Jake calmed his nerves down and looked around the cave. He was still concerned about the situation and wanted to make sure that there was no one other than him in there. His body had undergone a lot of stress. Not only had he spent a huge amount of points to gain strength, but the injuries were also severe.
He immediately activated the healing runes over his body and employed Drake's Breathing Method to instil energy inside it to help it heal. The runes were working in sync with healing runes. He could use the BOU points to heal back up, but recent uses revealed something.
While the ability granted him instant healing abilities, the healing was on the surface, and the deep scarring due to the impact taken wasn't healing at the same rate. They were slowly stacking up due to prolonged use of the ability. He was going to take this opportunity to heal all the injuries completely.
