Steel Release: Creation Matrix

A secret technique developed by Ginzo.

The user concentrates chakra into their body before placing their hands on the ground, causing the chakra to attract steel all throughout a several mile radius underground to their location. The innumeral steel fragments burst from the ground in geysers. The steel fragments then quickly create constructs limited only by the users imagination, forming everything from buildings to weapons.

Ginzo used this to take over a country before creating his army of androids.
