Weapons of a Level-3 Civilization (1)

[Light Needle (Level 3): Accelerate one gram of 'needle point' to 99.999999% of the speed of light. Using the mass enhancement effect, it generates a collision energy of 139.5 billion trillion megajoules upon impact with any mass. Prestige required for exchange: 500.]

Zhao Yu read the description of the weapon on the exchange list, scratching his head, somewhat puzzled.

He understood each word in the description, but when combined, it all became incomprehensible. The last sentence, which mentioned producing 139.5 billion trillion megajoules of collision energy, left him unsure of the true power of this weapon.

All he knew was that this light needle was a weapon available to level 3 civilizations.

Fortunately, he could ask others about what he didn't understand.

Zhao Yu was about to ask Colonel Chu what a joule was, but then he paused.

Asking so abruptly might make explaining the origin of the weapon tricky.
