Duels should be played with a smile.

Leyu stood in front of Seto Kaiba, stretched his body, yawned, felt the warm sunshine, and uttered a sentence lightly.

Seto Kaiba was stunned for a moment, not quite able to react.

“Why so serious?” Leyou asked again.

"Why assume we're adversaries from the start? Why don't you consider that we can cooperate?"

"Cooperation? Hmph!" Seahorse turned his head away disdainfully. "There is no possibility of cooperation with anyone who attempts to usurp the Seahorse Group!"

"Tsk tsk tsk, too small!" Leyou waved his hand. "Too narrow-minded!"

"Why do you think we would be interested in your small Haima Group? In our time, Haima Group was just a subsidiary. It was only because its founder made a lot of contributions that Haima Group retained its original name and logo."

"Era? Subsidiary? What do you mean?!"

Upon suddenly hearing about Haima Company, Haima momentarily lost his composure, but quickly regained his composure.

"If you're trying to fool me with this nonsense, you'd better leave now and not waste your time here."

Seto Kaiba is a firm believer in science, and with his knowledge, he naturally knows that time travel is basically only a fantasy.

"Why would I lie to you in such a boring place? You don't have anything worth lying about." Le You said these useless words, but his mind was already racing, trying to come up with a more entertaining story.

"Well then, since you're so eager to know my background, I might as well tell you directly."

Unfolding his duel disk and communicating with the system in his mind, Leyou began his performance, following the script he had prepared.

"We unveiled the veil of the future, only to see annihilation. So we exhausted everything to find a glimmer of hope in the long river of time."

With a melodious and rhythmic tone, he recited the riddle he had just composed. Leyu removed his hand from the Duel Disk, and a stream of emerald light flashed, transforming back into a pendant around his neck. The Duel Disk in his hand became identical to the one in Seto Kaiba's hand, completely unremarkable.

"We come from the present future, and the future past. We travel through countless times and spaces in search of the only hope."

Sunlight shone on the jade crystal on her chest, reflecting a soft glow.

"We are 'eternity'."

"I came to save the world."

Chapter Nineteen: Due in Heaven!

Time seemed to stand still.

Seto Kaiba stood frozen in place, speechless.

Leyou calmly awaited the seahorse's response.

Seto Kaiba was deeply shocked at that moment.

He was a firm believer in science and naturally wouldn't be fooled by the riddle that Leyou had just made up, but the facts he saw with his own eyes told him that those strange changes were not false.

He firmly believes in science and will not be deceived by superstitious things, but from a scientific and technological point of view, time travel is not entirely impossible.

"It's just some projections. This level of projection technology isn't much more advanced than the technology used in the Duel Disk."

The projection technology on the Duel Disks currently sold by Hikvision is already quite realistic, but it hasn't reached the limit of their technology yet.

It is well known that when a company releases a technology product, its actual performance level must be at least 10% higher than the release level.

Inside Kaiba Corporation, the Duel Robots that Seto Kaiba frequently uses for practice are equipped with the latest projection technology and intelligent systems. With this cutting-edge technology and some clever techniques, it is not difficult to achieve the level of performance that Leyu just demonstrated.

Seto Kaiba slightly raised his assessment of the strength of the forces behind Lei Yu, but still only regarded him as a competitor with some strength.

"If you can't come up with something better... what is this?!"

In front of Seto Kaiba, Rayu opened his arms, and the crystal on his chest projected the phantom images of ten cards arranged in a neat row. These ten cards were tilted at the same angle and rotated at the same speed, with the face of some cards constantly changing with each rotation.

Of all the cards on this card, only the third one was one that the seahorse recognized and remembered; the rest were cards he had never seen before.

It's fair to say that it was something we never even imagined.

Because among these cards, apart from the effect monsters with orange borders, the fusion monsters with purple borders, and the spell cards with green borders, the rest were all styles he had never seen before.

Above these ten cards, there are three more cards, all with blue borders, no defense stats, and unique monster illustrations with two arrows.

"This is proof that we come from the future, and it is also the purpose of our coming here."

Leyou was very satisfied with what he had come up with on the spur of the moment. The things he showed were ingrained in the DNA of most card players.

Even if some people haven't experienced all of them for various reasons, there are at least a few cards that are well-known among card players.

"In our time, Duel Monsters has already developed to near perfection, and the closer it gets to perfection, the closer it gets to the end of the road."

