They didn't even use their flashlights. They just stuck a small fluorescent sticker on Xia ruofei's back and pushed forward one by one.
Xia ruofei's eyesight was very good, and he quickly adapted to the sewer environment, so he could easily keep up with Blackie without the need for light. This made Guo Zhan and Tian Feilong secretly amazed. They felt that Xia ruofei's abilities in all aspects seemed to have become stronger after he left the Army.
Blackie walked and stopped. When it was uncertain, it would return for a while to the fork to determine the direction again.
The three of them made many turns in the sewer and advanced for about seven to eight hundred meters.
The Special Forces were usually very sensitive to directions. Although they had turned around a few times in the dark, they could still roughly tell that they were about 500 meters Southwest of the laboratory building.
Finally, Blackie came to a stop and whimpered a few times at Xia ruofei.
