Chapter 389 (1/2)

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.
