"Searching for Buddhist Scriptures from the West" is the "No. 1 Image project" designated by the top leaders of the three worlds. The story takes place in the core department responsible for operating this project - the "Tianting Lingshan Joint Major Project Office" (referred to as the Project Office).
This is a "special operations agency" that exists outside the Thirty-Three Days and is independent of the existing bureaucracy. It reports directly to the Jade Emperor and Tathagata. It has the temporary highest authority to mobilize resources from the three realms, but it also brings together all the thorniest interests and hottest potatoes.
