Yang Qiu, who failed in his first rebirth, was reborn again to the body of Yang Qiu, the emperor of the Sui Dynasty, who was about to perish. Compared with the first time, this time he unexpectedly obtained the system of having many children and many blessings. At the beginning, he was forced by the system to have a relationship with the national saint Xiao Longnu. The queen of the harem was the ruthless Wu Zetian, the concubine was the Baiyue saint Yan Lingji, the personal maid was the Han spy Diao Chan, the beauties in the harem included the Luowang assassin Jing Niu, and Jiang Yuyan, who was killed to the point that only the name of the play was left. There was also a queen mother Xiao Meiniang and the imperial concubine Lu Zhi above him. Because the original emperor Yang Qiu took away Chen Yuanyuan, he angered the border guard of the Great Sui Dynasty, Wu Sangui, and joined forces with Huang Taiji to attack the Great Sui Dynasty. Yang Qiu, who was killed last time when he gave up the throne, decided to fight to the death.
