Reincarnated Into a Game as the Hero's Friend: Running the Kingdom Behind the Scenes (Light Novel) Vol. 7: Part 1

What once appeared to simply be a video game world brought to life is becoming more complex. Werner von Zehrfeld discovers that the kingdom's greatest secrets may have something to do with the underground library's construction rather than the books it holds. Werner has long been underestimated, but when he becomes the target of an assassin and is lured into a trap, maybe it's a sign that his enemies are starting to take him seriously.
