The ten elders instantly stared at Lin Mu, waiting for his next move.

I saw Lin Mu wave his hand slightly, and two pieces of top-grade fine iron slowly fell to the original position where the pig iron was released, and the remaining piece of top-grade fine iron returned to the furnace.

Several elders exchanged glances, and they knew in their hearts that Lin Mu was about to start refining.

Lin Mu threw the flame into the furnace again, and then closed his eyes again.

While controlling the flame that burned the refined iron, Lin Mu quickly searched for what he wanted to refine in his mind.

Knives, swords, spears...

Suddenly, a flash of light flashed in Lin Mu's mind, and he remembered the low-grade treasure dagger that he had successfully refined for the first time, although after he used it once, he was swallowed by the many demon clouds that had been occupying the sea and refused to leave.

On the spot, he decided to refine another dagger.

Under the scorching of the ultra-high temperature, the refined iron was completely refined in a short time, and at the same time, Lin Mu had already finished portraying the appearance of the dagger in his mind.

Immediately afterwards, Lin Mu led the aura of heaven and earth to infiltrate into the refined iron little by little, and at the same time poured his own vitality into it.

Waiting until the fine iron glowed with a faint silver light, Lin Mu used his spiritual power to recondense the fine iron little by little, changing it into the shape of a dagger.

"Huh!"

Suddenly, Lin Mu opened his eyes suddenly, his left hand suddenly flipped up, and his index finger and middle finger gently hooked the furnace in the void, and the dagger that had been formed in the furnace suddenly popped out of the furnace.

The dagger, which was in an ultra-high temperature, suddenly came into contact with the cold air, and the dagger, which had been burned red, was suddenly plated with a layer of black.

"Huh!"

In less than a breath, Lin Mu's eyes suddenly sank, his left hand suddenly turned back, and his index finger and middle finger lightly tapped at the dagger in the void, and suddenly the dagger sank into the furnace again.

The flame, which had been waiting in the furnace for a long time, saw the dagger enter the ding, and in an instant, it was wrapped in an instant, forming a burning fireball.

"This..."

All the elders looked at Lin Mu's operation with a blank face, puzzled.

In their tens of thousands of practices and profound theories that are solid in their minds, Lin Mu's operation is no different from death.

Just the moment the freshly formed dagger flew out of the furnace, it was enough to blow up a hundred and eighty times, not to mention that the dagger actually went back again......

The high temperature is cooled by cold air, are you afraid that you are playing with the refiner as a striking iron?

What's the matter, and then find that the iron is not beaten and put it back in the furnace to burn it again, and then beat it again after burning?

But to their surprise, Lin Mu did not fail in this wave of operations.

In their perception, this is absolutely impossible.

Suddenly, several elders exchanged glances in unison.

Then, his gaze returned to Lin Mu's body.

Now, they are really getting more and more unable to see through Lin Mu, and even Lin Mu's refining method, they have never heard of it.

Lin Mu's attention was always focused on the burning flame in the furnace, and at this time, around this flame, there was actually a layer of heaven and earth aura and a layer of vitality wrapped in them.

At this moment, Lin Mu's eyes moved slightly, looking at the demon core next to him that had never moved, his fingers were slightly raised, and the demon core slowly floated to the top of the flame according to what he thought in his heart.

"What is he going to do again?!"

The slightly chubby elder sitting on the far side of the left had already moved to Lin Mu's side at some point, and asked the elder beside him who had also moved from the side suspiciously.

"I don't know. ”

The elder stared at Lin Mu intently and shook his head quickly.

The demon core hovered above the flames for about three breaths, and suddenly, as if losing gravity, it sank into the fireball.

"This..."

Several of the second elder monks were puzzled, and their faces had already begun to distort in confusion.

According to common sense, the demon core should not be embedded until the weapon is formed, so that the weapon is not completely formed, and the demon core is thrown into the fire, isn't he afraid that the demon core will melt due to the burning of the scorching flame?

"Don't make a sound, keep watching. ”

The elder, who was still sitting in the middle, but had also moved forward a little bit, frowned without a trace, and scolded in a deep voice.

Several elders instantly quieted down and continued to watch Lin Mu's next moves.

"Boom..."

However, several elders waited for a long time and didn't wait for Lin Mu's next move, but they did wait for something they were very familiar with—thunderclouds.

It's just that this thundercloud doesn't seem to be the same as the one they often deal with.

"Plop!"

Suddenly, an elder fell from his seat in shock.

"Demon... It's a magic cloud!"

The fallen elder shouted in a trembling voice in shock.

"Bang!"

"Bang!"

"Bang bang bang..."

Immediately afterward, the muffled sound of explosions was heard one after another.

There is no doubt that someone next to him failed to refine the weapon.

But at this moment, all the elders were all focused on Lin Mu.

Lin Mu looked up at this old friend indifferently, and closed his eyes again.

This catastrophe was something that the dagger had to bear alone, and he had no way to help it, so he decisively chose to stand by and watch.

"Boom... Boom..."

A dull thunderclap kept rolling in the demon clouds, and suddenly, the demon clouds thundered.

"Bang!"

Immediately after, a thundercloud two fingers long suddenly came.

However, when this thundercloud hit the fireball, it seemed to hit cotton, and as soon as it touched the fireball, it was dragged into it by force.

This time, the demon cloud was very happy, and after the split, no matter what the result was, he drilled into Lin Mu's sea of knowledge.

However, the demon cloud disappeared, and the thunderbolt that slashed down did not disappear, but rampaged through the fireball.

All the elders stared intently at the fireballs with thunder and lightning all around them, and at this moment, no one spoke out again.

Even the elder who fell to the ground sat on the ground in amazement and watched the fireball in the furnace.

Although they didn't make any sound, in their hearts, they couldn't help but think: "As long as they can survive this thunderstorm, no matter what the thing in the fireball is, it will be an indisputable fact that the grade of this thing is a low-grade holy weapon." ”

The thunder and lightning rampage through the fireball for a moment, and finally, it slowly stopped, and the fireball fell back into calm.

"It's done!"

The elders suddenly stared.

Immediately after, they saw that with a slight wave of Lin Mu's left hand, the flames immediately dispersed.

A dagger shining with cold light, lying quietly in the furnace, the mysterious dagger that had only been seen once during the entire refining period finally appeared in everyone's sight.
