"Haki is about manifesting your own spirit as a weapon for attack."
Sitting on a wooden stool by the worksite, Fujitora, leaning on his cane, explained seriously to Vivian.
"Manifesting spirit?"
"Exactly."
Fujitora raised his right hand, and a black layer, like ink, covered his skin.
"This is the basic use of Armament Haki. The next level is..."
Boom!
Before he finished speaking, Fujitora slammed his fist into the ground, sending out a shockwave that created a small crater.
Vivian was stunned, thinking it looked like a martial arts movie with techniques like the Six Meridians Divine Sword.
"This is a higher level of Armament Haki, called Emission. It can create shockwaves or form a protective barrier to block attacks."
Fujitora explained.
Armament Haki has three stages: the first is hardening the body, similar to the Navy's Iron Body technique, enhancing attack and defense, and allowing attacks to hit Logia Devil Fruit users.
The second stage is coating, where Haki can be wrapped around weapons or projectiles.
The final stage, as Fujitora demonstrated, is emission.
Currently, those who have mastered emission are among the top fighters in the New World.
"As for Observation Haki..."
Fujitora gestured to Vivian, "Attack me with your fastest speed."
"Alright." Without hesitation, Vivian nodded.
He knew his attack wouldn't hit Fujitora, who had top-tier Observation Haki. Otherwise, he'd be guilty of attacking an elder.
Vivian exhaled sharply, activating Thunder Breathing, and aimed a punch at Fujitora's face.
The surrounding guards, including Domino and Hannyabal, were shocked, thinking Vivian's punch could break a wall.
But...
Just as the punch was about to hit, Fujitora effortlessly dodged it.
Vivian didn't stop, launching a flurry of punches at Fujitora's body.
His arms moved so fast they left afterimages.
Yet, even sitting on a stool, Fujitora dodged every punch perfectly.
Everyone was amazed.
As expected...
No wonder he could defeat a Warlord of the Sea...
Hannyabal recalled how Fujitora had easily defeated several high-bounty pirates trying to escape Level 6.
Each of those pirates had bounties in the hundreds of millions.
Handling one would be tough for him, but Fujitora subdued several at once.
Such strength... isn't it Admiral-level?
Why is he working under Vivian?
Hannyabal couldn't understand.
Neither could the others, except Vivian, understand why this blind man, who only seemed to gamble, was so powerful.
Whoosh!
Whoosh—whoosh—whoosh!
The sound of punches continued.
After a while, a tired Vivian sat down, "I'm done!"
He was a bit angry just now, not at Fujitora, but at himself.
Damn it, I was so close, but why do I always miss?
That feeling of helplessness when your actions are completely seen through by the opponent was something he had experienced before. Every time he was suppressed like this, it fueled his strong desire to become stronger.
"That's enough for the demonstration. Now you need to understand it on your own," Fujitora said, adjusting his posture.
...
The following period was quite routine.
Vivian's daily schedule was roughly as follows:
Wake up and wash up, check the construction progress at the site, lead the prisoners, including Zoro and Jinbe, for a few laps around the playground, then cook.
In the afternoon, he supervised Zoro breaking stones while practicing Armament Haki and Observation Haki nearby.
In the evening, he cooked again.
Then it was time for board games and entertainment.
The whole day was fulfilling and pleasant, except that his activities were limited to Level 6 underground. This prevented Vivian from swimming in the sea and hunting Sea Kings for cooking, which he had originally planned.
This routine continued for about two months. Under Vivian's guidance and supervision, the Infinite School on Level 6 was finally completed.
Yes, Vivian changed the name from "Infinite Hell" to "Infinite School" and had a plaque made, which he hung on the wall at the entrance.
In addition…
There was a playground, a teaching building, an arts building, toilets, and dormitory cells.
There was still about 1,000 square meters of space left, mostly empty except for Vivian's two-story villa. He hadn't decided what to build there yet, maybe some plants or a swimming pool?
In short, the once empty and lifeless Level 6 prison had been completely transformed by Vivian's master-level craftsmanship.
"It's really well built." Vivian stood with his hands on his hips, looking quite pleased.
But he worried that after two years, he might get too comfortable here and not want to return to the headquarters.
"Chief Warden Vivian!"
Several guards stood at a distance, waving at Vivian, "Do we need to take the prisoners to the construction site today?"
"No, bring the prisoners from Levels 1 and 2 to the second floor of the teaching building for class."
"Class?" The guards looked at each other.
"Chief Warden Vivian, what kind of class are you going to teach the prisoners?"
"No idea..."
"What's the point of teaching prisoners? It's strange."
"Who cares, let's just bring them. As long as Chief Warden Vivian is happy, since he's in charge of the prison's food now."
With that, they turned and quickly ran up the stairs.
