An Old Investigator, from a Survivor to a Secret Keeper

Mo Yu, an ordinary young man from modern times who is well versed in the Cthulhu mythology, accidentally traveled through time while watching a grand event. He did not arrive in the paradise of swords and magic he expected, but instead fell into a Victorian-steampunk-style alternate world "Norn" that was prosperous on the surface but corrupt on the inside. Here magic and machinery coexist, dragons and airships dance together, but beneath the surface of all prosperity is the silent infiltration of the shadows of the old rulers and outer gods. Mo Yu is penniless at the beginning, and is forced to struggle to survive as a low-level "abnormality investigator". His golden finger is not an invincible system, but an "information gap" about the Cthulhu mythology system before traveling through time - a "Death Note" about an indescribable thing.
