Ray looked at the red panel and made an almost instant decision: to advance the skill.
[Genetic Synchronisation (Awakening IV)] - [Genetic Synchronisation (Awakening V)]
Immediately, Ray felt a large chunk of his mental energy drain from his body.
"Hmm?" He frowned and checked the system.
"Eh, what?"
Ray had advanced the skill without even looking, and now he realised he had lost a hundred thousand mutation energy.
When he checked the skill, it could no longer be advanced. This realisation hit him hard.
"I can't fully upgrade my S-class skill," Ray muttered with a bitter smile.
But this wasn't a problem for Ray. All he needed to do was hunt more undead, which were plentiful after the next wave of mutational energy hit, mutation energy became incredibly dense.
The undead became even more abundant.
Although it took some effort to accumulate mutation energy, Ray could still do it with ease, so he wasn't too worried.
