The journey of dragon transformation starting from Demon Slayer

"The things I think I have done cannot be exchanged for your great help. Anyway, I will remember your kindness."

His tone was very serious, and he looked at the boy deeply, as if Tanni wanted to imprint Tazmi's appearance deeply in his heart.

At this moment, a train that looked like a train suddenly rushed out from the portal that opened in the sky. Its appearance was even more unique than any train Tazmi knew.

Tazmi looked from a distance, and with the help of his excellent eyesight, he saw the whole train.

The train speeding through the sky is engraved with patterns representing the devil. There are Gremory's family lines and Sirzechs' Demon King's lines.

If he remembered correctly, this fiery red train was the Gremory family's private train.

In the underworld, there are many trains connecting the human world. Both demons and fallen angels have such things, and some of them are like ordinary trains. After traveling through space, they drive directly along the railroad tracks into the train station in the human world. Even the fuel used is a specialty of the underworld.

Of course, these trains are only responsible for receiving demons. Basically every family of the Seventy-Two Pillars Duke has a private train. Ordinary people would never be able to see these things that only belong to demons.

Originally, Tazmi thought he would take an ordinary train to the human world, but he still underestimated Sirzechs' importance to him. Or maybe they underestimated the importance of the "Red Dragon Emperor" in their eyes.

The train was traveling in the air, and its height and speed were slowly decreasing. After a while, Tazmi saw the train that was still traveling in the air stop in front of the platform where he was.

The door of the train slowly opened, and then a male devil wearing a conductor's uniform and a female devil they had just met walked out of it.

The female demon is Sirzechs' maid Gurefia. Her beautiful silver hair is tied into braids and hangs down on both sides of her face. Her beautiful face and proud figure, covered by a maid outfit, inadvertently stir people's heartstrings.

"Long time no see, Lord Tanni. Lord Sekiryuutei. x2"

"Hello, Miss Greyfia."

"Yes. Long time no see, the 'Queen' of Sirzechs."

One person and one dragon greeted the silver-haired maid, and then looked at the male demon standing beside the maid.

The other man looked slightly older, but his tall and straight body wore the dark uniform straight.

"First meeting, Sekiryuutei-sama. I am the conductor of this Gremory train, Leonard. Please give me your advice in the future."

"Hello, Mr. Leonard."

He solemnly took off his hat and bowed to one person and one dragon. When he saw the other person coming to pick up Tazmitani, he also responded and greeted the other person as if nothing had happened.

"Long time no see Leonard. The last time we met was about seventy or eighty years ago."

"Seventy-six years to be precise. Lord Tanney."

"Haha, it's almost the same. But I didn't expect Sirzechs to use his own private train. If so, I could actually send him to Gremory's territory."

Tazmi's information was reported by him, and he was not surprised that Sirzechs would take the news seriously. After all, he is one of the hosts of "Celestial Dragon". Moreover, he is a hybrid of "human" and "dragon".

What surprised him was that Sirzechs would use the Gremory family's private train to send Tazmi to the human world.

This train will only allow members of the Gremory family or Sirzechs himself to ride. Besides that, there are other nobles from the underworld who are free rides. And it was the first time that Tazmi could sit on it as an outsider who was not even a demon.

"Tazmi. This must be your first time seeing such a thing. Aren't you curious?"

Turning his head to look at Tazmi standing aside, Tanni flew in the air and asked with a smile.

He didn't know that Tazmi and Rias had taken such a train together when they returned to their hometown in the underworld. Of course, Tazmi would not take the initiative to reveal this memory to others.

"Um...Uncle Tanney, you probably don't go to the human world very often...this thing is actually not much different from the train in the human world..."

Tazmi twitched her lips and explained to the purple flying dragon next to her.

Apart from being able to "jump through space", "break through dimensional walls", "driving in the air" and so on, the rest is indeed similar to ordinary modern trains.

"Haha, really. Then I have indeed stayed in the underworld long enough. If I have a chance, I'd better go out and have a look."

I think it’s better to forget it. If you show up in the human world, you might make headlines immediately.

Muttering in his mind, Tazmi twitched the corners of her mouth and imagined what kind of huge commotion Tanni, the dragon, would cause when it appeared in the human world.

Monsters invade reality, Ultraman...why is Ultraman involved again? Forget it, forget it, don't think about it too much.

Shaking her head helplessly, Tazmi added.

"And I've seen things even more outrageous than this..."

As he said, the "Supreme" that has been "reduced" in size is now lying in his treasure house. That thing is much bigger than this train. If you show it to Tanney, he will definitely say that he has never seen such an exaggerated thing.

I really don’t know how the First Emperor made something so big move.

This was the confusion he had in his heart when he was studying the Teigu. What was the technological level of the empire a thousand years ago. Newton and Einstein were moved to tears after reading this.

"Then I'm going to get in the car first, Uncle Tenny..."

"Yeah. Be careful on the road."

He turned around and waved to Tanni, and Leonard, who was standing not far from the train door, asked Tazmi to take out the card with his login information in the underworld for confirmation.

This thing is like an ID card in the underworld. It's like the information of people reincarnated by demons has been registered in the underworld by themselves when they get the chess piece and are reincarnated. Information is very convenient.

It's just that people like him have to ask someone to register, but it's not too troublesome. It's almost the same as applying for an ID card normally. Personal photos and information required.

Without papers he could not board the train. It's the same as being a gangster in human society. It is not an exaggeration to say that it is difficult to move even an inch.

At present, he has no such person in this world, and doing this can be regarded as planning for the future.

As for whether doing so will expose personal information?

Tazmi felt it didn't matter anymore. Exposed is exposed.

After all, I'm not from this world. If you want my fake home address, can you still give me warmth?

Those who achieve great things are not careful about the little things.

Taking out a card the size of a bank card from the ripples in the air, Tazmi walked slowly towards the commander Leonard.

"Although it is a temporary certificate, it is better than nothing... Sorry to trouble you, Commander."

He was talking to himself. This is the first time he has opened his treasure house in front of outsiders.

Seeing the young man's method of retrieving objects from space, the three demons present were speechless.

"Yes. It's confirmed that it's Tazmi."

"This trip to the human world will take about sixty minutes."
