The reason why the human flying sword refining plan left by Sword is divided into three parts: "refining chapter", "refining person chapter", and "sword man chapter", is actually to make a corresponding division according to the steps of refining tools.

Refining any monk's instrument can be divided into three steps, one is the material, the second is the magic circle, and the third is to combine these two points.

The refining chapter corresponds to the magic circle, the refining chapter corresponds to the material - that is, the human body, and the sword man chapter combines these two points.

This is actually no different from the steps of refining a flying sword, except that the flying sword material is replaced with a human body.

However, the fact that the material is replaced by the human body means that the human body flying sword is decisively different from the ordinary refining flying sword.

Ordinary refining flying swords, generally speaking, before the formal refining, the design of the core circle, the selection of materials, as well as the determination of the material ratio and the degree of integration of the sword body and the circle, etc., can be tested by making various models.

Obtaining the correct values through repeated failure experiments to achieve the most perfect combination of materials and magic circles is the most important research and development process for refining flying swords.

But this obviously can't be used in the refining of the human flying sword.

Because the human body is different from ordinary materials, there is no way to use it many times, and a failed experiment may lead to the human body being scrapped directly, in other words, death.

Fang Mo had previously checked some news reports about Sword on the Pangalactic Network and the Spirit Realm Hyperspace Communication Network, as well as some rumors, and knew that this guy had killed countless lives when he first conducted the human flying sword refining experiment, and even included many monks with certain qualifications and strength.

Obviously, at the beginning, Sword used these people as ordinary human flying sword refining "materials", and the death of those people was just scrapped materials for him.

It is precisely because of this that Sword will become a galaxy A-class wanted criminal, a super criminal specially wanted by the Spiral Arm Guard General Bureau.

However, Sword is worthy of being a master of refining flying swords, and after completing countless experiments with countless human lives, he realized that the efficiency of the experiment was not high, and it was difficult to promote the overall experiment too much, so he developed a new experimental method.

That is to arrange the core circle directly inside the human body.

Different from ordinary flying sword refining, he advanced the last step of combining the core circle and the flying sword material, and directly began to conduct the core circle experiment in the human body.

In other words, let the human body, which is the experimental material, try it directly in the body without determining the core circle, and complete the design of the core circle in the human body.

This point undoubtedly has higher requirements for the experimental material, the human body, because the human body participating in the experiment must have a good cultivation strength, so that it can build and complete the magic circle in the body by itself.

So in the years that followed, there were very few ordinary people who fell into the clutches of Sword, and they were basically low-level monks.

Fang Mo didn't know what kind of god experiments Sword had done, because there was much less news about him after that, but judging from the description in the swordsman chapter that Sword Sword left by Sword, his experiments had actually been successful to a certain extent.

Because in the Sword Man chapter, he has actually left a very complete and perfect practice for the monk to complete the arrangement of the magic circle within himself.

Of course, in order to do this, you need to lay a certain foundation.

The refining chapter and the refining chapter are used to lay the foundation.

It didn't take long for Fang Mo to get these three chapters, and normally speaking, he actually couldn't meet the requirements of the Sword Man chapter.

But because of the sword qi in his body, his body has been affected by the sword qi since he was a child, and he is completely different from ordinary people and ordinary monks, he is what Sword said "perfect sword fetus".

From the very beginning, he had actually met the requirements of the Sword Man chapter for the human sword fetus.

And after Sword Ward forcibly fused that sword qi with Fang Mo's internal breath, especially after Fang Mo cultivated these days and broke through the Zhou Tian Realm, his physical body was even more in line with the requirements.

Now, he doesn't need to do much, he can easily complete the expected core circle construction in his body.

After recalling the content of the Sword Man chapter on the side of the sword in his mind, about the construction of the core magic circle in his body, Fang Mo looked left and right, made sure that no one noticed him, closed his eyes, settled his mind, and a wisp of internal breath flowed out of the sea of qi.

Different from normal cultivation, after this wisp of internal breath left the sea of qi, it did not flow through the major meridians in Fang Mo's body one by one as usual, but pulled it here and there, and slipped around.

After going around in circles like this, after countless circles in the hundreds of meridians in Fang Mo's body, a very complex and coherent pattern was gradually formed.

If you describe all the paths of this wisp of internal breath, you will find that the pattern it composes is exactly the same as the core circle in the second-generation "moth" flying sword.

Belch...... It's a bit of an exaggeration to say that it's exactly the same, but it's basically eight or nine and ten, and some of the differences are extremely small.

After confirming the integrity of the magic circle, Fang Mo drove the wisp of internal breath to circulate along the magic circle at a faster speed, and then took a light breath, and a much stronger internal breath flowed out of the sea of qi than just now.

He drove this stronger inner breath to flow quickly down the circle.

Before the week was finished, Fang Mo had already felt that something seemed to be faintly attracted around him, going deeper into his body little by little, and being incorporated into the magic circle, and began to move forward with the flow of internal breath.

