Liu Xing transmigrates into a world of beast taming. After Gao Bo accidentally causes his parents to fall into comas, Liu Xing also becomes a low-ranking beast tamer. When his system awakens, he contracts a Hellhound with the bloodline of the Darkflame Wolf King and begins his journey of rising above his circumstances. He defeats Gao Bo and the Gao family forces, then enters Huaxia Academy for further training. Facing the Blood Demon Clan, dangerous secret realms, and the legacy of the Ancient Dragon King, Liu Xing continuously breaks through his limits. Eventually, he contracts a Sacred-Winged Young Dragon and embarks on the path to becoming the world's strongest beast tamer.
