It seems that this oxygen mask is a backup device for the diving suit, which is very thoughtful. However, the matching eyes on the oxygen mask are not night vision goggles.
Feng Yuchen took a brief second look, then immediately raised his gun and made a standard military 'ready to fight' gesture.
Lei Fan and several soldiers, infected by Feng Yuchen's serious attitude, also felt the danger. They picked up their weapons one after another and focused their attention. Only then did they realize that the sea water around them was slowly undulating, and the undulating
The frequency is gradually increasing.
While Feng Yuchen was paying attention to the movements in the depths of the sea around him, he put his fingers to his lips, shook his head slightly, and pointed at his ears to make a death gesture. His meaning was very clear: don't speak, otherwise the target will be exposed.
If you do, you will die.
His series of actions were seen by the soldiers as a reminder to them to be more vigilant and not to speak casually, lest they expose their targets and fall into the trap of 'hunters'.
Only Lei Fan understood the pun intended by the boss. Exposing the target may be in danger of death. This is true, but the most serious thing is that the ears.
He was referring to the ears, not the temples.
The specifications of military diving suits are the same. The sea lion uses communication facilities, so when the headset is activated, it is also attacked by electronics. The headset turns into a miniature bomb, almost killing the sea lion on the spot.
In other words, the diving helmets worn on several people's heads and the headsets placed in their ears are equivalent to mini bombs. If they do not speak or make any sound, the headset connected to the microphone will not activate.
When activated, the other party will naturally be unable to detect their location, cannot remotely control them, and cannot conduct electronic attacks.
However, if one of them tries to contact his companions through the communication device installed in the diving helmet, he will be exposed not only himself, but also the companions being called.
At this moment, except for the sea lion captain, one person spoke, and the other five people could hear it.
Once they expose their target, they will become the next sea lion captain.
This is undoubtedly a bomb buried in the body, which may explode at any time and kill oneself.
To get rid of this threat, they have to take off their diving helmets.
Use an oxygen mask instead of a diving helmet like a sea lion to avoid the risk of explosion caused by exposing the target.
However, the vertical distance between them and the sea is at least three to four kilometers, and it is late at night. It is pitch dark here. If you take off the diving helmet, it is equivalent to taking off the night vision goggles. It is equivalent to blindfolding and turning into a human.
blind.
When the surrounding water waves are getting more and more violent and danger is approaching quickly, covering your eyes is undoubtedly suicide.
[Go up!]
After a few people were quiet for a moment, Feng Yuchen made an upward gesture, indicating that everyone should take off the gravity buckles and go out to the sea first.
Lei Fan and several soldiers all moved, and only then did they notice something strange about the sea lion. The sea lion did not have the night vision goggles in the diving helmet, which was equivalent to being blindfolded at most. Normally, this had no effect on the sea lion's hands and feet, but he was responsible for taking care of it.
Lei Lei, a sea lion, found that the sea lion was "dumb" and seemed to have no behavioral consciousness.
Lei Lei subconsciously stopped and approached the sea lion captain's face, wanting to see what happened to the sea lion.
Through the diving helmet and goggles, Lei Lei vaguely saw that the sea lion captain's eyes seemed to have turned pale. He was shocked and quickly shouted stop~~~
