If Ziwujin is not cheap, how can so many people go to live in the dungeon? Everyone has spent tens of billions of dollars to buy a house in Guangming District.

The least valuable thing in the City of Death is the purple black gold ore, and the most valuable material is some consumables.

If you can't eat for three days, even if you are a strong man, you have to be starved into a dead dog, if you starve for five or six days in a row, even if you are the emperor, you have to become a pile of dry bones.

The city of the dead is surrounded by barren mines, and all the necessities of life in the city are transported from the outside world.

There are more than 10 million mouths waiting to be eaten, and the supplies that have been transported in are so limited that no one can afford to consume them.

The snow grain resources controlled by Qin Xuan are sky-high materials in the City of Death, and the price of a pound of snow particles can be sold for 50,000 silver coins, which is more than ten times more expensive than Montenegro City.

Although salt, grain and other materials are valuable, they are not the most valuable, because these things can be stored for a long time, and powerful people can use storage rings to transport a large amount of food and snow particles from the outside world at one time.

So the prices of these things are controllable, and the really uncontrollable materials are fresh vegetables and fruits.

Even if you have a storage ring, you can't keep these things for a long time, and if you want to sell them, you have to move them every day.

It would be nice if it were that easy to send supplies from the outside world to the City of the Dead, but there were bandits everywhere outside, and the convoy couldn't survive.

Qin Xuan went to the most prosperous street to take a look and found that fresh vegetables and fruits were sold at an average price of more than 800,000 yuan.

Basically, only the City Lord's Mansion and a few housekeepers can afford to eat, and ordinary people can't even pick up a rotten vegetable leaf.

"It's really a deformed world!" Seeing this situation, Qin Xuan couldn't help but sigh, "No wonder there is a vegetable plot in Tuopeng's manor, these fruits and vegetables sold on the street are the kind of villa bosses like Tuopeng, and they feel painful to spend money to buy them." ”

System: Instead of sending a large number of people out to mine, the host should stay in the Guangming District and engage in the financial industry!

"Take advantage of the huge capital and let other people work for you, we don't need to go out and risk mining, and we can sit back and enjoy the results!"

Qin Xuan replied with a wry smile, "Do you think it's so easy to transport supplies? We were able to enter the City of Death smoothly this time, mainly because we didn't carry valuable materials, if we carried a large number of valuable materials, even if we had a brigade of 5,000 people, there would be robbers who would dare to intercept it!"

Even if you put your supplies in a storage ring, you won't be able to resist the prying eyes of the strong.

Qin Xuan's 5,000 centaurs look quite scary, but the general level of mechanical warriors is only level 76, and when you meet a boss above level 85 who wants to mess with you, level 76 mechanical warriors are scum, and in the case of a huge level disparity, the number of people is meaningless.

With this little strength in Qin Xuan's hands, he couldn't be invincible at all.

At the same time, the procurement interface of Wanjie Taobao is automatically opened.

System recommendation: Elementary space-time sphere!

"The internal space is 50,000 acres, and the fastest time and space acceleration can be run at the earliest, which is the first choice for cultivating crops and developing pastures!"

This primary space-time sphere, the internal structure principle is somewhat similar to that of the storage ring, and it belongs to the dimensional space that has been cut out.

After entering the inner space through the entrance, there is a new world, and the space inside the space-time sphere is completely built according to the standards of the universe planets, and you can cultivate vegetables, grains, and even pasture farming in the inner space.

The internal time flow rate is seven times that of the outside, and the outside day is 7 days inside, and the crops that originally took 70 days to mature can only be harvested in 10 days when cultivated in the primary space-time sphere.

5,000 acres of farmland can be cultivated to produce a large number of crops.

If Qin Xuan had this thing, it would be equivalent to carrying a farm with him, and he would be able to produce a large amount of fruit and vegetable materials with him, without having to spend energy transporting them from the outside world into the City of Death for sale.

The price of the primary space-time bead is 120,000 units of crystal refining, which is not very expensive.

And this thing can be manufactured by the mechanic, and there is no need to spend money on the finished product at all, just buy some materials.

However, Qin Xuan was not very satisfied with this primary space-time sphere, the cultivated land area in it was too small, and the growth cycle was too slow, which could not meet Qin Xuan's needs at all.

Qin Xuan directly gave up the purchase, and searched for "high-grade space-time beads" in Wanjie Taobao, and sure enough, it was also in stock.

Advanced space-time beads: The internal space is 5000 square kilometers, and the fastest time and space acceleration can be 28 times!

The high-grade space-time bead is already the top commodity of its kind, if you want a more advanced commodity, it is the cosmic bead, which costs 100 trillion units of refining crystals, which is not something that ordinary people can afford.

For Qin Xuan, the high-grade space-time bead was enough.

The area of 5,000 square kilometers is seven times larger than that of the City of the Dead, and if it is all used to grow vegetables, it can feed a large number of people.

High-grade space-time beads, Qin Xuan directly purchased two at one time.

After buying the things, Qin Xuan immediately mobilized the robot warriors to enter the space-time bead to cultivate melons, fruits and vegetables, and prepared to use agriculture to make a fortune.

When the robot was busy developing farmland and growing vegetables, Qin Xuan transformed a few houses in the front yard of his house into shops.

A few days later, Qin Xuan's "instant vegetables" had a bumper harvest, and Qin Xuan asked Man Tianxing to set up a stall in front of his house to sell vegetables.

As a result, more than 10,000 catties of vegetables were snatched up in less than an hour!

On this day, Qin Xuan made a lot of money just by selling vegetables, and he was so happy that he was full of stars, he didn't have to run out and work hard, he could make so much money by setting up a stall and selling vegetables in the safe zone, and while selling vegetables to make money, he could not only earn wages, but also earn aristocratic points to contribute points!

Now, the identity of Man Tianxing is already a one-star nobleman of the Blue Charm Empire.

Qin Xuan would not keep these useless silver coins, and after the silver coins he bought were in hand, there was a full sky star who was responsible for going to the dungeon to buy purple black gold ore cheaply.

Reselling back and forth, Qin Xuan harvested 94 million tons of purple black gold in this day!

Vegetables are the most valuable materials in the City of Death, and purple black gold is the cheapest mineral in this place, which means that Qin Xuan will exchange the most expensive materials for the cheapest materials, and through the conversion of silver coins, the profits in this are unimaginably large.

After a few days of "flipping" like this, Qin Xuan's reselling behavior actually caused the price of goods in the City of Death to be reversed.

Because the amount of purple black gold purchased by Qin Xuan was too huge, most of the purple black gold ore that had been silted up in the dungeon for many years flowed into Qin Xuan's pocket.
