Lin Fan wakes up in a strange world overrun by beastmen and plagued by constant warfare. He has transmigrated there and has become something that is not quite a beastman, with a long tail and a two-meter-tall werewolf at home.
In this world, some beastmen join human forces to fight for living space, while others join the extraordinary beasts. The two sides have been at war for a thousand years, and human territory keeps shrinking. Soon, humanity will be enslaved by the extraordinary beasts.
Humans are weak and insignificant. Their only advantage is that they can use their spiritual power to form bonds with beasts, gaining access to beastmen's beast hearts and beast skills. Only powerful spiritual energy can make human warriors stronger and stop the extraordinary beasts from invading.
This world needs geniuses and extraordinary warriors. The only way forward is to cultivate without end and challenge ever more powerful wild beasts.
But the extraordinary beasts don't seem willing to give humanity that much time. The ten-year peace agreement is on the verge of becoming a scrap of paper...
I possess a beast heart that sees clearly, allowing me to discern every beast...
I possess spiritual chains that let me seize beast-heart energy at will and use it as my own.
