Shen Qingci, the descendant of a modern ancient martial arts family, traveled through other worlds with his unique skills in medicine and poisoning, but he was reduced to a criminal, and survived a desperate situation in exile. She met Xiao Jingheng, the ninth prince who was also neglected and in deep trouble. The two formed an alliance due to circumstances and established a foothold in the border cold state. Shen Qingci used modern knowledge to improve production and spread medical skills to accumulate people's hearts and wealth.
Returning to the turbulent capital, this "weak alliance" faces the prince's strife, harem plots and court secrets. Shen Qingci used his exquisite medical skills to cure the empress dowager's illness and crack down on the epidemic in the capital. He was extremely talented with his ancient martial arts skills. He also opened a school and built an intelligence network, and his reputation was growing. Xiao Jingheng used pragmatic strategies to win the emperor's heart. He worked step by step in cases of imperial examination fraud and water transportation corruption, and gradually emerged in the battle for the throne. The two went from testing each other to accompanying each other in life and death. They broke through the crisis side by side, and their relationship became deeper and deeper.
When the battle for the throne intensified, they encountered life and death tests such as the crown prince's uterus and the rebellion of the vassal king. Shen Qingci blocked the arrows with his body and Xiao Jingheng protected them with thunder, and finally put down the rebellion and cleared up the government and the opposition. Xiao Jingheng ascended the throne as the empress, and against all opinions, he appointed Shen Qingci as the empress, and implemented the "Two Saints Coming to the Dynasty". The two emperors and empresses worked together to reform the official system, develop production, establish schools, and expand trade. They not only eliminated the remnants of the previous dynasty and stabilized the borders, but also created the "Government of Jingqing" in which the country was peaceful and the people were safe, and all nations came to the dynasty. They turned an alliance that began with interests into an immortal legend that jointly governed the world and left its name in history.
