He actually wouldn't try to do anything to another Celestial Dragon!
Just one Doflamingo caused the Gorōsei (Five Elder Stars) and the Celestial Dragons to be extremely vigilant. If it were the eldest son of the esteemed Nibelung Family, with even higher prestige, Rowen would face a collective siege from Marine Headquarters' three Admirals, Zero, and the unknown high-end forces of the World Government. There aren't going to be two ways about it!
Considering that he had just sent Fujitora to deal with the trouble named Edward Weevil and their preparations hadn't yet been fully implemented, he was now facing a duel invitation from Lirisk…
Rowen couldn't help but sigh, "What kind of mess is this!"
This matter was probably known by the Gorōsei (Five Elder Stars) and Sengoku. They had remained silent because they were waiting for Rowen's stance.
The youngest Vice Admiral of the Headquarters, a Marine Super Rookie who was comparable to the Three Admirals of the past!
Should they bestow him with heavy responsibilities or bury him, all would be revealed after this duel.
Caught between his identity and various powerful figures' political maneuvers, Rowen was like a small boat sailing out to sea during a rainstorm, facing ferocious waves and constantly on the brink of capsizing!
But he had no choice but to face it head-on!
Because this was the path he had chosen for himself!
"However, no matter what, in this world, Strength and Power reign supreme! Ultimately, that's what matters most!"
Reaffirming his conviction, Rowen walked to the window, gazing out into the distance.
"A month, huh?"
"I hope you won't disappoint me, Lirisk!"
"Hey! Look, so many fish are floating up!"
At this moment, cries of surprise echoed from the square in front of the fortress, causing tremors all around. In the decorative lake built around the outskirts of the square based on the terrain, countless unknown ocean fish floated belly-up.
Huā Lā La!
Suddenly, a sea beast the size of a small truck burst out from the water's surface. It thrashed a few times, gasping for air, then rolled its eyes and fell silent.
Looking at the lake where purple gas soared into the sky and rushed eastward, Rowen's mouth twitched.
"Darn it!"
…
Rowen's power development had reached a bottleneck for some time now, but his bottleneck was different from that of ordinary people. When regular individuals hit a bottleneck, no matter how hard they practiced, they could only maintain their current state, extending their peak period.
This was the case when Zephyr became an Admiral; his strength had stagnated, and he could only maintain his level through consistent training.
However, Rowen was different from ordinary people!
Even if he couldn't figure out the key to developing his Devil Fruit further, particularly the Fusion Violent Ape of Hell Form and Thunder God Seal, his physicality continued to grow stronger relentlessly.
For a long time, apart from the time before he jumped into the sea to escape the explosion in Dressrosa, Rowen hardly ever let go of the Thunder-Lightning Stimulation Method!
In fact, the Thunder-Lightning Stimulation Method he used now had already evolved beyond the state where he had to die or be incapacitated after each practice. It was latent within him, forming a new instinct.
The all-encompassing cell stimulation coupled with the abundant nutrients of the One Piece World's food was akin to being in an idle game, constantly strengthening his physique. As his physique strengthened, it also bolstered the power of his Devil Fruit ability.
In this state, it could be said that Rowen was always growing stronger, although the recent rate of improvement was limited.
Previously, Lirisk didn't pose much of a threat to Rowen, and he only had a slight possibility of defeating him. But now, hearing that Lirisk's strength had significantly increased after recovering his senses, Rowen was looking forward to clashing with him.
…
Time flew by, and a month of seclusion passed unnoticed. In the Underground training room of the G-10 Marine Branch, Rowen supported his body with his thumb, his feet upside down, moving up and down in a continuous rhythm as he exercised.
"One thousand eight hundred ninety-seven… One thousand eight hundred ninety-nine… Huff! Huff!"
Surprisingly, even someone as powerful as Rowen became so disheveled after doing less than two thousand single-finger push-ups.
His body was drenched in sweat and he was panting like a bull as sweat dripped from his sharply defined muscles like raindrops, pooling on the floor beneath him.
But if anyone looked at what he was propping up with his feet, they would understand immediately.
Seastone!
It was a Seastone disc about the size of a plate!
Aside from mud, the G-10 Marine Branch was most abundant in Seastone! They have a lot of it.
In the face of Seastone's restraining effect on Devil Fruit Ability users, Rowen not only had to use his feet to maintain balance and prevent it from falling off but he also had to support his body to perform single-finger push-ups without tiring.
After arriving in this world, Rowen unraveled a mystery.
Besides rendering Devil Fruit Ability users powerless, how strong was the effect of Seastone's restraint on their strength? For instance, Luffy fell flat on the ground the moment he touched Seastone.
But it was different for Ace, before his execution, Ace had the strength to scream and shout hysterically.
Faced with such contrasting cases, the true efficacy of Seastone was worth probing.
After several attempts and careful comparisons, Rowen finally found the answer.
There was no specific numerical value of the suppression effect of the Seastone!
Upon contact with Seastone, a Devil Fruit Ability user would instantly plummet from the clouds into the abyss, becoming as weak as an ordinary person.
It wasn't a value that varied from person to person; it was a fixed effect!
No matter how powerful a Devil Fruit Ability User was or how much of their body was in contact with Seastone, its effect as the crystallization of the sea remained the same in restraining any Devil Fruit Ability user!
Even if someone as formidable as Whitebeard was clamped with Seastone handcuffs, he wouldn't be any stronger than an ordinary person.
It was a fixed effect that directly erased the part of a Devil Fruit Ability user's strength that exceeded that of an ordinary person. No matter how much that was or how terrifying it was, they wouldn't be able to unleash a punch stronger than that of someone with 10 Doriki Value.
Converted to Doriki, Luffy's physical quality would certainly far exceed that of an average person. The strength that vanished the moment he touched Seastone was many times stronger than the strength retained in his body!
