----------

Although Vivi's opponents were Alabasta's two guardian warriors, Chaka and Pell, neither Cobra nor the warriors themselves were worried about Vivi's safety. From Nico Robin's account, they already knew Vivi's general strength level. The fact that she could fight against Crocodile was enough to show how powerful she had become.

If Robin hadn't mentioned that Ikki collected famous swords either personally or by having his crewmates defeat the sword owners, Chaka and Pell would have simply given their swords directly. After all, this could be seen as their blessing for Ikki and Vivi's wedding.

"Princess Vivi, be careful," Chaka said, standing with his sword in both hands, his expression growing serious.

"Chaka, Pell, give it your all," Vivi replied. "Don't go easy on me just because I'm a princess."

The corners of Vivi's mouth lifted slightly as she drew her Zanpakutō, Sode no Shirayuki, in a semicircle before her. Under the influence of Water Breathing, the blade left a trail of water in the air. At the same time, an intense sword aura radiated from Vivi and pressed down on Chaka and Pell.

The two warriors were shocked, both looking at the seemingly fragile Vivi with surprise. Although they knew she was powerful, when they actually felt her strong aura, they were quite stunned.

"If that's the case, I'll use my full power," Chaka said, seeing more water gathering around Vivi's sword. He took a deep breath and used his Devil Fruit ability to transform into his jackal form.

Beside him, Pell also activated his Devil Fruit ability and rushed toward Vivi. Their swords attacked from different angles.

Faced with the dual assault, Vivi's eyes narrowed, becoming extremely calm. "Water Breathing, Eleventh Form: Dead Calm!"

With a soft utterance, a large amount of water suddenly appeared around Vivi, wrapping around her in waves. But in an instant, all the water became perfectly still. Vivi appeared to be standing on an incredibly calm lake.

"Water?" Chaka glanced curiously at the real water beneath his feet but continued his attack alongside Pell.

What he didn't notice was that the movements caused by their attacks were being transmitted to Vivi through the water beneath their feet. Vivi seemed to anticipate Chaka and Pell's strikes in advance. She closed her eyes, took a few casual steps, and effortlessly avoided all their attacks.

This sight made Koza, Cobra, and the other onlookers widen their eyes in astonishment. From their outside perspective, Cobra could tell that Vivi was toying with Chaka and Pell. Koza was even more impressed—watching Vivi fight Chaka reminded him of how Chaka used to easily outmaneuver him with swordsmanship.

"Captain Ikki, is this the Water Breathing swordsmanship you taught Vivi?" Cobra asked excitedly, grabbing Ikki's hand. Seeing his daughter's power with his own eyes, he was naturally thrilled.

"The Eleventh Form of Water Breathing is considered a secret technique," Ikki explained with a smile. "When using this sword form, the user enters a state of tranquil water. When an enemy attack comes close, the user can easily dodge or even neutralize it. The water beneath Vivi's feet makes this effect even stronger."

Even Ikki himself was quite satisfied with the Eleventh Form of Water Breathing. Attacks from warriors of Chaka and Pell's caliber were no challenge. Ikki believed that Vivi could even deal with some powerful Paramecia Devil Fruit attacks using this technique. In fact, he thought that if Vivi were a bit stronger, she could have used just this move to defeat Crocodile.

As Ikki finished speaking, Vivi suddenly opened her eyes. She walked casually past Pell and Chaka, swinging her sword twice with lightning speed. Then she sheathed Sode no Shirayuki, and the surrounding water instantly vanished.

[Ding! Host's crew member Vivi has defeated Chaka and can now claim his famous sword 'Jackal'!]

[Ding! Host's crew member Vivi has defeated Pell, and you can now claim the famous sword 'Falcon'!]

"It's over," Ikki thought, his lips curving into a smile as he heard the system notifications in his mind.

Rip!

The sound of cloth tearing could be heard as Chaka and Pell looked down to find that the collars around their necks had split open.

"That's... amazing," Chaka said. "Princess Vivi's power is now way beyond us."

Chaka sheathed his sword and handed both weapon and scabbard to Vivi. Pell did the same.

"Thanks, Chaka and Pell," Vivi said with an apologetic smile as she accepted their swords. "But I've convinced Captain Ikki to teach you both swordsmanship later. Maybe you can also learn the same Water Breathing technique as me."

Hearing this, Pell and Chaka's eyes lit up, and they both looked at Ikki with excitement. Naturally, Ikki nodded in agreement with Vivi's statement.

