Duels should be played with a smile.

Seeing Rakuyu fall from the sky, Shizuka felt as if she had seen a savior.

She remembered that Jonouchi had told her before that Leyu was a very powerful duelist, and that duel, which she didn't understand but seemed very powerful, proved that.

"Who are you?!" The robot looked at the person who did not appear in the database with extreme vigilance.

"I am the Destroyer of Destiny! The End of All Things—I'm here to send you on your way. Enough talk, let's duel!"

Not wanting to bother with such a nobody whose name he didn't even want to remember, Leyou immediately unfolded his Duel Disk.

After the system upgrade, the Duel Disk unlocked a customization feature, allowing users to adjust a range of attributes, including but not limited to size, color scheme, shape, durability, attack power, and defense.

You ask why there's attack and defense? If you make the Duel Disk into the shape of a sword, then it has attack power, right? If you make it into the shape of a shield, then it has defense power, right?

Use your imagination!

Now, Leyou's Duel Disk is very cool. Overall, it looks like a smaller version of a broad-bladed lightsaber. The blade is solid and used to place monsters. One side of the lightsaber blade is the spell and trap zone. There is a field spell zone at the tip of the blade. The hilt is the deck and extra deck. As for the graveyard and banishment zone, they are directly set in the hollow inside the blade.

In short, it's simply cool.

At the very least, the robot's first reaction upon seeing the duel disk was to assume a defensive stance—he almost thought he was about to be dueled by a real person.

"Hmph, all flash and no substance!"

Seeing that the cool greatsword was just a duel disk, the robot secretly breathed a sigh of relief and returned to its original posture.

"Since it's a duel, I'm happy to oblige, but we must follow our rules!"

The rules for deck domination are actually quite boring; to put it simply, they're like the skills in Duel Links.

First, before the duel begins, each player must choose a monster from their deck to be the deck leader. The chosen leader has a special ability that can be activated under certain conditions. However, apart from the monsters that appeared in the original work, none of the others are mentioned. In other words, it's possible to just guess.

Secondly, the Deck Leader can be Special Summoned at any time, but if the Deck Leader is destroyed, the game will end in defeat. However, if it is used as material, the Deck Leader's status will be inherited.

Overall, there's nothing particularly special about it.

"Choose your own deck and decide on the deck leader!" the robot said confidently.

"Then there's no need for you to trouble yourselves; I have my own deck."

Don't ask, the answer is the omnipotent system.

"Impossible, you can't bring in decks from outside!"

"I didn't just bring what I wanted, I'm going to add some extra ingredients for you guys~"

"You guys added a deck leader to the normal duel rules, so I'll add something too, makes perfect sense, right? I'll add something called 'Master Duel' to let you experience the future!"

As soon as the words were spoken, the duel was forcibly started by Leyou, and the duel arena under the Master Rules appeared directly between the two of them.

"What...what have you done?!"

"Don't make such a fuss. You can't just allow the magistrates to set fires while preventing me, a commoner, from even lighting a lamp. Actually, I could go even further, like preventing you from setting fires at all. But think about it, I should at least give you a little bit of the game experience."

[Leyou LP: 8000]

【Robot LP:8000】

It did leave them with some gaming experience, because Leyou didn't take the first move and retained the rule of drawing cards first, just to allow the opponent to survive a few more rounds.

Furthermore, Leyou plans to retain the first-strike card-drawing rule in the early stages of future rule changes, and then remove it as the strength of the decks gradually increases.

"My turn, draw a card! Wait, what's your deck leader?"

Since the five giants only exist in the virtual world and have no physical form, they all use the card deck leaders they choose as their own vessels. They probably created this rule so that they could briefly experience the reality of having a physical body.

"My Deck Leader is just a harmless Level 1 monster with 100 ATK and 100 DEF. I'll just tell you its special ability directly: when it's in the deck, it can be Special Summoned directly. And if it's Tributed, it has one chance to transfer the Deck Leader's status. Of course, transferring only changes the status, it doesn't inherit the ability. In other words, the new Deck Leader is just to ensure that I won't lose because of a single Tribute. How about that? Nothing unreasonable, right?"

After hearing Leyou's explanation, the robot thought about it carefully before slowly nodding and acknowledging the deck's dominance.

They actually had a backup plan: if the enemy's deck control was too overpowered, they would resort to dirty tricks.

Of course, the robot didn't know that if they tried to do something underhanded, they would only be happily sent away by Leyou and the yet-to-be-seen Fireproof Dragon.

"Any more questions? If not, let's get started!"

"Hmph, just wait and see. 8000 LP will only prolong your life for a few more rounds. In the face of my deck-controlling abilities, no amount of LP matters! Soon, your body will belong to me!"

"I activate my Deck Mastery ability! For every card discarded, I deal 500 LP damage!"

"I discard 5 cards! Dealing you a total of 2500 LP damage! Support artillery fire!"

After discarding all but one card in his hand, the robot extended several cannons from behind, aiming them at Leyou from a distance.

"Fire! Hahahaha, feel the pain! In this duel, all damage will cause real pain, and it will be reflected back to you!"

Boom—

A series of cannon shots rang out, raising clouds of smoke and dust.

