Gu Chen accidentally transmigrated into the beast-taming world, only to find himself unable to awaken beast-taming talent, becoming a good-for-nothing laughed at by everyone. Just as he was about to give up, the system suddenly arrived, but an outrageous binding occurred—the system host turned out to be a husky he raised, Tuantuan! From then on, a man and a dog started their path of counterattack. Relying on Tuantuan's hidden mysterious bloodline, Gu Chen constantly completed tasks and improved his strength, growing gradually through secret realm explorations and powerful enemy challenges. When everyone thought he was just a trash living off his pet, Tuantuan's true power gradually awakened, and Gu Chen stepped step by step toward the peak of the beast-taming world.
