Magma Release: A World of Volcanism

This jutsu is the Highest Magma Release Technique known in the shinobi world.

The user concentrates their chakra inside and outside their body before releasing it under themselves. Underground, the chakra travels extremely fast and very deep underground, going as deep as the outer mantle, and as wide as 80 km. Seconds later, large, super heated magma columns burst forth from the ground, shooting over 150 feet into the air, causing globs of magma to rain from the sky. As the magma covers everything in its path, it heats up the ground, incinerating anything in its path as well as heating the surrounding environment, vaporizing nearby bodies of water. Minutes later, the ground is covered in enough magma to simulate a sea of magma, similar to how Earth was in its early stages of life, when volcanos dominated the lands.
