Reverting to his male form, Inala inserted a Prana Bomb—filled with Prana—in the rocket's mouth. The rocket's mouth was part of the Spirit Weapon made using his mouth. Therefore, it could crunch the Prana Bomb and cause the fluid within to spill out.
Its internals were pretty much made out of his digestive system. Hence, the fluid was soon transformed into Prana which was absorbed by the pair of lungs at the back.
Through the nozzle, the two lungs gradually began sucking in the air once Inala activated Internal Inertial Gravity throughout the rocket, concentrating their effects within the lungs.
As Prana continued to surge in the lungs, coupled with Internal Inertial Gravity, space began to expand within, causing more and more air to be absorbed and compressed inside. While this was happening, Inala poured all the filled Prana Bombs and Life Bombs into a giant Prana Bomb.
The rocket was mounted on its back, with its mouth within the giant Prana Bomb, allowing Inala to insert Prana Bombs—into its mouth to fuel it—while seated inside.
Attached to the bottom of the Prana Bomb were a pair of wheels, affixed to a simple suspension system. Trailing from the sides were aeroplane wings. Flaps, rudders, and ailerons were fitted in their respective locations.
All of them were Spirit Weapons, allowing Inala to control them individually.
He took a seat and waited patiently in the cockpit. A couple of straggler Slump Lizards attacked the object, but as it was created using Prana Bombs, contact only caused its Prana to be absorbed.
It took ten minutes for air to be compressed to the limit within the lungs. Inala braced himself and activated it, "Here goes nothing!"
Boom!
A powerful thrust of air was unleashed through the two nozzles, causing the vehicle to shoot forth, lifting off in a matter of seconds. Thanks to the effects of Internal Inertial Gravity, Inala didn't even feel the inertial vectors from the launch speed.
"It took off!" He shouted, having turned the portion of the giant Prana Bomb before him translucent, able to see outside now. The Slump Lizards retreated in fear at this mysterious creature, watching it take flight, an unprecedented case in Sumatra.
Unfortunately for Inala, he had been in the air for less than a dozen seconds when suddenly, the wings attached to the giant Prana Egg vanished.
No, they didn't shatter from friction. They didn't fall off due to the Primary Nature of the Slump Lizards. No, it was something grander, and eerie. The wings simply vanished, as if they never existed there in the first place.
The vehicle slammed into the ground and sustained damage in the process. But its insides were unharmed thanks to Internal Inertial Gravity.
Inala rushed out in a hurry and stared at the location where the wings ought to have existed, "What the…"
The location where the wings were attached to the giant Prana Bomb was smooth. Inala frowned, but as he didn't have the time to search his surroundings, he hunted some Slump Lizards and refined their bones into a pair of aeroplane wings once again.
Ten minutes later, the lungs were filled with compressed air. This time, Inala focused on the wings as the vehicle took flight once again, placing all his attention on it. He regretted it immediately after.
A mysterious eye, ethereal in nature, reddish, scaly in appearance, jotted with a million irises. It appeared next to the wings and stared at it.
Cause and effect seemed to have been changed. In an instant, the pair of wings vanished, as if they never existed in the first place. The mysterious eye vanished as the vehicle slammed into the ground.
Inala rushed out and sprinted to the previous crater where the vehicle had first crashed, shocked to see a bunch of Slump Lizard carcasses lying around, "Fuck!"
These Slump Lizard carcasses were supposed to have been strewn around with pieces of their flesh mashed up. After all, their bones were taken out and used by Inala to make the wings.
But now, when he approached a carcass and touched it, he felt the skeleton inside, 'The wings reverted to their original forms, location, and structure. It's as if I never refined them into the aircraft wings in the first place.'
Since it had happened twice, he would be an idiot if he still failed to understand what was happening. Recalling Sumatra Chronicles, he muttered, "It's not that no Pranic Beast can fly in Sumatra. Since they are constantly evolving, they ought to have evolved in the direction that allowed them to fly. Since that means they would become the race that dominates the skies."
Flying was forbidden!
That was an absolute rule placed on the world, possibly by some omniscient entity with the power to alter cause and effect. Therefore, the moment a Pranic Beast evolves to gain a pair of wings or obtains a Nature granting flight, cause and effect would change, reversing their gains.
Thereby, flight becomes impossible. In his case, he was only using his basic abilities to create a thrust. The only item granting flight was the pair of aircraft wings. Hence, they were erased through cause and effect.
Thereby, the bones used in refining the wings returned to the carcass of their original owners, forming their skeleton, even though the Slump Lizards were dead.
That was a valuable lesson for Inala. Had he tried something like that on his own, he himself would have been erased through this mysterious power.
'Wait, how did nothing happen when the 43rd Empyrean Tusk shot us into the sky?' He recalled the moment when he was shot into the sky—within the giant Prana Bomb—by the 43rd Empyrean Tusk.
When the Boar King rushed at him, he caused aircraft wings to appear on the giant Prana Bomb and used it to change his direction of flight. But nothing happened back then, 'So why now?'
He stared at the air slowly flowing out of the nozzle as the space within vanished, realising what was up. "When the 43rd Empyrean Tusk shot us into the air, from the moment we left its trunk, we had begun decelerating. Therefore, that case was merely a projectile shot out with tremendous force. That wasn't pure flight."
He then stared at the nozzle, "But now, when I was in the air, I was constantly accelerating thanks to the thrust. And with the wings controlling the stability, that was proper flight. Hence, the wings were erased."
"But," He frowned and stared at the nozzle, "Aren't they the source of the thrust? Why weren't they removed? Instead, only the wings were targeted."
He thought for a while and eventually figured it out, "I see. It's complicated."
"But I understand it now." Inala grinned, "I can use this against my enemies."
