With a 20-millimeter caliber, that must be classified as a cannon, not a gun.
Gao Yang looked at Gao Yuan with a face full of hope and asked, "Can 20 millimeters get the job done? Have you tried it?"
Gao Yuan thought for a moment and said, "Well, I really don't know if it will work, but it seems we've tried shooting Armored Beasts with a Shenzhou-produced 25mm Anti-Aircraft Gun. Hmm, there were a lot of ricocheted rounds, and the penetration effect wasn't very good, but after the battle upon examination, we found that the 25mm anti-aircraft cannon shells indeed left penetrating wounds on the Armored Beasts."
Gao Yang's eyes shone, and he smacked his hands together, exclaiming, "That's it! Exactly!"
