After Li Si made a lot of delicious promises, Linlang easily agreed to settle here, but Li Si paid a lot of price for this, and all the thousands of silver tickets left on his body were fooled by Linlang, which made him feel pain now.

At this time, although it was already night, Li Si did not need to sleep to be energetic after reaching the physical realm, and he had encountered a lot of strange things outside before, and he was also curious at this time, and planned to go to see it for a long time.

After arriving at the square again, Li Si, like other immortal cultivators, walked slowly while checking the items on each stall one by one.

According to what Xuan Kongzi just said, the transactions of these immortal cultivators generally use two methods.

One is the primitive method of bartering, some immortal cultivators hope to exchange things they don't need in exchange for items they urgently need, so these people often set up stalls for several days in a row, and not a single item is successfully traded, which is also a common thing.

The other is a more popular way, using something called "spirit stone" as a transaction currency, buying and selling items among immortal cultivators.

"The spirit stone, as the name suggests, is a kind of corpse full of heaven and earth aura, and the aura it contains is an extremely replenishing thing for qi refiners.

If you absorb the aura in the spirit stone when you meditate and practice, it will make the cultivation speed of the qi refiner amazing, after all, the qi refiner himself absorbs the refining and scattering aura, and the pure aura is next to you, allowing you to absorb and extract it at will, which are two different things.

But the greatest effect of the spirit stone is not here. Its main purpose is to deploy formations and cast spells. The success of a high-level magic circle, and how effective it is, often depends on the effectiveness of the spirit stones it uses, and a good spirit stone can not only ensure the success of the magic circle, but also greatly increase its power.

And the number of spirit stones consumed to cast spells is far higher than the application of the magic circle.

Because the level and effectiveness of a cultivator's ability to cast spells are generally determined by his own mana cultivation, and if he doesn't fight, he may be able to cast super-level spells by himself alone, so the spirit stone has become the best mana amplifier.

If the Qi Refiner can hold a spirit stone in his hand when casting a more powerful spell, the aura in the spirit stone will continue to replenish the aura lost by the caster when casting the spell, which can support the caster to forcibly cast the spell that could not be used in the first place.

Therefore, the spirit stone has become an excellent choice for the qi refiners to fight fiercely and defeat the strong with the weak, and it is also the best tonic for them to immediately restore their original strength after the spiritual power is greatly damaged, which can greatly increase their chances of survival in the battle.

With so many practical and incredible effects of the spirit stone, it naturally makes its value rise all the way

However, with the huge loss of spirit stones, the excessive mining of spirit stones and the increasing number of spirit stone veins, in today's immortal cultivation world, spirit stones have gradually become a precious luxury, the best newspaper station for immortal cultivators, and the unique circulation currency of immortal cultivators, and also jointly determined the detailed division of the turtle brother and grade of spirit stones.

Spirit stones are divided into four levels according to the amount of spiritual power they contain, including low-level spirit stones, middle-level spirit stones, high-level spirit stones, and top-grade spirit stones, and according to the different spiritual power attributes contained in spirit stones, spirit stones can also be divided into five attribute spirit stones of gold, wood, water, fire and earth, in addition to some rare wind spirit stones, thunder spirit stones, and other rare attribute spirit stones.

Although the spirit stone has a lot of effects, in Li Si's opinion, it is useless, and he is a refiner, and he can't absorb the spiritual energy for his own use like a qi refiner.

However, it is rumored that there is also an extremely rare Yuan Spirit Stone, which contains extremely rich Yuan Power and has an infinite effect on body refiners, but there are naturally fewer rare things like this.

The spirit stone is such a good thing, but Li Si doesn't have half of it.

He didn't think he had anything of value on him, so he went out for a walk with an eye-opening mind at the beginning, and he didn't really expect to catch anything good.

But along the way, he really saw a lot of new things.

Not to mention anything else, Li Siyan was greedy when he saw a large pile of yellow rune paper on a shelf somewhere, you must know that Xiao Yubai used those few rune papers to show his magical power to fly to the sky and the earth, and he could even be invisible.

If you get a lot of rune paper, then your strength will definitely increase greatly, and you will have more means of self-protection when you enter the Demon Beast Mountain Range.

