Bang—Bang—
The crisp knocking sounded in the silent and deep corridor.
"Please, come in."
An elderly voice came from behind the door.
YiXiya pushed open the door and looked into the office.
At this moment, the elderly with a head full of silver hair was sitting behind a large sand table, slowly flipping through a yellowed book.
Unlike last time, there was an additional small bookshelf in the innermost corner of the office, which held some books and folders.
YiXiya glanced at the elder and slowly began, "Director, I thought..."
"After the council's decision, all the files of the Night Hawk case will be sealed, and all items and other documents related to Night Hawk have been destroyed,"
he glanced at the folder in the corner of the sand table in front of him, "Tonight, I will package these documents and send them back to the headquarters of the Pollution Cleaning Department with someone special."
