Lin Wu hugged the wall, using stealth to move along until he reached the diamond's left vertex, where he and Little Knife were on the lower-left edge of the diamond.
Shana said, "Don't move." On the screen, two Frenzies were about five meters away from Lin Wu, positioned on the upper-left edge of the diamond. If there were no surveillance, they would likely come face to face as soon as someone showed their head. With a distance of 5 meters, the Frenzy, being Mutant Zombies, could easily detect Lin Wu's stealth.
The two Frenzies turned and slowly walked back. Shana said, "Good, follow them." Lin Wu, dagger in hand, rounded the corner and silently caught up with a Frenzy with his high agility. Grabbing its neck with one hand and executing it with the dagger before carefully laying the body down. Then he quickly pursued the second Frenzy and dealt with it. It was only a pity they weren't elite Frenzies; he only got a complete food pack and 12 pistol rounds.
"Retreat!"
