Luffy's ability to Future Sight is something that will only happen in the future. Does the man in black already know that? If that's the reason, there's absolutely no need for him to explain it to Vic. Unless the man in black knows that Vic also knows about that future, that would be too terrifying and the least likely explanation!
Of course, there are other reasons as well, such as accumulating strength to leave more manpower for the final all-out attack on the World Government and the Celestial Dragons. A master like Katakuri is also rare.
For example, Nika is just a code, used to distinguish whether someone is on the same side. Although this world is heavily sealed off, there are still some people who know the legend of the Sun God Nika. In the final battle, they would all be comrades on the same side. There are too many possibilities, so Vic couldn't figure out what the man in the black robe meant.
Vic pondered for a long time but couldn't figure it out, but the scene he saw on the Red Line must have actually happened. The seven equally powerful experts were now standing before him, stronger than anyone he had ever seen!
Is that the ceiling of combat power in this world? How does it compare to Imu? How many people possess such power? Wouldn't the so-called Emperor of the Sea be a joke? There are even stronger forces lurking behind the scenes!
Vic solved one mystery, but others followed one after another. The changes in this world were beyond Vic's comprehension, becoming increasingly complex. Although Joy Boy was dead, it seemed he had left many backup plans!
Unable to understand, Vic stopped thinking about it. He felt that his current strength was still insufficient, which was why he couldn't access the world where the man in the black robes lived.
Once he reaches a certain level of strength, he will be able to uncover more secrets of this world, such as the Three Ancient Weapons, the Celestial Dragons ' National Treasure, the Void Century of history, and how the geography of this world was formed!
Vic had thought that the Emperor of the Sea's combat power was the ceiling of this world, but now he finally understood the height of the world and had a new goal to surpass: the black-robed man who had just appeared!
Vic vanished like Inazuma, reappearing on the deck of a warship. The branch Vice Admiral had regained consciousness and was leaning against the outer wall of the cabin, looking somewhat listless.
Although Vic received emergency treatment, it wasn't enough time, and his injuries are still quite severe. However, he should be able to recover with time and rest.
Several other marines who had been knocked unconscious by Katakuri 'Conqueror's Haki have also regained consciousness and are helping the ship's doctor treat their comrades.
These are the few marines who are relatively unharmed, but if Vic hadn't come, they probably would have been finished off. Of course, there are also a few unlucky ones who are already dead and can no longer stand up!
" Vice Admiral Dark Dragon! These soldiers have likely been affected by the power of Devil Fruit. They're not dead yet; they're still breathing faintly. Do you know how to treat them?"
Just as Vic was observing his surroundings, a man dressed as a ship's doctor in a white coat saw Vic's arrival and his eyes lit up with hope. He took a few steps forward, stood in front of Vic, pointed at the people in naval uniforms, and asked them a few questions.
He was just a ship's doctor, good at treating injuries and illnesses, but he really couldn't treat the damage caused by Devil Fruit. However, he couldn't just watch those people die. The only Devil Fruit User here was Vic, who also had the highest military rank, so he naturally placed his hopes on Vic.
"Try soaking them in fresh water!"
Vic used his Observation Haki to sense that the marines who had been drained dry were indeed still breathing. Looking at their familiar appearance, Vic thought of Luffy who had been drained dry by Crocodile.
Luffy recovered by absorbing water after being drained by Crocodile. Vic deduced that the marines who were juiced were also dehydrated, so he decided to try anything, even though Vic's abilities couldn't save them.
"Alright! You guys quickly move them to the bathroom to soak in water, the rest of you continue to help bandage the wounded!"
After hearing Vic's words, the ship's doctor felt reassured and, after giving a shout, personally carried a mummified marine into the cabin.
Meanwhile, Vic used his electric shock to treat a dying marine. After the marine's heart resumed beating, Vic used his ability to heal his fatal wounds until he was out of danger. This man had already been examined by the ship's doctor, who found no way to help him and had reluctantly given up on him.
Vic's suggestion worked; the marines who had been drained dry began to frantically absorb water after encountering fresh water.
Although their bodies returned to normal afterward, they did not regain consciousness. Smoothie's Devil Fruit ability was ultimately different from the Sand-Sand Fruit; the juice it extracted was not entirely water!
Fortunately, they are out of danger, but it will take a long time to recover. All those who could be saved on the warship have been saved; the rest cannot be saved!
This is already a very good result. Other warships would basically be wiped out if they encountered Katakuri. Pirates don't capture people or leave them alive unless they have a special purpose!
" Mora is dead. Katakuri was lucky he escaped. You don't need to go to Impel Down anymore. Find Marine Base to rest and recuperate before returning to headquarters. I'll report to headquarters. There's no need to rush!"
Vic didn't offer much comfort to the branch Vice Admiral. As a marine who deals with pirates every day, he was bound to encounter something like this sooner or later.
Although this matter was caused by Vic, both of them were working for the Navy, so it's hard to say who was right or wrong. This was not the outcome they wanted either. Now, Vic couldn't personally escort them back to headquarters, as he also had his own mission to complete.
After greeting them, Vic vanished like lightning from the warship's deck. The series of events had left Vic's heart still reeling.
He would definitely report the events to headquarters, but he didn't intend to report the appearance of the man in black robes.
The man in black robes had the absolute power to kill him, Vic could clearly sense that, but the man in black robes did not do so, mainly to stop Vic from killing!
Overall, both Vic and Katakuri benefited. Katakuri mastered Observation Haki, which allows him to Future Sight, while Vic learned a shortcut to make his body stronger again.
Vic didn't sense any malice from the man in the black robes. If this were reported to Marine Headquarters, what difference would it make from notifying the World Government's Five Elders Imu?
Furthermore, given the black-robed man's strength, if he were to remove his robes and simply hide away somewhere, who could find him? And even if they did find him, so what? Without Imu's personal intervention, who could stop him?
Therefore, the report is not very meaningful, and it might even lead to Imu's premature birth, causing a huge change in the world order, which is not what Vic wants.
