Under the surface of the bustling city, there are countless unspeakable horrors and secrets hidden. Lin Yuan is an ordinary person who accidentally stepped into this dark realm, but he is destined to have an extraordinary destiny. Lin Yuan is not a born brave. At first, faced with the terrifying appearance and mental erosion of Cthulhu creatures, he was fearful and hesitant, and was shrouded in despair countless times. But in a desperate situation, his inner tenacity was stimulated. Relying on his extraordinary memory and logical thinking, he looks for ways to fight terror in ancient books and secret legends. Every encounter with the unspeakable thing was like leaving a mark on his soul, allowing him to gradually adapt to and resist this darkness.
During the adventure, Lin Yuan met all kinds of partners, including old men who knew the occult, and strangers who had special abilities but were isolated from society. Together, they traveled through abandoned ancient manors and gloomy deep-sea ruins, where there was an atmosphere of decay and despair, and deadly dangers lurked in every corner.
Lin Yuan constantly challenges his own limits on the road to pursuing the truth. He once faced the crazy will emanating from the Old Ones. On the verge of mental collapse, he broke away from the mind-destroying power by relying on his persistence in survival and truth. As he gained a deeper understanding of the world of Cthulhu, he discovered that his fate was closely linked to the survival of the entire world.
He knows very well that human beings are as small as ants in this vast universe. Facing the terrifying power of Cthulhu, the hope of victory is slim. But he still chose to come forward.
