I travel through countless worlds at the same time

But Yuu Higashino in the Harry Potter world doesn't know these magics, so they don't know them either.

This is also the same in other worlds. The theory of idol worship can only be used by Yuu Higashino in the world of Toaru Majutsu no Index. Borrowing magic power from other gods casually is also a feature of the Marvel world.

Therefore, if one wants to obtain spiritual energy through other worlds, only Higashino Yuu from the Little Garden World can do it.

Even if other people can provide help, it is only auxiliary and they cannot help with the key steps.

Although they are the same person, they are different individuals.

This is determined by the overall environment and cannot be changed by them alone.

"It seems to be the case. So I'd better just lie down and relax." Higashino Yuu from the Detective Conan world thought for a moment and nodded.

His limit is there! It's useless even if he wants to work hard!

"Wait! If you go back this time, please bring me a copy of Conan's suits. You can't be unable to get these things!"

Suddenly, Higashino Yuu in the box-shaped world thought of something.

Although there are people with powerful gifts in the community of the Little Garden world, there are also some children. These things of Higashino Yu are prepared for these children.

"Just preparing that? No problem. No, it's easy."

Higashino Yuu from the Detective Conan world smiled upon hearing this.

These things may be difficult for others, but they are really nothing to him.

Ever since his assets reached a certain level, he began to invest in the technology industry with a targeted approach, and Dr. Agasa was naturally his first investment target.

After all, not to mention those strength-enhancing shoes or trackers and anesthetic guns, the solar cells in the skateboard he gave Conan alone are a huge technology.

So after he invested, Dr. Agasa was even happier with his research, and he would be given a finished product after each research was completed.

So he now has a lot of Professor Agasa's things in his hands.

OK then, if there is nothing else I will go back first.

Hearing everyone's agreement, Higashino Yuu from the box-shaped world simply waved his hand with a smile and prepared to go back. After all, there was a gift game tomorrow, although that gift game had little to do with him.

But he couldn't just watch his companion get hurt.

"Wait, don't leave yet, I have something to ask you."

Looking at his originally silent demon world, Higashino Yu suddenly said.

Higashino Yuu from the small garden world was a little surprised when he heard this.

Not only him, but even everyone who was chatting was very surprised.

"What is it? I now have a gift similar to a perpetual motion machine. Can I go to my world and find the Infinite Dragon God to further develop this spiritual power?"

"I'll go! That's a good idea!"

Upon hearing this, Higashino Yuu's eyes in the small garden world suddenly lit up.

Because of the existence of the Savior's spirit, although he saw the third law and the merits of the world of death at that time, the fusion of spirits produced a gift similar to a perpetual motion machine.

But it doesn’t mean that this gift is not strong. On the contrary, the power of this spirit is also enormous.

After all, this is one of the gifts possessed by the protagonist of the original work, Izayoi Sakamaki, and because of the changes in the world, there may be a possible historical transition period. Not only Izayoi Sakamaki's gift, but even Maxwell will get a sip of soup because of this historical transition period.

"So are you ready to attack the Infinite Dragon God of your world?"

"No! I just have an idea if you need it, but I'm going to ask you to confirm it. After all, our summer vacation is about to start, and then the Infinite Dragon God will appear for the first time."

Dong Yeyou from the demon world said calmly.

Infinite Dragon God Orpheus. The Ouroboros symbolizes infinite reincarnation and possesses infinite power. Of course, this is only in the demon world. In fact, the Ouroboros also has great significance in various religions.

Plato described the Ouroboros as a cosmic ancestor in a state of self-devouring, immortal, and possessing a perfect biological structure:

0 .... 0

“This creature has no eyes, because there is nothing outside it to see;

It also has no ears, because there is nothing in the periphery to listen to;

There is no breath outside, so it does not need to breathe;

It has no organs of any kind, and because there is nothing around it to be taken in or excreted by it, there is no need for any digestion.

When it is born, its excrement is arranged to become its food. Its behavior and the influence of its behavior come from these and are received from there.

