Pirate: I have a Hollow living inside me

Of course, Rocks couldn't give up.

Rumble ball was another reason he came here.

He wondered if the effects of the Rumble Ball could work on him.

If possible, how would you present it?

"Well……"

Chopper was actually a little tempted.

After all, he was the only one who had ever used the Rambo Ball after it was made.

I wonder if it will work on other Zoan-type Devil Fruit users...

However, after thinking about it, Chopper shook his head, firmly defending his bottom line as a doctor: "No, I'm a doctor, I can't give other people unstable medications!"

Locus: "..."

I admire your professional ethics as a doctor.

But you don't have to be so stubborn!

"Don't be so stubborn. Drugs need clinical trials, right? Without experimental subjects, the effectiveness might not be so accurate..."

After much persuasion, coaxing, and deception,

It was only after Roxne's arrival that Chopper's thinking began to soften...

However, Chopper decided to ask Kureha's opinion first.

Kureha, who was teaching Little Illusion medicine, heard about this and, confirming that Rocks was determined to do so, said, "Since he proposed it, why don't you let him try it, Chopper?"

"However, the dosage needs to be carefully controlled to prevent a recurrence of your previous condition. If he were to 'go berserk,' this island could be destroyed..."

Previously, research on this drug, Kureha, was strictly prohibited for Chopper.

However, the little guy was still secretly trying.

Left with no other choice, Kureha had to let Chopper do his research.

However, some restrictions were set, and it can only be done under the premise of ensuring safety.

Furthermore, Rumbleballs have an even more serious side effect: if the dosage is too high, Chopper will turn into a mindless "monster"...

Even Chopper is terrifying when he goes berserk, so imagine if the "Blackwing Demon" Rocks went berserk...

Then Drum Island might be completely destroyed...

"Will this island be destroyed?"

Chopper was startled, then nodded emphatically: "I understand, Doctor Doriel, I will control the dosage!"

Afterwards, Chopper solemnly led Rocks to the outside of the treehouse...

Not only Rocks came along, but also Kuina, Nami, and Robin.

As for the others...

Little Yi is still learning from Kureha.

Yixiao went to the casino in the island town.

Wapa and Lachi were also interested in everything about Qinghai. This was the first time they had ever seen snow, so they strolled around the island...

……

At this point, Rocks and his three companions were taken by Chopper to an open area.

"I named this drug Rumble Ball. It is a kind of transformation wave that can interfere with Zoan-type Devil Fruit users."

Chopper picked up the Rumble Ball and bit into it, saying to the others, "Eating it will cause animal-type ability users to develop other transformation forms."

"This is wrist strength enhancement... this is leg strength enhancement... this is fur enhancement... this is horn enhancement..."

Chopper ate a Rumble Ball and then demonstrated the different transformations.

'Pat pat pat...'

Rocks clapped his hands and exclaimed, "Amazing!"

Nami was very surprised: "There are four different transformations now, and the feeling they give me has changed. My aura seems to have become stronger!"

Robin stroked his chin: "It's amazing. I didn't expect there to be such a special drug. It creates different states, which is quite useful for Zoan-type Devil Fruits."

Kuina nodded: "You're amazing, Chopper, to be able to develop this drug."

"Hehe, it's not that impressive!"

Chopper, who was maintaining his enhanced horns, started to wriggle again when he heard the fishy words, his face full of embarrassment.

One minute later, the effect of the Rumble Ball disappeared.

Chopper transforms back into his tiny humanoid form...

"The effect of the Rambo Ball lasts only one minute, and the side effects are severe, causing aches and pains similar to those experienced during exercise."

"Moreover, you can only take one pill. Taking a second pill will cause uncontrollable symptoms and will worsen the body's aches and pains."

Chopper stretched his slightly sore body. He then explained that the poison would cause someone to lose their mind, enter a "berserk" state, and become a monster that only knew how to destroy!

The Rumble Ball is not yet perfect.

The duration of action is too short, and the side effects are too strong.

This is not a normal drug.

It still needs further improvement!

"..."

Upon hearing this, the three women present, apart from Lox, fell into a strange silence.

