At this time, in addition to Zeng Xiaoyu's most eye-catching performance, there are several instrument refiners' performance is also very eye-catching.

They are skilled in techniques, refining magic tools, just like walking in idle court, just like a pair of master's demeanor.

These craftsmen were all born in the refining Hall of Lianxing sect. They had a lot of experience and had a complete inheritance of what they learned.

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

Soon, some people with skilled skills, ahead of time to complete the melting and purification of materials, into the next process.

"Not nearly!"

However, Zeng Xiaoyu is still in the process of material purification.

According to Zeng Xiaoyu's previous purification level, his purity can reach 98%.

This is much better than other senior smelters.

After all, the primary smelter is qualified if he can purify the material to 90%.

The intermediate smelter is qualified if he can purify the material to 92%.

As for senior smelters, it's good to be able to purify them to 95%.

However, the purity of 95% is too low for Zeng Xiaoyu.

The purity of 98% is not good enough for him.

Zeng Xiaoyu's goal is 99% purity.

But it's easier to purify from 97% to 98%.

But it is not easy to purify from 98% to 99%.

The difference was 0.1%, but it stopped countless smelters.

The degree of difficulty is increasing geometrically.

For every 0.1 percentage point increase in purity, the difficulty coefficient more than doubles.

"My smelting and purification techniques have been impeccable, but why can the purity of the materials inside be maintained at 98%, so it is difficult to improve it?"

Zeng Xiaoyu stood in front of the furnace, frowning.

Recently, he has been thinking about why he can't refine the best magic weapons.

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

However, the purity of materials that Zeng Xiaoyu can purify today has reached the limit of senior refiners.

Compared with other senior refiners, the purity of 98% is much higher than that of other senior refiners.

But Zeng Xiaoyu is still not satisfied, he wants to purify the material to 99%.

Only in this way can he successfully refine a magic weapon.

Zeng Xiaoyu took a deep breath and turned his mind. He thought carefully about the purification process of the whole material and tried to find out the reason.

Suddenly, Zeng Xiaoyu's look moved: is it because the temperature of the furnace is not enough, leading to the last trace of stubborn impurities not melted clean?

Zeng Xiaoyu thinks more and more reasonable.

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

Zeng Xiaoyu bit his teeth and made a big decision.

Then, he saw Zeng Xiaoyu pinch the Dharma seal, and a spirit fire emitting terrible high temperature flew out of his body.

As soon as the spirit fire flew out, it immediately raised the temperature around him.

Zeng Xiaoyu called out the spirit of fire, then immediately a finger, the spirit of fire into a light, quickly into the refining furnace inside.

Zeng Xiaoyu's practice is very risky. If the fire is not properly controlled, it is likely that his refining process will fall short.

Fortunately, Zeng Xiaoyu's affinity for fire and his ability to control the fire have reached a delicate level since he integrated the best fire spirit root into his body.

"This man has a strong fire attribute spirit root!"

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

When Zeng Xiaoyu called out the spirit fire in his body, the rostrum was concentrating on watching the audience refining utensils. Many of them showed a moving look.

In particular, Hao Yantong, the leader of huozong, became very excited when he saw Zeng Xiaoyu's fire control seal and the spirit fire.

However, this person's emotional control has reached the degree of ease.

Just now he was still in a state of extreme excitement, but the next second I saw him sitting in a serious way.

Just look at Zeng Xiaoyu's eyes, began to take a strange luster.

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

They can see that Zeng Xiaoyu is taking some risks.

At the moment, many people are concentrating on Zeng Xiaoyu's side, hoping to see if Zeng Xiaoyu will lose all his previous achievements due to his risky behavior.

When Zeng Xiaoyu was directing the spirit fire into the smelter furnace, he carefully controlled the fire power of the spirit fire, and slowly approached the smelter furnace, where the molten metal was almost melted.At this time, Zeng Xiaoyu was extremely careful and carefully controlled the fire.

At this time, the fire control is particularly important.

Once the temperature is too high, it is likely to burn out the whole beach material.

But the temperature is too low to remove impurities.

At this time, Zeng Xiaoyu's fire control is like dancing on the tip of a knife. You need to be careful.

For the control of the temperature, we also need to achieve the wonderful end of the line.

"What a thrill!"

The first time to do such a precise thing, even Zeng Xiaoyu also felt a slight sweat on his forehead, and could not help but burst a rude remark in his heart.

At this time, Zeng Xiaoyu needs a fire that is gentle and warm.

Only by combining hardness with softness can the impurities in the materials be removed without damaging them.

Therefore, Zeng Xiaoyu took a deep breath before he put the fire close to the material. Then he carefully controlled the temperature of the fire and slowly approached the material.

"How bold this little fellow is! It's clear that the smelting has been completed, but we should add a spirit fire to the furnace

"What is he trying to do? Does he think the furnace temperature is not high enough?

Don't he know that once the furnace temperature is too high, the melted materials will be vaporized, and the early efforts will be turned into water? "

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

...

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

People with a clear eye can see that with Zeng Xiaoyu's superb weapon refining techniques.

Once he followed the rules and refined them according to the process.

If there is no accident, the magic weapon he refined must be a high-quality magic weapon.

But Zeng Xiaoyu did not play according to the routine.

When people thought his material had been melted.

However, he suddenly took the material out of the furnace instead of following the routine. Instead, he put a spirit fire with terrible temperature into the furnace.

At the same time, many people began to feel some disappointment and regret for Zeng Xiaoyu.
