Camilla personally guided Michael, walking through a narrow passage.
Michael could perceive that as they were advancing, the concentration of Spiritual Energy in the air was gradually increasing.
Generally speaking, encountering such a situation meant that there was either a spiritual mine up ahead or some precious natural treasures.

Michael was surprised.
If this was before he headed to Penglai Island, he would definitely be ecstatic.
But for the current him, even high-quality spiritual stones did not have much effect. Knowing the situation from Camilla's introduction earlier, he seemed very calm.
