Christmas is coming.

The Christmas Eve of the second year of the Blue Sword is expected to be spent in the city of Palermo.

However, there was a certain eerie atmosphere in the team.

To be exact, this strange atmosphere has been present since the last time I returned from a team-building holiday in a seaside town.

Everyone no longer sits together talking and laughing, and more time is spent in groups of three or five whispering, not knowing what they are discussing.

What makes Aske even more puzzling is that the so-called "three-to-five group" is actually not fixed.

Sheila, for example, sometimes chats with Peggy alone, sometimes talks to Nora with a smile on her face, and sometimes whispers a few words to Miel mysteriously.

Sometimes they get together with Medea, as if they are talking about something intimate, and from time to time they look at each other and smile with a sharp heart, as if the two have already been embarrassed.

Then again, if you've befriended everyone, why do you have to talk to each other privately?

Although Aske was a little uneasy about their small actions in private, he didn't force them to understand. After all, no matter how complicated the circle of girlfriends between girls is, it is impossible for him to integrate into it as a big man.

Asker is not a figure like Jia Baoyu. As long as you don't have problems in business, let them go.

In addition to the trivial chores such as children's personal affairs, after defeating and subduing the Outville family, the overall combat strength of the team has also been greatly improved.

It is worth mentioning that after nearly half a month of running-in, Sidlifa finally let Navia Bone Tooth recognize the master.

Combined with Sidlifa's description, Asker was able to confirm that the Navia Bone Fang was an "epic artifact" (i.e., an artifact with powerful abilities in its own right, but with harsh requirements for the user), and that its use came at the cost of drinking blood.

It needs to eat a certain amount of "killing intent" every day before the user is allowed to continue using it. This killing intent can be automatically drawn from the process of killing enemies, or it can be voluntarily offered by the user (i.e. replenished by suicide).

Of course, Navia's bone teeth themselves have the effect of storing killing intent, and can be stored in advance for the next year's use, so Sidlifa doesn't need to kill people every day to replenish its food.

After confessing the Lord, Navia Bone Fang will only obey Sidlipha's command in most cases. Unless Sidlifa instructed it to help others, or had been deprived of its food for a long time, causing it to rebel.

It's just that the new owner directly authorized the two little girls to use it on the day after it recognized its owner, which made Navia Bone Tooth a little confused.

"Summon another one!" Mia commanded Navia Bone Tooth Road.

The surface of the Navia bone tooth on Sidlifa's neck suddenly flowed with a mysterious light, and then the outline of a wolf appeared in front of the three of them.

Like a pencil sketch on a blank piece of paper, the general outline of the wolf emerges out of thin air, then the detailed outline, then the color of the fur, and finally the living Fenrir wolf appears in front of everyone.

Call of the North.

Navia's ability to summon a transcendent creature from the north that obeys the user's will by consuming stored killing intent.

This summoning is not the same as Mi'er's destiny ability. First of all, it is a one-time thing, i.e., it can be summoned by consuming killing intent, and there is no additional cost to maintain the existence of supernatural creatures.

As a result, the Outville family has long used it as a monster farming artifact, thus obtaining a large amount of spiritual materials for cultivating the Northern Horn army - which can only be described as an evil use when the artifact does not recognize its owner.

Secondly, summoning consumes mainly the killing intent stored in the artifact, as well as a small amount of spirituality used to induce; If you send the supernatural creature back with the summoning of the supernatural creature, you can also return some of the killing intent that was originally consumed.

In the case of extreme pressure, this characteristic that can save spiritual consumption is naturally extremely precious, which is equivalent to saying that the summoned extraordinary creatures are completely free of charge.

As for the summoning itself, it belongs to the kind of super reinforcing ability.

For example, the only people in the team could fly, Sheila, Eleanor, and Asker, but in the future, Sidlifa could summon a Siberian Thunderbird and carry her into aerial combat.

For example, when encountering Peggy's unreasonable nirvana skill such as "Curse to Death", you can also summon a transcendent creature to act as a meat shield to replace death.

The summoned creatures of the North are positively related to the user's own level and the consumption of killing intent. So all morning, Mia, Mi'er, and Sidlifa have been researching and exploring the summoning range of Navia's Bone Fangs, and have summoned nearly a hundred different northern transcendent creatures.

