Cao Hong, the head of the Cao family, was furious and agreed to Ye Fan's conditions for learning alchemy. Pen ~ fun ~ Pavilion www.biquge.info If he wins, Ye Fan apologizes in public. If he loses, let Ye Fan go to see Old Man Cao.

Yan Shien couldn't help but be ecstatic.

No matter who wins or loses, he is optimistic.

All the refiners of the Cao Mansion were all bystanders, and they couldn't help but feel sad in their hearts, the head of the Cao family was actually sowing discord by Master Yan, and was full of hostility towards Ye Fan. They couldn't help but be annoyed by the villain Master Yan, and cursed in their hearts.

But at this time, it was useless, and a battle between the head of the Cao family and Ye Fan in alchemy was inevitable.

"Senior Brother Tang, do you think Senior Brother Cao and Brother Ye, who is stronger and who is weak?"

Xing Chou was worried and was not optimistic about Ye Fan.

"Brother Ye's alchemy is very novel, and he has a broad vision in the concept of refining. But... Senior Brother Cao is the top refining king in the Imperial City, and he has a deep origin!"

Tang Dapeng sighed.

"Yes, the head of the family, the king of refining weapons in the imperial city, has been under the influence of the old man for hundreds of years, and he has already obtained the true inheritance of the old man. Although the head of the family is not visible on weekdays, he is behind him. The refining king in the imperial city who dared to compete with him would never exceed five fingers. The people who once challenged the head of the Cao family were almost all defeated, and no one could take advantage! . ”

"Brother Ye is younger after all, and his reputation is far less than that of the head of the family. He is estimated to be slightly inferior to the head of the family. ”

Everyone shook their heads and sighed.

In the hearts of everyone in the Cao Mansion, Cao Hong, the head of the Cao family, has a stronger prestige and strength in refining weapons after all. In their eyes, Ye Fan was just a cutting-edge refining king.

...

In the compound of the refining workshop, all the refiners and refining apprentices stopped what they were doing and hurriedly gathered around to watch the battle.

The battle between the Cao family master and Ye Fan's refining king was definitely a pinnacle duel between the refining kings. If you miss this pinnacle-level competition. They are afraid that they will regret it for the rest of their lives. Even if you are scolded afterwards, you will not hesitate.

The other refining kings were all engrossed, and they didn't care about the low-level refiners and apprentices, and let them watch.

This is a real alchemy competition, full of gunsmoke!

It wasn't just now that Xing Chou, Tang Dapeng, Xiang Yuanjiu and the other three refining kings asked Ye Fan about their Xuanbing. That's more about everyone asking for advice and Ye Fan's advice. There is no competition, no fireworks.

Soon, hundreds of people surrounded the Cao Mansion, all watching the battle with bated breath.

"Master Cao, I don't know how we can learn alchemy?"

Ye Fan said.

"Since it's a competition, of course it must be fair, lest others say that I am bullying the small! It is too time-consuming to directly compare refining weapons, so let's compare it to theory. You and I take turns to solve five questions each, and if the answerer successfully solves the question, he wins the game. The one who makes the question loses. If you can't answer the question, the answerer loses, and the questioner wins. Each question is limited to one stick of incense. In the end, the winner is the one who wins. ”

Cao Hong didn't plan to take advantage of Ye Fan in terms of the rules of competition.

He didn't believe at all that Ye Fan could outperform him in alchemy.

"Okay! Please ask the head of the Cao family to come up with the question first!"

Ye Fan said with a smile.

The Cao family master groaned slightly, and immediately came up with a high-level alchemy question, and said in a cold voice: "I plan to refine a fourth-order Zixia Cold Frost Sword. Some fourth-order charcoal needs to be used as fuel for cauterization. But there are hundreds of fourth-order refined charcoal, which kind of refined charcoal is asked. The most suitable for refining the Zixia Cold Frost Sword?"

When all the refiners heard this, they were all stunned.

"All the fourth-order refined charcoal can be tempered by the fourth-order Xuanjian! why do you have to deliberately choose the variety of refined charcoal?"

