At this time, the ghost hand skill is upgraded, and the gyro can be started with the ghost hand. After you start the gyro with the ghost hand, (in the same way as you usually catch monsters), cut it with a sword until it rotates, and then push it out with the ghost hand. It will destroy everything on the road, including the blocked door. Break that door and you can go out.
Gyroscope is to find something standing in the room, which looks like a pile of iron.
