The Life Radar of the Lv19 Flying Wing Tank was much stronger than Lin Feng's personal Mind Sensing.
With a detection range of five kilometers, it could scan a five-hundred-meter-radius semicircle beneath the surface, allowing for early detection of the Zerg Race's underground movements.
At this moment, numerous Red-Armored Beetle Swarms had already dug Wormholes nearly a hundred meters deep, burrowing from beneath the service area deep into the Wu City District.
If things were already like this where they were, the main defensive line had likely been tunneled through and infiltrated by the Zerg Race long ago.
After all, that was where the main confrontation was taking place.
At least ninety percent of the firefights were happening outside the twenty-kilometer-long fortified line.
Shen Jie had complete faith in Lin Feng's words.