"Could it be that this variety of refined charcoal is also related to the ore of the refining vessel?, but there are hundreds of fourth-order refined charcoal, who knows which one is the most suitable!"

"This question. It's too out of the door~!The school is the most out of the way to refine the burning material, although it is barely a little bit related to alchemy, but the refiner will hardly pay attention to this. ”

Many refiners were very puzzled by this question, and they whispered eagerly.

When they refine their tools, they almost never deliberately choose the variety of refined charcoal.

As long as it is a grade of fine charcoal. You can use it to refine the weapon.

Even the refining kings were no exception when they were refining, so they naturally didn't pay much attention to this refined charcoal.

And the variety of refined charcoal is not what they want.

The supply of refined charcoal in the imperial city is made by fine charcoal workshops from cutting high-grade wood from the deep mountains in the distance. What kind of refined charcoal is supplied by the charcoal workshop, what kind of refined charcoal is generally used by their refiners, only in terms of price, regardless of the variety.

The head of the Cao family snorted lightly, ignored everyone with his hands, and only stared at Ye Fan coldly and arrogantly.

His exam question was not so much a test of alchemy as a test of the mastery of refining materials.

This is a refining exam question given to him by Old Man Cao in order to extinguish his arrogance after he was promoted to become the king of refining, and he was very proud to show off everywhere.

This question stunned him with a stick, and only then did he understand that the refining weapon system was as profound as the sea, and there was profound knowledge everywhere, and he didn't dare to be self-righteous anymore.

Now, he will use this stuffy stick to beat Ye Fan and let Ye Fan know how high the mountain is.

Cao Hong wanted to see how Ye Fan could solve this tricky practical problem that Old Man Cao gave him back then.

Ye Fan groaned slightly, but smiled, and said slowly: "The Zixia Cold Frost Sword uses Zixia Gold Mine and Frost Mine, which are two ore materials. This sword can also be quenched with ordinary refined charcoal, but when the refined charcoal burns violently, there will be a trace amount of dust, which will enter the Xuanjian, which will affect a little bit of the quality of the Xuanjian.

Therefore, if you want to pursue the ultimate quality, you should also consider the refined charcoal.

To refine the Zixia Cold Frost Sword, the most suitable use is the fourth-order superb Golden Light Bamboo Charcoal, or the Ice Cedar Charcoal. Because the dust after the burning of Jinguang bamboo charcoal is the same material as Zixia gold mine. The dust after the burning of fir charcoal is the same as that of cold frost ore. With these two kinds of refined charcoal, it will not affect the quality of the Zixia Cold Frost Sword.

It's just that these two kinds of refined charcoal are extremely expensive and rare, and ordinary refiners rarely deliberately look for these two kinds of refined charcoal to refine. This kind of special refined charcoal improves the quality of Xuanbing, and it is only about one or two percent of the quality. In most cases, just ordinary high-grade refined charcoal is used. ”

The more Cao Hong listened, the more shocked he became, and finally his mouth almost opened wide and fell into silence. Ye Fan actually answered the exam questions assigned to him by Old Man Cao completely back then, which was beyond his expectations. Ye Fan's skills were even deeper than he imagined.

The refiners couldn't help but be shocked and stunned.

Refined charcoal varieties and mystical varieties. You can even make a match!

It's too difficult, isn't it?

How many refiners will specialize in the similarities and differences between the dust of refined charcoal and the mystery?

You must know that there are thousands or hundreds of types of huge mineral materials and huge carbon materials, which is not something you can match one or two casually.

Ye Fan actually answered the question, which is incredible.

Ye Fan is not only proficient in alchemy. He is proficient in mineral materials and refined carbon materials.

You know, the head of the Cao family casually found a kind of Xuan Bing to torture. If Ye Fan didn't know the attributes of most of the Xuanore varieties and the attributes of the refined charcoal varieties, he would not be able to answer this question at all.

"Brother Ye actually has such a profound grasp of the varieties and effects of refined charcoal! This profound knowledge can be called difficult to match in the refining world!"

Tang Dapeng, Xing Chou, Xiang Yuanjiu and others all gasped in shock.

But soon their eyes lit up, which was a very good way to improve the quality of Xuan Bing.

