"What is this Earth Principle?" Su Yang asked curiously.
"The Earth Principle is similar to the Heavenly Dao; it is a rule from the birth of the universe," said the Emperor Slave. "It embodies regulations without life or consciousness!"
"So we must also abide by the Earth Principle to absorb Earth-level Spiritual Energy?" Su Yang questioned.
"Exactly!" The Emperor Slave nodded. "If one doesn't follow the Earth Principle, there's no way to absorb Earth-level Spiritual Energy."
"Then... what's the difference from the Guardian God?" Su Yang was suddenly disappointed: "Since it's necessary to follow the Earth Principle to absorb Earth-level Spiritual Energy, why not just follow the Heavenly Dao from the start instead of wasting energy fighting the Guardian God?"
"Although this is what it seems, wouldn't you at least want to see which rule suits you before deciding which to follow?" The Emperor Slave replied.
"Is there any difference?" Su Yang was puzzled.
