No One Knows Magic Better Than Me

Shen Lang traveled through time and came to a big world where swords and magic, kingdoms, knights, orcs, dragons, and elves were intertwined. However, after waiting for a long time, he found that what he had obtained was an 'arms factory system'! Holding the 'Desert Eagle' redeemed by the system, Shen Lang was confused for a while when the children on the side asked what it was. Or, let's just say this, is it magic? Tanks take down behemoths, airplanes take down giant dragons. After all, they are all long-range attacks. Besides, no one here knows what this thing is.
