Xiang Shan is gradually becoming aware of a problem. In fact, he lacks understanding of the technological development of this era. The latest knowledge in his mind also dates back to before the Battle of Ascension.

Although this era may seem like a wasteland era, there is no such thing as a "technological regression". The existence of the Scientific Research Knights has kept technology progressing.

It's just that due to the existence of "rivers and lakes", the development of military technology and network security in this era has been somewhat deformed.

But technology is definitely evolving.

Therefore, the hundred-year-old back doors in his memory may not be able to get through the highest level of security system.

It is precisely because he does not know anything about the protocols used in modern times that Xiang Shan cannot venture into the satellite.

Now if you want to get a way, you have to do it yourself.

Draw a map by looking down at the city from above.

Then I have to actually go through it myself to correct the error.

In addition, since it was difficult to enter the Walnut Building and the American-Israeli Building without arousing suspicion, Xiang Shan gave up his plan to explore the upper floors of the two buildings.

But this also means that the city map in his hand must be deficient.

"It's kind of something that can't be helped." Xiang Shan sighed.

This is a very important thing.

That is, "securing the way out".

Just like what Xiang Shan himself said to Yuki, a chivalrous man only has one bad life, so he must cherish this life.

For elite tactics such as "martial arts", it is very necessary to "guarantee a way out".

He had to know what was at his disposal in the city, and where there was a strong armed force and danger.

It's not okay if you don't think about these things.

After coming down from the building, Xiang Shan repeatedly patrolled the streets, measuring the land with his feet and correcting the map in his head.

So far, nothing too serious has been found.

"Next......" Xiang Shan pondered for a moment: "You can consider going to the market to see ......"

In this day and age, the black market was a place where there was everything.

How so...... What is really forbidden by the Dyson principle is only a small number of drugs that are really physiologically addictive, and even ethanol is allowed to be used in a limited way, and most of the materials can theoretically be traded.

The problem, however, is that the Dyson Principle, which states that individuals are only allowed to be loyal to individuals, also prevents the creation of "corporations" – organizations in which "individuals work for legal persons". It is difficult to emerge from various groups related to production and the economy.

As a result, many of the business activities in the market are really on the edge of the Dyson principle.

In a sense, this thing even resembles a green forest.

It exists only because the lords are in no mood to destroy it.

Over time, the people have also developed the custom of "avoiding the eyes and ears of the government as much as possible in all business activities".

Of course, only as much as possible.

After all, the government that sets up a backdoor in everyone's prosthetic body can randomly check anyone's memories anytime and anywhere, so as to know any information.

And these places are also places where chivalrous and green forests get supplies.

Xiang Shan followed the memories left behind by the silver propeller shaft Leif and twisted and turned among the dilapidated houses.

The city's houses come in a variety of styles, from mud and brick to plastic and metal to garbage, making it a slum landscape of different eras of human history.

As you go deeper into the mountain, the road gradually becomes narrower. He quickly turned into a path. It's just enough for two people to go along. On both sides of the road are shack-like buildings, some of which have been converted to the appearance of shops, while others have closed gates. The people who patrol here are careful to keep their distance from each other.

Xiang Shan glanced at the storefronts, but he was in no hurry to buy.

The top quality of this place includes parts, weapons, potions and other resources commonly used by warriors. In addition, there are also those who sell martial arts algorithms. Xiang Shan checked the store's WiFi a little and found that those martial arts algorithms were directly extracted from the blockchain.

But in a sense, this can't be completely an IQ tax. Many ancient martial arts blockchains have become difficult to read due to too many forks and too large. These people combed it through and made it easy to read again, and then took it out and sold it, which can be regarded as a little labor.

"Pay for knowledge" itself is not necessarily something that the "open access movement" has to attack. Xiang Shan remembers that what they objected to back then was "the charge for knowledge itself". However, if someone's job is to search for the parts that customers need from free knowledge and organize them, then this form of "payment" is not unreasonable.

The latter is essentially the creation of value through labor. "Sorting out the parts that a particular object needs from a huge amount of information" is a labor in itself – it can even be defined as a "personalized service".

As long as it is not a monopoly on knowledge and then a fee threshold is set on the knowledge itself, then it can exist.

