At eleven o'clock at night, in the old community near the university town, only a few windows were still lit. Lin Jian rubbed her sour eyes and threw the fifth empty paper cup of instant coffee into the trash can next to her.
The light from the computer screen reflected on her slightly tired face, which was the face of a typical academic worker - her complexion was a little pale due to being indoors for a long time, her facial features were delicate but lacked careful modification, and she wore a pair of black thin-framed glasses on the bridge of her nose, but her eyes behind the lenses were particularly bright due to concentration.
She is compiling a historical document on the operation of the intelligence network during the 1937 Battle of Songhu. This is the third chapter of her doctoral thesis and has been stuck for nearly half a month.
"It still doesn't work..." Lin Jian muttered to herself, tapping her fingers on the table unconsciously.
