One Golden Trait Per Level: I Become the Beast Tamer King

Lu Ze's soul transmigrates to a world ravaged by disaster, where he unexpectedly obtains the Supreme System. Every time he spends money, he gets a multiple of it back, and he can even exchange it for legendary gold-rank entries. You say a poor nobody like me doesn't deserve to be a beast tamer? Ever seen a gold card worth hundreds of millions pulled out on a whim? You say my contracted beasts are too weak to team up with? Perfect. I'll slaughter my way through the Abyss alone. As Lu Ze races down the road of cheating his way to victory, he soon discovers just how satisfying it is to have cheats! Watch as Lu Ze cheats his way forward, gathers countless beasts to build a monster army, spends a fortune to construct an impregnable fortress, and leads humanity in its resistance against the Abyss! No money, no beast taming? I've got infinite cashback and riches to burn!