Leyou's tone carried a hint of vicissitude, as if he were depicting an epic painting.

"The ultimate prosperity is decline and destruction. The combined power of countless cards with great strength is enough to destroy the entire world, from the past to the future, erasing the history of Duel Monsters."

"Our era is the end of everything. In order to continue our history and to prevent the traces of humanity and Duel Monsters from being buried in the river of time, all of humanity gathered all its strength and finally found a way to continue the future at the last moment."

"But in the end, we failed because there was no hope for the future, and the only way to make the future continue was in the past."

"To this end, we spent a lot of resources to calculate the key nodes that would allow the future to continue, and recorded them. We then sent ourselves, carrying the last spark of hope, back to the present, to the era when Duel Monsters were just born, the starting point of it all."

"What I'm showing you are thirteen nodes that can anchor the world. Only by collecting them all and inscribing them in the annals of Duel Monsters can Duel Monsters and humans continue to survive."

“We call it the ‘Thirteen Secrets’.”

As Leyu finished speaking, the thirteen cards simultaneously flashed with a mysterious light, which, in Seto Kaiba's eyes, was a dazzling light that was almost blinding.

Seto Kaiba was unable to speak.

He had no way of knowing whether Leyou's words were true or false.

His intuition told him that those cards truly possessed immense power, because the only one he recognized was Exodia, the one that had left him with unforgettable memories.

Left hand, right hand, left foot, right foot, plus the last part of the torso, that was Exodia, who had once crushed him.

What kind of powerful card could be ranked alongside Exodia?

He was so shocked by the story Leyou told that he forgot his original purpose.

Seeing that he had almost completely fooled Seto Kaiba, Leyou thought for a moment, then revealed a mysterious smile, preparing to add the final push.

"Kaiba Seto!"

Have you ever seen the future?

While Seto Kaiba was still in a daze, Leyou had already reopened the Duel Disk, and the crystal carrying the system was reintegrated into the Duel Disk. The cards that had been projected earlier also floated above Leyou's Duel Disk as he moved.

"I have great respect for the people who brought about the creation of the card monsters, because that's how Duel Monsters developed step by step."

"Seto Kaiba, if I let you witness a duel from the future, would you still want to stay in the past?"

The thirteen cards shone brightly, and a yearning for power appeared in Seto Kaiba's eyes.

He controls the powerful Blue-Eyes White Dragon because he loves its immense power.

He wielded the Titan of Obelisk, hoping to use its invincible power to crush all enemies.

Therefore, he also had some anticipation for this unknown force before him, the authenticity of which was uncertain, but which held some possibility.

"Humans must eventually move towards the future, Seto Kaiba. Do you know that from the moment we came into this world, the duels have been accelerating!"

Regarding the antics in the previous chapter

@@When I first thought about doing something like this, I already guessed that there would be a lot of controversy.

Let me briefly explain why I made this choice.

It's impossible to convince everyone, because everyone has their own ideas.

----

The Creation Dragon, the Victory Dragon, and Old Ai – these three should need no explanation.

The Eight Crows represent the entire early stage, including the Chaos family and those...

The Dragon Conqueror's Spellbook ushered in a super-mainstream era; these two should either not be written at all or be written together. Then there's the argument that only Divine Judgment is needed, but Dragon Conqueror is a system, and so is the Spellbook system, so let's consider a parallel.

EMem was the core of the entire Pendulum R4 era.

Leaving aside the Twelve Beasts, adding Victory Dragon makes it the only deck with no restrictions.

Firewall Dragon represented the entire period from the early days of the game until Firewall Dragon was banned, including SPY and similar titles. It was also a forbidden card for the main character. Then, with the introduction of Firewall Dragon, the title was removed.

Red Daddy is the most famous and popular single card in the later stages of OCG, and it is also the representative of Konami's ultimate butt-printing cards, so its status is definitely high enough.

Then the remaining three are unique in status, with the silver, gold, water, machine, and python placed together.

---

That's pretty much it. This is just my personal opinion, and I've written down the reasons. I know it won't convince everyone, but at least it shows I didn't just write something randomly.

Many people have mentioned True Dragon Sword Emperor, Demon Bell Cave, and Demon Science, but in my personal ranking, these are somewhat lacking compared to my selections, or perhaps I've overlooked them. After all, I'm not an OCG encyclopedia.
