In a rage, Cao Hong, the head of the Cao family, agreed to Ye Fan's conditions for practicing artifacts. Yishu·1·?? If he wins, Ye Fan apologizes in public. If he loses, he will ask Ye Fan to see Mr. Cao.

Yan Shien couldn't help but feel ecstatic.

No matter who loses and who wins, he is optimistic.

The weapon refiners in the Cao Mansion were all watching and couldn't help but feel sad. The head of the Cao family was sowed by Master Yan and was full of hostility towards Ye Fan. They couldn't help but be angry at Master Yan, the villain, and cursed in their hearts.

But it was useless at this time. A competition between the head of the Cao family and Ye Fan in weapon refining was inevitable.

"Senior Brother Tang, do you think that Senior Brother Cao and Brother Ye are stronger and weaker?"

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

"Brother Ye's weapon refining technique is very novel, and he has a broad vision in terms of weapon refining concepts. But Brother Cao is the top weapon refining king in the imperial city, with a deep connection!"

Tang Dapeng sighed.

"Yes, the weapon refining king of the head of the family, who was the most powerful weapon refining king in the imperial city, has been under the influence of the old man for hundreds of years. Although the head of the family is not visible or exposed on weekdays, his foundation is behind him. The weapon refining king who dares to compete with him in the imperial city will never pass by five fingers. Almost all those who challenged the head of the Cao family were defeated, and no one can take advantage of it!"

"Brother Ye is younger after all, and his fame is far less than that of the head of the family. He is probably slightly inferior to the head of the family."

Everyone shook their heads and sighed.

In the hearts of the people in the Cao family, Cao Hong, the head of the Cao family, was stronger after all. In their eyes, Ye Fan was just a new weapon refining king.

In the courtyard of the weapon refining workshop, the weapon refining apprentices stopped their work and hurriedly surrounded and watched the battle.

The battle between the head of the Cao family and Ye Fan's weapon refining king is definitely a peak duel between the weapon refining king. If you miss this kind of peak-level competition, they will only regret it for life. Even if they are scolded afterwards, they will do whatever they want.

The other weapon refining kings were all focused, regardless of the low-level weapon refiners and apprentices, and allowed them to watch.

This is a real competition for weapon refining techniques, full of smoke!

It wasn't just that Xing Chou, Tang Dapeng, Xiang Yuanjiu and other three weapon refining kings asked Ye Fan about their Xuan soldiers. It was more about asking everyone for advice and advice from Ye Fan. There was no question of competition, and there was no fireworks. One? Reading a book? · 1? ·

Soon hundreds of people from Cao's mansion surrounded him and were watching the battle with their breath holding their minds.

"Master Cao, I wonder how we can practice artifacts?"

Ye Fandao.

"Since it's a competition, of course it's fair, so as not to say that I'm bullying the small ones by the big ones! It's too time-consuming to compare the refining of weapons, so compare the theory. You and I take turns to give five questions each. If the answerer successfully answers, the winner will win one game, and the answerer will lose. If the answerer cannot answer, the answerer will lose, and the answerer will win. Each question is limited to one stick of incense. In the end, the winner will be the winner."

Cao Hong did not intend to take advantage of Ye Fan in terms of the rules of the exchange.

He didn't believe it at all. Ye Fan could beat him in weapon refining.

"Okay! Please give the question to the head of the Cao family first!"

Ye Fan smiled.

The head of the Cao family pondered for a moment and immediately came up with a high-level artifact refining technique and said coldly: "I plan to temper a fourth-level Zixia Cold Frost Sword, and I need to use some fourth-level refined charcoal as burning fuel. But there are as many as hundreds of fourth-level refined charcoals. Which kind of refined charcoal is the most suitable for tempering the Zixia Cold Frost Sword?"

When the weapon refiners heard this, they were shocked.

"All fourth-level fine charcoals can temper the fourth-level mysterious sword! Why do you still have to deliberately select the varieties of fine charcoal?"

"Could it be that the variety of refined charcoal is also related to the ore of the refining tool? But there are hundreds of fourth-level refined charcoals, who knows which one is the most suitable!"

"This question is too off-the-spot~! The one who took the exam was the most off-the-spot refining combustion material. Although it was barely related to the refining technique, the refiners would hardly pay attention to this."

Many weapon refiners were very puzzled by this question and whispered.

When they refining weapons, they almost never deliberately select varieties of refined charcoal.

As long as it has sufficient grade, it can be used to refine weapons.

Even if the weapon refining kings are no exception when they are tempered, they naturally don’t pay much attention to this refined charcoal.

Moreover, the variety of refined charcoal cannot be found just by whatever they want.

The fine charcoal supply in the imperial city is made by fine charcoal workshops cut high-level wood from the mountains far away. What fine charcoal is supplied by fine charcoal workshops, their weapon refiners usually use fine charcoal, only about the price, regardless of the variety.

The head of the Cao family hummed softly, ignored everyone with his hands, and stared at Ye Fan coldly and arrogantly. When he read the book??·1·

His test question is more about proofreading the mastery of refining materials than about weapon refining techniques.

