Duels should be played with a smile.

"The summoning condition is 2 Dragon-type monsters!"

"I've set up arrows for Blackie and Blueie!"

"O sacred ancient relic, etched with mysterious markings! Under the golden sun's rays, and through the test of time, transform into a star high in the sky!"

"Link 2! [Celestial Holy Seal]!"

[Light·Link 2·Dragon·Attack Power 0·Arrow↙↘]

Although the momentum is quite impressive, Leyou currently only has this one monster on the field.

This can be considered a classic first-move strategy in Dragon Maid's game.

Of course, once you see the powerful characteristics of the Celestial Sphere—link 2, dragon race, 0 attack, and the left and right arrows—most people will understand just how strong this sphere really is.

"I have nothing more to do. I'll cover a backcourt card and end the turn."

With two cards left in hand, and some of them of unclear significance, without strong back row support or the Saintess's backup food, the Dragon Maids will need enough turns to show their strength on their own.

"Being able to use Link Summoning, you're quite capable!"

The professor, maintaining his composure, drew a card from the duel disk on his chest, a hint of appreciation in his eyes.

"From what I can tell, you don't seem like a bad person. You're probably just someone who got lost here due to the time-space turbulence."

"However, in order to further confirm your origins and ensure the safety of the academy, as your teacher, I must properly test you with my duel!"

Professor Chronos, whose demeanor had suddenly changed, even lost his verbal tic. Seeing how serious he looked, Leyou could only smile and nod.

At times like this, all we can do is smile, right?

However, I still want to complain: what exactly can you find out through a duel?

From Professor Chronos's words, we can infer that it is not uncommon for people like Leyou to get lost here. However, the reason why there are so many spacetime turbulence events that people have become accustomed to them is another question worth considering.

In short, as a newcomer to Leyou, I felt that there were still many things I needed to figure out.

Without figuring out these most basic pieces of information, it will probably be very difficult to regain the "rationality" I've lost.

"My turn, I want to..."

"Wait! I have an effect to activate before your preparation phase is over!"

This is where Xiao Lan's role comes into play.

"The Graveyard Trap Card [Half-Dragon Maid's Tidying Up], once per turn, banish this card from your Graveyard, Special Summon 1 [Half-Dragon Maid] monster from your hand or Graveyard, and return the Special Summoned monster to its owner's hand during the End Phase of this turn."

"I will specially recruit Xiao Hei to guard the watch."

After being carefully dressed up, the dormitory dragon girl reappeared, her face showing a calm and composed demeanor, second only to the housekeeper dragon girl in status.

"Xiao Hei effect, retrieve and organize again."

Turning her back, she took out a still-warm card from her chest and handed it to Leyou. The dragon girl in the dormitory had a hint in her eyes.

"Hiss... Take it easy, take it easy."

Returning the same look, Leyou dodged the sudden attack from the dormitory's dragon girl.

It's still Professor Chronos's turn, convergence point.

"You retrieved another Special Summon card... I think I understand your deck now!"

"But you, going first, only have a monster with 0 attack on the field. It seems like you won't survive to the next turn against my Ancient Gear deck!"

Professor Chronos, caught up in his professional habit, wanted to offer a few more pointers, reminding Leyou to try to create more large monsters and cause some disruption when he went first. However, he suddenly remembered that the person on the other side who looked like a student was not actually his student, so he had to put aside his thoughts and start making his own moves.

Ah... I lost my best group of students after that incident.

"In a duel, card resources are of paramount importance! I activate [Pot of Greed and Greed]! Banish 10 cards from the top of my deck and draw 2 cards!"

A quarter of the deck was gone in a flash, but Chronos, who had his hand on the deck, didn't receive a card draw notification.

"Of course I know what you're saying, so I'm taking precautions!"

"I activate the Quick-Play Spell Card I previously set to face down, Masked Change II!"

The dormitory dragon girl, who was on guard duty, looked at the transformation belt that had appeared on her waist with some embarrassment and was at a loss.

"Discard one card from your hand, target Dormitory Dragon Girl on my field, send her to the Graveyard, and Special Summon one Masked HERO monster of the same Attribute with a higher Level than her from the Extra Deck!"

Professor Chronos's face darkened instantly. He knew very well the monster that this card could summon, and he also knew how powerful that card was. In the Fusion Academy, because of their admiration for the original owner of this monster, many people who used the Hero deck would bring that monster that was always trying to make friends with others.

The person who can be recognized by that hero is probably not a bad person. The only remaining question is his origin.

"I'm sending Little Black to the grave, MaskChange!"

"【Masked Hero Dark Claw】!"

[Dark 6★ Warrior 1800 Defense]

In a burst of holy light that obscured vision, the dormitory dragon girl put away her maid outfit, changed into the armor of the masked hero, and assumed a defensive stance. Anyway, as Leyou had instructed, she didn't need to fight. As long as she stood there, no one could ignore her!

Especially its large tail sticking out, it was even more eye-catching.

After transforming, and following the chain reversal, Professor Chronos, with a dark expression, drew two cards from his deck.

