At the beginning, I traveled through Cheng Qisara to the DM world

Yami Yugi and Kajiki Yuta board the duel machine together.

"I don't know your name yet." said Kajiki Yuta.

"Muto Yugi!"

"Yugi, take out your bet. How many metal stars do you want to bet?"

"I bet three metal stars!" Dark Yugi directly took off all his metal stars.

"Then it's the same for me." Kajiki Yuta also put down the metal star.

"The bet is set, let's start the duel!" said Kajiki Yuta.

"Duel! x2"

Dark Game LP4000

Kajiki Yuta LP4000

"Yugi, I won if you attack first!"

"It's my turn, draw a card!" Kajiki Yuta drew a card.

"Activate the environmental magic card [Legendary City - Atlantis]!"

This card's name is treated as [Sea] in the rules. Increase the ATK and DEF of all Water monsters on the field by 200. While this card is in the Field Zone, reduce the Level of all Water monsters in both players' hands and on the field by 1 point.

"The level of [Sea Dragon God - Leviathan] in my hand is 5. Due to the effect of [Legendary City - Atlantis], its level becomes 4, so I can summon it directly without releasing the monster."

"I summon [Sea Dragon God - Leviathan] in Attack Position!" (2000/1700)

"Due to the effect of the Circumstance Spell Card, attack and defense power increase by 200 points."

[Sea Dragon God - Leviathan] (2200/1900)

"Activate the special effect of [Sea Dragon God - Leviathan]. During your Main Phase, you can add one of the following cards from your deck: a Spell/Trap Card with [Sea], a [Sea Dragon God], or a Spell/Trap Card with [Underwater]."

"I add this [Sea Dragon God's Blessing] to my hand, covering two cards. End of turn!" (Hand remaining: 3)

"Yugi, I have one more thing to remind you. As long as [Sea Dragon God - Leviathan] has [Sea] on the field, each team can only have one face-up monster other than Water on the field."

"So I can only summon one battle monster other than water attribute? The monster that sealed me is deployed?" Yugi asked in surprise.

Seeing what Kajiki Yuta did, Kisara frowned, "System, are you there?"

"I'm here, host. What's up?"

"Why is Kajiki Yuta able to use such powerful cards in the appearance phase? The same goes for Yuga, Ryuuzaki, and Peacock Dance before him. They all used cards that were ahead of their time."

"Host, due to your intrusion, this game world has secretly upgraded everyone's level to prevent you from overwhelming them, which is why this situation has occurred."

"I see. Because of my appearance, this game world has to be upgraded."

"My turn, draw a card!"

"I activate the Spell Card [Angel's Charity] from my hand, draw three cards from my deck, and then discard two to the Graveyard."

"Activate the special effect of [Dark Demon Kilfar Demon], a monster that enters the Graveyard. This card enters the Graveyard and becomes an Equip Card. It is equipped to a monster on the field, and its ATK decreases by 500 points."

"I equipped the [Dark Demon Clan Kilfar Demon] on the [Sea Dragon God - Leviathan]."

[Sea Dragon God - Leviathan] (1700/1900)

"I activate the magic card [Resurrection of the Dead] from my hand!"

"Special Summon [Black Magician] from the Graveyard!" (2500/2100)

"I activated the Equip Spell Card [Illusionary Scroll] from my hand and equipped it to [Dark Magician]. This card's effect can change the equipped monster's attributes, so I changed [Dark Magician's] Dark Attribute to Water Attribute."

"This will allow me to summon monsters of other attributes, and with the effect of your environmental magic [Legendary City - Atlantis], my [Black Magician]'s attack and defense will increase by 200 points," Yugi said.

Black Magician (2700/2300)

"So there's a way to do this." Kajiki Yuta glanced at his covered cards, "But this alone isn't enough."

"I know. I activate the magic card [Bond of Master and Disciple] from my hand. The effect of this card is that when I have [Dark Magician] on the field, I can Special Summon [Dark Magic Girl] from my hand, deck, or graveyard. After that, I can choose one of [Dark Magic], [Dark Magic Explosion], [Dark Explosion Magic], or [Dark Magic Combo] from my deck to place on my board."

"I chose [Dark Magician]!"

"Activate [Dark Magician]! This card can destroy all of your opponent's Spell and Trap Cards while there's a [Dark Magician] on the field!"

At this time, Kajiki Yuta was a little panicked and quickly opened the cards.

"Don't even think about it. Activate the Counter Trap Card [Magic Interference Array] and discard a card from your hand to negate and destroy your Spell Card!"

"I see. You're trying to stop me from destroying the backfield? Then I'll use [Dark Magician] to attack [Sea Dragon God - Leviathan], Black Magic!"

"Activate the Continuous Trap Card [Tornado Sea Wall]. As long as [Sea] exists on the field, the battle damage you receive is 0."

A towering wall of water rose from Kajiki Yuta's field, blocking the black magician's attack.

"But your [Sea Dragon God - Leviathan] will still be destroyed! Two cards are covered, and the turn ends!" (Remaining cards in hand: 1)

"It seems that the game has evolved." Qisala thought to herself.

"My turn, draw cards."

"I summon a monster in Defense Position, covering a card. This turns ends." (Hand remaining: 1)

"My turn, draw a card!"

"Fight, [Dark Magic Girl] attacks the dark guarding monster, Dark Magician Explosion!"

"Activate the Trap Card [Divine Protection of the Sea Dragon]. During the turn this card is activated, Level 3 and lower Water monsters cannot be destroyed by battle. Yugi, you cannot destroy my monsters this turn."

"Tsk, this is tough, turn over!" (Remaining cards in hand: 2)

"It seems that Kajiki Yuta will have to use his ace monster this round." said Kisara.

The others also understood Yuta's intention to keep his monster, which was undoubtedly as a sacrifice to summon a higher-level monster.

"My turn, draw a card!"

"Due to the effect of [Legendary City - Atlantis], the Level 7 monster [Sea Dragon - Taydar] in my hand becomes Level 6. Therefore, I liberate this monster on the field and summon [Sea Dragon - Taydar] from my hand." (2600/1500)

"You can activate the special effect of [Sea Dragon - Tadalus] by sending 1 face-up [Sea] card you control to the Graveyard. Destroy all other cards on the field except this card."

"I send [Legendary City - Atlantis] to the Graveyard. Yugi, all cards on your field are destroyed!"
