I'm playing cards in Yu-Gi-Oh!

Haima Group, whether it was in the old Tongshiye or the new Tongshiye built on the ruins after the "zero point reversal", is a landmark building that represents the soul of the city.

Although President Seto Kaiba may not be said to be the patriarch and founder of the Kaiba Group, no one would have any objection if he was said to be the most successful and far-reaching president among the group's past presidents.

He single-handedly transformed the Haima Group from an arms group into a company focusing on card and card entertainment. He even used this as a basis to vigorously promote his beloved card games around the world, and even made great contributions to the progress of human civilization. .

Especially after the epoch-making first perpetual motion machine Moment built by Haima Group was put into operation, Haima Group became the core of the world. Since then, every aspect of human civilization has been inseparable from Moment. It can be said that Haima single-handedly determined the future direction of the world.

This is true even to this day.

Whether it is the duel monsters that are now popular all over the world, or Moment, the energy core that supports the entire human civilization, Haima technology can be found everywhere in this future society.

So you can imagine how surprised Yu Xing was when he heard Yu Yu's request.

"The Kaiba Group is the most secure place in the city." Yusei explained, "Now that I am a wanted criminal, there is no way I can get in."

As soon as he heard the words "high security level", You Yu couldn't help but feel happy.

What is the security level of Haima Group? Isn't it on the same level as a public toilet?

"Don't worry, I know their security facilities quite well." You Yu said, "In addition, I know there are several hidden security loopholes...

...Well, I can't say it's a loophole. To be more precise, maybe it should be said to be a backdoor. He is the president of Kaiba Corporation...

...I mean, the former president Seto Kaiba left it behind just in case. "

In the Oriha Gang chapter of the original animation of "Yu-Gi-Oh! DM", when the Kaiba Group fell into the hands of Datsu, President Kaiba took Yugi and others through a secret door in the underground water system that only he knew about. Infiltrate the Kaiba Group.

There are actually two or three similar secret doors, and You Yu knows the specific locations.

Yusei was a little impressed when he heard this: "Senior Yuyu, you actually know all the secret doors left behind by the previous president. In your time, you and the legendary President Seto Kaiba should have been life-and-death partners, right? ?”

"Don't talk nonsense." You Yu rolled his eyes at him, "He is the boss and I am the subordinate. It's just that I am more capable, so the boss tells me a little more, that's all."

"Yes...that's it."

Yusei still felt strange, thinking that no matter how much trust he had, he wouldn't reveal all his trump cards to his subordinates, right?

Of course, he is a highly respected senior, and we are just a nobody. We can do whatever the big boss says. We don’t dare to say or ask...

So Yuxing didn't say much and drove the D wheel to the drain designated by Yuyu.

You Yu is actually not sure whether the secret door is still there after so many years and a disaster like the "Zero Point Reversal". But now it seems that he is lucky, at least the entrance is still here.

Yusei parked the D wheel in a relatively hidden shadow on the side of the road, then opened the heavy cover of the sewer shaft and climbed down the escalator.

When the lid was lifted, a stench came out of it, like something rotten after being soaked for decades.

The ladder was also badly rusted and was shaky when Yusei climbed down. The sharp squeaking made people couldn't help but suspect that it might not be able to bear Yusei's weight and collapse every second.

It can be seen that no one has come down here for many years.

Yusei reached the bottom, and the water below reached the heels of his boots. The feeling under the stagnant water is soft and sticky, like sticky mud that has been soaked with rainwater.

"Mr. You Yu, are you sure this is the place?" He couldn't help but ask.

"Well... the place is definitely right. I don't know if the door is still there or not." You Yu said, "Anyway, let's go take a look first."

The passage ahead was so dark that one couldn't even tell the direction.

Yusei groped around on his body and found that there seemed to be no equipment that could be used for lighting. Just when he was in trouble, a golden light pierced out from behind him like a sharp sword, illuminating the wet pipe in front of him.

Yusei turned his head and was surprised to see a fair-skinned and beautiful magician lady beside him. She has blond hair, a cute face, slender arms and white thighs, and the light source comes from the small staff she is waving in her hand.

She winked at Yusei and said a lively hello.

"This is...the Dark Magician Girl?" Yusei quickly recognized this legendary monster.

"It's me." The dark magician girl smiled, holding the small staff across her hands, and bowed in a standard big and white bow, "Please give me your advice!"

"Please give me some advice..." Yusei looked at the ghost floating beside him, "Is this your monster, Mr. Yuyu?"

"Yes, it's my elf."

It has been tested with Masked Heroes in duel venues before. You Yu's current state is similar to that of traditional back-end spirits such as Wang Yang, Tapirang, and Liu Sui'er. Although he has no physical body, his extraordinary power can still be used, so the monsters they summon can be materialized.

But the difference is that Wang Yang and Xi Liang can use the bodies of their possessed hosts to fight online, but You Yu doesn't seem to be able to.

He speculated that it might be related to the fact that the object he possessed was a duel disk...

"It's the lighting spell I cast." The black magician girl proudly puffed out her majestic chest and said "Well, I'm awesome" written all over her face.

"Yeah, that's great." Yusei praised sincerely.

"That's all." You Yu muttered vaguely.

The passage seemed to be in a state of disrepair, and there were many cracks and signs of damage on the walls along the way.

Yusei speculates that these may be caused by the "Zero Point Reversal" accident. It's just that the Haima Group's construction technology is very advanced and of high quality, and this is not the center of the "Zero Point Reversal" outbreak, so the passage has not collapsed over the years.

Fortunately, the secret door set up by President Kaiba is still here.

Since no one has come in for so many years, naturally no one will notice the existence of this door, let alone change the password to open the door.

After Yusei entered the password that Yuyu told him, the metal door covered with cobwebs opened clumsily to the two of them.

Behind the door was an elevator, and Yusei walked straight in, letting the elevator carry him all the way up.

Yusei couldn't help but said: "No one would have thought that the Kaiba Group with its airtight security system would actually have a hidden entrance in a place like this..."

You Yuxin said that's because you don't understand. The Haima Group is as leaky as a sieve, but in fact there is no shortage of such backdoors...

There is no floor option in the elevator. After pressing the start button, it will automatically take them all the way up.

I don’t know how many floors I went up, but the metal door automatically slid open.

They have arrived inside Kaiba Company.

Behind the door is a long corridor with incandescent fluorescent lights on the ceiling. And in this corridor...

...There was also a man dressed as a security guard in the corridor, looking at Yusei in surprise.

"Who are you? Where did you come from?"

Yusei: "..."
