On the other side, having entered the palace, Ling Feng began to scrutinize the surroundings.
This place is a superb cultivation treasure land, with the density of Spiritual Energy in the air making one's jaw drop.
"If I were to directly cultivate here, I fear that within ten breaths, I would be able to directly break through to the Third Level of the Heavenly Destiny Realm!"
Ling Feng's heart became fervent; although he had never entered the so-called Nine Yang Cave Heaven, the cultivation effect here must far exceed that place by hundreds or thousands of times!
After carefully examining the hall, Ling Feng's gaze finally fell upon a mural of a dragon and phoenix.
"There is something strange about this mural."
Ling Feng was surprised within his heart, and after scrutinizing for a moment, he discovered that the eyeball of the Dark Dragon at the center of the mural seemed to be missing something.
The position of the eyeball appeared to be a groove!
