Jiang Tian's face was pale.

Neptune's preparations are indeed very thorough, and Master Zhang has also had more than one meticulous deduction.

To him, these are not unexpected, nor are they strange.

Seeing that Jiang Tian was not enjoying the conversation, Master Zhang frowned slightly and could only put the topic away.

Jiang Tian silently stared at the mysterious yellow blood vines that were being sacrificed for the second time.

At this moment, they all turned into "long rope" objects that were several meters long, and looked like neatly trimmed branches.

On their surfaces, there are special spiritual patterns that are mixed with blue and blue.

Boom! The roar started, Jiang Tian looked at the sound, and was immediately attracted.

I saw the golden and silver thunderstones being thrown into the air mass of dozens of feet in the air.

Crackling, booming, booming! A violent roar followed, and the air mass of dozens of meters rose and rolled violently as if it had exploded.

Boom! Abnormal sound! An arm-shaped golden airflow suddenly rushed out, as if to escape from the air mass.

But the next moment, he was forcibly pulled back by a powerful force.

Boom! The abnormal sound resumed, and a golden, silver, and three silver arm-shaped airflow swept out, but it also did not escape the control of the cloud.

In the blink of an eye, he was pulled back by a powerful force.

This situation continued to occur, and the entire cloud seemed to have countless "arms".

Each of them couldn't wait to get out of it, but none of them succeeded.

This situation continued for several days before gradually subsided.

During this period, a large number of gold and silver thunderstones were continuously put into it.

After the subsidence, the mist slowly shrank, and after three days, it shrank to less than half a zhang! Crackling! Rumble! "'Thundercloud paste' is done!"

The Refiner, who was in charge of controlling the air mass, shouted excitedly.

"good!"

Master Zhang nodded and laughed in approval.

This group of "thunder cloud slurry", which was less than half a zhang in size, cost millions of gold and silver thunderstones.

These thunder stones are also not ordinary thunder stones, but some kind of thunder attribute material unique to the sea clan.

Elsewhere, it's hard to come by.

Whoosh! Jiang Tian grabbed the two remaining thunder stones and examined them carefully.

The two thunderstones are one gold and one silver. At first glance, the auras are generally the same, but if you distinguish them carefully, you can find subtle differences.

"This is a male and female thunder stone, the gold stone is the male, and the silver stone is the female. They are extremely ineffective when used alone, and they are not even as good as ordinary thunder materials, but together, they can exert a powerful formidable power, and the effect is amazing!"

Master Zhang said proudly.

"If I guessed correctly, this should be a material unique to the sea clan, right?"

Jiang Tian asked.

"Not bad! This is indeed a unique material of my sea clan, and among the current martial arts forces in the Central Region, only a secret mine controlled by my Sea King Sect is produced!"

Speaking of this, the proud look on Master Zhang's face became even stronger.

Jiang Tian also had to admit that Neptune King Sect did have some unique conditions in the artifact refining.

First of all, their Zongmen station occupies a large area of the sea.

There are many islands in this sea area, surrounded by a large number of aquatic monsters and monsters.

Under the sea and in the deep seabed, there are obviously all kinds of treasures that are hard to find in the outside world.

These thunder stones are one of them.

"Thundercloud slurry and Xuanhuangzhi are both necessary materials for refining 'Yaotu', and they are indispensable!"

With a wave of his right hand, Master Zhang used a small white jade bottle to put away the "Thunder Cloud Paste" for use.

Jiang Tian was noncommittal about this.

Since the refining process took a long time, he had already sat cross-legged in the great formation, refining all kinds of heaven and earth treasures, and silently improving his spiritual power.

It has been almost a month since he came to the Sea King Sect.

Not to mention the treasures of heaven and earth that he has refined himself, the various spiritual powers released in the great formation have also benefited him a lot.

However, Master Zhang seems to have some thoughts on him.

"Jiang Xiaoyou, I see that you have spent most of your time 'concentrating' on your cultivation since you entered the battle, and you are a person who has come here. Spiritual power is not only of little benefit to people in the martial arts like me, but it can even be counterproductive!"

"It's okay, although the spiritual power is complicated, I can handle it myself."

Jiang Tian said lightly.

"Hehe, Jiang Xiaoyou seems to be full of confidence in his talent, but I still want to remind you that there are many geniuses and evildoers in my Sea King Sect, and some of them are not inferior to yours. They were once arranged by the sect master to come to my Item Refining Island to practice cultivation. At the beginning, they had the same idea as you, and they didn't want to miss this rare opportunity, so they absorbed spiritual power, but it turned out that the disadvantages of doing so often outweigh the advantages!"

"for example?"

Jiang Tian looked calm.

Master Zhang was a little disappointed by his response, frowning and said: "I was lucky, I was found and stopped by the old man and other refiners in time, and I didn't go astray, and I was less fortunate, because I secretly absorbed a lot of miscellaneous spirits in a short period of time. It caused the bloodline and spiritual power to be turbulently disordered, the internal breath was irreconcilable, and even paid a heavy price for this, some genius monsters were half-crippled, and the most serious people even nearly died because of it!"

"So that's the case, but I have my own measure, and I don't need Master Zhang to bother. By the way, I won't interfere with the normal refining, please don't worry."

Jiang Tian smiled lightly.

"Okay! The old man has reminded you that if there are any consequences in the future, Jiang Xiaoyou can bear it by yourself, but you must grasp a bottom line, that is, it cannot affect this refining task!"

"I have already promised Sect Master Shui, and I have received your payment. Naturally, I will help you complete the refining of 'Yaotu', so don't worry."

"In this case, the old man has nothing to say."

Master Zhang shook his head and sighed, obviously unhappy.

From his point of view, Jiang Tian is clearly not prioritizing.

But the other party is not a person from this sect, nor his subordinates.

As the other party said, as long as it doesn't affect the normal refining, he really can't interfere.

The refining is still going on, and various materials are constantly being kneaded and refined.

As time passed, the material suspended above the formation became less and less.

After half a month, all the basic materials have been refined, and the total number is roughly in the hundreds! "Report to the master, all the basic materials have been sacrificed!"

More than a dozen refiners finished refining and looked at Master Zhang in unison.

"Very good! Give everyone half a day to rest, but no one is allowed to leave the refining center. After half a day, the refining of 'Yaotu' officially begins!"

"clear!"

More than a dozen refiners retreated one after another.

Some people walked out of the Great Refining Formation, while others sat in the formation to rest and adjust their breath, replenishing the consumed spiritual power.

Master Zhang turned his head and saw that Jiang Tian was still in the formation, with his knees and eyes closed, silently cultivating.
