The lurkers are the key reserves of the Bug Race, lying dormant until needed. However, once the city poses enough of a threat to the mothers of these lurkers, they will call their offspring to resist desperately, and simultaneously summon the nests outside the city to pour forth, all in an effort to save their own lives.
Eternal Night City suffered greatly last time when forced to fight a two-front battle. Now facing a potentially similar predicament, Bai E would not let the same disaster befall himself twice.
Seizing the moment before the city begins a large-scale investigation of the "lurkers," Bai E opts to take out the Bug Nests outside the city directly in advance.
This way, he can ensure that the developments of the battle, both inside and outside the city, remain firmly under his control, and make absolutely certain there are no errors in the rescue plan.
