The Great Sages and the Demon Lord

On top of the Sky Peak Moutain in the Southern World, there lived the Three Great Sages:

The Sage of Mind - Un Sane;

The Sage of Beauty - Hunny Mei; and

The Sage of Power - Lei Ah

Upon hearing the news from the Heavenly Father, Ruler of the Southern Empire which holds ten kingdoms in total, that the Demon Lord reappeared after vanishing from the world for a year without anybody knowing why.

Un Sane, the Sage of Mind was forced to go to the Eastern world and finish the task and save the world from the hands of the Demon Lord.

However, after setting out. The Demon Lord unexpectedly appeared in front of the stone door on top of the Sky Peak Mountain, yelling for revenge.

Un Sane was left on a goose chase for a while.
