I Knocked Out a Realm Beast with One Punch, How Can I Not Be Considered a Genius?

Lu Wen traveled through time and space to a world where beast control was the most important thing. Good news: the original owner is a genius! Bad news: I inherited no memories from the original owner. Bite! The system is coming] Just when Lu Wen pinned all his hopes on the system... "Ding! Congratulations to the host for insisting on his own gender, not compromising to xxn, and now activating the [Strongest Fighter System]!" Lu Wen:? ? ? No, what should I do? ? Therefore, under the driving force of pretense, the incident will always be solved inexplicably and miraculously. From the realm experience to the academy competition, from the wild realm to the hammering world. I just want to ask... Who else can withstand my punch?
