With Wu Chu's demonstration, the others finally believed he really had been comprehending the art of thunder just now. It was only that a slight mishap had occurred in the process.
No one would believe that the thunder just now had been a gift from his master.
Of course, Wu Chu wouldn't tell them himself.
Two days later, Feng Yi and Di Kun each returned from Jade Capital Mountain with a floating mountain.
They wrapped the enormous floating mountains in their magic power and shrank them down until each was the size of a small hill, then carried them in their hands. They looked a bit like Small Mountain Seals.
"Do you know how to perfect a world where living beings can dwell?"
Faced with his two disciples' bewildered expressions as they shook their heads, Wu Chu had no choice but to take on the responsibility of a teacher. "Living beings need to breathe. What is it they breathe?"
"Spiritual energy!"
The two disciples replied with absolute certainty.
Wu Chu gave a light cough and shook his head. "That's right, but not entirely. You're already powerful cultivators in the Severing Corpses Realm. Analyze the components of the air around you, then try to trace where they come from."
A moment later, Di Kun said, "Besides spiritual energy, there seem to be quite a few other components in the air. Some are waste gases breathed out by living beings, and some are spiritual energy exhaled by plants. Among that spiritual energy, there are other components too..."
Wu Chu couldn't be bothered to teach them chemistry, so he said, "That's why a world needs to possess the most fundamental Great Dao Law: the Five Elements Great Dao Law. Plants need sunlight to breathe, and sunlight can be regarded as coming from fire.
