Astounding Stories of Super-Science, June, 1930

"You well understand how we do it. Above us, just below the oil strata, is a steel, trough-shaped roof. The oil, tapped from below, drains into these, and then into these pipe-lines. If we were working from above, now, we would run it to a central shaft, and pump it out. We do not want it on the surface, however."

"Then why in the name of hell do you want it?" Asher barked, a tense note of anger in his voice. "And what do you do with it?" These two were humans. At least, they were in man-form, if not in feeling. And the Petrolia could be handled. Asher was getting mad, and his fear ebbed.

"Come." Lee Wong led the way under the pipe-lines, down the large hall. Krenski, his heavy static gun ready, walked at Asher's back. They came out into another cavern that stretched beyond the powerful lights. The sound of their voices echoed like thunder of the drums of Thor, and Asher realized this cavern might stretch away in Stygian blackness for hundreds of miles.

Asher marveled, for the floor of this cavern dropped at least five feet below the level of the control room or incoming hallways, forming a natural reservoir. A reservoir for the big streams of oil that were pouring into it from the pipe-lines.

The rumble of the oil as it came in and splashed out in a never-ending stream, and the rumble of the oil streams above them as the precious fluid flowed down into the plated drain roof, sounded like the tramp of the weary feet of the damned, as it echoed back and forth across the mighty cavern.

"Our storage." Lee Wong stood at the edge and explained. "Also, as you may see, a concentration incubator, or spawning bed and food storage for our Petrolia."

Blaine Asher looked again at the rippling oil at his feet. He choked brokenly and stepped back a pace. For the oil near the bank was alive! It rippled and splashed, teeming with life. By the strange alchemy of breeding in oil and living on oil as man lives on bread, that lake of oil was a mass of growing Petrolia. Millions – yes, countless billions – of them! Hideous, foul Things that would be turned loose with the rest in that nightmare world – that would be taken to other buried worlds to start new races.

"But why – why?" Asher almost screamed the words at Lee Wong.

"Petrolia will be our armies, protecting our underground wealth," Lee Wong answered him. "They will be our faithful workers, under no command but mine. For, even Krenski has not mastered the over-control it takes to handle them!

"Gradually, as happened to the field we are now under, all oil fields will go dry. We will be getting the oil from below, and putting it in storage in mother earth. Think, Blaine Asher, what it will mean!" There was a fanatical light in Lee Wong's beady eyes.

"A world without petroleum is a world without power. No oil for fuel; no gasoline, lubricants or by-products of any sort. No airplanes could fly; tanks, tractors, oil-burning trains and ships; mechanical appliances – nothing could run. We now take the oil from America. Later, when our Petrolia have increased and we have devised means of moving them, we will go to all oil-producing countries.

"We will secrete the oil and paralyze the world. Now, in Russia and China and India, our societies are organizing and growing. They will handle the weakened, powerless nations, and I shall be ruler of the universe, surface and beneath, with Krenski to aid me, you see. It it wonderful, is it not? And, knowing what you do, having seen what you have, could you call it impossible?"

Blaine Asher groaned. It was not impossible, he knew. Unreal; monstrous – but never impossible. A region of hideous Petrolia; a world stripped of automotive and mechanical power, its fuel held in the hands of a few, far underground – it was terrible to think of.

And Asher the only one who knew. The only one who could avert such a thing. The fate of an entire world was in his hands. And he would soon die.

Die? No! Blaine Asher swore silently to himself that no power in existence should keep him from destroying these two fiends. It had to be done!

He dared not fail.

"Wonderful, stupendous thing," he forced himself to smile. "I'd like to grasp the hand of the genius who devised and carried out such a wonderful thing."

He took a step toward Lee Wong, right hand extended, his left slipping toward the pocket where his own static gun rested.

Lee Wong extended his own right band. Something in the chill, flint look of Asher's eyes must have warned him. Even as Asher's fingers closed around his hand, he tried to jerk back.

"Destroy him!" he cried out to Krenski.

Asher dropped to one knee, letting his static gun remain in his pocket. His left hand closed around Lee Wong's wrist as the Oriental tried to pull away. Krenski was bringing the heavy, cylinderlike gun up and aiming it at Asher.

Asher twisted on one knee, his teeth gritted, braced to receive the shock from the gun. He jerked Lee Wong's arm down, heaved and came to his feet. Crying out, arms and legs flailing, the Chinaman catapulted toward Krenski – and just at the instant Krenski fired!

The sickening smell of cindered flesh was in Asher's nostrils as he turned and ran back up the main hallway. He glanced back over his shoulder as he ran, and shuddered at the black mass lying at Krenski's feet. Lee Wong was no more. Wide-eyed, the Russian stared at the thing at his feet. Then, with a fiendish shriek, turned and brought the gun into line on the fleeing Asher.

A crackling charge of electricity singed the back of Asher's head as he dove head first around the corner of the hall into the control cavern. He reasoned that Krenski had sent a full charge after him, and hope kindled higher in his breast. For Asher believed his smaller static weapon was as strong as that of the other. At that, it would be a test, and Asher dared not take chances.

He crouched in the door of another hallway, waiting. Cursing, Krenski dashed into the control cavern. Asher brought his gun up and fired. But even as he pulled the trigger, a long tentacle reached from the dark crevice behind him and jerked his arm. His charge snapped by the Russian, warning the other that Asher, too, was dealing with powerful electric rays that meant death should they touch.

