Chapter 1678 The Big Black Dog

• The human traffickers who even the patrol house couldn't catch were extremely difficult for Yu Sheng and Du Fei to find. After all, these people were highly alert. If caught, they would face long prison sentences, even the risk of execution.
• At first, Yu Sheng wanted to call Xia Feixue for help, considering her position as a captain in the patrol house. Her assistance would make things much easier. However, thinking of the complicated relationship between them, Yu Sheng dismissed the idea.
• Three days after the incident, Du Fei's people finally found a clue. Following the lead, they arrived at a remote mountainous area.
