As the old man's voice fell, a large group of people immediately walked towards the stage, and a large area was vacated from the crowded crowd.

The test of the first level is very simple, which is to refine the refining materials.

There is a piece of iron ore the size of a human head on the small table in front of everyone. This kind of ore is very common and is usually used to forge farm tools.

If 90% of the impurities in the ore are extracted, they can be used to make weapons.

If it is refined again on this basis, it can be used as a material for top-rank ordinary soldiers.

"The first level is to extract iron ore. There is no limit to the method, and the volume of iron ore can be reduced by 50% within a stick of incense, and you can advance."

"Start now!"

After the old man finished speaking, the guard next to him took out an incense stick and lit it.

There are many ways to refine materials, such as fire refining, water refining, sand refining, etc. The development of each school leads to different refining steps.

There is no need to explain much about fire refining, which is to use flames to burn all impurities into powder. The advantage of this method is that it is simple and rough, and the speed is fast. The disadvantage is that some materials will be burned together with impurities, and the impurities that are burned into powder are difficult to discharge.

Water smelting is more complicated than fire smelting. Cleaning with water flow or other prepared liquids are generally highly corrosive substances. The advantage is that the impurities are cleaned relatively cleanly, and the disadvantage is that new impurities are easily generated.

Sand refining is actually a kind of forging method in ancient China. Carbon or other substances are added to the material for forging, and the impurities inside are replaced. With the added things, the hardness and toughness of the material are greatly improved.

These three methods are the most widely used and the most widely used.

Many refiners will learn the three methods, and change the method according to the type of material.

Lu Chuan glanced at the stage and found that the most used one was fire refining.

In fact, it is normal to say that the fire refining is too simple and rough, and the higher the flame temperature, the simpler the process.

With a powerful flame, even a person who knows nothing about refining can refine materials well.

The time for a stick of incense soon ended. Although the difficulty of the first level was not too high, more than 90% of the bastards were still screened out.

The test of smelting half of the volume of iron ore the size of a human head is actually very simple, mainly because the time is too short.

"No. 3,001 to No. 6,000, come on stage!"

The old man yelled with a loudspeaker, and Lu Chuan came on stage.

Unlike others, the refining method used by Lu Chuan is neither fire refining, nor water refining, nor sand refining, but extremely clever soul refining.

As the name suggests, it is to use soul power to refine.

Directly sink your own soul power into the material, and bring out all the impurities.

This method can be said to be the most brilliant method at present, but the requirements for the soul are too high.

The monks on the ninth floor of the Qi refining period can barely do it, but after refining the materials once, they need to rest for a long time.

Only monks who have reached the stage of transforming gods can do this relatively easily.

"It turned out to be that kid..."

Above the stands, Master Hong unexpectedly recognized Lu Chuan.

"How dare you come to participate in the Artifact Refining Conference at this level? It's embarrassing!"

Master Hong snorted coldly, his face full of disdain.

The method of soul refining is too high-end, and it is not something ordinary people can understand.

In Master Hong's eyes, Lu Chuan was holding a piece of iron ore the size of a human head in a daze at this moment, and those who didn't know thought he had resigned to his fate.

"You know him?"

The old man hosting the meeting glanced at Master Hong with a very indifferent expression.

In fact, someone like Master Hong is not qualified to talk to him, but at this moment, he is still idle, so the old man asked casually.

"Two months ago, he forced his way into the gate of the Artifact Refiner's Union, and was stopped by two guards. I scolded him. I thought he would make a move, but I didn't expect it to be a pustule, and he walked away in disgrace. Ma Master, do you know this person?"

Master Hong spoke cautiously, but his heart suddenly twitched.

Because he found that Master Ma looked at him with a hint of sarcasm, as if he was looking at a fool.

"I don't know him, but I know you're in trouble, and big trouble."

Master Ma smiled, without hiding the sarcasm on his face.

"Big trouble? Just because of him? One-third of the incense stick has been burned, and he is still holding that piece of iron ore in a daze. Just relying on such a thing, you still want to trouble me?"

Master Hong was very dissatisfied and defended in a low voice.

"In a daze? Take a closer look, isn't the size of that ore much smaller?"

Master Ma pointed in the direction of Lu Chuan and said.

Following his words, several other refiners around him also turned their heads to look.

It doesn't matter if you don't watch it, after watching it, there will be a series of gasps immediately.

I saw that the ore that was originally the size of a human head in Lu Chuan's hand turned around at some point, and half of it shrank to the size of a fist, while the other half remained the same.

"This this……"

A group of refiners were dumbfounded, seeing what happened without knowing it.

"Master Ma, what's going on here? Is it a new refining method?"

Someone couldn't bear it anymore and asked.

"This is called soul refining, not a new way of refining."

Master Ma stroked his beard and continued: "The so-called soul refinement is actually to use soul power to extract the impurities in the material. This is the most perfect refining method, and it can even remove all impurities in the material. However, soul refinement The requirements for soul power are very high, and at the worst, it can only be achieved at the ninth level of the Qi Refining Stage. This kid's cultivation is only at the third level of the Qi Refining Stage, so he should be very talented, and his soul is naturally stronger than others."

"I see! There is such a perfect method in this world!"

All the refiners took a deep breath, and all stared at Lu Chuan without blinking, trying to see some clues from it.

It's a pity that soul refining is simpler than fire refining, just like reaching into a bowl to pinch peanuts, without any technical content.

These refiners looked at it for a long time and didn't see why, but their evaluation of Lu Chuan suddenly increased a lot in their hearts.

Master Ma knew what these refiners were thinking, but he didn't explain it either.

This method of soul refining will naturally be understood when the cultivation base is reached, and it is useless even if the cultivation base is not enough.

Master Ma had a calm face, the other refiners had serious faces, and Master Hong looked like his dead father.

Regardless of the reason for what happened two months ago, it is an indisputable fact that he kicked out Lu Chuan and put him on the blacklist.

In addition, he also sneered at Lu Chuan, calling him a beast.

It would be fine if Lu Chuan was that kind of generous person, and he wouldn't care about such a small person.

But how many people are there who don't care about being called a beast?

Judge others by oneself, anyway, Master Hong can't do it.
