Chapter 2527: Chapter 2521-patience

In the interrogation room, sun Guodong was holding Zhao Yu's mobile phone and carefully watching a video.

The video recorded the police's search of the mountain, the discovery of the prison built by sun Guodong, and the process of rescuing the imprisoned Bai Wenhai.

It could be seen that Bai Wenhai could still call out his name even after he was rescued. Although his voice was very weak, it was enough to show that his mind was clear.

"You dug more than ten meters deep into the bunker, and even dug out the green mica," Zhao Yu said."You really put in a lot of effort!

"But, you've overlooked some details," Zhao Yu said."You built the prison, so you have to use metal as the cage, and these metals can be detected by ordinary metal detectors!

"With our remote sensing technology, it's only a matter of time before we find your underground cell ..."

Sun Guodong didn't seem to hear what Zhao Yu had said, as he was still focused on the video.