Subconsciously, he looked towards Rocks...

Will it go berserk?

Will it turn into a monster that only knows how to destroy?

Isn't this exactly what Rocks told them before?

Is it just another coincidence?

Rocks didn't pay attention to the three women's expressions, but smiled at Chopper and said, "Can I have one to try?"

"Okay, but be careful. Don't be too reckless. If anything unusual happens, you need to tell me immediately!"

Chopper reminded him and handed a Rumble Ball to Rocks.

"I won't do anything reckless."

Rocks smiled.

After receiving the ball, he examined it carefully.

A faint medicinal smell wafted from the tip of my nose; it smelled slightly bitter, not like candy.

I imagine the taste of Rumble balls probably isn't very good...

He didn't pay attention to the taste either, and ate several of the different flavors of Devil Fruits. The medicinal taste was within Rocks' tolerance range.

'Snap!'

Rocks put the Rumble Ball into his mouth.

With a snap of his teeth, he crushed the Rumble Ball, the bitter taste of the medicine exploding on his taste buds, before swallowing it...

As Rumble Ball was swallowed, Rocks discovered that it had transformed into a source of energy.

Moreover, the quantity is considerable, comparable to the energy obtained by Rocks from a large meal.

'It actually turned into energy?'

Lox was surprised by this.

I didn't expect it to turn out like this.

Moreover, even if the effects of the Rumble Ball and the medicine have no effect on Rocks.

The energy contained within alone would be of great help to Lox.

It can temporarily replenish energy!

This was of great use to Lox.

It can extend Rocks' time... Don't overthink it, it extends the time of his "ethereal" state!

"Wh...how is it?"

Chopper was a little nervous.

This was the first time he had given a Rumble Ball to someone else, or rather, another ability user.

I don't know what might happen to others.

For ordinary people, it doesn't have any other effects. Kureha also tried taking Lamboballs, but they were just a bitter "health supplement"...

"I don't seem to feel anything? There are no other changes in form either..."

Lox checked his body.

Aside from the addition of an extra source of energy, nothing else had changed...

Rocks couldn't help but ponder: 'Could it be that the Human-Human Fruit in human form is special?'

"Perhaps the medicine isn't strong enough?"

Rocks came up with a reason and looked at Chopper: "Give me another one to try, okay?"

"Okay, fine."

After thinking for a moment, Chopper handed over another Rumble Ball.

Taking a second Lamb Ball is fine; although the side effects will be more severe, it won't cause you to "go berserk"...

Rocks swallowed the second Rumble ball.

The Rumble Ball transformed into energy once more, and Rocks' body was now brimming with energy. This time, Rocks also noticed another change...

'Om! '

The energy within his body began to flow uncontrollably, forming a dark green energy cloak that flickered like flames on Lox's body.

This is the second stage of the ethereal transformation!

Lox: "?"

Uncontrolled activation of the second stage of etherealization?

Could the Hollowfication state be another way to exploit the "distorted wavelength of Zoan-type Devil Fruits"?

No.

It should be said that "disrupting the distorted wavelength of the Zoan-type Devil Fruit" is a kind of energy distortion.

He's already ahead of us?

Looking at Rocks, whose body was covered in a dark green flame, Chopper looked puzzled and surprised: "Eh, what is that?!"

Why did the other person change like this?

Rocks, finding himself unable to control this state, explained to Chopper, "This is one of the abilities of my Devil Fruit, a weakened version of the state you saw before."

Chopper, being a doctor, made his own assessment of the situation: "You...you've been able to control the distorted wavelength of your abilities for a long time?"

"I don't know if this is the same wavelength you mentioned that controls the animal system's deformation, but this ability is controllable for me."

Rocks clenched his fist: "It's just that the effects of the Rumble Ball drug have made me unable to control this form right now."

"Apart from the fact that it can't be turned off, everything else seems exactly the same as when I turned it on myself..."

Indeed, it's not much different from when he activated the second stage of Hollowfication.

It just can't be turned off by itself.

It was interfered with by the medicinal properties, or rather, the energy, of the Rambo Ball!

Chopper: "..."
