Take refining flying swords as an example.

If you want to successfully refine a flying sword, you must first have requirements for materials.

Different flying swords have different requirements.

The materials used in the third-generation "Flying Galaxy"-03 type civilian basic flying sword and the "Shalan" flying sword used by Lingyun Fairy are absolutely different.

The most basic requirement for the materials required for the Sha Lan Flying Sword is that it must be enough to withstand the internal pressure of a great master of the Divine Realm like Ling Yun Fairy, otherwise the flying sword will break as soon as it is used, which is naturally meaningless.

Therefore, the cost of the materials required to refine the Shalan Flying Sword is probably tens of thousands or even hundreds of thousands of times that of the Flying Galaxy-03 Flying Sword.

But this doesn't mean that refining the Flying Galaxy-03 Flying Sword is much easier than refining the Shalan Flying Sword.

The requirements for refining a flying sword that can be used by ordinary people are completely different.

It requires materials that are universal, versatile, and inexpensive.

And to make these low-level materials combine and achieve the goal of being able to carry people flying, the difficulty is no less than designing the Shalan Flying Sword.

The second is material matching.

No matter how well the materials are prepared, if you can't find a perfect matching scheme, you won't be able to achieve the desired result, or even be able to refine it successfully.

Then there's the core, the most important core circle design.

Different core circles bring completely different effects.

The flying sword that the high-level monks need is to be able to exert powerful lethality better, faster, and more conveniently, so the core magic circle requirements are also biased towards high lethality.

The ordinary civilian version of the flying sword is different.

The civilian version of the flying sword cannot be powered by the civilians who control them through internal breath condensation, and the reason why the flying sword suitable for them can fly is that the flying sword is different from ordinary flying machines, it is powered by the magic circle inside the flying sword to absorb energy.

At the same time, in order to protect the safety of the passengers, ordinary civilians, the core circle of the civilian version of the flying sword also has a series of functions such as shielding, protection, buffering, and control, and the design complexity is higher than that of the flying sword used by high-level monks.

In addition, the design of the flying sword also needs to take into account the aerodynamics and cosmic space energy fluidics, the compatibility of space energy with different materials, and the aesthetics of the appearance......

There are even private customized flying swords, and the design requirements that need to be completed according to private requirements are even more varied and difficult to list one by one.

Fang Mo was still full of confidence when he first looked at it, feeling that he was carrying the refining secret given by Sword, a famous refining master in the galaxy, and as long as he had a little foundation, he could easily become a powerful refining master.

However, after reading a few basic classics of refining, the more he looked at them, the more cold he felt in his heart.

Alchemy is an incomparably complex system of knowledge, and it is a fool's dream for him to want to become a refiner just based on the refining chapter left by Sword.

"Ma Dan, if you want to make money with this thing, at least don't even think about it for a short time."

Fang Mo was helpless in his heart, knowing that he was too naïve before, and he thought about refining the weapon too simply.

But he is not discouraged, after all, the more complicated this thing seems, the more it proves that it is very rich, and the only problem is that it is difficult to convert into money in a short period of time.

And now after learning some basic theoretical knowledge related to refining, he found that he also understood the refining chapter left by Sword more thoroughly and easily.

Obviously, all of Sword's theories are based on refining weapons, and learning more about refining weapons will also be of great help to understand the refining chapter and the final sword man chapter.

Knowing this, Fang Mo cheered up and focused on absorbing new knowledge.

In the next few days, in addition to attending classes every day, Fang Mo spent all his free time in the school library, going straight to the elite library, seizing every bit of time to tirelessly study the basic knowledge and theory of refining.

Whenever this happens, he can't help but complain in his heart about the stinginess of the Heavenly Sword Gate.

Although he obtained the permission to enter the elite library through the level, the Open Heaven Sword Gate has special confidentiality regulations for the materials and classics in the Scripture Pavilion, and it is not allowed to take them out or copy the data.

In addition, if he wants to enter the elite library, he can only connect successfully within the library, so Fang Mo can only go to the library every day to study, and there is no way to take the materials and classics home to study slowly.

If he could take it out casually, Fang Mo could guarantee that his learning progress would be much faster than before.

Of course, Fang Mo was not idle after returning home.

In addition to learning some refining knowledge and filling himself with theories in this area, for Fang Mo, the most important thing was cultivation.

Although it had only been a few days since he cultivated and refining people, Fang Mo had already clearly sensed the changes in his body.

His physical body was obviously stronger than before, but his internal breath was also becoming more and more affected, becoming more and more like that sword qi.

However, in general, it is still different, compared to the sword qi that has plagued him since his mother's womb before, although his internal breath characteristics have changed, and his sharp qi is becoming more and more sharp, extremely powerful, but it will not cause obvious damage to his body like that sword qi.

Of course, there is still damage, but it is much better than before.

