Hearing Lu Wen's answer, Xu Fei sucked in a deep breath, "Who was that person?"
He felt unease within his heart.
Lu Wen, however, shook his head, "I do not know who that person was. His voice seemed to have been disguised, and I was unable to distinguish it. However, his cultivation base was definitely very high."
Hearing Lu Wen's reply, Xu Fei's heart could not relax.
While Lu Wen had not revealed a shocking name, someone who was able to freely enter and exit Lu Wen's seclusion grounds must be quite an important person.
His Master, Fang Zhun, could enter and exit this place freely, but if nothing special occurred, Fang Zhun would generally not do so.
Other than Fang Zhun, other Essence Talisman Martial Grandmaster experts were also able to conceal their presence and enter this place without leaving behind any traces at all.
