Thousands of years later, the Silla kingdom established by wizards came to an end, which was the real era of the virgin queen. Years of war have brought Silla dynasty to the brink of extinction and the country into turmoil. Fei (Zheng Junhao), an important general of Silla court, has made numerous meritorious military service for the dynasty for many years, and is appreciated by the court and the true saint queen (Jin Huili).
After countless wars and killings, Fei He Lang was not proud of his arrogance, but was immersed in deep remorse. Now, his only hope is to take off his military uniform and live in seclusion in Shan Ye with his beloved woman and civilian woman Ziyunbi (Jin Xiaozhen) to enjoy his old age.
The minister of the DPRK wanted to usurp the throne, and when he learned that the queen had a special liking for Feihelang, he secretly sent court guards to kill Ziyunbi, causing the illusion that the queen ordered the killing of Ziyunbi and provoking the relationship between monarch and minister. Ziyunbi drew Shenmu Excalibur to defend herself on the way to be hunted. In the end, Ziyunbi, who had no way out, jumped into the Millennium Lake soaked with Ota people's resentment and blood.
After the Excalibur pulled out the seal and unsealed it, the ghost of Ota, the leader of the Oota people who hated Silla Dynasty, attached hatred and resentment to Ziyunbi who jumped into the lake, and Ziyunbi was reborn. After the rebirth, Ziyunbi added all the hatred to Silla Dynasty and started a series of revenge. She no longer knows the Fei He Lang she once loved. Facing the woman he once loved, Fei He Lang had to raise his Excalibur in order to be responsible.
