There was no big news along the way, Su Fan came to this place called Papan City, Papan City is a typical underground city, this underground space does not know how to open up, hemispherical, supported by several extremely thick rock pillars, below is a large number of extremely neatly built buildings, there are also countless buildings hanging on the dome, these buildings are connected by overpasses, the building of the dome and the ground are connected by those extremely thick columns, around the pillars is a circle of spiral roads, in the huge space between the dome and the groundThere are also buildings that hang in the air like fruits, which are connected by drawbridges, and look quite dangerous.

The extremely complex transportation network made Su Fan think of the place Pansi Cave, this Papan City looks like a spider cave, the space in the underground world is very limited, this structure similar to a spider web makes great use of all the space, judging from the situation of the people around them, it is obvious that they have adapted to this kind of life.

The black cloak is obviously universal, Su Fan's standard mysterious person's dress did not attract any special attention in the city, through the observation of this city, Su Fan concluded that this city seems to be a city in the last days! The reason why she has such an idea is from a few points in this city.

The first point is the buildings in Papan City, except for a few buildings in the city center, the surrounding buildings are made of some scrap materials, although they are no different from new materials in terms of strength, but they look tattered on the outside. And the structure of all the buildings is practical and sturdy, the windows of the buildings are small, and they all have iron railings, although the city looks a little dilapidated, but it still seems to be very prosperous, all kinds of shops and bustling people, busy streets, it looks quite prosperous.

In addition to the architectural style, there is also the fact that the city has no currency! It doesn't make sense that such a developed city has no currency, and people are bartered with each other. Hard currency is not absent. It was a yellow-white square of one cubic decimeter, and Su Fan thought it was currency at first, but later she found out that the square was clearly a kind of food! Only in times of extreme food shortages.

Except for this kind of block. There are also people who carry a purple powder on their backs and trade everywhere. The purple powder looked familiar, too far away to discern what it was, but it was certainly a grain of food.

Su Fan walked around the city a few times. After a general observation, she found that the most in the city were shops with all kinds of weapons, short pistol lines and long machine guns were readily available, and they were far more powerful than those she had made in terms of technology, all of them were energy-powered weapons, and the price of these weapons and equipment was very cheap, and almost everyone in the city had guns.

Another thing that caught Su Fan's attention was that all the firearms she saw were different, it seemed that these weapons were all handmade, not standard industrial assembly lines, but these weapons used a kind of spar - maybe a magic crystal, there was no limit to the caliber of bullets.

Su Fan was very interested in these firearms, she searched for them from her storage space, and turned out a bag of rice, now the whole Aurora City is eating this kind of food, this bag of food should have fallen during the teleportation, and it happened to be used now.

"How much does this gun cost?" Su Fan casually came to a weapon shop, pointing to one of the small-caliber rapid-fire guns that looked powerful and domineering.

"Can you afford it?" said the old man, who was polishing something on the workbench with his head down, looked up and said angrily.

"I can't afford it, I'm just asking. Su Fan shrugged his shoulders and left the weapon shop, and heard the old man's sneer behind him.

I went to several weapon shops in a row, and the bosses in those weapon shops were all the bosses of the heavens, and they couldn't see the sky here, so they were the second of the earth bosses, as if they could afford to sell you weapons by selling you, and you had to be grateful to Dai Decai, and even the squinting boss of one family directly said that he would only sell them if he rolled a sheet with him--what is this? Could it be that he has returned to the era of the supply system? But didn't Su Fan see the person who bought the food take out a food stamp or something?

In addition to the weapon shop, the merchants of other shops saw that there were customers who came to serve as diligently as if they had seen their father, and now Su Fan was even more sure of this apocalyptic world, judging from the style of all weapons, they are all handmade, so the weapons in this world are as important as food, and the weapon master who can make weapons is so dragged.

"This young lady, are you looking for a weapon?" Just as Su Fan came out of another weapon shop, a man wearing a black cloak of the same style approached, "I'm from the underground exchange in Papan City, you can call me a grenade." ”

"Yes, the quality of the weapons here alas~" Su Fan pretended to sigh.

"Come to us!" the guy who claimed to be a grenade whispered, and after saying that, he looked around and saw that no one was paying attention to him, so he said in a quieter voice, "Are you interested in a forbidden weapon that has recently come to the underground exchange?"

"Forbidden weapons?" Su Fan didn't know what a forbidden weapon was, so she replied in an ambiguous way.

