Exploring fire-based runes was even faster than Ron had expected.

On the one hand, his spiritual power has reached the level of 45 points, and he can almost continuously try rune deduction, and the spiritual power consumed is negligible, and the normalcy can be restored.

On the other hand, with his previous experience in deducing wind runes, Ron basically knew how to avoid some of the more obvious mistakes, and it was tantamount to getting straight to the point.

In just three days, he had mastered two fire-based runes.

However, what made Ron a little speechless was that these two derivative runes with the base runes, no matter how they tried, they would fail to combine and could not form second-order fire-based magic.

Bang!

The three runes vanished, and a small flame surged into the void, bursting like fireworks, and then dissipated in the sea breeze.

"The last combination also failed."

Seeing this scene, Ron showed a touch of helplessness, he didn't expect to make two fire-based derivative runes, but he still couldn't combine the second-order magic of the fire-based system.

Then it seems that the second-order magic of the wind system should be his luck, and he just got the derivative rune that can combine the second-order wind magic, and now he is not so lucky when exploring the fire system.

"Then there will be one more."

Ron let out a sigh, a little helpless, but now he could only explore the third fire-type rune.

Fortunately, he is now more and more proficient in the deduction of runes, even if he gets all the eight derivative runes of a certain department, it will not take half a month, anyway, these are things to be done sooner or later, so it is regarded as being done in advance.

What made Ron a little unexpected was that on the morning of the fourth day, when he deduced the derivative rune for the seventh time, he successfully found the third fire-type derivative rune.

It's not about experience, it's just about luck.

"Luck always goes up and down."

Looking at the third fire-based derivative rune that emerged from the Elven Orb at the top of the Elven Wand, emitting a golden light, Ron's mood couldn't help but feel a burst of joy.

This is a surprise as soon as I woke up.

Moreover, the scientific and reasonable cultivation in the past three days has also increased his spiritual power by about 1 point, almost to 46 points.

For the current Ron, he has long been able to accurately locate the amount of mental power of 1 unit, after all, he has used achievement points to improve so many times back and forth.

Even if the achievement system screen does not show the total stats, only the increase caused by the achievement points, he can know exactly what the total stats are.

"So...... The combination that exists now is ......"

Ron pondered for a moment, weaving out in his mind the combinations that the four runes could form, and then put aside everything he had tried before.

After a round of analysis and screening, the remaining combinations were quickly reduced.

On the basis that at least one basic rune must exist, and no combination of the third derivative rune has been tried, then there are actually only four remaining combinations, that is, when the basic rune and the third derivative rune are combined, and then the basic, first, second, and third runes are combined one by one.

Ron took a look, and there was no shadow of Cocosia Village in front of him, thinking that it should be too late, so he quickly threw himself into the combination attempt.

Base, Base, Third Rune Derivation......

Tried five times, confirmed to fail.

Basic, first, and third rune derivations......

Tried four times and confirmed failure.

Failing two rounds in a row made Ron a little helpless, so that the four runes couldn't combine a fire-based second-order magic, it would be a bit too much.

And the point is, the shadow of Cocosia Island can already be faintly seen in front of him, and it is estimated that he will be there in another hour or two, and he will have to adjust his condition before then.

"After an hour or two, it's enough to try the remaining two."

Ron exhaled, regained his mental state a bit, and then tried again, trying a third combination.

It doesn't matter if he fails, with the second-order wind magic, it is enough to kill Ah Long in an instant, but he is a little unhappy that he spent a lot of time on fire magic and didn't get results.

Airplanes.

Three points of golden light emanated from the chaos inside the Elven Pearl, and quickly extended lines to the surroundings, intertwined and combined.

The basic runes of the fire system and the third and fourth derivative runes were different from each other, but at this moment, after extending the lines and interweaving together, it seemed to form a complete whole, seemingly without any flaws, as if forming a larger rune.

"It worked!"

The moment the rune was formed, Ron knew that he had succeeded, and his eyes lit up, revealing a hint of excitement, and without hesitation, he manipulated the magic to smash it into the sea.

Rumble!

The runes in the Elven Orb flashed away, and the fire element between heaven and earth instantly condensed, forming an arrow of flame in the void and shooting towards the sea.

The size of this flame arrow seemed to be even smaller than the fireball technique, but its flight speed was comparable to that of wind magic, and when it landed on the surface of the sea, it exploded with a bang, turning into a huge flame that swept in all directions, completely enveloping a radius of several meters.

As the flames exploded, a system prompt rang in Ron's ears.

[Hint: You have mastered the second-order magic of the fire system, the Flame Burst Technique]

"Flame blasting, not bad."

Looking at the power of the Flame Explosion Technique on the surface of the sea, Ron couldn't help but admire, the power of this move on a single body is probably greater than that of the Gale Slash!

Although the Gale Slash is also terrifying, it is a range of skills after all, and this flame blasting technique is like a bomb, condensing the flames at one point, and then exploding after hitting, and the power on the single body should undoubtedly be above the Gale Slash.

In terms of area damage, it is inferior to Gale Slash, after all, the area damage of the Flame Burst only appears after the flames explode, and it seems to be only the impact damage of ordinary flames, which is similar to the Fireball Technique.

And the key point is that the speed of this flame explosion spell is extremely fast, not slower than wind magic, so it does not need to rely on combining with wind magic to play an effect, it can be released as an extremely strong single magic in itself.

After judging the advantages and disadvantages of the Flame Burst, Ron nodded in satisfaction, and then began to practice the magic of Flame Burst, ready to master it.

For him now, it doesn't take a long time to master a magic spell continuously, even if it's a second-order magic, as long as he releases it four or five times, the release speed can easily be reduced to less than a second.
