Chapter 174: Don't You Feel a Bit Heavy?

The woman passed through the surveillance footage on the fourth floor of the office building in a flash, apparently leaving her original position to move toward somewhere.

The faint cold light from the computer screen illuminated Han Fei, giving his face a pale look.

"That woman first appeared on the fourth floor of the office building, and the surveillance footage captured from the video tape is also from the fourth floor."

"Why is she lingering there? Was she a teacher at the school? Or is she trying to find a teacher on the fourth floor?"

Countless doubts sprouted in his mind as Han Fei stared intently at the screen.

The black-and-white surveillance footage seemed to represent another world, capturing the horror within the midnight campus.

After about fifteen seconds, the woman appeared again in the live surveillance video.

This time she had reached the third floor of the office building!
