One Piece: Kaido's adopted son, starts with the Eight Gates Formation.

A new world, a certain sea area.

The flagship of the Red-Haired Pirates, the Red Fox.

A banquet was being held on the ship, and Shanks, as always, was raising a bottle of wine and drinking heartily with the crew.

"Captain! Captain! Look at this!"

Yasopp came running over, waving a newspaper and shouting.

"Oh? What's got you so excited, Yasopp?"

Shanks grinned and took the newspaper.

When his gaze fell on "Lynn the Demon Child, a Billion-Dollar Bounty," the smile on his face gradually faded, turning into a hint of surprise.

"Wow... a baby worth a billion Berries?"

He stroked his chin, his eyes becoming playful.

"That Kaido guy, he actually had this trick up his sleeve?"

Lucky Roux, with a chicken leg dangling from his mouth, mumbled, "This brat... sounds scarier than Kaido!"

Ben Beckman, puffing on a cigar, calmly analyzed the situation.

"A baby that the Navy Headquarters takes so seriously and offers a bounty of one billion... is definitely not simple."

"His arrival is likely to disrupt the existing balance of the new world."

Shanks nodded, a thoughtful look flashing in his eyes.

"Yes... this sea is becoming more and more turbulent."

He put down the newspaper, picked up the bottle, and took another swig.

"A mere baby poses such a threat... This era is truly spiraling out of control."

He looked at Ben Beckman.

"It seems we need to speed things up."

"That child's situation has further solidified my resolve."

Shanks's eyes sharpened.

"Ben, how's the letter to Old Man Whitebeard coming along?"

"We must meet with him as soon as possible."

"The appearance of this 'demon child' is just the beginning."

"Next, there will likely be even more astonishing changes on this vast sea."

Ben Beckman nodded, his expression grave.

"Understood, Captain. I will arrange for the Lockstar to be sent over tomorrow."

……

"A billion! A billion Berries, woohoo!!!"

"My son, Kaido's son, even with his first bounty, surpasses the entire world!!"

"Hahahaha..."

Kaido's booming, deafening voice exploded in his ears.

"A bounty of...one billion?!"

Lynn opened his eyes and immediately saw Kaido, who was as huge as a small mountain, waving a bounty poster in his hand.

Above it was his own portrait, along with that dazzling string of numbers... a genuine billion Berries!

"Whoa! He's awake! The little devil's awake!"

When Kaido discovered that Lynn had woken up, his enormous dragon face was almost touching him, his copper bell-like eyes filled with undisguised excitement and pride, and his hot breath was almost blowing onto Lynn's face.

"Young Master Lynn!"

"Young Master is awake!"

Around them, King, Queen, Jack, and the Flying Six, including Who's Who and Black Maria, all gathered around, their faces filled with barely suppressed fervor and awe.

The way they looked at Lynn was no longer simply as an infant in need of protection, but as a true maritime overlord destined to stir up the winds and waves in the future!

"How are you feeling, kid?"

Kaido grinned, his large, fan-like hand cautiously trying to touch Lynn, but his movements were somewhat clumsy, as if he were afraid of accidentally hurting his precious adopted son.

Lynn blinked her big, clear eyes and moved her small body slightly.

He still remembered the time he failed to force his way into the eighth gate, and then everything went black as he lost consciousness.

[Ding! Host awakens; bodily functions have largely recovered.]

[New task added:]

[1. Activate and unleash the Eighth Gate of the Eight Inner Gates Formation: the Gate of Death. Quest Reward: One random ability from the myriad realms.]

2. Intercept Loxda's letter. Mission reward: Massive increase in stamina.

[3. Before the age of three (current age one year and three months), defeat a character with the strength of a Shichibukai or higher in a direct confrontation. Mission Reward: One random ability from the Multiverse.]

In my mind, the cold system notification sounded right on time.

Lynn frowned slightly as she looked at the task details that appeared on the screen.

Intercepting Lockstar's letter?

Wasn't that the letter that the Red-Haired Pirates sent to Whitebeard?

To carry out this mission means that it is very likely that we will have direct or indirect contact with the two Yonko, Whitebeard and Shanks!

This is no joke!

Another example is defeating a Shichibukai-level figure before the age of three...

He is only a little over a year old. Although he can unleash amazing power with the Eight Gates, none of the Seven Warlords of the Sea are seasoned veterans with extensive experience.

but.

The difference in strength between the Seven Warlords of the Sea is enormous.

He could pick on the easy targets.

But then...

Doesn't that mean we've offended the World Government behind the Seven Warlords of the Sea again?

In his last mission, he had already offended the Navy.

He ended up with a 1 billion Berry bounty on his head.

If it weren't for the faction of Kaido of the Beasts protecting him, he probably wouldn't have survived to wake up!

As a result, his next two missions led him to offend two of the Four Emperors and the World Government.

Is the system trying to kill him by making him live too long and sending him to meet the King of Hell sooner?

"Kid, that Sasaki guy was bragging to me about some kind of 'door-opening' technique you used, and how it even produced blood-red steam at the end?"

Kaido's booming voice interrupted Lynn's thoughts. His eyes burned with anticipation as he stared at Lynn. "Demonstrate it again! I want to see for myself what kind of power that is!"

"Oh dear, Mr. Kaido, young master Lynn has only just woken up, and his body is probably not fully recovered yet, is it?"

Quinn chimed in with a sly grin, a fawning smile plastered on his fat face, but his eyes were also filled with barely suppressed curiosity and longing.

"That's right, Governor Kaido. That level of power outburst must have taken a toll on Young Master Lynn. It would be best to let him rest more."

Jin also spoke up, his tone tinged with concern, but his fiery eyes were also fixed on Lynn, clearly eager to see him too.

They had all heard the almost mythical descriptions from Sasaki: the Conqueror's Haki clearing the field, the punching of a lieutenant general, and the blood-red steam.

But hearsay is never as impactful as witnessing it firsthand.

Especially the "eighth gate" that Sasaki mentioned, which is said to be capable of destroying the world, is so exciting and captivating that just hearing about it makes one's blood boil and one yearns for it.

Lynn glanced at Kaido, who was full of anticipation and couldn't wait to have him perform, and then swept his gaze over the eager eyes of the Beast Pirates' officers around him.

He actually wanted to try again.

Although the previous attempt to forcefully break through the eighth gate failed, resulting in severe physical exhaustion, the third old task prompted by the system, "Limit Breakthrough"—opening and casting the eighth gate of the Eight Gates Formation, the Gate of Death—is rewarded with a new opportunity to draw abilities from the myriad worlds.

He was really tempted by this reward.

If he can acquire a new ability this time, whatever it may be, it will be a huge boost to his strength!

Thinking of this, Lynn nodded solemnly.

He sat up straight on the cushion that Kaido had specially prepared for him, which was made of the softest giant beast fur.

"Eeya ya! (I'll give it a try!)"

"Oh?"

Upon seeing this, Kaido's eyes lit up instantly, and he excitedly rubbed his large, fan-like hands together, making a series of cracking sounds from his knuckles.

"Is it coming? My men, open your eyes wide and look carefully! This is my son, Kaido's son!"

The Beasts Pirates' officers, including the Three Disasters, held their breath, their eyes fixed intently on the small figure in the center of the field, afraid of missing a single detail.
