Shang was tempted to delete that part of his soul.
But after a couple of seconds, he decided against it.
'Deleting something is different from changing something. I am not entirely certain how this part of my mind dictates my actions. I should wait.'
Shang continued experimenting on his mind and soul for another thousand years.
By now, Shang had gained a scarily deep mastery over his own soul, and his tests had almost all been successful.
The only problem was that Shang still couldn't fix the problem with Entropy's inherent dislike for Mana.
'There's no way around this. If I want to change my body, I need to change my soul, and changing my soul will change my mind and personality,' Shang thought.
