Fourth-level spellcaster, that is a watershed, if it is in the dark spirit realm, it means that he has been able to build a tower on his own, can teach students, and become a senior mage on the path of the caster!

And for Merlin, the benefits he felt as a fourth-level spellcaster were far more than that, the moment his last two fourth-level spells were successfully constructed, there was a trace of fluctuation in the entire sea of consciousness, and the originally extremely inclined spell model instantly regained its balance, just like a lake, extremely calm.

The spell model in the entire sea of knowledge has formed a whole, which has greatly released the spiritual power, and with the current spiritual power of Merlin, he can even try to build a fifth-level spell!

Moreover, Merlin also found that he now released the spell, and it seemed that he had a very mellow feeling, fire, wind, ice, earth, thunder, and darkness, these six elements, all madly drilled into Merlin's body, and Merlin's body, like a black hole, was frantically devouring these elements.

After being promoted to the fourth level, all the spell models in Zhihai have undergone subtle changes, and it seems that they can hold more mana, expanding the limit of the spell model, which is not unique to Merlin, but a change that all fourth-level spellcasters will have.

It is no wonder that those fourth-level spellcasters are fundamentally different from those below the fourth level, after being promoted to the fourth level, their strength has immediately increased several times, and in all aspects, they far surpass those casters below the fourth level.

After Merlin became a level 4 spellcaster, he did not immediately build a level 5 spell, although after becoming a level 4 spellcaster, due to the balance of the spell model. Unleashed a lot of mental power. Allowing him to construct a level 5 spell. However, once the fifth-level spell is constructed, the spell model in Zhihai will be out of balance again, and a large amount of mental power will be consumed to stabilize the spell model.

At that time, it is difficult to say whether there will be mental power to stimulate spells to fight, and mental power is crucial, although it usually seems to be inconspicuous. But if you don't have mental power, then it will be a problem for the caster to even cast spells.

Because, when the caster releases a spell, he is actually using mental power to stimulate the spell model, thereby releasing the spell.

After being promoted to a fourth-level spellcaster, Merlin began to cultivate the special magic energy Ice Realm, and now he has built a fourth-level ice spell Extreme Ice Domain, and he can better cultivate the Ice Realm.

The biggest difficulty in cultivating the Ice Realm is to transform the body, which is a life of death. Very difficult, most of the casters. None of them can transform the body successfully.

Cultivators of special magic energy have to go through the level of transforming their bodies, and if they succeed in transformation, they can cultivate special magic energy and have strong power, if they fail to transform their bodies, they can only face death.

Merlin relied on the terrifying recovery power of the mysterious relief posture to successfully transform his body, so there was no longer any difficulty in cultivating the Ice Realm now.

"Buzz".

Merlin's body, a mysterious symbol emerged, this mysterious symbol, flashing with an icy aura, chilling, endless ice elements, seemed to be converging towards Merlin's body.

The first step of the Ice Nation is to successfully portray the mysterious symbols, and the next step is to stimulate the symbols with spiritual power, so as to make the Ice Nation descend according to the methods of the Ice Nation.

"Boom".

Merlin's spiritual power was already strong enough, coupled with the success of the portrayal symbol, as soon as his spiritual power was stimulated, the cold feeling appeared again, and invisibly, a cold space suddenly descended.

"Click, click, click".

Merlin was in the very center, so he could naturally feel the invasion of the extremely cold qi, but his body was already able to withstand the invasion of the extremely cold qi, and he could even feel a trace of closeness.

The invisible freezing force shrouded an area, Merlin knew that this was the country of ice, if it was shrouded in it, he could freeze with a single thought, setting off a cold ice storm, and endless ice elements would be raging.

This is the horror of the Ice Country, once the Ice Country comes, the casters who fall into the Ice Country will be suppressed, and sometimes they will not even be able to exert half of their strength.

The main role of the Ice Nation is to suppress, restrict, and bind!

However, this is only the first form of the Ice Realm, and the amount of restraint is not too strong, and the extent to which ordinary level 7 spellcasters are weakened is not very large.

The Ice Realm also has seven forms, and as the magic energy of the Ice Legend, the power is naturally strong, but it is not so easy to cultivate to the second form, the third form, or even stronger.

Merlin's Dark Eye is because Mage Leo had already cultivated to the fourth form, but he only sealed it in the third form and the second form.

