Perilously Close to Collapse

(Thanks to Chen Xin'er, who is furious with rage, for the reward bonus chapter.)

An Astra Militarum tech-sergeant held a detection device and scanned throughout the ruins of the Hive City.

After a while, he raised his hand and waved toward a large missile transport vehicle ahead.

"Here. There are massive hollow layers underground. Fire the Melta Rocket down from here!"

The missile transport followed his instructions and drove over. Its enormous launch tube rose high, with the rocket warhead aimed at the ground.

After the Astra Militarum sergeant pressed the launch button, the melta nozzle atop the rocket head unleashed a stream of scorching heat.

Soil, rock, and steel all melted away. At the same time, the rocket nozzle at its rear ignited, firing the massive missile underground!

The nuclear warhead flew two kilometers underground before exploding inside a vast hollow layer!

That enormous underground hollow layer had once housed countless humans, but now it had become a playground for the Greenskin Orks.

The Melta Rocket pierced through plasteel concrete structures all the way before exploding inside the hollow layer!

A massive fireball spread outward, instantly killing hundreds of thousands of Greenskin Orks. The explosion also triggered an earthquake, and some unstable Hive City structures collapsed amid the tremors.

The Astra Militarum had brought many such Bunker-Buster Rockets. The Hive City was simply too massive, as were its underground structures, and they had no idea where exactly Three Hands's War Workshop was located.

So they could only overwhelm it with sheer quantity, continuously firing Bunker-Buster Rockets underground!

Elsewhere, inside Three Hands's War Workshop, he and several thousand Mek Boys were performing final maintenance on the Gorkanaut.

His workshop shook violently from time to time, while reinforced concrete structures on the ceiling continuously collapsed.
