Three layers of energy shields, under the continuous artillery attacks of the Klein, had one layer destroyed.
When the Klein's artillery barrage ended and they began low-altitude and ground combat.
The second layer of energy shields showed numerous cracks.
According to the Klein's past experience, Fubei Port Base's defense system should have been completely paralyzed by now.
Now, they just need to harvest the lives of those soldiers who haven't been killed by the blasts.
But this time, the Klein undoubtedly underestimated the situation.
Most of the buildings and facilities at Fubei Port Base had been turned to ruins.
But those things were originally meant to deceive the Klein.
Their recent overwhelming artillery fire did not cause any casualties.
The ten million combat troops of the Black Stone Legion were all in the underground base.
During this time, the rest of the non-combat personnel were almost entirely working in the underground base.
