Mysteries: Arcana Wars

Backlund is 681 meters underground.

Dungeon Cotton Alley.

The three followed another receptionist with a camera above her head through a side door and into the corridor.

This is a curved corridor with some room doors open on one side. Klein guessed that the Cotton Alley Exchange should be a circular underground building, and this corridor should be a whole circle, wrapping around the main space of the underground city in the middle.

It seems that the reception hall at the beginning of the entrance is not the only one. There should be another entrance and corresponding reception hall in different directions of the exchange, dividing the entire circular corridor into sections.

As for the signal light outside the corridor, Klein felt that this should be an operation to protect the privacy of guests. When the red light is on, it means that a receptionist is guiding the guests and other guests cannot pass until the guest leaves the exchange or enters his or her room.

Soon the three of them were led into an empty trading room. There was no number written on the door of the room. After entering the room, everyone discovered that the room number was random. Every time a guest changed, the trading room number would be refreshed. Klein also found a refresh button. Even if the guest was still in the trading room, he could refresh his number as he wished.

The three of them sat down in the room, facing a huge trading terminal.

This trading terminal looks very old, a very bulky computer, and even has some technology from the electrical age. It looks like an old-fashioned model from the early days of the information revolution. At that time, computers were not called "computers" and even the Internet that connects the world did not exist.

A small display screen was embedded in the mechanical wall, and a heavy keyboard like a typewriter was connected to it. On the other side of the wall was a huge hole and a mechanical door. This should be a cargo channel for delivering subsequent trading items, and the gold coins would be directly transferred through the account of the Cotton Alley Exchange.

After observing for a moment, Klein walked forward to operate the trading terminal.

The operating capacity of this ancient computer is extremely limited, and the entire trading software is very simple. From the technical perspective of programmers, this should be a trading system built on a local area network and is not connected to the Internet.

It is quite troublesome to access the Internet in the underground city. On the one hand, it is difficult and requires a lot of money to lay network coverage facilities; on the other hand, there are always some shady things in the underground city: if you connect to the Internet, the Internet will also connect to you.

Therefore, only half of the underground cities can find normal Internet connections on the ground, and most of them are located in shallow underground cities more than 500 meters underground. The closer to the ground world, the better the network connection rate. Therefore, the LAN system is widely used in such underground organizations. Of course, there are also many illegal organizations stationed in the underground cities that use dark web technology.

Klein suddenly remembered the advice given by the bartender on Earthworm Island: Don't underestimate the power of "information."

Perhaps this is why the Cotton Alley Exchange chose to use ancient technology: to meet the needs of use while minimizing the exchange of [information].

...Is he afraid that the Church of Steam will come through the network and wipe him out, or is he afraid that other information on the network will be leaked...

or……

...Are you on guard against... [Information] itself...

Some strange conjectures were swirling in Klein's mind, but there was no evidence to support them. He simply ignored them and joined the conversation at the trading terminal to solve the problem at hand.

Although the trading software is very simple, it is like a large chat room with various buying or selling information.

【0158】：Looking to buy East Balam antiques, please discuss the details.

[6523]: Do you want to acquire special abilities? Do you want to conquer the ocean? Do you want to become the best sailor on the five seas? Give me 220 gold coins and I will tell you how to acquire the superpower to sail across the ocean!

Seeing this, Klein couldn't help but sigh: Mr. or Ms. 6523, your advertising slogan is too exaggerated!

At first glance, the atmosphere of this Cotton Alley Exchange was similar to the Beyonder gatherings that Klein was familiar with in the Fifth Epoch. It should mainly be attended by some mid- and low-sequence Beyonders. At the same time, the trading items in Cotton Alley were not only Beyonder characteristics and Beyonder materials, but also other mission bounties, ordinary items, intelligence exchanges, and other items.

For example, the customer 5846 who was looking to buy a large number of rare and exotic animals, his shopping list included at least three main ingredients for the sequence nine magic potion formula, including sailors, singers and audiences.

Thanks to the blasphemous A4 paper provided by the illusion Melissa, I was able to fill in the gaps in the potion formula and potion name.

And the guest 0158 might just be passing by and looking for some antiques for fun.

In general, the overall level of this exchange is not high, and it is rare to see Beyonder characteristics or potion materials and formulas above Sequence 7 or Sequence 6 being traded.

After roughly understanding the current prices of Beyonder items, Klein used all of his few Sequence 9 and Sequence 8 Beyonder characteristics. Seeing his card balance suddenly become richer, a long-lost happiness surged in Klein's heart.

This feeling, which was very similar to his memories of the Fifth Epoch, finally allowed Klein to find some sense of reality in entering the Extraordinary World. The flashing transaction notices were like the small notes passed by waiters at the Extraordinary gatherings of the past. This familiar experience gave Klein a rare sense of security, as if proving to him the reliability of his memories of the Fifth Epoch.

The process of submitting items is also very simple. After operating on the transaction terminal, the door on the wall will open. After the goods are placed in the huge capsule, the electromagnetic track will send the capsule to where it should go.

From this point of view, Cotton Alley is a smaller underground city. The center of the entire exchange is the invisible huge electromagnetic capsule system inside, and outside are some operating cabins, guest corridors, and other use spaces.

After obtaining the first principal by selling extraordinary characteristics, Klein looked at the pleasing amount and began to select the next purchase object.

At this moment, a message board jumped onto the screen, attracting Klein's attention.

[7546] Out: 3 copies of Roselle's diary. PM me if you want them.
