Now, the problem has arisen, after hundreds of years of mining, the reserves of black crystals have dropped significantly, and Kirtland experts predict that the remaining reserves can only be used for another year, after which the black crystals will disappear completely.

At that time, the whole world will be locked in a war for resources, and now, there are signs of that.

The era of peace is coming to an end, and before long, the world will fall into a great war, and then it will be time to compete in strength and heritage.

The black market in the floating city is far away from Yueyu's residence, and it's still too late to rush over, and when the black market opens, it's at night, because at night, the secrecy will be higher, and it's easier to hide.

People who trade on the black market don't want to reveal their identities, so night is the most suitable place, in this world, the temperature at night is very low, fortunately, Zhou Yun's nano suit has the function of this temperature, otherwise, his body can't bear it at all.

This time, Yueyu is driving an anti-gravity sports car, and for the research of anti-gravity, the Moon Butterfly Clan has reached a very deep level, otherwise, it would be impossible to build this magnificent floating giant city.

A few hours later, Yueyu drove an anti-gravity sports car to a nondescript building, and walked in with ease.

Seeing this situation, Zhou Yun was not surprised, on the sports car, the other party introduced his profession to him, it turned out that Yueyu was an existence similar to a mercenary, sometimes, the military would release some tasks for some citizens to complete, and after completion, they would get rich rewards.

Even if there are some more difficult tasks, there are some people who are full of confidence, just like Yueyu's mission this time, he really doesn't know what to say, whether it means that the other party is bold, or he doesn't know whether he is alive or dead.

If she hadn't met him this time, Yueyu might not have come back this time, the reward was valuable, and the price of life was even higher.

With the other party's character, he is really speechless.

followed Yueyu into this very ordinary hut, he didn't find anything abnormal, so he woke up Ryuki to scan and model, and finally found a different place, it turned out that there was another mystery in the wall in front of him, and it needed to be verified to pass.

Obviously, Yueyu was a regular customer here, and following the other party, a staircase extending down, and after walking for a while, she came to a strange place.

Depending on the situation, this place should be underground.

Walking through a door of light, he found that there was a cave inside, and in this kind of place, there were many creatures who were setting up stalls, and they looked strange, and in his eyes, it was simply a gathering of monsters.

Yueyu took Zhou Yun to a registration place, in this place, registration is required to have the right to set up a stall, and when you go to someone else's territory, you naturally have to do things according to other people's rules.

After registration, he has a small card in his hand, which is the secondary school account of the two parties, and after the transaction is successful, the black market will charge a handling fee of one percent, which is similar to the nature of the auction.

However, in the black market, there will be some prohibited items, which is impossible in a regular auction house, and some people who need this kind of thing will naturally return to the black market.

There is white and black in the world, it is impossible to eliminate it, control the black industry within a controllable range, the high-level of the floating city knows the existence of the black market, and they have not cleaned up the black market, which is this kind of thinking, not to mention, the black market can also bring huge benefits to the floating city every year.

Finding the position on the small card, Zhou Yun put all the things out, these things are the most precious things on those flying machines, I believe that many people will be interested in this kind of thing.

Sure enough, it didn't take long for a lot of people to gather in front of his stall, and it seemed that these people knew how extraordinary these things were.

"How many Aquamarine coins do I need for these things? How about 10,000 Aquamarine? ”

Crystal coin is the only currency in this world, black crystal coin, amethyst coin, and blue crystal coin, with an exchange ratio of 1:100, that is, one black crystal coin can be exchanged for one hundred amethyst coins.

There are so many races and many languages here, so everyone has a translator, otherwise they won't understand the other creatures at all.

However, Zhou Yun heard the other party's price, shook his head, and refused directly.

Just kidding, 10,000 aquamarine coins, he understands the price of this world, this aquamarine coins are not enough at all, plus he still needs to buy something, it is impossible to sell it so cheaply.

He knew the true value of these things, and estimated a price in his heart, half a million blue crystal coins, which was his bottom line.

Hearing that Zhou Yun disagreed, the other party left here, seeing this situation, Zhou Yun felt that the other party did not recognize the origin of these things at all, otherwise, how could he say the price of 10,000 blue crystal coins.

Thinking of this, he used a holographic projection and wrote a price of his own bottom line on it, with a minimum of 200,000 azurite coins for each item, a total of five, to prevent some illiterate guys from disturbing him.

Full system projection,He naturally can't use his own,Because his holographic projection is more real,If it is found by someone with a heart,It is inevitable that there will be some trouble,That small card,There is a full system of projection function,Since there is a ready-made,Naturally, you have to use it。

Sure enough, after Zhou Yun gave the lowest price, there were many fewer onlookers, and these people were not sure what was on Zhou Yun's stall, but they just felt extraordinary, so they came here to take a look.

However, obviously there are still people who really know the goods, and soon, he sold two, and the transaction was made at the price of 400,000 blue crystal coins, seeing the other party's expression, Zhou Yun regretted a little, he had already raised the price a little, he felt that the price of 200,000 blue crystal coins was a little low.

After a good start, the next thing is a little deserted, Zhou Yun still has three things left, and the creatures around him don't know the goods, and they all feel that the price is a bit outrageous, only people who really know the goods will feel normal.

The next time, I don't know if his luck ran out, and after an hour, no one cared.

Zhou Yun was a little dumbfounded by this situation, and he still wanted to get rid of these things as soon as possible, and then leave here as soon as possible.

Just when he was thinking about it, the business finally came, Zhou Yun's price, in the eyes of alien creatures who know things, the price is already extremely low, after a good observation, to make sure that there is no problem, the other party will pay the bill, three all-inclusive, 600,000 blue crystal coins in hand.

The total transaction amount was one million blue crystal coins, and after deducting one percent of the handling fee, he still had 990,000 yuan, so he transferred these blue crystal coins to his bearer account.
