The Dark Spirit Domain returned to calm, but the departure of the ninth-level spellcaster still caused a lot of discussion, maybe others didn't know what it meant, but Merlin, who had personally experienced Black Sand Castle, deeply knew how serious this matter was.

"The ninth-level spellcaster has been invited, and the three large spellcaster organizations have signed a contract, this is to really do something to Osmu, and it is also the power of almost all the potential forces of the entire southern spellcaster world!"

Merlin knew very well that even small spellcaster organizations such as the Dark Spirit Domain were invited, so it was obvious that these were the three major spellcaster organizations ready to start.

Osme can fight against almost all large spellcasters, although he has great strength, but the deeper reason is that Osmu's lair is really very secretive, even if the large spellcaster organization wants to destroy it, it can't find a place.

This is a little different from the Dark Spirit Domain, but the Dark Spirit Domain can also use means to kill the members of the Dark Spirit Domain, snatch the Dark Spirit Ring, and then you can forcibly enter the Dark Spirit Domain. Osmu, on the other hand, no one knows where its lair is, which is very mysterious.

But this time it was different, the Black Sand Castle got the location of Osmu's lair, and perhaps it was because of this that Osme was desperate to send a spellcaster led by the Black and White Archmage to disturb the Black Sand Castle.

It's a pity that the Black Sand Castle also has hole cards, and it is a powerful guardian spirit, and the black and white archmage is not an opponent.

"Chaos is coming, we need to speed up and increase our mental power!"

Merlin is back in the Tower, this time. He was frantically preparing potions almost day and night. And as Merlin became more and more proficient in the heat of the potion. The success rate of his preparation of the Mokora potion is also getting higher and higher, from the original thirty percent to nearly forty percent.

Merlin was overjoyed by such a high success rate, the Mokora Elixir was very precious, and although its effect had decreased now, it was still much more effective than Bell Space and other potions.

He was able to concoct several Mokora potions almost every day. Later, it will take a few days to take the magic cora potion to increase mental power.

Therefore, Merlin's spiritual power quickly increased from the early stage of the fifth level to the middle of the fifth level, and even continued to grow, gradually reaching the peak of the fifth level.

At this time, more than a month had passed, and Master Delmar had never returned. Moreover, the entire Southern Spellcaster World Realm seems to be calm.

But Merlin was clear. Behind the calm, there must be a huge storm brewing.

"Five-level peak, you can try to build a fourth-level spell!"

Merlin finally stopped concocting the Mokora Elixir, and now he had almost consumed half of the Mokora Potion, and his mental power had reached the peak of the fifth level.

If you want to improve your spiritual power from level five to level six, it requires a lot of accumulation, and it is impossible to do it in a short period of time, so Merlin did not continue to prepare the magic cura potion, but chose to build a spell.

With Merlin's current level of mental power, it is not difficult to construct a fourth-level spell, you can build several fourth-level spells, although it is unlikely that all the six spells will be successfully constructed, but there is still no problem with the most powerful fourth-level spells.

The difference is that the fourth-level spells that need to be constructed are ordinary fourth-level spells, or whether they use the matrix number and the amount of power consumed by the fire law to derive a new fourth-level spell.

"Matrix number, call up the new fourth-level fire spell model deduced!"

Merlin directly activated the matrix number and began to check the more than two hundred fourth-level fire spell models that he had deduced from the matrix number by consuming some fire laws at the beginning.

Originally, because of his lack of mental power, Merlin did not build this fourth-level fire-based spell, but now it is different, Merlin's spiritual power has reached the peak of the fifth level, which is enough to build several fourth-level spell models.

Among the more than two hundred spell models, most of them have a very high fit, at least more than ninety percent, and even a few have a hundred percent fit.

The biggest difference between the derived spell model and the ordinary spell model is in the fit, and a new spell model can be deduced according to the previous spell models, and the fit can reach 100%.

Merlin now has to choose a spell model that is 100% compatible, and only such a spell model can really exert its full power.

Merlin carefully examined the fire spell models he had previously constructed, the zero-level spell Fireball Spell, the first-level spell Raging Flame, the second-level spell Purgatory Fire, and the third-level spell Condensed Fire.

Except for the fireball technique, which is relatively ordinary, the other spells are very complex, and all of them are offensive spells, and their attack power is the best among many spells.

