He concealed their auras with [Severing Past and Present, Leaving or Staying].
Zhang Yuan and Xie Jingxin quietly left the reception palace, rounded several corners, and stopped in a secluded nook, releasing divine sense to probe the entire Demon King Palace.
The [Yin Net Tranquil-Illumination Palace] was enormous. Its visible exterior alone was ten times the size of Roselight Capital, and it seemingly also contained spatial formation arts, making its actual area even larger than it appeared. Finding the place where Heavenly Materials and Earthly Treasures were stored within the [Yin Net Tranquil-Illumination Palace] would certainly be no easy task.
Zhang Yuan spread out his Celestial Person divine sense, trying to detect where the Heavenly Materials and Earthly Treasures were within the Demon King Palace. Yet as his divine sense expanded, it sank into the palace's depths like a stone sinking into the sea.
This isn't good. There are even formation arts that block divine sense probes. The [Yin Net Tranquil-Illumination Palace] really came prepared. Could a Celestial Person of the sha ingestion gang devoration path have visited before, putting the [Yin Net Tranquil-Illumination Palace] on guard? If that's true, Celestial Persons of the Dust-Dyed Realm really are born evil!
Feeling somewhat helpless at the thought, Zhang Yuan could only retract his outspread divine sense and sink into contemplation.
Now that he couldn't sense where the Heavenly Materials and Earthly Treasures were, only the clumsy method remained.
"What's wrong?"
Xie Jingxin had been following behind Zhang Yuan all along. Seeing him frown as though something had stumped him, she asked.
Zhang Yuan said, "We certainly can't leave the [Yin Net Tranquil-Illumination Palace] empty-handed after coming all this way. I wanted to find its treasury, but unfortunately, I couldn't sense it. We'll have to take things one step at a time."
