Final Result

In the gloomy space, the emaciated Kaido lay on the ground, his face blank, his lips cracked, his beard unkempt, and his eyes sunken.

That once strong, almost deformed physique, with muscles that inspired fear, has now shriveled up, looking as if a layer of skin has been pasted on top of the bones.

"That damned Pops, could he be dead already?"

Standing on the monitor outside the prison, looking at Kaido lying in the gray space, Yamato couldn't help but ask with some concern.

"Don't worry, I have his physiological monitor here. He just looks a bit miserable right now, but he has actually used the Life Return to suppress his energy consumption to a minimum. He is definitely not as weak as he appears on the surface."

"If you don't believe me, go in now, and he can fight you for dozens of rounds!"

"Uh... is that so? As expected of Pops, he really is cunning and treacherous!"

Yamato's words made Kozuki Hiyori, who was standing next to her, want to cover her face. She even wondered if Kaido had done too many bad things, so God sent down such a daughter to punish him.

Vegapunk stroked his chin, looked at Kaido lying there, and estimated that it would take a little too long to completely exhaust Kaido to the point of near death.

Even with the harsh conditions in that space, coupled with the lack of water and food, Kaido could probably survive for three months!

If it were a normal deserted island, without water or food, Kaido could probably survive for half a year!

After all, people in the Pirate World are not as fragile as ordinary humans, let alone monsters like Kaido.

"I don't have time to waste with him. I'll send a few advanced mecha warriors to fight him! Given his current condition, he'll probably be finished by the end!"

In the end, Vegapunk made his decision. Hearing what Vegapunk said, Yamato excited, gripped his Spiked Club tightly and asked with a fervent expression:

"Can I go too? I've wanted to defeat this damn Pops for ages!"

Vegapunk glanced at Yamato and thought, "Hmm, case closed. A classic father-son relationship in the Pirate World, definitely related by blood."

But in the end, he shook his head:

"I advise you not to go. People are capable of anything when they're starving, even cannibalism! That's why I only sent the robots..."

Even if Kaido doesn't have gluttony like Big Mom, it's hard to say whether he might treat his daughter like a snack when he's starving. Vegapunk doesn't plan to let Yamato try it out.

Upon hearing this, Yamato shuddered and obediently fell silent.

In the hazy space, a strange Uzumaki suddenly appeared, and a moment later, a tall robot emerged from it.

With its golden armor, a helmet resembling a Tyrannosaurus Rex, sharp claws gleaming with a cold light, and a nimble, streamlined body, it is none other than Vegapunk, one of Vegapunk's three great mechanical war WarGreymon!

Kaido, who had been lying on the ground like a skeleton with a weak breath, suddenly let out a long breath. A white column of air, like a long dragon, gushed out from his mouth and nose, stirring up a small storm in the gray space.

With this deep breath, Kaido's originally emaciated body swelled up as if inflated. Although he had not returned to his original peak condition and looked very thin, he was completely different from his initial skeletal appearance.

His previously blank and lifeless eyes gradually became sharp and bright. However, Kaido looked around and then his expression changed when he saw WarGreymon. His face turned dark and he slammed his fist into the ground.

"Damn it... they actually sent a robot to fob me off?"

Most importantly, robots aren't as accommodating as humans. Even if I wanted to escape from this horrible space, threatening the robots would be pointless.

WarGreymon didn't care about Kaido. Its eyes lit up with a blood-red light, its energy surged, and a pair of sharp claws came crashing down on its head.

"Just a mere robot, how dare you underestimate me!"

Kaido roared, and because he was unarmed, he clenched his fists, transforming into a half-dragon, and threw a punch.

With a thunderous boom, the fist, wreathed in Conqueror's Haki, slammed into WarGreymon's chest and abdomen, sending the terrifying fighting machine flying. However, WarGreymon's sharp claws also slashed down, leaving three deep bloody gashes from Kaido's shoulder to his chest.

