Lin Yun was taken aback: "Your Majesty, what is this...?"

Emperor Yongzheng smiled and said, "Yun'er's talent should not be buried. Since you wrote this book, it is natural that your name should be on it."

Lin Yun was touched, but also somewhat worried: "As a concubine in the harem, if I were to publish a book under my own name, it might attract criticism."

Emperor Yongzheng grasped her hand, his gaze unwavering: "With me here, no one dares to speak out. Moreover, your scholarship benefits the entire world, which is a blessing for the Qing Dynasty."

Lin Yun said no more and nodded gently.

Emperor Yongzheng then ordered that "Introduction to Chemistry" be printed and distributed to schools in various provinces.

The book caused a sensation among students as soon as it was published.

Everyone wondered who this "Lin Jia" was, that she could write such exquisite works.

Some say she was a reclusive woman living in the mountains, others say she was a scholar who returned from overseas, and still others speculate that she was the wife of a certain minister.

Until one day, a man whose daughter was studying at Mingde Academy casually mentioned, "My younger sister said that the Imperial Concubine once talked about the contents of the book when she was teaching at the academy..."

Everyone then realized that "Lin Jia Shi" was actually the current Imperial Concubine!

After the news spread, it sparked heated discussions both in and out of government.

Some admired the imperial concubine's talent, while others secretly grumbled that the empress's interference in politics was against etiquette.

But more than anything, there was curiosity and admiration for this imperial concubine.

Later, people gradually learned that when the imperial concubine entered the palace in her early years, she had been promoted to the Plain Yellow Banner of the Han Army and changed her surname to Linjia.

Her scholarship and contributions have long transcended the boundaries of the imperial harem, becoming an important force driving the progress of the Qing Dynasty.
