After adjusting to the main body for a few activities, Xia Duo started casting spells directly under the light ball in this projection hall. This is why he, as the tower master, has such authority.

Others, even Ebbock, cannot cast spells here at will.

The spell that Xia Duo chose to break through the fourth layer of the magic net was [Mage Armor]. As a mage, his own protection cannot be overstated.

The [Mage Armor] below 3 levels is sufficient for ordinary people, and the mage can not only face ordinary people, or that only the mage can be the opponent of the teacher.

In the past, Xia Duo upgraded the [Mage Armor] from level 1 to level 3. The only idea was to increase the strength of the force field. For example, at level 1, the [Mage Armor] could not even resist the cutting of sharp swords. Buffer a little bit.

But by the 2nd ring, it can resist the arrow shot, and by the 3rd ring, ordinary people's attacks can basically be ignored.

For the 4-level [Mage Armor], Xia Duo's idea is to integrate other protection spells, such as more targeted [protection against energy damage], [resistance against energy damage], and even a further element balance field.

In the projection plane before, Chateau had already made a complete 4-ring plan, so the first time he came out, he would use this to contact the fourth magic net.

The 1st ring [Mage Armor] has only 18 basic elements (including 12 on the surface of the magic net and 6 on the first layer of the magic net), which means that you only need to perform 18 specific operations on the string of the magic net to successfully cast Come out of the 1st ring 【Mage Armor】.

The 2nd level [Mage Armor] has 36 basic elements (surface layer 12, first layer 12, second layer 12), the difficulty of casting spells is greatly improved, but these elements are not irregular, and the structure of the spell comes from a certain sense In other words, it is the law, and it is also a method to assist memory.

At the higher level of the spell structure, various spells, gestures, graphics, etc. can also be used for auxiliary memory. Only by taking a multi-pronged approach can all the elements of a spell be remembered.

The higher the spell level, the more constituent elements. Generally speaking, the shallow elements of the magic net can be replaced with fewer deep elements, and vice versa.

But if a 9th-level spell is expressed in shallow elements, it may be an astronomical number. Even in theory, a beginner wizard can cast a low-level spell equivalent to the 9th-level spell, but in practice, it may It's not that ideal.

Of course, if it is really released, then this junior mage can also use this spell to see the nine-layer magic net in one step.

In fact, Xia Duo has never heard of such a mage. Even if there is, without theoretical knowledge, he is just an exquisite toy with no practical value.

More likely, he accidentally drove the string of the ninth layer of the magic net and ended up playing himself to death.

At present, Xia Duo can only break through the magic net layer by layer. He has never thought of reaching the sky one step at a time. He dares to advance as much as he has the theoretical foundation!

[Mage Armor]’s 4-ring plan was developed by him in order to reach the fourth layer of magic net, because there is no fourth layer element, so it needs to be replaced with a lot of shallow elements.

If it is not for a full understanding of the nature of the magic net and the principles of magic, no one would dare to play like this.

There are close to two hundred basic elements, of which the most used is the third layer of the magic net string, which accounts for almost half of all the basic elements.

This kind of complicated intermediate transition spells doesn't need to be all in mind. In fact, Xia Duo started casting spells on the arcane geometry in the spell notebook before him.

If it is an ordinary note, you need to constantly turn pages in the middle, and this is based on the solid "Arcane Geometry" foundation.

In the process of casting spells, Xia Duo had practiced on the projection plane many times, but he could not reach the next layer of magic net there before he came back!

"Om--" An invisible armor appeared on Xia Duo.

Thanks to the study of "Arconic Principles", Xia Duo has a deeper understanding of energy. In addition to absorbing certain energy damage, this 4-ring solution also optimizes the original spell structure to make this thin layer. The protective force field becomes stronger.

This is similar to the iterative upgrade of technology, even the previous low-level [Mage Armor] can benefit from it!

And at the moment when the spell succeeded, Xia Duo's consciousness was elevated instantly, not a kind of substantial elevation similar to astral projection, it was an elevation of vision and cognition.

At that moment, he saw the essence of the magic net from a higher perspective-a magnificent and energy-filled complex structure, all over the world.

He himself, as well as the Tower of Time he is in at this time, exist in this magnificent structure, the strings of the magic net connect everything and interweave with each other.

In the next instant, Xia Duo's consciousness fell into a mortal again, all the previous ones disappeared, only the fourth layer of the magic net had opened his arms to him.

However, Xia Duo didn't want to experiment with the fourth layer of the Magic Net at this time. He just wanted to know if the projection plane was still there!

"Taling, does the projection plane that we searched for still exist?"

"Xia Duo, the substitute, 10 seconds ago, the projection plane No. 2 disappeared."

Ten seconds!

Chateau still deeply remembered the situation before the projection. After being reminded by Taring, he sent it to the projection hall to perform the projection without any hesitation.

After coming back, he executed the 4-ring scheme for the first time, but I didn't expect it to be a step too late. The most time-consuming process was his casting process ~lightnovelpub.net~ about 20 seconds.

With this calculation, the projection plane only existed for about 10 seconds. (The main plane time)

Before the projection plane disappeared, Xia Duo was a little disappointed, but subconsciously, he still gave birth to a sense of relaxation from the heart.

The next moment, a burst of fatigue hit, Xia Duo thought of the last time he performed the astral projection and then slept all day, and besides this, there may be traces of time that need to be paid attention to.

He told Taring to transport himself back to his residence, and fell asleep after touching the bed.

...

the next day.

Xia Duo woke up from a deep sleep, stretched lazily, and when he opened his eyes, he saw the familiar roof of the Tower of Time, and what he felt physically was not soft compared to the tree house. How many times the bed.

"That's right!" Xia Duo jumped up from the bed suddenly, he untied his clothes, summoned a water mirror, looked at the mirror, and tried to recall his figure "a year ago".

After returning to the main plane for more than a year, all these times will be fed back to the body, but the consciousness has been far away from the body for a long time, making him a little fuzzy on the details of the body.

It is really hard to see the traces of time in one or two years.

There is also the influence of bloodline. After the bloodline is awakened, the effect of age on the appearance becomes smaller. This is somewhat similar to that of an elf. An ordinary elf can live for hundreds of years, but will only grow old quickly until the end of life.

Xia Duo suspected that the Awakening Bloodline had become a longevity to some extent, but it was a pity that he had not read a book about the lifespan of the Bloodline Warlock in the Tower of Time.

Otherwise, he can use the projection plane more boldly to get the effect of nearly time acceleration.