This was a weapon refining test question that Mr. Cao gave him to destroy his arrogance after he was promoted to the king of weapon refining.

This question shocked him with a blow, and then he realized that refining weapons was as profound as the sea, and there were profound knowledge everywhere, so he didn't dare to be self-righteous anymore.

Now, he will use this scoundrel to hit Ye Fan and let Ye Fan know how high the mountain is.

Cao Hong wanted to see how Ye Fan could solve the tricky practical problem that Mr. Cao gave him back then.

Ye Fan pondered for a moment, but smiled, and said slowly: "The Zixia Cold Frost Sword uses Zixia Gold Mine and Frost Mine as ore materials. You can also temper this sword by using ordinary fine charcoal, but when the fine charcoal burns violently, there will be traces of dust that will enter the Xuan Sword, which will affect a little quality of the Xuan Sword.

Therefore, if you want to pursue the ultimate quality, you must also consider the fine charcoal.

The most suitable for tempering the Zixia Cold Frost Sword is the fourth-level top-grade Golden Light Bamboo Charcoal or ice fir charcoal. Because the dust burned by the Golden Light Bamboo Charcoal is the same as the Zixia Gold Mine. The dust burned by the Ice Fir charcoal is the same as the Cold Frost Sword. Using these two kinds of refined charcoal will not affect the quality of the Zixia Cold Frost Sword.

However, these two kinds of fine charcoals are extremely expensive and rare. Ordinary refining shops rarely deliberately search for these two fine charcoals to refine weapons. This special fine charcoal improves the quality of Xuanbing, which is about one percent or two. In most cases, only ordinary high-level fine charcoals are used.”

Cao Hong became more and more shocked as he heard it. Finally, he opened his mouth wide and fell into silence. Ye Fan actually answered the test questions assigned to him by Mr. Cao back then, which was beyond his expectations. Ye Fan's skills were deeper than he imagined.

The weapon refiners were shocked.

The refined charcoal varieties can actually match the mysterious ore varieties!

This is too difficult.

How many weapon refiners will specialize in studying the approximation and difference between fine charcoal dust and black ore?

You should know that there are thousands or hundreds of types of mineral materials and huge charcoal materials. This is not something you can match just by just saying one or two.

Ye Fan actually answered the question, which was incredible.

Ye Fan is not only proficient in refining weapons, but also proficient in mineral materials and refined carbon materials.

You know, the head of the Cao family casually found a kind of mysterious soldier to question it. If Ye Fan did not know the attributes of most of the mysterious ore varieties and the attributes of refined charcoal varieties, there would be no answer to this question.

"Brother Ye actually has such a profound understanding of the varieties and effects of refined charcoal! This profound knowledge is hard to be seen in the artifact refining world!"

Tang Dapeng, Xing Chou, Xiang Yuanjiu and others were all in shock and took a breath of air conditioning.

But soon their eyes shone, which was a very good way to improve the quality of Xuanbing.

Although one percent improvement is small, for a weapon refining king like them, even if it can be improved a little.

Ye Fan quickly said: "Now I'm going to ask the head of the Cao family to answer it. It's the same question you just asked. I plan to use the two fine charcoal materials, Golden Bamboo Charcoal and Fir Charcoal, to refine a mysterious weapon. May I ask, what mysterious weapon is best for me to refine?"

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

Isn't this his question asking in the opposite way?

Ye Fan’s question is too simple.

"This is not simple. The most suitable Xuan soldiers for tempering of golden bamboo charcoal and fir charcoal is naturally the Zixia Cold Frost Sword!"

"yes!"

"Isn't this the question to give the head of the family for free?"

The weapon refiners whispered in silence.

The head of the Cao family thought for a while and was about to answer the problem, suddenly his body became cold and he almost burst into night sweats.

wrong!

This is a trap!

He asked before, what kind of refined charcoal is best for Zixia Lengfrost Sword? Ye Fan answered that any of the fourth-level top-grade golden light bamboo charcoal or ice fir charcoal can be used.

But what Ye Fan asked now is, at the same time, using golden bamboo charcoal and fir charcoal to temper the mysterious soldiers, which type of mysterious soldiers is best to temper?!

These two questions seem opposite, but there are huge differences.

The effect of two varieties of high-level fine charcoal burning and tempering the Xuan Soldiers together, and the effect of burning and tempering the Xuan Soldiers alone 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, but couldn't say it. He was so stuffy that he couldn't breathe.

He has never tried to use these two high-level and top-quality charcoals to temper the Xuan Soldiers together. What would be the effect?

It is already very difficult to master the effectiveness of a refined charcoal alone. Who would be so bored that they used these two varieties of charcoal to burn together to do the experiment?!

Even Mr. Cao wouldn't be so boring.

But he couldn't accuse Ye Fan of being too tricky in setting the questions. Because this question was completely a question that he just asked the question.

A stick of incense passed in a flash.

The head of the Cao family still did not come up with the answer.

When the time comes, you will automatically admit defeat.

"This question is too difficult!"
