Duels should be played with a smile.

"Time is a very magical thing," Leyou said in a very mysterious tone, uttering the words he had just come up with.

"I'll take what you say as true for now, but according to our research, the changes that have occurred in your time are not necessarily caused by me."

Upon hearing something that might be useful, Zone immediately became interested. As someone determined to save the world and take action, he was interested in any method that might save the world.

"Please speak, I am willing to hear the details."

Seeing that the zone had been temporarily stabilized, Leyou gave Ella a wink, secretly organized the thing he had just made up, and spoke.

"For all existence, the past is unique, the present is unique, but the future is infinitely possible and completely unknown."

"Therefore, only one past and one present can coexist at the same time. Before the future becomes the present and the past, anything can happen in the future."

"You say you come from the future and travel through time to find a way to save the world, which is feasible. However, no matter what you did in the past, under the spacetime correction force, it is not certain that your actions will affect the future in which you exist. If the past has indeed changed, then it will only create another parallel future, rather than changing the future in which you exist."

“You’re lying,” Zone suddenly said.

Through a mask, and a virtual one at that, Zone's gaze was not real and could not penetrate the mask's barrier, but Leyou could definitely feel the sharp gaze coming from the other side.

"Your attempt to save your era through the 'Thirteen Secrets' is essentially the same as our time travel to save our era, but you use a set of arguments to deny my claims."

You are lying.

“No, no, no, completely different.” Le You raised a finger without changing his expression and shook his head. “The plan of the Thirteen Secret Words is fundamentally different from yours.”

"What?" Zone asked instinctively.

Le You's lips curled up slightly. Anyone who knew him would know that he was about to start again.

"The methods you've used are essentially about interfering with the past to influence the future. I suspect you've tried things like erasing key figures from the past to 'fundamentally' solve the problem, right?"

Zone nodded silently. They had indeed tried that, but...

"But your attempts either fail to address the specific individuals involved, or the problems persist even after you've resolved them, am I right?"

Zone nodded again.

Seeing Zone nod, Leyou breathed a slight sigh of relief. He had just guessed based on the plot of the animation, but luckily he had guessed correctly.

Of course, if you guess wrong, there's still an explanation. After all, those fortune tellers on the street, and those who offer horoscope readings, tarot readings, and other miscellaneous services online, basically all follow this pattern.

With a variety of ambiguous or likely correct statements, there's bound to be one that suits you.

“Our Thirteen Secrets are different from yours. We have never tried to change the future, or rather, we have never cared about changing the future, because we knew from the beginning that no matter how we change the future, we cannot affect the future we are in.”

"The purpose of the 'Thirteen Secrets' is not to change anything, but to find them, confirm their existence, and then return to our time. Through the methods we have developed, we can use the meaning represented by their existence to anchor the entire past and the entire history of Duel Monsters."

"In our timeline, the history of Duel Monsters is inseparable from human history. When the history of Duel Monsters is anchored and established, then the history of Duel Monsters can continue, and the history of humankind, which is closely related to it, can naturally continue as well. This is our goal."

Having finally managed to make sense of what she had made up, Leyou habitually stroked the crystal pendant hanging around her neck and breathed a sigh of relief.

Hopefully, I can keep this guy in line, so he won't start a duel at the slightest disagreement.

As the final boss of 5DS, wielding the overpowered deck "Time God," Leyou's acrobatic decks might not guarantee a win.

After all, he doesn't know how to draw cards or create lucky draws.

After Leyou finished speaking, Zone remained silent, lost in thought, seemingly pondering something. It wasn't until quite a while later that he spoke again.

"What you're saying might be correct, but..."

"In order for our era to be saved, I must use a more prudent approach to ensure that no accidents occur."

"We have been waiting, searching, and wandering for far too long, so long that we can no longer wait for the next possibility."

"I must verify this myself."

Chapter Thirty-Five is exactly what we wanted to see.

"stop!"

Before Zone could start playing cards without warning, Leyou shouted to stop him.

"Could you tell us what caused the destruction of your world? Perhaps I can offer some different advice from the perspective of our time?"

Leyou didn't mind resolving this matter through a duel, but he didn't like doing things he wasn't sure he could handle.

With all his tricks up his sleeve, dealing with opponents that require Crab Bro to draw out Shooting Quasar Dragon to defeat them truly tests the synergy between the deck and the opponent's deck.

Dinosaur Girl is arguably the most powerful card in Leyou's current deck, but against someone like her, the self-destruct switch might not be very effective. Judging from his knowledge of [Thirteen Secrets], he probably also knows that Leyou's Dinosaur Girl deck contains a self-destruct switch.

If the self-destruct switch were known in advance, in this era of only 4000LP, it's really not certain that it could be activated.

