Chapter 671: Must Become a Star-Grade Martial Artist

The Sand Eagle Headquarters occupied an extremely large area. After leaving the residence that Grek had arranged for Chu Nan and the others, they sneaked three kilometers southwest before leaving the core area of the headquarters.

He turned around and looked at the brightly lit Sand Eagle Headquarters which was still extremely lively and looked no different from a small city. Chu Nan gently exhaled.

The virtual screen of the personal terminal on his wrist finally turned from bright red to green, indicating that Chu Nan had arrived at the area where the signal detection was weak.

According to what Uncle Mu Luo had said when he implanted this anti-monitoring program in Chu Nan's personal terminal, this did not mean that he had completely escaped the enemy's surveillance, nor did it mean that his actions could completely avoid the enemy's surveillance. It only meant that he had more possibility of avoiding the surveillance than others in the monitoring range.
