One Piece : Marine Scientist

Looking at such a powerful Seraphim, Sengoku smile was almost splitting his face.

With such a formidable Humanoid Weapon, how could their Marine not grow stronger?

If they could develop more, they could sweep away all pirate forces across the seas with overwhelming force!

Thinking of this, Sengoku eagerly turned to Leon.

"Leon, since this is a Seraphim, then the Admiral-level Seraphim could also be mass-produce, right?" His eyes were filled with anticipation.

"Fleet Admiral, theoretically, it is indeed possible, but we need a sufficient supply of blood samples!" Leon shook his head.

"However, the blood sample from Kaido we collected last time has already been used up, we can't even produce one more."

Upon hearing this, a look of regret appeared on Sengoku's face.

"So it seems that to create an Admiral-level Seraphim, we need a continuous supply of blood samples? And they must be from strong individuals, right?"

At that moment, Akainu had already reached a ceasefire with Sakai, who had been halted by Leon, and came over to their side.

He happened to overhear Sengoku's words.

"Then let's go find Kaido!" Akainu suggested with a fierce grin.

"It doesn't matter who, as long as we have blood samples from a person at the level of the Four Emperors, then we can create another Admiral level Seraphim" Leon shrugged.

"Wait a minute!" Garp suddenly interjected, laughing.

"Did we forget about the sixth level of Impel Down? There are many notorious criminals there, some of whom are not any less formidable than the Four Emperors!"

"Are you talking about Bullet and the Redfield?" Sengoku's eyes lit up instantly.

Indeed, both Bullet and the Redfield possessed personal strengths that could be considered on par with the Four Emperors.

And they were both within their territory, making it much easier to collect their blood samples!

"Great! Let's head there right away!" Sengoku's face was filled with joy as he immediately led Leon towards Impel Down.

Just then, mechanical voices echoed in Leon's mind.

"Ding, Admiral-level Seraphim development successful!"

"Reward obtained: Seraphim - Yonko level development technology!"

"Reward obtained: Ultimate Cloning Technology!"

"Technology has been stored in the host mind, the host can view it in detail at any time!"

He felt a surge of joy.

A Yonko-level Seraphim!

This was even stronger than the Admiral-level!

He quickly checked in his mind, but then he froze.

A look of astonishment crossed his face.

"This Yonko-level Seraphim is indeed impressive, but the cost of development is just too high!"

He learned in his mind that developing a Yonko-level Seraphim required a staggering one hundred billion Berries! That was an exorbitant cost.

"Let's take a look at the Ultimate Cloning Technology next!"

In the next moment, his expression turned to shock.

"Just one strand of hair can make a clone?! This is the Ultimate Cloning Technology?!"

Leon was utterly stunned.

To possess such a means could already be called a divine act.

However, the cost to complete this technology was also immense.

To create a clone, the various materials would cost at least ten billion, not counting other expenses, Leon estimated it would total at least over twenty billion.

"Ding, new mission released!"

"1. Successfully create a Yonko-level Seraphim;"

"2. Successfully clone one person."

Leon sighed inwardly.

Both of these technologies should not be easy to achieve!

"Leon? Why are you still dazed? Let's go!" Sengoku urged with a smile.

"Oh, coming, coming."

****

Along with Sengoku, Garp and the three Admirals, Leon arrived at Impel Down.

Of course, the Seraphim Sakai, who closely followed Leon, was also with them.

"Fleet Admiral Sengoku, Garp-san and Admirals, what brings you to Impel Down today?"

A gigantic man, resembling the legendary Satan, stepped forward.

It was none other than the warden of Impel Down, Magellan!

He approached and nodded in greeting to Sengoku and the others.

At the same time, he noticed a strange young man and a child about eight years old accompanying them.

"Magellan, let me introduce you; this is our Marine's genius scientist, Leon!"

As soon as these words were spoken, Magellan body trembled slightly and a look of surprise appeared in his eyes.

"This is Leon? I didn't expect him to be just eight years old, just as the rumors said!"

Since the Seraphim had been invented, Magellan had heard the name Leon repeatedly.

After all, he was the creator of the Seraphim, a Humanoid Weapon even more powerful than the Pacifista.

As a genius scientist who surpassed even Vegapunk in this regard, Leon name was naturally well-known.

"Yes, that's him."

"I can't believe that at such a young age, he was able to invent a Seraphim with the combat power of the Shichibukai, that's truly remarkable!" Magellan expressed his astonishment. 

Leon smiled slightly and nodded in acknowledgment.

Sengoku shook his head. "No, Magellan, your information is outdated. We have now developed the Admiral-level Seraphim."

"What?!" Magellan's eyes widened in shock.

An Admiral-level Seraphim, what did that mean?

It meant the Marine's top combat power was about to increase!

"Haha, Magellan you are lucky, today marks the birth of the Admiral-level Seraphim and he is here with us."

"Hmm?" Magellan was momentarily taken aback.

Then he looked at Sakai.

'So he is the Seraphim!' He hadn't thought of it before and since this person was standing behind, Magellan naturally hadn't scrutinized him closely.

But now, he noticed that this young man possessed the racial traits of the Lunarian Tribe.

However, unlike the Seven Warlord-level Seraphim, he seemed to have an extra pair of horns.

Looking at his face, Magellan furrowed his brow, why did this face look so familiar?

"Wait… isn't this?" He looked at Akainu in surprise.

"Hmm, yes, it's my appearance when i was a kid. This Admiral-level Seraphim was created using the bloodline factors from both me and Kaido." Akainu nodded in acknowledgment and Magellan suddenly understood.

No wonder! No wonder he had a pair of horns like Kaido.

"So what brings you here this time…"

"We need to collect blood samples from individuals at the level of the Yonko" Leon's youthful voice rang out.

Magellan was taken aback, his expression slightly tightening.

"You mean you want to collect blood samples from Bullet and the Redfield?"

"Exactly!" Sengoku nodded with a smile.

"Alright, I'll lead you there, but those two are not easy characters to deal with…" A look of caution flashed in Magellan's eyes as he spoke slowly.

"No worries, let's head over first." Sengoku furrowed his brow but soon relaxed.

No matter what, they would face whatever came their way!

If they didn't cooperate, they would just have to make them cooperate..... by force.

With that, Leon and his group quickly made their way to the sixth level of Impel Down…
