Want to play cards? I'll use my King's Deck!

indeed.

Yu Xi's experience with it was different from that of ordinary 3D images.

While ordinary 3D images can be tactile, they are generally still rather abstract. However, the notebook at this moment is heavy and substantial, no different from a real book, essentially equivalent to the tactile sensation of a materialized elf.

To achieve this, the required level of stereoscopic imaging technology is quite high.

You Xi said nothing more, but with a mix of nervousness and excitement, slowly opened the book.

The seahorse, Cangren, fell silent, and the only sounds in the room were the fish swimming in the tank and the turning of pages in a book.

Most of the entries in the notebook are diary-like, recording what happened on a certain day, month, and year. For example, meeting someone, the progress of the Duel Disk research, strange rumors in the town where he stayed that day, and the battle with the Dark Duelist. And just as Kaiba Aoto said, his existence is mentioned more or less in the latter half of the book.

Looking at these words, and combining them with the history he learned from the internet, a picture vaguely appeared before You Xi's eyes.

It's as if we can already see how the only blood relative who suddenly disappeared without a trace lived in this world a hundred years ago, what kind of adventures he went through, and how he finally achieved a world-renowned feat.

You Xi couldn't help but smile knowingly. He was very satisfied and happy to know that Brother Lai was doing very well.

However, this also caused him new worries and doubts.

Given his previous success and brilliance, why did he disappear again?

The answer may lie in this book.

Thinking of this, You Xi couldn't wait to flip to the next page. When he got to the last page, he did see something unusual yet strangely familiar.

The writing on the last page of the book was not in the language of this world, but in Chinese from Youxi's original world.

—And these words are the “letter” I left for myself.

[Yu Xi:]

My foolish and dear brother, I don't know if you'll ever see this, but by the time you do, I'll probably be no longer in this world.

Ah, don't be sad. This doesn't mean I'm really dead. It's just that I don't know if I can come back safely, or even how. I might spend the rest of my life in that place.

Don't bother looking for me. I won't tell you or anyone else where I went. Just being able to live happily in this world is enough for you; that certainly won't be a problem.

After all, this world values ​​duels above all else, which is completely different from our damn world.

You loved the Yu-Gi-Oh! anime so much when you were little, and you would pester me to play cards all the time. Later, you spent many years in the OCG environment, so you must be thriving in this world.

So I'm not worried about how you live in this world. If you do encounter difficulties that you can't overcome on your own, I've left some information for my descendants. You're free to seek their help.

However, you can only know a person's face, not their heart. Whether the seahorse family is trustworthy and reliable is something you should calmly judge. Don't let them sell you out and then help them count the money.

Of course, if there was a girl you liked in the seahorse family at that time, you didn't need to worry at all, as your blood relation was practically nonexistent. Even though being together wouldn't cause any problems, it would probably be more reliable if the seahorse family could tie themselves to you in this way (laughs).

Well, it all depends on your own wishes.

Okay, that's all I wanted to say. There are still some things I'd like to explain about this world, but you can explore those for yourself once you've arrived. That's what makes it more fun, isn't it?

Oh right, I left you one last gift, I hope you like it.

That's all for now. Welcome to this wonderful world, Yuki.

—A man from the spring.

elder brother……

"Can you understand what's written in the last part?"

Seeing that Youxi's gaze was fixed on the last part of the manuscript for a long time without looking away, and that his expression changed several times, Kaiba Cangren immediately understood what was going on.

"Yes, this is a message from time left for me."

Yu Xi nodded, not telling Kaiba Soto what was written in the letter, but instead closing the book and returning it to him, saying, "Thank you for showing me this journal, Mr. Kaiba. Brother... did anything unusual happen to Mr. Lai Ren before he disappeared? Did he leave me anything else?"

"Everything before the disappearance was quite ordinary, nothing special. If it had been, we and the D Alliance would have discovered it long ago."

The Seahorse Man shook his head and briefly recounted to You Xi everything that had happened before and after the Seahorse Man disappeared a hundred years ago.

Yu Xi had already learned about the details and testimonies through a more in-depth online investigation. Countless dueling detectives had tried to solve this kind of unsolved mystery, but it remained an unsolved case in the end.

Now, hearing Haima Cangren recount the story from the perspective of the person involved only makes the details clearer, but it doesn't offer much help in finding the answer.

If it were useful, it wouldn't have waited until today.

You Xi had already read the letter left by the Seahorse Man before his disappearance. The letter only explained the future development direction of the Seahorse Company and who would lead it. It made no mention of his own whereabouts or the letter he left behind.

Even the spirits residing in the remaining decks had a piece of their memory erased, and it's unknown how their original owner disappeared.

...Well, how should I put it, this was really brilliant.

You really don't want me to find you, bro?

The more the sea goats did this, the more worried Yu-Hsi became.

The fact that the sea brethren did this clearly meant one thing: the place he was going to was so dangerous that he didn't want any possibility of finding his way back.

That's really... incredibly arrogant.

"Finally, our ancestor did leave you a gift."

