"Do you want to choose to exchange for a medium-grade spirit stone?"

The middle of the foundation building period, who was in charge of guarding the Treasure Pavilion, was slightly surprised.

Medium-grade spirit stones are not ordinary.

This thing is only produced in some spirit stone veins, and the quantity is much less than that of ordinary low-grade spirit stones.

The amount of spiritual energy contained in a medium-grade spirit stone is about thirty or forty times that of a lower-grade spirit stone.

In addition, the aura in the medium-grade spirit stone is more pure, and the price is naturally higher.

However, this medium-grade spirit stone is generally used during the foundation building period.

Before the foundation building period, few monks used medium-grade spirit stones.

Wang Yuan bowed and said:

"Yes, Uncle Shi, if a disciple wants to refine the formation, he needs to use a medium-grade spirit stone, so if he wants to trade some, according to the rules of the Immortal Dynasty, he can exchange some things. ”

Wang Yuan took out three second-level array disks.

The second-level array disc is already very good.

In the melee over the years, every big battle has to consume a lot of formations, and the refining of the array plate is not much faster, and over the years, the price of the array has increased a lot.

A second-level array disk, it is no problem to sell one thousand three or four spirit stones casually.

The monk of the foundation building period picked up the array plate and looked at it, and nodded with satisfaction:

"This array is not bad, one can trade a thousand spirit stones, but the number of medium-grade spirit stones is very small, this array can trade nine medium-grade spirit stones. What do you think?"

"Thank you, seniors. ”

Wang Yuan did not refuse.

There's no way to suffer a loss.

It's really a medium-grade spirit stone that is too difficult to find.

And that shifting array, the mid-grade spirit stone is a must.

And there are quite a few of them.

After exchanging spirit stones, Wang Yuan inquired about the information of the fourth-order demon pill and the fifth-order demon pill.

Only this time, the expression of the monk in the foundation building period became extremely cold:

"Fourth-order and fifth-order demon pills can be used to refine the elixir of refining spiritual power during the foundation building period, and the demon beast has reached this strength, and even the difference between it and humans is getting smaller and smaller, with your strength, you still don't have to think about it for the time being. ”

Wang Yuan smiled awkwardly and left.

Back in the cave, Wang Yuan continued to cultivate.

Twenty-seven medium-grade spirit stones are a lot, if they are used in a short-distance shifting array, it is enough, but the shifting array is obviously very good, if it is activated? It must require a huge amount of spiritual power.

"Medium-grade spirit stones? Still not enough, so? If you want to urge this shifting array? I can only think of his method. ”

Simply using medium-grade spirit stones, isn't it impossible? But according to Wang Yuan's estimate, it may be at least a thousand.

But it's not a loss.

Medium-grade spirit stones? Used to urge the formation? It's not bad to speed up the speed of condensing the power of the sun and the power of the moon.

Continue to cultivate.

The pills in the storage bag were decreasing at an incomparably terrifying rate, and Wang Yuan's cultivation was becoming more and more stable? The seven layers of the condensation period slowly reached the middle stage.

And with the continuous cultivation of the Pure Yang Earth Yuan Netherworld Water Scroll? Wang Yuan's physical strength and strength reached an unbelievable level, his spiritual power became more and more pure, and his divine soul had also improved significantly.

Flash.

Two months later.

This time Wang Yuan was practicing, and a new prompt appeared:

Everything is a coincidence.

And after the prompt appears, above the formation? A note appeared.

Picking up the transmission note and looking at it, Wang Yuan's brows furrowed slightly:

"At this time, go to explore the Ancient Xiudong Mansion? This foundation-building monk can really find trouble. However, the reward of fifty medium-grade spirit stones is really atmospheric. ”

Isn't this a mandatory task? Wang Yuan subconsciously wanted to refuse.

But remembering the prompt that just appeared, Wang Yuan packed up his things? Get out of the cave.

Out of the cave? Follow the message in the transmission note? Before Wang Yuan came to a cave mansion, dozens of people had already gathered outside this cave mansion.

When they saw Wang Yuan coming, a few people also greeted him.

Wang Yuan returned the salute and chatted together.

"Senior Brother Wang is really an ascetic, he doesn't come out on weekdays, how can he have time to come out this time to explore the Ancient Cultivation Cave Mansion?"

A monk in the late Ning Yuan period spoke, and his attitude was not very good.

Wang Yuan smiled and said:

"In this ancient cultivation cave mansion, it is said that there is a formation and other inheritance, of course I will not miss it. ”

When the other Ning Yuanqi heard this, a smile appeared in his eyes, and he said:

"Wang Daoyou, I heard that you have a formation disk in refining, I don't know if there is any leftover, and my array disk is just a little lacking. ”

This Ning Yuan Period said and took out a jade box.

In the jade box is a second-order topaz spirit rice.

It's only been more than half a year, and Wang Yuan is already well-known in the Five Directions Immortal Vein, and like several other Ning Yuan Stage monks, he is considered to be a person who needs to be befriended in the same rank.

Alchemists, array mages, and refiners are all very rare.

It's good to be able to make friends with one or two.

Wang Yuan was not polite, weighed the jade box, and took out a array plate and gave it to the other party.

A smile appeared on his face at this Ning Yuan Period, and he put away the array plate.

The rest also had a few Ning Yuan period monks come forward and make a deal with Wang Yuan, but Wang Yuan was not polite, and the treasures and pills that were eye-catching were traded, and those who couldn't look down on them directly refused.

After a transaction, other condensation period modifications were more polite.

Even if the battle continues now, the status of the formation mage is still very high.

After waiting for a long time, Jiang Yuhuan in the cave finally walked out.

"You juniors have been waiting for a long time, and I have made a slight breakthrough in this retreat, and I have been delayed for a while. Jiang Yuhuan said with a smile on his face, with a hint of apology on his face.

When the rest of the Ning Yuan Stage monks heard this, they saw Jiang Yuhuan's eyes, but their eyes widened, and their breath was a little thicker.

Wang Yuan's expression was indifferent, his spiritual power was working, and some charming thoughts dissipated in an instant.

"This Jiang family's flattery is really amazing. ”

Jiang Yuhuan led the team, and soon came to a cave in the Five Directions Immortal Vein.

Even if there is a formation around this place, the concentration of aura is extremely amazing, and everyone looks at it, and their eyes are bright.

"Uncle Shi, the disciple has already brought. ”

Jiang Yuhuan came to the outside of the cave mansion and said respectfully.

Call!

The formation above the cave house shone, and in an instant, a black light appeared, and a monk in a black robe appeared in front of everyone.

"Since you're here, let's go. ”

The monk said.

Although he was wearing a black robe and had a black light covering his face, as soon as this voice appeared, an irreparable charm appeared.

All the surrounding Ning Yuan Stages couldn't help but turn their eyes to this black-robed monk.

At this time, in the eyes of many monks, whether it was the black robe or the black qi, not only did not make this female cultivator in the foundation building period lose its charm, but it was a little more mysterious temptation.

"Humph!"

The female cultivator snorted coldly, and a trace of killing intent permeated.

In an instant, the faces of more than a dozen Condenser cultivators turned pale.

The peak coercion of the foundation building period instantly filled the surroundings, who could withstand it.

The black-robed nun didn't speak, and as soon as she stretched out her hand, a flag appeared, floating in the air, and then the black light shone on the flag, and it flew into the sky with sixteen people.

More than ten days later.

Deep in the Valley of the Fallen Dragon, next to an underground river,

The black light dissipated, and Wang Yuan and the others revealed their figures.

On the opposite side of Wang Yuan, a group of people who were attacking a broken formation stopped.
