Midgard, the Alpine Mountains.
Luo En stood amidst the biting cold and blizzard, gazing at the endless towering peaks ahead. He raised his head to glance at a massive black crow perched on a withered tree branch, preening its feathers:
"Mulin, are you sure this is the place?"
"Relax, it's right here, no mistake!"
The black crow spoke with human words, its tone utterly confident.
In Nordic Mythology, two gigantic ravens often roosted on Odin's shoulders: one named "Haki," representing "Thought," and the other named "Mulin," representing "Memory." These two ravens flew daily across the Nine Great Kingdoms and reported everything they saw and heard to Odin without reservation, serving as extensions of his will and eyes.
Furthermore, each raven had its own unique traits. "Haki," representing "Thought," was faster and well-suited as a scout; "Mulin," representing "Memory," possessed an unerring recollection, essentially acting as a living map.
