Later, Xie Liuyun personally tested Sheng Qingfeng's hearing and found that after wearing earplugs, Sheng Qingfeng's ability to capture sounds was greatly enhanced.
Therefore, Huang Hanhan ridiculed Sheng Qingfeng and had a pair of "sound ears".
This reminded Xie Liuyun of the "eavesdropping device" he had heard of before.
But he was only limited to this consideration.
Xie Liuyun was not prepared for Yong Ming's question now.
Since you are not prepared, you can only admit that you don’t know.
Therefore, Xie Liuyun shook his head and said very honestly: "Ming Gong, I haven't thought about this question, so I can't answer you."
Yong Ming nodded, glanced at Xie Liuyun nonchalantly, and said to Sheng Qingfeng: "Qingniu, you are someone who has tried on these earplugs, so you naturally have a say in the use of earplugs.
I first explained the function of this kind of earplugs, which is to reduce loud external sounds to a range that can be heard normally.
The second function of this earplug can be tested after you try it on.
Earplugs can amplify the slightest sounds from the outside world to a range that can be heard normally.
Next, there is the third function of earplugs. Qingniu, have you ever considered this?"
When Yong Ming finished speaking and looked at Sheng Qingfeng, there was no pause, and everyone immediately heard Sheng Qingfeng's answer.
"Ming Gong, I just took a closer look at the earplugs you gave me.
I found that there is a dark red mark on one end of the earplug.
This dark red mark is designed to be very secretive and difficult to be discovered.
In addition, this earplug is magnetic, which reminds me of a compass.
I guess the third function of this earplug is to help the user of the earplug to identify the direction and determine their own position when traveling in the wild.
I don’t know if what I said is right or not, please give me some advice.”
After Sheng Qingfeng finished speaking his opinion, he saw Xie Liuyun nodding.
He immediately smiled knowingly at Xie Liuyun, and the two of them had a tacit understanding.
Because Xie Liuyun had come into contact with earplugs before and had a feel for the feel of earplugs.
That is a feeling that only magnetic materials can leave people with.
When Xie Liuyun was in college, he was exposed to magnets and magnetic materials in experimental classes and materials classes, and he was very familiar with the feel.
Therefore, when he got the earplugs just now, he judged that the surface of the earplugs was coated with a layer of magnetic material.
Otherwise, this kind of earplugs would not be magnetic.
Now Sheng Qingfeng, who is interested, guessed from this feature that this earplug has the function of a "compass".
Moreover, from the fact that Sheng Qingfeng immediately responded to Yong Ming after asking the question, it can be seen that Sheng Qingfeng has already thought carefully about this issue.
It can be seen that he has been conducting research and analysis around the earplug situation.
Simply on this point, Xie Liuyun had to admit that Sheng Qingfeng was stronger than him.
This situation immediately made Xie Liuyun realize. While he agreed with Sheng Qingfeng's opinion, he also blamed himself for being careless this time.
What I am missing is that I graduated with a major in science and engineering. Why didn’t I think about it based on the characteristics of this material?
Magnetic objects will definitely react with the geomagnetic attraction.
And such magnetic objects, as long as they are long in shape, can be used as compasses.
How could I forget such a simple truth and not think of it?
It seems that any time this inattention exists, some important clues will be missed.
Even if such clues are right in front of you, you will turn a blind eye to them, allowing you to watch the essence of the matter being found by your colleagues, and the truth being discovered by your colleagues.
This situation really made Xie Liuyun very uncomfortable.
Since returning to the Ministry of Defense and participating in training, I have never been so careless. Now that something like this has happened to me, this is extremely inappropriate.
What made Xie Liuyun feel even more uncomfortable was that the way Yong Ming looked at him just now did not reveal the slightest hint of blame, which made Xie Liuyun even more annoyed at his own stupidity.
Yong Ming is undoubtedly a man with a broad mind, and his magnanimity is a role model for everyone.
Xie Liuyun felt that he had just neglected to take earplugs seriously. Now it seems that this is by no means a simple personal safety protection equipment. The main reason is that he did not know enough.
By comparing Sheng Qingfeng's situation, Xie Liuyun realized that he had not adjusted all his attention to action. He immediately aroused vigilance in his heart and raised the level of self-monitoring psychological control.
Shang Baifeng does not understand what a "compass" is.
He had never even heard of the name of this "compass", let alone seen a physical "compass".
Because he has never traveled far alone since he was a child, so he has no need for a "compass" to help him travel.
Every time he went out, he always followed his father or the elders in the family, and never had to worry about anything on his own.
Moreover, every time they go, they are close to the city of Xi'an, where they are familiar with the roads. They do not need to use a "compass" to identify the direction and determine their orientation.
This is why he doesn't even know there is such a thing as a "compass" even at this age.
Now, Shang Baifeng really wanted to ask, what exactly is this "compass"?
But he didn't know who to ask?
After thinking about it for a while, I felt that this was not an important matter, so I simply didn't say anything.
After listening to Sheng Qingfeng's analysis, Huang Hanhan couldn't help but clapped his hands lightly and praised: "Qingniu, you are really amazing!
After you hold the earplugs and play with them for a while, you can guess that they can be used as a 'compass'.
I think what you said makes sense. The third function of this earplug should be like this.
Brother Ming, do you think what Qingniu said is correct?"
After finishing speaking, Huang Hanhan looked at Yong Ming eagerly, waiting for Yong Ming's statement.
After Yong Ming looked at Xie Liuyun, he looked at Sheng Qingfeng and said: "Qingniu, you are right, your analysis is correct.
The third function of this earplug is that it can be used as a 'compass'.
Judging from your consideration on this matter, Qing Niu, you are really thoughtful.
In this way, it saves me the need to explain this specifically.
Now, everyone should prepare themselves, we are going to start taking formal action against the 'Twelve Disha'."
