An international crime syndicate hijacked a luxury cruise ship at sea, specifically demanding the presence of Shao Lin, an expert negotiator from the international rescue team. After several groups of hostages were successfully ransomed, the ship suddenly exploded, leaving no survivors from the last group of hostages—including the rescue workers. A year later, those who had been successfully rescued began to die one after another… Meanwhile, the Yan'an City Criminal Investigation Division received a photo—the negotiator who had perished in the ocean bore the exact same face as the new psychological consultant in their department. This man wrote with beautiful calligraphy, memorized case files effortlessly, and had a black rose tattooed on his waist.
