The Library of All Realms, the cage of civilization at the end of time and space. Every book here is a complete world, every index label is a shackle of fate, and the administrator is the "annotator" who maintains the high-dimensional order, and is also the "spectator" of the low-dimensional civilization. Lin Qingxuan's ascension was nothing more than falling from the dust of one world into the cage of another's rules.
An accidental discovery allowed him to glimpse the cruel truth: his mother world, Xuanyuan Cultivation World, had long been labeled as a "tragedy material library" for high-dimensional predators, and the collusion between the library supervisors and predators had pushed countless worlds to the brink of destruction. In order to protect the Mother Realm, he did not hesitate to use his own existence as collateral, bind the God Killer's self-destruction agreement, and personally turn the Mother Realm into a forbidden book.
The fading watcher, the awakened God-killer, the secret forbidden book alliance, the remaining ancient consciousness... In the intertwined two-line narrative, Lin Qingxuan struggles with forgetfulness and obsession, while guiding the mother world to fight against external interference, while revealing the ultimate secret of the library - this seemingly neutral library was originally a tool for ancient high-dimensional civilization to trap the low-dimensional world.
When the supervisors took out the ancient weapon "Index Clearer", when the ancient backdoor of the core of the God Killer emerged, and when the door to the origin in the deepest part of the library slowly opened, Lin Qingxuan realized that he had never only protected the mother world, but also the hope of resistance of all enslaved low-dimensional civilizations. This war of indexes across time and space will never end.
