The Yao Dynasty was in turmoil. Shen Qingci, the legitimate daughter of the general, and Xiao Che, the third prince, once made love on a lantern night in Chang'an. A "Northern Starlight" jade pendant tied up their deep love in troubled times. However, under the pressure of the imperial power, the Shen family was framed and everyone was wronged. She went from a bright warrior to a prisoner. He ascended the throne as emperor and locked her up in the palace. Misunderstandings cut through love and hate like a knife. She lost her voice after being poisoned, grew old in the cold palace, and lost her son. She spent all her glory in despair. When the truth about the conspiracy and his forbearing plot finally came to light, and the palace turned into a fire, she protected her young son from the deadly rain of arrows. When the cinnabar tears are gone, the imperial city is empty. He holds the broken pendant in his hand and looks north every year, feeling regret for the rest of his life.
