Katsuyu: Immense Network Healing

A combination technique between Tsunade and her slug summon Katsuyu, where first, Katsuyu divides her body into several small clones, and then attaches herself to a person/persons. Tsunade will then channel her medical chakra through Katsuyu, who in turn transfers it to the wounded person, healing them. This technique allows Tsunade to heal an enormous amount of people at the same time regardless of distance, and if she runs out of normal chakra, she can use her special reserves to continue the technique. While using this technique, Tsunade is apparently linked with Katsuyu and is able to communicate directly with the slug as well as has a sense of what Katsuyu experiences as seen with her reaction after Katsuyu finds Kakashi on the battlefield, and later when she told Chōji that Chōza was still alive.
