Dragon Slaying: The Strategist

History graduate Shen Zhe travels to Great Yan and becomes the son-in-law of the Su family, only to discover his entire in-laws are also time travelers. To survive, he hides his identity and uses local wisdom to secretly resolve crises—from aristocratic monopolies to imperial assassinations—making every move carefully. Shen Zhe and Su Qingyu work together to help Prince Murong Sheng of Fan Yang ascend the throne, completing their dragon-slaying plan. Once the new dynasty is established, Shen Zhe steps away from power and returns to Jiangzhou with his wife. Mutual suspicion between ruler and subject leaves a lingering echo.
