After accepting the emperor's order, he quickly handed over power and returned to the capital. However, due to his great achievements, he was jealous of the emperor. Zhao Zhongyuan was thrown into a prison. Zhao Zhongyuan, who has already understood everything, secretly planned it just to protect his family. In the end, helping the prince ascend the throne brought stability to his family and the world.