Seeing this, Shizuka, who was watching from the sidelines, was startled: "Mr. Rakuyu... he won't be alright, will he? He absolutely can't hurt himself while saving me!"

“No, he won’t lose.” Ella shook her head slightly.

"He was just playing around."

"play?"

"That's right, look."

As the cannon fire subsided and the smoke cleared, Leyou appeared before them completely unharmed, his hairstyle unchanged.

"That's it?"

"You call this firing a cannon?"

[Leyou LP: 8000 → 5500]

"Hmph, consider yourself lucky. If you hadn't forcibly changed the rules, you would have been dead in the next round!"

"I activate the spell card [Heavenly Treasure Card], replenishing both of our hands to six cards each. Now I have six cards in my hand again, and you're not far from death!"

Five cards of unknown origin and a treasure card that fell from the sky—Leyou didn't know how to comment on this. Is it possible that everyone in this era has a full set of cards?

"On my first turn, I cannot attack. I set a monster face down, and my turn ends."

"Although I don't know what methods you used to forcibly change the rules, increasing your LP to 8000 only lets you live a few more rounds! Soon, your body will belong to me!"

After discarding five cards, the robot ended its turn with five cards remaining, which fully demonstrates how deceptive the "Heavenly Treasure Card" is.

"You said you'd let me live a few more rounds...tsk tsk tsk, I was originally planning to let you live a few more rounds, but it seems you don't cherish this opportunity."

"Since that's the case, don't blame me for being ruthless."

Looking at his hand, Leyou knew that this duel could end at any moment.

"My turn, draw a card!"

"Come forth, my deck master!"

"I Special Summon my Deck Leader from my Deck! The adorable [Lost Dog Machig]!"

Chapter Sixty-Seven: Fire the Cannon!!!! Paying Back the Debt 2/34

When a skilled OCG player sees this adorable little puppy, they'll start checking their hand for any hidden cards; if not, they'll fast-forward to the next round.

Humans like this robot, who rely on changing the rules to gain an advantage in card games, have no idea of ​​the great terror hidden behind this little dog.

"Hahahaha, I thought your deck leader was really powerful, but even its effect is so meaningless."

The effect of Little Chestnut is simple: when it is sent to the graveyard, you can choose to send this card to the bottom of the deck or search for a "Lost Chestnut" and then return this card to the top of the deck.

On its own, it does seem to have very little meaning, but Yu-Gi-Oh! has never been a game that only looks at individual cards.

To be fair, Maruko is really cute. At least when Shizuka saw Maruko, her eyes almost turned into two hearts.

Leyou gave the robot opposite him a meaningful look, eagerly anticipating what expression the robot would make.

"I'll show you the meaning of this incomprehensible effect in no time!"

"The summoning condition is one 1-star monster. I'll set Little Chestnut as an arrow and link summon!"

"Link 1, connect to the chestnut ball!"

In the virtual world, a small data storm suddenly arose, enveloping Little Ma Li and transforming it into a brand new data stream.

A moment later, the equally adorable Connect Kuriboh appeared in the Extra Monster Zone.

"Link Summoning?! What is that?" The robot seemed completely bewildered.

"You don't need to know so much about Yu-Gi-Oh! Anyway, I'll show you what real firing is all about in a bit!"

Although Leyou could have easily crushed the opponent with his dump truck because he was the second to act, the thought of being the one driving the dump truck and getting fired at first made him feel uneasy if he didn't retaliate.

"Because Little Masuki was sent to the graveyard as material, the title of deck leader was inherited by Link Kuriboh. At the same time, Little Masuki's effect was activated, and it will return directly to the bottom of the deck."

"Then comes the forbidden door that opens all taboos!"

"I activate the Spell Card [Monster Gate]!"

"Tribute the Link Kuriboh on the field, and flip the top card of your Deck until a monster that can be Normal Summoned appears. Special Summon that monster. Send all other flipped cards to the Graveyard."

"Let me tell you in advance, the only monster in my entire deck that can be Normal Summoned is Little Marble. In other words..."

"I just destroyed the entire deck!"

The connected Kuriboh, with a small tail, leaped into the air, its body transforming back into a data stream, then into a strange portal. At the same time, Leyou's deck naturally floated up and began to be flipped through one by one.

[Technology-based Halberd Gunner/Explosive Type]

【Dragon's Cleverness - Heavenly Dragon Meteor = DRA】

【Long Yi Qiao - Tian Long Liu Xing = QUA】

【The King of Machines: The Legend of the Machines∞】

The entire deck, including these four Level 12 Machine-Type monsters that cannot be Normal Summoned, was sent to the Graveyard by Monster Gate. Finally, at the very end of the deck, the bottom-ranked Makoto was a monster that could be Normal Summoned.

So, after a series of maneuvers, Little Maris returned to the field and reclaimed his status as the leader of the deck.

With Xiao Ma Li overseeing the battle, how can we possibly lose this round?

"What is Mr. Leyou doing? I heard from my brother that if you don't have any cards in your deck and can't draw any more, you'll lose immediately, right?" Shizuka, who didn't know much about playing cards, asked Ella beside her.

By the way, Isla is quite tall, at least a head taller than Shizuka.

Faced with Shizuka's question, Ella remained unmoved and calmly replied, "As long as we take down our opponents before we draw the cards, that's fine."
