At first, Joshua was skeptical of Erice's words, but when Erice said this, Joshua was instantly stunned on the spot.
"How... how did you know about this?"
Seeing Joshua's reaction, Erice knew that his guess was most likely correct.
"Joshua, haven't you seen any information about the Secret Origin Energy in the Windsor family's ancient books?"

"Secret Origin Energy belongs to the martial world. Yes! It is indeed the essence of heaven and earth, but it still exists in the air.
"Then, aren't you curious about why ordinary people can't become martial artists after breathing the air so many times in their lives?
"I'm afraid you've made a fatal mistake about the Secret Origin Energy.
"And this mistake may be what Kenna wants to see.
"It's not that Secret Origin Energy makes people become martial artists, but that people can only use it after they become martial artists!"
