Who asked him to play Yu-Gi-Oh!

Chapter 1671 New Regulations
One day later, Yu Xuan returned to the world of GX from the Synchro Dimension.

Upon returning, he didn't rest for a moment. He immediately gathered all the Duelist teammates he had found from various dimensions, indicating that he had important matters to explain.

"The rules of the duel?"

Youma scratched his head.

He felt a headache coming on whenever he heard about rules. Learning the rules of the game in his own world was already a huge struggle—if he hadn't struggled to even understand the basic rules, the leader's incredible luck in drawing cards wouldn't have allowed him to maintain his undefeated record among his classmates for so many years.

"Well, we already know how to duel," Yuma said. "There's no need to go and learn the rules again, right?"

The astral body reminded, "Yuma, since Yu Xuan specifically said this, there must be something we don't know."

As he spoke, he and the others turned their gaze toward You Xuan.

You Xuan nodded and said, "Yes. I just confirmed the location of the target dimension. Next, we will head to that place called 'Academy'."

"Oh! So we're finally going!?" Jaden looked full of fighting spirit. "I will never forgive those who do evil under the name of Duel Academy!"

“Yes, but before you go there, there are some things you need to know about the duels in that world,” You Xuan said earnestly. “Generally speaking, the rules of the duels are the same as what everyone knows, so I will only point out some of the more important key differences.”

"Wait a minute, Senior Yugen." The good student, Fudo Yusei, raised his hand to ask a question.

You Xuan nodded to You Xing: "You Xing, you speak."

“I understand that the rules of dueling may differ between different worlds. But do we have to adapt to their rules?” Yusei asked. “Because when the people from the ‘Academy’ invaded the Basic Dimension into Mr. Game’s world, they also followed the rules of the Basic Dimension in their duels, didn’t they?”

You Xuan nodded in approval: "You Xing raised a very good question, so I will answer and explain it to everyone here. The reason why the enemies in the 'Academy' have followed our rules in the basic dimension and many other interdimensional battles is because they are the invaders and we are the defenders."

The game developers were the first to understand: "I get it! Because they live in our world, they naturally have to follow the rules of our world."

Judai pondered for a moment: "Does that mean we now have to actively enter the other party's world, so we have to play according to their rules?"

“Yes,” You Xuan said. “Even summoning techniques are similar. In a dimension where the conditions for the formation of summoning rules do not exist, certain summoning techniques cannot be used unless we have special abilities or equipment to make those summoning rules work.”

He glanced at Yusei's D-Wheel as he spoke, and continued.

"For example, Yusei's D-Wheel has a perpetual motion machine built in it, which can naturally generate Yusei particles. This allows the existence of Synchro to be recognized in a world that originally did not have the rule of 'Synchro Summoning'."

Yuma exclaimed in surprise, "Eh!? What if the world we're going to doesn't support Overload?"

He immediately realized that most of his deck's strength came from Xyz Summoning. Well, to be more precise, it all came from Hope.

What if the places I go to don't exceed the limit? Wouldn't I just become a noob?

In fact, back in Yu Xuan's dimension, if Zorc hadn't interfered, weakened the barrier between the two worlds, and introduced the concept of "Xyz" into the fused dimension, Xyz wouldn't have been usable in this fused dimension.

“There’s no need to worry about that,” You Xuan said. “The dimension of the ‘Academy’ we’re going to already has the rules of ‘Synchro’ and ‘Xyz’ at least simultaneously.” He didn’t specifically mention Fusion, because Fusion needs no further explanation. It’s compatible wherever there are cards to play, making it the most adaptable Extra Deck Summoning method in all the universes.

"Oh, I see." Yuma patted his chest, seemingly relieved. "I was so scared, I thought I wouldn't be able to use the overdose."

The astral body gently reminded him, "Actually, there's no need to worry, Yuma. We possess the power of 'ZEXAL,' and in any world we go to now, we should be able to unleash an extraordinary amount of power."

In other words, I have a cheat code.

ZEXAL is a power involved in the origin of the Xyz world. Duelists of the Xyz dimension can't use Xyz casually in another world, but Yuma and Astral are different. They are comparable to thousands of masters and have their own Xyz network wherever they go.

While others use excessive amounts of data by merely borrowing the laws of nature, they possess their own inherent laws. Others are simply riding on their coattails.

"So, let's go back to the differences in rules between dimensions, and the most important point is the first one."

You Xuan paused, then lowered his voice and emphasized.

"In the 'Academy' dimension, it's very likely that you can't draw cards if you go first in a duel."

This change was like a bombshell for all the Duel Kings of all time. They looked at each other in disbelief, each of them finding it somewhat incomprehensible.

"Huh? You can't draw cards when you go first?" Yuma exclaimed in surprise.

Even the game was puzzled: "But going first inherently puts you at a disadvantage because you can't attack. If you also have one less card than your opponent, wouldn't going second give you an absolute advantage?"

Their reaction mirrored that of many card players when "Master Rule 3" was first introduced.

Especially for veteran players who have been playing cards for twenty years, the sudden news that they can no longer draw cards when going first might leave them completely dumbfounded, giving them a sense of alienation as if Yu-Gi-Oh!, which they grew up with, has suddenly disappeared.

However, in reality, even with such a severe nerf, going first still holds an absolute advantage in the new era of Yu-Gi-Oh!

The reason is simple: the first player can set up the board in advance.

I'll go first and talk for ten minutes, then unleash an invincible effect that knocks out three to five of your cards in one turn, followed by a quick bombardment of four or five of your cards in the final round. By then, my opponent has essentially been stripped of their right to play Yu-Gi-Oh!, and having one more or one less card seems irrelevant.

The rule that the first player cannot draw a card may seem like just a change in the rule of a single card, but it actually reflects that the game has entered a new era where "only one person can play".

"That's probably the most crucial point, and there's another one," You Xuan said. "Regarding Field Spells. Starting from the new era, both sides are allowed to have one 'Field Spell Card' on the field at any given time, meaning a total of two Field Spells can exist on the field simultaneously."

In other words, the familiar tactic of 'using field spells to displace the opponent's field' would likely be useless in that dimension.

Everyone: "!"
