The third ice road of the water system pavilion is impassable.

The characteristics of ice cubes are: cracks will appear when you step on it once, cracks will appear when you step on it for the second time, and the protagonist will fall into the basement.

To see boss, every layer of ice should be stepped on "once", which means "one stroke".

Crush all the ice and the stairs will appear.

Note: the last step must stay in front of the stairs, otherwise even if the stairs appear, you can't get up.

After seeing the Boss, start playing! It is strongly recommended to use an electric system.
