Murder Weapon in the Mortal World!

When they saw Meng Chao and the heavy metal murder weapon in the mortal world, everyone sucked in sharp breaths. 

"Th-That Type 45 AA machine gun's liquid absorber is damaged," someone stuttered. 

Usually, a muzzle with a diameter of 20mm was the dividing line between anti-aircraft machine guns and anti-aircraft guns. 

Guns with muzzles of more than 20mm in diameter were already artillery guns. 

This anti-aircraft machine gun had a diameter of 19.5mm and was a gun with the strongest power developed over the course of the past half a century by the Red Dragon Army. Not only could it be used against targets in the air, even if it was used to shoot in a straight, horizontal line, it could still reduce heavy-armored monsters into shreds, which was something the army often did. 

However, the price for this terrifying muzzle and fierce attack power were high recoil and vibration.
