Chapter 488: Confirming the Plan

"Do you have any way of locating the sewage pipelines of the underground prison?" Luo Zheng asked with a stern face.

"I've tried but found nothing," Shadow said with a wry, helpless smile.

"Expand the search area. Isn't there a river about ten kilometers from here? Could it be connected directly to the river? With so many people in the underground prison, how do they dispose of domestic wastewater? I refuse to believe they don't have underground pipelines," Luo Zheng seriously commented, his expression as grim as iron, a trace of anger flickering through it.

"A river more than ten kilometers away?" Shadow's eyes lit up, suddenly full of thoughts, and said, "How about I go and have a look right now? There's no time to lose. Given there's a mole, our location is likely compromised, and we must act fast."
