The protagonist of the Yu-Gi-Oh! world might be the same person.

"Summoning [Transforming Warrior - Microscope], in attack stance, clang clang!"

As Ryuya slammed the card onto the Duel Disk, a large black microscope was projected, and with a few clicks, it transformed into a robot.

"It's a Transformers fighter..." Yusei's face showed a slight look of surprise.

"Does Yusei recognize this deck?" Ryua asked curiously.

"Yes, just like you said, it is indeed a very powerful deck."

"Right, right! Longke always says I'm weak..."

"Here we go again. Longya gets easily carried away when people praise her." Long Ke sighed, rubbing her forehead, thinking that Youxing was just trying to appease Longya.

It wasn't that Yusei was trying to coax the child, but rather that the Transformers series truly possessed considerable strength.

In the early days, decks that could achieve Synchro Summoning and summon Shooting Star were only known for cards like the Destroyer and the Shapeshifter. It's true that this deck was strong, but currently, there aren't enough conditions to unleash its true power.

Ryuya ignored his younger sister's complaints and continued with his own actions: "The monster effect of the Shapeshifter changes depending on the card's position. When Microscope is in Attack Position, it can Special Summon a Level 4 Shapeshifter monster from its hand once per turn."

"Come on, [Transformer Camera]!"

The next moment, a light effect flashed, and a large camera appeared along with the light, transforming into a robot in a few quick clicks.

[Dragon's hand cards: 6 → 4]

"Then, the level four [Transformer Camera] adjusts the star rating of the level three [Transformer Microscope]!"

"To protect world peace, let us combine courage and strength!"

"Synchronization Summon! Messenger of Love and Justice, [Power Tool Dragon]!!"

As Ryja finished his childlike (and low-EQ: pathetic) summoning lines, Synchro Light blazed brightly, and a mechanical dragon burst through the light and landed in front of him. It was covered in yellow armor, had a shovel attached to its tail, a flathead screwdriver mounted on its left arm, and used a digging bucket as a claw on its right arm.

[Power Tool Dragon: Attack Power 2300]

Looking at the steel dragon before him, Yusei murmured softly, "A power tool, huh..."

He finally understood why the Red Dragon had brought him here yesterday. It was because the effect of the monster "Ultramania Zorkin" was to Special Summon a "Power Tool" Synchro Monster or a Level 7 or 8 Dragon Synchro Monster directly from the Extra Deck. So, the Red Dragon considered Dragonia and Zorkin as his allies?

Moreover, Yusei's Stardust Dragon and Jack's Crimson Dragon just happen to meet the condition of being a 7-8 star Dragon Synchro Monster. In other words, Jack is also the one chosen by the Crimson Dragon. He didn't actually want Yusei and Jack, who should have become his comrades, to fight each other. That's why he was in such a hurry to take Yusei away last night.

"Yusei, this is my ace monster. Isn't it cool?"

"..." Ryuya's words interrupted Yusei's thoughts, and he didn't have time to reply for a moment. IV

"The duels with Ryuya must be annoying, right?"

"Long Ke, don't interrupt. This is a very important moment!"

Watching the twins bicker, Yusei's lips curled up almost imperceptibly. Those two kids really get along well...

"【Power Tool Dragon】can select three Equip Spells from its deck and show them to the opponent. The opponent randomly selects one of them, and the remaining cards are returned to the deck."

As soon as Ryuya finished speaking, the Duel Disk automatically and rapidly shuffled, and three cards bounced up.

"I chose these three..." (Five)

He then revealed the three cards to Yusei: [Two-Piece Tool Set D&C], [Transformer Repair Device], and [Destruction Card Draw].

After shuffling the cards, Yusei casually pointed to one and said, "Then let's go with the card on the left."

Ryuya immediately became excited: "Yosh! Yusei, the card you chose is [Two-Piece Tool D&C]. I'll add this card to my hand, and return the remaining two cards to the deck."

Swish swish swish swish...!

After the two cards were returned to the deck, the Duel Disk automatically shuffled the deck again.

"And I activate the Equip Spell 【Two-Piece Tool D&C】. This card can only be equipped to 【Power Tool Dragon】 or a Level 4 or higher 【Transformer】 monster. During your turn, the equipped monster gains 1000 ATK, and the effects of any opponent's monster attacked by the equipped monster are negated."

As soon as he finished speaking, two beams of light appeared on the arms of the power tool dragon. The screwdriver on the left arm quickly transformed into a drill bit, while the right arm turned into a chainsaw.

