Mutant
After killing the last few goblins, Nial picked up the origin crystals that had dropped before he distanced himself from the crime scene.
Once he reached a certain distance, he slumped to the ground, and took a few deep breaths.
While actively replenishing his mana, Nial simply used an origin crystal to hasten up the process, not bothering about the hefty sum of 30$ he paid for the crystal that was pulverized within seconds.
It didn't take long before he was reinvigorated, and his mana core was filled to the brim, but instead of clashing against dozens of goblin groups, Nial wanted to do something different.
However, on second thought, releasing his pent-up frustration would probably be the best. At least for now.
His body was aching lightly, but by straining his muscles they would be tempered and trained for such rigorous physical activities.
