"Miss Zhou, do you know why you can get 100 points in the first assessment, but I can only get 50 points?" Dan Xuan said indifferently with a wry smile in his eyes.

Zhou Feifei's eyes showed a trace of confusion, and she shook her head slowly, and said suspiciously: "Actually, I'm also very strange, that kind of topic seems very simple to me, but why did you only get fifty points?"

Dan Xuan shook his head with a wry smile and said, "The problem is here, it seems to you to be a very simple question, but why is it extremely difficult to come to me? Let me give you an example, you may understand! I remember that there was a question on that test paper that went like this: list a refining material that can be perfectly fused with zeolite." I wonder if you still remember this question?"

Zhou Feifei nodded slightly, indicating that she remembered, but her eyes were still full of confusion, and she said as a matter of course: "Isn't the refining material that can be perfectly fused with zeolite soft lime?"

Dan Xuan smiled bitterly and said, "Miss Zhou, you don't know, I have been delayed for a long time on this issue, not because I don't know that soft lime can be perfectly fused with zeolite, but because I know that in addition to soft lime, there are bronze, Wushui mine, sky blue jade, ......."

Dan Xuan said nearly thirty kinds of refining materials in one breath, and the names of many refining embryos, Zhou Feifei was unheard of! She just opened her mouth wide and listened to Dan Xuan say the names of refining embryos one after another, whether familiar or unfamiliar, and the shock in her eyes became stronger and stronger!

When it came to the thirty-fifth refining blank, Dan Xuan paused, let out a long breath, and continued: "Miss Zhou, you know that in my knowledge system, there are more than fifty kinds of materials that can be perfectly fused with zeolite, God knows which one this questioner wants me to fill in, so I answered this question incorrectly!"

Zhou Feifei's face was full of shock, but she was repeatedly thinking about the names of the refining blanks listed by a few Fang Cai Danxuan in her heart, and asked: "No, no, Wushui Mine is a water-biased mineral, and zeolite is a pyrogenic mineral, how can the two be perfectly integrated?"

Dan Xuan shook his head when he heard this, and said, "Miss Zhou, do you know that there is a fourth-order mysterious weapon called the 'Wuyang Sword'?"

Zhou Feifei nodded and said, "I've heard of it, but I don't know how to refine it, and in the library of our instrument clan, there is no introduction to the refining method of the Wuyang Sword!"

Dan Xuan had already guessed the answer, so he nodded and said: "Isn't this the end, in fact, the refining process of the Wuyang Sword, the most important link is to perfectly integrate the Wushui Mine and Zeolite! This is the first element of the successful refining of the Wuyang Sword, and how to perfectly integrate the fire minerals and the water minerals, this is actually a quality that the fourth-level instrument master must master, could it be that Miss Zhou, as a fourth-level instrument master, doesn't even know this?"

Zhou Feifei's eyes were full of shock, and she shook her head stupidly, she really didn't know.

Dan Xuan secretly said in his heart: No wonder, the system of the instrument clan that ranks itself is really too flawed, and he doesn't even have the basic qualities of a fourth-level instrument master, and he can even hang the badge of a fourth-level instrument master.

However, Dan Xuan only thought about it in his heart, but he didn't break it, and said, "How many fourth-order mystical weapons did the girl successfully refine that week?"

Zhou Feifei thought for a moment and said, "Since I refined the first fourth-order mystic weapon a year ago, I have successfully refined about a dozen pieces in total until now.

Dan Xuan snorted and continued: "Then, if I'm not mistaken, most of the fourth-order mystical artifacts refined by Miss Zhou should be fourth-order mystical artifacts refined by a single attribute material combination, and there shouldn't be any need to resolve attribute conflicts during the refining process, right?"

Zhou Feifei really believed it at this time, the young man in front of him was like an encyclopedia, and he knew everything.

Zhou Feifei nodded a little blankly.

Dan Xuan said secretly, and said with a smile: "So, Miss Zhou, you must know that the refining blanks of various attributes in this world are not without the possibility of fusion, the focus is on control! There is no absolute conflict, and there is no absolute fusion, the key is to look at the environment! Two blanks with different attributes may need to be fused in the refining process of a certain mysterious weapon, and in the refining of another kind of mysterious weapon, they need to resist each other to achieve balance! Everything depends on the environment!"

