The cramped compartment was hardly accommodating to these enormous armored units.
But that was no great problem.
The Executor tank's massive turret began to operate, loading the high-explosive ammunition stored inside it beforehand.
The thick gun barrel tilted slightly.
Then a tremendous explosion erupted along the side of the cargo hold.
Whole sections of the cargo hold's wall vanished, turning into fragments that flew everywhere.
The other interlocking ship structures beyond the wall were blasted into debris as well.
A faintly silver, dustlike substance spilled from the gaps in the Executor tank's turret, and some of the drifting fragments nearby soon vanished into thin air.
It was like scraps of paper catching fire and crumbling into fine ash in midair.
That silver dust was a Nano-Swarm.
As soon as ammunition was expended, these microscopic robots gathered material and reconstructed a shell to replace it.
The remaining metal was immediately used to repair the tiny scratches on the hull.
Even scratches so fine they were almost invisible to the naked eye.
Drawn by the explosion, the Ultramarines swarmed into the compartment Octopus had torn open, and almost all of them froze in stunned silence.
These tanks, far larger than the Emperor's Baneblades, radiated a deadly menace.

A tremendous roar followed.
The overlapping layers of ship wreckage and rock fragments were punched clean through.
Within the enormous passage, a route opened straight into space.
The air inside and the
