The normal evolution path of Nirvana is the Thunder Ant King, with a quality that can reach Elite Level Middle Grade.
However, the Thunder Ant King is still a Strong Attack Guardian Beast, which does not meet Chu Chen's requirements.
As for other evolution paths, there are only four kinds, three of which are strong attack types, and only one is defensive, with an extremely low success rate, and failure might even lead to the death of the Guardian Beast.
Chu Chen naturally had no interest in these evolution paths.
This situation is quite normal, as Thunder Ants are just Ordinary Level Upper Grade Guardian Beasts with low cultivation value, so few breeders waste time on them.
Currently, he can only pin his hopes on the Slaughter Atlas and that unknown Evolution Formula.
At present, his Slaughter Value is as high as over three thousand, which should be enough to exchange for an Evolution Formula.
