Alright so The lightning emperor definitely knew that Lucius had the power to control Abominations (and with it maybe understood he was the child of calamity). This might mean that the reason all children of calamity get picked up (by the lightning empire might I add as seen at the very start of this novel) is that the lightning emperor knows how powerfull children of calamity can become. Adding to this, I think it's reasonable to assume that the lightning emperor will be finding out, maybe even already knows, that Shang is the child of calamity and he will train him with Abomination techniques. Thanks for the chap!
