He Ben Jun

To protect her eldest sister, Yue Ling, the Youngest Princess of Dongyu, was married into the country of Beishuo. However, she married Zhou Shi Yu, the North Prince of Beishuo, not one that was originally intended for. The trip to the Capital City of Beishuo was full of repeated assassinations, but they were saved when a mysterious jade pendant activated the Time Gate, allowing Yue Ling and Zhou Shi Yu to be repeatedly reincarnated and improve themselves from striving to change their destiny to shouldering the national cause. During this time of growth, they fell in love. (Source: WeTV; edited by MyDramaList)