"Haha, looks like Alabasta will have two more powerful swordsmen in the future," Cobra laughed. "Today is truly a happy day. Come, Vivi, Chaka, and Pell. Everyone, gather round! The banquet should officially begin now. After we eat, we still have wedding preparations to take care of."

"Seriously, Father, how eager are you for this wedding?" Vivi blushed as she walked over to sit beside Ikki, handing him the two swords from Chaka and Pell.

"Thanks, Vivi," Ikki smiled and immediately chose to upload the two swords to his system.

[Ding! Host uploaded the grade sword 'Jackal'. Congratulations on receiving one lottery chance.]

[Ding! Host uploaded the grade sword 'Falcon'. Congratulations on receiving one lottery chance. You now have 2 lottery chances in total.]

Ikki didn't hesitate and mentally issued a command to the system.

[Starting lottery... Congratulations to Host for winning: 'Mountain-Cutting Swordsman Challenge Permission' x1, 'A-Level Nutritional Potion' x5]

[Note: 'A-Level Nutritional Potion' lasts for 2 hours and can only be used once per day.]

'Hmm? I only got five bottles of A-level nutritional potions this time. Plus, the exercise duration has been extended, and the daily usage limit has been reduced,' Ikki thought. 'Is it because A-level nutritional medicine is more powerful? I hope this stuff can increase my life force to the next level.'

Ikki quickly shifted his focus to the other prize he had won.

'A permission to challenge a swordsman in the Mountain-Cutting Realm. If I succeed in the challenge... My swordsmanship has also reached the Mountain-Cutting level. This might allow Zangetsu to transform into Tensa Zangetsu.'

The corners of Ikki's mouth turned up involuntarily at the thought. With a mental command, information about his potential challenge target appeared in his mind.

[Name: Yoriichi Tsugikuni]

[Life Force: 20000, Level A]

[Weapon: Nichirin Sword]

[Sword Realm: Mountain-Cutting Realm]

[Swordsmanship School: Breath of the Sun]

[Special Abilities: Demon Slayer Mark, Transparent World]

'Yoriichi Tsugikuni, so it's him!' Ikki thought. 'Twenty thousand life force points and Mountain-Cutting swordsmanship level. When comparing to Demon Slayer's Yoriichi, I wonder if this is an enhanced version. He has the Demon Slayer Mark and Transparent World abilities too. This challenge target seems a bit troublesome. It would be safer to train first before challenging him.'

Ikki hadn't mastered the 'Demon Slayer Mark' or 'Transparent World,' and his swordsmanship realm hadn't officially reached the 'Mountain-Cutting Realm.' He had no way to guess how strong Yoriichi would be with these powers.

Even though Ikki had abilities that Yoriichi didn't, and wielded the better weapon Zangetsu, he decided to wait until his life force increased before taking on the challenge. He didn't want to waste the "Mountain-Cutting Swordsman Challenge Permission" he had just won.

'If I beat him, I wonder if I can get the 'Demon Slayer Mark' and 'Transparent World' abilities,' Ikki mused. 'The Transparent World would be pretty useful. But if I defeat him and get the Demon Slayer Mark, will it force me to activate it?'

Ikki frowned slightly. He knew that people with the Demon Slayer Mark could imitate other breathing style users, but those who developed the mark would not live past 25. Those who developed it after 25 would die even sooner.

Ikki didn't want himself or his crew members to activate the Demon Slayer Mark just for power. Otherwise, with his strength and knowledge of how to awaken it, he could have done so already.

"Ikki? What's wrong?" Vivi's voice reached his ears, bringing him back to the present.

"It's nothing, just thinking about something," Ikki replied, shaking his head and setting aside thoughts of challenging Yoriichi. He looked up at everyone gathered around the dinner table. "Don't mind me. Let's eat."

Cobra nodded, raising his glass with a smile. "Then, let's toast! To the rebirth of Alabasta, and to Vivi and Ikki's wedding!"

Meanwhile, at the coast of Alabasta, while the banquet was taking place at the palace, a figure that Ikki would recognize all too well jumped aboard the Explorer.

"Who's there?!" Igaram, who was guarding the ship, immediately looked over when he heard the noise.

"It's you, Nico Robin?!"

"Yeah, it's me," Robin nodded slightly, smiling. "Igaram, everything's finished. Crocodile is dead. You can go back now. Leave the job of guarding the ship to me."

Hearing this, Igaram was initially happy—after all, Crocodile's death meant Alabasta was saved. But soon, he frowned.

"Let you guard the ship? You don't seem to be Captain Ikki's crew member."
