# Chapter 837: Uranus Grand Dungeon
Let's set aside the battle happening in Mary Geoise for now, and turn our attention to Ian.
Standing at the bow, watching the seawater waves split apart on both sides, Ian felt that he was probably hopeless when it came to having his own ride. He was always, always hitching rides on other people's ships. This time was even better—he was hitching a ride on the ancient weapon, Pluton...
Measuring approximately 2.3 kilometers in length and about 1 kilometer in width, the "Pluton" Dawn was much smaller than the Golden City Tesoro, but compared to ordinary pirate ships, it was still a behemoth. Ian had never seen the Commodore of the Yonta Maria Grand Fleet who became Luffy's subordinate in the original history, but he imagined that even the ships of the Yonta Maria Grand Fleet couldn't match the size of Pluton.
The restoration work on Pluton had been completed by Vegapunk and Waldo, taking quite a long time. Ian had to admit that although Kaido was crazy, he had finally done something good this time. In his battle with Uranus, although Kaido was killed by Uranus, Uranus was also heavily damaged. After transforming into the Yamata no Orochi, Kaido had torn countless wounds into Uranus's body, causing Uranus to never appear before the world during this period. It was probably hiding away to recover. Ian and the others had taken advantage of this time to complete Pluton's restoration.
Pluton belonged to Buggy—Ian had already made this clear long ago. Because he understood that if he wanted to push Buggy up to become an Emperor, then Buggy at least needed some high-end combat power, and Pluton was the most suitable for Buggy.
It was also quite amusing. Precisely because Ian had no intention of competing with Buggy for Pluton, Buggy was instead full of motivation. He had actually managed to create shells suitable for Pluton's cannons—what Buggy had mentioned before: the Super Super Super Special Buggy Shell!
Without shells, Pluton couldn't be called an ancient weapon. Buggy had stumbled into success through sheer talent...
Now, Pluton was sailing across the sea, with the Straw Hat Pirates' ship and Princess Shirahoshi swimming in the ocean beside them. Ian's purpose naturally needed no explanation.
They were going on the offensive, seeking trouble with Uranus!
After being injured, Uranus had hidden away to recover, but its location had long been discovered by the reconnaissance personnel sent out by the Whitebeard Pirates. After all, given Uranus's enormous size, unless it flew above the clouds, it was very difficult to hide on the ground.
After discovering Uranus's hiding place, the three Emperor crews—the Dragon Hunter Pirates, the Whitebeard Pirates, and the Red Hair Pirates—had made arrangements. Using a large number of personnel, the three crews secretly evacuated the civilians from approximately twelve islands near Uranus's hiding place.
The people from these twelve islands had now all moved to live in Ian's Mugi Country. What remained were only uninhabited islands. The area covered by these uninhabited islands was roughly over two thousand square kilometers.
The reason for doing this was to clear out a battlefield, allowing them to focus entirely on fighting a great battle with Uranus...
"Do you understand your mission, Buggy?" Ian was currently explaining to Buggy what he needed to do when the battle started. "After forcing Uranus out, while I'm holding Uranus back, you and your men must clear these islands as quickly as possible! We can't let Uranus have any place to land!"
"Don't worry! As long as I don't have to fight Uranus head-on!" Buggy laughed, patting his chest.
Hearing this, Ian was a bit speechless. It seemed this guy still had some self-awareness.
The main combatant this time was naturally Ian. After all, to fight against the flying Uranus, only he, who could also fly, was suitable. But during the battle with Uranus, Ian was also worried that Uranus might find an opportunity to land.
Vegapunk had said that after Uranus used its Devil Fruit power, it would instinctively dissipate heat. Once it realized its body temperature was too high, it would try to land on the ground and lower its body temperature by drinking large amounts of water. This was the same as humans—when they have a fever, they unconsciously want to drink water.
If Uranus managed to land and successfully cool down by drinking water, that would mean Uranus's sustained combat capability had increased. Ian might be confident in withstanding a few of Uranus's nuclear explosion attacks, but that didn't mean he could withstand more. So limiting Uranus's sustained combat capability was a necessary task.
After restricting its landing, Ian also had to find a way to insert the forced cooling device made by Vegapunk into Uranus's body. This forced cooling device wouldn't help Uranus dissipate heat on its own; instead, it would prevent Uranus's enormous body from melting down and exploding due to loss of consciousness control when killing Uranus. In other words, before the cooling device was inserted into Uranus's body, even if Ian had an opportunity to kill Uranus, he couldn't do it.
Right now, this nail-like cooling device was being carried on Ace's shoulder. He was the second person besides Ian who could fly, so his task was to find an opportunity to enter the battlefield, cooperate with Ian, and... stuff the cooling device in!
