The Codex is recorded in the form of diaries and notes, and many of them are old man Aita's own understanding of spells, and although Merlin has mastered more than a thousand Morta words, he still feels a little difficult to read and understand the contents of the Codex.

However, this is also because there are many technical words about spells and spellcasters in the Codex, so Merlin is not so easy to understand, and as for the rest of the content on the Codex, Merlin reads it very smoothly.

Soon, Merlin found descriptions of spells, and among them was what he was most concerned about becoming a spellcaster.

"To become a spellcaster, the most basic thing is spiritual power! Only people with strong spiritual power can simulate the spell model with spiritual power, so as to engrave it in their minds and become the source of mana!"

Merlin pondered this sentence repeatedly, and although he didn't quite understand what a spell model was, he was able to grasp the meaning of the sentence in general.

Mental power is the foundation of becoming a spellcaster!

Perhaps it was because the old man Aita realized that Merlin had a spiritual power that was different from ordinary people, so he left him the ring containing the spell codex.

As for Merlin's spiritual power, it is easy to explain why it is different from ordinary people, and I am afraid that it is mostly because he is a human being in two lives.

Now that he knew that he had what it took to become a spellcaster, Merlin was also very happy, so he continued to read and began to look for a way to become a spellcaster.

Soon, Merlin found a quote from Old Man Aita on the third page of the Codex: "Mental power is the foundation of becoming a spellcaster, and the construction of a spell model determines whether the caster can become powerful or not." ”

The words "spell model" appear quite frequently in the Codex, but Merlin looked through it for a long time and found no spell model.

Now Merlin has generally understood the steps to become a spellcaster, first of all, he must have spiritual power that is different from ordinary people, and secondly, he must build a spell model, and imprint the constructed spell model into his mind with mental power, which is equivalent to using mental power to simulate a spell model in his mind.

If all goes well, then it's time to become a spellcaster.

There are several volumes of Old Man Aita's spell codex, and Merlin opened the first volume, all of which are some of Old Man Aita's experiences when he practiced spells, and did not become the most critical spell model for the caster.

So Merlin took out the second codex, and as soon as he opened it, he saw that there was a very complex pattern inside, and under the pattern, there was a note by the old man Aita.

"The spell model of the zero-level spell fireball technique, this spell model has been improved by me many times, and the characteristic is stability, although in terms of power, maybe compared to some other fireball spells, it is a little worse, but it is stable enough. As long as this spell model is used, the early casters don't have to worry too much about the problem of collapsing in their minds after the spell model is built. ”

This intricate pattern was the spell model Merlin was looking for, the spell model of the zero-level spell Fireball Spell.

In addition to this relatively stable spell model, there are also some powerful fireball models, but the old man Aita has marked under the model, if you use these particularly powerful spell models, then you must always pay attention to the problem that the spell model may collapse.

Because the structure of these powerful spell models is not stable, once these spell models are forcibly used, if they are in the mind in the future, these spell models will collapse, which will cause serious damage to the caster, and even endanger the life of the caster.

So the most important thing for a spellcaster is to build a spell model that suits them well.

Merlin didn't dwell on the spell model of the Fireball Spell, he looked down again, and found that in addition to the Fireball Spell, the Codex also recorded the spell model of the Whirlwind Spell.

However, like Fireball, Whirlwind is also a level zero spell.

There are a total of two zero-level spells, this is all the spells recorded in the Codex of the old man Aita, Merlin was slightly disappointed in his heart, there are only two zero-level spells, and they are the most basic spells.

However, when Merlin's further research became a detail that the caster needed to pay attention to, he no longer dared to underestimate these two zero-level spells.

Take the Fireball Technique as an example, although it is only a zero-level spell, its spell model is so complex that Merlin can't imagine it, and this spell model is somewhat similar to some complex mathematical models in Merlin's previous life.

Such a complex spell model, if you want to completely imprint it in your mind, and still use mental power, you can't make any mistakes at all, it's too difficult and too difficult, and it's a heavy burden for mental power.

It is no wonder that the most basic thing to become a spellcaster is that the spiritual power must be strong, and if the spiritual power is average, it is impossible to simulate such a complex spell model with mental power in the mind.