This time, Kaiba Sojin didn't use any 3D images. Instead, he got up, walked to a wall, pressed his palm down, and the wall split open. His eye and voiceprints passed through, and a safe appeared in front of the two of them.

The safe was opened, and a golden box with the Eye of Horus engraved on its surface was placed on the table.

This is... the gift that Brother Lai Ren left for me?

Looking at the box that felt so familiar, Youxi couldn't help but feel a strong premonition.

"This box has been kept by our Seahorse family for over a hundred years, and no one has ever been able to open it. According to our ancestor, no one but a specific person can damage or open this box."

Kaiba Soujin, who had sat back down in the sofa chair, said to the boy opposite him, "Yuki, since the person that Ancestor 1 was waiting for is you, you should be able to open it, right?"

"……Let me try."

Swallowing hard, suppressing the rising tension in her heart, You Xi's slightly trembling fingers slowly reached towards the golden box.

Sensing contact, the Eye of Horus on the box lit up slightly, emitting a beam of light.

The light swept over You Xi's entire body, seemingly confirming something, and then—

A click sounded.

The lid of the box, which was originally sealed tightly, popped up slightly, revealing a narrow crack.

Youxi removed the lid of the box, revealing the items that had been treasured for a hundred years.

Was it as expected? The contents inside were exactly what You Xi had anticipated.

It was a pile of golden parts, and the Eye of Horus, identical to that on the box, was printed on one of the parts.

Chapter 243 Millennium Puzzle

"Eh—you only said this much after meeting with President Kaiba, and this is all you got?"

night.

The "Magic Chef Inn" where Kiyosumi Academy students stayed.

After the meal, Hoshino Mai and Izayoi Yuki, who had returned to Yuki's room, were both surprised to see the golden box in Yuki's hand, who had come back from Kaiba Corporation.

They had already heard Yu Xi talk about the seahorse people at the dinner table, but this box, which looked just like Yu Xi's "Sealed Golden Chest," was something they had never seen before.

"Yes, that's it."

You Xi nodded, opened the box, revealing hundreds of parts inside.

He trusted both girls completely and didn't need to hide anything from them.

"This is the last gift my brother, the seahorse, left me."

"Is the seahorse your brother, Youxi?"

Compared to hearing about Izayoi Yuki for the first time, Hoshino Mai didn't seem so surprised.

Judging from Yu Xi's attentive attitude towards the Haima people, it was already clear that their relationship was extraordinary; now it's just that it's been confirmed.

"Well, although there's a big age gap between the two brothers, nothing is impossible in the world of duels, so we don't need to worry about such trivial matters. Compared to that..."

With her short hair fluttering slightly, Xingye Wu pointed at the parts in the box, her face filled with undisguised curiosity.

"Xiao Xi, why did your brother leave you this kind of thing? He couldn't have been worried that you wouldn't have money, could he?"

After taking the parts out of the box and examining them briefly, Xing Yewu could tell that they were genuine gold, and of astonishing purity. Not only the parts, but even the box was made of pure gold.

In the market, this amount of gold would be enough to make someone a fortune.

But now, Yu Xi certainly doesn't lack money.

Even if he didn't win the Star Cup, his outstanding performance at the Star Cup would still have plenty of people eager to give him money. Haima Corporation is a prime example.

Since he is Youxi's brother, he must know Youxi's abilities, so he would never give such a vulgar gift, right?

As expected, You Xi shook his head.

"Of course not, this thing is not just gold, it's actually a set of building blocks."

"Building blocks? Those educational toys for little kids?"

Izayoi Yuki frowned slightly; she couldn't understand the meaning of this.

"Not only that, the assembled blocks will be a very special prop."

Seeing the question in Izayoi Yuki's mind, Yuki took out a pen and drew a simple inverted triangle in her notebook. At the center of the triangle was the Eye of Horus.

"Xue, Wu, have you ever heard of the Millennium Artifact?"

Before the girls could answer, Yu Xi continued, "These are top-tier alchemical artifacts made using ancient secret alchemy techniques. There are seven in total. Each one possesses a very special power. For example, the Millennium Eye allows the person who obtains this Millennium Artifact to read the thoughts of their opponents, while the Millennium Jewelry allows one to see the future."

Xingyewu blinked: "They all sound amazing."

"It's more than amazing."

Izayoi Yukido said, "If the power of the Millennium Eye can be used well, needless to say, it will be invincible in areas other than duels, and even in duels, it will be unstoppable. The advantage of a one-sided information gap is too great."

In card duels, the most important aspect is card guessing. Knowing your opponent's deck composition and all their tactical plans is a significant advantage.

Unless there's a huge gap in card decks and raw skill between the two sides, so much so that even if the opponent plays with their cards face up, they still can't win. Otherwise, it's almost impossible to lose a duel if you can read minds. The throne of Duel King is within your grasp.

As for the millennium jewelry, that's even more outrageous than the millennium eye.

"Hmm, it feels like a great treasure that's just as good as the Sinful Treasure."
