Destroy the Prefabricated System with One Punch!

This is Dean's first time fighting three system monsters. A brave man covered in legendary equipment, a witch with 500 entries, and a 1.2-Meter muscular monster who is only eight years old but has 1,000 points of power... This horse is eight years old! ? They don't know that their system was prefabricated by Dean using garbage—— Dean spun and jumped with his eyes closed, his left hand slapped away the brave man who bullied the young rich man, his right hand blocked the witch's mouth that said "I will live again, I will...", His feet flew in a spiral of lightning and kicked the eight-year-old Arnold who was crying and was still enjoying himself... Kill! Kill! Kill! Kill until there is no system in the world! Kill until the world is peaceful! " ………… And when the Savior went through hardships and climbed the last step of the heaven for ten thousand years, he looked up and saw that Dean had been lying here waiting for a long time: "Uh, why did I forget you? What you heard was not the sound of the system, but the barking of my dog. " ………… In the end, Dean will cut off this prefabricated fate and ending.
