Sifangtianyu

The iron filings caused by the clash of steel, the raging flames from the muzzle—— The bullet chains and fire that cut across the sky across the position scattered the birds and ships, leaving only the armor invincible. Guns, tanks, spaceships... On a battlefield beyond the reach of conventional tactics, involving broken steel and iron bones, beautiful and agile high-mobility arts, and deep skills locked in a life-and-death struggle, only mechas can defeat mechas. This is the only iron rule.
