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!
