Angel was startled for a moment, not immediately grasping Sanders' intention.
It was only when Sanders launched an unreserved attack on him that Angel realized what Sanders was planning... What kind of test was this for assessing his training progress? It was essentially forcing him to make a move!
Once he acted, it would not be easy for him to hide his creation of spells.
"So ruthless!" Angel complained inwardly, but faced with Sanders' attack, he had no choice but to respond, silently thinking to himself: He couldn't fall for Sanders' cunning plan.
That was easier said than done, though.
Sanders' attack was not a one-off effort, but rather a persistent assault tailored to Angel, blocking all of Angel's techniques.
And Sanders didn't take Angel's physical strength seriously, because once he used illusion techniques, Angel couldn't even determine his whereabouts.
He could only passively react like a target.
