Inducing the energy concentration, it is indeed easy to select the best material.

But how can this be done by ordinary people?

Fang Xu said lightly and casually, because this was really not a difficult thing for him.

Not to mention the strength of the king's will, just because of his tenth-level high-level spiritual power at the moment, in terms of induction of the quality of refining materials, he is comparable to a great grandmaster-level primordial weapon.

And the average primordial weapon, even if it is a silver level, most of the time, actually judges the quality of the refining material through the observation of the appearance and texture of the refining material, as well as the refining experience.

If you want to sense the energy concentration, you must at least be a grandmaster-level primordial master.

It can be said that although Fang Xu is only a bronze primordial now, his ability in some aspects is almost the same as Zhuang Heng, who is at the peak of gold.

Of course, Zhuang Heng is not clear about this.

After all, the two have only met for a long time, and this kind of internal thing cannot be understood just by observing their appearance.

"Huh?" Seeing Fang Xu put the materials in his hand on an alloy casting refining table, Zhuang Heng suddenly frowned: "Fang Xu, do you really want to use these materials to refine energy blocks?" ”

No wonder Zhuang Heng has doubts.

The formula of the energy block, basically in human civilization, is universal, with fixed specifications and standards.

Because this is a resource that is extremely demanded by human beings, even most of the energy blocks, such as photon energy blocks, are the most common, and they have basically been industrialized and popularized.

In addition, there is also the original energy block, which is very high-end, specially provided for the original weapon, which cannot be refined by ordinary people, and must be mastered by the original weapon.

As the primordial master of the pinnacle of gold, he was very familiar with the refining method of the energy block, and he knew all the more than a dozen formulas that were now circulating by humans with superior effects. He was well aware of many of the recipes that had not been promoted in terms of inefficiency, but which could indeed be refined.

But it was precisely because of his understanding that when he saw the materials selected by Fang Xu, he felt puzzled and puzzled.

The material Fang Xu chose seemed to be a recipe with an inconspicuous reputation, and the efficiency was very low, if he really followed this formula, this would have been able to make the best black iron energy block, and even had a certain chance of achieving the material of the low-grade bronze energy block, but I was afraid that even refining the low-grade and medium-quality black iron energy block would be very reluctant.

"Of course." Regarding Zhuang Heng's question, Fang Xu smiled indifferently and nodded affirmatively.

"Okay, then you can get started." Zhuang Heng frowned, didn't say anything, just waved his hand, but the original sense of expectation in his heart was much lower.

Fang Xu immediately began to make energy blocks.

In this secret room, there is a ready-made plasma smelting furnace, which can directly process the refining materials to the state of semi-finished products, which is convenient for the original craftsman to carry out the last process.

Using this object, Fang Xu quickly finished processing all the materials in his hand, and turned it into a fist-sized cube, crystal clear, like crystal agate, but some of them were not thorough, emitting many distorted halos, which were caused by the energy of various refining materials being smelted together, intermingling and circling, but not fused with each other.

This is actually called an energy block embryo, and it only needs to be put into use in the last process.

But up to this point, the whole manufacturing process is not difficult, only need to master the skilled knowledge, even ordinary people can complete it.

In the latter process, the runes are carved, and various miniature formations are arranged on the embryo to adjust the energy in it, so that it can be perfectly fused, carry out various reactions, and form an autonomous cycle, which is endless, and the pure energy is born, which is the most critical.

This step must be completed by a professional original artist, and cannot be carried out by ordinary people.

Zhuang Heng also raised his spirit a little at this time, observing Fang Xu's movements, because everything that followed could reflect his specific level of Yuan Qi refining.

"Huh? This is ......" Suddenly, Zhuang Heng raised his eyebrows, and with one step, he came to Fang Xu's side, carefully looking at the many runes and formations he had carved on the energy block embryo.

Because he found that the kind of rune formation that Fang Xu was carving at the moment actually gave him a strange and familiar feeling.

It's normal to be familiar with that, there are so many formulas for energy blocks, Zhuang Heng doesn't dare to say that he understands them all, but overall, no matter what kind of formation Fang Xu used to reconcile and derive the energy in it, it was impossible for him not to recognize it.

So when he felt a little strange, Zhuang Heng was also surprised in his heart.

"This, this seems to be the water and fire array in the Five Elements Rune Formation? But it's just that the foundation is similar, and many details have been changed, this kind of rune formation, I really think I've never seen it! ”

The more Zhuang Heng looked at it, the more frightened he became.

Because the miniature formation carved by Fang Xu seemed to be based on the change of the array of water and fire, more than half of the rune arrangements were transformed, but what was amazing was that this change also achieved an excellent effect, which increased the operation efficiency of the entire formation several times, and greatly increased the function of harmonizing and exporting energy.

The so-called array of water and fire, as the name suggests, is only for the use of the energy of the water and fire attributes.

But now this formation revealed in Fang Xu's hand is even more extraordinary, it has transcended the limitations of water and fire, it can be described as yin and yang, not literally, but refers to all the relative energy.

For example, the power of water and fire, the power of yin and yang, and further, there are various corresponding energies in the universe, such as light and darkness, such as positive and negative, positive matter and dark matter, and so on.

The energy contained in the embryo of an energy block is extremely complex, and this is completely a decision of refining materials.