As for the Straw Hat Pirates and Princess Shirahoshi, their task was relatively simple. After Buggy bombarded flat all the places where Uranus could land, it couldn't be ruled out that Uranus would fly close to the sea surface to drink water. Once it made such a move, Princess Shirahoshi would command the Sea Kings beneath the surface to attack Uranus! Although these Sea Kings couldn't reach too high in the sky, they had no problem near the sea surface. Their enormous size and ferocious nature were also a huge threat to Uranus. If Uranus didn't want to be dragged to the bottom of the sea by these Sea Kings, it would have to fly back up.
The battle plan was actually very simple. Buggy with Pluton was responsible for clearing the minions, Ian was the main tank holding the boss Uranus steady, Ace was the assassin sneaking up on Uranus, and Princess Shirahoshi was providing support. Although it seemed like they were missing a healer, this battle plan was still named by Ian...
As for Whitebeard Old Man and Red-Haired Shanks, they had other arrangements...
The pirate underlings of the Buggy Pirates responsible for the live broadcast were very dutifully holding the Den Den Mushi. The scene of the battle with Uranus would be broadcast to the entire world without reservation...
Before long, the outline of an island appeared in everyone's field of vision. On the Thousand Sunny, Nami confirmed the sea chart and shouted loudly to Ian and the others: "Hey! Ian, that island ahead is Uranus's hiding place! We've entered the combat range!"
Upon hearing this, Ian nodded to her, then turned back to Buggy and said: "Let's begin! Let me see the power of your special super Buggy shells!"
"It's Super Super Super Special Buggy Shells!" Buggy irritably corrected Ian, then waved his hand and shouted to his men: "Prepare for bombardment!"
"Hey-ho—hey-ho—" A sound of chanting came. About three hundred or so pirates from the Buggy Pirates were divided into three groups, each group of one hundred people, each carrying an unprecedented huge shell toward Pluton's cannons!
These three shells were not the common round shells but bullet-shaped, no different from the modern shells Ian had seen. However, the tops of the shells were also painted with Buggy's red-nosed skull mark.
Ian didn't know exactly how heavy these shells were, but the fact that one shell required one hundred people to carry it on both sides was somewhat exaggerated. But Buggy said they were made according to Pluton's cannon bore, supposedly no different from what the ancients used, so Ian didn't ask further.
After stuffing the three shells into the triple-mounted cannon bore, Buggy's men quickly moved away from the cannon position, while Buggy returned to the cabin and began adjusting the angle of the cannon in the control room.
Yes, Pluton's cannons were actually automated...
Ian and the others also moved far away from the cannon's position, watching as the cannon muzzle slightly turned, aiming at the island ahead.
A moment later, Buggy laughed triumphantly below the deck and pressed the firing button!
Boom! An earth-shattering sound came. The muzzle of Pluton's cannon spewed out a pillar of fire over a meter long. At the moment the shell was fired, a huge airburst erupted on the deck. Several pirates from the Buggy Pirates who hadn't run far enough were directly blown rolling hundreds of meters away by the airburst. As for the others, even if they were far enough away, they were still stunned by the deafening roar that could shatter eardrums.
At the same time, the moment the shell was fired, the entire Pluton hull was pushed backward by the enormous recoil...
Ian had prepared for this. When he saw the size of the shells earlier, he had already anticipated what kind of commotion there would be, so he had flown into the sky early and looked toward the distant island.
Under Ian's gaze, the island where Uranus was hiding suddenly erupted with a massive fireball at its center. The flames quickly spread across the entire island, and the trees on the island began to burn one after another.
The entire island trembled in the explosion. As countless pieces of gravel were blown into the air, the flames were also mixed with large amounts of smoke and dust rising up, looking quite spectacular.
The area affected was quite large, but Ian frowned slightly. Although such power far exceeded ordinary cannons, if it was supposed to destroy an island with one shot, it didn't seem quite right!
Unfortunately, the original shells used by Pluton had long been gone. Ian and the others couldn't replicate the real Pluton shells either. Buggy's special shells were just a substitute.
Fortunately, Buggy had anticipated this situation. So after the first shell left the barrel and hit the island, the second and third shells were also fired in succession by him!
This time, it finally looked somewhat like it could destroy an island. Ian, watching from the air, saw that as the shells continuously exploded on the island, some edges of the island had already begun to collapse.
And as the island gradually collapsed, a huge dragon roar came from the island, and a massive figure rose into the air from the island.
Ian's spirits lifted—Uranus had appeared!
So he entered his Super Saiyan state, broke the sound barrier, and flew toward Uranus's figure...
The battle to slay Uranus was about to begin...
