Exiled to the Frontier: I Can See Everything

One hundred and eighty-seven exiles are thrown into an abandoned frontier city with only seven days of rations left. Ji Hengqiu, a modern vocational school employment office teacher, transmigrates into the body of a low-ranking clerk holding a tampered household registry. Yet, after others voluntarily accept tasks, he can see their true talents. A timid butcher is best at saving horses, a lock-picking thief can craft measuring tools, a failed accountant can find water, and a disgraced scout can train a ragtag group into a city-defense squad. This registry provides no grain, no soldiers, and cannot train anyone's skills. All Ji Hengqiu can do is place misplaced people back in the right positions and bear the consequences together with them. Seven days later, officials arriving to collect corpses find lanterns hanging over the city gate for the first time. Eventually, a saying spreads across the entire frontier: In Lisha City, there are no useless people, only those who haven't found their place. — Description from novelcodex.org
