Relying on Loopholes in the Rules: I Will Travel Across the Three Realms to Become a Boss

Lin Fan, who had a useless body of five elements, was pushed off a cliff and awakened the "Vulnerability Detector"! Is the world of cultivating immortals a system of heaven? Ordinary fire can be used to refine magic elixirs, scrap metal can be used to create magical weapons, and even the ascension review can be passed with bugs! He searched for loopholes in the rules of the three realms, slapped geniuses in the face, played tricks on villains, and formed a bug team to sweep away the immortals and demons! When the lawful ones hunted "deviants" and the multiverse administrator wanted to destroy the BUG world, Lin Fan sneered: "Perfection is the biggest BUG!" Since then, the loser has counterattacked and turned into a rule-reshaper, free in the multiverse, and started the most outrageous legend of cultivating immortals!
