Defending the building
Qusay's original plan was to form connections and deep bonds with the currently weak and easy-to-control peers of the same power level who had great potential to surpass him in the future. He would gather them into a group and offer them a level of protection as the strongest one in the group. With this arrangement, when those people matured and grew stronger, they would have a sense of gratitude and he would be able to form a network of powerful allies in the long run.
Who would have thought that Kane's power level would explosively increase in almost an instant? The gap between them widened so much that their roles would reverse. Kane was now the one protecting them and he was even going to provide resources to the group.
