The walls around the island are printed with large X-1 characters, indicating the name of the great fortress of the Navy.

I have to say that the speed of the Navy's military construction projects is indeed amazingly fast.

Among the sappers, those who have the ability to specialize in construction are very strong, which greatly accelerates the speed of military construction.

This is also the reason why Don was able to see the general appearance of the fortress in just a few days here.

"I have to say that the productivity of the pirate world, with the assistance of the Devil Fruit, has been greatly enhanced."

"In some ways, even beyond the planet."

In the previous life, on Earth, in terms of attack, there were powerful nuclear bombs and various firearms. But the Devil Fruit ability of the Pirate World, the three-color domineering, the way of the sword, cultivated to the extreme, the destructive power will not be inferior to the nuclear bomb. Of course, to talk about the effect of expelling the dose is to play hooligan.

In terms of the level of destruction, the two sides are actually not much different.

The difference is that the earth is a large-scale operation and will compete in terms of comprehensive strength, while the pirate world is a single combat capability.

"However, in terms of construction, with the assistance of Devil Fruits, this speed cannot be compared to the earth!"

Don sighed.

He stood on the shore, looking at the towers rising from the ground, the closed fortress buildings, and his heart could not help but admire.

The speed is not bad, and the quality is also guaranteed.

Devil Fruit is such a technical means, put on science, it is no longer inexplicable, just like a void creation, which basically puts the law of conservation of energy on the ground and tramples on it.

Heavy fog has always shrouded the island, and under this natural cover, the actions of the navy are not afraid of anyone detecting it.

Chances are, when the fortress is fully built, the pirates will have a huge surprise.

Standing on the wall of the city, which was more than 100 meters high and like a tall building, Tang En felt the solid feeling under his feet, and his heart was shocked again.

"It's really terrible, no matter how many times I watch it, my heart will be shocked."

Such a city wall, in terms of quality and defensive power, is more powerful than the city wall of China in the previous life. Also, the super strong man in the pirate world, the single attack power is too perverted, and it can be called a catastrophe.

Seeing the huge buildings rising from the ground like this, getting bigger and bigger day by day, and getting grander day by day, there is no one who is not amazed in their hearts.

In Don's opinion, this rear admiral's fruit ability is even similar to the Thousand Hands Pillar in the Hokage, which can create a world by himself.

"How? Don boy, having a Rear Admiral Crete in the navy is equivalent to having countless castles. ”

"In order to find this fruit, the navy took considerable effort."

Karp said with a smile as he stood on the rampart, looking down at the sea in front of him.

Don let out a breath, feeling once again in his heart the greatness of the navy's forces and the strength of its advantages over the pirates.

Becoming a pirate is not as cheap as the navy, and you can use all kinds of resources.

In the navy, within the world government, if you do well, even the superiors can find the right fruit ability for you. They have the world's resources at their disposal and have unimaginable conveniences.

As for the pirates, they can only hope for illusory luck.

"As long as we give us more time, when the fortress is completed, the pirates will have no choice but to take us!"

Karp said as he looked at the drifting mist.

Tang En nodded silently, and had to admit that the construction of the X-1 Fortress this time was closely related to the climate, if it weren't for the dense fog that lasted for several days, I am afraid that such a big action would have been detected by the Golden Lion and Whitebeard Pirates.

At that time, it will be impossible to judge what kind of measures these two forces will take.

In the blink of an eye, five days had passed since the Navy had taken control of the island.

After five days of fog, a gust of sea breeze swept through and finally began to disperse, and the sun shone happily, illuminating every inch of the island.

Donn, Karp and the others, at this time, stood on the walls surrounding the island.

Looking out, three hundred meters away from the island of Saine, there are still three circles of towering walls.

They stood in the ocean like that, showing an incomparable momentum and majestic aura. This is the most advanced construction technology of the Navy in this era, surpassing the world's top, and it also symbolizes the Navy's control over the world's power.

Whether you look inside the island from the outside or look at the sea from a high place, you can feel suffocated.

This huge fortress, like a colossal monster standing on the sea, exudes a heavy majesty like a mountain, intimidating enemies from all directions.

"Although it was very urgent, fortunately, before the fog dispersed, the city walls and gates had been successfully built!"

Sweeping the sweat from his forehead, Major General Crete came to everyone with a smile on his face.

There was a look of exhaustion on his face, and in order to rush the work, the major general had not slept for five days and five nights, and he was dedicating his strength to his abilities.

"It's hard work, I'll leave the rest to us, Major General Crete, you have a good rest."

Facing this great hero, Karp said in a serious voice.

"It's time for me to rest, but before I rest, I still want to see what I've done during this time."

"You know, this fortress is like my child, it has been reborn, and I, as a father, naturally want to see it."

As he spoke, Crete came to the city wall, and in the sea breeze, the top of his head shook and trembled, and the cloak of justice behind him fluttered violently.

"How?"

Tang En saw that the other party was stunned and couldn't help asking.

"What a beautiful boy!"

"I'm satisfied!"

Crete was smiling and satisfied.

Then he slowly closed his eyes and fell limply, followed by a thunderous snort.

"He's so tired!"

Don was stunned for a moment, then waved.

"Take Major General Crete to rest and take good care of him."

Dorrens and the others stepped forward quickly, carefully picked up Crete, and walked towards the navy's resting place.

On the ramparts, Don and Karp were still standing, looking out to sea.

Around the city wall, there was already a navy garrison. The walls on the sea are also densely armed.

The mechanisms and weapons on it have already been placed, and at this moment, the X-1 fortress and the external defense project can be said to have been roughly completed.

The rest, that is, when Crete wakes up, continues to fill the facilities on the island.

But with these walls and gates, the X-1 fortress has become a refuge for the navy and a hideous war machine.

"I'm looking forward to it now, Whitebeard and Golden Lion, the faces of those two guys when they learn that we have unknowingly arrived at their territory."

Karp said with a sudden smile.

"I'm looking forward to it, too."

Donn smiled.

His gaze looked across him, and he remembered the crescent-shaped white-bearded fellow.
