The Xuantian Vine is a spiritual object recorded in the Xuantian Sword Technique, and it is also the main material for refining the twelve Xuantian Flying Swords, and the twelve Xuantian Flying Swords are essential weapons for cultivating the Xuantian Sword Array.

The Xuantian Sword Formation is a kind of sword formation recorded in the Xuantian Sword Technique, which gathers the power of twelve Xuantian flying swords, exerting the strength and combat effectiveness far beyond the cultivator's own realm, killing masters of the same level is like slaughtering chickens and dogs, even if it is facing a master who is one realm higher than it, it has the power of a battle, and it can even be easily killed.

It's just that the refining of the Xuantian Flying Sword is extremely difficult, and the main material Xuantian Vine is even more cherished and difficult to obtain, even the creator of the Xuantian Sword Technique has only obtained some fragments of the Xuantian Vine, and refining a Xuantian Sword Embryo needs to incorporate a large number of cherished materials in order to refine it into the Xuantian Flying Sword, not to mention refining twelve Xuantian Flying Swords to form the Xuantian Sword Array.

Yang Feng asked the deacon of the Adventurer's Guild about the news of the Xuantian Vine, but he only asked casually, without much hope.

"You said that the Xuantian vine should be a 100,000-year-level devil vine, it is an extremely ferocious plant, even the Xuanshi does not dare to provoke it easily, our adventurer's union really does not have a 100,000-year-level devil vine, but even if there is, with the 100,000-year-old year of the devil vine, and its medicinal value, it is far from enough to have 200,000 top-grade Xuanshi."

When Yang Feng finished explaining the characteristics of the Xuantian Vine and his own requirements for the size of the Xuantian Vine, the Deacon of the Adventurer's Guild immediately took out a crystal card with a palm-sized ball from the space ring, flipped his hands over and pointed quickly, and said with a calm face after inquiring about the information of the Xuantian Vine.

"Although the Adventurer's Guild does not have a 100,000-year-old devil vine, it should know the whereabouts of the 100,000-year-old devil vine!"

Hearing the words of the deacon of the Adventurer's Guild, Yang Feng's face showed a hint of joy, and he hurriedly asked.

The Xuantian Vine is of great significance to Yang Feng, it can raise his combat effectiveness to an extremely high level, so that he has an extremely powerful hole card, which is his inevitable thing, no matter how difficult and dangerous, Yang Feng is not afraid.

Hearing Yang Feng's words, seeing the joy on Yang Feng's face, the deacon of the Adventurer's Guild smiled slightly and said: "The devil vine grows in the ninth layer of the catacomb, without the strength of the Xuan Master, it is best not to enter the ninth layer of the catacomb, otherwise it will be the end of nine deaths and one life!" As for the detailed information, you need to spend a million guild points to buy! ”

Hearing the words of the deacon of the Adventurer's Guild, Yang Feng did not hesitate or hesitate at all, and immediately spent one million guild points to buy the details of the Xuantian Vine, and looked at it carefully.

According to the information of the Adventurer's Guild, the ninth layer of the catacombs is full of poisonous gas, if there is no strength of the Xuan Master, and there is no antidote, it is impossible to survive in it, and it only takes a minute to be poisoned by the poisonous gas of the ninth layer of the catacombs, so Yang Feng purchased a batch of antidote from the Adventurer's Guild to deal with the poisonous gas on the ninth layer of the catacomb.

After obtaining the items and information he wanted, Yang Feng went straight to the direction of the Tianxing Auction House, purchased a large number of raw materials such as ores and medicinal materials, and stored them in the Dongtian World.

"Miss, this ore contains a lot of energy, you see, do you Tianxing Auction House accept it?"

"Sir, I know that this kind of ore of yours is an energy ore used to raise demonic beasts, and the value is too low, our Tianxing Auction House does not accept it, you go to the grocery store in Xicheng District that sells all kinds of groceries!"

"The grocery store in Xicheng District, I went to see it, the price they gave was too low, I didn't want to sell it!"

Yang Feng, who was asking the service staff of Tianxing Auction House about the auction in three days, heard the conversation between a charming-looking woman and a middle-aged man in a black tight-fitting battle, and couldn't help but look at the two of them with the rest of his eyes.

I saw that the middle-aged man was holding a fist-sized top-grade spirit stone in his hand, and he begged the charming-looking woman with a look of disgrace, hoping that she could buy the top-grade spirit stone in his hand.

Seeing the top-grade spirit stone in the middle-aged man's hand, Yang Feng's face showed a look of surprise, and he said hello to the waiter beside him, and walked towards the middle-aged man's side.

"Sir, do you have a lot of this energy ore in your hands?"

After carefully looking at the top-grade spirit stone in the middle-aged man's hand, Yang Feng looked at the middle-aged man with a smile on his face and asked.

"Many, much, I found an energy mine outside the city, I thought it was very valuable, so I mined it for half a year, I didn't expect to ask more than a dozen places, but I couldn't sell it at a good price, if you want it, as long as the value is right, I will sell you all this energy ore in my hand."

