A tall, bright rune hovered before Khan's chest, absorbing mana from the world and sending it inside his body. The night had fallen, but the symbol glowed with uncanny, dangerous light, illuminating the destroyed and leveled mountain area.
Faint trails of smoke rose from Khan's torso. His flesh was tough beyond reason, but that prolonged and forceful mana absorption had pushed it to its limits. Its friction force had started to erode Khan's skin, burning and scarring it with red marks.
The process obviously hurt, and the pain increased with each passing second, but Khan barely felt it. Far stronger emotions afflicted his mind, making him ignore that torturous suffering and push his training session further.
Khan had always been good with pain. Yet, he had stopped going overboard in the past years, most times, at least. Khan didn't mind being hurt but had other reasons to hold back.
