The gun that Lulu is using is a riffle with two meter and a half long barrel, and it uses magic as the explosive instead of explosive powder, shooting substance bullets. During the shooting, the repulsive force occurs on the whole gun, and bullet doesn't touch the inside of the gun barrel. I had a very hard time making this circuit mold, so I instructed her not to use the gun as a club. The bullet only travels at about half of the speed of sound, but since it's a big 20 millimeters caliber bullet, its destructive power is extraordinary.

>tạm hiểu: lulu dùng súng trường, bắn đạn 20 mili với nữa tốc độ âm thanh =))
