Any fish that hunted other fishes were classified under this category. But the ones summoned by the Helper Whistle were at least one to two meters in length and had a vicious nature. On top of that, it was calculated based on their ability to resist a wave.
In other words, that meant only fishes capable of killing at least three Neon Radiance fishes were classified as the predator fishes summoned by the Helper Whistle.
With that, Gajor blew a hundred of them ten times each, causing the ocean water to dim a little as a thousand predator fishes appeared, swimming through the waters as they headed straight towards the Checkpoint Turtle.
Using the Helper Whistles, that was the command Gajor gave them. A Helper Whistle worked on chance. Only the closest predator fish would be summoned. And by summoned, it wasn't as if they would be teleported.
They would simply be called forth. The closer they were, the faster they came. Since he had called forth a thousand predator fishes, they arrived in numerous batches, splitting up as they began to attack the Checkpoint Turtle.
The breath blockers—the tablet walls—blocked all of the Checkpoint Turtle's breath attacks while the torpedoes continued to drill into its body. Even though its body was tremendously tough, after drilling continuously, they were beginning to pierce through it.
They hadn't aimed at its shell. Gajor and Gehen were knowledgeable about just how ridiculously tough the Checkpoint Turtle's shell was. Even its muscles proved to be tremendously tough. As for the shell, they could drill it for an entire year and still fail to penetrate it completely.
First of all, they didn't have the proper tools to damage it. And secondly, the shell absorbed the healing properties from the ocean water. Therefore, it was capable of healing the damage inflicted on it.
So, attacking the shell was perfectly useless. Moreover, even its body was the same, capable of healing by absorbing the healing properties in the ocean water. Moreover, it was able to condense all the healing effects in a damaged part.
Since it was stupendously huge, resembling an island, the amount of healing effect it could absorb was nauseating to drill through. Despite everything, they continued to attack it.
The greatest damage dealer to it was the pirate ship that rammed into it from time to time, jerking it completely. This caused it internal damage while at times causing it to shoot breath attacks on the pirate ship.
Gajor and Gehen were happy whenever that happened. That was because even they knew the ship's hull wouldn't fall apart that fast. It would be able to bear at least forty to fifty attacks before even beginning to crack.
Plus, it took almost a minute per breath attack.
The predator fishes entered the gaps between its shell, biting into its flesh. A torpedo retreated, revealing the hole it had drilled through. A group of predator fishes hurriedly swamped the area, biting through the exposed flesh.
Just the sheer nutrition within it caused the predator fishes to enter a state of frenzy, drilling through it in an effort to devour more.
The Checkpoint Turtle flailed its limbs, failing to hit anyone as it was just too slow. As for its breath attacks, they were being defended by the tablet walls. Though at times, they failed to completely negate the damage and caused some casualties. In any case, it didn't matter on the grand scale of things.
Neither of the twins cared about the losses. In their minds, all losses were recoverable.
"Time to send in the big one now." Gehen laughed as a large space was opened in the ship's front. Exiting it was a torpedo ten times the size of others. There were four Motor Fishes just to propel it forward and another four to spin it. All of them were adults.
The moment they appeared, the Checkpoint Turtle noticed them. But, when it targeted them, the pirates controlling the tablet walls desperately moved forth to defend. More than half the pirates had suffered serious injuries now.
But now, that didn't matter as they persisted.
The Checkpoint Turtle condensed another breath attack. This time though, it didn't unleash it, instead storing it and compressing it further. Upon seeing it, Gehen knew that the situation had turned dangerous.
He immediately summoned all the fishes under his control to move forth, forming a large spherical school in the water, heading towards the Checkpoint Turtle's mouth. As for the two massive torpedoes, they spun ominously in the water, traveling at insane speeds.
Right when the Checkpoint Turtle opened its mouth, the two of them pierced into either side of its shoulder, targeting the point where its neck touched its body. The insane revolution it possessed caused it to readily drill into the Checkpoint turtle's flesh, drawing out copious amounts of blood.
