Lu Ling opened the scroll in his hand, and the cultivation method of the "Fire Accumulation Technique" immediately came into view. The cultivation method of the three-star spell was generally not complicated, so Lu Ling quickly understood the steps and memorized them in his mind.

As a special auxiliary spell for the fire element, the fire storage technique is nothing more than to form a vortex through the release of its own fire element, so as to gather the fire element scattered between heaven and earth, and the use of this method can avoid ingesting the other nine elements while absorbing, which will not lead to the dilution and offset of the required fire element, and can also save the step of refining and removing impurities, saving a lot of time.

Lu Ling followed the method taught in the scroll, extracted a part of the remaining fire element in the Elemental Pill in the Qi Palace and placed it in the palm of his hand, the fiery red hot air flow churned in the palm of his hand, and then Lu Ling sealed his hands, holding the flame air flow between his hands, and under the urging of the seal, the flame air flow began to rotate rapidly, forming a palm-sized flame vortex.

When the flame vortex was circling, a suction force began to come out from the center, and in the space around Lu Ling, a trace of pale red air began to converge from all directions, like a tributary that flowed into the sea, pouring into the flame vortex one after another.

More and more fire elements merged into the vortex, causing the suction force that erupted to become more and more intense, and soon after absorbing a large amount of fire elements, the flame vortex that was originally as big as a palm had now become the size of a human head, and this absorption speed surprised Lu Ling.

In these short ten minutes, the amount of fire elements absorbed by the flame vortex was already comparable to the amount of fire elements that Lu Ling had absorbed for nearly an hour before.

It's just that Lu Ling quickly sensed that something was wrong.

The flame vortex stopped running after reaching the limit of the fire element that could be accommodated, it was quietly suspended in the air, and after Lu Ling dispersed the seal in his hand, the flame airflow quickly began to contract, and finally condensed into a thumb-sized fiery red pill, the small pill contained an extremely large power of the fire element, and even the space was scorched and distorted by the high temperature heat emitted from it.

However, the question now is, how do we inhale these highly concentrated fire elements that have gathered together into our bodies?

Lu Ling carefully flipped through the scroll, but he didn't get any hints, he could only stare at the Flame Pill dryly.

"Dan Pill, do you want me to swallow it?" Lu Ling's mind suddenly had such an idea, but this thought made his eyelids jump.

After all, the behavior of "swallowing fire" that is beyond common sense is too unbelievable, and most of the fire elements in the pill have not been refined by him, that is, they will also cause harm to themselves.

If he swallowed it like this, Lu Ling's throat and esophagus would probably be burned black in an instant, and he couldn't do this kind of stupid thing.

Lu Ling looked at the pill helplessly, and just when he was in a hurry, he suddenly had a flash of inspiration, and with a finger pick, several fire element airflows out of the pill and hovered around it. These were the fire elements that Lu Ling had used to condense into a vortex before, they came from the elemental pill in his own body, and they had already been refined by him, if he wrapped the pill with these harmless fire elements and swallowed it, it might not cause damage.

So Lu Ling used those fire elements to wrap the pill firmly, and then took the pill in his hand, and the flame pill that was originally extremely hot was wrapped in the fire element he refined, and it became incredibly like room temperature.

After taking a deep breath with apprehension, Lu Ling no longer hesitated, threw the flame pill into his mouth and swallowed it, the pill immediately flowed down his throat quickly, and sure enough, it was not to Lu Ling's surprise, these outside furious fire elements did not cause any harm to Lu Ling's body under the encirclement of their own gentle fire elements, and finally entered Lu Ling's qi palace safely, and soon they were easily refined by Lu Ling and became a part of the elemental pill.

This Fire Pill alone had almost replenished most of the fire element he had consumed yesterday, and the time it was used was even less than half of what he usually needed.

The buff brought by this "fire storage technique" can be seen.

"The auxiliary spell is really not ordinary!" Lu Ling sighed sincerely, spells like the "Fire Accumulation Technique" that can speed up cultivation are very scarce, if they are placed in the Demon Spirit Academy, I don't know how many people will compete frantically. And in this huge fairy palace, this "fire storage technique" is only the lowest level of auxiliary spells.

After eating one Fire Pill, Lu Ling was still unsatisfied, and he immediately set out to condense the second Fire Pill. However, when the fire element in his body was completely replenished, he found that refining the fire element would become extremely difficult.

But it's understandable when you think about it, after all, it's obviously far easier to increase the water in a barrel than to increase the capacity of the barrel itself.

And if the capacity of the Elemental Pill in Lu Ling's body could be further increased, it would mean that he would soon advance to the middle stage of the Yun Qi Realm.

Therefore, he did not blindly use the fire storage technique to gather a large number of fire elements between heaven and earth, but condensed them into small pills and refined them one by one. Although the speed is relatively slow, the amount of fire elementals that the Elemental Pill can hold is steadily increasing at a rate that is visible to the naked eye.

At this rate, it may soon be able to reach the level of the middle stage of the Qi Accumulation Realm.

