Traveling through the universe, starting with obtaining the Marvel Ten Rings

"who are you!?"

Most people on the Golden Merry had never seen Nico Robin.

But Luffy showed a surprised look: "Hey, why are you on the ship?"

"Luffy, do you know her?"

"Well, she's with Crocodile's gang."

"What!?"

In an instant, everyone was ready for battle.

Zoro has already drawn his sword and pointed it at Nico Robin: "Are you here to avenge Baroque Studios?"

"Wow...what a beautiful girl." Sanji's eyes had turned into heart shapes.

Just then, another arm sprouted from Zoro's arm and slammed Zoro's sword to the ground.

"Don't point something that dangerous at me."

"When did you get on board?" Nami looked at Nico Robin warily.

"I've been here since I escaped from the Royal Prison in Alabasta."

"what do you want to do?"

"Let me be your companion." Nico Robin sat on the chair on the deck, looking at everyone in a lazy but elegant posture.

"what!?"

"Great, we're going to have another beautiful lady on board."

It’s clear that no one except Sanji can trust Nico Robin.

"Why did you come to our ship?" Luffy asked.

"Because I'm homeless." Nico Robin replied.

"Oh...Is that so? That can't be helped."

"Hey, Luffy!" Everyone was speechless at how easily Luffy agreed to Nico Robin's joining.

"haha……"

At this moment, Rosen came out of the cabin.

"It looks like we have a new companion." Rosen smiled kindly.

Nico Robin's hair stood on end in an instant. Her original elegance and composure disappeared completely. She stood up from the chair abruptly, while unconsciously stepping back.

"You... why are you here?"

"Of course I'm here. After all, I'm the vice-captain of the Straw Hat Pirates." Rosen said angrily, "As a newcomer, you should learn to respect your seniors, asshole."

Nico Robin is very clear about how terrifying the old man in front of her is.

Crocodile was as docile as a little lamb in front of this old man.

Such a powerful guy is actually the vice-captain of a small pirate group.

"Master, do you know her?"

"Of course, my last name is Luo, and hers is also Luo, so we are relatives." Rosen said: "According to seniority, Robin should be considered my granddaughter."

"Hey, my last name isn't Luo!"

"Hmm?" Rosen's kaleidoscope activated instantly.

A second later, Robin knelt on the ground, cold sweat pouring down.

"I'm sorry, my last name is Luo, grandpa."

"Okay, let's start today's special training. Robin, you come too." Rosen looked at Robin and said, "Looking at your thin arms and legs, I know you didn't eat well before. You have to make up for it in the future."

"The weather is so nice today, can we take a day off?" Luffy said weakly, "Besides, we have new companions joining us, so we must celebrate."

"The celebration can wait until the evening."

"But……"

Staring! A second later, Luffy instantly curled up on the ground.

"I have improved the method of training Armament Haki. You all must memorize it. If you still haven't memorized it before the sun sets, I will smash your skulls."

Rosen then repeated the method of cultivation: "How much have you remembered?"

"I didn't remember a single word." Luffy replied.

"10%." Zoro.

"30%." Sanji.

"50%." Chopper.

"60%." Usopp.

"80%." Nami.

"I remember all of it," Robin replied.

"Oh?" Rosen turned and looked at Robin.

Robin regained his composure and smiled back, "What's the problem, Grandpa?"

"No, except Luffy, you are responsible for making sure everyone else remembers it today," Rosen said.

Luffy has the best talent, but his brain is not meant for storing things.

As for asking him to memorize 300 words of cultivation method in one day, that is absolutely impossible.

"Wahaha... Grandpa, do I not need to study anymore?"

"No, I'll let you study in the Tsukuyomi space."

"Ah... Old man, I will study hard, please don't send me into the Tsukuyomi space."

Even Luffy, who is fearless, is afraid of the Tsukuyomi space.

"Haha... your promise is totally untrustworthy."

Days on calm seas are a little dull.

This period of time is just the best time for them to practice.

"Come here, little cat."

"Damn old man, I'm a reindeer, a reindeer! Not a raccoon!" Chopper is no longer afraid of Rosen.

“Would you like to learn something else?”

"Will it make me stronger?"

"Of course, maybe he can become the strongest in the Straw Hat Pirates."

Chopper immediately looked at Rosen with shining eyes. In his mind, he was already imagining a scene where their Straw Hat Pirates encountered a powerful enemy, and then Luffy, Zoro, and Sanji were defeated. At this time, he stood up alone, fought with the powerful enemy for three hundred rounds, and finally saved his companions.

"Grandpa, can I learn too?" Robin came over with a smile on his face.

After two months, Robin can now call Rosen Grandpa fluently.

"You don't have the qualifications."

Robin's eyes were a little dim. Was he really being excluded?

Rosen added: "But I can teach you the same Five Elements Escape Technique as Nami."

Rosen took out a chakra test strip and handed it to Robin.

After checking, he said, "Yin, Yang, water, fire, wind, thunder, and earth! Oh, it's surprising that you have all the attributes."

At this moment, Rosen opened the distorted space.

