Superpowers?
Rising to the top in a single step was unworthy of one's virtue. Some 17-or 18-year-old youths suddenly became moon darkness or even sun glory. One person could fight against a thousand, and killing people was so simple and easy. With this sudden power, would superhumans be willing to advance step by step like martial masters?
No, they wanted to overthrow it!
They had to rebuild their own kingdom!
This was the current superpower realm and the current world.
The ghost-faced Martial Master was actually disdainful of supers who suddenly gained power, but reality was cruel. No matter how disdainful he was, he had to work for the supers!
So what if he was unwilling?
