"It's kind of interesting." Jiang Zhao sighed.

With such a simple operation, it can greatly simplify the tedious cultivation of the Star Soul stuck behind the five-star.

He could feel that it would be very easy for the Star Soul to absorb the power in the Star Stone.

How so?

Xingshi is like finely processing wheat into big white steamed buns.

And the cultivation method that their group of Nether Star Soul Masters used before was like gnawing wheat, not half a star.

Of course, star stone refining seems simple, but when it comes to real refining, it is not that simple.

Just blending all kinds of star power energy together is not something that ordinary people can do.

And this is still the simplest and lowest-grade star stone, a more advanced star stone, and the internal star power structure will only be more complicated.

It's just that Jiang Zhao doesn't understand one thing.

The Star Soul World has been developed for so many years, and the production of various general-purpose cards can be passed down from the Upper Realm, why hasn't the Star Stone refining method been passed down to the Lower Realm?

Not to mention the card makers of the level of teacher Ao Xian and grandfather.

Any card maker in the association will come out, and with a little exploration and practice, he will have the ability to refine star stones.

In his opinion, even if the upper realm did not pass down the technology, the Star Soul World should be able to develop on its own.

But today's not only has not developed, but is still in the most primitive stage.

With this doubt, Jiang Zhao directly began to try refining.

Relying on the power of Ziwei Emperor, Jiang Zhao was able to extract and separate the star power substances in various card-making materials.

Then, the spiritual power substances with the same attributes and similar properties are aggregated into a mass of star energy matter.

The whole process is effortless and freehand, and there are no difficulties.

It's a pity that at the moment when it finally condensed into crystals, something went wrong.

Bang!

The star-energy matter in front of him collapsed like a failure to make a card.

"Well, it looks like this thing is a bit technical."

Jiang Zhao smiled awkwardly and continued to try.

It's a pity that it still ended in failure.

A series of failures followed.

At the beginning, Jiang Zhao thought that he had not done a good job, and kept summarizing the reasons from his failures.

But no matter how he adjusted, he would eventually fall to the point where he condensed into crystals.

This greatly aroused Jiang Zhao's competitive spirit.

So I began to try to use a variety of different materials, carry out a variety of different proportions and attempts, but unfortunately still ended in failure.

Before you know it, most of the day has passed.

A series of failures made Jiang Zhao's mentality explode, and he even began to doubt himself.

What made him even more incomprehensible was that even according to the recipe of Meng Yunfei's few undead star stones, it would still not succeed if it was 100% reproduced.

"Shouldn't it?"

Jiang Zhao was incredulous, scratching his ears and cheeks.

After struggling for a long time, he let the hadron shuttle through the space and came to the room of the teacher Ao Xian.

After learning Jiang Zhao's confusion, Ao Xian smiled dumbly: "I said why do you look sad, it turns out that this is because of this?" ”

"What do you mean?" Jiang Zhao was confused, "Do you know the reason?" No, you've been exposed to Star Stones too? ”

"Of course," Ao Xian said without thinking: "This is the core resource of the major holy palaces to envelop our nether talents, and when the teacher was young, he was like you, and he tried to refine this thing, not only for the teacher, Jiang Lao and they should have also tried it." ”

Jiang Zhao was stunned: "Does it mean that even you and your grandfather can't refine it?" ”

"Let's tell you this, it's not that we don't have this ability in the Nether, but that we can't make this thing in the Nether Realm at all."

Jiang Zhao was at a loss: "Why?" ”

"Because this thing can only be made with materials produced by the Upper Realm God Domain, and the materials produced by our Lower Realm cannot be condensed into crystals under any circumstances." Ao Xian sighed lightly and explained: "The card makers of the past generations have also been studying the reason, but they have never been able to find the reason, the only thing that can be determined is that the quality of the materials produced by the upper realm is higher, and the star power is stronger than that of the lower realm.

But even if we use the best quality materials in our Nether, on the contrary, as long as they are materials produced in the Upperworld, no matter how bad the quality is, they can be condensed into star stones. ”

Jiang Zhao was stunned for a moment, "Why?" ”

"As a teacher, I also want to figure it out, but unfortunately I don't have that ability." Ao Xian laughed to himself.

From his self-deprecating expression, it is not difficult to see that he must have put a lot of effort into this back then, but finally gave up.

"It means that there is some unknown difference between the materials of the upper realm and our materials of the lower realm?" Jiang Zhao frowned and asked.

"Yes." Ao Xian nodded helplessly, "But to this day, no one has been able to find out what the specific difference is, not only our Nether Realm, but also the card makers of the Upper Realm God Domain have not studied the reason so far." ”

The more Jiang Zhao listened, the more mysterious he felt, and he was a little bit unbelieving.

Immediately, he took out the upper realm materials in the hands of Meng Yunfei and the others on the spot, and started to try again.

After a while, looking at the star stone that had successfully condensed in his hand, the whole person was slapped in the face.

The star stone in his hand is a little rough, but it is indeed a star stone.

It turned out that there was no problem with his ability and technology, it was simply a matter of materials.

But he really couldn't feel any essential difference between the upper realm materials and the lower realm materials.

"Shouldn't it? How so? ”

Jiang Zhao, who did not believe in evil, tried again with nether materials.

One failure, two failures, three failures......

After several successive failures, he tried to use the Upper Realm material instead, and although it also failed, it did go wrong at the last moment of condensation, which was completely different from the situation where the Nether material collapsed when it came up.

At first, Jiang Zhao thought it was a matter of probability, but after several consecutive attempts, he could only reluctantly accept the reality.

Ao Xian saw everything in his eyes, smiled and said nothing.

