Earth Release Resurrection Technique: Earthen Corpse - a ninjutsu that allows raising fallen fighters, using ordinary earth instead of flesh and bones. Kazuma called it the supreme resurrection technique of the Earth element. The technique has two completely different uses.
The first is the mass raising of the dead. The user literally molds dozens of mindless zombies out of soil, which charge at the enemy as a solid wall. There is little use for them in terms of tactics or strength - they retain neither reason, nor combat skills, nor techniques, and crumble from a couple of good hits. But they can be generated almost endlessly as long as there is enough earth underfoot. As soon as the user deactivates the technique or dies, this entire army instantly turns to dust.
The second is the targeted, full-fledged resurrection of a single specific fighter. In this case, the raised dead gets everything he knew in life: from physical form to an arsenal of techniques. However, the soul does not return to such a body, so there can be no talk of any regeneration - he can be killed like an ordinary person. In addition, a rigid directive is imprinted into his head, which he is forced to carry out even if he is fully aware of his actions. This variant requires a powerful external source of energy, for example, a discharge of electricity. To cancel the technique, it is enough to form the Snake seal and snap one's fingers - the resurrected instantly crumbles into loose soil.
