I'm at the top of One Piece

As time goes by.

A large tree with a diameter of ten meters appeared in front of the three of them.

As soon as they arrived, five exceptionally handsome white-necked crows with glossy feathers, sharp beaks, and claws flew over.

Moses stretched out his left arm, and one, two, three, four, five, five crows landed one after another on Moses' arm.

Each one is about forty centimeters long.

"Dumb!" "Gah!" "Dumb!" "Mei!" "Mei!"

Instantly, the five little birds looked at Mercer and began to sing in their hoarse, loud voices with varied intonation.

"Hey, crow~, one, two, three, four, five, did you five miss me?"

Five white-necked crows.

They are named Crow One, Crow Two, Crow Three, Crow Four, and Crow Five respectively. They hatched from the same nest of eggs laid by Crow Big Treasure and Crow Little Girl.

At this time,

Mercer saw that Crow Da Bao had flown back to its nest and was snuggling up to Crow Xiao Niu, whispering words of longing.

At that moment, Mercer noticed a gaze and looked up to see a figure standing at the window on the second floor of the treehouse.

Moses grinned happily.

He waved.

"I'm back, Doctor Doriel."

click!

The door opened, and a chubby black and white head poked out, its dark eyes looking at Moses with a pitiful expression.

"What? Don't you recognize me? Bear Cub?" Mercer chuckled inwardly at the sight. "Come on, let me see if you've gotten any fatter."

Xiong Bao squeezed through the crack in the door, ran over, and bumped headfirst into Mercer's stomach, knocking Mercer to the ground.

A pair of claws pressed against Mercer's chest, and a round face rubbed against Mercer's face forcefully.

Why did it take you so long to come back this time?

As he spoke, his warm tongue licked Moses's face.

Mercer held the bear cub's head in her arms and stroked its soft, black ears.

It feels better and better.

Great.

At this moment, Perona looked at Xiong Bao with bright eyes, let out a joyful "woohoo" laugh, and pounced on him.

She straddled Xiong Bao's back, wrapped her arms around Xiong Bao's neck, buried her face in Xiong Bao's fur, and sucked hard.

"A panda, it's a real panda! And it can talk? Woohoo~, I love it so much!"

Robin looked on with envy and wanted to go up and touch it, but in the end she didn't.

Bear Cub looked at Mercer, his bear face slightly embarrassed. He shook his body but couldn't shake her off. "Who is she? Can I eat her?"

"You can't eat this. It's for idiots. We're one of our own. Eating it will make you an idiot."

Mercer rubbed the bear's ears, looking at Perona who was acting like a pervert, his face showing a bit of embarrassment.

"Alright, let me get up."

Hearing Mercer's words, Xiong Bao got up and then grabbed Perona with his right paw, pulling her off.

Perona excitedly touched and pinched Xiong Bao's body, looking completely mesmerized.

……

inside the house.

I have already visited Ya Da Bao's castle space and heard about Mercer's experiences during this period.

Kureha looked at Messer with a half-smile.

It's been a while since I last saw her, and I feel that although Mercer hasn't grown taller, she seems to have gained a certain air about her.

It's probably the effect of Conqueror's Haki.

After hearing Messer's introduction of the two girls, Kureha was speechless.

The unremarkable ghost girl, Perona, didn't pay much attention.

She's just cute and has a rather rare Devil Fruit ability.

It's just so-so.

However, Kureha was now observing the remaining little girl with great interest as Robin remained silent and pursed her lips, appearing quite demure.

One or two.

He sighed speechlessly, realizing they really treated this place like a daycare.

But the thought of what I was going to do next gave me a headache.

Well, let's wait until we collect more experimental data. There's no rush.

Kureha sized up Robin, who in turn sized her up without making a sound.

Robin was relieved to find no malice in Kureha.

Through years of hard work and experience, Robin has gained some understanding of whether others harbor ill will towards her.

Kureha took a swig from a bottle of liquor, tilted her head to look at Messer, and sized him up again.

My body has gotten stronger.

"Come on, come upstairs with me. I'll give you a check-up first. Tsk tsk tsk, your 'spiritual and physical union' is quite impressive."

As he spoke, he said to the two girls, "I'll come up and draw blood from you two in a bit."

Mercer told the two of them, "Do whatever you want," and then followed Kureha upstairs to the second floor.

On the operating table.

Mercer lay flat on the bed, and Kureha pressed her fingers repeatedly on some of Mercer's breathing points.

A complete process.

He then took a syringe and drew a syringe of blood from Mercer's wrist.

We took it to a high-powered microscope and began the analysis.

He would occasionally add some oddly colored reagents, and after a moment, he wrote a form and handed it to Moses, who was sitting on the operating table.

"See for yourself."

When Mercer took a look, all his physical data were perfectly normal, even healthier than Labang in the snow forest.

but.

"The cell activity is extraordinary; it's unbelievable compared to previous data," Mercer said curiously.

“Not bad. Did your grandfather tell you about the Life Return program?” Seeing Messer nod, Kureha said with satisfaction, “The activity in your cells is comparable to that of cells in the Life Return program.”

"In other words, your current physical condition is equivalent to a permanent form of life restoration."

"You should have noticed it by now, right? Your control and dominance over your body are exceptionally clear."

"Yes, over this period of time, I've gained a stronger sense of control over my body, but it should be somewhat different from returning to life."

"Of course, it's like a light. The process of returning to life is controlled by a switch, but what you're doing now is like having no switch at all. You're in the process of returning to life anytime, anywhere, and the light is always on."

"It won't affect your health, will it?" Mercer asked curiously. "I don't feel any discomfort at all right now."

"I don't know either. Your situation is special. From what you're saying, you've had some new insights into the 'Free Breathing Method'? Spiritual breathing. You're quite amazing."

I admire you.

"Well, since you're back now, I'll just give you regular checkups during this time."

"By the way, I've deciphered the 'APTX 4869' you gave me and extracted its 'side effect,' which is the rejuvenation effect."

"However, the effects are somewhat unstable. During this time, take the finished drug, No. II, also known as 'APTX 4869II', to the island and conduct experiments on some aging animals. Remember to collect some fresh cell samples for me so I can make some adjustments."

Messer blinked, looking at Kureha with some surprise. "It's done already? That's incredibly efficient?"

"Tch, how could the efficiency not be high?" Kureha rolled her eyes. "Do you think I've lived these past hundred years for nothing? With finished products right in front of me, if I still can't decipher them, I might as well find a block of tofu and kill myself."

"Here it is."

Kureha turned around, took a bottle of red and blue capsules from the table, and tossed it to Messer.

There are ten pills inside.

There's nothing special about it from the outside.

Mercer went downstairs and brought Perona and Robin up with him.

I watched as they each had a syringe drawn from their bodies.

Perona reached out and pressed a cotton ball against the needle prick, her face contorted with misery.

Why do we need to draw blood?

Robin frowned. She wasn't afraid of injections, but she looked at Mercer with the same confusion.

"That's because your blood contains the bloodline factors of Devil Fruits."

Kureha said casually, "It has quite a lot of research value."

Robin looked at Kureha with a puzzled expression. "Bloodline factor? What's that?"

"Go ask Moses."

Kureha glanced at her and said, "Come back every two weeks for a blood test. It's not much; consider it as accommodation fees."

Robin nodded calmly.

Perona discreetly hid behind Mercer, tugged at Mercer's clothes, and turned around to see Perona with a mournful face saying:

"Can I not have it? It hurts a lot."

Moses turned around and ruffled her soft pink hair, his face cruel as he said:
