This article is a fan novel of the TV series Sparrow. The main story line is similar to the original work. It tells the story of Chen Shen, an agent of our party who has been lurking in the Operations Department of the Wang Puppet Agent Headquarters for a long time, constantly resolving crises, and finally obtained the Return to Zero plan. This article is a serious article, and the author himself has no CP preference, so just ignore CP. . . . . . As for whether the article is BE or HE, it depends on the plot development of the article, and it is initially drafted as BE. This is my first time posting, so please be patient.