Asher yielded to the tug of the slimy, sulphur-smelling tentacle, letting it pull him into the crevice, the charges of Krenski's weapon crackling by him, leaving his skin dry, and a powdery sensation in his mouth.

In the shelter of the crevice, Asher turned his gun upon the Petrolia that gripped him. The tentacles fell away, fading to nothingness before the charges that showed quivery blue in the dark. Like catacombs, one crevice opened into another. Asher darted into the next crevice and edged cautiously toward the control cavern.

The angry buzzing and snapping of Krenski's weapon caused him to duck instinctively, although no deadly charges came his way.

"Oh, God!" he heard the Russian's high-pitched voice, agonized, wailing, "they're coming in – they're coming in!"

A squeaking and slithering, now greater than ever, rose above all other sounds. And Asher realized what Krenski meant. Lee Wong had said that only he could control the Petrolia. They were swarming into the control room now. That was what Krenski was shooting at.

The squeaking sounds came up the crevice in which Asher was and a cold, clammy sweat broke out all over him. He could blast a thousand of them into nothing. But by sheer force, more body than his light static gun could down, they would overwhelm him.

His mind raced swiftly. He remembered the location, out in the control room, of the cage elevator that ran to the surface. It had not been hurt by the glycerine blast that had trapped Asher. The elevator shaft from the control room was cased clear into the cavern floor, and the blast had not jarred this far.

He wheeled and sent another charge of static electricity into the crevice back of him, then lunged out into the control room. It would be his own weapon against Krenski's, and a chance to gain the bottom of the shaft.

Krenski – piled, charred heaps of the Petrolia around him, which had momentarily cleared the attack – was running across the control room. Like a seething wave, the foul Petrolia undulated from every crevice and hallway, coming in to fresh attack. The Russian, terror lending him speed, raced for the cage at the foot of the shaft that led to the surface. At the same time Asher ran out.

Nearly a hundred feet apart, on opposite sides of the cavern, they stopped. Krenski turned his heavy weapon toward Asher at the same time Asher sent his own gun crackling and snapping out blue, fiery flame.

Side-stepping, now crouching, now dodging to this side and that, they fought their strange duel. Asher's right arm was burned, his hair singed from his head, and his body jarred again and again as Krenski touched him. Krenski, groaning through gritted teeth, suffered burns all over his chest and left leg.

As the Petrolia came on, and the lightning play of deadly electric charges continued, Asher made a discovery. He noticed that the rays, or charges, of the two guns, when they met in mid-air, caused blue flame, and that the charge went no farther.

It did it again. The two charges met, crackled to explosion in the air. Krenski, too, noticed it, and he also noticed that the Petrolia were almost upon them again. Coming on in a wave that could not be hurled back.

He looked at Asher, and met the dare in Asher's eyes. Straight at each other, neither moving, they shot their static charges. Neither would move: it was a challenge from Asher that Krenski had to meet. One of them would have to die before the other would be able to gain the cage in the shaft. There could be no compromise, and only one man at a time could go surfaceward. If they continued to dodge and fight, the Petrolia would overwhelm them.

Power against power, they fought it out.

Asher's finger tightened on his trigger release until it seemed the skin would split; then he caused his hand to tremble just enough to make his electric charges cover the space in which Krenski's charges traveled. Hissing, spitting, flashing explosions, giving off sounds and light like big explosions of flash powder, the charges met.

Asher tingled from head to foot, and thrilled to the very marvel of the thing. Two deadly beams of electricity, holding each other off!

In one long, continuous flash, the contact point of the charges began to shift. Closer and closer, as the force of superior charges cleaved through the other, the contact points neared Krenski. He saw death upon him, for in another instant, Asher's charges would hurl his own bolts back upon him. The smaller weapon of Blaine Asher, attracting more static electric currents by reason of having a small attracting battery inside, where the larger gun of the other depended upon magnets for attraction, was triumphing.

Krenski's mustache and light beard singed and curled. He cried out, stepped back, throwing up his arms as death flashed through his body.

His gun playing about him, Asher raced toward the big valves and gates that shut off the drain of the pipe-lines. Burning, reeking of sulphur and burned leather, the Petrolia vanished before him. But, as he turned, the drainage system that was robbing the field shut off. They had blocked his way again!

Too many to blast away altogether, they pressed in. Asher leaped forward, feet kicking, left fist smashing out, static gun crackling as if to tell him that nothing could stop them. Tentacles gripped at him, the foul, stinking smell gagged him. But the squeaks of the Petrolia maddened him.

"Squeak, damn you!" Asher shouted wildly, kicking, shooting and hitting, gaining toward the shaft. "Squeak – for all the damned Things that ever bred below the earth cannot stop one surface man!"

He burned and fought his way through and jumped into the cage as his gun electrocuted two of the Petrolia that tried to weave in after him. As he slammed the door, Asher was conscious that something was happening. He hesitated, just long enough to see the cavern start buckling and caving. The pressure of the oil, now shut off, was filling back toward the surface, creating a mighty pressure downward. The surface wells would produce man's power-fuel once more.

Asher slammed the door, turned on the power, and the cage shot upward.

A half hour later, those waiting on the floor of the derrick above the hole in which Asher had gone down, started. Asher, burned, wounded, blood streaming from his battered body, staggered in and collapsed at their feet.
