On the day of the fall of the Western Zhou Dynasty, Bao Si died with hatred in the bloody flames, bearing the eternal infamy of "the enchantress who brought harm to the country". However, fate gave her a chance to come back - she was reborn as her thirteen-year-old self and was being sent to Hojing to "atone" for her sins. With the memory of her previous life, she saw clearly the truth about Shen Hou's collusion with Quan Rong and Guo Shifu's corruption and power grab, and she also understood how the lies on the beacon tower buried the dynasty.
This time, Bao Si put away her weakness and transformed into a dancer among thorns. She pretended to be cowardly and entered the palace, secretly observed the situation, cultivated her power, used her resourcefulness to alienate the alliance between Shen Hou and Quan Rong, and won the trust and respect of King Zhou You with her unique insights into the art of war. She collected evidence step by step and exposed the conspiracy. When Shen Hou launched a rebellion and hundreds of thousands of troops were suppressing the situation, she personally boarded the beacon tower to light a real distress signal. She wore a battle armor and fought side by side with King You. She predicted the enemy's movements from the memories of her previous life, and finally put down the rebellion and paid for her debt with blood.
After the rebellion, Bao Si did not stop at revenge, but assisted King You to implement reforms, amend the law, appease the refugees, open a school for girls, and used actions to prove that "the rise and fall of a country is not the responsibility of one person." She personally tore off the label of "beauties bring disaster" and left the legend of "the bright candle that illuminates the darkness" in history, making the bloody dawn on the beacon tower the prelude to the rebirth of the Western Zhou Dynasty.
