From Prey to King

Damien White is betrayed on the day he is born and left in a dangerous forest. He has been reborn there as a white tiger cub, in the Realm of World Beasts, where strength settles everything. With nothing else left he wakes a power that lets him devour other creatures and take their strength for his own. Every time he uses it he moves up a level and past whatever limit he was at. From a cub that cannot defend itself he works upward. He takes in strength, gathers others who will fight alongside him, and goes through the beast territories against whatever is strongest in them. What he is doing it for is revenge on the ones who left him. Above him are the divine beasts at the top of the spirit realm, and as he gets close to them, things that had been keeping still start to move.
