There were Mimic Blade Beasts inside the fortress.
When Wu Man uttered these words, Master Wang and everyone else thought they had heard wrong.
How could there be Mimic Blade Beasts inside the fortress?
Residents of the Fortress Era all knew that the fortress had become humanity's last sanctuary for three main reasons.
One, underground fortresses were structurally easier to defend than to attack.
At the very least, it wouldn't replicate the tragic scenes of surface cities being swept over and devoured by Blade Beasts.
Two, underground fortresses could continue to strengthen their defenses by thickening outer walls and arranging underground mine networks, effectively preventing Mimic Blade Beasts from infiltrating.
Three, it was convenient for surface nuclear bombings.
If Wu Man had not sensed incorrectly, and Mimic Blade Beasts indeed appeared inside the fortress, then there were only two possible sources for these beasts.