"300mm howitzers!live weapons!" said the grenade in the smallest voice a human could make.

Su Fan wondered in her heart, the largest artillery she had ever seen was a meter in caliber, how could it be taboo to get here, 300 millimeters? Soon she understood, live ammunition weapons! The weapons she had seen were all magic attacks, without any physical attack ability, either burning or freezing or electricity, there was absolutely no physical attack, this is underground, too large a physical attack may cause a collapse, if it is accurate, a single shot may disappear a city, it is indeed a forbidden weapon.

"If you want to talk about forbidden weapons, I have them here!" Su Fan showed an expression that you understand. However, this grenade is invisible, and both of them are wearing metal masks.

"Oh?" there was a hint of excitement in the voice of the grenade, forbidden weapons are in the hands of the ruling class in various big cities, if it is in the hands of others, it will be eliminated by the top as soon as possible, but if there is a forbidden, it will be sold, this kind of weapon with a powerful physical attack Many rich people like to buy one and hide it, after all, in this dangerous world, in the face of those greedy officials, you must be ready to die with the enemy at any time!

"What is this underground exchange like?" Su Fan began to ask.

"This is the invitation, you can find goodbye by following the address of the invitation" The man called the grenade gave Su Fan a piece of hard paper. Immediately blended into the crowd. Su Fan looked at this piece of hard paper, and didn't know why this guy chose to give this invitation by himself?

No matter what, Su Fan still decided to go to the so-called underground exchange to take a look, maybe there was something worth paying attention to in it. The weapons of this world made a deep impression on her. It's all handmade, though. I don't know if I'll be able to dress up the people of Aurora City by myself.

The map on the invitation showed that the underground exchange did not appear to be in the city, but in a secret cave not far outside the city. I really don't know what the organizers of this secret exchange thought, just sending invitations on the street - or, in the first place, this was a fishing in the first place?

After struggling for a while, Su Fan decided to take a look, anyway, she could retreat back to that black world at any time, and it was a big deal to run away and work directly.

Boom~ There was a sound of something collapsing, Su Fan looked at the source of the sound, it turned out to be the dome, there were several large rocks falling from the dome, these rocks smashed some things on the ground into pieces, and at the same time, a big hole with a diameter of about four meters was exposed on the dome, and some black things were constantly pouring out from this big hole, and if you looked closely, those black things were clearly black monsters! These black monsters began to spread along the dome, and killed those buildings.

"Isn't it" Su Fan hurriedly prepared to run away, why would she be in trouble wherever she came? In the underground world, she couldn't expand her body, and her combat effectiveness dropped sharply, if something happened, it was best to run away.

But when Su Fan saw the appearance of the people around him, he temporarily gave up the idea of escaping, and the people around him were just startled by the rocks falling from the sky, and then they should do something, without the slightest panic, as if this was just a daily routine or rather, this is simply a daily routine

There was no panic in the whole city, some soldiers reacted quickly, first using the magic shield to temporarily plug the big hole dug out by the black monsters, and then began to clear the black monsters that entered the city, the soldiers' reaction speed was very fast, those black monsters did not spread much and were hit by the magic bullets that flew up from the ground, burned to ashes, and some buildings were installed with powerful magic cannons, these weapons are amazingly lethal for the black monsters.

After clearing the surrounding black monsters, a group of magicians came to the big hole dug out by the black monsters, accompanied by bursts of magic fluctuations, the big hole actually healed quickly, and the black monsters inside were also squeezed into flesh, and the hole that was dug out quickly returned to its original state, except for the surrounding fragments of blood and tissue, it was impossible to see that the city was attacked just now.

"What an awesome technique" Su Fan kept his head up and watched the whole process, what kind of magic is this magic? It can regenerate the firmament? Where did the theory of conservation of matter go? Judging from the reactions of the people around him, this kind of thing seems to happen often, and those magicians and warriors dispersed after repairing the big hole in the firmament.

In the next few days, Su Fan wandered around the city idly, she didn't go to the underground exchange, she was going to learn about the city, she also got some of the cube-shaped food that was used as currency, this kind of square is a kind of compressed biscuit, the energy in this compressed biscuit is very high, no wonder it can be used as currency, if such a piece is made into porridge, it can make an adult man not hungry for a week, as for how to make Su Fan doesn't know.

