Gaven is not a dedicated Sacrificer like Katherine who serves solely for the expansion of the Goddess of Strategy's faith.
Rather, he integrates the expansion of his faith into his own development, as with this Conqueror Army, seizing the initiative to strike a deadly blow to his enemies and reaping ample benefits before anything else.
It's not just about developing for the sake of faith expansion, but using faith expansion to serve his own development, complementing each other for a truly comprehensive binding and a win-win situation.
"Since you already have a meticulous plan, then leave everything to you." The Goddess of Strategy decides not to interfere with Gaven's plan.
Because when she gets involved, the plan becomes fixed, and she can foresee the outcome at a glance.
