There were many mountains on Drum Island, and there were two ways to climb them.
One was to climb up with his own ability, and the other was to pay a sum of money and take the cable car to the top of the mountain.
Aiur and Nami both had the ability to bring Carina and Lina up the mountain, but they had already saved up one billion Berries, so they would not be reluctant to spend such a small amount of money.
After handing over a thousand-dollar bill to Barry, Aiur and the others took the cable car to the top of the mountain.
In front of them was a castle that stood on the snow and emitted an ancient aura.
This castle had at least a few decades, or even a hundred years of history.
The owner of the castle was a 129-year-old witch.
A hundred years old was nothing to the Giant Tribe.
However, for ordinary humans, even mutated humans like White Beard and Charlotte Lingling, it was already very old.
As for Kureha, not only did she live to 129 years old, even after another ten years, she was still a Demoness who looked energetic and fierce.
To be able to live to this age, Kuleha must have her secret to immortality.
Perhaps she had drunk the 'medicine' that she had created to survive until now.
No one knew what level Kuleha's medical skills had reached in the past hundred years.
However, one thing was for sure. One Piece's ship doctor, Kulokas, was definitely like a younger brother to Kuleha.
If she was willing to teach Ai Er how to make the nutrient serum, then the nutrient serum would definitely be the most advanced existence in the world.
There were three types of doctors on Drum Island. The first type was not famous enough, and they either worked as interns in hospitals built specifically for doctors in Drum Kingdom or were ordinary doctors.
The second was a famous doctor who had already become famous and only treated privileged people.
The third option was to not work in the hospital and open a 'small clinic' somewhere else on the island to treat the 'fated person' who was a quack or a famous doctor.
Kuleha was the third type.
Although the name " Witch " was very famous on Drum Island, except for some older people who knew how amazing the medical skills of the " Witch " were, no one else would seek treatment from Kuleha.
Because Kuleha had been semi-retired for many years, she would not steal the business of the younger generation until she was the only doctor left on Drum Island.
In addition, Kuleha's fees were very high, even more outrageous than the famous doctors in the hospital.
Therefore, there were very few people in this castle, and it was very quiet.
Dong Dong Dong
Arriving at the castle gate, Aiur knocked on it.
"Come in, the door isn't locked."
An old and powerful voice sounded from above the door.
Glancing at the trumpet-shaped microphone above, Aiur pushed the door open and walked in. Then, he walked toward the aura that Wen Se had sensed.
Along the way, no one came to invite Aiur.
'As expected, I'll be 130 years old soon. How can an old monster who has experienced countless eras not have the domineering aura of Wen Se?'
Sensing that the aura hadn't moved at all, and through his ability to see through people's minds, he realized that the owner of the aura was also surprised. Aiur knew that Kureha was also a domineering powerhouse.
Perhaps, before Locks 'father was born, he had already gone out to sea to adventure.
"When you see the doctor later, remember not to call her mother-in-law.”
As if remembering something, Aiur suddenly reminded Carina and the other two girls in a low voice.
"Yes, yes."
Although they didn't know why Aiur said that, Carina and the other two girls still nodded obediently.
Dong Dong Dong
After a while, Ai Er came to the door of a room and knocked on the door again.
"Come in."
The old and powerful voice sounded again, but this time it came from the inside out.
"Sorry to disturb you."
Ai Er said politely and pushed the door open.
As soon as they entered, they saw a scene that looked like a laboratory with complicated instruments everywhere.
In front of a device stood an old lady who was dressed fashionably and had a pair of sunglasses on her forehead.
Seeing this old lady, if not for Aiur's reminder, Carina and the other two girls would have blurted out subconsciously,""What a fashionable old granny."
Fortunately, they didn't say anything except for their red lips.
"Hmm? It's actually so small!"
Kuleha, who was fiddling with the liquid in the test tube, subconsciously glanced at Aiur and the others.
When she saw that the aura sensed by Wen Se Ba Qi was actually a young man with baby fat on his face, a trace of surprise appeared on her wrinkled face.
He had awakened the domineering aura of sight and hearing at such a young age. Could it be that he was born with the domineering aura of sight and hearing?
And with this level of physical fitness, where did this little monster come from?
Kureha, who was full of doubts, did not ask directly.
However, what she was thinking in her heart could not be hidden in front of Ai Er's ability to see through people's hearts.
Aiur was surprised by this.
As expected of a hundred-year-old monster. Just by finding her location with the Aura of Knowledge, she guessed that he had the Aura of Knowledge and even thought of the Innate Aura of Knowledge.
Was this an old monster who had eaten salt and walked more than him?
Aiur, who was shocked, bowed respectfully to Kureha.""Hello, Senior Kuleha. My name is Aiur. I came here to ask you for advice.”
"Ask me?"
The corners of Kuleha's lips curled up slightly, and he subconsciously said his own catchphrase,""Do you want to know the secret to my eternal youth?”
"Um."
Ai Er was slightly stunned, then he put on an honest child's face and said,"" I'm only eight years old this year, and I don't need the secret of eternal youth yet. I'm here to ask you how to make 'nutrition serums' so that our bodies can develop in advance in a reasonable way and quickly realize our talents.”
" A 'nutrient agent' that allows the body to develop reasonably ahead of time. I didn't expect you to have such thoughts at such a young age."
Kureha's eyes lit up, and then he looked at Aiur meaningfully.""I thought you were already twelve or thirteen years old. I didn't expect you to be in such a state when you were only eight years old. You've already developed ahead of time.”
"Yes."
Ai Er nodded honestly.
"I can teach you, but my fees are very expensive.”Kureha agreed readily.
"I know."
Aiur took the only box that wasn't deposited into the bank from Carina's hands. He opened it and said to Kureha,""Is 100 million Barry enough? If it's not enough, please give us some time. I'll go out and collect the money!”
"Little wimp, you remind me of two little ghosts who were very active on the sea decades ago.”
Looking at the box full of cash, Kuleha looked deeply at Aiur again, then glanced at Carina and the other two girls standing on Aiur's left and right."If I didn't see so many cute little girls around you, I would have thought that you were like that lonely little brat.”
After saying that, Kuleha looked away and continued to fiddle with the test tube in his hand."100 million is enough.”
"Thank you, Senior."
Aiur bowed again, then led Carina and the other two out of the room and gently closed the door.
Through his ability to see through people's minds, Ai Er also knew who the two little brats Kureha was talking about were.
One of them was Charlotte Lingling, and the other was the Lonely Red, Baloric Redfield.
He even knew the characteristics of these two people. He was indeed an old monster who hid his strength!
