My Tattoo Can Communicate with Gods

My name is Jiang Chen. During the day, I am an ordinary administrator in the city library. I am taciturn and aloof from the world. At night, I am the last night watchman in this city. Urban legends, mysterious anecdotes, monsters from the ancient "Book of Mountains and Seas" resurrected in the shadow of modern times... These are all under my control. They thought I was just a weak scholar, but they didn't know that the ancient tattoos on my body could communicate with gods and kill gods. When the shadow of the "Smiling Corpse Case" enveloped the city and everyone fell into panic, the arrogant official investigator turned his scrutiny to me, the "first discoverer." He would never know that the taboo truth he was searching for was sitting quietly across from him, adjusting his glasses and pouring him a cup of hot tea. ——Watch the night and protect you at dawn.
