The heroine, Yin Shiyao's first person name is me, is a college student of traditional Chinese medicine with modern knowledge. She took a 20th birthday photoshoot in the Forbidden City. She accidentally traveled to the Kangxi period and met Yinzhen (the fourth master) who was still Lord Baylor at the time. The brief relationship made me heartbroken. Just when both parties expressed their feelings, the opportunity to return home suddenly appeared. Although the Fourth Master was reluctant to give up, he still desperately helped me return to modern times in order to protect me. After returning to modern times, I still couldn't let go of my love for Yinzhen. Finally, following my obsession, I traveled across time again to find love. Male protagonist: Yinzhen (Fourth Master), the future Emperor Yongzheng. He was a pioneer of thought of that era and a rare "awakened person" in the feudal era. In such a conservative and closed-off feudal society, he struggled to push forward the reform and New Deal, which opened up a new path for the Qing Dynasty to move towards the "Qianlong Era". I once again traveled back to the first year of Yongzheng when he ascended the throne as emperor, and returned to his side. I accompanied him with modern knowledge, and implemented the new reform policy amidst the aftermath of the nine sons seizing the throne and the obstruction of the feudal conservative forces. Please follow the story to experience how the great emperor Yongzheng struggled to push the history of the Qing Dynasty to a climax in the social environment at that time.
