She looked intently at Ye Shaohua's face, yet she saw not a hint of surprise on it.
"Ye Meng, don't think that by doing this, you can cover up everything from the past." Ye Shaohua narrowed her eyes slightly and lowered her voice.

"The case files of the drug trafficking incident from that year have all been archived in the Police Station.

Ye Meng pursed her lips, the corner of her eye catching Ying Tianyu's expression.
