He silently interpreted each word.
Having never encountered rules like these before, Lin An carefully pondered all the information provided by the System.
According to the System's explanation, Frequency Perception should be similar to Mental Strength detection.
It was merely detecting something more unusual.
"Detecting brainwave activity? The more accurately I obtain the frequency, the better the interference effect?"
It was not difficult to understand.
Lin An quickly realized what this effect was for.
All living intelligent beings had brainwaves. As early as the World War II era on Earth, the military had already studied brainwaves, attempting to use them as the basis for developing lie detectors and Mind Control devices.
Of course, with the level of human technology at the time, they had naturally failed. Only lie detectors were barely of any use.
"Brainwaves are fluctuations in the electrical signals produced when the brain is engaged in thought. As long as I can decipher the meaning of each signal, then in theory, I can 'see' what a person is thinking."
"Once I can detect them clearly, I can find flaws in their thoughts? Just like certain Illusion-type abilities, which first find weaknesses in the mind and then attack those weak points."
His gaze flickered, and Lin An subconsciously thought of the Illusion incident he had encountered in South Korea.
That Special Mutant, which was only Second Order, had "seen" the weakness deep within his thoughts and used it to create an Illusion to attack him.
Compared to the ability possessed by that Mutant, the ability contained in this Fifth Order rule was clearly far more advanced.
It directly detected brainwaves.
That was hardly any different from mind reading.
It was practically invincible in battle.
Of course, Lin An also understood that Frequency Perception should not be that absurd. Or
