"A space cannon? I think we have it! Is it like an air compressor?" Gordon asked curiously.
Viclan said, "That's far from being called a space cannon! Yes, the air cannon has been invented. Its shooting range is mostly within a hundred meters, and 50m is the most effective range."
The air cannon was also a weapon, and compressing air wasn't rocket science.
Everyone knew it.
However, the air cannon was nowhere near as powerful as a space cannon.
"The space cannon our Patriarch mentioned is heavy ground-to-air equipment that doesn't require oxygen. As you know, air consists of more than just oxygen. A space cannon is more than enough to destroy our nearest satellite."
"What?"
"Is it that powerful?"
"By compressing air alone?"
Everyone was astonished, including some of the scientists.
