Wei Shilin revealed the answer: "Many superpower users from the Fifth War Zone purposely came to check near Crow's Nest, but none could sense traces of supernatural power."
According to the theory in the "Secret Scripture," the Super Spiritual Power of the Primordial world is everywhere, and the entire world is an endless Super Spiritual Ocean.
Casting superpowers will disturb the Super Spiritual Power, thereby creating ripples in the Super Spiritual Power.
The latter is known as "traces of supernatural power."
Li Yuhang exclaimed with disbelief: "But the spruce wouldn't grow wildly without reason, would it?"
Wei Shilin laughed: "Of course it wouldn't grow without reason."
He paused, then said, "The key issue is, this is obviously Mr. Spirit Crows deploying some method, yet no one can tell, which is quite astute."
Li Yuhang realized: "Truly remarkable."
