Please help me find an old sci-fi manga/manhua about space handyman

Hi i am trying to track down a manhwa/mahua i read a while ago I cannot find again.

Plot is main character either returns to past/enters the space based game he played. Knows all the best leveling spots and missions. Gets one to clean trash in trash chutes but ends up falling down and has to work with little aliens/squids/octopus cleaning pipes and trash to complete mission to level up. He finally gets max affection with the creatures then gets out gets special reward. Then proceeds to level up quickly eventually working in space mercenary group scavenging broken alien machines for parts.

Sorry i know its vague.
