When hit by the light of the "energy enhancement device", the power will be different from that of ordinary people. Skyforce leader Tianlong selected four members to undergo the experiment. On the way, they were attacked by the dimensional war group "Bairavu". The explosion caused the light on the device to shoot towards the earth and hit four earthlings by mistake. So Tianlong immediately went to the earth to find them and formed the "Birdman Team" to fight the enemy. This game is the first precedent that soldiers can fly.