Later, it was transferred to Merlin, so Merlin was able to directly cast the power of the third form of the Dark Eye, and even in the future, if Merlin could withstand the backlash of the Dark Eye, he could also directly cast the power of the fourth form of the Dark Eye.

But the Ice Realm is different, Merlin needs to cultivate step by step, starting from the first form, and the cultivation of the Ice Realm, like other special magical abilities, requires the comprehension of "ice".

Merlin's comprehension of "fire" is deep enough, he has a fire law, and he always has a deep understanding of "fire", but for ice spells, Merlin is no different from beginners.

If it really depends on him to comprehend the essence of "ice" in order to raise the ice country to the second and third forms, I am afraid it will not take long for the real sea bream.

Years, even decades, such a long time, wouldn't Merlin's Ice Nation be of any help to him?

Thinking of this, Merlin was naturally a little unwilling in his heart, but when he felt the Law of Ice suppressed by the Law of Fire and his spiritual power, Merlin moved in his heart.

If it is the comprehension of "ice", no one has a more profound law of ice, this is the strongest law of the legend of ice, the most powerful amount of a certain element!

So, Merlin Shi exhibited the Ice Country, and suddenly, the invisible Ice Country came, this is only the first form of the Ice Country, shadowless and invisible, and the scope is also very small, and the power is naturally not very powerful.

When the Land of Ice came, Merlin violently used all his strength to "drive" the Law of Ice with the Law of Fire, and entered the Land of Ice.

"Boom".

With the gradual integration of the law of ice into the country of ice, the entire country of ice is rapidly transforming, the law of ice is the strongest way of the legend of ice, the comprehension of ice, has almost reached the extreme, so the country of ice is rapidly transforming.

The originally invisible Ice Country began to gradually become a little transparent, which can be slightly detected with the naked eye, this is the second form of the Ice Country, Merlin can clearly feel that the binding force of the Ice Country has become stronger.

However, the Ice Realm continued to transform, and soon transformed into translucent, and the naked eye could clearly see the situation of the Ice Realm, which was like a world of ice and snow, with an extremely cold aura floating in it, and the power of restraint was very strong, capable of suppressing any spellcaster.

Even the power of special magic energy can be weakened in the Ice Country, this is the third form of the Ice Country, Merlin can clearly feel that the ice mana is consumed very quickly, as if it will not last long, it will be consumed.

This is already Merlin's limit, the third form of the Ice Country!

"Close!"

Merlin immediately drove the Law of Fire and drove the Law of Ice out of the Ice Realm again, and without the Law of Ice, the Ice Nation also stopped its metamorphosis.

"Third form!"

Merlin's Ice Nation had finally stopped its metamorphosis, and he was now able to maintain the Ice Nation Third Form for about an hour, which was a long time enough to kill any enemy.

Of course, this is also Merlin's limit, if it is the fourth form, Merlin can't support it at all, maybe the mana will be sucked out of the first time, the spell model will collapse, special magic energy, every time a form is raised, it is very terrifying, almost all of it is a qualitative improvement.

From the first form to the third form, Merlin only took a short time, this is not Merlin's cultivation, but a trick, it was he who used the law of ice to "deceive" the country of ice, and used the law of ice to elevate the country of ice to the third form.

However, only a caster like Merlin, who accidentally obtained the Law of Ice, and a caster of the Ice Realm who can cultivate, can "take advantage of it", and without either of these two conditions, it is impossible to succeed.

Basically, Merlin is also the only one who relies on the law of ice to "trick" cultivate the Ice Nation to the third form.

"It turns out that the law of ice can still have such an effect, so it has to be preserved. ”

Merlin didn't expect that this law of ice, which was forcibly suppressed by the law of flames, seemed to disturb the law of knowing the sea at any time, and had such a function, it could quickly cultivate the law of ice, so it was possible to keep the law of ice without consuming it, and if Merlin reached the condition of cultivating the fourth form of the ice country in the future, he could use the law of ice to cultivate the ice country.

The Ice Country is now translucent, which can cover a range of hundreds of meters, and Merlin can also be further condensed to reduce the coverage of the Ice Country, but this requires the mobilization of a huge amount of spiritual power, and the Ice Country will be further enhanced after the coverage is reduced.

After successfully cultivating the Ice Realm, Merlin also opened his eyes, he had been with the Frost Lord for three months, and he could put his cultivation on hold for a while.

Merlin got up, pushed open the door, and walked out peacefully. (To be continued......)
