No one knows how many years ago it began—when the Demon Gods descended, unleashing slaughter and catastrophe upon the world. Earth was plunged into an apocalyptic transformation, teetering on the edge of extinction.

Terrifying alien monstrosities, powerful savage beasts, spreading demonic miasma...

Ancient lost civilizations, primordial ruins, and mysterious dimensional rifts all began to surface.

Who could bear the responsibility of saving all life on Earth?

Mage? Swordsman? Warrior? Cleric? Gunner...?

None are worthy!

Only Beast Tamers can shoulder this burden!

This is a world ruled by Beast Tamers.

The protagonist, Lin Chen, crosses into this realm—but unlike others, he has no cheat, no golden finger. In fact, his talent is the lowest grade possible: F-rank!

And yet, Lin Chen remains completely unshaken.

“You visualize your beast compendium—I visualize the Classic of Mountains and Seas.”

“You form a pact with a six-winged pegasus—I contract the Candle Dragon.”

“You tame the Hellhound—I summon the Golden Crow.”

“You ride the Four Great Primordial Dragons—I command the Four Great Fiends.”

...

Years later, Lin Chen leads an army of divine beasts from the Shan Hai Jing as he gazes upon the alien gods’ realm, smiling faintly.

The gods… tremble to their very core.

The era of universal job transfer has begun, the planes of the heavens have invaded the Blue Star, and professionals have become the defenders and masters of the human race.
