In the Cultivation World, I Pick Up Trash and Ascend to Immortality

Female protagonist + no romance + cautious cultivation + decisive and ruthless + lone-wolf protagonist

Yun Qing transmigrates into the cultivation world and binds herself to the Heavenly Dao Janitor System.

Her daily task is to clean up the trash cultivators leave behind in various secret realms.

The prodigies of the immortal sects sneer at Yun Qing: "A mere cleaner thinks she belongs in a secret realm?"

Then one day, Yun Qing finds a discarded, defective pill in a garbage heap.

She casually purifies it, revealing its pill markings: it is none other than the long-lost Nine-Turn Violet Gold Pill from ancient times.

The immortal sects go wild: "Fairy! Our sect has plenty of trash heaps! Please come clean them!"
