Start Clearing the Nightmare Game by Picking up Trash

I, Ai Ge, am a poor student who can't even pay the tuition. I deliver food during the day and work in "Nightmare Game" at night. The initial occupation assigned to me by the system was Goblin Engineer. Skill effects are: picking up garbage, tearing apart rags, and rubbing toys. When others are fighting the BOSS in nightmares, I'm busy breaking down battlefield waste and synthesizing some not-so-serious "arts." "Hey buddy, that's the battle puppet I synthesized. Can you be more respectful?" "Oh, I'm sorry, it's so realistic that I couldn't help it." "Oh my God!... Do you know that you have to pay extra?"