A spell model is more than a complexity, but the caster has to choose which type of spell model to use, whether it is a more stable spell model or some spell model that is particularly powerful.

Like the Fireball Technique, Old Man Aita had built no less than ten spell models by himself, each of which was very complicated, and Merlin only looked at it carefully for a while, and he felt dizzy and tired.

As for the other spell whirlwind, it was the same, the spell model was also very complicated, the two spell models, just the various models that were extended, almost filled the full thirty pages, and the second volume of the codex was almost all the various spell models of these two spells.

Merlin sat in his chair, put the spell codex on the desk, and rubbed his head gently, he was not relaxed, but quietly thought about the two spells, which spell model to choose.

"Relatively speaking, the fireball technique is more powerful than the whirlwind technique, and it is also the spell that Teacher Aita is most familiar with, my first spell should be the fireball technique!"

After weighing the strengths and weaknesses of the Fireball Technique and the Whirlwind Technique, Merlin finally settled on the Level 0 spell Fireball Technique.

Of course, there is no limit to zero-level spells, and the average spellcaster has at least three zero-level spells, because only three zero-level spells will present a relatively stable state in their minds, which is not easy to collapse, and they can also improve the level of the spell model in the future, so as to become a more powerful spellcaster.

Three spell models are the most basic, but there are also some powerful spellcasters who have four, five, six, or even more zero-level spells, but only if they have enough mental power to support them, otherwise, it is simply impossible to build more spell models in their minds.

For an entry-level spellcaster like Merlin now, his mental power is only enough to support a spell model at best.

After choosing the spell, Merlin will have to face more than a dozen spell models of various types of fireball spells constructed by Old Man Aita, which is the most troublesome thing for him.

Although the Fireball Technique was only a zero-level spell, Old Man Aita had constructed thirteen different types of spell models based on his years of understanding.

Among them, there are stable type, burst type, etc., all of which have their own characteristics.

Merlin read through Old Man Aita's spell codex again, and found that some of the most basic spell models actually needed to be modified according to their own needs.

The general framework of the Fireball model is still the same, but if some casters want to cast the fireball, the power will be greater, and the fireball released can explode and be full of damage, so it only needs to make certain modifications to the fireball model.

Some spellcasters want the spell model to be stable enough to support their promotion to a first, second, or even higher level caster in the future, so they need to make a slight change to the spell model of Fireball to make it extremely stable.

In the face of these spell models, Merlin was a little difficult, although the old man Aita also mentioned in the codex that only the spell models that he had modified himself, which fit his actual situation, were actually the best.

But Merlin is only a beginner, so what ability does he have to modify these spell models left by Old Man Aita?

Don't look at the fact that there are only a dozen spell models drawn by Old Man Aita on the spell codex, but in fact, there are deductions, calculations, etc. involved in this, and I don't know how long it took Old Man Aita, and Merlin doesn't have so much time to study these spell models slowly.

"It would be nice to have a 'matrix number'. ”

Merlin couldn't help but sigh, "Matrix" is a quantum computer, as a supercomputer with excellent computing power, the most basic matrix operations, drawing functions, data algorithms, etc. have basically reached the peak. And, more importantly, its core is intelligent, many mathematical models, physical models, etc., it can build the most perfect model according to the requirements of users.

With the "Matrix Number", no matter how complex these spell models are, Merlin can effortlessly get the spell model that suits him best.

"Do you want to activate the matrix number?"

Merlin was slightly stunned, he seemed to have heard a very faint sound just now, it was the prompt sound of activating the "Matrix".

After a while, but there was no change, Merlin could only shake his head helplessly, and muttered to himself in a low voice: "It seems that these spell models are indeed complex enough to make me hallucinate, how can I still have a matrix number?"

Merlin only thought that the voice was a hallucination caused by his mental fatigue.

Just as Merlin continued to think about which spell model to choose, suddenly, a crisp voice sounded in his head: "Do you want to activate the matrix?"

This time, the voice was very clear, constantly echoing in his mind, Merlin was slightly stunned, but he was immediately overjoyed, as if a little unbelievable.

"Could it be that the Matrix followed me here?"

Although he was puzzled in his heart, Merlin still said in a deep voice: "Activate the matrix number!"

The order was given, and Merlin waited expectantly.
