In the seventh year of Xuanhe, on the eve of Jingkang, historical screenwriter Zhang Cen traveled through time and became a lonely boy in the Northern Song Dynasty.

With his 800-year prophetic advantage, he accumulated strength in troubled times, fought against the Jin soldiers, challenged the dynasty, and vowed to rewrite the humiliating fate of the Han family.
