Hearing Ou Qianxie's words, Ye Li hurriedly straightened his mind, he chose to apprentice, naturally he didn't just pretend, he wouldn't be perfunctory about what he should learn.

"Ye Li, what's the difference between a rune flag and a foreign rune, do you know it?"

Ou Qianyi asked.

Ye Li thought for a while and said, "Master, the outer runes can only draw nine-character runes, while the rune banner can draw nine-character three-text runes. ”

Ou Qianye nodded and said, "Then do you know why the rune flag can draw the nine-character three-character rune, while the outer rune can only draw the nine-character one-text rune?"

Ye Li thought for a moment and said, "Master, I think this should be the reason for the different mediums for drawing talismans."

Although the rune paper of the outer symbol is different from ordinary paper, it is a special thing, but after all, it is only a thing similar to paper, and it is relatively fragile.

The aura accumulated when the spell is activated with more than nine characters and one penny, the outer talisman cannot bear it at all, and it will be directly destroyed by the aura. ”

Ou Qianye nodded again and said, "You're right, the situation is basically as you said, the aura condensed when the talismans above the nine-character three texts are activated, the outer talismans can't bear it at all, and they will be directly destroyed by the aura."

However, have you ever thought about the problem, a nine-character three-character rune flag needs three flags to activate, which means that a flag actually only contains one nine-character script.

So if we draw a nine-character three-text rune with three pieces of rune paper, and use three pieces of paper to carry the aura of the rune when activated, can we successfully release the charm?"

As soon as his question came out, Ye Li was asked, he had never thought about this question himself.

"Master, I don't know, I've never thought about it.

According to my own thoughts, it will definitely not work, otherwise who would make rune flags, it would be good to use rune paper.

But I don't know why, I don't know what the real difference is. ”

Hearing Ye Li's answer, a smile appeared on Ou Qianxie's face, and he said, "It's normal that you don't know, after all, you also said that you haven't been in contact with a caster, and ordinary spirit rune masters won't know this at all." ”

After a slight pause, Ou Qianye spoke: "The real reason for the difference between rune paper and rune flag is still in the material that carries the talisman, but it is not just a matter of the rune paper not being able to withstand excessive aura.

The reason why you don't use rune paper to really draw the nine-character three-character rune is because the material of the rune paper is not enough to make the three nine-character runes connect with each other and condense into a complete spell.

The structure of the rune paper is too simple to form a slightly more complex aura vein within them when it is manufactured, so they only have the effect of making the aura flow reluctantly, and cannot merge multiple rune papers together.

However, unlike the runic flag, the flagpole corresponds to the spell to be drawn on it, and uses a variety of special materials.

When these materials are burned together, the caster can use the characteristics of the materials themselves to form a simple vein within them that allows the aura to connect, so that the runes in the three runes can be condensed together to exert the effect of a complete nine-character three-text rune.

The skill of allowing the material to form the veins we need when it is burned is the most basic skill of the caster, and only by mastering this first can we have the advanced skill of guiding the veins to form rune marks in the future, and then we can successfully cast rune treasures. ”

Hearing this, Ye Li finally understood the principle of making the rune flag, and finally understood what the role of the caster was when casting various utensils.

Next, Ou Qianye took out a lot of books from his Qiankun bag and handed them to Ye Li, all of which were about the foundation of the caster.

It contains an introduction to various materials, as well as the corresponding properties of each material, and so on.

"Ye Li, you read these books in the past few days, and memorize the basic skills, and then I will teach you how to make a talisman flag.

You don't know anything about the materials now, and even if I tell you how to make a rune flag, it's hard for you to understand.

Ye Li didn't have any opinions, and after taking the book, he put it in his Qiankun bag.

In the following time, Ou Qianye took out some different metal materials, allowing Ye Li to hold them in his hand and rely on the power of his divine sense to feel them in detail.

He let Ye Li feel it over and over again, while guiding Ye Li to observe the natural lines and veins in these materials.

"Ye Li, you can see the different lines in these materials.

The core texture of each material is different, and it has its own unique rules, just like runes.

What you have to do is to identify these lines first, and pick out the core lines that are truly regular from the messy marks around you.

These lines are what you need to fuse materials and guide your veins, and they are the key to controlling the imprints of other lines. ”

With Ou Qianxie's guidance, Ye Li finally used the power of his divine sense to see countless intricate imprints in these metal materials.

Seeing these marks suddenly, Ye Li only felt that they were all chaotic lines, but after calming down and observing them carefully for a while, he finally found some patterns in them.

Following his discovery, Ye Li, as he had done in the previous competition, began to sift through these regular patterns, and soon he found a complete rune imprint.

For the next few weeks, Ye Li stayed by Ou Qianxie's side to learn the basic skills of casting.

Not only did he memorize most of the records about the properties of the material, but he also learned how to make the rune flag.

One day at the end of March, Ou Qianye took Ye Li to a cave at the back of the valley.

"Ye Li, I have already taught you the basics, today you will try to make a talisman flag.

This cave is the place I used to house the Earth Fire Refining Heavenly Furnace left by my master, and it can also be regarded as the casting room in our temporary station.

The apprentices can borrow the embers of the Heavenly Furnace to forge the talisman banner, and you can practice it today. ”

Ou Qianye said with a smile.

Hearing Ou Qianxie's words, Ye Qianzhong was also quite excited.

In the past few weeks, through the study and understanding of casters, he gradually began to become interested in casters.

Most importantly, he found that in the process of constantly looking at and exploring the core imprints inside the material, his understanding of the origin runes had become deeper.

Moreover, the power of his divine sense has gradually begun to change, and his control ability has become more and more nuanced.

It's also a lot of fun for him to be here today to practice what he's learned.
