At impact the fiercely driven implement flew into a thousand pieces, but such was the power behind it that each piece continued on, driving its relentless way through the tenuous body substance of the erstwhile guard. That body subsided instantly upon the floor, a shapeless and mangled mass of oozing, dripping flesh. Weaponless now, holding only the shattered butt of the ex-guard's trident, Seaton turned to confront the other guard who, still holding Margaret helpless, was advancing upon him, wide-open trident to the fore. He hurled the broken stump; then, as the guard nimbly dodged the flying missile, he leaped to the barred door of the cell. He seized it and jerked mightily; and as the anchor bolts of the hinges tore out of the masonry he swung the entire gate in a full-sweeping circle. Through the soft body the interlaced bars tore, cutting it into ghastly, grisly dice, and on, across the hall, tearing into and demolishing the opposite wall. "All right, Peg, or did he shock you?" Seaton demanded. "All right, I guess--he didn't have time, to do much of anything." "Fine, let's snap it up, then. Or wait a minute, I'd better get us a couple of shields. We've got to keep them from getting those stingarees into us again--as long as we can keep them away from us we can do about as we please around here, but if they ever get hold of us again it'll be just too bad." While Seaton was speaking he had broken away and torn out two great plates or doors of solid metal, and, handing one of them to his companion, he went on: "Here, carry this in front of you and we'll go places and do things." But in that time, short as it was, the alarm had been given, and up the corridor down which they must go was advancing a corps of heavily armed beings. Seaton took one quick step forward, then, realizing the impossibility of forcing his way through such a horde without impalement, he leaped backward to the damaged wall and wrenched out a huge chunk of masonry. Then, while the upper wall and the now unsupported ceiling collapsed upon him, their fragments touching his hard body lightly and bouncing off like so many soft pillows, he hurled that chunk of material down the hall and into the thickest ranks of the attackers. Through the close-packed phalanx it tore as would a plunging tank through massed infantry, nor was it alone. Mass after mass of rock was hurled as fast as the Earthman could bend and straighten his mighty back, and the hypermen broke ranks and fled in wild disorder.