"Dark Claw's effect can be activated once per turn if the opponent adds a card from their deck to their hand during their Draw Phase. One random card from the opponent's hand can be banished!"

"As the best teacher at the Duel Academy, I naturally understand the effects of Dark Claw; you don't need to explain it to me!"

"At the same time, I also know how to deal with it!"

Professor Chronos reluctantly took out a red card, which he had originally intended to save for Celestial Sphere, because he knew that monsters with poor attack and defense stats always had noteworthy effects.

But it's now clear that Darkclaw is a more worthwhile card to use against.

"The Trap Card [Infinite Impermanence] can be played manually if there are no cards on the field!"

"Target your Darkclaws on the field! Negate their effects until the end of the turn!"

Dark Claw is very strong, a humanoid figure who can single-handedly dominate the universe, but... no matter how powerful he is, he is still just one of many heroes without any resistance.

With a crack, a bolt of lightning struck, and the electronic dragon Infinite fell to the ground, knocking out Little Black in its Dark Claw form. Le You felt a pang of heartache at the sight.

"As a duelist, you need to have a plan for everything!"

"Now it's my turn to teach you a lesson!!"

"Doing things in the other party's turn isn't always a good thing!"

"Because you activated a monster effect during my Main Phase, I can activate the Spell Card 'Triple Warrior' - Pot of Greed'!"

In short, the image of someone with the face of the Pot of Greed saying they're going to activate the Pot of Greed is truly bizarre.

Chapter 3 is unplayable unless you're almost dead.

(Please, please stop using Crimson King to read this book!)

The Three Battles is an extremely powerful card, so powerful that you can only use it to fight back after someone has done whatever they want to you during your turn.

This description makes the "Three Battles Talent" card seem very erotic.

With the help of this extremely erotic card, Professor Chronos achieved a perfect opening hand of 7 cards.

"Witness the power of my ancient machinery!"

Professor Chronos is now eager to have a proper discussion through a duel.

"Rising from the ruins amidst the roar of machinery!"

"I activate the Continuous Spell Card [Ancient Mechanical Fortress]!"

A massive fortress rises from the forest, enveloping the duel arena. Although it's not a Field Spell Card, the magnificent fortress still exudes an aura of grandeur.

"When the Mechanical Fortress is on the field, my Ancient Gear monsters cannot be targeted by my opponent's effects or destroyed by my opponent's effects during the turn they are Normal or Special Summoned."

In short, it's about resistance to powerful attacks.

"Furthermore, the opponent cannot activate the effects of Spell/Trap/Monster cards in response to the activation of the 'Ancient Gear' card's effect."

Even Sky Striker Princess is incredibly envious.

"Then comes the Field Spell Card, [Gear Street]!"

A massive gear-shaped street rises from the fortress, but anyone who has played the Ancient Gear deck knows that the lifespan of this street is roughly the same as that of the small horned dragons and pterosaurs in the dinosaur deck.

"Next comes the most magnificent creation among ancient machines!"

"Magic Card: Ancient Mechanical Launcher!"

"Depending on the effect, if I control no monsters, I target Gear Street on the field, destroy it, and Special Summon 1 'Ancient Gear' monster from my Deck, ignoring its Summoning conditions."

The launcher emerged from the fortress, slowly advancing, and launched a mechanical giant directly onto the street, completely destroying the newly risen street.

The giants stood tall within the fortress.

"Darling! [Ancient Mechanical Titan - Ultimate Strike]!"

[Earth · 10★ · Mechanical · Attack Power 3000]

"What a powerful monster! It could kill a Blue-Eyes White Dragon with a single punch!"

Leyou had only seen the original Ancient Mechanical Titan and had no idea what powerful effects this fist-enhanced version of the Titan had.

However, it is indeed quite tough.

"My duel isn't that simple! At the same time, the destroyed Gear City also activated its effect! When it's destroyed and sent to the Graveyard, Special Summon 1 'Ancient Gear' monster from your hand, Deck, or Graveyard!"

"I hereby Special Summon the [Ancient Mechanical Body]!"

"The effect of Mechanical Body: Discard 1 card from your hand to activate this effect, search for 1 Spell/Trap Card with the name of Ancient Mechanical Giant."

"I'm adding [Ancient Mechanical Fusion] to my hand!"

This is a major reason why the Ancient Mech deck can become a second-turn OTK deck.

The reason is simple: this is a noble deck fusion!

After receiving the key cards, Professor Chronos did not immediately begin his impressive deck fusion. Instead, after a moment's thought, he asked, "May I ask your name? Based on my judgment, although you are somewhat suspicious, you do not seem to be a bad person."

This somewhat aristocratic but really awkward questioning left Leyou a little flustered. She hadn't felt it when watching the anime before, but now that she was experiencing it herself... Leyou seemed to understand why some students didn't get along with this teacher who was essentially a good person.

"Leyou." He paused, then added to the brief introduction: "An ordinary person."

This put pressure on Professor Chronos, because he genuinely believed that Leyou might be a descendant of nobles like himself.
