After Uninstalling the System for Good, I Get a Thousand Times Stronger Every Day

This is an unofficial fan-made parallel-universe take on the Ultimate V series. The plot and setting have been reimagined, purely for fun, so please don't take it too seriously~

From the start, a lousy System binds itself to me and forces me to become a lackey of the Demon Realm? I flip the table on the spot and sever the link! To my surprise, the System begs me not to leave and offers an outrageous compensation: my combat power automatically increases by 1,000 every day! While Wang Dadong is still worrying about his combat power, I surpass him after a single nap. KO One, here I come. I hear they don't accept ordinary people here? Sorry, I only need one day to reach the top of the KO rankings!