According to this way, the fourth-level spell that Merlin wants to choose has to be a spell that is very violent and has a very powerful attack power, and the fit is also quite high, such a spell, Merlin only found two out of more than two hundred spell models.

Then, after careful selection, Merlin finally chose a spell model, which was derived from the matrix number, which was 100% compatible with the spell model that Merlin had built before, and the power was even more amazing.

Such a powerful spell model should be very complex and very difficult to build, but the newly derived spells are not like this, and the spells deduced by the caster himself according to the actual situation are very convenient to build, and the difficulty is reduced a lot.

Basically, as long as you can deduce a new spell by yourself, and your mental power is sufficient, then you can basically successfully simulate the spell into the sea of knowledge, which is very simple, which is also one of the benefits of the deduced spell.

Now that he had chosen his spell, Merlin began to mobilize all his mental power and concentrate on simulating the first deduced spell model.

Time passes little by little, although the deduced spell model is easy to simulate, but after all, it is too complicated and takes a long time.

"Boom".

I don't know how long it took to say that Merlin's sea of consciousness shook violently, and a huge spell model appeared in the sea of knowledge, and countless fire elements frantically entered the new spell model, which was quickly transformed into mana.

"Finally it worked! First fourth-level spell!"

Merlin felt that the current sea of consciousness seemed to be full of burning flames, and compared to the spells below level four that had been constructed before, the fourth-level spells were really very different.

With only one fourth-level spell model, its power is almost as powerful as all the spell models that have been built before, not including Pandora's magic energy, of course.

The fourth-level spell is a qualitative improvement, and Merlin can clearly feel that the fourth-level fire spell that has just been constructed has formed a huge suppression on the other spell models in the sea of knowledge.

"How about trying it out?"

Merlin took a deep breath and felt that some mana had accumulated in the spell model, so he stimulated the spell model with his mental power and released the spell in an instant.

"Boom".

The flames in the sky faintly descended and enveloped the entire room, and everything that the flames touched was reduced to ashes.

"It's so powerful! The power of the spell alone is comparable to the power of an ordinary sixth-level spell!"

Merlin was pleasantly surprised to see that the power of the deduced spell was so terrifying, and he also noticed that the function of releasing three spells in his body, and forming a strengthened spell, disappeared.

The enhanced version of the spell, in fact, after Merlin cultivated a powerful magic energy, it was rarely used again, and Merlin did not know the enhanced version of the spell before, what caused it, and why there would be an enhanced version of the spell.

And now, Merlin is gradually clearing.

That's because the previous spells were not 100% compatible, and they could never reach the point where they were most compatible with the caster, so the power of the spell could not be maximized.

In the past, the enhanced version of the spell actually helped Merlin to bring out the true power of the spell, but now, the new spell deduced by the matrix number is processed with data integration, and the fit is almost 100%, and it has reached the point of perfect fit.

Therefore, the fourth-level fire spell built by Merlin can actually exert its full power at any time, so naturally there is no enhanced version of the spell, because it itself is already the ultimate in the power of the spell.

"I didn't expect that the deduced spell could burst out with all the power of the spell! Since the spell burned everything in the room to ashes, and the power was huge, then this new fourth-level spell was called Ash Fire. ”

Merlin named this new fourth-level spell, and since then, there has been a new fourth-level spell in the world, called Ash Fire!

Even in the future, Merlin will be able to pass on the ashes and become a powerful spell unique to the Wilson family!

After checking the power of the ash fire, it is indeed very powerful, comparable to ordinary sixth-level spells, but the power of spells alone is naturally far from enough, and there is also magic energy!

Fire magic energy, at present, Merlin only has the fire of dismemberment, and the power of the fire of disintegration is indeed quite powerful, although it can't be the magic energy of fusion spells, but it is suppressed by the law of fire, forcibly integrated into the fire spell, and it also exerts a very powerful power.

Now Merlin just wants to try to see if he can smoothly integrate the extinguishing fire into the new fourth-level spell he has constructed, the ash fire.

This kind of attempt is very important, and once successful, the power of the ash fire will be increased several times!

Thinking of this, Merlin did not hesitate any longer and began to control the extinguishing fire.

"Fusion!"

Merlin immediately tried to merge the extinguishing fire with the ash fire. (To be continued......)
