After a few hard blows, the plastic split, and there was a small explosion as the air within the temple burst through. A gale of escaping gases roared through the little chamber, ripping the rest of the door to shards and hurling the Neptunians right and left. Outside, the flow began to congeal, and a thin snow of liquid air began to fall.
When the blast subsided after several minutes, the Neptunians jumped up, shook off the new gas-snow, and charged through the doorway into the temple itself.
Burl held his Plutonian flashgun at the ready. Inside, they found chaos and disaster. In the great rooms and halls Plutonians writhed on the floors, in the last throes of suffocation and freezing, now that the air had been ripped from their stronghold.
The walls bore brilliant paintings and sharply defined sculptures. Advancing with the ranks of stick-men, Burl caught glimpses of strange scenes on distant planets, of landscapes that must have been Pluto at one time, beneath a double sun that probably was its original parent.
Burl became faintly aware of a distant clanging. Not all the air was gone, he thought; it must be pouring out in slower volume as the pressure diminished. Somewhere an alarm was ringing.
The Neptunians fell behind; he saw now that the floor and walls of the temple were still too hot for them. They began to withdraw, regrouping, blazing away with ice darts and spears at Plutonians who had appeared in hastily-donned space garments.
Burl fired, then plunged on. He had to get to the hall where Russ was imprisoned.
Finally he was out of sight and sound of the Neptunians and their adversaries. Behind him a door swung down. He was nearing the heart of the building now. The remaining Plutonians were sealing it off, rallying for their final defense.
He was now cut off from support. But he still counted on confusion and surprise to aid him. He ran down a long hall to a vast central chamber and arrived a split second before the door slammed shut after him. The museum of galactic life!
It was a huge hall, oval in shape. In its center was a block that might be an altar. Lining the walls on each side, ranging from the great door on the far end to the equally ornate one through which Burl had come, were floor-to-ceiling niches with gently curved, transparent fronts. He could see dark shapes standing motionless within each of these exhibition cases.
