Chapter 522 Successful Infiltration_2

In front of this office door, four fully armed guards stood watch. Their gazes were sharp, closely monitoring their surroundings. Not only were they equipped with incredibly powerful individual combat weapons, but they also carried highly sensitive alarms. Should they detect anything amiss, they would press the alarm to issue a warning to the outside.

Besides that, there were two intersecting HD cameras installed at the entrance. Under the mutual coverage of the two intersecting cameras, the weak points of Yan Fei's Combat Armor's optical stealth ability were laid bare. As soon as Yan Fei appeared in front of the cameras, he would certainly be detected by "Future." Observing from two different angles would reveal a significant difference in the color-changing ability of Yan Fei's Combat Armor, which "Future" would detect immediately.