Back then, like Jiang Zhao, he didn't believe in this evil, but it was useless.

"If you're interested, you can continue to dig deeper, and maybe you can crack the mystery." Ao Xian said with emotion: "Being a teacher is completely giving up anyway. ”

Now, he just wants to study his dragon god realm stars with peace of mind.

As for this unsolved mystery, leave it to the young people to explore.

Jiang Zhao scratched his head incredulously, and instead found his grandfather and cheap uncles, and wanted them to use various black technology instruments to analyze the difference between the upper realm materials and the lower realm materials.

Knowing Jiang Zhao's intention, Jiang Lingtong and Zhang Daniu looked at each other and smiled dumbly.

In their words, they have been studying this matter for many years, and they have also found nothing.

Seeing that Jiang Zhao didn't believe in evil, several people demonstrated it to him on the spot with various instruments, and the test results did not have any special differences except for the difference in quality and star power.

Faced with the results on the screen of the instrument, Jiang Zhao couldn't help but have some doubts about life.

"By the way, grandpa, have you ever tried to make star stones out of heavenly and earthly treasures?" Jiang Zhao asked coldly.

"Of course I tried, the same, unless it is matched with the materials produced by the upper realm, it can't be made at all." Jiang Lingtong shook his head and smiled bitterly: "However, with the star stone made from the heavenly and earthly treasures, the quality and effect can be much better." ”

"Huh?" Jiang Zhao's eyes lit up slightly, and he instantly grasped Hua Dian, "It means that the heavenly and earthly treasures will not affect the final result, but can make the refining result better?" ”

"That's what happened."

Jiang Lingtong nodded slightly, not knowing what Jiang Zhao was excited about.

But seeing Jiang Zhao's expression, he said excitedly: "Then what if you completely abandon the upper realm materials and completely use the heavenly materials and earth treasures to refine the star stone?" ”

You must know that the treasures of heaven and earth are all made of nether materials.

If this idea is feasible, can it bypass the limitations of the upper boundary materials?

Jiang Lingtong, Zhang Daniu and the others were silent for a moment, and then gasped, and their expressions gradually became excited.

Subsequently, a group of people silently got all kinds of natural treasures and began to try.

It's a pity that the final result made them smile bitterly.

Heavenly materials and earth treasures + upper realm materials can indeed make star stones, but they cannot be condensed into star stones simply with heavenly materials and earth treasures.

Although the results were disappointing to everyone, they were not completely fruitless.

As long as a small amount of upper realm materials are added to the heavenly materials and earth treasures, the star stone can be successfully condensed, but as the proportion of upper realm materials decreases, the success rate of star stone condensation will become lower and lower.

"Tut, it's still a young man's brain that is easy to use~!" Zhang Daniu and the others sighed with emotion: "If that's the case, you can try to produce some star stones." ”

"Indeed," Jiang Lingtong's eyes moved slightly, "Go back and talk to Wang Teng's seniors to see if you can exchange a batch of Upper Realm materials." ”

Although the materials of the upper realm are very scarce in the lower realm, they can continue to produce them with heavenly materials and earth treasures.

In other words, in the case of the right proportion, they can already try to produce star stones.

It's just that in terms of cost, it's definitely much higher than the star stones produced by the upper realm.

After all, the cost of heavenly materials and earth treasures is not low, and each heavenly material and earth treasure is synthesized with many nether materials, and it is necessary to use soul power to condense the heavenly materials and earth treasures.

Although Jiang Zhao was a little disappointed, he could understand everyone's happiness.

"Rather than that, it's better to purchase materials directly from the Upper Realm."

In his opinion, the cost of doing so is too high.

But seeing my grandfather and cheap uncles, he shook his head and smiled bitterly: "If it were really that simple, Star Stone would have been popularized in our Nether Realm a long time ago." ”

"What do you mean? Is it difficult to trade between the upper and lower bounds? Jiang Zhao was puzzled: "Just come down to someone, you can put a bunch of them in the storage card, it shouldn't be difficult, right?" ”

"As you said, it's not difficult to send the materials from the upper realm, the key is that the amount of goods that can be sent down at a time is limited." Jiang Lingtong explained.

"Why is that?" Jiang Zhao was puzzled.

Zhang Daniu and the others helplessly explained: "Xingshi is the core resource of the Upper Realm Divine Domain forces to control the Lower Realm, so the Upper Realm has clear review and regulations in this regard.

It's like these upper realm materials in your hand, it's nothing for Wang Teng's predecessors to bring them down by the way, but if you want to bring them down in large quantities, you have to go through layers of approval.

So even if we reach a cooperation with Wang Teng's predecessors, the amount they can send over each time is limited. ”

Jiang Zhao frowned, "If you really want to reach a cooperation, it's not up to them to decide how much to send or how little to send?" ”

"No, no, no, you have to know that the Star Soul World is not only a force on their side of the Northern Night Divine Kingdom, if it is detected by other divine forces, Wang Teng's predecessors will have to bear a lot of responsibility and pressure."

"What if we trade the Star Stone directly?" Jiang Zhao frowned and asked.

"It's the same," Jiang Ling said, "Even if it is their own subordinate Holy Palace, there is a quota for the star stones sent down every time, especially the high-quality star stones, which have to be applied for in advance." ”

Hearing this, Jiang Zhao completely understood.

In the final analysis, it is actually the forces of the Upper Divine Domain that are monopolizing and controlling resources in order to control the lower realm.

And what they said before about talking to Wang Teng's predecessors was only doing business with Wang Teng personally, and the Northern Night Divine Kingdom was most likely disdainful of trading with them.
