Abomination emperors don't hate mana. If Shang can make his mind like an abomination emperor, even if he doesn't care about the concepts, he can probably learn all of them.
He needs more grounding experiences.Otherwise he will be slapped as soon as he is confronted with something he is not familiar with or that counters him. Being powerfull and confident is cool, but being cocky and underestimating any enemy is just begging to be killed.
Well that is going to be hard to properly absorb when he needs to power up. wonder if he will go back to having a proper human form in the future. May you fail at the last step Young Master Shang.
