From the northern sky of Smoke Island, groups of tiny black dots in the distance congealed to a massive group, slowly moving inland.
The group of dots resembled flocks of black birds soaring against the blue sky, completely uniform, lacking differentiation.
Every single black dot was a fighter aircraft. Not regular aircraft, but strange pieces of machinery with odd shapes. From the bottom of their fuselages spouted two additional boat-like long boards, which betrayed their identity as a next-generation seaplane.
The aircraft flew past the airspace swiftly and, after a while, was trailed by a small plane.
Behind this aircraft following closely was a black hot air balloon with a black, rectangular wooden boat dangling below.
There were a group of men in black scattered in the boat. All of them were equipped with thick black leather shirts, goggles, hats and scarfs.
