Bartering can be said to be the most primitive way of trading for humans.

Its advantages and disadvantages are extremely obvious.

For Wang Ping, this trading method is extremely unfriendly.

Although he also has many precious spiritual objects in his hand, no matter how precious spiritual objects are, it is unlikely that he can exchange for the rare spiritual elixir of "Based Building Pill".

Although he has not seen anyone bringing out a spiritual object that can assist in building the foundation.

After walking around like this and remembering the treasures and needs placed in front of each stall, Wang Ping specially selected those who bought spiritual objects and started talking.

Most of the people who bought spiritual objects were spiritual medicines. The spiritual elixirs were not spiritual elixirs on Wang Ping, but there were many spiritual medicines that were hundreds of years old.

At this time, he also took out four or five spiritual medicines that were between three hundred and seven hundred years old, and negotiated several transactions.

Maybe the monks in the Foundation Establishment Stage don’t lack spirit stones, or it is difficult for them to buy treasures suitable for their own use with spirit stones.

Among these transactions, the spirit stones that Wang Ping earned were 20% or 30% more than the spirit stones he could get by selling the spirit medicine to those stores.

What satisfied him the most was that during these transactions, the monks in the Foundation Establishment Stage did not ask about the origin of these spiritual medicines, nor did they try to explore his identity.

This is what he cares about the most and is satisfied with.

Because the underground market will last for several days and other monks will continue to come in, Wang Ping did not rush to take out the things to set up a stall for sale immediately.

Instead, he followed suit and placed a wooden sign with the words "Acquiring auxiliary foundation-building spirits" in front of him, waiting for the monk with relevant spirits in his hand to come and trade with him.

He was not the first to do this. In fact, almost all the Qi Refining Cultivators in the underground market wrote such a wooden sign in front of him like him.

For those of the Qi Refining Cultivator, no treasure is available now, which is of great importance to the spiritual objects that assist in building foundations.

Time passes slowly, and the second day is coming in a blink of an eye.

On the second day, Wang Ping, who had been left alone, finally came up to talk to him as a man wearing a shark-faced mask entered the underground market.

"I have a sap essence taken from the Millennium Blue Blood Tree. How many spirit stones can you produce?"

A low voice came from the man with a shark-faced mask, which made Wang Ping's eyes lit up.

The essence of the sap of the Thousand-year Blue Blood Tree is exactly the same as the "Ten Thousand-Year Spirit Stalactite" in his hands.

After he quickly thought about it in his heart, he immediately looked at the man with a masked shark face and said, "If the senior is really willing to take action on this thing, I am willing to exchange 1,500 low-grade spirit stones, or a 600-year-old blue water ginseng in exchange!"

The price of anything is not constant, but will change according to different places and different groups of people.

Just like the essence of the sap of the thousand-year-old blue blood tree, maybe sometimes you can buy 1,200 low-grade spirit stones, and sometimes you can't buy 1,700 low-grade spirit stones, because it does not belong to the ordinary spiritual creature with oversupply or equal to demand.

Similarly, the same is true for the 600-year-old blue water ginseng.

Wang Ping knew that if he only used spirit stones to trade, he would definitely try his best to sell things at a high price when the other party knew that he was on a weak demand side.

So he followed the trend and made the other party sell it in the opposite way, which made the other party seduced by the 600-year-old blue water ginseng in his hands, making it difficult for him to give up on himself and seek other people's transactions.

Now he already knows how fierce the demand for this kind of high-year spiritual medicine in the foundation-building stage cultivator is, and he knows very well how valuable the high-year spiritual medicines in his hands can be achieved.

Sure enough, after listening to the two transaction prices raised by Wang Ping, the man with a shark face mask fell into hesitation on the spot.

As a foundation-building cultivator who had lived for hundreds of years, he of course also saw Wang Ping's intention.

But it can be seen that if he did not have the same countermeasures as Wang Ping, it would be difficult to make any profit.

He can't speak loudly, just say that he wants both!

After hesitating for a while, he said in a deep voice: "Two thousand low-grade spirit stones, you can take out so many spirit stones, this thousand-year-old blue blood tree sap is yours!"

He actually chose the spirit stone!

Wang Ping looked at the man with a shark face mask in surprise, and was really surprised by this choice.

It should be known that for the foundation-building cultivators, as long as they are willing to spend some time and energy, it is almost not difficult to earn two or three thousand low-grade spirit stones within a few years.

But the elixir of 600-year-old blue water ginseng is different. If you want to get this kind of elixir of age, sometimes you are willing to spend two or three thousand low-grade spirit stones to purchase at a high price, but it may not be possible to acquire it quickly.

What is the reason that it gave up the obviously more cost-effective spiritual medicine and chose the spirit stone?

Wang Ping's thoughts moved and he had a little guess.

After pondering for a while, he nodded and said, "Although the price of senior is a little higher, I know the reason why things are rare is expensive, so let's do as the senior said."

After saying that, he looked at the essence of the tree sap taken out by the man with a shark face mask, and after confirming that it was the same as the records he had read in the classics, he handed over the spirit stone to the other party.

After this transaction, Wang Ping looked at the back of the man with a shark-faced mask and thought about it for a while, and a shimmer flashed in his eyes, and suddenly a bold decision was made.

