Deep-sea immersion silver: Immersion silver under the deep seabed is squeezed by the pressure of seawater all year round, and the original huge volume of immersion silver is constantly compressed and condensed, becoming extremely dense, and a small piece of immersion silver is worth several tons of silver.

The Deep Sea Immersion Silver in the quest reward is a very unique metal, and although it is only the size of a thumb, it weighs thousands of times more than ordinary silver.

Lu Yuan polished this small piece of deep-sea immersion silver into a ring and put it on Van Gufried's ivory, the polishing method is very simple, just use a lightsaber, after all, the upgraded lightsaber can cut through everything.

"Aang!"

With a weight of several tons, Van Gufried's face suddenly changed, although he could lift the weight of the deep sea sinking silver with his strength, he would inevitably feel a little uncomfortable.

Lu Yuan slapped the elephant's buttocks, and scolded in his mouth: "Don't pretend to me, I know that your strength is more than this, the elephant fruit is a symbol of strength, and the power of a thousand jun is not a problem at all." ”

After being beaten by Lu Yuan, Van Gufried stood up with an aggrieved face, twisting his head with difficulty, and the silver ring on the ivory "tinkling", although it was heavy, it was still within his bearing.

"Turn me into a sword!" Lu Yuan said fiercely.

Frightened by Lu Yuan, Van Gufried was suddenly stunned, he knew that this person was powerful, and he could only give in.

After turning into an elephant sword, the silver ring hangs under the tip of the sword, blessing all the weight on the sword, plus the weight of the elephant itself, making the sword extremely load-bearing.

Because the elephant sword has its own independent consciousness, which is equivalent to a special life, and the strength of the elephant is very large, the weight of the entire elephant sword is borne on Van Gufried.

In other words, Van Gufried's own strength was enough to support the weight of the elephant sword, and the person holding the elephant sword would not be crushed by the weight of several tons.

Lu Yuan gave this weighted version of the elephant sword to Kan'er, and forced Van Gufried to confess his lord again, although he was very reluctant, but he had to obey due to Lu Yuan's obscenity.

"The name Van Gufried is too cumbersome to pronounce, and you will be called ...... in the future Da Zhuang, yes, your name is Da Zhuang. ”

Lu Yuan secretly said that he was really talented, and he could think of such a beautiful name.

Although Van Gufried looked helpless when he heard his new name, he still did not dare to have the slightest opinion, for fear of being cleaned up.

Kan'er swung the elephant sword twice violently, and the air was smashed to a whirring, which was equivalent to a multi-ton giant being wielded, and the power can be imagined.

Even so, the weight that Kaner could feel was only one or two hundred catties, and the rest of the weight was added to Da Zhuang's body, after all, Da Zhuang was enough to lift several tons of items.

Not only is it heavy, but the elephant sword can also be freely retracted and can be transformed into an elephant at any time, just like the "ivory assault" used by Spandam, the tip of the sword can be transformed into an elephant's head, and then use the ivory to arch at the enemy, which is very powerful.

With this powerful weapon, Kan'er's combat power also soared in an instant.

In this way, the strength of the crew has increased a lot, except for Robin, who is not loyal, and Kulokas, who does not participate in the battle.

"Everyone is ready to prepare, and tomorrow, we will start to attack the city." Lu Yuan said.

Advance City is a large undersea prison, which holds the world's most vicious pirates and countless felons, built on the bottom of the sea, and outside the prison is the murderous sea kings, and there is no escape.

Unless you take a warship made of sea building stone, even if you escape from prison, you won't be able to survive under the territory of the Sea King.

Therefore, once imprisoned in Advance City, there is no possibility of escape, of course, there are exceptions, that is, the protagonist Luffy and the Golden Lion Shiki.

But these are not important, the important thing is that Lu Yuan is here, then the history here will be rewritten.

……

The next day, Lu Yuan and his party were already fully prepared, so they marched in the direction of the city, here is a windless zone, there are countless sea kings, fortunately, the Jiaolong is inlaid with a large number of sea building stones, so there is no need to worry at all.

Seeing that it was approaching the Advance City, the Jiaolong did not dare to continue to advance.

The overall strength of Advance City is much stronger than that of Justice Island, once discovered, even the current Jiaolong Pirates will be difficult to retreat from the whole body, after all, the warden of Advance City is infinitely close to the strength of the general level, and it is not an exaggeration to say that he has the strength of a general.

"Cutros, Kailin, Kante, the three of you will act with me, and the rest will wait on the ship, acting as soon as the opportunity arises."

Lu Yuan took out the Hailoushi submarine and let the three bulls go up first.

Then he pondered for a moment, and felt that it was still necessary to hide the Jiaolong, although it was now parked in a relatively hidden place, but who could say for sure that it would not be discovered by the navy.

Lu Yuan stood at the bow of the boat and took a deep breath.

“ROOM！”

Lu Yuan stretched out his right hand, borrowing Trafalgar Rowe's signature moves, and an independent space stretched out from his hand, containing the Jiaolong.

This is his ability, as a person with the ability of space fruits, it is not a problem to create an independent space.

This space is rooted in the void, blending into heaven and earth, it is difficult for outsiders to perceive his existence, even if someone passes by here, they will not find that there is a small space world in the void.

"Where heaven and earth are, is space, all the substances in the world exist in space, space and time, is the origin of the world, in charge of the operation of all things in nature, this is the power of the fruit of space."

Lu Yuan was extremely excited in his heart, this was the first time he had used the spatial ability, of course, this was not enough to show the strength of this ability, and in the future, Lu Yuan would gradually show the true power of this fruit.

He stepped out of this separate space and jumped onto the submarine.

"Huh...... What about the ship? ”

Kanter emerged from the submarine and looked at Lu Yuan with a puzzled expression.

"I relied on my fruit ability to hide the ship!"

Lu Yuan smiled, then entered the submarine, closed the hatch, and controlled the submarine to sink slowly.

Since this submarine is made of sea building stone, it can avoid the eyes of sea kings and will not be detected.

"Are you the mighty? Why didn't we know before? Kante asked, surprised.

Kailin and the bull also looked at Lu Yuan.

"I found a Devil Fruit from Spandam, so I became a powerhouse!" Lu Yuan explained.

As the prefect of CP9, it's not surprising that Spandam has a Devil Fruit on him.

"I see, what kind of ability is it!"

"Space!"

Keltros Niu looked puzzled: "What is the Spatial Fruit?" I've never heard of it. ”

"You haven't heard much of it." Lu Yuan rolled his eyes.

"Yes!" The bull smiled awkwardly.

Lu Yuan changed the topic: "I'm going to dive into the prison from the bottom of the sea, I'm all seated, and I'm about to go." ”

"Under the sea?" Kante was shocked.

"I've heard that the Advance City is an impregnable wall, how can you get in from the bottom of the sea?" The bull also questioned.

"Just follow me!"
