Qiongwu Star, a suburb of Base City No. 1, a luxury manor villa of the Jiang family.

In the depths of the villa, in a secret room full of Kalu alloy casting, Fang Xu and Qin Lan were looking at the blazing silver-white light in front of them.

There was a circle of thirty-six high-grade silver origin stones on the ground, forming an other formation, and a steady stream of silver origin energy was lifted out, like a trickle, pouring into the air, intertwined, like cobwebs, and finally gathered to form a scorching and burning silver-white light flame.

Around the flame of light, a sphere about one meter in diameter, crystal clear, exuding a crystal-like luster, countless translucent ripples at the edge continued to ripple and spread, and occasionally a white mist popped up, but disappeared in an instant.

Apparently, there was a vacuum sphere around the silver-white flame.

Among them is the purest vacuum realm, even more complete than the vacuum in the universe, because there really is nothing, unlike the universe where there are countless rays and various energies.

In this vacuum sphere, any impurities will be burned by the light flame to break down into basic energy particles in an instant, and then devoured.

The temperature of the silver-white flame must have reached an extremely terrifying level, otherwise it would be impossible to create such a vacuum ball just by the aftermath of the combustion.

But what is amazing is that this terrifying high temperature did not escape in the slightest, and completely converged inside the light flame.

This means that energy is not wasted and is used in the most efficient way.

Karui alloy, although it is an extremely strange alloy, can block the internal energy from leaking, and at the same time has an efficient energy absorption efficiency, which can push the energy absorption from the outside into the interior, but even in the room of Karui alloy casting, it is full of abundant energy, and it is almost impossible to fully use it without waste.

In fact, with modern science and technology, there are still many limitations and deficiencies in the study of energy, and utilization efficiency is one of the problems, which has not been completely solved so far.

The most efficient energy utilization rate for the record is about 60 to 70 percent.

But now, this silver light flame, for the utilization rate of energy, is definitely more than 90%, and infinitely close to 100%, almost completely utilized, no escape loss!

"Fang Xu, what kind of formation is this? I've never seen it before, but it's incredible how efficiently it is to use energy! ”

Qin Lan's face showed a mixture of admiration, shock, and obsession, which was very complicated, a pair of watery black eyes, staring at the operation of the entire rune formation, his eyes flashing with essence, constantly trying to calculate and understand the energy reaction formula in it.

But soon she gave up.

Because the entire formation is integrated and has no flaws, from the outside, it is impossible to see how the energy in it operates and how it reacts.

Subconsciously, Qin Lan turned to Fang Xu, who had laid out this formation.

The two of them are really in the cultivation secret room area of the Jiang family villa at this moment, this secret room is specially used for casting the original weapon, and Jiang Lan specially opened it up in order to facilitate Qin Lan to learn and study the refining of the original weapon, and the whole body is cast by Kalu alloy, and the internal energy concentration is ten times that of the outside world.

Of course, such a secret room, it also cost a lot to arrange, a whole million stars to barely complete, which is an amazing wealth.

After lunch, Jiang Fen contacted the dean of the Qiongwu Academy and learned that the dean was not in the academy at the moment and would not come back in three days.

Immediately, she asked Fang Xu, Ye Jinxuan and the others to wait for three days, and at the same time, she could also take the opportunity to go to the city more, relax and relax, and learn about the many customs of the Qiongwu Star.

Ye Jinxuan readily agreed, and took Fang Ya to play around, but Fang Xu refused on the grounds of exchanging refining experience with Qin Lan.

In fact, he really wanted to have a good exchange with Qin Lan.

First, being able to have a good relationship with the future formation and primordial great master is extremely beneficial to Fang Xu.

Second, his Qingyun Fenggang Wing is a bronze superb original weapon, Fang Xu has basically been completely refined, although it is not the integration of human and weapon, it has also reached the point of being like an arm, this time he met Qin Lan, and it also gave him the idea of upgrading Qingyun Fenggang Wing in his heart.

In fact, Zhuang Heng can also do this, and it is more relaxed.

It's just that when they were on the warp speed battleship, one of them was busy lecturing, the other was busy studying, and there was still cultivation at night, so they didn't have time at all, and Fang Xu didn't think about it, so he delayed.

Originally, he was going to find an opportunity to go to the Firmament Martial Origin Guild and ask Zhuang Heng to help him upgrade, but now that he had met Qin Lan, he didn't have to go through a lot of trouble.

Fang Xu knew very well that Qin Lan, who was only nineteen years old, had reached the lower grade of silver in terms of formation and refining weapons, which was also the reason why she was recognized as a genius girl.

Upgrading the Qingyun Fenggang Wing, a bronze superlative original weapon, was originally extremely difficult, after all, upgrading the old original weapon and refining a new one were completely different concepts.

But Fang Xu has a powerful hole card in his hand, and with Qin Lan's ability, it is completely enough to successfully upgrade Qingyun Fenggang Wing, and he can also use this to get in touch with Qin Lan more, arouse her interest, and deepen his friendship with her, why not?

After all, Qin Lan is not only a genius, but also a little beauty with an attractive temperament, Fang Xu, as a normal man, although the most important thing in his heart is Ye Jinxuan, but being able to get along and talk with beautiful women, especially in a professional field that he is interested in, is also a very happy thing.

Hence the scene in front of us.

