Super Invincible Battleship

Yan Fei ordered a small drone online, never expecting that the drone would suddenly become his avatar.
Amazing, right? But what's even more incredible is that this drone avatar can actually upgrade, into a drone fighter jet, a heavy combat jet, a stealth bomber......
Are these powerful combat units really my avatars? Do they really expect me to take on the entire world?
Yan Fei is utterly bewildered!
