The journey of dragon transformation starting from Demon Slayer

The five spiritual beasts correspond to the five elements. They are the white tiger, the gold spirit beast of "Shenra", the blue dragon, the wood spirit beast of "Kushihashi", the water spirit beast Xuanwu of "Dongmon", the fire spirit beast Suzaku of "Hejijima", and the earth spirit beast of "Hyakki" There are five kinds of Huanglong.

Huang Long is currently known to be the strongest, but these have little to do with him, the Red Dragon Emperor. He just recorded the above information and intelligence casually, and did not want to investigate in depth.

When he came to human society before, he negotiated with the "families" of human society, and also tried to visit the "gods" and "yokai" living in this country.

After all, this is someone else's territory. Whether it's out of etiquette or to prevent yourself from being attacked while wandering around this country, you have to visit it no matter what.

However, the visit can only be said to have little effect.

Faced with the "dragon"'s visit, everyone wanted to avoid him, and some gods even ignored him and completely shut him out. There are also some monsters who will chat with this terrifying "dragon" out of fear or fear. Of course, there are also those who are not afraid, but these are the minority after all.

As for the five major families, their perception of him was relatively average. After all, in their eyes, he was a completely foreign object. But in general, the goal has been achieved. At least there will be no picture of being hit by attacks from nowhere while walking around in this country. Just wandering around within someone's sphere of influence will be monitored. This is understandable.

Enjoying the eyes from all kinds of places every day, Tazmi gradually got used to it. He even wished he could point his finger to the sky like Souji Tiandao and make a pretentious statement like "I am the center of the world!"

As for the affairs of the Akeno family, he was not prepared to interfere, and was prepared to wait and see what happened.

Soon everyone arrived at their destination. The group came to the train station closest to home and prepared to take the elevator here to move down.

"down?"

Hearing Rias say that they were going underground, Lyu and the others, who didn't see the downward sign in the elevator, had surprised looks on their faces.

They have been here for more than ten days, and of course they have learned to take trains, cars and other means of transportation, not to mention that Orario also has a "magic stone elevator" that is very similar to an elevator.

Because this station can only go up, it is normal for them to have such a reaction.

For everyone's confusion, Tazmi, who had riding experience, explained it to everyone, and everyone suddenly understood after listening.

It turns out that there is a route specially used by demons underground under this station, and they want to take the underground train to cross dimensions and go to the underworld in this way.

Taking a train is one of the main ways to enter the underworld, in addition to using teleportation magic. But it can only be used for urgent matters, otherwise even if you are the devil, you will have to ride in the car for me.

The reason why it is so strict is mainly because of the special geographical location of the underworld.

Just like there is a universe outside the planet that makes it difficult for life to survive, there are countless dimensional gaps and passages connecting different dimensions outside the underworld, as well as endless "nothingness".

It is difficult for ordinary life to survive there, and only the strong and powerful have the ability to protect themselves.

Moreover, the underworld is set up in a different dimension using special methods, so using different methods to enter and exit can easily lead to various strange phenomena, which may even cause the destruction of the underworld.

Well, the topic of the destruction of the underworld is indeed quite funny. It is just like the earth exploding due to launching a rocket into the universe. Tazmi cannot imagine what it would be like, nor does she think that the probability of this is infinitely close to zero. It will happen before your eyes.

However, in general, it is necessary to enter the underworld by taking the underworld train. It is always not good to enter the underworld through informal means.

And from a side perspective, the means to travel to the underworld are still very rare. Even teleportation requires coordinates. Otherwise, random teleportation will only lead to bigger mistakes and even the possibility of loss of life. From this point of view, if you are not a descendant of a certain demon, there is little hope of going to the underworld.

I heard that in human society there are also some magicians who sign contracts with demons, and they will sign some types of contracts such as bodyguards, transactions, etc.

Some magicians usually sign contracts with famous demons for the technology or knowledge of the underworld.

If it's just for that, you can go directly to the underworld to get what you want, or you can get it through other factions. But the risks are high any other way. Only the devil attaches great importance to equal exchange.

First of all, this method of "getting what you want through other camps" requires paying a relative intermediary fee, and sometimes the price will increase several times. If the knowledge and technology you want are very precious, what you need to pay for may be the wealth gained from a lifetime of research. That is, all property.

For magicians, as long as they sign a contract and complete an exchange of equal value, they can achieve their goal. Sometimes what they have to pay is surprisingly small.

But when it comes to this, someone may ask. Why don't these magicians just go to the underworld?

The reason is still the same, that is, the means to travel to the underworld are quite limited.

Unless you can use teleportation magic to cross dimensions, the only way is to take the Underworld Train.

If you are an ordinary magician, you will be put forward to very strict requirements when taking the underworld train, and you will not even be able to get on the train.

If you are the kind of person who is famous enough to be remembered in the history of magicians, you can indeed get a pass to the underworld, but this is also a very difficult condition.

Leaving a name in history is extremely difficult to see and do.

In general, it is not easy for people other than demons and fallen angels to go to the underworld.

However, it is worth mentioning that just a few days ago, the diplomats from the empire had already left for the underworld in advance!

Although Sirzechs helped endorse it, they still went through a lot of formalities before boarding the train.

He, on the other hand, was a little later and chose to go with Rias and the others during their summer vacation.

Let’s stop the digression here.

In short, there are many places like underground stations in this town, which shows how many demons live in the world.

The elevator in the station only has "1", "2", and "3" floor options. The space is very small. Generally, it can only accommodate five people with full luggage, but if there is no luggage, it can accommodate seven or eight people at a time.

Because Tazmi carries a treasure trove with her, everyone goes out empty-handed.

As Rias took out a card and placed it in front of the electronic board of the elevator, a ding sounded and the elevator began to move downwards until it stopped barely after about a minute.

Soon the group arrived at this vast man-made underground space.

Winnie let out a cute exclamation when she saw this scene, and other people who had never been here also had brilliant eyes when they saw this scene.

The scale here is several times larger than the station upstairs. Just like the comparison between the labyrinth city Orario and the underground city, it is difficult to imagine that there would be such a huge man-made space underground.

The ceiling is far above the head, and the lighting facilities on the wall emit a magical light, illuminating the entire space and lighting the way forward for everyone.
