When Gu Chenfeng and the others rushed into the Secret Realm's space and approached the enormous tower that rose over a thousand zhang high.
A Jade Talisman appeared naturally in each person's hand.
These were teleportation Jade Talismans, each usable twice to enter and leave the Nine Dragons Suppressing Prison Tower.
Gu Chenfeng and the others held their Jade Talismans, infused them with energy, and willed them to activate.
Whoosh, whoosh...!
The next moment, all four had shifted into the first floor of the Nine Dragons Suppressing Prison Tower.
The instant they entered this space, a wave of heat struck them in the face.
Gu Chenfeng looked around and saw a murky yellow sky and crimson earth.
The vast land was nothing but scorched soil and dry, cracked gullies, while surging gusts of scorching wind swept through heaven and earth.
It was like standing in a barren desert.
Even stranger was that the moment they stepped into this space.
The Heaven and Earth Origin Power within their bodies began depleting continuously, as though being vaporized by raging flames.
"This is the Refining Land on the first floor of the Nine Dragons Suppressing Prison Tower. This place can refine away the Heaven and Earth Origin Power of living beings. The deeper you go, the stronger its refining power becomes."
Ao Li explained.
She had already given Gu Chenfeng a general account of the situation inside the Prison-Suppressing Tower.
The Prison-Suppressing Tower's first five floors corresponded to the five elements of Metal, Wood, Water, Fire, and Earth, each with different trials.
Some opportunities and treasures would also appear.
Farther up, there were even powerful demonic beast souls condensed by the tower roaming about.
To reach the Seventh Layer, one needed strength at or above the Half-Step Source Emperor Realm.