[Power Tool Dragon: Attack Power 2300 → 3300]

Incidentally, Equip Spells have two effects during the opponent's turn: one is to prevent the opponent from attacking monsters other than the equipped monster, and the other is to destroy the opponent's monster at the end of a battle with the opponent's monster.

While Yusei was pondering, Ryua, realizing there was nothing left to do, excitedly announced, "My turn is over."

[Power Tool Dragon: Attack Power 3300 → 2300]

Chapter Thirteen: The Final Intersection, Another Battle

When Ryūya announced the end of his turn, Yusei also noticed many problems.

Despite having higher defense, the Power Tool Dragon is summoned in attack position when it goes first. Moreover, this monster has the effect of being destroyed by an Equip Card, but since there is only one Equip Card, its effect is not significant.

There are obviously problems with the deck's construction, especially when Power Tool Dragon activates its effect to select an Equip Card. In fact, you could choose three cards of the same name. Some important Equip Spells could be fully upgraded to three to ensure that you get the cards you want. For example, "Transformer - Repair Device" is a must-have card. As the revival point of the Transformer archetype, you can use this card to revive the Microscope and then perform a second Synchro Summon.

In conclusion, there are quite a few problems, but they can all be corrected. I'll spend more time teaching Longya after the game is over...

"My turn, draw a card!"

[Yusei Fudo's hand cards: 5 → 6]

Yusei glanced at his hand and, without hesitation, placed two cards onto the Duel Disk in turn: "I summon [Scrap Changer] from my hand and Special Summon [Mirror Ladybug]."

Two beams of light flashed across the field, and two monsters were projected in the blink of an eye.

"Why summon two monsters at once?"

In response to Ryua's question, Yusei explained softly, "The effect of [Mirror Ladybug] is that when you control more than one monster and have no monsters in your Graveyard, you can Special Summon it from your hand, and its Level becomes the sum of the Levels of all your monsters other than this card."

"The [Scrap Modifier] is level three, therefore the [Mirror Ladybug] becomes level three."

Then Yusei raised his voice and shouted, "I'm using a level 3 Ladybug to upgrade a level 3 Scrap Changer!"

"O holy lance that illuminates the starry sky, liberate souls and awaken the world!"

"Synchronization Summon! Appear, [Stardust Assault Warrior]!"

As soon as he finished speaking, a burst of synchronized light appeared, and a Stardust Warrior with two screwdrivers mounted on his arms emerged from the light.

Stardust Assault Warrior: Attack Power 2100

"Uh... so cool..." Longya was startled at first when he saw the monster in front of him, but then he breathed a sigh of relief after seeing its attack power stats: "But, the attack power of the [Stardust Assault Warrior] is not as high as that of the [Power Tool Dragon], you know?"

Long Ke reminded him, "Long Ya, you can't judge things by appearances."

"I got it!"

Just then, Yusei continued, "At this moment, the monster effect of [Stardust Strike Warrior] activates, and when it is successfully Synchro Summoned, a [Scrap] monster is Special Summoned from the Graveyard."

After the monster revives, it continues: "And if [Scrap Changer] is Summoned or Special Summoned, the Level of a [Scrap] monster on the field increases or decreases by one star, and the Level of [Scrap Changer] decreases to two stars."

"Next, the level six [Stardust Assault Warrior] adjusted the star rating of the level two [Scrap Modifier]!"

"May our gathered prayers become the shining stars of new life, and the path that shines brightly!"

"Synchronization Summon! Soar, Stardust Dragon!!"

The next moment, dazzling light shot into the sky, and a dragon shadow solidified in the light, flying swiftly with shimmering starlight.

'roar--!!'

Stardust Dragon: Attack Power 2500

Looking at the Stardust Dragon before him, even the dragon instinctively exclaimed in amazement, "What a beautiful dragon..."

"Wow~! I'm fired up! Synchro Summoning Double Strike! Hiss, hiss hiss hiss hiss hiss hiss hiss hiss hiss hiss!"

Just as Ryua was getting excited, Yusei gave the order: "Let's fight!"

"what......"

At the same time, Yusei suddenly grabbed a card from his hand and threw it out: "At this moment, I activate a quick-attack spell from my hand, [Final Cross]!"

"During your turn when a Synchro Monster is sent to your Graveyard, one Synchro Monster you control can attack twice this turn. If that monster's original card name contains any of the following: Warrior, Synchro, or Stardust, it can absorb the ATK of one Synchro Monster in your Graveyard."

