Wan Shi Tong's Library (Earth-2213)

"This library is more valuable than gold, little lady. It is said to contain a vast collection of knowledge, and knowledge is priceless."

- - Professor Zei to Asami Sato

Wan Shi Tong's Library, also known as Wan Shi Tong's Spirit Library, was a gigantic library within the Spirit World. However, up until 17 AG, it was found at the Si Wong Desert, in the Land of Wind, becoming a fabled destination for any shinobi who dared to cross the desert and hoped to live. Because it was almost completel buried under the desert's land, the library was very difficult to locate.

History
The library was built around 9000 BG by Wan Shi Tong, who intended on preserving all knowledge of the Shinobi World on it. With time, the library became home to a vast and ancient collection of books, notes, culture and legends gathered by Shi Tong's knowledge seeker spirits. Around 800 BG, the library became accessible to humans in what was later named the Si Wong Desert, on the Land of Wind, as Wan Shi Tong hoped they could positively benefit from all knowledge and information he collected through the ages. However, some shinobi sought for secrets to destroy their enemies and start wars. Angered by their abuse, Wan Shi Tong killed them all and closed his library.
