The system says there are no ghosts.

The cyber system [Heavenly Dao] declared: There are no ghosts in the cultivation world; all abnormal data is a bug that can be cleaned up. Chen Yi was the lowest-ranking cleaner, earning a monthly salary of 5 spirit stones. He lived in a tenement building with a spiritual energy concentration of 0.1, and his daily work consisted of cleaning up the "abnormal data" marked by the system. Until one day, he touched a glowing stone.
