Mystery Yellow Cave Sky opens its doors every Jiazi cycle, yet each opening is not the same region. It is only during a One Yuan cycle that a complete opening occurs.
A One Yuan cycle is one hundred twenty-nine thousand six hundred years long; Ji Feixue couldn't wait that long.
The last great opening was nine thousand years ago when a foolish dragon had an accident within Mystery Yellow Cave Sky and left behind a piece of Dragon Scale.
That was the only thing the Dragon Clan could use to trace their Dragon Ancestor, and it was not to be lost. But the unopened regions of Mystery Yellow Cave Sky, with their Dark Tides surging, eroding the Divine God Soul, forced entry meant almost certain death.
Instead, for Su Huanian, with a Boundary Status not so high as to provoke strong Dark Tide surges and yet possessed of a fearsomely strong Divine God Soul Spiritual Intensity, he could move through that place as if it were level ground.
