In a world where beast-controlling is dominant, a man named Ling Tian transmigrates and unexpectedly obtains a golden finger. He witnesses the evolution of his mount from a Spirit Water Horse to a Water Cloud Horse and eventually a Heavenly Water Frost Moon Horse. His system is even more surprising, containing a Monster Hunter DLC! He encounters and captures powerful creatures like the lightning-fast Flying Thunder Dragon, the forest tyrant Brute Jaw Dragon, and the Sky King Fire Dragon. His journey is filled with rewards such as marrow-washing pills, beast-controlling contract scrolls, and the Beast Star Imperial God Manual. Years later, an elder respectfully addresses him as the young master of the Ling family, a legendary figure whose power caused a cataclysmic battle known as the Twilight of the Gods. This novel blends elements of beast-controlling, evolution, a system, and cultivation.