And so it went on for three days.

Lu Ling, who was sitting on the boulder, exhaled a scorching breath from his mouth, and his eyes showed a satisfied look as he looked at the scene below the mountain.

In these three days, he finally used his demonic qi to eliminate the last trace of thunder power left in his body, and the injuries in his body were completely healed.

And the amount of demonic qi hovering around the Source Demon Array had also increased a lot compared to three days ago, although it was only a change in quantity, but the fluctuation of demonic qi alone was already about to catch up with the strength of the middle stage of the Initial Realm.

In addition, with the help of the "Fire Accumulation Technique", Lu Ling had successfully advanced to the middle stage of the Yun Qi Realm as early as yesterday, and the capacity of the fire element in his body had increased a lot, with the help of the dual power of the fire element and demonic qi, Lu Ling's current combat power was probably already beyond the middle stage of the Initial Opening Realm.

It has been less than a month since he came to the Immortal Spirit Clan, and his strength has already reached this point, if it was among the students of the Demon Spirit Academy in the past, Lu Ling's strength must have been unbeatable.

However, Lu Ling knew very well that now was not the time to be complacent, after all, this was not the Demon Spirit Academy, but the Holy Spirit Heavenly Capital, where geniuses gathered, and the strength of any young man was almost above him, not to mention the existence of Duan Yunzhou's strength that had surpassed the Initial Realm.

So he can't slack off yet, in order to catch up with the footsteps of those Tianjiao as soon as possible and gain enough strength to avenge his relatives, he must make more efforts.

Even if his opponent was the best existence in the entire Blood Demon Clan, he would not stop there.

Lu Ling took a deep breath and swept away the dark clouds that had gradually gathered in his mind, and then he stood up, stretched his body, and practiced boringly behind closed doors for three whole days, it was time to go out for a walk.

So he set his destination as Wenhai Pavilion, after all, there were many books that interested him, and by the way, he could also return the "fire storage technique" that he borrowed some time ago.

But then again, after so many days, the Nine Nights and the White Dragon Paladins haven't returned, and they don't know what mission they have performed.

On the way to Wenhai Pavilion, Lu Ling found that many young immortals who came and went all cast curious glances at him when they saw him, which made him very depressed and couldn't help but speed up his pace.

Perhaps it was because of the battle with Xiao Qi in this palace three days ago that attracted everyone's attention to him.

Moreover, after Lu Ling accidentally heard other people's discussions, he found that his identity as a demon spirit had been completely exposed.

He was starting to feel bad.

In the Demon Spirit Academy, it was precisely because of his unscrupulous use of demonic energy that he would attract the pursuit of the Blood Demon Clan, although this Immortal Spirit Palace was far safer than the Demon Spirit Academy, but Lu Ling did not dare to guarantee that the Blood Demon Clan would not secretly send someone to assassinate him.

Even in the Immortal Spirit Palace, very few people knew his identity, and it seemed that he couldn't expose the source demonic qi to others at will.

Lu Ling secretly thought, now that he thinks about it, Duan Yunzhou appeared to stop him and Xiao Qi from fighting that day, it must be because he knew the identity of his source demon body.

Although I don't know if he will be as hostile to himself as Xiao Qi, being told by someone I don't know still makes Lu Ling feel like a fish in his throat.

Dodging the gazes thrown from all directions, Lu Ling walked quickly into the huge Wenhai Pavilion. He didn't rush to the floor where the spells were placed, but went to the bookshelf where the ancient books were kept.

He had always been extremely interested in the Fairy Clan, a powerful race that stood at the top of the Hundred Spirits Realm, so he hoped to deepen his understanding of the Fairy Clan through those ancient historical books.

Similarly, Lu Ling has another purpose, which is to explore the beginning of the war five hundred years ago. He wanted to know how the Demon Spirit Clan had fallen, and although he had heard about that history, he still wanted to know more about it from the ancient records.

However, Lu Ling searched for a long time and did not see a specific record of the Great War between Heaven and Earth five hundred years ago, and most of the ancient books described that war were almost only hastily passed.

It was as if the fairy royalty was deliberately covering up that war.

Just when Lu Ling was puzzled, he suddenly felt as if several eyes were being cast towards him from a distance.

So he frowned, unhappy that even though he had found a no-man's corner, he still attracted the attention of others.

"The ......"

However, just as he put away the books in his hand and was about to turn away, a weak voice suddenly came from behind and stopped him.

Lu Ling turned his head and saw a small head popping out from behind the bookshelf, it was a girl who was only sixteen or seventeen years old, the white practice clothes outlined the girl's delicate and petite figure, perhaps because of shyness, the girl covered her face with a thick book, and a pair of big eyes were revealed under the bangs that almost covered her eyebrows.

Behind the girl, there were two teenagers of the same age standing, both of whom looked at Lu Ling with expectant eyes.

Lu Ling looked at them stunned and blinked.

The girl seemed to have mustered up her courage, and her small but clear voice was as pleasant as a clear spring.

"We'd like to ask you for a favor, can you......?"