"It was because of Synchro Summoning... because the unrestricted use of Synchro Summoning caused the perpetual motion particles to run endlessly until it triggered a catastrophe that destroyed the entire world."

Perhaps because he had brought up distant memories, Zone's voice was a little hoarse, but when he finished speaking and looked at Leyou, he only saw a hint of mockery on Leyou's face.

"What do you mean?"

"It doesn't mean anything, I just feel that you guys are very sad," Leyou said, crossing his arms and shaking his head.

"sorrow?"

"Actually, I admired you guys a lot before. Although you have a bit of a heroic view of history, whenever there is a crisis of destruction in human history, there are always countless capable people who stand up to turn the tide and save the building from collapse. I admire such people, and I would admire you too."

"Unfortunately, you've taken the wrong path."

"Did we take the wrong road?" Zone repeated Leyou's words like a broken record.

"Because Synchro Summoning is truly unworthy of destroying the world."

Because the water purifier is a damn link monster (laughs)

"You may not know the specific meaning of the thirteen secrets, but you should be able to discover that there is no Synchro Monster among those thirteen secrets."

"You think you can change the past and make history go according to your ideas, but you don't realize that you are actually stifling the possibilities of humanity. Just because you are afraid that the Synchro Summoning will destroy the world, you stop and do not move forward. Even if you do change the future, it will only lead the world from destruction to another unknown. No one knows whether you can really change the world."

"But we are different. We went back to the past to make Duel Monsters more versatile. We went back to the past to make the future more colorful. That's why we were able to develop even more powerful Xyz Summoning, Pendulum Summoning, and Link Summoning after Synchro Summoning."

"As you can see, Synchro has not destroyed us, nor has the more powerful Summoning spell. What will destroy us is stagnation."

"..."

“If that’s all, it’s not enough to convince me.” Zone suddenly became unmoved, and his virtual projection began to slowly rise.

“Your words have indeed revealed new possibilities for us, but we will not abandon our original plans.”

"Apollia, he's in your hands now."

Zone's virtual image left so suddenly, but hearing the last name he mentioned, Leyou couldn't feel relaxed at all.

Apollia, the Desperate Guardian, uses a deck designed to counter Synchro Summoning Machine King decks. Most of his monsters cannot be Normal Summoned and need to be summoned through the effects of other cards in the deck. However, this also comes with various troublesome effects.

Moreover, the need for scheduling and special summoning is not a problem when the bonds are maxed out.

Just as Leyou was still pondering which deck to use to counter, Apollia appeared.

As soon as he appeared, he waved his hand, and then Leyou, Ella, and himself disappeared from their original places.

The next second, in a strange space, Leyou and Apollia stood facing each other.

Ella stood aside and watched the battle; she could only watch, because in a sacred duel, no external force was allowed to intervene.

"Let's duel. Win or lose, it won't do anything to you. This duel is just to verify some things," Apollia said coldly.

"If possible, I hope you can show us what our future duel will look like, and let us see the reasons why you deny us."

"Let us know whether Synchro Summoning is truly not the cause of our world's destruction."

"This is a duel, but also an exchange, a...exploration."

Just as Apollia finished speaking, the crystal on Leyou's chest suddenly began to shine with a jade-like luster.

You have arrived on a stage never before performed, and you will show us an unpredictable future.

This is exactly what we want to see.

【I see】

So, go ahead and unleash your potential, your brilliance!

This is exactly what we want to see.

A series of ambiguous words followed by a series of prompts.

[Temporarily unlock all cards]

[Applicable to the latest banned card list]

[Master Rules Temporarily Unlocked]

Please begin your performance; we look forward to it.

"..."

"As you wish."

"That's exactly what I wanted."

Apollia on the opposite side had already taken out his Duel Disk and arranged his deck, waiting for Leyou to get ready so that this unusual duel could begin.

"I will soon prove to you that Synchro Summoning is not worthy of destroying the world, and you will also experience what a pie chart deck is."

"Witness a duel between masters from the future!"

The crystal and the Duel Disk are now integrated, and this time, the Duel Disk has undergone some subtle changes.

The projection of the dueling arena appeared between the two, with two additional areas in between the usual five front and five back zones.

"This is...?"

Leyou smiled and shook his head, not answering Apollia's question. He simply set the condition of not using Synchro Monsters, then randomly drew a deck from the system and placed it on the Duel Disk.

Are you ready?

"Duel!"

[Leyou LP: 8000]

[Apollia: 8000]

[Roll Result: Leyou 6 Apollia 1]

"Although I don't know what deck I'll get, in Master Duel, the first-strike advantage is huge."

Leyou drew five cards from his deck, glanced at his hand, took a deep breath, and closed his eyes.
