Ten years ago, the world entered the end of the world, as the mutated creatures became more and more powerful, the human living environment was further oppressed, and began to build cities and live in the survival mode to resist disasters, and the population gathered in the city, gathering all human and material resources to make the final struggle for human survival.

Therefore, now the whole world is full of large and small cities, and more than 90% of the world's population has gathered in various cities, relying on solid walls to resist the attacks of mutant beasts to gain a chance of survival.

It is precisely because of this that six years ago, humans dared to launch powerful nuclear bombs and other weapons to eliminate the mutant beast group, as long as they were not dropped into the cities inhabited by humans, they were not worried that the weapons dropped would hurt too many humans.

It is worth mentioning that although it is true that six years ago, human beings did destroy countless mutant beast groups and kill countless mutant beasts around the world, but after the nuclear bomb and other high-power weapons were dropped, not only did the dust cloud cover the sky, but all kinds of radioactive elements flooded the world, causing other animals to get a second mutation......

If you don't do that, human beings will be in danger, but the second evolution of all things will be helpless.

Because human beings build cities and live, only by staying in the city can people feel a sense of security, so every resident of the city, must have a residence certificate, if not, it is an outsider, want to enter the city to seek a place to live and live, the first time you enter the city, you must pay the corresponding fee, this depends on the situation of each city, and so on.

Of course, if you do not apply for a residence certificate after entering the city for the first time, you still have to pay a certain fee for entering the city for the second time.

At this time, Huang Yi and Yue Yuan were intercepted by the guards of Liyu City and demanded to pay the fee.

Huang Yi and the others entered the direction of the city at this time. The city wall is about eighty meters high, reinforced concrete is poured, and there are guards standing guard on the city wall, erecting anti-aircraft machine guns, energy cannons and other weapons, always paying attention to the movements of all parties, ensuring that the mutant beast is killed as soon as it appears.

Liyu City has a population of more than 100,000. The city wall is tall, several kilometers long and right, and you can't see the end at a glance, like a giant dragon lying on the ground, which makes people feel at ease and feel safe.

The gates of Liyu City are ten meters high, and they are completely made of heavy metal, half a meter thick, once closed. At least it can withstand the impact of the Candidate Mutant Beast, of course, it is open at this time.

There are two rows of soldiers at the city gate, ten people at a time, wearing pitch-black armor with fists, wrapping the whole person tightly, with long knives at the waist and firearms with great visual impact on their bodies. I couldn't see their expressions, only cold eyes as they went back and forth to the passing crowd. It gives people a great oppressive force.

"A gold coin? Why don't you grab it? Even entering Wucheng only costs twenty silver coins, right?" After Yue Yuan heard the entrance fee that the soldiers who stopped them needed to enter the city, he immediately stopped doing it.

"Hmph, the rules are set from above, please leave if you don't have money, don't stop here, if you want to make trouble. Tell me that you should be killed as an alien spy", the soldiers in front of Huang Yi and the two said murderously.

Just when Yue Yuan was about to say something, Huang Yi stopped him, took out three golden coins from his body, handed them over, and said with a smile: "I'm sorry, he doesn't know the rules." Don't be angry, this is our entrance fee, and a gold coin in many other places, for you to drink tea, you are fortunate."

"Yes, let's go in, friendly reminder, don't make trouble in the city, and besides, apply for a residence certificate as soon as possible, otherwise you will have to pay the fee next time you want to come in", the soldier said in a soothing tone after getting the three gold coins, but with a condescending attitude.

"It must be", Huang Yi said with a smile, and then pulled Yue Yuan towards the door.

After the world entered the end of the world more than ten years ago, the old order collapsed, especially the financial order, it was a mess, these years, the world's major forces united, and gradually restored a certain financial order, because the paper currency was not easy to store in the last days, so all were replaced with metal currency, there are three kinds of metal currency, namely gold, silver and copper three currencies, one hundred copper coins are equal to one silver coin, one silver coin is equal to one gold coin, take a hundred to one exchange ratio.

Depending on the item, the price is also different, a copper coin can be bought in the hands of some merchants a fist-sized, black and I don't know what kind of powder is mixed together, and I can't eat enough and can't eat the dead.

Huang Yi has the economic situation of various cities in this world in his mind, on average, ordinary people at the bottom, working hard every day, may be able to get about twenty to thirty copper coins of income, this is just average, you can imagine how difficult people's lives are.

