Aside from his initial genuine anger, Vic's subsequent anger and helplessness were feigned; he had to do it to clear himself of suspicion!
Seeing those hopeful eyes, he had already devised a plan to wipe them all out. He had already quietly set up an electric field at the scene, waiting for them to walk away so he could remotely control the electrical signals to kill them, thus providing an alibi.
If someone were to perform an autopsy and see all these various causes of death, all stemming from internal causes, I wonder what they would think. But they certainly wouldn't suspect him, given that he possesses the Logia Rumble-Rumble Fruit, because the Rumble-Rumble Fruit's power can't accomplish these things.
Vic quickly composed himself, putting on an indignant and aggrieved expression, pretending he hadn't done anything, and reluctantly headed towards the warship. Rebecca and the others also gradually suppressed their smiles along the way; their acting skills were lacking, so they could only keep a cold face.
" Vic! Gion! What's wrong? Why do you look so pale? What happened?"
Tokikake waiting on the deck, Jiaji noticed that Vic and the others looked unwell and hurriedly asked what was wrong. He had too much confidence in Vic and hadn't even used his Observation Haki to investigate, otherwise he might have been furious too.
Ignoring Jiaji's Tokikake, Vic angrily reached out and unleashed a bolt of lightning from his palm, shooting straight towards the distant sea. There, a Sea Kings Sea Kings been following the warship was struck by Vic's lightning and rolled its belly up, instantly dying.
" Tokikake! Go and fish it out for me, I want to eat meat."
Vic stared at Jiaji Tokikake a harsh tone, as if to say, "If you don't Tokikake the next move, Jiaji, it'll be your next attack."
"I'll go! I'll go, okay? Wait for me!"
Seeing this, Victor didn't dare to provoke him. Without even taking off his clothes and shoes, he plunged into the sea and quickly swam to the Sea King, dragging the Sea King's tail as he swam towards the shore.
Tokikake was still pondering what had happened on the island to make Vic lose his temper like this. He felt that Vic was just using this as an excuse, saying he wanted to eat meat was just a way to vent his anger.
So the Sea Kings were happily splashing around in the sea suffered a terrible fate and paid the price with their lives. Tokikake, they concluded that they should never go wild when others are angry, or they will die or be completely destroyed!
"Let's go, it's all burnt from the electricity, I don't want to eat it anymore!"
After dragging the Sea Kings ashore, Vic and the Tokikake glanced at it and said something, then jumped onto the warship without looking back. Rebecca and the others followed suit, jumping onto the warship without a word. Tokikake looked at it and found that some parts were indeed burnt, but most of it was fine. There was so much meat that they could eat as much as they wanted!
" Vic! Only a small part is burnt, the rest is still edible, don't waste it..."
"Um?"
Tokikake, unaware of Vic's thought process, felt it was a real waste to do so, and thus tried to persuade Vic as he walked away.
But before he could finish speaking, he was intimidated by Vic's undeniable nasal tone and dared not continue. So he jumped onto the warship and ordered it to set sail. The supplies were already prepared. If Rebecca and the others hadn't been still on the island and the warship hadn't already departed, they might have missed this incident.
As soon as the island disappeared from the warship's sight, a voice echoed in the minds of the civilians who had just suffered the disaster, "Everyone, go to the beach and take a look!"
Although it is the same sentence, the tone and timbre of the voice are different for each person, including men, women, young and old.
Those who heard the voice were confused, looking around for its source, but the voice seemed to resonate directly in their minds, making it impossible to pinpoint the person's location.
So people who knew each other started asking each other if they had heard anything, and then each person described what they heard. There were voices of men, women, the elderly, and children. They even started arguing because what others heard was different from their own.
Until someone shouted, "It's a god!" and then many people started shouting it too, believing it. If it weren't a god, who else could simultaneously make the voices of men, women, young, and old resonate in everyone's minds?
After their cheers subsided, they returned to the literal meaning and began walking towards the sea. Upon reaching the shore, they saw the Sea Kings of flesh that Vic had left behind, and they were overjoyed!
This was a gift from the gods, who saw that their houses had been burned down and their food was wasted, to help them rebuild their homes. They knelt beside the Sea Kings and cried out to the gods again. On the distant ocean, out of their sight, a young man smiled.
Meanwhile, Rebecca on the warship had already told Tokikake what had happened on the island, but she didn't tell him that Vic had killed all the perpetrators at once. She acted as if she knew nothing about it. Anyway, when Vic unleashed his ultimate attack, neither of them could see each other, and they were facing away from each other, so this strange event had nothing to do with them.
However, Kaji got a little carried away Tokikake Rebecca's story. He couldn't stand such things, but he was also somewhat helpless when he heard the other party's identity. As someone who grew up listening to stories about the Celestial Dragons, he still had some deep-seated fear of Celestial Dragons!
It's impossible for someone like Vic to have no respect at all and kill someone whenever he has the chance. Vic even suspects that the reason why Grandpa Garp left Luffy and Ace in Foosha Village to be raised by bandits was to avoid being intimidated by the name of the Celestial Dragons!
Luffy really did seem to have never heard of the Celestial Dragons. He almost killed one of them with a single punch in Sabaody Archipelago without any fear, and he didn't have any concept of how terrifying the Celestial Dragons were.
Another one is Zoro, who almost killed Celestial Dragons. It seems like everyone from the East Blue is ignorant and unsophisticated. However, Nami was terrified of the Celestial Dragons as soon as she met them. Perhaps Luffy and Zoro are in seclusion, training and don't care about what's happening outside, focusing only on becoming stronger.
The events that had occurred on the island reminded Vic of a momentous event: if he remembered correctly, this year, Fisher Tiger would climb the Red Line with his bare hands, wreak havoc in Mary Geoise, set fires everywhere, and free many slaves.
The Hancock sisters, the Gild Tesoro, Koala, and others all escaped this time and later became very famous figures. Vic speculated that Fisher Tiger to the Red Line might be related to the Celestial Dragons' recent large-scale capture of slaves, but many details are unclear and it is impossible to make a judgment.
After that incident Fisher Tiger left Fish-Man Island and formed the Sun Pirates, bringing many of his rescued comrades into the crew in order to evade the Navy's pursuit.
After sailing at sea for three years, they were found and surrounded by the Strawberry Fleet, led by Vice Admiral Kizaru. In the end Fisher Tiger died, Jinbe escaped, and Arlong was captured.
It was after this mission that Kizaru was promoted to Marine Admiral. It's likely that the World Government put pressure on the Navy, telling them not to promote anyone to Marine Admiral unless they killed the criminals who challenged the Creator of the World.
