Chapter 289: Masteries increased

Somehow, he was able to triumph against a Specialist-level Canzer using only his wits and his mutations.

Can I upgrade my mastery?

After all, he won a battle using only his Angel Wings and nothing more. It should be enough of a victory for him to increase his mastery.

He looked down at his Soul System and focused on the white Angel Wings floating in the darkness of the space.

He commanded a few lines of blue wisps in the collection of experience in his Soul System and moved them over to the Angel Wings.

The blue wisps revolved around the Angel Wings.

And as he concentrated, his internal body heat allowed the blue wisps to melt into a liquid. And once it had turned into this state, the Angel Wing mutation was able to absorb them into its very DNA.
