Road and Return

In this world, power is never "earned," only "rented"—the rent is yours. Fu Chen is the most inconspicuous freelance detective in Iron Rust Port, and he takes cases that no one cares about. His ability "Order Perception" can detect anything "wrong" in space, but he doesn't know that every time he uses it, it consumes his personality. An anonymous letter, an old iron nail, a door that has been sealed for thirty years - seven cases, strung together into a complete old road. What he was investigating was never other people's affairs, but his own erased past. There is a door at the end of Rust Harbor. He is not here to investigate the case, he is a key. But he didn't know if he would remember who he was when he opened that door.
