Fast! Observation Haki! Fast!

In the sweltering cell, the two "skull" instructors watched the Pirate World Fang Yu sweating profusely, expressing utter bewilderment.

They were just betting on each other for fun at first.

One might think that a kid with no bounty couldn't possibly learn Observation Haki.

One of them, however, felt that he could definitely do it.

And so, the two made a bet, without even placing any stakes, and began their fierce competition.

However, after two days, the two of them had long since stopped taking the matter seriously.

Meanwhile, Pirate World Fang Yu was still diligently digesting the knowledge the two had shared.

Fang Yu had read the original story about Silvers Rayleigh teaching Luffy. Although that part of the story was rather mundane, he still remembered a few key scenes.

By combining the learning experiences of his two fellow inmates, he actually came to some insights.

Especially Ugo Bennett, who studied Observation Haki for eight years before mastering this technique.

The techniques he mentioned were all based on experience!

Compared to Rayleigh's method of teaching Luffy, that was far more practical.

You have to know that Luffy is a monstrous genius who can replicate almost all of CP9's Six Powers with just one glance.

Fang Yu didn't think he could master Observation Haki as easily as Luffy.

After resting with his eyes closed for a while, Pirate World Fang Yu opened them and asked, "Gentlemen, would you like to try attacking me?"

"Are you kidding me? Here? It's hot and I'm hungry!" Hugo Bennett was the first to object.

Heran Carlson, who had kicked Fang Yu, shook his head vigorously, saying, "You don't need to take this to heart. Learning Observation Haki is of no use to you."

"Do you think you can get out of this airtight cell just because you've learned Observation Haki?"

Pirate World Fang Yu chuckled, reached out at the scorching railing, and stuck his fingers out. "Where is it completely airtight?"

"This kid, I was just giving you an example." Helan Carlson rolled his eyes at Fang Yu. "You can't even get out of this cell, let alone the labyrinthine Impel Down. Just getting from the Starvation Hell to the Beast Hell is a challenge."

"Do you think that over the years, only Golden Lion has tried to escape? There have been many, but only Golden Lion managed to get away."

"So, put your mind to it, kid." Helan Carlson gave a wry smile and shrank into a dark corner.

Hugo Bennett tilted his head back. "The guards will distribute some Hiramishi tomorrow night. Save your energy; if you keep moving around, the water from that Hiramishi will disappear quickly."

A memory flashed in his eyes, "If you don't want to end up like my former cellmate, dying from dehydration."

Fang Yu exclaimed in surprise, "Oh? The jailers even provide meals?"

"Of course, they only want to torture us, not kill us. If they did, they would have executed us long ago. Why would they go through all this trouble to put us in jail?"

"That's true."

By Impel Down, the probability of Devil Fruit appearing in the world can be greatly reduced.

Without Devil Fruit, people would lose most of their ways of gaining power.

Then the World Government's rule will be even more secure.

Leaning against the wall, Heran Carlson glanced at Fang Yu, who showed no sign of stopping his exercise. "Give up your thoughts. Even if you manage to escape Impel Down, you'll still face the Calm Belt, countless Sea Kings, and warships chasing you."

"If you had that ability, you wouldn't have been brought here."

"Perhaps you're right," Fang Yu took a deep breath, "But the me of seven years ago is not the same person as the me of now!"

"In addition."

"If you two don't report me, I can even satisfy your craving for water for a short period of time."

Neither of his two skeleton cellmates responded to his words.

Because Fang Yu's arms were Seastone Handcuffs!

Even if Ability User, how can they activate their abilities while wearing handcuffs?

"He's gone mad, he's gone mad from being locked up! It's only been a few days, and he's already gone mad," Holland Carlson sighed. "Poor thing!"

Yin!

Si!

Hugo Bennett also looked regretful, "This kid is indeed talented, but he's not very bright. If I had been locked up in Impel Down when I was seven, I would have broken down long ago."

Son!

Si!

Fang Yu Hand Seal, Heran Carlson asked curiously, "What are you doing?"

As the last Yin Seal was formed, Fang Yu slapped the ground!

"Water Release · Water Wall!"

A powerful stream of water shot up from the ground like a fountain, carrying the two skeletal prisoners to the ceiling of their cell!

The force of the water was strong, and it hit them directly on the head with a dull thud.

The two prisoners were so disoriented by the sudden flow of water that their heads hit the ceiling, and they saw stars.

However, even though they were still in a daze, their bodies reacted instinctively to the sudden appearance of the water source!

Their lips pressed greedily against the water, gulping down the precious moisture!

Water streamed down their faces; they drank and swallowed like travelers who had found an oasis in the desert.

With each swallow, Hugo Bennett and Herran Carlson's throats bobbed, and satisfied expressions appeared on their faces!

As the water flow gradually weakened, the two prisoners slowed their movements, but they were still unwilling to give up until the last drop of water was greedily sucked into their mouths.

Their bellies were slightly swollen from drinking enough water, and their faces showed a long-lost sense of satisfaction and peace.

Judging from their expressions, it wouldn't be an exaggeration to say they had just done fifty attempts.

"You burp~" Helan Carlson burped. "How, how did you do that?"

Hugo Bennett patted Carlson's stomach, "No matter how he did it, we, we can't tell anyone about this!"

"Of course!" Hugo Bennett wasn't stupid either. Given the choice between licking the jailer and being able to drink water Tenten, he would naturally choose water.

"Don't get too excited yet," Fang Yu explained. "This water only provides a feeling of fullness and can also moisten the mouth, but the water will still disappear from your bodies after the time is up."

The water generated using chakra will disappear as the user's chakra is depleted.

The Shinobi World understands this principle, but these two pirates certainly don't.

They were content with being comfortable now.

"Well then, you two."

"Isn't it time to impart all your skills to others?"

Ugo Bennett saluted. "I'll risk my life to teach you Observation Haki!"

Helan Carlson sat up straight. "Me too!"
