Xie Yunlan was reborn. In his previous life, he spent all his efforts to cultivate the divine pet, but was easily crushed by his opponents in the academy arena using "system abilities", and finally died with hatred. In this life, he returned to the month before he was about to participate in the academy qualifying competition. What shocked him even more was that his opponent in his previous life, now the academy's "favorite", turned out to be a manipulator with a "system"! That system can strengthen pet beasts, cheat to improve them, and even steal other people's training results. However, Xie Yunlan's Golden Finger looked extremely "waste" - just a white-haired little beast that looked the most ordinary, with no system, no panel, and no even skills. But Xie Yunlan soon discovered that this little beast had incredible potential - it could swallow the system energy of the opponent's pet beast and convert it into its own strength. Thus, a seemingly disparate revenge began. Facing a talented opponent with a system, Xie Yunlan relied on the experience accumulated in his previous life and his ultimate understanding of pet beasts, and took his "pet" step by step to break the rules and counterattack in the academy arena. In the process of defeating the system operators again and again, he gradually discovered that there was far more than one system operator in this world, and a huge conspiracy was slowly unfolding behind the academy.
