There were only a few ways genjutsu worked.
One was to affect the target's senses, severely distorting the information they received and thereby impairing their judgment.
Another was to act directly on their mental energy, forcibly disrupting their ability to think and judge.
Beyond those, some genjutsu inherited through kekkei genkai were rather more extraordinary.
Genjutsu such as Tsukuyomi and Infinite Tsukuyomi, for instance, altered the entire surrounding environment, leaving the target unable to make accurate judgments.
In short, the ultimate purpose of genjutsu was to disrupt the target's mind and thereby impair their judgment.
The genjutsu Ye Chen was currently facing was merely an ordinary one that affected his sensory perceptions.
The illusions that kept appearing were deceiving Ye Chen's senses, attempting to impair his judgment.
Yet although Ye Chen's senses were restricted, his judgment remained entirely unaffected.
This was all thanks to the system's "target lock" function, which let Ye Chen firmly believe, deep down, that all these realistic sensations were nothing but illusions.
Breaking such simple genjutsu was easy, too.
He only needed to shut off his own senses.
No looking, no listening, no smelling, no speaking, no guessing.
With his senses shut off, the genjutsu would lose its influence, which amounted to breaking it.
With the system guiding him, shutting off his senses would not affect Ye Chen's speed of advance.
Yet Ye Chen did not shut off his senses.
Whenever he encountered novel ninjutsu, his instinct was to experience it for himself.
If he could successfully "pick up the technique," that would be best of all.
The genjutsu before him was not complicated, either. After experiencing it firsthand for just a short while, Ye Chen had already gained some insights.
His speed did not diminish, and the illusions he crashed into along the way grew