According to the formation, many energy that cannot be reconciled will be repulsed, and the remaining part of the energy will be used to form a cycle, and at the same time, according to many formulas and programs, various energy reactions will be carried out, and a lot of energy will be accumulated.

But in general, the utilization rate of refining materials is only about five or six percent.

This is a technical problem, although everyone knows that a lot of energy is wasted, but with the current level of technical skills, it can only go this far.

What's more, the territory of human civilization spans more than tens of thousands of light years, and the resources are too rich, so there is no need to care too much about these details.

But Zhuang Heng was quite moved at the moment.

Because of this obviously improved formation carved by Fang Xu, the utilization rate of refining energy is extremely high, more than ninety percent.

What's more, he can see that the principle of the change of this formation is not difficult and obscure, just for the formula of energy utilization, consider the layout with a different idea, and the whole effect is completely different.

This means that if you want to promote this new type of energy block formation and corresponding formula, it is not a problem.

This alone can greatly promote the development of grassroots energetics and energy science of mankind.

"This kind of formation, I've never seen it before, could it be that Fang Xu researched it himself? It's incredible......"

This formation used by Fang Xu, although the effect was wonderful, but the principle was not complicated, as the primordial master of the golden peak, Zhuang Heng quickly understood the mystery, and then began to think about the origin of this formation, and many amazing speculations were inevitably born.

"If this is the case, this Fang Xu is definitely an even more genius existence than the two most talented young primordial masters in the empire for hundreds of years, Wen Junyao and Zhong Ziqian! If you can teach this son to become a talent......" Zhuang Heng's mind flashed many thoughts in an instant.

Not only does the apprentice want to worship the Master, but the Master actually wants to take in a genius disciple.

Not only is it easy to teach, but when the apprentice achieves great achievements in the future, the master will also be able to enjoy many honorary crowns.

Of course, as the Primordial Sect Master of the Golden Peak, Zhuang Heng didn't particularly attach great importance to these false names, what he paid more attention to was Fang Xu's qualifications.

Because when he reached the realm of Zhuang Heng, his attainments in the refining of the original weapon were too profound, and he had become a school of his own, so he naturally hoped to pass on his mantle, but this was not a heavy task that ordinary disciples could bear.

However, Zhuang Heng saw this possibility from Fang Xu's body, and his heart would inevitably fluctuate a little.

After many events in the recent period, Fang Xu's overall cultivation has improved, both mentally and physically, he has gained tremendous growth, and making such a simple thing as an energy block is naturally extremely fast, so he quickly completed the last process and successfully refined an energy block.

"Uncle Zhuang? Uncle Zhuang? As soon as he looked up, he saw Zhuang Heng beside him, but strangely found that the latter's eyes were empty, as if he was in a daze.

As soon as Fang Xu shouted like this, Zhuang Heng immediately came back to his senses, and when he saw Fang Xu's strange eyes, he also coughed a little unnaturally, but soon, he didn't have time to take care of these, but asked Fang Xu instead: "The kind of rune formation you used to make the energy block just now, I have never seen it, but it seems to be based on the array of water and fire, is this your own creation?" ”

"It turned out that it was because of the Liangyi Returning Yuan Array." As soon as Fang Xu's heart moved, he understood why Zhuang Heng would be in a daze.

The kind of rune array he used just now is called the Liangyi Guiyuan Array, which still does not exist in the current society, in his memory, this is a genius rune array master decades later, who happened to see the water and fire array on the energy block, and suddenly made an improvement.

Although it was only a few simple changes, it made the entire formation greatly improved, and the efficiency of energy utilization was almost doubled.

This runic array also spread quickly, pushing the manufacturing process of human energy blocks to be further improved.

"Uncle Zhuang, these two Yi Returning Yuan Arrays were not created by me, and I have limited time to contact the refining of the original weapon, how can I create such a formation?" Fang Xu shook his head and said, "This is what my master taught me. ”

"Your master? Could it be the mysterious Grand Master? Zhuang Heng's heart moved, and he immediately remembered the news he had obtained from the Imperial Security Department.

Just as Sima Jie said, when the Imperial Security Department first learned about Fang Xu's recent series of changes, it was also extremely skeptical.

But all suspicions, after Ye Minghui reported a piece of information, they were self-defeating.

The message is simple, but it's powerful.

Fang Xu was accepted as a disciple by a powerhouse who had passed by Lishi Xing.

And this strong man is very likely to be an incomparably powerful Yuan Dan Grand Master.

In this way, the suspicion that Fang Xu's strength was abnormally rapidly increasing could be explained clearly. Since there was a Yuan Dan Grand Grandmaster standing behind him, nothing was impossible.

"Yes." Facing Zhuang Heng's question, Fang Xu nodded.

"I see, it turned out to be a great master, it is not surprising to have such a skill, it seems that your master is also extremely profound in refining weapons." Zhuang Heng sighed.

At the same time, a trace of regret also rose in his heart, he originally thought that Fang Xu had researched it himself, although it was like a fantasy, but if it was true, Fang Xu's refining talent was simply unprecedented, earth-shattering.

However, although the reality is different from what he expected, with Fang Xu's talent, it is also worth his careful guidance, the first is to respond to Liu Zhenting and Ye Minghui's request, and the second is to borrow a good fate to promote the younger generations.