In some small shops in the city, Su Fan used some tree rice to buy some things. It may be that after a long time in the underground world, human beings have mastered a new type of magic, which can detect whether this food can be eaten or not, as long as this magic is swept through various foods, a unit that can be used as currency can be obtained, and the unit of currency in this world is - days, which means that these foods can be eaten by an adult strong man for a day, as for how much this adult strong man can eat, it depends on the mouths of both parties.

Su Fan used about thirty days of food in exchange for some currency, of course, she must have been trapped, a full twenty kilograms of grain. Only thirty days of currency exchanged. She didn't dwell on anything, thirty days can almost be exchanged for a lot of weapons and equipment, the most important thing in this world is metal and other materials, a kilogram of metal can't be exchanged for a kilogram of food at all. As for the purple powder, she figured it out too. It is mushroom powder. No wonder she felt so familiar. Mushrooms do not need light, so they can be grown in large quantities in the dark underground, and ordinary civilians eat mushrooms to survive. As for the real food, because the production is too small, part of it is used as currency, and the other part is eaten by emergency or those rich and handsome.

These people have never heard what is called the ground and what is called the sun, they only know that the light on their heads is called the dome, and the only natural light source is the light emitted by some of the lava that has been dug through the underground lava, and it is not that no one has tried to dig holes up or down, but in the end there is no result, no matter up or down, it seems to be endless rocks.

It seems that human beings appear directly underground, but Su Fan doesn't think so, because human beings have eyes that can sense light, if human beings really evolved from this underground and some underground creatures, then human beings will not have eyes, but human beings in the underground world must use some lighting tools, which shows that human beings have not been in this world for a long time, at least not to the point of evolving their eyes.

"Alas, have you heard, the magma on the Fire Spirit Island has risen again, and the grain production during this time is going to be reduced again" Now Su Fan is sitting in a tavern, drinking the wine made from mushrooms, mushroom powder is not rare in the underground world, but it can be mixed to a full, but the taste is not to mention, but the taste of the wine made from mushroom powder is unique.

"What's going on there?" Su Fan pretended to be unconscious and asked, although this is the underground world, but smart humans have a special planting method, that is, to plant food crops next to some lava rivers, and use the bright plants of lava rivers to photosynthesize, so as to grow, but the light of the lava river cannot be compared with the sun at all, and the surrounding environment is extremely harsh, so the output of food is very small, and it can only be regarded as a luxury that only a few people can eat.

"It's not the city of Goni next to it, they blew up a large part of the upper reaches of the lava river with explosives, I heard that the mayor of Goni and the mayor of Papan City are not dealing with each other, and this action of Goni City is a provocation to Papan City. The man dressed as a merchant said with a sad face, "I have an acre of land there, and now alas"

"Are you a grain merchant?" Su Fan's eyes lit up, and he had a way in his heart, the grain merchant was equivalent to those Shanxi coal bosses in this world, but how could this coal boss drink in such a dilapidated tavern?

"yes, but my land has been swallowed up by the lava river, damn the crumbs of Goni City!" the decadent man took a sip of mushroom wine, "everything I have is crushed on that land!

Looking at the man lying on the bar and crying sadly, there is nothing strange about the people around, because there are many such people in the bar, it is said that because of the rise of the lava river, the underground farms belonging to Papan City have been swallowed up by the lava river, and countless grain merchants have gone bankrupt, although the grain merchants seem to have a lot of money, but once the crops in the land have an accident, then most of the food merchants with a lot of money will go bankrupt immediately, and only those top ones can barely survive.

"Introduce myself, my name is Valkyrie," Su Fan began to prepare for his first step into this world.

"Grolan" The decadent man took a sip of wine fiercely, and said after giving Su Fan a blank look.

"I'm also a grain merchant, and I have about 30,000 days of grain in my hands," Su Fan whispered into Grolan's ear.

After a few days of observation, Su Fan found that the minerals in this world are very cheap, and those various magic materials that can be sold and added in the old world can only be regarded as building materials in this world! Looking at the mythril in those buildings, Su Fan can't wait to demolish the house, although she can also make powerful cannons with ordinary materials, but if a large number of magic materials are used, some high-level weapons, such as electromagnetic cannons or even computers or something, can be realized!

Extract a large amount of food from World One with cheap conventional weapons, part of it for the use of Aurora City, and sell the other part to this world, and then use the food to get a large amount of expensive magic materials and transport it back, the rhythm of a proper plane merchant!
