Rex blinked, and the world changed.
Time was suspended; he tried blinking a few more times, hoping that somehow the world would return to normal, but it never did. His pupils dilated as his instincts immediately flared, expecting this to be an attack from an unknown entity.
Perhaps the one who had been messing with him all this time.
His reflex was deathly fast.
The very moment he saw time was halted, he used the System to scan the surroundings.
Whoever this entity was, he's extremely fast.
Back then, when he was within the Aurelius House' domain, Rontera, he also scanned the surroundings right when he snapped out of his daze. But he found nothing—he couldn't find the one who controlled the knife, and there was no trace left behind either.
Learning from that incident, he immediately scanned the surroundings.
He tried to react faster.
But he soon realized that it wasn't an enemy he was dealing with right now.
It wasn't the entity that controlled the knife.
