For the past twenty-five years, I have dipped the tip of my needle in ink and carved marks into my clients' skin. I am Chen Mo, the chief tattoo artist of "Tianlei Tattoo". I have witnessed the changes in this historical town. Each mark I personally pierced carries many desires and stories. And among them, eight people remain - eight completely different works, but they seem to be entangled with the same thread of fate, imprinting a period of our bizarre and strange years.
In just thirty days, bad news fell like hail: three people died unexpectedly, and the reports were unclear; one person was imprisoned, and the charges were shrouded in mystery; there was no news about the two people, as if they had disappeared from the world. Who was peering at the underground funds that followed them everywhere, and instantly turned into an abyss that swallowed everything?
When the two remaining old friends, full of panic and fresh blood, opened the heavy door of "Tian Lei", I knew that the storm was coming. They want to use my intricate connections to dig out the truth in the shadows of the city. But the murderous intention came faster and colder - before they could ask for help, the silencing blade had accurately targeted me. In the gaps between being hunted, those "carriers" with unique skills scattered in the city became the only vines I could cling to. How can we see clearly the truth behind those eight works, which was completely distorted by greed and betrayal? And the first touch of scarlet has silently soaked the mottled threshold of the "Thunder Tattoo".
