Moonlight Butterfly could definitely be considered a concept-class weapon. However, this kind of weapon did not target a specific objective, but an entire civilization. How could a weapon capable of destroying a civilization not be considered concept-class?
What Xiao Ran needed, however, was a truly destructive weapon capable of targeting specific objectives, such as a Native Species BOSS.
"Concept-class..." Luo stroked his chin and nodded lightly. "I roughly understand what you mean. Those three words are indeed fitting as a summary, but for us right now, I think Rule-class would be a better term. Weapons capable of guaranteed kills or absolute hits, carrying special effects, and effectively inflicting damage on enemies with Rule-class or concept-class abilities."
"Time Weapons, Space Weapons, Gravity Weapons—weapons that alter physical laws rather than merely making use of them—should all fall within the scope of Rule Weapons. In that case, we actually do have concept-class weapons of the kind you want. The MACORSS Cannon used by warships counts as one, and the Black Hole Cannon barely qualifies as well. Your new unit is equipped with both. In addition, the Dimension Devourer and MDE warheads also fall within this category."
Shirakawa Shuu's voice rang out at that moment. "Although the Black Hole Cannon has reached the Rule-class level you seek, the true Rule-class weapon is Gransam's Retraction Cannon. We can consider upgrading and modifying the weapon again. As for Space Weapons, we already possess them. At present, they can only tear space apart and create fractures, but we should be able to achieve the level of truly ripping space apart. Finally, Time Weapons are not something we are incapable of creating."
Luo considered this. "You mean the Time Flow Engine? We have had that technology for quite a while, but the engine has not been fully completed.
