Летопись королей Западного края

Four individuals, Yuan Mo, A Shu, Wang Kun Wu, and Yu Chi Hua, embark on a journey for their nation and justice. During the peaceful Daming Dynasty, Yuan Mo, a commoner in Changle City, inadvertently becomes involved in international affairs after an altercation with A Shu, a refugee. This leads to Wang Kun Wu's punishment and Yuan Mo's assignment to the Four Square Pavilion's western office. Alongside A Shu, his new maidservant, Wang Kun Wu as his superior, and the powerful Yu Chi Hua, Yuan Mo matures while handling complex diplomatic issues, despite being mocked as "useless."