The Creator conceived this creature to be self-sufficient, more perfect than other creatures that lack everything.

Furthermore, it does not need to take any defensive measures against any object, and the Creator does not see the need to give any sacrifice to its hands.

It has no feet or legs; its entire body is a means of movement.

Although it possesses supreme mind and wisdom, its concept of movement is rather vague, because it only exists in the same position, so its movement trajectory is like a sphere;

But due to its own limitations, it can only rotate in a circle. "

Therefore, if they obtain the power of Ouroboros and then use this power to come to the small garden world, the improvement they will receive will be terrifying.

Maybe he could use this power to directly upgrade his perpetual motion-like gift to the same level as his savior, level three.

587. Return to the Underworld and Meet Gurefia

After all, that is the legendary Ouroboros. Not to mention its demand in mathematical relationships, physics, and alchemy, they can even be found in the myths and legends of every region.

For example, in Norse mythology, the giant snake Jörmungandr, one of the three children of the evil god Loki, is a giant creature that can surround the entire world with its body and bite its own tail at the other end with its mouth.

In Christianity, the Ouroboros is considered to be the border and limit of the entire material world and the representative of "self-destruction" in pantheism and mysticism.

The concept of ouroboros is also popular in Indian folklore. In Indian mythology, the snake god Shesha surrounds the tortoise god Kurima and supports eight elephants that are responsible for carrying the entire world.

In many West African religions, the snake is a sacred animal. The image of the demigod Edu "040" Feidu is a large snake biting its own tail. The Ouroboros symbol also appears in the sacred images of the African Wind and Dahomey peoples, becoming the concrete image of the Rainbow Serpent in local beliefs.

In Central America (such as Mexico), the Quetzalcoatl worshipped by the local Aztec people was also depicted as an Ouroboros.

In addition, during the period when fascism was prevalent in Europe, the Italian Regency of Carnaro, which briefly appeared on the historical stage, had an Ouroboros on its flag.

And even in the small garden, there is a demon community called Ouroboros.

All these things are enough to show how serious the consequences would be if Higashino Yuru obtained the power of Ouroboros.

"It would be even better if you could sign a contract with the Infinite Dragon God. In that case, the power we gain will be the strongest."

Higashino Yuu from the small garden world thought for a moment and nodded.

Just like the contract signed with the Venus Goddess in the Type-Moon world benefited everyone in the end, if Higashino Yuu in the Demon World can sign a contract with the Infinite Dragon God, he can get a similar effect.

"Indeed, if you sign a contract with the Infinite Dragon God, then I might be able to kill two more serpents."

Higashino Yuya from the God Slayer world nodded.

As mentioned above, Ouroboros is a creature that exists in various legends. Even if Higashino Yuushi from the God Slayer world kills it, there is no guarantee that he will obtain its infinite power.

But if Higashino Yuu from the demon world had signed a contract with Orpheus first, then he would have a great chance of gaining unlimited power.

After all, this is different from other worlds. In the demon world, "infinity" refers only to Orpheus.

Moreover, they have already reached this level, and it is very difficult to move up. For example, he has now become a demon god by leveraging the phase of the Church of Science, but it is very difficult to move up by relying on the Church of Science. Even he himself does not have any good ideas, so he has set his sights on the path of the savior.

But since it is difficult in this direction, it is not a problem for him to work hard in other directions to make up for his shortcomings.

Looking at everyone's excited eyes after hearing the words of Higashino Yuu from the Little Garden world and Higashino Yuu from the Toaru Majutsu no Index world, Higashino Yuu from the Devil's world could only nod.

"Okay, since you all say so, I'll go back and prepare now."

Higashino Yu from the demon world nodded and then followed him out of the foggy space.

Demonic world.

While different things are happening in each world, his world is also constantly moving forward.

Now the event in the original work where Azazel and the three parties of Mythology signed the peace jump agreement has passed, and now they are about to go to the underworld to spend a perfect summer vacation in the underworld.

