Sage Art: Ghost City Resurrection:

A technique created by Sannoto Senju, it remains one of his strongest techniques to date, using it when he finds the time absolute necessary. As the name speaks, this technique is one that allows Sannoto to generate an entire city, created from a different array of metals. Instantaneously, Sannoto can erect a city of metal that he can then manipulate, essentially being an entirely new environment that he created. With control over this city and the largeness of it, Sannoto supplies the advantage of being capable of shifting his environment drastically to suit his needs.

By taking in natural energy from Tai, Sannoto infuses it with his chakra to amplify it, allowing him to preform this technique, as his normal chakra reserves are much to small to complete this technique. Following this, Sannoto uses his senjutsu chakra, releasing it from all points of his body at extreme speeds to spread out across the entire area, turning the earth and air into metals of all kinds.
