The sound of Instructor Zhang Chao's footsteps gradually faded at the end of the corridor.
Jiang An stared at the tightly closed office door, his Adam's apple moving with difficulty.
The sunlight outside had somehow been obscured by dark clouds, and the indoor fluorescent lights cast his rigid shadow on the wall.
The thick case file at that moment seemed like a red-hot branding iron, emitting an unsettling aura.
He initially thought that this case might just be a bit more complicated than the ones he had handled before.
With more time and effort, he would eventually unravel it and find the truth.
But, with the grave expression on Instructor Zhang Chao's face when he left just now, and his words left unsaid,
Jiang An realized that the matter was far from simple.
This thick case file was just the tip of the iceberg.
The true difficulties and dangers were too much for even the instructor to describe in detail.