"Huh - is this your Underworld Train? I've heard of it before, but this is the first time I've actually seen it!"

"Haha, yes, not only that, did you know that in the past history, you are also the first human to step into the underworld with a legal identity."

After getting ready, Rias held Higashino Yu's arm and stood on the balcony of the train to the underworld.

In addition to Rias, there are also Akeno, Koneko, Asia, and even Xenova and Sekiryuutei.

"I wonder if I'll see my old friend when I enter the underworld. I have to say it was really fun to fight that white guy last time!"

The Red Dragon Emperor, who had transformed into a motorcycle robot, stood behind everyone and sighed...

He wanted to laugh when he thought about the last time the white guy's host betrayed the Fallen Angel, leading to a fight between the two.

Over the years, the two of them either competed in strength or in host competition, and the final result was always mutual destruction. Only this time was different. This time he directly unsealed and transformed into an alternative artifact, and became a demon, really venting his anger.

The Gremory base in the underworld.

As the train gradually stopped, everyone got off the train.

As if they had known that Rias and the others were coming back, the castle gate opened, and hundreds of maids and waiters stood on both sides.

"Welcome back, Rias-sama, Higashino-sama, and everyone else."

The silver-haired maid Grayfia stood in front of everyone, and next to her was a little boy with the same hair color as Rias.

"Sister-in-law, I told you not to do this. And Miligas, long time no see!" Rias greeted the two of them with a wry smile, and did not forget to introduce Higashino Yu.

"Dongye, this one you have met is my sister-in-law Gurefia, and this one is my brother's child, Miligas."

"Well, hello."

Higashino Yuya waved his hand gently.

"Um, hello. I saw you in my aunt's last ranked game. You are Higashino Yuu, right? Can you teach me how to fight?"

Miligas looked at 0.3 Higashino Yu with shining eyes, and he looked just like a fan seeing his idol.

"I'm sorry, but I saw your battle last time, so I fell in love with your gorgeous, controlled fighting style and your gorgeous lightning attacks."

Gurefia was talking about the last time when Higashino Yu used ancient book magic to teleport all the enemies' locations and then easily defeated Riser.

"Haha, if you want to learn, I can teach you!" Dong Yeyou said with a smile, rubbing his head gently.

Sure enough, the other party's eyes lit up when he heard it.

"really?"

"Of course!"

However, before Higashino Yu could continue speaking, Rias stopped doing it.

"Dongye, you can't do this!"

588. Ravel and Rasel

"That move is just too precious. And it's also too dangerous."

Rias frowned and couldn't help but say.

Not to mention the important role that ancient book magic can play in actual combat, even if the combined attack magic is given to Miligas now, he may not be able to use it. After all, this is a trick specially studied for Yuto Kiba and others, and it is not suitable for everyone.

"Don't worry, tricks are only temporary strength. To be truly strong, you still need a strong heart."

Higashino Yu rubbed Miligas's head, and then directly used the ancient document magic to teach him the ancient document magic.

He remembered that in the original book, this child became one of the six transcendents thirty years later. He was really talented.

"Thank you, Brother Higashino!" Miligas felt the information in his mind and immediately smiled happily. He also became much more friendly towards the appearance of Higashino Yu.

"By the way, Brother Dongye, let me tell you something. The lady from the Phoenix family is waiting for you at home now."

"The young lady from the Phoenix family? Could it be that Ravel?"

As Higashino Yuu finished speaking, Rias, who was hugging Higashino Yuu's arm tightly, froze with a look as if she wanted to say something but hesitated.

"Yeah, I heard that after fighting with you, Brother Dongye, he lost his confidence and became depressed, so his family seemed to hope that you could awaken his fighting spirit."

Miligas nodded.

"I have discussed this matter with Sirzechs, my mother and my father. They said that whether you are willing to help them depends entirely on your own ideas." Gurefia on the side said slowly after hearing this.

Not to mention that Higashino Yuu is a human being, his current strength is not something they can command with just a single word.