Zhou Feifei felt very strange when she listened to Dan Xuan's theory, and suddenly remembered that Zhou Shijie, the ninth uncle who came back from the Guyin Dynasty, seemed to have said something similar, and couldn't help but become more convinced by what Dan Xuan said.

"You, what you said is somewhat similar to what my ninth uncle said!" Zhou Feifei's words suddenly became weak, and Dan Xuan felt a little goosebumps all over his body.

"Zhou Shijie?" Dan Xuan paused, his eyes suddenly became cold, Dan Xuan still remembered that half a year ago, the so-called ninth uncle in Zhou Feifei's mouth had almost killed himself, this Qiu Danxuan would definitely revenge!

Zhou Feifei nodded.

Dan Xuan sighed and said: "Miss Zhou, although you and I are enemies, I still have to remind you, don't be restricted in your thinking, you know, for the instrument, the most important thing is not the rules, but the thinking, the ever-changing thinking!"

The confusion in Zhou Feifei's eyes seemed to be getting thicker and thicker, and her eyes were staring at Dan Xuan, as if she was waiting for Dan Xuan to continue to explain.

Dan Xuan smiled bitterly and said, "Miss Zhou, I'll give you another example, do you know how I dealt with some problems in forging jade swords today?"

Zhou Feifei looked at Dan Xuan with wide eyes, like a student listening to a class, and now, the arrogance on the face of this proud woman of the sky was almost gone!

Dan Xuan continued: "First of all, the bauxite, there are many impurities, and the amount is small, so I divided the bauxite into eight small pieces to smelt, which can reduce the waste of blanks and help alleviate the disadvantages of less supply of bauxite!

Speaking of this, Zhou Feifei had a feeling of sudden realization, and remembered the scene of Dan Xuan smashing corundum with a hammer, so many people who watched the excitement didn't understand him, but were laughing at him for whether he could refine weapons, but who would have thought that Dan Xuan did this out of such a genius idea!

Dan Xuan paused for a moment and continued: "However, there is still a shortage of bauxite ore after all, so after the fusion, in fact, there is a contradiction and conflict in the fusion embryo body, which is caused by the lack of bauxite! So, if it is Miss Zhou, you face this problem, how will you think about how to solve it?"

Zhou Feifei thought for a long time, and finally shook her head, and said calmly: "I don't know, I only know how to refine the ...... according to the requirements of the instrument."

The more Zhou Feifei spoke, the more unconfident she became, as if she couldn't be proud in the face of Dan Xuan.

Dan Xuan still shook his head with a wry smile and said, "The only way is by changing the inscription!"

"The way of inscription can also be changed?" Zhou Feifei looked surprised.

Dan Xuan still smiled bitterly, like a bitter gourd, thinking in his heart what this instrument clan had taught his children to be, the real high score and low ability!

Dan Xuan picked up a branch casually, drew it on the ground, and said as he painted: "If you can think of changing the original inscription method to this, and then like this, and then like this, and then like this......"

Dan Xuan's wrist flew and he used a branch to draw inscriptions on the ground, and then marked the relationship between the inscriptions and the energy transmission path before asking, "Miss Zhou, did you understand what I said?"

Zhou Feifei was still frowning and thinking, but she still didn't understand it and shook her head.

Dan Xuan was helpless, so he broke it down and explained it to Zhou Feifei again, this time, Zhou Feifei understood something, but she still didn't understand it halfway!

Dan Xuan explained in more detail again, and after doing so three times, Zhou Feifei finally suddenly realized, slapped his thigh, and exclaimed: "Oh my God, I see, you can even think of changing the inscription to this, just to make up for the shortcomings caused by the lack of bauxite! Such a genius thinking is really amazing!"

Seeing that this eldest lady of the Zhou family finally understood, Dan Xuan took a long breath, feeling that telling this high-scoring and incompetent Zhou Feifei was more tiring than going into battle to kill the enemy, and she didn't understand until she talked about it so many times!

Dan Xuan looked up to the sky and let out a lament, his face full of the feeling of being defeated!
