During the Four Kingdoms era, the increasingly powerful Shang Dynasty showed its ambition to annex the world. The ignorant girl of Wuzhao Kingdom, Princess Zhusha, went to Dashang Kingdom to get married with her father and the expectations of all the people. In order to live up to her high expectations, Zhu Sha aims to become the princess of Prince Bai Ze. However, on the way to the Great Shang Kingdom, it rained heavily and the poor princess was washed off the cliff. Zhu Sha accidentally met Bai Yin, the second prince of the Great Shang Kingdom. Bai Yin is a well-known playboy, and is also nicknamed the "Poison King". He likes to raise snakes and has a tolerant personality. Cinnabar suffers from it. Zhu Sha escaped by chance and finally met her "prospective fiancé" Tai Zize... After Zhu Sha's hard work, she finally won Bai Ze's favor. However, just when she was about to become the crown princess, everyone discovered that she and Bai Yin had "cooked the raw rice into cooked rice"! Zhu Sha was granted a good match by the emperor, and the target was Bai Yin, the "Poison King". The inevitable marriage made Zhu Sha marry Bai Yin. However, at this moment, Zhu Sha discovered a surprising secret - her marriage to Bai Yin was carefully planned by Bai Yin! What shocked Zhusha even more was that she found that she had really fallen in love with the "poisonous" husband. The painful Cinnabar chose to leave. In order to find his lover, Bai Yin, the "Poison King", did not hesitate to raise his troops to besiege Wuzhao Kingdom. When the army approaches the city, where should Cinnabar go?
