System: I'm from a Family of Spirit-Beast Breeders

【System + spirit beast space + wild imagination】 When other people transmigrated, they got powerful Systems and piles of rewards, with treasures, spirit stones, and beautiful women in abundance. Zhao Tianli transmigrated too, and he got a System as well. Unfortunately, it only ever gave him two things as rewards. No treasures. He would have to earn his own spirit stones. Beautiful women... Wait, that was an option? Zhao Tianli never imagined that he would become powerful one day. After all, his original dream was nothing more than keeping his family safe and graduating without a hitch. He never expected that one day he would become the savior of the world! Zhao Tianli was baffled. Wasn't this how you normally clear the game? Why was it different for him...?
