Early the next morning, Kevin went to the material store to shop, and stopped by the mercenary hall to announce Uncle Noyce's missing person notice.

Du Yuhan, who was left behind, began to learn about the extraction of magical elements under the guidance of Raphael.

He didn't know how the other modelers extracted it, but since none of them had the profession of elemental magician, and the only priest, Du Yuhan, was reluctant to let the other party work, they could only attack the big and small demon cores.

Fortunately, some low-level demon cores still have a lot of inventory, so Du Yuhan started his extravagant and wasteful journey very proudly.

In order for an enchanter to extract the elements in the magic core, the first thing to do is to stimulate the fighting spirit in the *. But Du Yuhan's situation was very special, he wasn't sure if activating the Dou Qi would work, so he opened the bracelet and placed the magic core on the small iron vault.

One second, two seconds, three seconds......

A minute passed, and the first-order earth attribute demon core did not move at all, and it was not seen that it had been absorbed by the library.

Du Yuhan was in trouble.

According to the previous operation, he only needed to put the items that needed to be extracted on the top of the warehouse, but this trick did not work for the magic element at all.

Raphael, who was sitting next to him, was silent for a moment, "The enchanter uses his own fighting spirit to absorb the magic element, and the state of the magic core after being absorbed will not become a white model." And what you're doing now is just asking the library to extract the material inside, so I think there's something wrong with your approach. ”

Du Yuhan slowly digested the other party's opinion, he looked down at the bracelet, "You mean, let me directly use the fighting qi in my body to absorb the elements, instead of directly passing the effect of the guò library?" ”

Raphael pondered for a moment and nodded uncertainly, "If it is according to the process, this is what it means." ”

Directly grasp the elements with Dou Qi, this method Du Yuhan has also tried before. It's just that the situation at that time was relatively special, the whole world had become a white mold state, although those who were grabbed by life energy did not become a white model in the end, but in the current situation of not transforming the white model, he was not sure how feasible it was.

He followed Raphael's instructions, closed his eyes and calmed down, let the fighting qi in his body run around his body with the meridians, and controlled the fighting qi to concentrate on his left wrist, and the light of the bracelet also flourished with the stirring blue light of the fighting qi.

After a long time, he suddenly opened his eyes, and his left hand clawed at the demon core on the table. Five streams of blue light started from the small screen of the bracelet, followed the broad back of the hand, and the slender fingers to the fingertips with the strongest fighting spirit, and gradually condensed into five small balls of light. At the very end, the ball of light is even compressed to a bluish-white color.

As if sensing the traction of an external force, the originally stable magic elements inside the yellow-brown magic core began to circulate uneasily, as if they were desperately trying to break free from the opponent's arrogant mercy. At first, the elements slowly flow in a fixed direction and speed, but as the acceleration increases, the speed of movement becomes faster and faster, and even the flow path begins to have some discordant intersections.

Finally, a subtle pale yellow overflowed on the smooth surface of the core. Seeing that a fraction of the element was ready to move, it was pulled back by the powerful suction of the demon core itself.

Seeing this, Du Yuhan immediately increased the operation of his fighting spirit, trying to control the element that had been shaken in his hand.

The tug-of-war situation lasted for several minutes, and the trace of magic element was finally absorbed by Du Yuhan with his fighting energy, and he lingered in his palm unwillingly. Although this little element is not much larger than the tip of a needle, it is the first time that it has been successfully absorbed.

Du Yuhan felt very excited, and hurriedly increased the operating intensity of the fighting spirit, and continued to absorb the remaining energy.

After nearly half an hour, Du Yuhan's face was flushed and his face was covered with fine sweat, and at the moment before the fighting spirit was completely exhausted, he finally absorbed all the elements in the demon core. And the magic core, which had no magical element, completely dimmed, turning into translucent black glass.

"I didn't expect it to be quite easy."

