Travel to the Third Year Since the Founding of the People's Republic of China

The modern girl Chen Xingchen accidentally traveled to Wang Mang's new dynasty and was regarded as a "witch" at the beginning. In order to survive, she relied on her chemical knowledge to deal with Chang'an, but she gradually became involved in the secret case of the Shaofu, the copper poison and the clues about her missing mother. What's even weirder is that the "usurper" Wang Mang in the history books actually looks like a man who knows the future.