Even with the simultaneous protection of incredibly sharp dragon scales and Armament Haki, it could only barely defend against the double claws enhanced by powerful high-frequency vibrations and the nature transformation of Lightning Release Chakra Nature Transformation.

The pain in his shoulder did not shrink Kaido; instead, it fueled his ferocity. With a series of maniacal laughs, Kaido transformed into a Giant Dragon, unleashing a terrifying burst of dragon fire that blasted towards the WarGreymon that had been sent flying.

An Uzumaki instantly appeared in the raging flames, absorbing all the flames completely. WarGreymon emerged from the vanished flames with a cold and tyrannical demeanor.

The two fist imprints from Kaido's attack on his chest and abdomen have faded considerably thanks to the restorative properties of the high-quality Memory Metal.

With a slight narrowing of his eyes, Kaido transformed into a blue dragon, immediately understood that he absolutely could not engage in a prolonged battle with the mechanical monster before him. Possessing Memory Metal and being a machine itself, the mechanical monster could fight indefinitely until its energy was completely exhausted, unless it could destroy WarGreymon in one go.

The energy generated by nuclear fusion is so great that even if Kaido himself died of old age, the energy in WarGreymon's body would probably not even be a third of what it used to be. Even the tanky Tenten in the Pirate King world who fight for days and nights every day would have to admit defeat in comparison.

Having understood the current situation, Kaido did not hesitate. He summoned lightning and flames to wrap around his body, then transformed into a half-dragon and roared as he slammed down!

WarGreymon remained silent, raised its hand and unleashed a Gaia Energy Cannon, then leaped into the air, following behind the energy cannon as it charged towards Kaido.

Three hours later.

"Huff... Damn Vegapunk!!"

Kaido, his body covered in charred and bloody marks, and even a faint smell of meat emanated from him. He roared angrily.

The originally gray space is now pitted and uneven, with some places even flowing with liquid like lava, and other places turning into the color of black glass.

He tore off a piece of charred flesh from his own body, threw it into his mouth, chewed it a couple of times, and at the same time, Kaido's muscles contracted, suppressing the blood vessels and wounds to prevent more blood from flowing out.

There's no food in this space right now. WarGreymon is made entirely of steel, so Kaido definitely wouldn't dare to bite into it. Naturally, he can only gnaw on his own flesh.

As for WarGreymon, which originally fought Kaido, it has now been reduced to pieces and dismantled into this state. It is clear that even Memory Metal cannot restore it.

Fortunately, WarGreymon's AI program had already been uploaded to the Quantum Brain, so dismantling its external body was meaningless; Vegapunk could easily create another one.

The miniature nuclear fusion reactor, which served as the energy center, was also intact. It possessed Observation Haki at the level of Future Sight, Kaido could fully sense the terrifying energy inside the reactor.

Even if Kaido were at his peak and defending with all his might, being hit by that thing would probably take away half of his life, let alone in the current situation, so of course he wouldn't dare to destroy it.

Although Kaido ultimately won the battle, Vegapunk's losses were negligible, or even nonexistent, while Kaido was not only severely injured but also completely exhausted.

At his peak Kaido wouldn't have been so badly injured when defeating WarGreymon, but after being starved for so long, it's already quite an achievement that Kaido was able to win; we can't expect more from him.

However, after Kaido roared twice, he also seemed to be running out of energy. He had been using Life Return conserve his strength, and he might have been able to last for half a year in the Gray Dimension. But now that he had fought WarGreymon, with his strength completely depleted and his body seriously injured, he had little hope of lasting another three to five days!

For a moment, even a hero Gouketsu tyrant like Kaido felt a sense of despair.

"That was a fantastic fight. Your Pops really did have a trick up his sleeve. Good thing you didn't go in!"

After watching Kaido tear WarGreymon apart, Vegapunk pondered his next plan to improve WarGreymon and then spoke to Yamato beside him.

