UP DOWN magical float balance

You can switch quickly between up and down spells. I came from a country of this steaming stone, but this time I tried to squeeze it using the chain. There is a magic ball on the top of the magic crucible. If you raise it (if you are on the surface of the water), it will go up and go fishing, and if you lower the magic ball (sink under the water) It is possible. The needle collar is said to be used as 8cm for uphill fishing and 8cm and 20cm for lowering fishing.
