"I don't know either."
The Hall Master of Wuhun, shaking his head in grief, said, "We dare not inquire, we only know that Elder Taiji is in the Infinite Celestial Tomb."
"That's the truth," Gu Chenfeng said with a faint smile. "Here's another question: Typically, no force would station an Immortal Venerable or Immortal Emperor to guard a mine. Be honest with me, what treasure is in the mine?"
"The Seven-Colored Immortal Spirit Stones," answered the Hall Master of Wuhun.
"Seven-Colored Immortal Spirit Stones!" Kuang Yunshan exclaimed, his eyes widening in astonishment.
"It really is the Seven-Colored Immortal Spirit Stone!" Ye Jiuchong said with elation, "I can't believe I guessed it right."
Gu Chenfeng asked again, "The Seven-Colored Immortal Spirit Stone is nurtured by heaven and earth, rare and hard to find. Why does Xu Wu have you guard it and not take it away directly?"
