Conspiracy behind a plan

"What are you planning?" Yang Qingyue asked as Tang Ziyi was apparently working out a solution.

Cai Ning and the other officers perked their ears. Xiao Yue had a smile on her face even though no one could see them underneath the specialists' clothing.

"I'm afraid my plan will affect the safety of your officers because I'm going to put my men through the tunnel from every entry and exit." Tang Ziyi explained. "We don't need to waste energy narrowing down the suspects' location."

"Use K9 units to track the scent though it's harder in the sewage but the dogs are trained to do so." Tang Ziyi snapped her finger. "In a matter of time, we find our target. Chief Yang, do you agree?"

Yang Qingyue raised her brow at Cai Ning, asking for an opinion. The vice chief calculated and thought no other options were available. As for risking their officers' lives, weren't Ling Qingyu's guards doing the same?
