Chapter 515 Exorblast Level Ten

• Sebastian had been confined in the mountain chamber for weeks. To keep his spirits up, Isabella and Elvira visited him every evening to chat. Their company warmed his heart, and in return, Sebastian guided them in their training.
• Ten days passed; Sebastian had already mastered the fourth level. No one would believe it if he said it out loud.
• "The first level of Exorblast hardly uses any energy, yet it delivers massive force. The second is similar. But once you hit the third and fourth levels, the true energy cost jumps. With the true energy I've built up, I can probably use it around a thousand times before I'm completely drained," Sebastian explained.
