The only way to recover is to use the power of a healing fruit.

Some kind of healing fruit ability?

No, it's a level higher than that, it may involve the conceptual ability of regenerating a broken limb.

Yes, in Zephyr's eyes, the ability to regenerate a broken limb must be at the conceptual level.

Because even the most recognized natural fruit ability user in the sea may lose a part of his body in battle and cannot use his ability to make up for it.

For example, Aokiji, whose leg was broken by Akainu, and Ace, who was pierced, are in this situation in the original work.

In addition, Zephyr's ship was almost completely slaughtered at that time.

There was no devil fruit ability user with healing ability on board!

He could only rely on his own practice of life return to keep the wound active. As for the arm that had been broken, there was nothing he could do.

So even if Vegapunk later personally operated and modified the frozen broken arm, there was no way to help him 100% restore to perfection.

But at this moment, Xia Chen seemed to have used some kind of ability, and several steel structures drilled out of his arm, and then the wound began to heal, and it was numb and itchy.

After a while, a long-lost sense of smoothness came to my heart, and Zefa unconsciously clenched my fist, and then it became more and more powerful. There was a crisp sound of bang bang bang.

Xia Chen stepped back a little and watched Zefa experiment, and then his arm was covered with a thick layer of armed color, and the color became darker and darker, especially on the wrist.

The former black-armed Zefa is back!

"This... is completely restored."

Zefar was shocked, and Aokiji also understood the situation of his teacher.

"I think you should be quite satisfied with your arm, so I didn't help you generate a new one, otherwise you would have to exercise." Xia Chen said, and it also completely confirmed that he had the conceptual power of broken arm rebirth.

Zefa pursed his lips.

He glanced at the seastone weapon that fell to the ground and said, "Thank you!"

His voice was dry, but it could be heard that it was sincere. Noticing his gaze, Xia Chen glanced at it and saw that the broken seastone weapon floated up automatically. Under the incredible gaze of Zefa and Aokiji, it was reunited again.

"This!"

The ability of the fruit cannot work on seastone. This is the consensus of the sea.

Currently, only the craftsmen in Wano Country have mastered the seastone processing technology.

But what happened to Xia Chen?

Zefa couldn't wait to hold it with both hands, observed carefully, and found the reason. Xia Chen didn't restore the seastone to its original state, but another very delicate metal made them come together. It's just that the assembly is very delicate and generally can't be seen.

This is not bad!

Xia Chen is not that outrageous, and there are still means to restrict him.

Although it was a bit ungrateful to have such an idea at this moment, in fact, the two of them still adhered to the justice of the navy in their bones!

Xia Chen then set his eyes on Aokiji, thought about it, and really didn't know what he could give to the other party. Then he looked at his remaining suits, um... there was no suitable one.

So.

Xia Chen closed his hands, then slowly pulled them apart, and a metal blade appeared in his palm, then slowly extended, and finally turned into a nine-ring machete nearly two meters long.

The whole body was dark black.

This is the so-called black knife.

Although for unknown reasons, Xia Chen could not combine the armed color domineering with this lv2 level chaos skill, but if he pushed the two abilities at the same time, it would have no effect on him.

So Xia Chen directly integrated his armed color domineering into it during the manufacturing process.

Zefa and Aokiji were also people who had seen the world. Seeing this scene, they couldn't help but open their mouths.

According to their understanding, the black sword is made by using armed Haki and years of continuous tempering, integrating power into it bit by bit, and it often takes several years or even decades to make it.

But Xia Chen actually did it directly.

This is simply not in line with common sense.

After Xia Chen finished it, he gently waved it twice, making a fierce sound of breaking wind.

"It's okay!" Then he handed it to Aokiji.

The latter took it subconsciously, but such a big sword was not suitable for his combat system, but he especially wanted to see what the difference was between this black sword and the rumored black sword.

Then he infused his Haki.

There was a clear sense of blockage, and as he infused more Haki, the whole blade trembled violently, a little
It means out of control.

Xia Chen looked more carefully, and he could feel the call of this knife to himself.

At this moment, Xia Chen truly understood the meaning of the black knife. No wonder the black knife is the most suitable for him only when he forged it himself.

It's like a soul given to a dead object... domineering, will, soul!

Hey, this seems to have something to do with the devil fruit, after all, some dead things can eat devil fruits.

Especially the common ones of the animal system.

So the relationship between the two is really just a completely opposite relationship?

After this thought flashed through his mind, it was suppressed by Xia Chen. He looked at Aokiji who was fighting against the dark machete in front of him, and said: "Your domineering is still a little short of the fire. When you can master this knife, it means that your domineering has improved a step. Come on, young man."

Then he disappeared from their sight in a flash.

Aokiji twitched his mouth: young man?

I am more than twice as old as you, but this kind of person is really scary.

"Teacher Zefa, have you ever seen a black knife made directly?" Aokiji said, but he didn't hear a reply for a long time.

He turned his head and noticed that Zefa's eyes were always staring at the direction where Xia Chen left.

Although they didn't even see how the other party left before, they knew that as long as Xia Chen was in the Abyss of the Dragon King, he would stay in the palace of Hancock, the Queen of Nine Snake Island, most of the time.

"Kuzan, do you think there are really gods in this world?"

Aokiji was stunned.

He paused for a moment and understood what the other party meant.

After all, the means that Xia Chen has shown so far are outrageous.

He seems to be not much different from a real god. At least even Aokiji himself began to doubt whether he could really beat the other party by just piling up people?

Controlling water, soil and wind, remaking metal, and regenerating the body... Unless it is a mythical beast species, the "God" fruit, it has such rich abilities!

Besides.

In their concept, most Devil Fruit users have the ability to develop to the upper limit.

Except for some extremely outrageous abilities, so far they have seen only one person who has developed the fruit ability to the conceptual level.

Tyrant Kuma, one of the current Seven Warlords of the Sea.

He has developed this fruit ability to an unprecedented level. This fruit ability has appeared before, but they only used it for defense and rebound at most.

But in Kuma's hands, fatigue, injury, and even memory can be ejected.

Theoretically speaking, it can also be explained from the microscopic perspective of neurons and synapses, but in fact, it is unreasonable to explain it with this scientific concept.

So fruit development cannot only take the scientific path!

It depends on the imagination!

But the "fruit development" course inherited by the Navy does not say so. They emphasize "reasonable and well-founded" and "scientific and reasonable", and they also know that Kuma's conceptual skills were developed with the assistance of Vegapunk!

The Navy has had thinking limitations from the beginning!

Just like Aokiji, he felt that his ice fruit gave him a very high starting point. The elementalization of the representative natural fruit itself is a semi-awakened ability.

But how to develop it next, lower temperature? A wider range?
