Second, Shado had temporarily left all the trivial matters outside the Mage Tower behind, and Nia had not read the intermediate arcane geometry that had been previewed.

It's been three years since the arcane competition, and Xia Duo just remembered about the new spell, the force field ball spell that was accidentally hit by the [Circular Missile].

[Magic Missile] is only a 1-ring spell, even if it is used by an archmage, it will not be fundamentally different from a low-level mage.

However, the Archmage can usually upgrade it to a 2-ring, 3-ring, or even more advanced [Magic Missile], and add more new features to it, such as locking, accelerating, exploding, and so on.

Xia Duo's [Circular Missile] is the same, before touching the second layer of the magic net, all the spell elements of the first layer are used to achieve it, and if it can be successful, it can be used to contact the second layer of the magic net, which is equivalent.

In other words, a 9-ring spell can actually be achieved only through the elements of the first layer of the magic web, but in that case, the complexity of the spell is likely to be higher.

For example, you have to continue to focus on casting spells for several years, and perform a lot of operations at the first level of the magic web, and any mistake in any step may lead to the failure of the spell.

If you can really do it, you may be able to get in touch with the ninth-layer magic net in one step. Xia Duo had never thought about it, and he would not do such a crazy thing, it was already difficult to push up 1 ring, just like that force field ball spell.

The original plan [Circular Missile] (not verified), but there was instability in the casting process, and in order not to fail, he could only play freely with his understanding of the principles of the spell, and the final result became unrecognizable.

Now what Xia Duo has to do is to completely sort out this force field ball spell, and finally simplify it (2 ring elements replace a large number of 1 ring elements, this step is the easiest), it is a real 2 ring spell.

Previously in the arena, Xia Duo had sorted out most of the key elements, as well as an overview of the spell model, and there was not much work left.

With the spell notes, Xia Duo came to the spell laboratory and applied to Ta Ling for the 2-ring level magic net suppression effect, he didn't want any accidents during the experiment.

"Not bad!" After feeling the magic net environment in the spell laboratory a little, Xia Duo nodded with satisfaction, worthy of its price of 60 gold coins for 1 hour!

At the beginning of the experiment, Xia Duo did not experiment with the force field ball spell first, but first tried the original version of [Circular Missile], and if it was successful, there would be another 2-ring spell.

However, two successive force field explosions made him understand that the [Circular Missile] was indeed still immature, and if it wasn't for the spell laboratory, he might have been injured.

Think about that force field ball on the field, it's really a fluke! As long as the spell laboratory is activated, it is at least 1 o'clock, and there is no situation where it is turned on when casting spells and closed when thinking, but it is also this feeling of burning money at any moment that makes Xia Duo feel that the spark of his thinking is also burning.

Even his memory was much clearer, which saved him a lot of effort in completing the elements of [Force Field Ball].

…… At noon, Xia Duo hurriedly had lunch and went back to the spell laboratory, his experiment had reached a critical moment, the spell elements and spell structure had been completed, and he was now conducting a stability test.

A spell is not only a successful spell, but also cannot be too variable, and the factors that affect the stability of a spell can be roughly divided into two categories: the caster's own reasons, and the spell's own reasons.

The former is not considered for the time being, and the latter is mostly a conflict between spell elements, similar to redundant components in a computer program, which may or may not affect the effect of spells.

But for the sake of more stability, it is still necessary to eliminate as much as possible. If you want to check the redundant elements of the spell, in addition to slowly testing it through the stability test, the most direct way is to start from the essence of the magic net and the principle of the spell, and use theory to guide practice.

In this regard, Xia Duo is still lacking for the time being, and he is not as proficient as he is at the 0 ring level, but practice itself can also promote theoretical progress, and he is now brushing theoretical experience in kryptonite.

There is an old saying in Xia Duo's hometown,

"What you get on paper is shallow", it is very empty to think about theory, and combining theory with practice and impartiality is the right way.

One hand is the essence of the magic net and the principle of spells, and the other hand is spell casting training and application practice, grasping with both hands, and both hands must be hard.

…… Returning to the spell itself, this new spell, which had been named [Imprisoning Magic Ball] by Xia Duo, finally took shape after more than ten experiments.

The specific effect of the new spell is a force field ball that quickly envelops and imprisons a solid object when it comes into contact with it.

It can not only be put on the enemy's head, but also on the hands and feet, weapons, although it is not a direct lethal spell, but Xia Duo is quite optimistic about its application.

This is a 1-ring manifestation of a 2-ring spell, simplifying it to a true 2-ring spell, and at this point the [Imprison Orb] can be considered a successful development.

But Xia Duo still has some regrets, he needs more tests, such as cast range, imprison strength, reaction to [Mage Armor], and so on.

It's just that the spells he can use are extremely limited, and he is not allowed to conduct endless experiments at all, and at this moment, he can't help but think of the benefits of recruiting apprentices.

The apprentice cooperates with the mentor experiment, which is essentially a joint spell cast led by the tutor, which is more labor-saving than the tutor casting alone.

However, the Tower of Time can only recruit apprentices for mid-level mages, and there must be apprentices, not every year there will be new mages.

Even if you have, you have to talk about seniority, and you don't know when it's your turn! Alas—Xia Duo sighed, feeling a little too optimistic, and he should be worried about when Nia will catch him for experiments!

…… With only the little energy left over for making scrolls in the evening, Xia Duo was not ready to try anything more, and the afternoon became very leisurely.

He took out the "Intermediate Arcane Geometry" he borrowed before and began to preview, although it was placed in the middle level area of the library, but in fact, most of the cases in it were still 1-ring spells.

However, starting from intermediate arcane geometry, it is no longer limited to analyzing spells, but analyzing the magic web, which involves the essence of the magic web.

If the principle of magic is engineering, then the essence of the magic web is natural science, and this "Intermediate Arcane Geometry" already has a bit of the flavor of "Mathematical Principles of Natural Science".

Xia Duo read it greedily, and when he encountered something he couldn't understand, he jumped over it temporarily, trying to read it as quickly as possible, and first have an overall understanding of it.

But when he turned to the last page, a line of text on it made him a little dumbfounded-

"To be continued."
