With the assistance of learning scrolls, coupled with Xia Duo's previous understanding of the essence of the 0 ring spell, the [Secret Law Mark] is not a problem at all.

The so-called [arcane mark] is to leave a personal mark on the body of an object or creature, which can be a text or a figure.

The most important thing is that the [Arcane Mark] can be used for the positioning of some specific spells, such as [Communication], if there is no [Arcane Mark] to assist in positioning, then the target must be within the caster's line of sight, and the distance is relatively short.

After a brief study, Xia Duo understood the existence principle of the [Arcane Mark] and the details of the casting, and also discovered the difference between the magic of the [Arcane Mark] and other 0-ring spells.

In short, the other 0-ring spells that Xia Duo mastered, such as [Light Technique], [Acid Splash], or [Illusion Technique], [Mage's Hand] and the like, seem to have a duration, but they are only one-time magic effects.

However, once the [Secret Seal] is formed, it can exist for a long time, or even permanently.

This can't help but remind Xia Duo of a very clever magic technique, [Magic Constancy], but [Magic Constancy] can always maintain a magical effect, while [Arcane Mark] can only keep a mark without a magical effect.

However, Xia Duo speculated that the [Secret Law Seal] might be an initial stage leading to the [Magic Constant Technique], but unfortunately it could not be verified at this stage.

……

It wasn't difficult to cast the [Arcane Seal], and it only took a little practice for Xia Duo to leave a smile on the handle of his new dagger.

While in the cast focus, this symbol is linked to the "wisps" structure of the magic web, emitting a faint magical aura, and once exiting the cast focus, the smiley face symbol disappears.

After that, Xia Duo cast the [Arcane Mark] again, leaving a triangular mark in the palm of his left hand, and this time he chose to make this triangular mark visible.

It can be seen without entering the cast focus state, and even ordinary people can see it, similar to the portrait behind the badge obtained earlier.

Of course, when he entered the state of casting concentration, Xia Duo could still see this mark emitting a faint magical aura.

This constant state of the [Arcane Seal] is not directly related to what the mark looks like, but to the elements of this magic.

There are only 12 elements to cast the [Arcane Seal], and through these twelve most basic "actions", the operation of the magic net is completed, but through these operations, the spell structure on top of the elements forms a cyclical state.

As for the other 0-ring spells known to Shado, their spell structures are all in an open state.

Because the essence of magic is the operation of the magic net, there is an operation, and the magic net will naturally have feedback. The spell structure in the open state is always in the confrontation with the trend of the magic web restoration.

However, the spell structure in the cyclic state seems to have become a state of symbiosis or parasitism with the magic web, and as long as the magic net does not appear abnormal, the cyclic state will always exist.

This is probably the reason why the [Arcane Seal] can be preserved for a long time.

In an instant, Xia Duo thought of too many things, and he couldn't wait to immediately turn into a Grand Arcanist and start verifying them one by one.

But it wasn't the sound of human voices and weapons clashing from the camp that made Xia Duo realize his situation - he had to survive this orc tide first.

[Arcane Mark] Xia Duo has fully understood, but he is not very proficient when casting spells, but the [Arcane Mark] itself does not need to be very fast or in quantity, as long as it can be used.

On the contrary, it is a key spell like [Communication Technique] that needs to be practiced a lot, otherwise when the enemies all rush to the front, the news has not yet been sent, and the picture -

Xia Duo couldn't imagine it.

Fortunately, I have already understood the principles of spells, and I only need to improve my proficiency when practicing, so that practice makes perfect, this is water milling, there is nothing to please.

When people are concentrating on one thing, time always passes quickly, and in the blink of an eye, the light in the room has dimmed, and the sound of drills outside has gradually subsided.

Xia Duo rubbed his sour eyes, and was about to get up and move his hands and feet, when the voice of the big Jesse came from outside, "Master Xia Duo, the captain asked me to inform you that it's time for dinner. ”

"So fast?"

Xia Duo walked out of the room in two steps, just in time to meet Jesse who was about to knock on the door, "How was the afternoon training?" Is Ava back? ”

"It's quite smooth, except for Yidim, everyone else has combat experience, and they only need to be familiar with some army formations and routines. As for Ava—"

Jesse also showed a dissatisfied look, "After he came back, he talked to Captain Gibb for a while, and then disappeared again, and the captain said that he was going to inquire about the news, and I didn't dare to ask more, why don't you ask the captain, Master Chardo?"

"Hmm."

Xia Duo nodded and agreed, Ava's affairs must be asked, otherwise such a maverick player will always be a problem.

……

After dinner, Shado approached Captain Gibb and told him about Ava, who was not surprised by this, and explained Ava's actions today.

"Ava has been professionally trained and is an excellent wanderer, he is going to Mission 12 to investigate the situation today, if he is placed in formation to fight the orcs head-on, it can only be said that it is the loss of our team."

"Hmm."

Xia Duo nodded, but he was not satisfied with this answer, what he cared about was not what Ava's responsibilities in the team were, but that Ava always disappeared without saying a word, which made him very uneasy.

And he felt as if Gibb was hiding something from him.

Xia Duo stared at Gibb with burning eyes, as if if he didn't say anything, Xia Duo kept staring like this, Gibb was silent for a while, and after all, he still couldn't say what Xia Duo wanted to know.

"Master Shado, please don't ask about Ava, I can guarantee with my life that Ava is absolutely reliable."

After that, he began to play the emotional card again, "My family died at the hands of orcs, I can't wait to kill all orcs, I won't joke about the mission." ”

Speaking of which, Xia Duo didn't ask anymore, but Ava's presence was always like a thorn, making it difficult for him to feel at ease.

The others are all knowledgeable, only Ava, who has not said a word throughout the whole process, and still plays and disappears from time to time, how can this be reassuring?

After thinking about it, Xia Duo decided to ask Master Horst, who had previously distributed badges, to reassure him that no matter what the outcome was.

After separating from Gibb, Shado left the camp under the pretext of going to Dean.

The place where Master Horst was located was not far from Chardo's current camp, and it was only necessary to bypass the two training grounds to reach it.

And just as he turned a final bend and was about to meet Master Horst, Xia Duo suddenly felt a cool breeze blow through the back of his head, and then a gloomy voice sounded from behind him—
