The magnetic field was tightening now, twisting the light from those distant stars and bending it straight again. The Interplanetarian reeled like a drunken thing and the great arcs of electric flame looped madly and plunged straight for the field's very heart.
The stars danced weirdly in far-off space again as the Interplanetarian's accumulators lashed out with tremendous force to oppose the energy of the field.
The field glowed softly and disappeared.
"They have us stopped at every turn," groaned Russ. "There must be some way, something we can do." He looked at Greg. Greg grinned without humor, wiping his face. "There is something we can do," said Russ grimly. "We should have thought of it long ago."
He strode to the desk, reached out one hand and drew a calculator near.
"You keep them busy," he snapped. "I'll have this thing figured out in just a while."
From the engine rooms came the roar and hum of the laboring units and the Invincible shuddered once again as Greg grimly hurled one beam after another, at the Interplanetarian.
The Interplanetarian struck back, using radio frequency that flamed fiercely against the Invincible's outer screen. Simultaneously the Interplanetarian leaped forward with a sudden surge of accumulated energy, driving at the star that lay not more than three billion miles away.
Greg worked desperately, cursing under his breath. He pulled down the outer screen that was fighting directly against the radio frequency, energy for energy, and allowed the beam to strike squarely on the second screen, the inversion field that shunted the major portion of the energy impacting against it through 90 degrees into another space.
