The most unbearable thing is its unparalleled tunneling method.
Don't be fooled by their body length of over two hundred meters; their agility underground is unimaginable.
They can reach speeds of over 250 kilometers per hour, comparable to many small orbital vehicles.
Additionally, the tunneling worms have a peculiar biological magnetic field within them.
This magnetic field cancels out most underground detection equipment scans, making them very difficult to deal with.
So in the eyes of the Guleng Star Federation people, this creature is practically a phantom demolition worker.
There are frequently buildings damaged by tunneling worms, causing tens of thousands to suffer from disasters.
With no other choice, to resist the invasion of such exotic beasts, the Federation can only fortify the corridors on the city's edges.
Strengthening the foundation as deep and as firm as possible to block them from underground.
Fortunately, these monsters don't favor human steel buildings.
