Kaido, the father-in-law, used monster cells to create the strongest Beast.

Kaido, the father-in-law, creates the strongest Beasts with monster cells. (Author: Greedy for Wine)

Luo Xing transmigrates to the world of One Piece, becomes Kaido's son-in-law, and awakens the Great Inventor System.

Depending on the system level, Luo Xing can create various magical items.

Inventor Level 1: Stretch underwear, plush bra...

Inventor Level 2: Tiger-level Monster Cell...

Inventor Level 3: Demon-level Monster Cell, Triple Gravity Training Room, Basic Time Chamber...

……

Inventor LV10: Flowing Blade, Time Machine, God-level Monster Cell!

...

When a Zoan-type character consumes a monster cell, it's equivalent to everyone becoming an Ancient Zoan, or even a Mythical Zoan!

"Father-in-law Kaido, please consume this god-level monster cell!"

Azure Dragon Form + God-Level Monster = World Destruction!

Luo Xing is going to build the strongest Beast Pirates crew in history!

1. Luo Xing, the Prince Consort of a Hundred Beasts

"I say, Prince Consort Luo Xing, why don't you stay at home and work hard with Young Master Dahe to help Boss Kaido hold his grandson as soon as possible?"

"Why do you have to come all the way to my scientific research department?"

With a burly build, a pipe in his mouth, a gold braid, and a small mustache, Queen the Plague, one of the top members of the Beasts Pirates, was complaining unhappily.

The person he was complaining about was a tall, handsome young man with black hair and black eyes.

Compared to the male members of the Beasts Pirates, who were generally oddly shaped, this young man named Luo Xing was undoubtedly extremely handsome.

"Enough with the nonsense, hurry up and open my lab. Today I'm going to show you something amazing."

"An eye-opener? Your Highness, you haven't invented some kind of underwear that can shrink automatically, or a bra that can enhance breast size, have you?"

"piss off!"

Luo Xing kicked out.

Quinn remained unfazed, his face still bearing that smug grin.

As a Zoan-type Devil Fruit user with the Ancient Zoan type and Brachiosaurus form, and with a bounty of 1.32 billion Berries, this damage is practically nothing to him.

The two entered a laboratory.

Quinn looked around at the strange devices in the laboratory and asked curiously:

"Your Highness, what are all these devices for? I'm supposed to be a scientist, yet I can't understand them at all."

Of course you wouldn't understand; these things are not part of the One Piece world at all.

Luo Xing silently muttered to himself.

He was actually a time traveler.

Because I accidentally dropped cigarette ash on the keyboard, a flash of electricity caused me to inexplicably be transported to the world of One Piece.

What's even more inexplicable is that not long after he transmigrated, he was recruited as the son-in-law of Kaido, one of the Four Emperors, and became the prince consort of the Beasts Pirates.

To this day, he has been with the Beasts Pirates for almost two years as the prince consort.

The initial fear had long since disappeared, and even with powerful figures like the Three Calamities, Luo Xing could calmly chat and laugh.

After getting to know him better, Luo Xing found out why he had been chosen as the prince consort.

The root of the problem lies with Kaido's rebellious daughter, Yamato, who is now Luo Xing's wife.

original.

More than ten years ago, the scene of Kaido executing Kozuki Oden was witnessed by a young Yamato.

At that time, Yamato developed a deep respect for Oden.

Later, she accidentally found Oden's nautical log.

From then on, Yamato's admiration for Kozuki Oden grew ever stronger.

As a result, she actually thought of herself as Kozuki Oden and did the absurd thing of attacking her father Kaido and driving him out of Wano Country!

Poor Kaido, one of the Four Emperors, known as the strongest creature on land, sea and air, even deliberately got captured eighteen times in his youth because he treated the Marines like a canteen, yet he still gave birth to such a bizarre daughter!

It's laughable.

Enraged, Kaido beat Yamato countless times, but Yamato remained unrepentant.

Just when Kaido was racking his brains, Queen, who always had a lot of tricks up his sleeve, gave Kaido a terrible idea—to find a son-in-law.

“Boss Kaido, although you have always raised Yamato as your son, Yamato is still a woman. Women will definitely change after they have a family and children.”

These are Quinn's exact words.

Kaido immediately thought it was unlikely.

Who says women change after having children?

That old hag Lingling has had dozens of children, and she hasn't changed at all.

However, Kaido had no other options against Yamato, so he decided to try anything as a last resort.

Thus, Luo Xing became Kaido's son-in-law and the prince consort of the Beasts Pirates.

Of course, before Luo Xing, Kaido had already captured more than a dozen handsome men, but Yamato didn't even glance at them.

When Luo Xing appeared, Yamato was completely mesmerized.

This shows that

Yamato is not only a silly girl who idolizes Oden based on a diary, but also a lovestruck woman.

Thinking of Yamato, Luo Xing couldn't help but smile slightly.

He was quite satisfied with his cheap wife, whose looks and figure were impeccable.

The only thing Yamato was unhappy about was that he admired that idiot Kozuki Oden.

Kozuki Oden clearly possessed sufficient strength and had a broad popular base in Wano Country.

Outside, there was also the support of two top-tier powerhouses, Whitebeard and Roger.

With such a huge advantage, he was utterly defeated by the newly rising Kaido, resulting in the tragic end of his family being torn apart, his country being destroyed, and his home being destroyed. He's truly a genius!

It wouldn't be an exaggeration to say that Luo Xing looked down on Kozuki Oden.

How could he tolerate his woman admiring such a person?

Therefore,

Over the years, Luo Xing has subtly told Yamato about Oden's folly.

Yamato initially couldn't accept it at all, but gradually, upon closer reflection, she finally realized that what Luo Xing said was correct.

The tragedy of the Kozuki family and the fall of Wano Country were primarily due to Oden's own foolishness.

"No wonder Kozuki Oden was known as the foolish prince; I actually admired him for so many years!"

Upon realizing his past self, Yamato simply couldn't look at his former self the same way.

Without hesitation, she erased all memories of Kozuki Oden from her mind.

Now, Yamato only has Luo Xing in her heart.

As for Kaido, uh, which one is that?

Although Yamato did change after marrying Rashin, as Queen said, he no longer worshipped Oden.

But his dissatisfaction with his father Kaido remains unchanged.

……

……

"Your Highness, what are you thinking about?"

Quinn's shout brought Luo Xing back to reality.

"nothing."

Luo Xing walked to the device in the laboratory, opened the lid, and took out a strangely shaped purple piece of meat.

"The monster cells have been successfully created."

Excitement flashed in Luo Xing's eyes.

He awakened the Great Inventor System at the very beginning of his transmigration.

As the name suggests, it means being able to invent all sorts of amazing things.

Due to system limitations, Luo Xing could only invent trivial gadgets such as underwear and bras.
