I Died in My Brother's Place and Became the Federation's Marshal, So What Do You Regret?

[Decisive and ruthless + intelligence gathering + slaying the uncanny + rule-based horror] After transmigrating to the apocalyptic era, where the uncanny runs rampant, Ning Ye has spent three years surviving before his biological parents find him while searching for their long-lost child. He expected warm concern and questions about what he wore and ate. At worst, he thought they might pretend to care. Instead, they used emotional blackmail, demanding that he take his sequence-ranked, superhuman younger brother’s place in the Special Anomaly Bureau’s uncanny assessment. The Special Anomaly Bureau is the highest authority in an apocalyptic city, responsible for handling uncanny incidents. The assessment is a death sentence for sequence-ranked candidates, let alone an ordinary person. Fortunately, Ning Ye awakens a Daily Intelligence Case System, which lets him discover uncanny beings and vengeful spirits hidden deep within human hosts, and uncover their abilities, weaknesses, and rules. “The Special Anomaly Bureau is the highest authority in an apocalyptic city. If you pass the assessment and get in, you’ll have power, benefits, and a good salary. What more could you want?” “I’ll take the assessment!” “But for the sake of my loved ones, you’ll have to pay extra!” After severing ties with his family, Ning Ye heads to the Special Anomaly Bureau for the assessment. Using his intelligence on the uncanny’s rules and weaknesses, he takes first place, becomes an uncanny investigator, and rises to the ranks of the sequence superhumans. From then on, uncanny beings hiding in the city can no longer evade investigation, and wasteland mutants affected by the uncanny can no longer escape detection. In the year 2055 of the apocalyptic era, Ning Ye, now the Federation’s supreme commander, is under investigation: “By rights, someone of your rank as a sequence user doesn’t have the authority to investigate me.”
