The engines moaned softly and settled into a quieter rumble as the necessity of supplying the first screen was eliminated. But they screamed once again as Greg sent out a tractor beam that seized and held, dragged the Interplanetarian to a standstill. Craven's ship had gained millions of miles, though, and established a tremendous advantage by fighting nearer to its source of energy.
"Russ," gasped Greg, "if you don't get that scheme of yours figured out pretty soon, we're done for. They've stopped everything we've got. They're nearer the sun. We won't stand a chance if they make another break like that."
Russ glanced up to answer, but his mouth fell open in amazement and he did not speak. A streak of terrible light was striking at them from the Interplanetarian, blinding white light, and along that highway of light swarmed a horde of little green figures, like squirming green amebas. Swarming toward the Invincible, stretching out hungry, pale-green pseudopods toward the inversion barrier ... and eating through it!
Wherever they touched, holes appeared. They drifted through the inversion screen easily and began drilling into the inner screen of anti-entropy. Eating their way into the anti-entropy ... into a state of matter which Russ and Greg had thought would resist all change!
For seconds both men stood transfixed, unable to believe the evidence of their eyes. But the ameba things came on in ever-increasing throngs, creatures that gnawed and slobbered at the anti-entropy, eating into it, flaking it away, drilling their way through it.
When they pierced the anti-entropy, they would cut through the steel plates of the Invincible like so much paper!
And more were coming. More and more!
With a grunt of amazement, Greg slammed a beam straight into the heart of the amebas. They ate the beam and vanished as mistily as before, little glowing things that ate and died. But there were always more to take their place. They overwhelmed the beam and ate back along its length, attacked the screen again.
They ate through walls of force and walls of metal, and a rush of hissing air began to flame into ions in the terrific battle of energies outside the Invincible.
