The Book of Mythical Beasts

Heavenly fire fell from the sky and mythical monsters emerged, plunging the world into chaos. The imperial court proclaimed that whoever could tame the mythical monsters would be richly rewarded with status and wealth. An organization to fight the beasts, the Beast-Subduing Department, was established, and a hero ranking list was created. As the mythical beasts faction gradually gained power, Hua Manteng, who wanted to become king, assassinated the emperor and mercilessly massacred the people. And so the humans battled against the mythical beasts, all of whom served their own masters.