Stardust Dragon: Attack power 2500 → 4600

"Attack power 4600?!" Long Ya was so shocked by this that he took a step back.

"Go! [Stardust Dragon], attack [Power Tool Dragon]! Meteor Sonic Strike!"

Immediately, the Stardust Dragon opened its massive maw, and the gathered starlight burst forth, hurtling towards the mechanical dragon.

boom--! ! !

"Whoa whoa whoa-!"

[Longya: LP4000→1700]

As the light faded, the mechanical dragon reappeared before Yusei's eyes, only now the drills and chainsaws on its arms were gone, and it had returned to its original form.

Ryuya said smugly, "Hehe! You're too naive, Yusei! [Power Tool Dragon] can be destroyed instead of destroyed by the Equip Card of this card, and [Two-Piece Tool D&C] destroys the opponent's monster directly after damage calculation between the equipped monster and the opponent's monster!"

"......" × 2

However, after waiting for a while, Ryuya still hadn't seen the monster destroyed: "Huh? Why wasn't the [Stardust Dragon] destroyed?"

Looking at her older brother's innocent yet foolish expression, Long Ke couldn't help but facepalm: "Long Ya, that idiot..."

Yusei then slowly explained, "Although the effect of [Two-Piece Tool D&C] is indeed quite good, if the Equip Card is sent to the Graveyard, it cannot activate its effect unless there is another Equip Card that can replace this card and send it to the Graveyard, or you can find a way to prevent [Power Tool Dragon] from being destroyed by battle."

Is...is that so...?

Long Ya frowned, looking like he understood but not quite, clearly his little brain hadn't quite grasped it yet.

Simply put, the effect can be activated as long as both [Power Tool Dragon] and [Two-Piece Tool D&C] remain on the field. Given the characteristics of this deck, which consists of [Transformer] and [Power Tool Dragon], it would be best to add a [Misty Body] or [Laputinus's Super Magic Sword] to directly prevent battle destruction, thus avoiding the waste of equipment cards.

"The battle continues. According to the effect of [Final Intersection], [Stardust Dragon] can launch a second attack!"

"How could this happen...!"

"[Stardust Dragon] attacks [Power Tool Dragon] again, Meteor Sonic Strike!!"

Under Yu Xing's command, Stardust Dragon opened its maw once more, unleashing a torrent of starlight that instantly engulfed the mechanical dragon, reducing it to dust.

boom--! ! !

"Ughh ...

[Longya: LP1700→0]

Chapter Fourteen: The Witch Appears

"Waaaah... Waaah..."

"Ahhh~, I burst into tears right away."

"I'm not crying!"

In front of her sister, Longya wiped away her tears and held back from crying any longer.

At this moment, Yusei slowly walked up to the twins, looked down at Ryua, and said, "You conveyed your heartfelt enjoyment of the duel to me, but are you satisfied with just summoning [Power Tool Dragon]? Apart from some issues with the details of the duel, you also underestimated your opponent."

Ryuya retorted, sticking out his neck, "No, I didn't underestimate Yusei!"

"But you don't have a face card, do you?"

"Ah..." Ryuya finally realized what Yusei meant.

"To underestimate your opponent is to not consider what tactics they might use. Self-centered duels are not advisable (unless you're just putting on a show). You still have a lot to learn if you want to become king."

The thoughtful Long Ke patted Long Ya on the shoulder: "Come on, cheer up!"

Soon, Ryuya cheered up, "Yusei, can you teach me how to duel? I want to become as strong as Yusei!"

Upon hearing this, Yusei's lips curled up slightly: "Sure, but if I hide in your house, my status as a resident of the satellite district might cause you trouble. Is that alright?"

Long Ke smiled sweetly, her hands behind her back, "It's alright, it's just for a few days, there won't be any big problems, feel free to stay."

"Alright, then I'll bother you for a few more days."

"Great!"

Upon hearing that her sister and Yusei had both agreed, Ryuya jumped up excitedly.

For the next few days, Yusei stayed at the twins' house, carefully correcting the problems in Ryuya's duels and teaching him some techniques for using the Shapeshifter deck.

Later, after hearing Ryūya say that he wanted to participate in the Lucky Cup in place of his physically weak sister, Yusei played a few more games of cards with him.

Good morning, Longya!

"Oh, Heavenly Soldier, you're up early!"
