The combat personnel of the operation type with a fire gun, which already exists in reality, even though optimized within the Eye World, wouldn't turn a fire gun into a star destroying cannon.
A fire gun remains a fire gun; it just exhibits power fluctuations based on the individual's mental strength...
Simply put, it's like those fixed damage roles in games, the mental power to manifest weapons of operation type is akin to skills with fixed damage values, capable of delivering fixed damage even with an utterly blank slate.
Of course, this fixed damage is subject to enhancement by the individual's strength or intelligence attribute, it won't fall behind just because the user himself is overly powerful.
Such weapons are more suitable for those whose individual powers are not strong, because even the weakest can still deal significant damage through these weapons.
