Yan Fei had not anticipated that just as he had returned to the ground, before he could take his next action, he was met with a ferocious attack from the US Air Force in the sky. However, the drone, already prepared for combat, merely launched a simple strike and took down two US F-15 Fighters.

Behind the early warning aircraft, two colossal C-5 Transport Aircraft were flying slowly.
