The following are my personal views.
Actually, the widespread choice of various civilizations to enhance the body rather than develop large-scale destructive weapons (such as Two-Dimensional Foil, energy weapons, etc.) as the core of combat power construction is not a loophole, but a reasonable evolutionary path based on effective use of resources.
Next, I will analyze from multiple angles why body enhancement is a better development direction in Monster World.
First reason: Individual evolution is more economical than weapon development.
In most science fiction settings, high-destructive weapons (such as the Star Destroyer Cannon, dimensional strikes) require massive resource consumption.
It's like after a bullet is fired, you have to load another bullet.
Some highly destructive weapons are even one-time consumables, and must be remanufactured after use, forming an endless resource black hole.
