From the moment the first blow landed on Kent's body, he knew he was outmatched.
However, while he could merely ask Gaia to lock Lord Forsaken down and seal the place so that later, when he had the required strength, he would come back to face him, Kent's nature immediately rejected the idea of retreating.
If anything, he felt like going into a life-and-death battle.
So he stayed, and for the 40 seconds they fought, he was outmatched in both speed and attack power.
However, that was the main reason Kent chose to fight in the first place.
When he fought his perfect clone back in the sect, it was merely a battle where they were all using the same skills and techniques.
He lost in the end, but he didn't feel that danger, knowing the enemy would be making a move he had never seen or used before.
That adrenaline, the rush in knowing the next second he would be stabbed through the heart or beheaded, that danger, he wanted to feel it, and thus Kent was locked in this battle.
