Memory and unwillingness, determination to rewrite fate. In the police world, he started as an auxiliary police officer at the grassroots level. By relying on his prediction of future case clues and crime trends, he successively solved major and difficult cases in a short period of time. However, the villains in his previous life were unwilling to see him rise. They created various obstacles within the police force, used complex interpersonal relationships and seniority disciplines to restrict his development, and also set up numerous obstacles in case investigations. Long Ci not only has to face the interference of external villains, but also the distrust of his colleagues within the police force due to misunderstandings in his past life. Under the pressure of solving cases within a deadline, he faced a difficult choice between justice and survival: should he stick to the bottom line of justice and fight the powerful villains to the end, or should he compromise with the threats and inducements of the villains in order to survive. Every time he successfully solved a case, he had to bear the painful memories of previous failures. But Long Ci relied on his gradually firmer faith and courageous character, and with the help of his helpers, he broke through the difficulties and finally defeated the enemy. He became a legend in the police world and made up for the regrets in his previous life.
