There's Always Someone Trying to Bother My AFK Life

He deliberately chooses to work on an assembly line despite his impressive background and potential for success, shocking his coworkers with his exceptional efficiency while appearing asleep. He now has the flexibility to engage with things he enjoys, like watching movies and playing video games.
Unbeknownst to his coworkers, his secret rests in his System, a magical System that helps him easily handle routine jobs. He first enjoys the ease, but with time, his reliance on the System causes him to become lethargic. He quickly learns that the System only responds to his commands and can be stopped at any time. While it might be ineffective for complex tasks like tests, it could identify patterns and adapt to new situations.
Unexpectedly, his suspicious behavior attracts the attention of unique creatures threatening his life. In a bid to protect himself, he activates the self-defense command of his System. To his astonishment, the System transforms him into a vessel for numerous martial artists and combat grandmasters, bestowing him with lightning-fast reflexes and heightened thinking and disrupting his AFK Life.