Twenty days of study on the warp speed battleship, Fang Xu's basic knowledge of the original weapon is already extremely solid, coupled with his vision of rebirth from the future and many ideas, in Qin Lan's eyes, it seems very amazing, but if you think about it carefully, it is very reasonable, and it often touches her own inspiration.

In this way, the communication between the two was almost a matter of course, and Fang Xu's offer to let Qin Lan help upgrade the original weapon was naturally not a problem.

Especially when he laid out this formation with a terrifying energy utilization rate, Qin Lan became even more interested in Fang Xu.

If Jiang Lan knew what she thought, I am afraid she would be surprised!

From childhood to adulthood, in addition to showing great enthusiasm and interest in formations and refining weapons, Qin Lan was extremely cold to the opposite sex, not to mention chatting for a long time, and even becoming interested.

……………………

……………………

"I call it the Mixed Element Arrogant Light Array." Hearing Qin Lan's inquiry, Fang Xu suddenly woke up from his memories and said.

His gaze swept over the silver-white flame, and in the most central place, in the bright flame, a pair of bronze wings were replaced by Shen Fu, and the cyan brilliance on them slowly faded, and wisps of silver-white luster began to flicker.

After Qin Lan's design, suggestion, and leadership, the power of the Mixed Yuan One Arrogant Light Array was fully brought into play, and the bronze superlative Qingyun Fenggang Wing was slowly but surely evolving towards the silver grade.

"Is the Mixed Yuan an Arrogant Light Array...... It's a name for the occasion, and it's really a mixed element, and it's hard to peek into the secrets. Qin Lan nodded, her eyes flashing with excitement.

After the initial shock and surprise disappeared, she immediately realized what a great invention this formation was, and what a huge impact it would have on the Primordial Realm.

Since ancient times, what has bothered the primordial master the most is actually the most important rune formation when completing the entire refining process.

Especially in the area of energy utilization, the reason why many primordial artifacts cannot be refined by low-level primordial masters is not because of how difficult and obscure their principles are, but because of their ability to use rune formations, the energy utilization rate is not enough, the instantaneous energy supply cannot reach the standard, and the refining materials cannot be fully refined, purified and fused.

This Hybrid Element One Arrogant Light Array has simply solved this problem perfectly, and if it can be implemented, the system of the entire Primordial Realm will undergo major changes!

All primordial masters can refine more high-level primordial weapons, and many of the cost, which is cumbersome and energy-intensive, will also be greatly reduced!

What's more, the method of improving energy utilization contained in this formation, once applied to the original weapon itself, will make the power of the original weapon also gain an incomparably huge increase!

Qin Lan's eyes lit up, her eyes were full of excitement, and on her snow-white face, two blushes rose because of excitement, with her indifferent contradictory temperament, beautiful little face, and the whole person exuded an incomparably charming charm.

Fang Xu inadvertently saw this scene, and the whole person was also slightly stunned, but he quickly came back to his senses.

Not only serious working men are the most attractive, serious women, no! Girls, too, are extremely attractive!

With a word of admiration in his heart, Fang Xu said: "Qin Lan, if you want to learn, I can teach you this Mixed Yuan One Arrogant Light Array, and it should be regarded as your reward for helping me upgrade the original weapon!" It's a great honor to be able to invite the genius formation and the original weapon girl to help upgrade the original weapon! ”

"Are you really willing to teach me? No, no, how can such a precious formation be taught to outsiders casually? Your teacher will definitely not agree, and I am Xuan'er's cousin, you are Xuan'er's good friend, I just helped you upgrade the original weapon, and the most important energy formation is still arranged by yourself, how can I ask for payment? No, it doesn't. ”

Qin Lan was stunned for a moment, a trace of excitement flashed in her eyes at first, but it quickly dimmed, and she shook her head and said, her tone could not hide her disappointment.

Yes, such a precious formation must have been taught to him by Fang Xu's teacher, and it was definitely not allowed to be passed on casually.

When she thought of Fang Xu's mention that her original teacher was Zhuang Heng, she suddenly didn't have too many surprises and doubts in her heart.

As the Great Elder of the Firmament Star Primordial Artifact Guild and a well-known Golden Peak Primordial Master in the Empire, it was not impossible for him to make a breakthrough and create such an epoch-making formation.

After all, inspiration is a very mysterious thing, sometimes there is no matter what, but once it comes, it can't be stopped, and it can often make people do many amazing things.

"It doesn't matter, I made up this formation myself, and I have no connection with the teacher, I can teach it to whoever I want."

Seeing the strong desire in the girl's eyes and the helplessness that she suppressed herself, Fang Xu suddenly smiled dumbly, shook his head and said.

"No, Grandmaster Zhuang Heng is a very kind elder, and his refining attainments are extremely amazing, if you can learn refining from him, you must respect him, how can you just ...... Wait a minute? What did you just say? ”

Qin Lan didn't hear clearly at first, thinking that Fang Xu was going to insist on teaching her formation, so she immediately persuaded her, but halfway through speaking, she suddenly realized that something was wrong.

It seems like...... Seem...... Fang Xu said that this formation was created by himself?

But...... But how is this possible?!

How old is he? He's just a bronze master! Although it is an extremely amazing and remarkable achievement for his peers at this age, it ...... But it shouldn't be possible to create such an amazing formation!

This, how is this possible?

Qin Lan looked at Fang Xu in shock, her little face was full of sluggishness, a pair of bright black eyes, she had lost her agility at the moment, she was full of confusion and disbelief, and she was a little confused, she couldn't believe everything she had heard.