"How much longer is Pops going to be locked up? I think he's about to give up. Why don't I knock him out and bring him out?"

At first, Yamato was a little scared when she saw Kaido unleash his berserk mode and tear WarGreymon to pieces, but now that she sees Kaido looking seriously injured, Yamato can't help but feel a little eager to try again.

The day has come when I will overthrow my Pops and finally take control of my own destiny!

Vegapunk gave Yamato a subtle look. It seemed that even without eating the Dog-Dog Fruit, this guy still had the personality of a purebred husky...

However, Kaido is truly exhausted now. Even if Yamato were to come, there probably wouldn't be any problems. Although she seems to have a silly personality, if Yamato were in good condition and not restricted by Sea Stone Handcuffs, she could Yamato own against Kaido for a while.

Since that's the case, Vegapunk will naturally grant his subordinate Yamato's request. After all, given Yamato's personality, he won't kill Kaido; at most, he'll give him a concussion.

A disheveled Yamato, dragging the sprawled Kaido, finally walked out of the prison.

Even Kaido was on his last breath, he still possessed a powerful burst of energy, much like Whitebeard Marineford War, only not as sustained.

Yamato rushed in excitedly, intending to beat up the wounded, but he clearly suffered a Yamato loss. However, after a round of outbursts, it was obvious that Kaido couldn't hold on any longer, and that's when Yamato and pulled him out.

Looking at the bloodstains left on the ground, Yamato clearly showed no mercy. Kaido was truly and completely unconscious, or perhaps it would be better to describe it as being in shock.

"Very good, send this guy to Laboratory 15! He's a very important experimental subject."

"Oh right, before that, give him an injection of Concentrated Sea Stone Factor Radiation Agent, so he won't escape!"

Concentrated Sea Stone Factor Radiation Agent is hundreds of times more effective than ordinary Sea Stone. To date, any Devil Fruit User test subject under Vegapunk's command has lost all their strength after just a little bit of it.

Even if Kaido is a bit difficult to deal with, a direct injection would be enough to break down all his resistance.

Finally, I have perfect material for my clones. Although I had Kaido's body material, those materials have an expiration date. If I clone again using a cloned body, the quality will drop significantly.

Now things are much better; we don't need to worry about high-quality materials anymore. From now on, the Steel Legion can be used as cannon fodder, and high-ranking soldiers can be entirely replaced by these clones of Kaido.

Even without any Haki or training, Kaido's clones would at least possess combat strength close to that of Marine Vice Admiral.

Even if Kaido isn't as monstrous as Charlotte Linlin, he was still a monster who became the strongest warrior in the Vodka Kingdom at the age of ten. His minimum standard is there, so he can't be that bad.

In the following months, Vegapunk began to consolidate the Beasts Pirates that he had absorbed.

They re-optimized and integrated their robot Combat Program, and used cloned Kaido flesh to fill the three dragon beasts, giving them the ability to autonomously refine Chakra and even use Armament Haki, further enhancing their ultimate combat power.

They gathered up the artificial Devil Fruit User under Kaido's command and made arrangements for them. Some were recruited into the Umbrella Corporation, some were put into Wano Country, and some were scattered outside to serve as pirates and external forces.

Among the high-ranking Beasts Pirates, those who were willing to surrender were recruited as henchmen and directly controlled by Kotoamatsukami, while those who were unwilling were simply treated as experimental subjects. Those who could withstand Kaido's attacks were all physically strong and could be considered excellent experimental subjects.

Vegapunk has already mined most of the Sea Stone Mine. Machine mining is much faster than manual mining. If the Sea Stone Mine in Wano Country hadn't been so enormous, it would probably have been completely mined out by now.

With the current reserves of Sea Stone, manufacturing various Sea Stone weapons and arming a million-strong mechanical army is not a big problem. They can also manufacture more products such as Devil Fruit Ability Disruptor and Concentrated Sea Stone Factor Radiation Agent, thus fully achieving Vegapunk's strategic goals.
