Discovering a Problem

There were several surveillance videos on the USB drive.

Yu Su looked at it quickly and quickly discovered the problem. She realized that two videos were missing from these surveillance videos.

One was at nine o'clock in the morning, and the other was at three o'clock in the afternoon. The time was about two minutes.

There must be a problem if video clips of the same length were missing.

Yu Su said, "These videos are all missing two time periods. He Wan must have been taken away during these two time periods."

"Huh?"

He Jun asked in surprise, "At that time, our colleague from the Internet Technology Department also came over. He said that there were no traces of edits on this video. Then where did the two time periods that disappeared go?"

The video had not been edited, but part of it had disappeared. Why did this sound so strange?

Leng Yan also looked at Yu Su in confusion.
