attack city

After leaving the forest, there is a prairie. There is another cold wave. The temperature drops to more than 20 degrees below zero. There is heavy snow on the grassland. It is too dangerous to go out and there is no way to hunt. Shenlong City has to continue to move forward.

After the cold wave passed, they solved the problem of food rations.

Six days later, more than a dozen light spots appeared on the radar, almost all concentrated in a small area, with only two on the periphery of that small area.

The closer Shenlong City got to that small area, the more light spots appeared on the radar screen, quickly reaching nearly fifty.

Half an hour later, a huge intersection appeared ahead. Xiang Yang directed Shenlong City to pass through the intersection. The place that came out was a huge valley. You could see the sea in the distance, and you could even feel the air when you stood outside.

of moist water vapor.

This valley is located on the seaside, hundreds of kilometers long and more than ten kilometers wide. One side is close to a beach, one side leads to the plain, and the other two sides are surrounded by mountains and there are only a few roads.

Shenlong City comes from a canyon corridor in the mountains.

"What a big city."

On the observation deck, Gao Hongzhan exclaimed and immediately reported to Xiang Yang: "We found a giant city in the distance, with a height of more than fifty meters. It's only as high as it is."

"Ah, there is another one on the left, higher than the one just now, no, two, no, five, many, many..." Gao Hongzhan was a little panicked. He was frightened by so many super mega cities.

.

In his original impression, Shenlong City was already very big, the largest city he had seen before.

Now there are actually so many bigger ones than Shenlong City.

Moreover, those cities are so huge that their area is even more difficult to estimate.

"This is a trading place, we are lucky."

Bai Qianxue came out. As the captain, she could also hear this channel, so she explained it to Xiang Yang and Gao Hongzhan.

But she didn't know that Xiang Yang came here specially.

Of course, the light spots displayed on the radar screen are all cities.

Before, Xiang Yang didn't tell them where he was going because he couldn't explain why he knew there was a wasteland trading ground here.

The valley where it is now is called Crocodile Valley, and it is also known as the Crocodile Valley Trading Ground.

This is not to say that all one-on-one transactions in the wild and sparsely populated areas are unsafe.

But the wasteland world is, after all, a place where order has collapsed, the environment is harsh, and cruel. The probability of unsafe transactions occurring is much higher than in most normal worlds.

Therefore, the trading market was born.

Because there are a large number of cities gathered in the trading field, when all cities have the need for safe transactions, a mutual supervision mechanism will be formed.

And those cities that are arrogant or have bad motives have become a minority. No one wants to be targeted by the majority, and people with evil thoughts will give up those thoughts.

After all, if there is an unsafe situation, the number of cities willing to trade here will definitely decrease, and over time, a trading place will inevitably collapse.

Those cities that want trading venues to exist will definitely take action.

It doesn't pay to make people angry and get killed.

Another reason why the trading market can maintain its long-term existence is that you can exchange for things you lack in the trading market, and fresh water must be easily available in the surrounding area.

Water resources are very important.

There are many large streams in the mountains here, and there are several natural lakes in the valleys. It is easy to replenish fresh water for cities on land and in the air.

Maritime cities can not only obtain water resources from downstream streams, but also directly replenish seawater. For maritime cities, there are relatively efficient seawater desalination systems.

Therefore, many cities, especially low-level cities, will center their activities around one or several trading venues.

This is relatively safer.

This security is not a matter of being attacked by other cities, but that supplies are easier.

If you really lack resources, you can also stay within the trading area and slowly grow food. You can basically exchange for some other materials in a year and a half.

Growing food requires very high water resources, so the trading farm is an ideal place.

In the wasteland world, food is relatively expensive, but seeds are not. Although growing food for sale is extremely time-consuming, it is a relatively safe way.

There are many such trading places in the wasteland world, spread across various places, and they are basically formed spontaneously.

Some will exist for a long time, but some are difficult to exist for a long time. There are various reasons for their disappearance, not only natural disasters or wild crises, but of course also due to the increase in non-compliance with the rules in the cities involved in the transaction.

After all, the world is complex, any situation may occur, and it is not impossible for mutual supervision mechanisms to fail.

Of course, Xiang Yang had also heard that some trading venues have super cities to maintain order, which are the third stage cities.

Those trading venues even have various rules and regulations, and have the most basic order. They are safer than those formed spontaneously, and their average existence time is longer.

But he has never seen it.

The canyon that came out was relatively far from the seaside, and there were not many cities nearby, so Shenlong City continued to move forward until it reached a place near the seaside, and Xiang Yang stopped Shenlong City.

Then, the radio communication channel was entered.

There are only a few calls in it, and they are all cities in the first stage. The biggest needs are food and various metals, similar to Shenlong City.

In the second stage, there will be a bulletin board function, which can keep records on it for a period of time or erase them in advance, so direct calls will not be necessary in the second stage.

But all cities will pay attention to instant calls. For cities in the first stage, it is just a passive point.

Xiang Yang also began to report the supplies he needed and the supplies he used to exchange. The most important thing was of course food, which was what was needed most at the moment.

The only thing used for exchange is energy blocks. Currently, this is the only one, and it is also the most common exchange item. Almost no one will not want it.

As for melons, purple apple seeds, wild sweet potatoes, etc., they can only be regarded as cash crops. The price is high, but there are few people in demand. Selling these things takes a long time, let alone exchanging food.

Therefore, Xiang Yang called once, and two consecutive cities contacted him, one was Shahe City and the other was Western Forest City.

Xiang Yang established separate communication channels.

"We can sell a lot of grain here, mainly rice, but also flour. The price is the same. How much do you want?" According to the information from Western Forest City, the city owner is a man, or in other words, the person on the call is a man.

Because this kind of trading power can also be transferred, but it is not an ordinary city citizen, but a city's trade minister, which is a managerial position.

The yield of rice per unit time is greater than that of wheat, but the energy consumption and fertilizer costs are much greater, so in summary, the two prices are usually about the same.
