Double-Crossing the Tang Dynasty: I Grew up with Sizi

When Lin Yan was sorting out the cultural relics left behind by his grandfather, he accidentally scratched his finger on the ancestral double-chi jade. A thunderstorm broke out outside the window, triggering the energy fluctuations in time and space, and he was instantly involved in the Jiucheng Palace in Chang'an in the fourth year of Zhenguan. Lin Yan, who had just arrived in the Tang Dynasty, was arrested as an assassin by the palace guards because of his strange clothes and slurred speech. At the critical moment, the 3-year-old Sizi, who was traveling with Empress Changsun, was attracted by the modern candy (with packaging) that fell from her arms. She cried for "sweets wrapped in colorful paper" and unexpectedly came to Lin Yan's rescue. Relying on his historical knowledge, Lin Yan temporarily lied that he was a "hermit in the south of the Yangtze River and moved here due to the war." He gained initial trust through simple first aid knowledge (such as treating minor bruises for Xiao Sizi), and was arranged by Li Shimin to live temporarily in the palace (actually under surveillance). During this period, Lin Yan used the cooling time to return to modern times many times to inquire about court etiquette and historical events in the early Tang Dynasty. At the same time, he returned to the Tang Dynasty with a small amount of modern items (such as sterilized cotton pads, vitamin tablets, simple picture books), and gradually gained Xiao Sizi's trust and dependence. Lin Yan used modern knowledge to help the palace solve small-scale health problems (such as water source disinfection), which attracted the attention of Li Shimin and Fang Xuanling. In modern times, Lin Yan began to organize the information brought back from the Tang Dynasty and wrote relevant academic papers, which was recognized by his tutors. Xiao Sizi suddenly fell ill (such as pneumonia), and the imperial doctors of the Tang Dynasty were helpless. Lin Yan ventured back to modern times to inquire about first aid plans, and returned to the Tang Dynasty with antibiotics (disguised in special packaging). With the secret support of Empress Changsun, he successfully helped Xiao Sizi alleviate his condition. However, his "mysterious ability" also aroused the suspicion of more people...
