"They must have dug tunnels in the city!"
Song Heping blurted out.
If he's not mistaken, the underground of Daguge City has surely been hollowed out by the 1515 armed forces!
They've constructed an intricate network of tunnels!
The bombing on the surface seemed to destroy buildings but was unlikely to harm the living forces hiding in the tunnels.
In fact, these tunnel exits might be scattered throughout the entire city, allowing them to appear out of nowhere anywhere, launching lethal flank attacks and stabs on exposed attacking troops!
This makes a lot of sense.
After all, the reason they could hold out for so long in the Northwest Region against repeated US airstrikes without being wiped out must have been thanks to the city and the tunnels!
That's right!
This is tricky!
Beads of sweat formed on Song Heping's forehead.
