That wasn't only why these monsters were going to be scary! The little details she missed made all the difference! Precisely speaking, it was all related to the high-grade and concentrated spirit power filling this special area!
William didn't come here for no reason! He didn't build the grand spirit concentration formation or the smaller versions of it for no reason!
What would really turn these monsters into unstoppable killing machines was the cores that he made. They were left inside the smaller spirit concentration formations for more than a day, absorbing and storing a scary amount of high-grade spirit power.
These cores would be the engine for these monsters, the heart that would pump higher-grade spirit power and activate these behemoths. Even if William would provide his spirit power for these monsters to function, even if he would use the help of other masters in different battlefields to operate these, the core still mattered the most!
