Harnessed Circumstances
If Martial Sages had too many senses that were too powerful for a paltry optical illusion to work, then the solution was simple.
Rui just needed to get rid of all those senses.
That was where his extraordinary hypnosis, further exponentially enhanced by the Gigabrain technique, came in. Ordinarily, the hypnosis of a Master would bounce off a Martial Sage like a beach ball would off of a steel wall.
However, in his current state with the Gigabrain technique, Rui might as well have been in an entirely higher Realm compared to the average Master.
The goal was simple.
Misdirect all her attention and consciousness to focus exclusively on visual sensory data, discarding all other forms of sensory input and awareness.
