The Profound Old Ghost curled his lip nonchalantly. "What's the problem?"
Mu Chen pondered for a moment, then said uncertainly, "Master, I didn't stop because I ran into a problem with rebuilding my Dantian. It's my Spiritual Power."
The Profound Old Ghost was taken aback. "Spiritual Power? What's wrong with your Spiritual Power?" As he spoke, his figure appeared beside Mu Chen.
Mu Chen shook his head. "I don't know either. Two days ago, I suddenly felt like my Spiritual Power hit a bottleneck."
The Profound Old Ghost paused, then burst out laughing. "You silly boy, this is a good thing! It means your Spiritual Power is about to break through to the Leaving Realm."
"The Leaving Realm?"
The Profound Old Ghost explained patiently, "Spiritual Power and Primordial Power are both forms of energy. There's Energy Soul Refining and Primordial Power Forging Soul. Since Primordial Power Cultivation has levels, Spiritual Power naturally does as well."