Although it was just a small opening, Robin and Chopper both saw that the space was filled with twisted limbs.

Where is that? Hell?

Rosen took out a pair of sealing scrolls for the three-magatama Sharingan.

"Would you like to get a new pair of eyes?"

"Change eyes?" Robin looked at Rosen in surprise.

Rosen's eyes opened the three-magatama Sharingan: "These are the eyes."

"These eyes? Are they the eyes used to cast illusions?"

"These eyes are not only used to cast illusions," Rosen said. "They have powerful dynamic vision and can continue to evolve, just like mine."

Rosen displayed the Kaleidoscope, the Eternal Kaleidoscope, and the Rinnegan.

"You possess extremely rare all-attributes, so you have a chance to evolve these eyes to the level of the Rinnegan."

"What's so special about the Rinnegan?"

"Powerful, of course. It also has some special abilities. You will understand what those abilities are when your eyes evolve to that level."

"Okay, I'll change." Robin made the decision.

The next moment, Robin felt a pain in her eyes, and then she fell into darkness.

"Ah... old man, how could you do this to Robin?"

Chopper's shout attracted everyone.

When they saw the bloody holes in Robin's eyes, they were all shocked.

"Robin-chan, what's wrong with you?"

"Robin-chan had his eyes gouged out by the old man."

"Master, what did Robin do wrong? Why did you do this to her? She is our companion."

"You old bastard, how dare you do this to Robin-chan? I will never forgive you." Sanji was the most annoyed.

"Shut up, everyone." Rosen glared at everyone, took out the Sharingan, stuffed it into Robin's eye sockets, and then began to use the Palm Fairy Technique to heal Robin's eye nerves.

After a few minutes, Robin finally regained his sight again.

There was a bit more awe in his eyes when he looked at Rosen.

"I can see it."

"Hey, Robin, your eyes are so special." Luffy looked at Robin's three-magatama Sharingan in surprise.

Robin was still trying to adapt to this new pair of eyes. She could clearly feel that her vitality was being sucked away by this pair of eyes.

Rosen cut open his palm and stretched it in front of Robin.

"Drink my blood."

"Ah?" Robin was a little at a loss.

"These eyes are not something that ordinary people can control. My blood can help you adapt to them faster."

Robin hesitated for a moment, but still took Rosen's palm and put it to his mouth.

Rosen's blood did not have the bloody smell that Robin thought it did. She even felt a hint of sweetness.

The blood did not enter her abdomen. After entering her abdomen, she felt the blood seemed to evaporate in her mouth.

The stinging sensation in her eyes gradually disappeared.

Just then, Luffy exclaimed, "Ah my... Robin's eyes have become like the old man's."

Because of absorbing Rosen's blood, Robin's eyes have begun to evolve into Mangekyō Sharingan.

Robin immediately understood the power he had just gained.

"Keep going, suck until your eyes evolve to the next stage."

Robin held Rosen's hand and nibbled it for half an hour, and finally the kaleidoscope in her eyes began to spin rapidly.

Then the lines in the eye sockets became more obscure and complex.

Rosen then withdrew his hand: "How do you feel now?"

"Grandpa, I feel like your blood is still in my body and has not been completely absorbed."

"Of course, after all, that's my blood." Rosen said, "Let's find a small island nearby."

"Master, what are you going to do?"

"Subdue the monster for Robin."

"Subdue the monster? What kind of monster? Where is it?" Luffy has turned into a curious baby.

"You'll know when we get there."

Coincidentally, there was a large island not far from them.

After the Golden Merry docked at the edge of the island, everyone went aboard.

"This looks like an empty island, no one lives here."

"Right here." Rosen stood still and looked at everyone: "Next I will release the monster, you need to subdue it."

Rosen released a Shukaku that was fifty meters tall.

The moment Shukaku, the one-tailed beast, appeared, everyone was shocked.

Roar--

"Go ahead, why are you just standing there? Use all your strength to defeat it."

This One-Tailed Shukaku is considered a weakened version of the tailed beast, and its strength is half that of the One-Tailed Shukaku in the Naruto world.

It has a disadvantage, which is that it cannot grow.

Rosen planned to give Robin a Ten-Tails, but this Ten-Tails did not have the growth potential of the Ten-Tails.

Rosen can split into countless Ten-Tails. After all, for Rosen, as long as the origin of the Ten-Tails is not split, a Ten-Tails can be split out every now and then.

Of course, except for the lack of growth, it has all the effects of the Ten-Tails, such as huge chakra and super high chakra recovery speed.

But the current Robin is not strong enough to subdue the Ten Tails, so Rosen plans to split the Ten Tails and give them to Robin one by one, starting with the simplest One Tails.

Robin stood beside Rosen: "Grandpa, what is this monster?"

"It's called Shukaku, the One-Tailed Beast. In the future, it will be sealed in your body. There are nine such tailed beasts in total. When the nine tailed beasts merge into one, they will merge into the Ten-Tailed Beast. At that time, your eyes will evolve again. However, this requires you to master your current eyes, my blood, and control the nine-tailed beast."