Thirty copper coins seems like a lot, after all, a black food only costs one copper coin, but don't forget, that kind of thing is not eaten by people at all, and the price of a slightly better one is doubled or even tenfold, if you want to really eat a good meal, such as the meat of a mutant beast, you can't get it without dozens of silver coins.

It can be seen from this that the people of Fort Montenegro are so happy that they have meat to eat every meal, and it is also the meat of mutant beasts.

At this time, Huang Yi and they need to pay a gold coin entrance fee to enter the city, which is simply a huge amount of money, compared to 10,000 copper coins, it is the income of ordinary people at the bottom for a few years, can it not make people feel distressed? It's no wonder that Yue Yuan screamed.

The fact is that if you calculate it carefully, the price of a gold coin is really nothing, after all, life can be guaranteed after entering the city, not from the threat of mutant beasts, compared to life, what is a gold coin? Another point, after entering the city, you can not come out, you can live for a few years or more than ten years and be fine, in this way, a gold coin is definitely not expensive.

"You're stupid, that's a gold coin, no, three gold coins, you actually gave it to the other party"? After entering the door, Yue Yuan looked at Huang Yi and complained, saying that he hadn't saved a single gold coin as a cook for several years.

"Such people, obviously this blackmail us, if they continue to entangle, in other people's territory, it is not good for us, there is a saying that no profit is not early, why do you think they go to the city gate to guard the door like a watchdog? It's not that I fancy this and the fat difference, take the opportunity to make a fortune, those guards on the city wall are envious", Huang Yi said with a smile indifferently.

"Then I can't just give it to them", Yue Yuan couldn't let go.

"Let's go, we're here to explore the way, not to make trouble, although we are very poor now, there is no need to lose points for a small sum of three gold coins", Huang Yi said with a smile.

"Big brother, three gold coins are still a little money? One gold coin can make people live in any city for a year, and still a little money? It's like you're rich," Yue Yuan pouted.

Huang Yi smiled and didn't say anything, can he say that although he has been tortured by Lao Bao in the past few years, there is still revenge for carrying out the mission? Especially Jiang Lin of the Jiang family in the last stupid martial arts city, the reward for that time was three thousand gold!

In any period, the authenticity of the currency is the most important thing to pay attention to, don't think that the currency in the last days is metal currency is easy to fake money, in fact, any currency, there is a microchip, only need to be scanned on a special instrument to identify the authenticity, which is loaded with a simple program, if this kind of program is broken, the top will immediately replace the program, to achieve the purpose that others can not do the price......

After the two entered the carp city, they began to wander aimlessly.

Although the carp city only produces carp, the sparrow is small and complete, and there should be a business model.

There are food shops, weapons shops, pharmacy shops, grocery stores and other necessary shops, but also restaurants, tea houses, hotels, casinos, green buildings and other places for entertainment and relaxation, and even rings, beast fights, martial arts halls, schools and other places.

More than 100,000 people gathered here, each performing its own duties, forming a unique living environment for human beings, although human beings have entered the last days, but after all, they came from the period of civilization, not a primitive society, with wisdom experience, it is not difficult to establish a human survival civilization on the basis of wisdom experience, but just start over again.

After a circle, Huang Yi and Yue Yuan opened their eyes, compared with Liyu City, Black Mountain Fort is simply a primitive society, no finance, no shops, it can be said that there is nothing, people still eat a big pot of rice, go out hunting together and then have food, is it not a primitive society?

"We're almost done, what do we do next"? Yue Yuan asked, squinting his eyes and looking at places like the restaurant in the city from time to time, obviously greedy.

"Let's go to a few grain stores to get in touch with each other to understand the grain market, then sell the grain we brought, and then buy the necessary supplies according to the money we get and go back," Huang Yi said after thinking about it.

Huang Yi himself has some money, but that is his own, not that he is reluctant to use his money for the construction of Montenegro Fort, but he knows that it will not work, Montenegro Fort must develop first, it is unrealistic to rely on individuals alone, only as a whole, the formation of a virtuous circle is the journey, just relying on him alone is a drop in the bucket.

Liyu City is a city, there are all kinds of shops, and there is more than one, Huang Yi has a general understanding of the price of grain, but different places, different prices, and different prices, so it is necessary to understand the market first.

The most important resource in the last days of grain crops, and it is also the most consumed resource, so of course, there are more grain shops in Liyu City than in other industries, there are more than a dozen...... (To be continued.) )
