Super-Powered Urban Loser Starts Dungeon Technology

Chen Rang, an F-level electrical power user, can discharge with full power, which is equivalent to inserting two fingers into a socket. When he was slapped away by a monster on a mission, he was dragged to another world by an unreliable goddess, and was then told - I forgot to send you the golden finger in your previous life, and the summons this time was also wrong. The devil has been killed long ago, and I am just too busy. The good news is that he got compensation: a dungeon entrance that can be accessed at any time, and a mechanic system. So, the most useless student in the theory class in the college started doing one thing: working as a power bank in class during the day, and downloading dungeons to beat up slimes at night. While others were still competing for power levels, Chen Rang took out an enchanted pistol. When others thought he was just lucky, his robot army was already mining automatically in the dungeon. When the genius girl who mistakenly took the golden finger that should belong to him stood in front of him with a red face and said that the system always calls your name me - Chen Rang felt that his life seemed not so useless anymore. Power level F, equipment level legendary. Who says trash can't be turned around? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