As the Checkpoint Turtle's mouth opened, a sphere of air exited, looking almost no different to the bubbles from before. But this time, it seemed slightly heavier. On top of that, it didn't blast forth, moving slowly as it arrived before the school of fish, breaking apart.
For a moment, the ocean water seemed to have frozen over as everything seemed still. But immediately, a vortex formed in the center before a powerful shockwave blasted forth, attacking everything in its path.
It hit the pirate ship, sending it flying back a little. As for the pirates, they turned into a sea of blood. Most of the torpedoes had been destroyed, the Motor Fishes within, dead.
Gehen quickly got up and ran through the ship, soon exiting it as he was only able to see a sea of blood. His brother had already been floating outside. The two arrived within the ship and looked at each other, looking at the confusion and fear in the eyes of one another.
Gajor asked, "Is it dead?"
Gehen shook his head as he replied, "It's still going strong."
"Damn it. I guess we have no other choice but to go all out," Gajor cursed. "We might be able to replenish the pirates within a couple of years. But, we won't be able to replenish the Motor Fishes that quickly."
"But once you get that, we'll have more power. We can slowly accumulate everything back once again," Gehen said.
"Fine. What you said makes sense." Gajor nodded, commanding all the pirates to head out, "It's almost dead. One more push. The one that contributes the most would be directly supported with powerful passive abilities."
All the remaining pirates exited the pirate ship, swimming towards the Checkpoint Turtle. The remaining torpedoes were also launched as the pirate ship accelerated towards the Checkpoint Turtle, ramming into it.
The two monstrous objects moved past the sea of blood as Gehen was able to notice the two torpedoes lodged deeply into the Checkpoint Turtle's neck. It seemed the force from its attack had caused them to be lodged deep into its neck, preventing it from healing itself.
Moreover, there still seemed to be around a dozen predator fishes that were alive. They were the ones that had penetrated deep into the Checkpoint Turtle's flesh and had avoided the shockwave.
Gehen rammed the pirate ship into the Checkpoint Turtle continuously while Gajor commanded the pirates to attack accordingly. The earlier attack had caused all four of their tablet walls to be sent flying. When the momentum died, they sunk to the depths of the ocean.
Thankfully for them, the injuries in its neck prevented the Checkpoint Turtle from unleashing strong breath attacks anymore. The ones it unleashed, although terrifying, weren't at the previous levels. The shockwaves didn't directly kill them.
And with the Water Essence healing them, combined with the fact that they were surrounded by water, the pirates persisted. The battle continued for three more days when the last of the pirate perished. None of them had escaped because the closer they got to killing the Checkpoint Turtle, the greater they were enveloped by greed, wondering if they would be the lucky ones to obtain its ability.
Eventually, only Gajor and Gehen were alive. Without saying anything, they sped through the waters, intending to deal the final blow to the Checkpoint Turtle. At present, its neck was almost snapped as it was oozing out blood.
It was on the verge of death. Upon seeing it, Gajor carried his blade, expressing his greed as he sped forth with his maximum speed. Summoning all his strength, he hacked on the tethered portion of the neck, barely causing a dent.
Gehen had arrived before him, positioning himself on the other side as he began to hack into it. To prevent being stabbed in the back, the two faced each other and continued to hack into the Checkpoint Turtle's neck.
And when it seemed like it was about to die, Gajor raised his blade high up, condensing all his strength in it as he brought down his blade, pausing abruptly as he noticed a blade peeking out of his chest.
His first thought was of Gehen betraying him. He looked at his brother, noticing the shocked look on the other party, suffused with anger and disbelief. Gajor turned around, wondering if there was any other pirate that had survived and had stabbed his back, only to see a Motor Fish hatchling holding a blade.
His eyes widened as he mentally sighed, watching a sword pierce his neck. It was Gehen.
After killing Gajor, he didn't even waste another second on him as Gehen hacked with his sword, dealing the final blow to the Checkpoint Turtle.
