Kamui!

After One Piece Roger was captured, the world erupted into turmoil. Many Pirates who worshipped Roger began causing trouble across the world, attacking quite a few Marine branches and inflicting considerable losses on the Marines.

At Marine Headquarters, Marineford, most of the Marines' top combat forces had returned after Roger's capture, guarding against Roger's Crewmates coming to break him out of prison.

Only Garp knew that the other members of the Roger Pirates would not come to rescue him, but no one else did. As a result, everyone was on edge, treating every rustle of grass and every tree as a potential enemy.

Carlos did not pay attention to the upheaval in the world for the time being. Instead, he focused all his efforts on intensive training. After five months of grueling cultivation, his overall strength had improved tremendously. He was about to reach his training target—and perhaps even surpass it!

At noon two days later, Carlos returned from his training grounds to the cabin. His upper body was bare, revealing well-proportioned, perfectly sculpted muscles. He wore loose black trousers below. Yet the most eye-catching thing was his eyes: black triangular sickles had emerged within his crimson pupils, eerie, cold, and powerful!

After returning to the cabin, changing into clothes, and gathering a few things, Carlos stepped outside and took one final look at it. A spatial vortex appeared and swallowed him into its depths, making him disappear completely.

Lucifer Manor was the Mike Family estate's new name. After returning to the manor, Carlos immediately summoned his subordinates' leaders and gave his orders. Noah would temporarily handle the family's affairs in his place, while Carlos left with Kelly.

As Carlos's confidant, Noah held one of the senior leader positions. The other two senior leader positions were occupied by the two strongest leaders: one was named Nicky Shorey, and the other Brian Hawke.

At a Mafia-controlled dock in Iron Island East City, a small ship had long since been prepared. It was roughly the same size as the Going Merry, Luffy's first pirate ship, though it was somewhat longer and narrower.

The ship had already been stocked with enough drinking water and food. Essential sailing personnel, including a navigator, shipwright, and doctor, had also been assigned. It could set sail at any moment.

Carlos boarded the ship with Kelly and five carefully selected Mafia combatants. All the Crewmates respectfully welcomed them. The people aboard were not Carlos's companions, but his subordinates.

After boarding, Carlos briefly encouraged his subordinates. He kept the navigator behind and dismissed everyone else.

The navigator his subordinates had found was reasonably capable. He might struggle somewhat in the Grand Line, but sailing through the Four Blues would be more than manageable for him.

The seas of the Four Blues were dangerous as well, but compared to the Grand Line and the New World, they were far less perilous.

"I'm going to East Blue. Find me a route that gets as close to Mary Geoise as possible. Obstacles don't matter. Just stop beneath the Red Line in the end."

"Do you understand what I mean?"

"Boss, you mean we won't enter East Blue through Reverse Mountain. You have another way to cross the Red Line and enter East Blue, right?" the navigator beside him asked cautiously.

"That's right. That's exactly what I mean."

"I understand. I'll plan the route immediately. We won't go through Reverse Mountain. If nothing unexpected happens, we'll arrive soon."

"Go."

"Yes."

Ten minutes later, the ship left the dock and sped toward the Red Line where Mary Geoise was located along the shortest planned route.

The seas of One Piece were divided by the Red Line and the Calm Belts flanking the Grand Line. The most common way to cross the seas was naturally to enter through the currents branching off from Reverse Mountain.

Besides that, a more convenient method was to cross the Grand Line encircled by the Calm Belt or cross the Red Line. That would allow one to travel freely through the Four Blues and even the Grand Line.

Of course, saying it was easy, but very few could truly accomplish such a thing. Crossing the Grand Line surrounded by the Calm Belt was somewhat easier. Marine warships fitted with Sea Prism Stone on their hulls, as well as certain top-tier powerhouses, could make the crossing.

The hardest part was crossing the Red Line. Strength alone was not enough; one needed special abilities, such as climbing or flight.

Taking the West Sea where Carlos was as an example, if he wanted to go to East Blue or South Blue, the most convenient method was to cross the Red Line. To reach South Blue, he could cross directly in a straight line, choosing any section of the Red Line.

Going to East Blue was more troublesome and required a diagonal crossing. He could cross from Reverse Mountain or from Holy Land Mary Geoise. In fact, since Carlos was in the Southern West Sea, crossing from Reverse Mountain would be closer.

The reason he chose the longer route and crossed from the Red Line where Mary Geoise was located was because Carlos wanted to visit Marineford and witness Golden Lion wreak havoc at Marine Headquarters. He wanted to see the splendor of one of this world's strongest men!

If Carlos wanted to go to North Blue, then he would not cross the Red Line. Instead, he would cross the Grand Line surrounded by the Calm Belt—and specifically the Grand Line where the New World was located, not the first half of the Grand Line.

They sailed at full speed. Strangely enough, they did not encounter a single Pirate ship along the way. They did come across quite a few merchant ships and passenger ships, though. Their luck was unbelievably good.

Perhaps that was normal. After all, the West Sea was vast, and the Great Age of Pirates—the Great Pirate Era—had not yet begun. Whether in the Four Blues, the Grand Line, or the New World, the density of Pirates was still low. It was not strange that they had not encountered any.

Once the Great Age of Pirates began, sailing the seas would mean such a dense Pirate presence that not encountering Pirates would be the strange thing. Pirates would be everywhere, impossible to kill off completely. Even by the time Luffy set sail, the Marines were still plagued by headaches over them.

After a day and a half, they finally arrived beneath the Red Line. Carlos and the others stood on the deck, marveling at the towering reddish-brown continent that stretched into the clouds. Carlos clicked his tongue in wonder as well. Sailing really was interesting; one got to see so many fascinating things...

"After I leave, go rest on the nearest island for now. Keep a low profile. When I return, I'll notify you through a Den Den Mushi to come pick me up."

"Understood?"

"Yes!" everyone quickly answered respectfully, though their eyes were filled with curiosity as they stared at Carlos, wanting to know how he would cross the Red Line towering into the clouds...

Carlos turned to face the Red Line. His eyes transformed into the triangular-sickle Mangekyō Sharingan. This was Obito Uchiha's Mangekyō Sharingan, and the complete version at that—the most overpowered Mangekyō Sharingan imaginable!

Kamui!

Visible spatial vortices suddenly appeared in midair. Carlos's body twisted with the vortices, becoming boneless like a paper figure as it was sucked inside. It was eerie yet cool, and he vanished in an instant!

The Eye of the Devil imitated the Mangekyō Sharingan's abilities, but it did not imitate the Mangekyō Sharingan's side effects. Going blind was impossible. It would never happen in this lifetime...

The Eye of the Devil was a Special Paramecia. How could the Devil's eyes possibly go blind?

Everyone stared dumbfounded at the sight of Carlos vanishing. They had imagined dozens of ways their Boss might cross the Red Line, but they had never imagined this method...

After a long while.

"Spatial ability?" Kelly murmured, her gaze somewhat unfocused.

"Seems like it."

"That's incredibly powerful. With an ability like that, couldn't he travel anywhere in the world at will?"

"Boss is amazing. I'm following Boss for the rest of my life."

"That lacks sincerity. This little brother is willing to eat, drink, visit brothels... no, risk life and limb for Boss!"