After a few days of such a busy and tense day, Fang Mo once again received a communication from Zheng Xuan.

"Hey, Fang Mo, are you free at night?"

"What? Sparring is alive again? ”

After receiving Zheng Xuan's communication, Fang Mo was very happy, because Zheng Xuan came to him, usually to find him to spar.

This is a job that has money to be made, and now if Fang Mo wants to better cultivate the refining chapter and improve the strength of his physical body, he must have more body fluid support, then he needs more money, of course, he hopes to have more opportunities to make money.

"Well, I'll look for you by name." Zheng Xuan's tone was a little strange.

"Call me by name?" Fang Mo also had a surprised expression. "Could it be that Ouyang De introduced it again?"

"Then I don't know." Zheng Xuan did not give an answer. "Anyway, the other party said that if she can be satisfied, he will give you additional money. What do you think? Interested in coming? ”

"Nonsense, of course I'm interested."

Fang Mocai didn't care who introduced him to him, as long as he had money to make, he agreed in one bite.

After discussing the details of the evening meeting with Zheng Xuan, Fang Mo thought about it and felt a little pity.

If you want to be a sparring partner at night, you won't have time to go to the elite library anymore, and you have to waste a day of time to improve the knowledge and theory of sword refining.

But there is no way, whether it is to improve his own strength, or to consider the needs of life, and more importantly, to pay off debts, making money is his top priority.

Even if it's just to improve refining tools, you'll have to spend money on materials in the future.

"That's it, let's take a day off today."

Fang Mo shook his head, turned off his personal terminal, and was about to go back to class again, when the head teacher suddenly came over.

"Fang Mo, I heard that you have been borrowing classics on refining weapons in the past few days?"

Fang Mo nodded, not surprised that he knew what kind of books he was borrowing.

He was using the permission given by the degree, and it was not surprising that the degree knew what he was borrowing, it only showed that he was still paying extra attention to Fang Mo.

"Yes, Mr. Cheng. Didn't I say it before, I'm a little interested in refining weapons. However, it is more difficult to get hold of this kind of classics outside, so I would like to ask you to go to the elite library to consult them. ”

"Well, I get it." Du looked at Fang Mo carefully, groaned slightly, and asked, "So...... Are you really interested in refiners? ”

"Yes."

"That's it......" Du touched his chin, as if thinking about something, and after a while, continued: "Your progress in cultivation is not particularly good, and it is not bad to think about refining weapons instead. If you are willing to work hard, you may be able to find a new direction for yourself, which will also help you in the future. ”

"Yes, Mr. Cheng, that's what I thought."

No matter what the degree is, Fang Mo just needs to smile and nod yes anyway.

He knew that the degree actually cared about himself, but he couldn't tell the truth to the degree, just like he couldn't tell himself as a sparring partner outside.

"Since you're really interested in refining weapons, well, I happen to have a ticket here, maybe it will be useful for you." The degree suddenly said.

"Tickets?" Fang Mo was stunned. "What tickets?"

"The day after tomorrow is a weekend, and the city will hold an exhibition related to refining weapons organized by the Jingnan City Government, which will include many representatives from the refining department of the Xiuzhen Academy, as well as some Xiuzhen sects and some companies that make cultivation props. Since you are interested in refining weapons, you can go to this exhibition. Even if you can't understand a lot of things for the time being, it's good to open your eyes. ”

After that, he turned on the personal terminal on his wrist and motioned for Fang Mo to open the personal terminal as well.

"Come on, I'll authenticate the e-ticket to you, and you can just go directly when the time comes."

Fang Mo was a little stunned, and did not stretch out his hand, but looked at the degree blankly, scratched his head and asked, "That...... Mr. Cheng, you are too good to me, right? Aren't you afraid that other classmates will be jealous if they find out? ”

"They're a ghost vinegar!" Degree glared at Fang Mo. "You're thinking too carefully about your classmates, aren't you? Everyone knows the situation in your family, and it is only natural that I take special care of you, what can they say. Okay, less nonsense, come and get the tickets, remember to see and listen more at the exhibition, and if you can, it's best to ask more, so that you can gain knowledge. Got it? ”

Fang Mo was no longer polite, smiled, opened his personal terminal, and let the degree transmit the electronic ticket.

"Alright, go ahead, keep up the good work. In case you can become a generation of refining masters in the future, the teacher will be able to follow you. ”

He patted Fang Mo on the shoulder and turned to leave.

Fang Mo looked at the degree in the distance, and his face couldn't help but show a hint of emotion.

He has been living a difficult life alone since he was a child, and the reason why he can still maintain his current healthy, optimistic and upward attitude is that he has met many good people like Mr. Cheng.

"But if Teacher Cheng knew that the purpose of my actual learning to refine weapons was to refine myself into a flying sword, what would I think?"

Fang Mo touched his chin, pondered for a moment, shook his head, and decided not to say anything about this matter in the future.
