Mysteries: Arcana Wars

Backlund is 669 meters underground.

Dungeon Night Harbor.

This was a very safe distance for Klein. He could still control the doll on the ground. Although the doll couldn't be too far away from him horizontally, he could exchange positions with the doll at any time and run away.

If Leonard and Fors were not accompanying them.

At times like this, it becomes clear how important it is to have an apprentice teammate, especially in times of crisis, when he can lead everyone to escape together.

Unfortunately, the apprentice angel at hand is still a dud.

Thinking of this, Klein suddenly felt insecure about escaping.

...It is said that Leonard now has three pairs of hands. So, should he hold me and Fors, one on each side, and run at full speed to make us faster...

If "subsidence" or "landslide" occurs, we can even have a few more hands to dig the soil...

Jokes aside, it can be seen that the customs of the people in Yongye Port are indeed not very simple.

According to Leonard's previous introduction, the closer the underground city is to the surface, the better the connection with the ground can be maintained. The deeper the underground city is, the more it is out of touch with contemporary society and the more difficult it is to interact with the ground.

In Backlund's current urban development, the area 200 meters underground is still an area of ​​human civilization and a part of the ground order, including underground buildings, underground equipment, underground pipelines, and underground transportation.

Of course, due to the irreversibility of underground space development, since the advent of the information age, abandoned underground spaces made of reinforced concrete have been preserved from the ground to about 200 meters underground. These spaces are connected to the social order on the ground, but the entrances are hidden, and the official forces from Backlund can still explore them.

These places cannot be called real underground cities, but are just a transition between the orderly and civilized above-ground society and the chaotic and disordered underground world. Sivelas Field calls them the "Edge Zone".

Backlund was not without slums, but the low rent, specific policies, and subsidies that were better than nothing, as well as all the services and support from the modern city machinery, were based on one condition: having a legal residence status or Loen identity information in the system.

In the [Edgeland], most of the residents here are illegal immigrants from all over the world. They risked all kinds of risks to come to Backlund, thinking that the "Land of Hope" was an ideal place, but in the end they found that they were just scum that was eaten up and discarded underground by this huge monster.

Of course, there are also many "poor people" from other places in Loen in the [Fringeland], but due to policy restrictions, they cannot apply for slums in Backlund. The system identity that was originally a guarantee of policy has now become a shackle that restricts them.

Sadie Russell, the thief who reported the crime to Leonard at Sivellas Field, is a typical example of a resident of the "Fringeland".

The rest is the dark side of the world above ground. Many criminals and illegal groups have moved their covert activities to the [fringe areas] to escape official pursuit and the control of the city system.

Therefore, the Sivellas Field will not rashly enter the [marginal areas] where the composition is chaotic and the situation is complicated, but when necessary, these government forces will still not hesitate to strike the marginal areas.

And from the marginal areas down, where the social order is gradually losing control, is where Backlund's long-accumulated illness lies.

Settlements between 200 and 500 meters underground began to be called real underground cities, that is, shallow underground cities. These underground cities no longer rely on the system of the surface society, but gradually generate their own closed systems. People living in marginal areas are often closely connected with the surface, such as going to the surface every day to do some illegal work or commit crimes, but starting from the shallow underground cities, there will be people living steadily underground, only going to the surface to buy supplies when necessary.

The entrances to these underground cities are very hidden, and there are few direct passages from the surface. One often has to enter from underground buildings still in use by the society above ground, or find downward passages in the marginal areas. These buildings are not very old, and most of them are products from the end of the electrical age to the information age. They are often buildings that were disconnected from the aboveground world due to natural disasters or extraordinary disasters, and then after "settlement", the ruins settled downwards and reached this depth.

Klein recalled the history textbooks he had studied during his student days in the Sixth Epoch.

Although the people of Loen were extremely enthusiastic about developing underground space after entering the Sixth Epoch, the history of development was very difficult. In the more than 1,300 years of the Sixth Epoch, in addition to the relatively minor damage caused by the [Sky Curtain Disaster], there were also several large-scale disasters that caused great damage to Backlund's underground space.

Now Klein can conclude that these major disasters are extraordinary disasters, just like the "Sky Disaster" three hundred years ago was actually an extraordinary war against the Outer Gods.

The old subway that Backlund was so proud of now was not the first one built after the end of the Sixth Epoch. After the Second Steam Revolution, the great tracks powered by the Rama steam engine had long been buried underground due to landslides in the next major disaster. Due to the limitations of engineering technology and extraordinary disasters, the subway system experienced several large-scale landslides and was rebuilt many times. The current subway was actually initially finalized at the end of the electrical age.

Most of these underground ruins that collapsed during the electrical age are now located at a depth of about 500 to 1000 meters below Backlund, becoming the middle-level underground city.

Here, the order on the ground is completely invalid, and all the order in the dungeon is decided by the controller of the dungeon.

It was also from here that all the criminals became "serious". Most of the crimes in the marginal areas and shallow underground cities were small-scale, and the people there were still mostly ordinary residents, or just looking for a place to live. In the middle underground cities, more and more "professional" criminals were active here, including smugglers, gangs, black markets, drug manufacturers, killers... The criminal activities here began to become organized and disciplined, and the people who did these things were often engaged in a certain black profession or had some stable gangs.

When these dark forces grow to this scale, it means… In the middle dungeon, you can have initial contact with the extraordinary world.

Judging from the markings on the small door just now, Evernight Harbor is 669 meters underground and belongs to the middle-level underground city.

Klein thought of the few low-sequence Beyonder characteristics he had on him. Fortunately, he took them with him before he went out today. At that time, he was just a crazy adventurer, so he had to at least have some confidence that he could use Beyonder characteristics anytime and anywhere. Now it seems that if he is lucky this time, he can find a Beyonder gathering to exchange them for some money, and then find some other Beyonder items that suit him.

The middle-level underground city was composed not only of landslide ruins left over from the electrical age, but also of abandoned mines like Evernight Harbor—who knows what they could have dug up underground in Backlund at that time!

As for the area below 1000 meters...

The deeper you go, the fewer suitable ruins you will find, and the less people will go there. Some say that there are ruins from the Steam Age of the Sixth Epoch buried there, some say there are treasures from before the Doomsday Disaster of the Fifth Epoch, and some say there are mysterious buildings that suddenly appeared underground...

The underground cities that may exist below 1000 meters are collectively referred to as:

Deep dungeon.
