Su never answered, just got up and walked out.

But when he walked to the front of the door, he was a little unwilling, and looked back at Caixiao and said, "Who told you that the stacked fire seal can't refine flawless materials?"

He didn't care that others doubted his strength, after all, he was reborn for a lifetime, and now he was just a small martial artist, but he still couldn't bear to be looked down on by others.

Because the Stacked Fire Seal was created by him in his previous life, the dignity of being a mad emperor cannot be trampled on.

"But that's the case, the stacked fire seal is only eighty-one heavy, and the limit is a grade A rare material. Caixiao shook her head.

"Eighty-one weighs?"

Su Jue smiled disdainfully, and then took out a piece of red ice again, and then the stacked fire mark appeared.

The fingers of his right hand appeared phantom, and the speed made Caixiao's eyes tremble.

Seventy, seventy-five, eighty, eighty-one......

Caixiao began to get nervous.

Followed by......

Eighty-two.

"This ......"

Caixiao immediately got up and looked at this scene in horror.

There are more than eighty-one stacked fire seals!

However, this is not all, I saw that Su Du's speed became faster again.

Eighty-two, eighty-three, eighty-four......

Up to ninety stacked fire marks.

At this time, Caixiao's small mouth looked like an egg, and she couldn't help but tremble a little, and her brain was even more blank.

A gleam flashed in Su Jie's eyes, and his right hand took over the red ice that had been refined and was only the size of a grain of rice.

At this time, he was shocked to find that the red ice at this time had turned into light purple.

Purple Ice!

This......

Running the Nine Demon Pupils, Su Jue took a closer look, and suddenly became even more shocked.

Under his ninety-fold stacked fire seal, this red ice has actually become a Grade A rare material purple ice!

Although it is slightly weaker than the real Purple Ice, as long as the refiner is experienced enough, he can directly replace the real Purple Ice.

Thinking of this, Su Jue took out another piece of black purple jade.

However, it is a pity that the ink purple jade has indeed become much purer, but it has not advanced.

"I understand, although the materials of red ice, red ice, and purple ice are of different levels, the essence is the same, but the purple ice is older and the level is higher, so the red ice has the possibility of advancement, while the ink purple jade has no ......"

Thinking about it like this, Su Jue was not only not disappointed, but even more excited.

Because most of the materials in this world are similar to Zi Bing, the older the better.

This means that most of the materials have the possibility of advancement!

"Why...... Turned into purple ice ......"

After a while, Caixiao finally reacted, looking at the purple ice in Su Jie's hand and wondering.

"It's nothing, I just wanted to tell you that the Stacked Fire Seal is more than eighty-one. Su decided.

"That'...... Can you teach me then?"

Su Jue nodded, since he showed himself in front of Caixiao, he naturally would not fail to pay, and even before long, he would be made public to the world.

"Really?" said Caixiao in surprise.

"Well, after I pass the first selection, I will hand over the back nine seals to you. ”

After speaking, Su Jue pushed the door out, and at this moment he couldn't wait to confirm his conjecture, if his conjecture was correct, then the stacked fire seal would completely change the pattern of the entire refining world.

"Purple Ice...... Could it be that the Nine Layers behind the Stacked Fire Seal can refine red ice into purple ice...... From B to A, oh my God, what do I know......"

Caixiao stood in the middle of the room with a slightly pale face, and he felt very scared at the moment.

In the refining world, materials can be said to be the hottest thing, and if there is a method that can upgrade materials, she can't imagine what kind of sensation it will cause, maybe at that time, a new era in the refining world will come.

And the flawless seal will eventually be eliminated by the stacked fire seal!

After a few days of research, Su Du confirmed his conjecture.

Ninety stacked fire seals can indeed improve the quality of the material.

Analogy with red ice, it can be refined into red ice, and red ice can be refined into purple ice.

But Purple Ice can't be improved, because Purple Ice itself is the limit of this kind of material.

And the flawless grade material Su Jue also tried it, and ninety times can only be refined, not improved.

But this is enough for Su Jue.

He believed that after this year's Burning Heaven Ceremony, his Stacked Fire Seal would once again become the only refining method in the refining world.

I couldn't help but feel a little excited.

At night, Su Jue first played in the yard with Xue'er, and only after knowing that Xue'er was asleep did he start refining the Moluo Knife.

The Moluo Knife was no longer difficult for him, and refining it was just to reduce the number of seals, so as to make his Eight Tribulations Famous Weapon Moon Star Wheel have a higher success rate.

