However, her expression gradually changed as Cao Zhen kept picking up various materials, showing no sign of stopping whatsoever.
She couldn't help but speak up, "Peak Master Cao, just how many formation maps are you planning to refine?"
"Six," Cao Zhen replied, looking up with a flash of his white teeth, "Old lady, don't worry. If you feel that one more formation map is not enough, I can make another one later."
"It's not about making a few more formation maps. It's these materials you're using. What kind of formation map are you refining that requires so many materials?" Ai Yunqi said, watching Cao Zhen still constantly picking up materials, feeling that the Immortal Soldier Workshop was not far from closing down.
Is this really for refining formation maps? This is more material than what is used for refining divine weapons.
Even for an extraordinary formation map, it shouldn't require this many materials, right?
