Sailing: His comprehension is against the sky, and he comprehends the Eight Gates at the beginning.

"We must acquire the power that can replace them and obey our commands unconditionally as soon as possible."

After a brief discussion, the group unanimously agreed to Satan's proposal.

Soon, Satan Saint, acting as a representative, made a phone call to Vegapunk.

When Vegapunk heard that Satan Saint wanted to activate that thing ahead of schedule, he immediately exclaimed in surprise and refused.

"no!"

"Seraph is currently in the testing phase!"

"There is still a lot of data that is uncontrollable, and there are too many unknowns."

"Moreover, they are still too young. If we accelerate their growth in order to force them to participate in the war, it will cause irreparable damage to their bodies."

"They are the most powerful humans I have ever researched for the future."

"I cannot risk letting them perish on that kind of battlefield before they have even grown up."

Faced with Vegapunk's stern refusal, Satan said coldly.

"I'm not discussing this with you, Vegapunk!"

"The current situation is not optimistic."

"The loss of four Shichibukai is a huge weakening of our strength and will also affect the future world order."

"We urgently need a strong fighting force to fill these gaps."

"And think about it carefully..."

"If the navy suffers too heavy losses in this battle, do you think you'll still have enough funding to continue your research?"

Satan's words left Vegapunk speechless.

He was only looking at the issue from a researcher's perspective, so he was unwilling to let the Seraphim join the battle prematurely given the many uncertainties involved.

But as Satan said, if the navy really suffered heavy losses or even lost the war, then he would no longer have the funds to continue these studies.

After struggling internally for a long time, Vegapunk finally gritted his teeth and reluctantly agreed to Satan's request.

"All right!"

...

Nine Snake Island!

In the forest!

"Dad, are you going to the deep-sea prison?"

Kuma had originally planned to say goodbye to Luffy and the others.

Before saying goodbye, Bonnie asked Bear about his next plans, only to learn that he wanted to go to the Deepsea Prison first before returning to the Revolutionary Army.

Upon hearing Bonnie's question, Bear nodded and said...

"Yes! One of my friends in the Revolutionary Army has been captured and imprisoned there!"

"I want to rescue him and go back to the Revolutionary Army's base with him!"

Upon hearing this, Luffy immediately realized that Kuma was probably referring to Ivankov!

Bonnie, however, spoke with a worried expression.

"But isn't that where the navy detains criminals?"

"There must be a lot of defenders, right?!"

"Dad, it's too dangerous for you to go alone!"

Seeing Bonnie's worried expression, Xiong gently patted her head and said softly.

"Before I came here, I received news that [Fire Fist] Ace had already been taken to Marine Headquarters!"

"It is said that the Navy was afraid that Whitebeard's crew would break into Impel Down ahead of time."

"If a battle were to take place there, the most heinous criminals imprisoned there might be released by Whitebeard's crew, becoming an unpredictable factor that could affect the course of the battle."

"So if I go there now, I won't encounter many enemies."

"Once the war breaks out, the navy won't be able to provide support!"

"At that time, if I were to take action again, I would only need to deal with the guards there."

Despite this, Bonnie still looked very worried and said.

"But it holds the world's most heinous criminals, so the guards there must be very capable!"

"Dad, it's too dangerous for you to go alone!"

Faced with Bonnie's worries, Xiong was at a loss for what to do.

This is the best chance to rescue Ivankov. If the war ends, rescuing him from there will require the support of the entire Navy Headquarters.

Even if he manages to contact the Revolutionary Army, they won't have enough fighting force to get here in such a short time.

Just when both Kuma and Bonney were in a dilemma, Luffy suddenly spoke up.

"Let's go together!"

Kuma was quite surprised to hear Luffy's words.

Bonnie, on the other hand, looked delighted.

She didn't want to see the bear saddened by watching its friend being captured without being able to rescue it, but she also didn't want the bear to be in danger.

So Bonney was very happy when she heard Luffy say he was willing to help.

"Really, Luffy?"

Bonney's eyes sparkled as she looked at Luffy with anticipation.

Luffy smiled slightly and nodded as he looked at Bonney.

