Alex did not lack an offensive technique, whether it be for his Body, Qi, or Soul. His offensive strength was the highest it could possibly be.
He also didn't see the need for any movement techniques as he could just teleport around instead of running.
In terms of defense, there was a significant lack compared to offense, but even then Alex thought there was something else he needed more so than defense.
He needed an escape technique.
That was the technique Alex realized that he needed more so than anything else. He especially needed one that worked even when he was trapped and unable to use teleportation.
The next technique Alex needed was one for cultivation. He had the Five Yang Divine Path technique for Qi cultivation, so that was more than enough for now. As for his Body, there was the Mountain Crushing artifact.
Blood aura could only be improved through absorbing blood and Sword Intent could only be improved through training.
