After a few hours, Sol slowly sat up.
His exhaustion wasn't due to him depleting his Internal Aether Energy, it came from him over-exerting his Willpower. And by the fact that his Willpower was connected to his soul, what was exhausted was his soul.
Thankfully, he had his Innate Dharma.
Normally, the only way for someone to recover from overexerting their souls was to take medicinal pills or simply rest. There were some Martial Arts Techniques that involved cultivating one's soul that could help as well.
However, each of these methods would take time. But Sol had his Innate Dharma that was more effective in healing his soul than any of these methods.
After sitting up, Sol decided to leave the cave and go outside.
When he was at the entrance, he heard Abdu saying behind him.
"You should take it easy. Remember I said anything involving your soul should be handled with caution."
