The group of ten people regained their quiet, and under Ling Xue's guidance, they walked into the door of another room in front.

As soon as he entered the door, Lin Mu immediately felt that the atmosphere between them immediately became solemn, and directly opposite them, there were ten self-explanatory elders sitting on their faces.

"Hello Elders. ”

Lin Mu bowed respectfully to the ten elders along with the group.

"Hmm. ”

The ten elders nodded without a trace, and they were able to get up.

The moment he got up again, Lin Mu glanced around with his spare eyes, and found that Ling Xue had already left the room and brought the door with him.

"True speed. ”

Lin Mu secretly sighed.

"Tan Qiu, Dongfang You, Nangong Feizhou, Wei Tu, Ji Boshe, An Fang, He Hua, Miao Wo, the nine of you are assessed as a one-star refiner, and you need to refine two medium-grade and above-grade treasures, and the assessment can be successful, and each person has three refining opportunities. ”

The elder sitting in the middle first glanced at everyone with an indifferent expression, and then spoke eloquently.

"Lin Mu, the assessment of the three-star refiner needs to successfully refine two medium-grade holy weapons, or three low-grade holy weapons, and the assessment can be successful, and there are three opportunities to refine the weapons. ”

After a pause, he looked at Lin Mu who was sitting directly opposite him, his expression was still indifferent, but Lin Mu was keenly aware that this elder's gaze had swept over him several times.

Moreover, as the elder said his name, the nine elders sitting next to him looked at him almost synchronously.

"Holy!"

"Assessing a three-star refiner? I heard you right, right?"

"How old does this guy look to be, isn't he even fifteen?"

As soon as the elder's words fell, the nine candidates who came in with him were suddenly startled, and their eyes looked at him like devils, and their mouths did not stop.

"Alright, let's get started. ”

It was still the elder who had just spoken, and the moment he spoke, everyone fell silent again.

As soon as the words fell, everyone immediately recovered from the shock, everyone entered a state of high tension, and their attention became more concentrated.

Lin Mu watched them walk to the furnace prepared for them by the union almost synchronously, and when they released the flames and prepared to show their powers, they slowly and leisurely threw out their furnace tripods from the Sumeru ring.

Under normal circumstances, a refiner will have his own furnace ding, but for those who have just taken the assessment and have not really become a refiner, they usually learn refining tools, and almost all of them use the most common furnace ding with a fair price on the market.

Therefore, considering this situation, when they conduct the assessment, the guild will specially prepare a furnace for them.

Although they were being assessed at the same time, Lin Mu found that the eyes of the ten elders sitting opposite him always seemed to look at him intentionally or unintentionally.

Thinking of this, Lin Mu shook his head and refocused his attention on his furnace.

"Iron!"

The ten elders had been refiners for decades, and their experience was naturally extraordinary, and they recognized it the moment the furnace ding was suspended in front of Lin Mu.

Several elders involuntarily exchanged glances with their companions on the left and right, and they all saw the shock in each other's eyes.

Black iron, known as the hardest iron in the world, is extremely fire-resistant, and it is very rare, and the use of furnaces made of black iron is what a dream for refiners.

This kind of thing that only exists in legends, I didn't expect them to be lucky enough to see it today.

Under the eager gaze of the ten elders, Lin Mu carefully studied the materials prepared for him by the guild.

Dozens of pieces of pig iron, and three pieces of demon cores of shattered realm demon beasts.

Looking at these dozens of pieces of pig iron, Lin Mu thought thoughtfully for a while, and when the other nine people had almost entered the second step, there was a movement in his hand.

I saw Lin Mu wave his hand, and dozens of pieces of pig iron were swept into the furnace by him, and then, under the unknown gaze of the ten elders, he suddenly threw the flames into the furnace.

"This..."

The elders were puzzled and wanted to seek answers from their companions, but when they looked at each other, they found that he was also puzzled.

According to common sense, when refining a refiner, although the amount of pig iron required will vary, not to mention that Lin Mu threw all the more than fifty pieces of pig iron the size of an adult's fist into the furnace in one go, just because the flame is built-in, they can't understand it.

The flame is born under the furnace, which is a basic operation that everyone knows.

But...

Ten people continued to watch the follow-up suspiciously.

But Lin Mu's next operation made them even more confused...

Seeing that a moment after Lin Mu threw the flame into the furnace, they felt that the heaven and earth aura around them began to slowly gather towards the furnace ding inexplicably, and then submerged into the furnace ding.

Immediately after, they saw Lin Mu wave his hand again, and subconsciously, they invariably glanced at the three demon cores next to them.

After confirming that the demon core was still there, several elders breathed a sigh of relief.

But for just a moment, they were all slightly stunned, and then they looked at Lin Mu intently, seeking out what his actions were for just now.

Lin Mu waved his hand, and immediately a steady stream of vitality slowly poured into the furnace.

Then, Lin Mu closed his eyes and began to wait quietly.

One breath...

Two breaths...

Three Breaths...

Four breaths...

Five breaths...

......

Ten breaths...

Suddenly, Lin Mu opened his eyes.

At the same time, the elders suddenly struck a spirit.

In this short ten breaths, they felt that it was so long, and it felt as if half a century had passed.

The elders stared at Lin Mu, who began to move again, only to see Lin Mu's white palm slamming towards the top of the furnace, and three iron balls that flashed with cold light but were only the size of a newborn baby's fist slowly floated out of the furnace.

Seeing these three iron balls that were not at the same level as before, the corners of Lin Mu's mouth rose slightly, and finally showed a smile.

"This is..."

The elders stared at the three extremely small iron balls fiercely, and their eyes froze.

"The best of fine iron!!"

It's... It is the best of fine iron!

Refining holy weapons and even celestial spirit weapons, the best in refined iron is the most ideal existence among all materials, but refined iron is very precious, not to mention the best in fine iron, so when they refine holy weapons, most of them will still use multiple pieces of pig iron instead.

As the so-called level is not enough, the number is to make up.

But even if there is more pig iron, there are a lot of impurities in the holy weapon refined, but if it is refined iron, this situation will be greatly improved, if it is the best in refined iron, then no matter how rough the technique is, the three-star refiner will definitely be able to refine the holy weapon without any impurities. Of course, if it is a very powerful power, it can also use pig iron to refine a holy weapon of 100% purity.

To put it simply, the best in refined iron is actually to remove all the impurities in pig iron, leaving only the most essential part.

It is precisely because of this that the best in fine iron is so hard to find.

At this moment, Lin Mu's hand moved again.