You must know that the big man before was obviously also a guy in the flesh realm, and even he didn't dare to enter the Demon Beast Mountain Range alone, so you can imagine how dangerous the Demon Beast Mountain Range was.

Of course, there are a lot of things he wants in addition to the rune paper, such as a few sharp swords placed somewhere, which are definitely very sharp weapons, and it will definitely be enjoyable to practice his lifeless sword technique.

Although he thought so in his heart, Li Si searched all over his body and didn't find anything that could be exchanged.

Finally, he found a thin needle from his ear, it was the poisonous needle that he picked up from Li Hai in Panlong City, I heard that it was a high-grade spiritual weapon, so it was better to exchange it for a lot of spirit stones.

"Huh, what is this?"

Li Si suddenly felt a hard and abrupt thing in his arms, and then took it out, only to see that this thing was the size of an egg, and it was emitting black light all over his body, which was particularly dazzling.

Li Si then remembered that this was the demon tiger demon pill he had gotten, and he couldn't figure out the specific effect of this demon pill for a while, but Li Si didn't dare to act indiscriminately, so he stayed on his body.

"Demon Pill !!"

A cry of surprise came from not far away.

"Demon pill, where is the demon pill?"

"Brother Tai, you sell this demon pill like this?"

In the blink of an eye, several figures walked towards Li Si.

Li Siluo couldn't help but be taken aback, two of them were in the flesh realm, and two of them were masters of the foundation building period.

Li Si was silent on the surface, but he had already made up his mind at this time that he couldn't sell this demon pill, it is estimated that this is a good thing, damn, even if you want to change it, you have to change it at a sky-high price.

And looking at the people opposite, they don't look like guys with no money, but they can talk about it.

"A few Taoist friends don't need to worry, you see that so many of you want to buy, and I can't sell it. Li Si looked at the few people opposite with a serious face, and arched his hand towards them.

A few people on the other side can get this kind of strength, which one is not an old man, at this time, he still doesn't understand that Li Si wants to make more oil and water, so he is waiting for his own bid.

However, this demon pill is indeed of great use to them, and at this time, regardless of Li Si, a profiteer, they all quoted their own prices.

Li Si was secretly surprised when he heard this, he didn't expect that a mere demon pill had been called for two hundred spirit stones in a short period of time, of course, they all referred to low-level spirit stones, but looking at the pile of yellow rune paper before the price was only twenty spirit stones, Li Si knew that he was going to make a lot of money this time.

"I am willing to exchange with Daoist friends for a mid-grade flying sword. ”

As soon as Li Si heard this person's voice, he immediately became interested, and in a blink of an eye, he found that the person who spoke was a horse-faced man, and seeing his painful look, Li Si knew that he had already recovered his book, and he was ready to promise the horse-faced man.

"I'll get a Sumeru storage bag!"

At this moment, a crisp voice came from a distance, and everyone got out of the way one after another, looking at the man who came in surprise.

You must know that this storage bag is worth a lot of money, even the lowest-level storage bag costs at least four hundred spirit stones, this person is willing to do such a price for a mere demon pill, it is really rich.

Li Si also noticed the commotion of everyone at this time, although he didn't know what the storage bag was, but looking at the formation, it must be worth a lot.

When I looked closely, I saw that the speaker was a young man in white clothes, with a wicked smile on the corner of his mouth, and a look of arrogance.

"What, since no one is willing to bid again, then this demon pill should be mine, right?" the young man looked at Li Si and smiled.

"Well, return... It's yours. After speaking, Li Si threw the demon pill in his hand towards the young man, and the other party also threw a bag over at this time.

Li Siyi regretted it as soon as he caught the bag, only to see that this palm-sized bag was paralyzed to death, and there was obviously nothing dry.

Is this damn kidding me?

Li Si lifted the bag and shook it to the ground, signaling everyone to testify for himself, there was indeed nothing in it.

But finding that everyone was looking at him with envy, Li Si was stunned again, could there be any secrets in this bag?

If there is really any secret, he will catch up with the young man now, and he will make people say that he is a dirt bun and does not know the goods, which is a big bad thing, thinking about it, Li Si put away the bag and put it in his arms, turned around and left the crowd.
