After the Fertile Continent was torn apart by the "War of Broken Old Gods", the Behemoth clan retreated to the southern "Blackstone Mountains" and were divided into classes based on "purity of blood": pure-blooded lion-man Behemoth held the royal power, bear-man Behemoth guarded the border, and eagle Behemoth controlled intelligence. Hybrid Behemoths were regarded as "bloodline stains" due to their "mixed strength" and were often reduced to slaves or cannon fodder.
The protagonist "Munch" is the illegitimate son of a lion warrior and a bear slave. He was born with the hybrid characteristics of "lion's mane and bear claws" and was hidden by his mother in the "Dry Bone Valley" deep in the mountains - where the hybrid Behemoth was abandoned. Before her death, her mother left behind half a piece of black stone engraved with the "reverse scale" pattern, and warned him that "blood is not a crime, but strength is respected", but she did not reveal the truth about the pattern.
When he was ten years old, the Valley of Dry Bones was "cleared" by the pure-blood harpy Beamon. Munch witnessed his companions being brutally killed, and the blood in his body suddenly rioted: the lion man's explosive power and the bear man's defensive power briefly merged, and he actually tore apart the low-level harpy Beamon with his bare hands. But this outbreak also exposed his traces, and he was listed as a "must get rid of the miscellaneous blood" by the "Black Stone Throne".
At this time, undercurrents were surging on the continent: the northern human kingdom coveted Beamon's "beast core power", the eastern elves were repairing the ruins of the old god, and within the Beamon kingdom, the pure-blood nobles were constantly fighting among themselves for the "bloodline sacred object" - no one knew that the mixed blood in Monk's body was the bloodline residual image of the "first generation Beamon" in the old god era, and that half of the black stone was the key to unlocking the "bloodline truth".