Upon seeing this, Bonnie beamed with joy and expressed her gratitude.

"Thank you, Luffy!"

Kuma, looking puzzled, asked Luffy.

"why?"

"You guys are going to rescue Ace, right?!"

"If we waste time there, we might miss the opportunity."

Luffy smiled and shook his head upon hearing this, and said...

"Do not worry!"

"We'll make quick work of it."

"And there are things I want to do there."

If nothing unexpected happens, Jinbe is also currently imprisoned there.

If Jinbe isn't rescued, he might never get out of here for the rest of his life.

There's also something Luffy cares about.

That means Blackbeard and his crew are very likely to go there as well.

Leaving Blackbeard unattended would not only increase his fighting power, but Jinbe might also be killed there.

So it's still worth Luffy's trip there.

Besides that, Luffy has another thing he wants to experiment with.

That is, he wanted to test whether Franky could obtain the power of the Barrett Fusion Fruit.

Judging from the original work, Franky has shown a certain talent for fusion.

·· ····Requesting flowers···· ·

For example, when he first joined the Straw Hat crew, he showed off the humanoid combiner robot to the Straw Hat crew on Thriller Bark.

Later, they even developed General Franky, who could combine with others.

From these perspectives, it is possible for Franky to acquire this powerful Devil Fruit ability.

Upon hearing Luffy's words, Kuma stopped making excuses.

After seeing Luffy in his Nikka form, he and Bonney already had an unconditional trust in Luffy.

Afterwards, Luffy trained with the Straw Hat crew for two more days, helping them improve further.

With Luffy's extraordinary comprehension, Usopp and his two companions have become extremely proficient in mastering their awakened abilities.

During this time, the Empress also announced to the people that she would be joining the Straw Hat crew and that Marigold would temporarily take over as the new emperor.

Although the public was initially surprised when they learned of this news.

But in the end, after Luffy and Boa Hancock explained to them the dangers that Hancock's withdrawal from the Seven Warlords of the Sea would bring to the island, and that Luffy's flag would protect the island, they accepted the decision.

After hanging the Straw Hat crew's flag on Amazon Lily and bidding them farewell, Luffy led the Straw Hat crew, along with the newly joined Empress and Kuma, towards Impel Down under Kuma's guidance.

...

Two days flew by.

With Vivi and the Going Merry taking turns moving forward, Luffy and his crew finally arrived at Impel Down on the day of their execution.

Looking at the sea fortress so close at hand, Xiong said calmly.

"It's six o'clock in the morning!"

"Ace's execution time is 3 PM!"

"If we can get to the Navy Headquarters from here, we'll need to take advantage of the Navy's exclusive ocean current."

... .... 0

"Based on the speed of the Merry, it will take less than an hour to arrive."

"Therefore, we have a maximum of eight hours."

To ensure Vivi's stamina, the bear used the speed of the Going Merry for calculations.

Upon hearing the number, Luffy nodded and said...

"enough!"

With Karu around, they can easily move up and down the prison in a straight line, which will save them a lot of time.

All they need to do is defeat the guards and find the people they need to save.

There was absolutely no discussion of tactics.

Upon arrival, Luffy and his crew charged straight in.

At this point in time, Whitebeard could appear at any moment, and the Navy is unlikely to send anyone to provide support.

When Luffy and his crew appeared in the sight of the guards at the prison gate, they were immediately terrified.

The Straw Hat crew, together with two Shichibukai, what an incredible fighting force!

Soon, the alarm in the guard room blared throughout the entire prison.

"Enemy attack! Enemy attack!"

"Attention all!"

"The Straw Hat Pirates, former Shichibukai Bartholomew Kuma, and Boa Hancock have been spotted at the main gate of the prison. All guards, prepare for battle immediately."

"Attention all..."

Luffy originally planned to just kill whoever he saw.

But upon hearing the announcement, he was overjoyed and temporarily let the guards go.

If we keep them around, the news can spread throughout the entire prison.

When Ivankov heard the news, he took the initiative to show up.

This will save them a lot of time.

Just as he had predicted.