Hearing Yang Feng's inquiry, a faint smile appeared on the middle-aged man's face, and a pair of expectant eyes looked at Yang Feng tightly and said.

In order to sell the energy ore in his hand, he has visited dozens of stores, but none of them are willing to buy a large number of them at a high price, they all want to buy at a low price, and they are still at a low price that makes him feel a loss.

You must know that in order to mine the energy ore in his hand, he has hired a lot of adventurers and miners, if the price is too low, he will seriously lose money, so when he saw that Yang Feng was interested in the energy ore in his hand, he was already disappointed, and immediately improved a lot, and secretly hoped that Yang Feng could buy the energy ore in his hand at a high price and make a small profit.

"I'm interested in the energy ore in your hand, you can make a price! If the price is right, I can buy all the energy ores in your hands! ”

Hearing the middle-aged man's words, seeing the look of anticipation in his eyes, Yang Feng said with a calm face.

"How about a ton of stone?"

Hearing Yang Feng's words, the middle-aged man pondered for a while, and cautiously quoted a high price.

"Yes, have you brought all the energy ores in your hands?"

Seeing the top-grade spirit stone in the hands of the middle-aged man, it was actually calculated by tons, Yang Feng couldn't help but secretly sigh, the spirit stone in the Great Xuan Realm was so worthless, it was almost the same as picking it up for nothing, and he really made a lot of money.

"Brought, ten tons of energy ore in it."

As soon as Yang Feng's voice fell, the middle-aged man took off the space ring in his hand with a look of ecstasy, handed it to Yang Fengdao, and looked at Yang Feng with excitement and expectation.

One billion tons of energy ore, but he spent all his property, hired dozens of adventurers, hundreds of miners, and continuously mined the results of high-intensity mining for half a year.

You must know that although the cultivation of the adventurers and miners he hired is only at the peak of Jindan, he also has a strong power, and it is extremely normal to mine a billion tons of energy ore in the mine for half a year in a row, if it weren't for the fact that the Xuanshi in his hand was exhausted, maybe he would still continue to mine in the energy mine!

"A billion tons!"

Hearing the middle-aged man's words, Yang Feng was taken aback and involuntarily asked loudly.

"Yes, a billion tons!"

Hearing Yang Feng's words, seeing the look of surprise on Yang Feng's face, the middle-aged man looked at Yang Feng with some bumpiness.

One billion tons, according to the price agreed by the two just now, is one billion Xuanshi, if he can successfully trade, he can not only earn costs, but also make more than 900 million Xuanshi.

After getting the confirmation of the middle-aged man, Yang Feng's face slowly returned to calm, took the space ring he handed over, let go of his divine sense, and scanned it, the space inside was very large, full of top-grade spirit stones, even if it was a lot of spirit marrow.

Seeing the mountains of top-grade spirit stones and massive spirit essence in the space ring, Yang Feng completely understood that in the Great Xuan Realm, the spirit stones, the currency and cultivation resources of the Xuanhuang Great World, were almost the same as the stones on the side of the road, and there were countless of them, and he didn't need to play for ten lifetimes, and he didn't know how to use so many spirit stone resources, how could Zhao Peng, the leader of the Silver Snake Gang, still compete for the undersea spirit stone veins.

In fact, how did Yang Feng know that Zhao Peng's luck was too bad, he came to the Great Xuan Realm a few times, and he wandered around the forest, he didn't meet a single adventurer, let alone discover Tianxing City, but he encountered a lot of demonic beasts, and almost died tragically under the sharp minions of demonic beasts, and he had no chance to obtain the best spirit stones, otherwise how could Zhao Peng not come to the Great Xuan Realm to buy the best spirit stones, but instead go to snatch the undersea spirit stone veins,

Yang Feng transferred the top-grade spirit stones in the space ring in his hand to the cave world, and after transferring a thousand top-grade spirit stones to the space ring, he handed them to the Great Han.

Dahan took the space ring, scanned the thousand top-grade spirit stones inside with his divine sense, his eyes lit up, and he hurriedly thanked Yang Feng, and asked Yang Feng when he continued to buy the top-grade spirit stones, he could reduce the price by three layers and supply it to Yang Feng.

Hearing Dahan's inquiry, Yang Feng hesitated slightly, and then agreed to Dahan to continue to purchase the best spirit stones.

After receiving Yang Feng's affirmative answer, Dahan's face showed a look of ecstasy, and he immediately left the Tianxing Auction House and purchased the best spirit stones in Tianxing City.

In Dahan's opinion, Yang Feng didn't know the price of the best spirit stones, otherwise he would definitely not continue to buy the best spirit stones, he had to hurry up and make a lot of money, once Yang Feng woke up, he wouldn't be able to earn the magic stones.

Seeing that the big man left, Yang Feng smiled slightly, and continued to purchase various raw materials such as ores and medicinal materials.