Fenrir's Wolf, Siberian Thunderbird, Dream Eater's Snake...... Countless transcendent creatures that had never been seen before continued to appear, making the three girls almost dazzled.

"Stop playing!" Seeing that Mia had dismissed the Wolf of Fenrir from the summon again, Mi'er hurriedly dissuaded her and said, "Don't forget what we're here for!" ”

The transcendent creatures summoned by Navia's Bone Tooth do not belong to this world, or even to this era, which means that this ability essentially contains certain laws of "space" and "time".

By studying its summoning ability and completing their own law perception, it is the most important thing for Mia and Mi'er to do at the moment.

"Okay, okay." Miya still listened to Mi'er's words, so she honestly summoned again, and at the same time began to spiritually observe the process carefully.

In Miya's perception, this summoning phenomenon is very strange.

If space is compared to a uniformly distributed sponge, then the summoning ability of Navia's bone teeth is that a large glass ball suddenly appears inside the sponge.

Due to the appearance of foreign matter out of thin air in the inner position, the evenly distributed sponge around it is squeezed outward, and the distribution becomes uneven.

This disparate anomaly appears only for a moment, and then quickly returns to a homogeneously distributed steady state.

Because the volume of space is so large, compared to Miya's observation range, it can almost be equivalent to an infinite sponge.

Suddenly stuffing a new object into it causes the surrounding space to distort, which in turn quickly conducts to the surroundings. Each distance traveled, the amplitude of its distortion decreases slightly, until it is completely smoothed out in the infinite distance dimension.

It's like a drop of water falling into the surface of a lake, causing ripples. In a short period of time, there will be some disturbance of the homeostasis of the entire lake surface, but this disturbance will soon spread and gradually dissipate, and finally calm again.

Well......

Miya suddenly came to her senses and took out Lancelot's dagger.

Her spiritual instincts revealed a subtle premonition that she had comprehended the second half of the Sword of Ripples, that is, to emerge from its designated location.

However, what is the principle behind the first half of the Sword of Ripples, that is, how it disappeared from its original position?

So she lifted the call again.

Under the spiritual perception, I saw a flash of light on the surface of Navia's bone teeth, and then a dot appeared inside the transcendent creature.

Exactly, it was a "collapse".

Miya suddenly remembered that when she was in class before, she had heard Sheila talk about the principle of "gravity".

The essence of gravity is the gravity well, that is, the distorted collapse of space.

It's like smashing a hole in a two-dimensional plane, then the two-dimensional object on the plane will "collapse" into the hole, and the collapse to the end is a one-dimensional line segment, which means that the two-dimensional object has been completely reduced.

However, as soon as it collapses, the two-dimensional object will detach from its original plane, which is known as vanishing - perhaps this is how the unsummoning makes the supernatural creature disappear.

Therefore, if we first "collapse" ourselves, disappear from somewhere in this world, and then "reverse collapse", can we appear from another place in this world?

However, how to precisely control the location of the disappearance and appearance, so as to realize the fixed-point teleportation of the Ripple Sword?

The more Miya thought about it, the more she frowned, and her expression gradually began to stagnate, falling into a state of being stuck in a bottleneck and not having an epiphany, as if she had gone mad.

Mi'er looked at her wordlessly, first gesturing for Sidlifa to keep quiet, and then pulling out Asker's voice at some point in the past.

That was when Mia and Mi'er had not yet entered the team after the Heavenly Mountain dungeon, and Asker once explained to everyone the principle of the half-plane of Heavenly Mountain:

“…… The Overworld space we live in is like a page in a book. ”

“…… We are two-dimensional little people on the page. ”

“…… If you bend the page......"

In an instant, Mia, who heard this, was like an initiation, and suddenly broke through the bottleneck of thinking:

It's not just a collapse.

There is also a directional twist.

It's like point A and point B on a book page, and you need to walk the length of line segment AB from A to B.

However, by folding the pages in half so that points A and B are close to each other, the length of the line segment AB can be shortened.

Then, I collapsed myself, causing me, a "two-dimensional little person", to briefly leave the page from point A, and then re-enter the page from point B.

This is the mystery of the "teleportation" of the Sword of Ripples.

As for the method of self-collapse, of course......

Miya looked at the Lancelot dagger in her hand and waved it without hesitation.

Then she disappeared where she was.