Looking at the tawny elemental ball the size of the little finger in his palm, he was very proud in his heart. I didn't expect the first attempt to extract it and it was a direct success, it seems that I am still very talented, maybe the throne of this model master is just around the corner!

"Well, you can extract an entire first-order demon core for the first time, and it's okay." Raphael nodded in agreement, but there was still no expression on his face.

Hearing this, Du Yuhan was even more proud, and he couldn't wait to show Kevin the results of this time and share his joy with the other party. One didn't pay attention, and the fighting spirit was not able to control it skillfully, and the elemental ball seemed to be squeezed by an external force, and a circle of ripples rippled on the surface, and the ball twisted a little, and then dissipated silently in the palm of the hand.

"Ahh My balls! Du Yuhan wailed, but unfortunately he was weak. He looked at Raphael with a calm face depressedly, "Why does this element still collapse?" The materials I extracted in the past will not have any problems no matter how you rub and press them. ”

Raphael raised half of his eyebrows, "You also said that it was a material, but now it is not a material at all, but a magic element, and if you don't control it properly, it will definitely collapse." Don't you even know this common sense? ”

Du Yuhan: ......

Then, the illiterate Du Yuhan popularized the basic knowledge of magic under Raphael's disdain.

This world is surrounded by all kinds of magical elements. But these elements are in a disorderly state of dissociation, and they do not cause any power at all. The reason why the mage can cast spells is also to use the energy in the body to mobilize the elements outside the body, so that they are sorted according to a certain sequence, so as to combine various powerful spells.

If you take a magic spell that has already been sequenced, and give up the sorting control, those elements will immediately fall apart.

However, if the elemental ordering is forcibly dissolved, this will also bring a certain danger of backlash. The more advanced the spell, the more dangerous it will be. If certain aggressive elements, such as Shadow Elementals and Fire Elementals, are forcibly disbanded and sorted, they will even actively attack the caster.

"Then why didn't I get backlashed just now?"

At that time, he only felt a breeze blowing in his palm, and the elements dissipated, and he did not experience the so-called backlash at all.

As a result, the illiterate Du Yuhan was despised again.

"You just absorbed the weakest earth attribute element, and it's only at the first level, so you can be counterattacked, how amazing must that be?"

Du Yuhan squatted depressedly in the corner of the wall and drew circles.

Well, now everyone knows that he is illiterate.

In this way, it is no wonder that the elements cannot be loaded in glass bottles, like other materials, but need to be stored in containers specially made by the zài inscriptionists.

After silently sorting out the process of absorption, Du Yuhan picked up another magic core and continued to practice.

After absorbing three or four cores, he discovered a blind spot.

This extraction method is time-consuming and labor-intensive, and the production capacity is extremely low. He probably estimated the amount of elements he had just extracted, which was not enough to condense into a first-order spell. Although the higher the level of the magic core, the more magical elements it contains, even if it is a holy level magic core, the elements inside it are estimated that it is not enough to form a seventh-order spell.

At that time, Kareid would easily make a fifth-order spell, if he followed this process, how many high-level magic cores would be needed? He didn't know how strong the attack power of the Holy Rank Demonic Beast would be, but he shouldn't say that the Holy Rank was running all over the street, right?

Raphael could not answer this question either. After all, the enchanter mainly relies on the elements of the magic core to reorganize the enchantment effect, and he does not know if there is a better way for the modeler.

Du Yuhan frowned slightly, his eyes stared at the small brass-colored iron vault on the table, holding his chin and meditating, repeatedly pondering Kared's answer at that time.

Usually modelers rely on iron libraries to extract materials, and Khared also mentioned at the time that elements are extracted from libraries. Even if other modelers extract the magic elements from spells, it stands to reason that they are also magic elements, and they can't extract the magic core, right?

Could it be that the elements are separated by a shell on the outer layer of the core?

But what about those circles that rely on the energy of the demon core?

Fighting energy activates the bracelet and uses the library ......

Suddenly, Du Yuhan had a flash of inspiration.

"Could it be that you use your fighting spirit to directly activate the iron storehouse, and no longer use the guò bracelet?"

