Zhu Tian started by deceiving his father-in-law from the perspective of pirates.

"Hmph! Then I'll use this newly acquired power to beat you up, Father." Yamato took out his spiked club, Ken, covered it with fel flames, and then flapped his huge demon wings, swooping down towards Kaido.

"Thunder gossip!"

"Haha! Good timing, I'll join in the Thunderous Gossip too."

Two astonishing bursts of Conqueror's Haki began to collide, lightning raged across the sky, and a terrifying aura began to emerge.

Two spiked clubs, one large and one small, collided, and red and green lightning began to rage everywhere.

Goodness gracious! This father and daughter are both inhumanly strong! If Kaido were taken to the world of Azeroth, I wonder what level of combat power he would have. Rhodes estimates that he would be no less than a demigod, and might even be able to kill a demigod.

In other words, with Kaido's current fighting strength, after consuming the Fel Blood, he should be much stronger than Hellscream, and may even have the fighting strength of a high-ranking commander of the Burning Legion.

In their first encounter, their basic attacks were surprisingly evenly matched.

"This is the real Thunderous Eight Trigrams. The young master's previous attack was just Thunderous Four Trigrams."

"I really didn't expect that young master Yamato could actually go head-to-head with boss Kaido and not be at a disadvantage."

"This green thing actually caused him to change his form! It's almost like the beastman form of a Devil Fruit," Jack said.

"Not bad! As expected of my son, hahaha! Let's continue." Kaido's body also changed at this moment. Blue dragon scales appeared, and a huge dragon tail and dragon claws began to appear. Kaido directly underwent a half-beast transformation.

"Damn it! Behold my new move, Evil Fire Eight Trigrams!" Yamato spun in the air, covering his spiked club with all his evil energy and his Armed Forces Haki, before swinging it at Kaido's head.

"Hahaha! Take this! Thunder Bagua!" Kaido gripped his spiked club with both hands, covering it with his Conqueror's Haki and Armament Haki, and then swung it towards Yamato in the sky.

A fierce wind howled and thunder roared in the sky, as crimson and dark green energy lightning collided violently.

If this were the old Yamato, she would definitely have been knocked down by Kaido in one blow. But after drinking the blood of evil energy and transforming into her demon form, Yamato actually managed to withstand Kaido's Thunder Bagua.

Chapter 20 Father-Daughter Battle, Conqueror's Haki Enveloping the Body

"Don't underestimate me, Minotaur! Take this! This isn't over yet!" In the sky, the demonized Yamato's facial expression turned frenzied as he excitedly fought his father.

After consuming the evil energy, the ferocity of Kaido and his race was fully unleashed. Yamato, who originally had a relatively good personality, has now become a warmonger.

Or rather, Yamato's personality was originally that of a warmonger, but her father was even more warmonger than her.

Moreover, this was the first time she had the power to directly confront her father. At this moment, Yamato felt her blood boiling, a fervent fighting spirit rising within her, and her Conqueror's Haki had unknowingly made her even stronger.

Two spiked clubs, one large and one small, clashed repeatedly in the sky. Using the demon wings on her back, Yamato skillfully dodged Kaido's attacks.

"Descend the Three Worlds, summon Naraku." Kaido raised his spiked club high, summoning lightning from the sky to attack Yamato.

"Evil Fire Wheel!" Driven by the demonic wings on his back, Yamato's body transformed into a swirling evil energy storm, crashing head-on into Kaido's attack.

Boom! Boom! The sound of violent explosions echoed through the sky. It was as if the night sky had been torn open, and countless red, black, and green lightning bolts began to rage.

"Your strength has increased quite a bit, you foolish son!" Kaido said, placing his spiked club on his shoulder and looking at the panting Yamato in the distance.

Previously, Yamato would be lucky to withstand one of his attacks; after two, he would definitely fall. However, after consuming that guy's evil blood, he actually developed a humanoid-beast form similar to a Mythical Zoan.

His combat power has increased exponentially, his physical attributes have also increased several times over, and he has become extremely frenzied and warlike, something Kaido clearly noticed!

Yamato's eyes were enveloped in a kind of green, malevolent fire. At this moment, although the little girl was a bit tired, she was still full of fighting spirit.

This girl was already much stronger than the Flying Six before, and she could fight Jack the Drought to a draw. In the Beasts Pirates, she was second only to himself, King the Wildfire, and Queen the Plague.

But now, being able to fight to this extent against her own dragon form, this girl's strength is already on par with the other two, and she might even be able to defeat Quinn and Jhin.