Seven days later, Caixiao came to Su Jie's courtyard and told him the news of the first round of selection.

"You mean, you can participate tomorrow?" Su Jue was a little impatient.

"That's right, we have registered you at the registration point on the seventh, and the fee has been paid, and you can go to participate in seven days starting tomorrow. Caixiao said.

"Registration fee?" Su Jue was a little surprised.

"Of course, the materials used in the first round of selection are all provided by Burning Sky City, so we must pay a certain fee, otherwise Burning Sky City will lose money. ”

Su Jue nodded, he originally thought that the selection was made with his own materials, but now it seems that the content of the assessment should not be just refining famous weapons as he thought.

After a night of cultivation, early in the morning of the next day, Su Jue went out in good spirits.

Under the guidance of Caixiao, the two soon arrived at the No. 7 registration point.

"Su Jue, I can only go here, the examiner at the No. 7 registration point is Master Yanyun, one of the eight highly respected grandmasters in Burning Sky City, in addition to his two junior disciples, Baicang and Qihong ......"

Eight Grand Masters......

Su Jue sighed a little, the strength of this Burning Sky City was really strong, so many great grandmasters, and he didn't know how many Star Emperor-level martial artists there were behind him.

After handing over the token, Su Jue entered the gate.

Inside the gate was a huge martial arts hall, and there were already about thirty young people in the hall at this time.

Obviously, these are all here to take the test.

And in this group of people, Su Jue also found Wu Zecheng.

"Su Jue, long time no see. Wu Zecheng said coldly.

Su Jue just glanced at Wu Zecheng and stepped aside.

"Hmph, Su Jue, even if you don't pass today, I'll pull you into the water. ”

Wu Zecheng's face was gloomy, he was not an internal candidate for the Fire Sect, and like Su Jie, he had to participate in the assessment.

If he hadn't seen Su Du, he might have passed the assessment, but now that he saw Su Du, he changed his mind.

For him, if he is unknown in the canon, it is better for Lasu to go into the water together.

"Everyone!"

At this moment, two old men came out of the house and came to the front of the group.

The crowd began to fall silent.

"Today's assessment is the same as in the past, we will produce the materials from Burning Sky City, and of course you have already handed over the money for these materials. ”

As he spoke, several deacons carried a large long table and placed it on the martial arts field.

"Each of you only has one material, and the weapon you refine is, the sixth-order famous weapon Dreadnought Sword!"

In the center of the long table is a wooden plaque, and on the wooden plaque is the instrument spectrum of the sixth-order famous weapon Dreadnought Sword.

One by one, everyone stepped forward to write down the dreadnought sword's score, and then returned to its original position.

"The rules of the assessment are very simple, we will make a comprehensive evaluation according to your performance in the process after you have completed the instrument, and we will announce the candidates who have passed before this evening. ”

"Now, please take your seats, and the first stage is refining. ”

Sure enough, just like Su Jue thought, the passing criteria for the assessment were not just simple refining successes, among which refining and inscription seals were also included in the evaluation.

After a while, everyone took out the stove at the same time, and Wu Zecheng deliberately sat next to Su Jie.

"Su Jue, let's refine it together. Wu Zecheng smiled coldly.

Su Jue frowned, he had already guessed what Wu Zecheng wanted to do.

The bell rang, and everyone lit a fire at the same time, and then took the materials from the table.

Su Jue took a closer look, these materials were mainly black purple jade mixed steel, and the rest were ordinary high- and middle-grade materials.

Only when Su Du was studying the materials, someone had already begun to refine the materials, and there were many more deacons around, observing the refining of people.

Half a moment later, Su Du also began.

Refining nature starts with the simplest ordinary materials.

If it is only refined for the sake of the finished instrument, Su Jue naturally does not need to be so troublesome, but it needs to be shown to the examiner, so refining outside the furnace is the best choice.

Su Jue knew, and the others naturally knew that refining outside the furnace was not a difficult task for the people here.

On the martial arts field, the flames were shining everywhere, and the temperature also rose sharply.

"It seems that it has already begun, and we are not too late. ”

At this moment, three more people came to the martial arts hall.

Su Jue looked back and saw that one of the three was Wu Yiqing.

In addition, there is a tall woman in white with a veil and a very noble woman at first glance.

The last old man had a kind face, and his cultivation had reached the Star Emperor Realm.