Hearing this, Raphael was a little puzzled, "Aren't you modelers all using the role of guò bracelets?" ”

Du Yuhan shrugged.

According to past experience, modeling only needs to activate the bracelet to basically complete most of the processes, as for whether the iron library can be activated with fighting energy, Du Yuhan is not sure. But now there was no one to give professional advice, so he had to try everything.

Grabbing the small iron vault, Du Yuhan once again stirred up the fighting spirit in his body, and consciously passed it to the left hand of the supporting vault.

A magical scene happened.

Under the activation of the Dou Qi, I saw that the dark yellow iron depot started from the base, surrounding a circle of pure white Dou Qi. The iron vault seemed to be conscious, desperately absorbing pure white energy. With the penetration of the fighting qi, the energy spread rapidly upwards along the surface of the iron warehouse, and the originally smooth and textureless brass-colored surface actually showed a layer of golden yellow magic patterns.

The magic pattern had a strange shape, and it looked a bit like a twisted cluster of fiery silkworm flowers. The golden energy flows slowly within the engraving, appearing brilliant.

Seeing this, the two were stunned.

I didn't expect that the original inconspicuous iron depot would have such a cool effect under the effect of vindictiveness, and it seemed that its function had become more powerful. Tsk, why didn't he find out before?

Du Yuhan was surprised and excited, and he couldn't wait to pick up a magic core and throw it into the warehouse. The iron vault seemed to feel the surging of magical elements, and the magic patterns on the outer surface immediately shone brightly, and the energy flow speed inside became faster and faster, and there was even a small pale yellow elemental storm on the outer layer of the iron vault. The light on the engraved lines gradually brightened and dimmed, like the rate of biological respiration, trembling regularly.

After a while, the light on the outer perimeter of the iron depot slowly dimmed until it finally subsided.

Du Yuhan gently lifted the iron box and looked inside, only to see a thumb-sized ball suspended in the center of the iron warehouse, and the outer elemental particles slowly rotated along the center of the ball as if they were attracted and bound. And the magic core, which had long been devoid of magical elements, was lying quietly at the bottom of the iron vault.

It was exactly as he had guessed.

Under the same first-order magic core, the number of elements extracted from the library is obviously more than that extracted manually, and it is also more time-saving and labor-saving. Although the object of extraction is only the magic core, according to this setting, it is estimated that the elements of high-level spells are also extracted in this way. The first is to activate the iron vault with Dou Qi, and then use the energy of the vault to extract the magic elements in the spell.

After activation, the power of the iron vault is greatly increased, so you don't have to worry about spells smashing the iron vault. However, the limit of the spell impact that the library can withstand will need to be tested later.

Looking at this elemental ball, which was a little larger than the previous few times, Raphael's eyes flashed with a hint of appreciation, "It's not bad." ”

Du Yuhan's heart blossomed, but he didn't expect it to really make him right.

If this magic element can form a low-level spell, then to form a high-level spell, is it only necessary to increase the amount of elements per unit volume?

Thinking of this, he began to try to throw two magic cores into it again, and after a burst of bright light, except for the size of the ball of the magic element, the color was not any different, and it seemed that the density of the element had not changed in any way.

Du Yuhan was puzzled, and he tried to consult Raphael.

Are you an idiot? Out of upbringing, Raphael didn't say this sentence, but Du Yuhan could already fully feel the other party's contempt and helplessness.

"As I said earlier, the level of a spell is not simply determined by the density of the elements, but by the combination of the magical elements." Raphael lifted his forehead weakly, "What you are extracting now is only the magic element of the spell, and there is no order at all." Just like if you are extracting a first-order earth bullet spell now, even if you extract it ten more times, it will only be ten first-order earth bullets, not a tenth-order earth tornado spell. ”

Du Yuhan was a little embarrassed, as if this was indeed the case.

The same carbon element, no matter how many pencil leads you collect, you can't make a diamond......