The power boost from this evil energy technique far exceeded Kaido's expectations. If he were to consume such a substance and gain the same combat strength as Yamato, then no one in the world would be his match, and Whitebeard would be defeated in just a few moves.

In fact, in recent years, Kaido and Whitebeard have been evenly matched, and Kaido has even gained some advantages in their battles. After all, Kaido, who is recognized as the strongest in one-on-one combat in the world, is no joke.

Whitebeard now needs his son's help to defeat Kaido of the Beasts. If he could increase his own strength, even the entire Whitebeard Pirates together wouldn't be a match for Kaido.

"You damn bull-headed gorilla, don't get cocky. I haven't gotten used to this new power yet, otherwise I would have definitely crushed you." Yamato said, panting heavily in the sky.

"Let me tell you! You stupid little girl, you're not qualified to beat me." Kaido, carrying his spiked club, hovered in mid-air, his feet resting on a cloud of flames, and laughed loudly.

If it were any other Devil Fruit user, they would definitely be at a great disadvantage against Yamato, who can fly, but not me, because I can fly.

Unbeknownst to them, after a battle, Kaido had even changed how he addressed Yamato.

Yamato in the sky let out a cold laugh, brandishing his spiked club, and continued to fight Kaido. The two figures, one big and one small, clashed fiercely in the sky.

Every basic attack from the two was filled with power, a clash between Conqueror's Haki, a collision between Fel Energy and Devil Fruit abilities.

"Ah! You damn bull-headed gorilla, why can't I beat you up even after obtaining this power?" Yamato said as he flew through the sky.

"You stupid girl, let me tell you! The reason you can't beat me is because you haven't mastered the domineering aura enough."

Conqueror's Haki can also be used to entangle, by combining Conqueror's Haki with Armament Haki.

"Concentrate your attack on one point, and don't waste a single bit of your Haki," Kaido said.

"Conqueror's Haki! Conqueror's Haki can also be used to entangle? I see, I see. No wonder your attacks are so much stronger than mine," Yamato said thoughtfully.

Even with the enhancement of his evil energy, along with the evil flames and Armament Haki covering him, he could only barely block Kaido's attacks.

It turns out that this bull-headed gorilla is also imbued with Conqueror's Haki.

“That’s right! But even if you know, so what? Can you do it?” Kaido said.

Conqueror's Haki can indeed be used to entangle, but how many people in this world possess Conqueror's Haki? And even if one possesses Conqueror's Haki, can one actually entangle with it? Can one comprehend this principle?

This is the real key point. Only by mastering the three types of Haki and combining Armament Haki, Conqueror's Haki, and Observation Haki in battle can one truly become a strong person.

"Damn it! Conqueror's Haki is all over me! How do I get Conqueror's Haki to work?" Yamato in the sky exclaimed, clutching his head.

However, at this moment, her mind seemed somewhat clouded, after all, this was her first time receiving fel energy and transforming into a demon form. Yamato's ability to maintain her sanity was already thanks to Rhodes's secret help.

"Alright, silly girl, it's time to end this battle. To be honest, I'm quite satisfied with your performance. You're now a strong fighter on the high seas. Now, here comes my final blow, Gunchari Dragon." Kaido raised his spiked club, Armament Haki and Conqueror's Haki swirling around it with all his might, and struck at his eldest daughter.

He has already tested his daughter's true combat power. At this moment, Yamato, who has undergone the transformation of evil energy, has reached the level of a Yonko vice-president, or even stronger. Even a Yonko-level being would need to put in some effort to deal with his daughter.

"Ahhh!" A scream echoed from the sky.

After a fierce battle, Yamato finally fell from the sky, and her father Kaido emerged victorious.

Upon landing, Yamato immediately fainted and deactivated her demon form. She looked no different from a normal girl, except that some green fel energy patterns appeared on her body, and the two horns on her head had turned into demon horns.

Chapter 21 Drink up! Kaido, this is your destiny.

At this moment, Yamato rolled his eyes, opened his mouth wide, and lay motionless on the ground.

“Even though his strength has increased a lot, the gap between him and Lord Kaido is still too obvious. Young Master Yamato has been defeated once again,” Queen said.

"Hehe! Poor thing, he got beaten up so badly again. I reckon Young Master Yamato will be bedridden for several days again this time," Black Maria said with a laugh.

"No, no, no, everyone, you have a slightly misunderstanding about the power of the Fel Blood. Young Master Yamato's body has already been completely transformed by this power."

"Her physique has improved, and her recovery ability has naturally increased as well. Believe me, she'll be full of energy tomorrow morning after just one night's sleep," Rod said.

