For the time being, he needed to focus on the two universes that they would engage in battle.
If it was just destroying them, it was rather easy and he could do it without even leaving his home, but that was not what he wanted.
Destruction has always been easier than creation, and it was fun as well.
Just introduce a zombie virus and the body cultivators would eat themselves. It was that simple.
As for the soul cultivators, that was a little difficult but all he had to do was create a gate to the underworld.
All sorts of creatures would crawl out to enjoy their juicy souls. Such pure soul energy made him drool, the underworld creatures would go into a frenzy for such a feast.
But that was not his objective.
He had to try and conquer these places and would only consider doing all this as a last resort.
If he could help it, he wanted to incorporate all the nine systems and it was the only way he saw to mastering null.
