The insect army's lair, the "Insect Nest," was not built aboveground but hidden beneath the earth.
Before the insect army went to war, they had dug out a massive underground nest spanning hundreds of square kilometers, easy to defend and hard to attack.
Moreover, to prevent smoke suffocation and flooding, countless tunnels had been dug around the Insect Nest—at least a thousand of them, densely packed like a beehive.

Aside from several main troop passages and secondary supply routes, many of the tunnels were actually traps or dead ends.
If the little blue people broke in and split up to enter these tunnels, they would either end up trapped in dead ends or stumble into traps full of poisonous gas. It would be extremely troublesome.
Xiao Tian, the Skrull Gary, and the black rhinoceros-like magic beast had arrived at the entrance of one such tunnel.
This tunnel was neither a trap passage nor a dead end, nor was it a marching route for the insect army. It was an abandoned tunnel that had once been used but was now deserted.