What his idealistic friends had to do at the beginning was to prevent some powerful people from choking the world's neck with the "knowledge" in their hands and squeezing income out of thin air.

Xiang Shan withdrew from the homepage of this martial arts shop and didn't know much about it. He didn't need any more martial arts algorithms for the time being. I killed a lot of green forests in the wilderness before, and I also got a lot of exercises. Coupled with the content saved from the blockchain a few days ago, he doesn't need to worry about the martial arts itself for a while.

Drugstores are also skipped. He also seized a lot of them on the side of the green forest, where there are drugs to deal with all kinds of brain damage, and he didn't need to think about this for a long time.

And then there's the weapons.

Despite the extreme harshness of the people of the Vault Shelter these days, there is no law prohibiting the production and possession of weapons - no one will manage this unless a nearby Shelterer determines that you are in possession of a weapon in a way that is a strong danger to the safety of those around you.

For example, if you deliver a nuclear bomb or something, you will most likely be attacked by the lord.

Of course, this is also a rule with great discretion. Because the criterion for judging "showing strong harm" is also the mood of the lord.

However, Xiang Shan has no interest in that kind of big killing weapon.

In an era when only a handful of people had usurped the position of the Great Wall, a nuclear bomb would inevitably involve a large number of innocent people.

After visiting several stores, Xiang Shan only replenished some explosives that were difficult to synthesize in the wilderness, a large number of iron blooms, and some functional bullets.

Here we must talk about the most magical settlement method of this era.

They use some kind of digital currency based on P2P encryption.

Yes, not at all.

The main reason is that asylum seekers are not "governments" in the traditional sense of the word, they do not issue currency.

Many of today's currencies are digital currencies made possible by blockchain rules written by Jianghu people.

Of course, it is different from the craze of Xiangshan as a special investment product when he was a teenager.

The fate of blockchain and digital currency is similar to that of 3D printing technology. Before the concept matured, they themselves were reduced to a financial game of capital, and their reputation was overdrawn in advance, and they became synonymous with "deception".

In this day and age, digital currencies have no physical currency tied to them, nor do they have any credit guarantees, which is roughly equivalent to "worthless". It is like a "shell" or "gold" in primitive societies, a "finite number of things born from nature" - the rules of mathematics determine the total number of virtual currencies. The positioning of virtual currency in this era is "the conventional general equivalent".

Digital currency is accompanied by blockchain and P2P technology, and it is naturally loved by the rivers and lakes.

And some of the rules of the digital blockchain have been played. The "mining" of a small number of digital currencies, that is, the operation of "packing blocks", actually helps some knights to establish a martial arts inheritance database.

And because the Dyson Principle prohibits complex organizations, almost all modern financial activities are abolished, and the government does not issue any fiat currency, there is no longer any force to play with this rule.

Therefore, electronic money, with strong anonymity, finally played its due role in this era.

Because the people chose this general equivalent, the government occasionally used it to settle "employment" and "social welfare".

Of course, Xiang Shan didn't have the digital currency of this era, but he had those green forests he had killed before. He dug up the digital currency account from the memories of several green forest people, including the little poisonous insect. It's just that the amount of these digital currencies is very small - most of the needs of the green forest are solved by "grabbing", and the rest of the "barter" can solve most of them.

This money is only used to check and fill in the gaps and buy a small amount of scarce materials, not the flow of Dazhai.

In addition, the leaders occasionally need to go into the city to relax.

Xiangshan is used alone, but it is more than enough.

Due to the strong anonymity of digital currencies, he also does not leave any records.

After supplementing this, Xiang Shan planned to leave the market. He walked straight ahead and passed through a service station.

Mr. Enoch of Recycle Station Town never knew that the service station he frequented had a "black market" at the back door. The murder and arson in the mouth of Silver Transmission Shaft Leif is only a wall away from him.

When Xiang Shan walked in through the back door, the owner of the service station already looked surprised.

Maybe it's a coincidence. A few seconds after Xiang Shan came out of the black market, a person also walked in through the back door. He glanced at the service station owner. The owner of the service station pointed to the gate and spouted Nunu on the left.

The man understood and immediately went out and turned left.

Then, a silver object drew a parabola in mid-air and landed on his head.
