Mysterious Resurrection: Controlling the Black Umbrella Ghost at the Beginning

Jiang Chen woke up on the bus on his way to an outing, and everything strange began here. The heavy rain that seemed to swallow everything opened up a corner of the world for Jiang Chen. Evil ghosts brought harm to the world, but there was still a weak dying fire. This book is a fanfic of Mysterious Resurrection. The black umbrella ghost controlled by Jiang Chen is not exactly the same as the black umbrella, but equivalent to the puzzle piece in it, so Jiang Chen can control it.
