need to be compared with 'frames' to see if the earphone was vibrating.
You call this simple?
Looking at the calm young man beside him, Alan finally could not help but ask the biggest question in his heart.
"Are you really just an ordinary student?"
Allen was very sure that Li Zhuo was very relaxed after seeing Putnam. This was definitely not the performance of an ordinary student. Only a truly capable person could have this kind of 'relaxed' confidence!
"Yeah." Li Zhuo continued to look forward, and his tone of reply did not change at all.
"But... when Putnam appeared just now, your expression did not change at all... This is not the reaction of an ordinary student." Alan stared at Li Zhuo closely, as if trying to catch a reaction.
Li Zhuo finally turned his head to look at Alan, and the two of them walked forward while looking at each other.
When they reached the next intersection, Li Zhuo suddenly spoke. "Have you heard of a sheep called 'fainted sheep'?"
Allen did not reply, because he did not understand why Li Zhuo would suddenly mention this.
Li Zhuo did not seem to want an answer from Alan and continued to speak on his own. "This kind of sheep has a disease called congenital myotonia. When they are frightened, their bodies will tense up, so they will fall."
"I'm a little similar to them..."
"As long as I'm nervous, my facial muscles will become very relaxed, and I won't be able to make any expression..."
Alan was stunned when he heard that. There was such a disease in this world?
So, this kid gave off a very relaxed feeling because he was really 'relaxed'?
