"Whether it's spirit stones or treasures imbued with spiritual energy for soul suppression, they're not eternal. Use them too harshly and they'll lose their effectiveness.

"I don't know either. When I'm cultivating, I feel an immense demand for spiritual energy, and spirit stones alone aren't enough," Li Xin was somewhat distressed. "In the beginning, it was fine, but after opening up my meridians, it wasn't enough, and I could use dozens of middle-grade spirit stones at a time."
