Mountains hung upside down, waterfalls flowed in reverse.
An illusionary mirage-like scene appeared in the distant azure sky.
That mountain range stretched endlessly, and the waterfall flowed upward into a vast lake.
Inverted Mountain!
It marked the boundary between the outer and inner circles of the Secret Realm!
This was not so much an obstacle, but rather, the realms inside and outside of the Secret Realm were inverted.
They needed to cross from this side to the other, flipping into another piece of inverted land.
Separated by a great distance, there was considerable pressure in between. Even feathermen, birds, angels, capable of flight at the Fourth-order Limit, could hardly fly over this chasm.
Only those in the Legendary Realm, wielding the Power of Heaven and Earth, could cross it.
And even for them, it wasn't easy.
Carrying others with them made it even more difficult. Newcomers to the Legendary Realm were not even qualified to watch over others.
"Sreee~"
