One Piece: The Cryo Doctor on the Straw Hat Ship

"It was my first time performing surgery, and I was so focused that I completely forgot about Nami."

"She should have been on that cruise ship at the time. If we had just tied her up, we wouldn't have had to live in such fear."

However... you can run away from the monk but not the temple.

Knowing where Nami's hometown is, V isn't worried that they'll miss out on this exceptionally talented navigator.

It is rare to see races other than humans in the East China Sea, the weakest sea in the world.

He was really looking forward to the prosthetic bodies that these fish-men could transform into.

Especially the ability to breathe underwater...

"You can't get fat in one bite; you have to take it one step at a time."

V focused his attention on Coby in front of him.

With a thought, the robotic arm immediately placed the breathing mask on Koby's face and released an appropriate amount of anesthetic.

Overwhelmed with anxiety and unease, Koby quickly closed his eyes.

Blue light flashed in V's prosthetic eye, and data streams poured down like a waterfall, displaying Koby's physical condition in real time.

[Patient: Koby (human)]

[Energy Level: Tier 1]

[Physical condition: Long-term severe malnutrition, resulting in incomplete physical development.]

Treatment recommendations: Administer plenty of intravenous fluids and engage in moderate exercise.

However, at that moment, an unfamiliar notification suddenly popped up beside Koby's body:

[A special destiny carrier has been detected; its body can be sold for a high price on the black market or transformed into a special prosthetic body.]

"A special destiny vessel? My expectations were definitely not in vain!"

A playful smile instantly appeared on V's lips.

He knew that the mighty deserter king wouldn't let him down.

Judging from the anime, Koby's talent is undoubtedly world-class.

Compared to Luffy, Zoro, and others who have trained since childhood, Coby's path to growth is truly one of being surrounded by an aura of glory and utterly unreasonable.

He was kidnapped at sea at the age of 13 and worked as a servant on a pirate ship for three years.

Influenced by Luffy, he suddenly gained willpower and worked 200 times harder, surpassing others in a lifetime in just two and a half years.

In terms of talent alone, his performance may even surpass that of Zoro, Sanji, and others.

At only 18 years old, he was able to fight against the executives of the Four Emperors of the New World.

This resume surpasses that of 99% of the world's top performers.

But now, this extraordinary body has fallen into V's hands.

"I wonder if this is my good fortune or your misfortune?"

V grinned, revealing a meaningful smile.

The next moment, he directly opened the [Cyborg Shop].

Back in the afternoon, he had already divided Alvida's body into pieces and exchanged them for 800 trading points on the Black Market.

Although the process was somewhat cruel, V believed that striking down bad people was a way of helping good people.

Therefore, he felt perfectly justified in taking the money.

"So... first of all, the foundation of cybernetic modification is..."

V's eyes darted around quickly, and she soon found her target in the store:

Brain-Computer Interface Patch

[Level: 1]

[Description: Basic neural interface. It allows data to be accessed into the user's nervous system, enabling the installation and manipulation of prosthetics; it is an essential component for prosthetic users.]

Price: 100 Trading Points

……

Military-grade training chip

[Level: 1]

[Introduction: Basic Training Module. This module implants combat techniques and physical training programs via neural links, assisting users in quickly mastering basic combat, weapon use, and physical enhancement methods. It is suitable for beginners to get started quickly.]

Price: 100 Trading Points

……

After exchanging the two items using a quarter of the trading points, a silver metal piece immediately appeared in V's hand.

The patch was only the size of a fingernail, its surface covered with fine lines, and it gleamed with a cold blue light.

"Join the glorious evolution, Koby!"

A stream of data flashed through V's eyes as he handed the brain-computer interface patch, which incorporated a training chip, to the robotic arm.

Under his control, the robotic arm precisely parted the hair on the back of Koby's neck, exposing the skin above his cervical spine.

The patch adheres silently, with countless tiny probes extending from its edges to pierce the subcutaneous nerve bundles.

hum-

Kobi's body trembled slightly, but he did not wake up under anesthesia.

In V's field of vision, Koby's neural signals unfolded like a spider web, quickly establishing a connection with the patch.

[Brain-Computer Interface Patch - Installation Program Started]

[Neural interface connection successful]

[Synchronizing the basic prosthetic control protocol...]

[Completed simultaneously]

[Military technology training chip loading...]

Almost simultaneously, Koby's eyelid twitched slightly.

His brain was passively receiving a massive stream of information—basic fighting stances, weapon handling techniques, physical enhancement breathing methods, reaction speed training modes...

This knowledge is not forcibly instilled, but rather imprinted directly into neural circuits in the form of "muscle memory".

After Koby regains consciousness, there will be a teaching trial to help him fully adapt to his new body.

"This way, you'll be able to easily control these prosthetics."

V walked towards the prosthetic display stand and took down the Iron Fist prosthetic from the top.

[Iron Fist - Basic Strength Enhancement Prosthetic Body (Tier 2)]

[Effect: Slightly improves arm strength and grip strength]

These prosthetic arms were originally transformed from Alvida's arms.

Although it's only a basic enhanced version, it's the perfect starting equipment for Koby at the moment.

Blue light flowed in the V-shaped eye, and the robotic arm quickly entered working mode.

The sharp scalpel flashed coldly under the light, precisely cutting into Koby's wrist joint.

Because the anesthesia was still in effect, Koby did not feel any pain; however, on a neurological level, he could vaguely "perceive" the access of some external object.

The robotic arm moves swiftly and precisely, separating bones, connecting nerves, linking blood vessels, and fitting prostheses... each step is as fluid as art.

[Neural connection in progress...]

[Vascular connection complete]

[Prosthetic stability test...passed]

[Iron Fist Prosthetic Body Installation Completed]

[Experience points +150]

Current experience points: 250/1000

The surgery ended about ten minutes later.

V's experience points increased significantly again.

It's clear that, according to the system's assessment, the benefits of prosthetic modification far outweigh those of treating injuries.

At this moment, Koby's originally slender and weak arms have been replaced with a pair of slightly thick metal prosthetics.

The prosthetic body has a matte dark gray surface with subtle blue veins flowing at the joints. The fingers are flexible, and the palms are covered with a non-slip synthetic material.

"Basic adaptation complete."

V nodded in satisfaction, then manipulated the robotic arm to completely remove Koby's hands, which were thin and calloused from long-term malnutrition.

"Next, it's time to verify our conjecture."

With a thought, V reopened the [Black Market] interface.

[Materials detected: Human hands (Quality: Special)]

[Transforming...]

"Special quality!?"

V's eyes lit up, and the corners of her mouth, which had been suppressed by the surgery, turned up again.

With a thought, he directly chose to exchange for a prosthetic body.

A few seconds later.

[Conversion complete!]

[Achievement: Effort Leads to Success (Tier 3)]

【Effect: When equipped, the training effect can be increased by at least ten times when the user is practicing and has sufficient nutrition.】

This effect can be stacked with other similar prosthetic components; for each additional component, the effect is increased by an additional 50%.
