"What is the Ancient Yinduo Spirit?"
"A kind of spell life formed from magic echoes, energy particles, and rune fragments in specific environments."
Sigel paused and added, "Ancient Yinduo is the name of the wizard faction that occupied the Silent Corridor back in the day, a school of ancient sound magic comparable to Spirit Lake.
Yet, overnight, it suffered a catastrophic disaster, and not a single wizard from the entire faction survived..."
"What kind of power could destroy a strong faction comparable to Spirit Lake overnight?"
Ronan was slightly moved.
Sigel appeared much calmer. "Curses, strong enemies... who knows."
He stopped communicating with Ronan's consciousness and walked forward.
