Reincarnated as a walking lizard: game of thrones

A guy died and reincarnated as a raptor and there will be a system but it's not like a gamer or these kind no it is like the world devouring serpent, basically he can get points by eating living things and he can upgrade his body like improving speed or fang and etc........ hope you enjoy it. Ps: If there is any problem please comment so I can hopefully deal with it.