He was really excited watching that battle. The high-level combat power in the One Piece world is still quite reliable, although it's not as overpowered as the Dragon Ball world.

But Kaido is considered a top fighter even in the world of Azeroth, possessing powerful Conqueror's Haki, Armament Haki, and the ability to transform into a dragon.

In Azeroth, mortal races, unless they undergo special energy transformations—such as demonization with fel energy, voidification with void energy, or lightforged forms with holy light energy—can only reach the pinnacle of mortal power and will not progress further. (Many people underestimate Kaido's fighting strength in the One Piece world. Kaido is incredibly powerful; in Azeroth, there is at least no mortal being that Kaido cannot defeat with a single blow. The demigods of Azeroth are not particularly prestigious and have been defeated by various characters; one stag demigod was even killed by orcs.)

"This is really exciting! It's like I've just taken another Zoan-type Devil Fruit, right? Can we also transform into that kind of Devil Fruit?" Jack the Drought asked.

His weakness is that he can't fly. I can grow two pairs of huge wings on my back, so I become a flying unit.

"I'm also very much looking forward to it! Young man, when will you come to inscribe the magic circle for me?" Black Maria said.

"I want that power too!"

"Alright, all of you, don't rush. Let me go first, kid. I can't wait. Let's begin!" Kaido said.

“Alright, Boss Kaido, then please take off your shirt, and I will begin the forensic characterization process,” Rhodes said.

"Wait a minute, if this magic circle isn't inscribed, will I completely lose my mind?" Kaido asked.

For some reason, his Observation Haki was always giving him a warning. If he could, Kaido really didn't want to draw this kind of magic circle.

That Beasts Pirates henchman just now seemed fine, except he'd become a bit more violent and belligerent.

“Boss Kaido, you should have already seen what Yamato looks like. After consuming this blood, you will be driven into a rage. And after you consume the Fel Blood, I think even if everyone here attacked you together, you wouldn’t be a match for Boss Kaido. At that time, the entire Onigashima, or even the entire Wano Country, will be destroyed for you,” Rhodes said.

At the same time, Rhodes shut down his mind, banishing all dangerous and evil thoughts about Kaido from his mind and exerting extreme control over his mental power.

There's only one step left to control Kaido, and there can't be any mistakes at this crucial moment. With his top-tier Observation Haki and the ability to foresee the future, Rhodes can only suppress some of his evil thoughts.

“Hmm! Kid, I don’t think I need to inscribe this kind of magic circle. My strength is very powerful, and I’m confident that I can suppress this violent power. I’ve decided not to inscribe this kind of magic circle,” Kaido said.

Regardless of how eloquently this kid speaks, Kaido intends to trust his intuition.

Because his Observation Haki was also at the highest level, not much worse than Lingling's eldest son, and even a bit stronger.

“Boss Kaido, if you insist on doing this, then no problem. However, it would be best to evacuate all personnel, because something very dangerous might happen in a moment,” Rhodes said.

It's alright, I have a backup plan. Kaido, the magic circle that enslaves demons doesn't necessarily have to be imprinted on your body. To achieve this goal, Rod has made many preparations.

"You mean, Kaido will go crazy in a bit?" King the Wildfire asked.

“Yes! That’s for sure. This energy is extremely violent, and Kaido definitely won’t be able to control his rage,” Rhodes said.

"I was prepared, kid. Give me some of that sobering potion you gave me before."

"This potion can enhance my Observation Haki and my mental strength. I'm confident I can control myself," Kaido said.

"In that case, all personnel should evacuate Ghost Island immediately. Are there any special considerations for ordinary members consuming the Fel Blood?" King the Blaze asked, looking at the three mouthfuls of green Fel Blood.

“There’s nothing special about it. Just take a small sip each and share it,” Rhodes said.

"Okay! Then let's take all these things down and distribute them to all the members of the Beasts Pirates later," said Wildfire.

“Wait, wait, save me a small bottle. I want to study this stuff. I’m a top-notch scientist,” Quinn said.

"I understand. Let's go. We'll leave this place to you first. Kid, I'll leave it to you." After saying that, King the Wildfire called to the others, and all the members of the Beasts Pirates evacuated Onigashima.

Soon, only Rod Kaido and the three unconscious Yamato remained on the island.

Rhodes took out some laced sobering potion and gave it to Kaido to drink first.

"Alright kid! Let's get started!" Kaido stretched his body and said.

Rhodes smiled and placed the huge wooden barrel in front of Kaido.

What was a huge barrel to Rhodes was just a beer mug to Kaido.

“Boss Kaido, please don’t drink it all at once. Leave half for the other members of the Beasts Pirates,” Rod said.
