Traveling Through the Republic of China, Best Friends Work Together to Engage in Espionage

The author is not very good at writing introductions, so you can read two chapters first. Shen Yunjin and Su Wanqing traveled through time. When I woke up, I only had a few French coins on my body, and a pair of jade bracelets on my wrists that I couldn't take off. Later, they discovered that this pair of bracelets can pass things to each other - if you put them in with the other person in mind, they will appear in the other bracelet thirty seconds later.
