A Nascent Soul Stage Cultivator who was adept at theories of spiritual energy could not hold himself any longer and rose up. "Fellow Cultivator Li, spiritual energy is the most magnificent force in the universe. What can you empower yourself with if not spiritual energy? How can ordinary people train themselves?
