The Paranormal Cleaner

It's more like a group portrait, and the players in the black seal have no ability to resist the evil spirits at all. So to deal with the weirdness outside, at least the white seal is required? Then I feel that Weird's advantage outside will be very large, and it is impossible to balance it. For example, for the two Weirds who are watching the male protagonist outside, the male protagonist must at least reach Baiyin to deal with her. I really can't understand this battle of wits. Obviously there are no clues. I only learned about the access card from the deliveryman. Then the deliveryman asked him to help find the ring. Why not try to find it?
