At this time, in the refining square, in addition to Zeng Xiaoyu's performance being the most eye-catching, there were also several refiners whose performance was also very eye-catching.

Their techniques are skilled, and refining magic weapons is like a leisurely stroll, just like a master's demeanor.

These refiners were all from the refining hall of the Star Refining Sect, and they had extremely rich experience, and the refining inheritance they had learned was relatively complete.

Therefore, these people seemed quite relaxed when refining magic weapons.

Soon, someone with skillful skills completed the smelting and purification of the material in advance, and entered the next process.

"It's not close!"

However, at this time, Zeng Xiaoyu was still purifying the materials.

According to Zeng Xiaoyu's previous purification level, his purification purity can be nine out of eight purity.

This is much better than other high-level refiners.

After all, if a junior refiner can purify the material to ninety percent, he is already qualified.

Intermediate refiners, refiners, who can purify materials to ninety or two, are already qualified.

As for the senior refiner, it is not bad to be able to purify it to ninety out of five.

It's just that the purity of ninety percent is too much for Zeng Xiaoyu.

The purity of ninety percent is still a little worse for him.

Zeng Xiaoyu's goal is to be nine out of nine pure.

However, it is relatively easy to purify from 90% to 90%.

But it is not easy to purify from 9 out of 8 to 9 out of 9.

The difference was a percentage point, but it stopped countless refiners.

The difficulty progression is increasing geometrically.

For every tenths of a percentage point of purity, the difficulty factor more than doubles.

"My smelting and purification techniques are impeccable, but why is the purity of the materials in it always maintained at 90% and 8%, and it is difficult to improve a little?"

Zeng Xiaoyu stood in front of the refining furnace, his brows furrowed.

Lately, he's been thinking about why he can't refine the ultimate magic weapon.

Zeng Xiaoyu felt that the purity of this material should be one of the reasons.

However, the purity of the materials that Zeng Xiaoyu was able to purify now had reached the limit of a senior refiner.

The purity of ninety percent is much higher than that of other senior refiners.

But Zeng Xiaoyu was still not satisfied, and he wanted to purify the material to ninety percent of the purity.

Only in this way would it be possible for him to successfully refine a supreme magic weapon.

Zeng Xiaoyu took a deep breath, his mind was racing, thinking carefully about the entire purification process of the material, and trying to find the reason.

Suddenly, Zeng Xiaoyu's expression moved: Could it be because the temperature of the furnace fire was not enough, so that the last trace of stubborn impurities was not smelted clean?

The more Zeng Xiaoyu thought about it, the more reasonable he felt.

However, at this time, the furnace temperature has been raised to the highest under his control, but it is still difficult to get rid of the impurities hidden in the material.

Zeng Xiaoyu gritted his teeth and made a major decision.

Then, I saw Zeng Xiaoyu pinch the magic seal, and a spiritual fire that exuded a terrifying high temperature flew out of his body.

As soon as the spiritual fire flew out, it immediately caused the temperature around him to rise by a bit.

After Zeng Xiaoyu summoned the spiritual fire, he immediately pointed with his hand, and the spiritual fire turned into a ray of light and quickly drilled into the refining furnace.

Zeng Xiaoyu's approach was very risky, and if he didn't grasp the heat properly, it was very likely that his refining process would fall short.

Fortunately, since Zeng Xiaoyu integrated the best fire spirit root into his body, his affinity for flames and his ability to control them have reached a meticulous level.

"This person is such a strong fire attribute spirit root!"

"And what kind of fire did he just use?"

Just when Zeng Xiaoyu summoned the spiritual fire in his body, many of the audience on the rostrum who were watching the refining instrument intently showed a moved look.

Especially Hao Yantong, the sect leader of the Fire Sect that day, suddenly became extremely excited when he saw the fire control magic seal used by Zeng Xiaoyu and the spiritual fire he summoned.

However, this person's control of emotions has reached the level of freedom.

Just now, he was still in extreme excitement, but the next second, I saw him sitting in a precarious position, looking serious.

It's just that when he looked at Zeng Xiaoyu's eyes, he began to have a strange brilliance.

Of course, many of the people present were experts in refining weapons.

They can also see that Zeng Xiaoyu's move is a bit risky.

At this moment, many people were looking at Zeng Xiaoyu's side intently, wanting to see if Zeng Xiaoyu would lose all his efforts because of this risky move.

When Zeng Xiaoyu directed the spiritual fire to enter the refining furnace, he carefully controlled the fire power of the spiritual fire, and slowly approached the refining furnace, the pool of metal liquid that had been almost smelted.

At this time, Zeng Xiaoyu was extremely cautious and controlled the fire very carefully.

At this time, heat control is particularly important.

If the temperature is too high, there is a high chance that the whole beach material will be burned out.

But if the heat is too low, it will not work, and it will not have the effect of removing impurities at all.

At this time, Zeng Xiaoyu's heat control is like dancing on the tip of a knife, and he needs to be careful and careful.

For the control of the heat, it is also necessary to achieve the best of the best.

"What a fucking thrill!"

It was the first time to do such a precise thing, even Zeng Xiaoyu felt a slight sweat on his forehead, and he couldn't help but burst into a foul mouth in his heart.

At this time, the fire that Zeng Xiaoyu needs needs needs to be gentle and warm.

The combination of rigidity and softness can remove the impurities in the material without damaging the material.

Therefore, Zeng Xiaoyu did not forget to take a deep breath before approaching the spiritual fire to the material, and then carefully controlled the temperature of the spiritual fire and slowly approached the puddle of material.

"This little guy is really bold! Obviously the smelting has been completed, but he wants to draw a snake and put a spiritual fire into the furnace!"

"What is he trying to do? Doesn't he think the furnace is not hot enough?

Doesn't he know that once the furnace temperature is too high, the smelted materials will be vaporized, making the previous efforts go down to waste?"

"I really don't understand this kid, I was very optimistic about him at first, but what he did at this time made me feel a little disappointed!"

......

In the stands, many people were shaking their heads and sighing.

Anyone with a discerning eye can see that with Zeng Xiaoyu's superb refining methods.

Once he follows the rules, refine according to the process.

If nothing else, the magic weapon he refined would definitely be a high-grade magic weapon of good quality.

But Zeng Xiaoyu didn't play cards according to the routine at all.

When everyone thought that his material had been smelted.

However, he suddenly took the materials out of the refining furnace instead of following the convention, and instead put a terrifying spiritual fire into the refining furnace.

While many people were puzzled, they also began to feel some disappointment and regret for Zeng Xiaoyu.
