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

Sixteen years ago.

That was not long after Tetsu Ushio took up his post at the Public Security Bureau. At that time, he was just a newcomer, a young guard at the lowest level of the bureau. He was very ambitious and dreamed of solving major cases and catching the most vicious criminals in a galloping duel.

As a newcomer, his daily work schedule is packed to the brim. At the end of the whole day, he wished he didn't even have time to go to the bathroom. He even had to sit on his police D-wheel to eat.

Sometimes I receive a task just after I start eating, and I have to put aside my lunch that I just finished eating, and immediately rush to the scene on the D wheel.

The most annoying thing is that even if you go all the way at this time, you will only find out in the end that it is all trivial matters and not worth the unfinished lunch.

But overall, Ushio still likes this job.

In those days, D wheels were not everywhere on the streets as they are now, and perpetual motion machines have become an indispensable part of people's daily lives.

At that time sixteen years ago, the first generation of perpetual motion machines had just started operating, and the thing was still quite novel. In contrast, the use of perpetual motion machines to drive the D wheel of new dueling equipment is still a rarity.

If it weren't for his status as a security guard, Ushio wouldn't have been able to buy a D-wheel on his own.

At that time, everyone was ecstatic about the birth of Ment, and the emergence of Galloping Duel pushed the Duel Monsters game to unprecedented heights. At that time, the everlasting colorful light of the perpetual motion machine was the beacon of the entire city, the torch that illuminated the future of human civilization and guided mankind to the path of evolution.

But at that time, almost everyone forgot that although fire could lead mankind to a new future, it could also bring destruction.

The night before, a phone call pulled Ushio out of bed. He answered the phone with sleepy eyes and a bit of annoyance at having his sleep interrupted, and asked angrily: "Who?"

"It's me, Ushio-san." There was a man on the other side of the phone, his voice was anxious and tired.

"Who?" Ushio didn't recognize it and began to wonder if this was a scam call.

"It's me, Murakami. We went to the same high school and when you were on the disciplinary committee, you often stole my lunch?"

Ushio woke up for a while, and an image of a nerd wearing glasses appeared in his mind.

He quickly remembered something and said in surprise: "Wait Murakami? Aren't you being wanted?"

If he remembered correctly, he just saw this guy's wanted poster in the bureau yesterday. However, in fact, he does not need to be a guard to definitely not forget Murakami, because Murakami's wanted order was just broadcast in the news a while ago.

An old classmate who is wanted calls himself, a security guard from the Public Security Bureau? Don't you think you were caught quickly enough?

"I remember you worked for the Kaiba Group before, right?" Ushio frowned and asked, "They said you were selling confidential matters to foreign forces. The Kaiba Group just sent people to the bureau a few days ago and asked us to fully cooperate in the arrest.

You realize it would be a great achievement if I reported you, right? "

Murakami was silent for a moment and said: "I was wrongly accused. What they said was not true at all. The reason why I was wanted was not for selling secrets, but because

Well, the key information is actually blurred in the news. I bet that 90% of what Haima Group told you is false.

But the fact is, until I was wanted, I had been a key technical staff member of the Ment development department. "

Ushio was surprised: "Ment? Is it that perpetual motion machine?"

"The machine that keeps the entire city lit up forever is correct," Murakami said. "That's the department I work for."

"Then why don't they explain?"

"Because during the maintenance work of Ment, I discovered some secrets." Murakami said solemnly, "Some secrets that they tried their best to cover up and didn't want anyone to know.

They wanted it all covered up so much that they would kill anyone who knew the secret. "

"Huh?" Ushio didn't come back to his senses, "Brother, you're not drunk, are you?"

The birth of the perpetual motion machine is an epoch-making milestone in the history of human civilization, marking the beginning of a new era for human civilization. It gives everyone hope for the future.

But it sounds like what this old classmate means is that behind Ment's shining light of hope, there is a darkness that must be covered up even at the cost of blood.

"Whether you believe me or not, this is true."

Murakami's breathing became faster and his voice sounded more nervous.

"It doesn't matter if you don't believe me. But let's do it. At two o'clock tomorrow afternoon, I will give you an address. How about you come here to find me?

You are a guard and I am a fugitive. It should be natural for you to arrest me, right? "

Ushio was even more confused.

"What on earth are you talking about? Why are you doing this?"

"Because I have no one else I can trust." Murakami said, "But before that, you must agree to a condition."

"You go ahead and say it." Ushio said. "Only if you say it, I can decide whether to agree or not."

"You must first go to a place to pick up something, something that is crucial and may rewrite the future of mankind. After arresting me, keep that thing well and don't tell anyone about it."

"Wait, I can't say yes without knowing what it is."

"In short, it's definitely not something involving 'trading secrets.'" He said, "Or, at least wait until you see what it is before you decide whether to agree to my conditions, okay?"

"Uh okay."

The other party had already given in so much that Ushio seemed to be unable to think of any reason to refuse.

And for Oxtail, this is indeed a good opportunity. After all, Murakami is now the key target of the bureau's arrest, and the Kaiba Group has repeatedly put pressure on them to speed up the progress. As a newcomer, if he can be arrested and brought to justice, his future career will undoubtedly be smoother.

So the next day, following the other party's instructions, Ushio rushed to the place he designated and got the things the other party asked him to keep.

Sure enough, as the other party said, that thing seems to have nothing to do with the "trading secrets" charge imputed to Murakami, at least on the surface it seems that way.

That's just a card.

And it's just a whiteboard card, with no patterns or text at all. It looks like it hasn't been printed yet.

Ushio really didn't understand how valuable a blank slate like this was, so he put it in his pocket without thinking too much.

He originally thought that he would wait until the agreed time in the afternoon and see Murakami in person before asking him what was going on with the whiteboard card, but he didn't expect to wait until that time.

Because on this day, a super-large perpetual motion reactor out-of-control accident, known as "zero point reversal," occurred in Shindong Sanye that shocked the world.

The next time Ushio saw Murakami, he was on the list of confirmed casualties in the "Zero Point Reversal" accident.

He never had the chance to ask face to face what the meaning of this blank card was.
