First, though firearms are powerful, Void Things have all kinds of methods: virtualized spirit bodies, flying escapes, tearing through the void, death replacement, clones... an endless array of incomprehensible tactics. They're not stupid either—if they sense danger, they'll do everything they can to preserve their lives.
Second, the explosive power of firearms is too great. The instant high temperatures and destructive force—even if a Void Thing is hit, it will be blown out of existence. So how do we collect the required materials for scientific research and crafting, to improve the quality of Void Blades?
Right now, in the Void Realm, we can use firearms—even nukes—without restraint. But if a Void Thing slips into a crowded city in our world, we still mostly need to deploy Martial Arts Experts to avoid causing greater secondary damage from firearms.
