In the pitch-black cave passage, accompanied by beams of light, a regular sound resonates:
"Beep! Beep! Beep..."
These are the rhythmic sounds emitted by the mechanical dogs when they move, continuously echoing through the cave passage.
Considering the many intersections and the underground environment, they equipped the armed mechanical dogs with wired high-definition cameras.
The members of the Spark Squad followed behind the mechanical dog units, each person holding a device connected to a wired monitoring instrument, watching the road conditions ahead.
Finally, when they reached the original intersection with multiple branches, the mechanical dog unit and the people behind them stopped successively.
Shen Congfei first turned his head, glanced at Xia Wei and the other four official team members, and then looked at the "Little Sparrows" and other reserve trainees.
Since earlier, he had been hearing whispers from the players who were trainees.