Fang Mo knew that this phenomenon actually meant that the core magic circle in his body had been successfully driven, and he began to rely on the effect of the magic circle to attract the vitality energy around his body as the further driving force of the magic circle.

This is actually a sign that a well-designed flying sword should be running when it is running.

And being able to absorb the vitality energy of the whole body, incorporate it into oneself, and move with the inner breath is something that only a genuine monk can do by breaking through the subtle realm, being able to experience the vitality energy of the whole body, and being able to be urged by the inner breath exercises.

But now, with the special nature of his physical body, with the secret book of the Sword Man Chapter left by Sword, and with the core magic circle in the "Moth" flying sword that he stole to learn, he has completed this incredible move as a mere apprentice monk of the Zhou Heaven Realm.

Su Fang, who was concentrating on the design of the magic circle beside Fang Mo, suddenly turned his head and glanced at Fang Mo with a little surprise, seeing that Fang Mo closed his eyes tightly, looking attentive, but he didn't say anything, just nodded, and lowered his head and continued to concentrate on designing the magic circle.

Although Fang Mo had already experienced the special changes in his body at this time, he didn't have time to pay attention to it at all.

Now, all his thoughts are focused on the situation of the core circle in his body.

Sure enough, as he expected, although the design of the core circle of the "moth" type flying sword was not bad, there were also many problems in it.

These problems have also brought a lot of trouble to him, who is now arranging the same core magic circle in his body.

Take the 17 nodes that exceeded the standard of "Camiga parameters" as an example, and each node that exceeded the standard would make him clearly feel hindered when he passed by the operation.

In this way, not only will the internal breath not work smoothly, but the vitality energy that has been absorbed with great difficulty will also be damaged when passing through these nodes, so it will be weakened a little.

The 17 nodes that exceeded the standard were hindered one by one, and after a circle, his internal breath was damaged by more than 30%, and his vitality energy was damaged by more than 40%.

Of course, such a loss was unacceptable, and Fang Mo immediately made corresponding fine-tuning in his body, adjusting these 17 nodes to the extent that they met the standard of "Camiga parameters".

Because this magic circle is arranged in his own body, the carrier is the meridians in his body, and the fluid that makes up the magic circle is his internal breath, so it is more convenient and comfortable to change.

After several attempts, these minor problems have been completely improved, and the internal condition has been greatly improved in an instant.

However, these are all minor problems, and the main problem is the fundamental design idea of this core circle.

Fang Mo didn't know who was the person who designed this core circle, but as he had said to the two receptionist ladies before, this core circle, including the "moth" type flying sword, had a problem with the idea from the beginning.

It's obviously a civilian flying sword aimed at ordinary people, but it's so complicated, and it incorporates so many functions that require a certain amount of cultivation ability to drive and use, which is completely redundant and unnecessary.

This is not only a waste, but also makes the entire flying sword more unnecessarily bearable, resulting in the material of the flying sword must be more diverse, and it also makes the whole flying sword ridiculously heavy.

Even if there are anti-gravity measures, they are only cost-effective and meaningless.

Fang Mo must now change this circle from scratch, first, to get rid of the unnecessary things in the previous circle, and secondly, to ...... Avoid plagiarism by the defendant.

He settled down, sorted out the thoughts he had before, and combined with his thoughts when he was concentrating on studying the refining classics these days, he began to make drastic changes in his body.

"Hmm...... These two formations are completely unnecessary and cut. ”

"This piece of magic circle is too cumbersome, increasing the energy consumption of vitality, and cutting it."

"The effect of this area is bells and whistles, and it is useless to increase the power at all, so it is cut."

"Here...... Chopped. ”

"And this ......"

……

……

In response to the problem of the "moth" type flying sword that he had noticed before, Fang Mo thought about it and tried it, but he actually cut off more than two-thirds of the entire core magic array!

Before he changed the core magic circle, it was necessary to use hundreds of meridians in his body to operate at the same time to depict it, but now after he saw it, he only needed to use only 78 meridians to fully depict it.

In terms of function, although there are a lot of bells and whistles, if it is used as the core circle of a civilian flying sword, it is much stronger than before.

Whether it is the ability to absorb or mobilize the energy of the vitality, or the ability to output, it has been a whole level higher.

"Well, that's right."

Fang Mo tried it a few times in his body, making sure that there were no more minor problems in the entire magic circle, and he had no problem in urging the internal breath and absorbing the Yuan Qi energy to circulate for several weeks, and he was satisfied in his heart, and opened his eyes with a smile.

Seeing the blank paper on the table in front of him, Fang Mo smiled, thinking that although this improved core circle would not be too good, no matter what, it should be regarded as a complete circle design, and it should not be too embarrassing to hand it in.

He stretched out his hand and was about to pick up his pen and start drawing drawings, when his palm touched the table.

"Sneer, sneer—"

With a few soft sounds, several cracks suddenly appeared on the thick wooden table, which seemed to have been cut by the sword, and with a bang, they shattered into pieces and scattered.
