He was physically tired.
He was wounded. Bruised. Cut.
He was mentally exhausted.
Yet he pulled himself together when he felt yet another surge of peril with Primordial Instinct.
WHOOSH
The assassin was stealthy.
Rui could feel the misdirection even as he approached.
Unfortunately for the assassin, Rui's mind was extremely difficult to misdirect. On top of that, his senses were extremely powerful. On top of that, Riemannian Echo was indirect sensing.
He was so resistant to being misdirected that Kane had stopped bothering to use Void Step when sparring against Rui. It was simply useless. At this point, he doubted whether any misdirection in the Senior Realm could even affect him.
Unfortunately for the assassin, the reports that the M had given them did not entirely capture how resistant to misdirection Rui was.
That was why he was waiting.
