According to Jin Zhong, the Great Book Collection is an independent building located on the east side of the Mechanical God Sect's Holy Hall.
This building is divided into three levels, with the first level being a relatively public literature and history materials floor that all Holy Temple Guards can enter.
Going further down are the secret layer and the top-secret layer, where the Mechanical God Sect's most classified knowledge and little-known information are kept.
Generally speaking, only religious personnel at the archbishop level can enter the second level, while the third level is only accessible to successive Saints, namely the Black-clothed Archbishop.
If the Mechanical God Sect indeed holds knowledge about the beast tide, then undoubtedly, this information and records would be placed on the third level.
How to enter the third level becomes the present difficulty.
