This jutsu is a combination of the Summoning Technique and Earth Release jutsu; the user summons a large amount of rock form a giant canyon to be used for other jutsu. Fudo can channel his chakra into the earth to alter the formation, aiding him in sneak attacks. Alternatively, by offering a donation of blood, he can summon a rock in the design of one of Fuen's drawings.
This jutsu also can be used as a medium for the Earth Release Resurrection Technique: Corpse Soil technique.
