After becoming a fourth-circle wizard and a Greater Demon, Charles felt quite good about himself.
In the time since the battle ended, Charles had been continuously analyzing the complete Flame Rule he had purchased from Wu Duo Duo Mall.
Although this rule had already entered Charles's soul and he could wield its power, he could not make full use of it.
But after spending this time studying and analyzing the rule, Charles was able to unleash even greater power with it.
After the great battle, Charles had also obtained the Heart Core of a devil baron.
He could sense that this Heart Core likewise contained one or two complete rules.
Holding the devil's core, Charles thought, Demons and devils are natural enemies.
If it were an ordinary demon that obtained this core, it would probably swallow the Heart Core directly to strengthen itself.
But swallowing it outright would be far too wasteful. There is no way a demon could completely digest the rules within this Heart Core just by swallowing it.
At least most of its power would be wasted. It would be fortunate to retain even half a complete rule in the end, and filling in the missing portions later would likely require an enormous amount of time.