Although the increase of one percent is small, for a refining king like them, whose refining level has almost stagnated, even if it can be improved a little, it is a little.

Ye Fan quickly said: "Now I'll make a question." Please answer the head of the Cao family. The same question you just asked, I plan to use the two refined charcoal materials, Jinguang bamboo charcoal and fir charcoal, to refine a mysterious artifact together. Excuse me, what is the best Xuan Bing for me to refine?"

The head of the Cao family was stunned when he heard this.

Isn't this his question the other way around!

Ye Fan's question is too simple.

"This is not simple, the golden light bamboo charcoal and fir charcoal are the most suitable for refining the Xuan soldiers, naturally it is the Zixia Cold Frost Sword!"

"That's right!"

"Isn't this equivalent to giving the head of the family a question for nothing!"

All the refiners whispered.

The head of the Cao family pondered for a moment. Just as he was about to answer, suddenly his body went cold. I almost broke out in a night sweat.

Wrong!

It's a trap!

Before, he asked, what kind of refined charcoal is best used to quench the Zixia Cold Frost Sword? Ye Fan replied that it was a fourth-order superb golden light bamboo charcoal or ice cedar charcoal, whichever one would do.

But now what Ye Fan is asking is, at the same time, use Jinguang bamboo charcoal and fir charcoal to quench the Xuan soldiers, which kind of Xuan soldiers are the best?!

These two questions seem to be opposites. But there's a huge difference.

The effect of the two varieties of high-grade refined charcoal cauterizing and quenching Xuanbing together, and the effect of burning and quenching Xuanbing with a single kind of refined charcoal is definitely different.

Ye Fan dug a trap here and waited for him to fall into it.

"Master Cao, what is your answer?"

Ye Fan looked at the head of the Cao family with a smile.

"This..."

The head of the Cao family thought for a long time. I was stunned and couldn't speak, and I was so suffocated that I couldn't get out of my heart.

He had never tried to use these two high-grade top-grade refined charcoals together to quench the Xuan Bing, what would be the effect.

It is already very difficult to grasp the effectiveness of one refined charcoal alone, who would be bored enough to burn these two varieties of charcoal together to do experiments?!

Even if it's Old Man Cao, he won't be so boring.

However, he couldn't accuse Ye Fan of being too tricky. Because this question is completely the opposite of the question he just asked.

A stick of incense time, in a flash.

The head of the Cao family still hadn't come up with an answer.

When the time comes, automatically admit defeat.

"That's too difficult, isn't it?"

"Just now I thought that the question of the head of the family was already very perverted. Now I know that the question of the Ye Refining Weapon King is a hundred times perverted. ”

"I'm afraid that even the Leaf Refining King himself doesn't know the answer!"

Tang Dapeng and several other refiners and hundreds of refiners who were watching the battle even thought about it, but they didn't come up with an answer.

Yan Shien was stunned, the confrontation between Ye Fan and the head of the Cao family, he couldn't even touch the edge of the two. The alchemy examination school of this difficulty was enough for a refining king like him to collapse after hearing it.

A wave of sorrow, a deep despair, welled up in his heart.

He can be regarded as refining weapons for hundreds of years, and even once became a senior king of refining.

However, when I saw the confrontation between the head of the Cao family and Ye Fan today, I found that he didn't even touch the edge. The problems of the two of them alone made him afraid. Not to mention, try to figure it out.

"Ye Fan, if you come up with such a refining question, you must be able to solve it yourself. Otherwise, even if you ask questions randomly, you can't count. ”

Master Yan shouted loudly.

Ye Fan glanced at him, like a fool, and ignored it.

"Brother Ye, I don't know what the mystery of Jinguang bamboo charcoal and fir charcoal quenching Xuanbing together?"

Tang Dapeng humbly sought advice.

Ye Fan said lightly: "When Jinguang bamboo charcoal and fir charcoal are quenched together, there will naturally be a special reaction, and after the fine dust produced is mixed together, it has the same effect as ice gold mine." Therefore, if the two kinds of charcoal are used together, they can be used to quench the Xuanbing, which is mainly based on ice gold ore. ”
