"BOOM!!!"
Concrete and rebar flew like artillery shells.
A hole ten meters wide was bored straight through the three-meter-thick wall!
Amid the billowing dust, a terrifying, funnel-shaped maw lined with rings of sharp teeth forced its way inside!
Teeth the size of adults spun madly with an earsplitting grinding sound, wall debris covering their dark gray keratin surfaces.
A Burrowing Earth Dragon.
Its enormous head squeezed into the fortress of Great Xia's Underground City, while its body, over a hundred meters long, writhed violently in the tunnel behind it, pushing forward.
And deep in the tunnel behind it, a densely packed Demon Clan Army advanced greedily.
"Report! A Burrowing Earth Dragon has breached the wall in G4-17 Section!"
Inside the Command Center, a technician shouted hoarsely.
Lin Shigong stared at the hideous, spinning maw on the screen and gave the order without hesitation:
"Detonate."
G4-17 Section.
The instant the electronic signal reached the detonator, Cubic Nitrogen Explosive equivalent to one thousand tons of TNT was activated.
An all-consuming white light erupted in the sealed underground passage!
Confined within the passage, the blast's power repeatedly rebounded and compounded, creating a terrifying overpressure environment.
The supersonic shock wave swept over it at point-blank range.
The Burrowing Earth Dragon, which had only squeezed half its body inside, could not even scream before its meat-grinder maw, powerful enough to pulverize high-strength concrete, shattered instantly!
Its hard keratin teeth burst apart like popcorn, and its flesh carbonized directly into ash in the terrifying heat!
Then.
The incomparably violent shock wave followed the Burrowing Earth Dragon's corpse and surged straight back into the tunnel it had dug!
It was like stuffing a bomb into a gun barrel.
The tunnel's rock strata collapsed completely, mixing with the Burrowing Earth Dragon's body, which the blast had battered
