That smile was terrifying from Aiden's point of view. It was as if Lucius had already anticipated everything.
However, Aiden didn't give up on his strike as he had activated his [Shadow Strike] which meant that his attack was supposed to be invisible. However, Aiden didn't know why, but he could already tell that his attack was bound to fail.
He just had a feeling, and it seemed that he wasn't wrong because as soon as his dagger arrived close to his neck, Lucius literally disappeared, just like what happened when he had first tried to attack him.
It was as if, he had some sort of defense for deadly attacks or something similar that made him disappear from Aiden's point of view.
Was it a technique or a skill?
Aiden wasn't sure, but he did know that it was ridiculously overpowered.
Then, as Lucius appeared behind Aiden, he didn't lose any time as he immediately went in for a strike toward Li Feng's heart.
