A World Without Spiritual Energy!

"It's impossible!"

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? How can they boast destructive force without training?"

"With oil, coal, gunpowder, electromagnetic energy, and nuclear energy!" Li Yao replied solemnly. "Of course, when the interference is too severe, it is hard to say whether or not electromagnetic energy and the nuclear energy are applicable, but the former three are guaranteed to be usable!"

"Oil, coal, and gunpowder?" The theorist of spiritual energy was dazed for a moment before he observed with a weird expression, "That is the most barren source of energy. The energy contained in oil is less than one hundredth of that contained in a crystal of the same volume. What can it do?"
