Qiu Yan Sent a Faint Message

In the 28th year of the Republic of China, the autumn fog in Jinmen was like a cage. Industrialist Gu Yanshen entered "Zhiwei Study" in search of a fatal medical book. However, the owner of the study, Shen Zhiwei, recognized that he was the "old friend" in his brother's photo. A "Surgery" with a secret letter hidden on the title page and information hidden on the back of the paper. He is the "Qingsong" on the underground drug transportation line, and she is going to be the new liaison "Nightingale". What he went to was a narrow escape, and what she was guarding was a point of instant destruction. In troubled times, meeting each other is a disaster. They expressed their love with letters and an inkstone as an alliance. In a world where monsters were rampant, they shared a deep love that was as vague as fire. ——It should be noted that every turn around may be a farewell; every letter may be a last word.