He reached out and slapped several storage bags around his waist, and took out more than a dozen things and placed them in front of him.

Silver scale iron wood, the eyes of the Ice Toad of Phantom, the "Goglyph" with an age of 800 years...

At this moment, what Wang Ping took out directly overshadowed the limelight of most foundation-building cultivators in the underground market.

Looking at the pile of rare spiritual objects suddenly placed in front of him, many monks in the Foundation Establishment stage showed a look of surprise and doubt in their eyes.

For a moment, he looked at those rare creatures, but he did not look at Wang Ping.

Can a cultivator in the Qi Refining Stage really bring out so many spiritual objects that even a cultivator in the Foundation Establishment Stage is very moved?

Few of the monks present in the Foundation Establishment Stage were willing to believe this.

Especially after recognizing the pair of Phantom Ice Toad's eyes, they were even more convinced of their judgment.

This guy wearing a wolf-faced mask definitely has hidden his cultivation!

If it weren't for the rules of the underground market, they would have released their spiritual sense to press against Wang Ping, forcing him to reveal his true cultivation.

What a sinister guy!

Some monks looked at the wolf-faced mask on Wang Ping's face and instantly labeled him with a sinister label in their hearts.

Of course, this did not prevent them from being attracted by the things Wang Ping took out and came to ask about the price.

Wang Ping only has two types of spiritual objects or spirit stones that assist in foundation building.

He rejected all the rest of the exchange of magic tools and magic talismans.

In this way, after three days, Wang Ping was really replaced by an auxiliary foundation-building spirit called "Fragrant Jade Paste".

Since then, he has four auxiliary foundation-building spirit objects, namely "foundation pill", "ten thousand-year-old spiritual stalactites", "thousand-year-old blue blood tree sap essence", and "scented jade paste".

At the same time, the spirit stones in his hand also exceeded 15,000 low-grade spirit stones in one fell swoop after trading one spiritual object!

On the fifth day of the underground market, a monk wearing a dragon mask suddenly released a powerful aura, attracting everyone's eyes.

"Dear fellow Taoists, please ask. Today is the last trading day of this underground market and the day of the bidding party."

"Next, a certain family will take out the twenty treasures prepared this time one by one. If you have any items you value, you can bid at a higher price. If you lack spiritual stones on your body, you can also deduct other treasures. A certain family will give a fair price according to the market price!"

In the underground cave, the dragon masked monk raised his hands and bowed slightly to everyone who looked at him, and said an exciting news in a deep voice.

Bidding Club is the most attractive place in the underground dark market. No treasure that can appear on the underground dark market bidding Club will be worth less than a thousand lower-grade spirit stones.

But except for the organizers of the underground market, no one knows which underground market will have a bidding event.

At this time, the monks of Dragon Mask suddenly said that there will be a bidding event today, so how can they not make the monks who hear this happy?

Wang Ping was also very happy, and while he was happy, he said in his heart, "It's true."

Previously, when he was trading the "Thousand-year Blue Blood Tree Sap Essence" with the monk wearing a shark mask, he saw that the other party would rather have a spirit stone than a six hundred-year blue water ginseng, he vaguely guessed that the other party was coming for a bidding party.

So he decided to take a gamble at that time and changed his mind and took out various spiritual objects in his hand for spirit stones.

Now it seems that he is undoubtedly gambled right.

At this time, after the dragon mask monk announced the news of the bidding meeting, two monks wearing the same dragon mask soon walked to him.

The three of them sat down behind a stone table. The dragon mask monk who appeared first reached out and slapped a storage bag on his waist and took out the first bidding item.

"The top-level magic weapon Ice Soul Cold Light Needle is made of the master of the refining machine using rare ice-attribute materials, Thousand-year-old cold iron and the third-level ice-mounted monster Ice Crystal Scorpion. When activated, it is invisible and can break most shields and shields, and is actually a powerful weapon for sneak attacks and assassination!"

A nearly transparent flying needle was clamped by the dragon mask monk's fingers and displayed in the eyes of many monks in the cave. The magic power in his hand surged slightly, and the flying needle instantly turned into an invisible cold light and flew out, sank into the stone wall at the top of the cave.

During this process, even if everyone stared at the flying needle, the person who could truly see its trajectory with the power of the naked eye could not find a number of people at the scene.

Such supernatural powers are really shocking!

Just when everyone was shocked by the power of this object, the dragon mask monk had already recalled the flying needle back in his hand, then shook the flying needle between his fingers and said: "The starting price of this object is 5,000 low-grade spirit stones, and each increase is no less than 100 low-grade spirit stones. Now all fellow Taoists can bid!"

"Five thousand and five hundred low-grade spirit stones."

Almost as soon as the monk's words of the dragon mask fell, a male cultivator wearing a deer-faced mask immediately shouted.

But his offer was not competitive at all, and it was soon far exceeded by other monks.

"Seven thousand and six hundred low-grade spirit stones."

"Eight thousand one hundred low-grade spirit stones."

"I will produce nine thousand three hundred low-grade spirit stones!"

One high price after another that made Wang Ping feel frightened, so he easily reported it from each foundation-building monk.

Generally speaking, an ordinary top-level magic weapon is worth four or five thousand low-grade spirit stones.

At this price, it is enough to buy two ordinary top-level magic weapons.

"Ten thousand low-grade spirit stones!"
