Both time-traveled characters ended up as villainous henchmen.

He Nian had speculated many times about what state a Devil Fruit user would be in after the desire that represents the fruit's power was stripped away.

Are they Devil Fruits, or gas clouds that take on the shapes of various special fruits?

Or is it an abstract manifestation of various desires?

The Devil Fruit Desire that Wapol has now extracted from him has given him an answer.

It is not only an abstract manifestation of various desires, but also shows a strong correlation with the Devil Fruit users.

The desire for the Swallow Fruit in his palm at this moment is strongly related to that of Wapol.

As for Wapol at this moment, he had already fallen into a coma.

Clearly, Wapol, as the user of the Devil Fruit, was not having an easy time after the desires of the Devil Fruit were stripped away.

He's not exactly critically injured and on the verge of death, but he should be in a coma for at least ten days to two weeks.

Moreover, He Nian could clearly sense that the "Desire" fruit in his palm was not the entirety of the Devil Fruit within Wapol's body.

He only forcibly extracted a portion, without touching the essence of the Devil Fruit.

Although Wapol will lose the power of his Devil Fruit for a period of time after waking up, he will regain the power of the Gluttony Fruit after a while, as the Gluttony Fruit in his body replenishes the missing desires.

It's even possible that He Nian's actions weakened the "desire" of the Swallow Fruit, making it easier for Wapol to enter the awakened state of the fruit later, thus doing the other party a great favor.

In contrast, He Nian now possesses this part of the "desire" of the Swallow Fruit, so he can use the Swallow Fruit's abilities to a certain extent.

It might be much less effective than Wapol's use of the Gluttony Fruit.

But if you're just enchanting a weapon, that's enough.

With this thought in mind, He Nian stopped caring about the unconscious Wapol and instead openly strolled around Wapol's palace, searching for materials that could be used to forge swords.

He wasn't planning to kill Wapol, mainly because of the Swallow-Swallow Fruit.

In He Nian's view, the Swallow Fruit's ability is very useful. It can devour and absorb all matter and then synthesize new materials. In a sense, it can also be considered to have a kind of growth potential.

If this characteristic were applied to weapons, it would save him the trouble of running all over the pirate world searching for a suitable famous sword.

While there are many famous swords in the world of One Piece, these swords are divided into different levels, and different levels of strength require different levels of swords.

He Nian remembered that Zoro, a member of the main character group, had changed quite a few swords.

He didn't think his luck could compare to that of the protagonist's group, who was designated as the world's greatest swordsman, especially since he now seemed to be targeted by the world's rules in the pirate world.

Secondly, and more importantly, He Nian himself possesses the power of "infinite evolution".

Although he is not yet able to fully channel it and apply it to external objects.

However, if we use the "shell" of the Gluttony Fruit's power, it will be much easier.

In this way, even if he encounters some supreme grade sword later, he can directly feed these swords to his own sword, completing another round of upgrades and evolutions.

This fusion of abilities from different worlds is clearly not something that can be accomplished completely in one go, so Wapol still needs to live.

If he really dies, it will probably take him a lot of effort to find the next user of the Gluttony Fruit.

He Nian strolled around Wapol's palace as if no one else was around.

Even though the palace guards noticed He Nian, they only exchanged a glance before lying down and falling into a peaceful sleep.

Not long after, He Nian found many suitable materials for forging swords in Wapol's palace.

Because of the properties of the Swallow-Swallow Fruit, Wapol can swallow anything, which also makes his appetite abnormal.

Therefore, his palace contained many metal materials that Wapol considered "delicious" to be used as snacks.

After closing the palace gate, He Nian arrived at the pile of selected metal materials.

The next step, sword forging, is crucial and cannot be interfered with by others.

Even though he had already used Conqueror's Haki to knock everyone in the palace unconscious, they would be in a coma for at least eight hours.

But just to be on the safe side, he still sealed off Wapol's bedroom.

Furthermore, Wapol's palace had already been upgraded and modified by him using his Devil Fruit ability, making its defenses far superior to those of ordinary buildings.

After a brief period of meditation, He Nian gathered the selected metal materials into a pile, then took out the "Desire" fruit, which he had been holding in his hand with Conqueror's Haki. After carefully connecting it with his mental will, he pressed it onto the pile of various metals in front of him.

Upon contact with the pile of metal materials, the giant, pale purple maw seemed to trigger some underlying code, opening its jaws wide and beginning to devour everything in its path.

In just a few breaths, a pile of metal materials weighing over two hundred kilograms was completely swallowed by the giant-mouthed Devouring Fruit "Desire".

However, the original "desire" aura did not show any significant change in size.

On the contrary, within its body, one could faintly hear the metallic friction of various materials fusing together.

With his mind focused, He Nian quickly strengthened his mental connection and silently enhanced his innate domineering aura. With his powerful will, he suppressed the "desire" of the Devouring Fruit and reversed the direction of its consumption and transformation according to his own will.

After a brief stalemate of a few minutes, He Nian emerged victorious.

Driven by his "desire" to devour the fruit, he began to forge the sword according to his design.

Seeing that the sword-making process was on track, He Nian quietly breathed a sigh of relief.

Next, and most importantly, he carefully separated the unique evolutionary "desire" hidden within him, belonging to Agumon and Pikachu, and incorporated it into the sword-forging process of the Munch-Munch Fruit "Desire".

In this process, he needs to suppress the "desire" of the Swallow Fruit while keeping it running according to the established plan.

At the same time, it is also necessary to carefully peel away the evolutionary "desire" that lies hidden within oneself.

Next, it is necessary to control the integration between the two.

This process cannot tolerate the slightest distraction or mistake. Even though He Nian has made great progress in controlling his mental will and spiritual power, he cannot guarantee that he will definitely succeed.

After slowly exhaling, He Nian began to act.

While suppressing the "desire" of the Gluttony Fruit, he separated the "desire" for evolution from within his body.

This process alone lasted nearly two hours.

The subsequent fusion process took more than four hours to complete.

Only after everything is completed can the final step of sword forging begin.

Fortunately, at this point, He Nian no longer needs to expend too much effort.

He Nian was panting heavily, her whole body was soaked as if she had been washed with water, and she even seemed listless.

His physical and mental strength, as well as his reserves of innate domineering energy, were greatly depleted during this process.

The difficulty of fusing his own evolutionary "desire" with the "desire" of the Gluttony Fruit was somewhat beyond his imagination.

Fortunately, they held on in the end.

"Now, we just wait for the sword to be finished."

He Nian stared at the ball of desire in front of her, which was intertwined with thunder and fire, and her tired eyes shone with anticipation.
