After that whistle through the air rang out, a figure slightly larger than the Black-Grade Mecha from before appeared in everyone's sight.
In this era, besides Battle Armor, Mecha, warships, and soul-guided armored vehicles, there was another new type of weapon: Fighter Aircraft.

The only Fighter Aircraft designs Huo Yuhao had seen so far were the Star Luo Empire's experimental aircraft and some photographs he
