Change Your Job as a Scavenger and Get a 10,000-Fold Refund for Picking up Trash?

Traveling through the parallel world, games and reality merge, and mankind has entered the era of universal job change. Jiang Heng was completely inactive for three years because he was transferred to the most useless hidden profession of 'Scavenger'. He was useless except for picking up garbage and could not even hold a auxiliary profession. What should I do if I repeat three years and fail to graduate? The 10,000-fold return system is activated as soon as you travel through time! "You picked up a tattered dagger. Return it ten thousand times. The enchanted weapon has the property of 'guaranteed hit'!" "You collected a marrow-washing fruit, which strengthens the effect ten thousand times, and you get a thousand-year-old marrow-washing fruit!" On that day, Chen Lin quickly cleared the entire school's dungeons, setting a record high in clearance! "Scavenger is not a profession that collects garbage? Why can I just clear an S-level dungeon!" "When will La** be able to pick up god-level equipment? I'll go too!" "He even wiped out all the monsters in the dungeon for points. I cried to death~" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
