Unknown to Alex, his mind had slowly become battle-crazed.
Not that he wasn't aware of this desire to fight some more, even to fight those that he might have not been able to defeat, but the fact that his meridian points still hadn't shown any sign of reaching their limits made him more confident that he could take on some people that were stronger than he was.
Fighting above one's cultivation, both in the 3 plain realms and also here in Omega, such a feat is something that can only be done by a few. Those who are well prepared, those who are smart enough, those who are well equipped, and then those who are strong and talented enough to achieve such.
