During the Xining era of the Northern Song Dynasty, Emperor Shenzong Zhao Xu ascended the throne. 欧阳修, 韩琦, and 富弼, once prominent figures, were nearing the end of their careers. Wang Anshi, full of ambition, sought to change the course of the empire, while Sima Guang, remaining in the shadows, steadfastly guarded the fundamental principles of the state. Su Shi, meanwhile, cautiously observed from the sidelines, unable to decide which side to support. This was the final glorious moment of the Northern Song's greatest team of civil officials, yet these brilliant minds chose a path of mutual destruction, leaving behind a deep wound on the Song Dynasty and sparking endless regret and debate in history.
