After the price crashed, he used a low price to buy back the purple black gold he had sold.

Feilong's current thinking is already a rudimentary financial thinking, similar to stock investment experts in the Earth era.

But his thinking is just a prototype, Qin Xuan came from the Earth Era, and his investment concept is thousands of times ahead of him.

Wanting to play this set of price-warping tricks with Qin Xuan, his fat dragon was still a little tender.

When Qin Xuan came to the shop in the dungeon, the price of purple black gold had been warped to 11 silver coins a catty by the Fat Dragon Trading House.

The entrance of the Feilong Commercial Bank was densely packed with people selling goods, but the door of the Mantian Star Commercial Bank was deserted, and there was no shadow of a single person.

Not only did the Mantianxing Commercial Bank have no business, but several shops around it were also deserted because of the price gouging behavior of the Feilong Commercial Bank.

Recently, the price of materials in the dungeon has soared to an outrageous level, almost one price a day, and the workers who are mining basically stop selling their goods in small stalls, and will go to the trading houses to sell them.

Because the prices of large commercial banks are flat, the prices of small stalls are generally lower than those of commercial banks.

Because of the price increase, the stall owners of some small stalls couldn't receive the goods, so they simply collected the stalls in the dungeon and went directly to the city gate to squat to receive the goods.

Many miners are nervous about money, so they basically choose to sell the ore at the gate of the city, and then continue to mine in the mountains, so that they can save a fee for entering the city.

"Immediately increase the price to 12 silver coins!" Qin Xuan said with a glance at Man Tianxing.

Man Tianxing immediately hung the prepared price tag at the entrance of the store.

The 12 silver coins were one silver coin higher than the Fat Dragon Trading Bank, and it immediately attracted a large number of sellers to transfer to the Mantian Star Trading Bank.

But in less than half an hour, Feilong raised the price to 13 silver coins, and the vendors lining up at the door of the Star Trading House all ran to the Feilong Trading House.

Man Tianxing asked, "Boss, should we raise the price again?"

"No need!" Qin Xuan smiled faintly, "It's hanging at this price, if someone comes to sell, we will buy it, and if no one comes to sell it, forget it!"

The price of 12 silver coins, the full sky star firm hung for three days in one breath, although the Feilong firm hung 13 silver coins, but the main purpose of the high price of the flying dragon was to warp the price, he only arranged a window to receive the goods, responsible for the scales, and the clerk who recorded only arranged a total of five people.

The receipt window is too small, resulting in a large number of sellers queuing up to sell, and some hawkers who are in urgent need of money can't stay up, so they will still sell Ziwujin to the Mantianxing Trading House.

Mantianxing Commercial Bank is really receiving, ten receiving windows are in full swing, and there are as many as 100 employees in the commercial bank, and how many goods can be quickly digested.

But as time passed, the Fat Dragon Trading House withstood the price of 13 silver coins and did not fall.

Xingya Commercial Bank, Huangtian Commercial Bank, and Wansheng, Jinfeng, and other four major trading houses have also successively raised the price to 13 silver coins.

There is no way to raise the price, most of the goods have been taken away by the fat dragon, and they can only receive some bits and pieces.

The other four firms collectively rose by 13 silver coins, and Feilong didn't pay much attention to it, Feilong knew that those guys were all falling with the wind, and he was more concerned about Qin Xuan's Starry Sky Firm.

However, the price of the Mantianxing Merchant Bank has always remained at 12 silver coins, and it has not risen a dime, of course, it is true that the Mantianxing Merchant Bank has no business.

After this situation lasted for three days, the Star Merchant House suddenly remade it, directly raising the price of Purple Black Gold from 13 silver coins to 15 silver coins!

Two silver coins were raised at a time, causing a large number of vendors to flock over to sell the pressure, and a long queue formed directly at the entrance of the Starry Sky Trading Bank.

Xingya Commercial Bank, the owner is a beautiful woman in her 30s, her name is Xingya!

She has been living in the manor in the Guangming District for a long time, but in the last few days, the price riot in the dungeon has been very serious, so she came down herself.

Just in time for the crazy price of the Star Merchant Bank, it rose directly from 12 silver coins to 15 silver coins.

The price of the Mantian Star Commercial Bank had just increased, and Xingya got the information as soon as possible, because Xingya Commercial Bank was on the opposite side of the Mantian Star Commercial Bank.

"Boss, that slut from Mantianxing has started to warp the price again, what should we do?"

A girl who looked like a maid in the back asked, "Why don't we just smash all the goods in the warehouse to them, so that this slut can taste it?"

In the warehouse of Xingya Commercial Bank, there are also 1 billion tons of purple black gold ore, although it is not as terrifying as the fat dragon, but it is also not to be underestimated.

"Don't worry!" Xingya shook her head and replied, "Isn't that old guy of Fat Dragon always betting against the stars? Let's see Fat Dragon's performance first!"

"Let them compete with each other, so that we can profit from it!"

"Yes, boss!" the maid replied and ran to the Feilong Firm to monitor.

Sure enough, Xingya is still quite discerning, and after the Star Trading House raised the price and insisted on receiving a large number of goods for an hour, the Fat Dragon Trading House finally came to the movement, and the Fat Dragon directly listed 16 silver coins and another silver coin.

After the price was warped, there was a long queue at the entrance of the Fat Dragon Commercial Bank, but the queue at the entrance of the Mantian Star Commercial Bank did not retreat.

The big guys all know that the Fat Dragon guy is fake, and the price is real, so he went to the Fat Dragon Firm to line up, and he couldn't necessarily sell the goods for a day and a night, so he was in a hurry to use the money or sell it to the Mantianxing Firm, and 15 silver coins were not a lot.

In this way, three days later, the price of purple black gold was stabilized at 16 silver coins a catty by the Fat Dragon Trading Bank, and Xingya and others also followed suit.

Three days later, the stars remade again, directly increasing the price of purple black gold from 16 silver coins to 20 silver coins!

Guangming District Villa Area!

"Immediately take out all the goods and smash them to the Mantian Star Commercial Bank, not a pound left!" Fei Long decisively gave an order.

Heilong also replied ecstatically: "It's the boss, I'll do it!"

"Wait!" When the black dragon walked to the door, he was stopped by the fat dragon again, "You can't throw 7 billion tons of goods to Mantianxing, it will scare her!"

"How do you sell it?" asked the black dragon, puzzled.

The fat dragon leaned into the black dragon's ear and whispered: "Send 2,000 brothers to sell 70 tons of goods in batches, don't let the stars find out about us and smash the plate again, let him eat the food unknowingly!"

"But......" the black dragon replied rather embarrassed, "this is also inappropriate, there are too many people in line, and our people may not be able to sell everything for a whole day!"

"So, we're going to have to be a little strategic!"
