"That's?"

Blois, who was trying to see if he could get the giant demon to sink deeper, suddenly glanced up slightly again—he actually wanted to see if Safina was preparing other attacks, but this look made him inadvertently see a touch of blue.

It was a giant ice bird, and in some details, it seemed to have characteristics that were almost identical to those of his flaming wyvern.

“…… Summoning? ”

Just as Blois was surprised by this discovery, Safina, who was unleashing black flames to try to continue suppressing the demon, suddenly heard a whistling sound from far and near behind her.

At the same time, a shout resounded through the airspace.

"Miss Gauferyn, get out of the way!"

This voice, is it the strange Muggle girl named Delphi?

Safina paused briefly, but the situation on the battlefield was always changing. She also knows very well that no matter how she chooses or does it at this time, "hesitation" will be the biggest taboo.

Therefore, Safina did not hesitate, and then rolled up the black flames all over her body, dodged to the side and flew away from her original position. And then...... In the next instant, a dazzling pillar of pure white light suddenly passed through the place where she had just been, and tilted downward towards the giant demon who was now half underground.

The demon was not slow to react, and instinctively dodged at the first time. It's just that the speed of the white light is too fast, and because it is sinking into the ground at the moment, its huge body has no way to dodge.

"Click-"

With a tooth-aching freezing sound, white ice crystals and frost suddenly spread across its black body, and where the white pillar of light passed through mid-air, there were also snowflakes floating in the cold.

"It's a cooling rule...... McLean's? ”

Blois looked at the icebird that had flown out of the alchemy barrier and hovered in the air...... To be precise, it was Delphi standing on the back of the ice bird, but her brow furrowed more and more.

At this time, Delphi can be seen raising her long-roded staff, and a regular rune appears on the top of the staff. It's just that compared to the one not long ago, this rune is now extremely clear, and the pillar of light released by it is much more dazzling than the last time.

Yes, the blinding white light had gradually brightened to the point where it was almost impossible to look at directly.

And this difference between the former and the latter is because when Delphi used this staff before, he was just a Muggle with no active magic, and he was able to exert the power of the rules only by the rune array engraved in the staff by Maca in advance, and the limited use of the natural magic of the outside world was not possible, which of course could not make the rule runes exert enough power.

But now, Delphi's magic has awakened!

At the moment, Delphi is using her own magic power to directly drive the rune of the cooling rule imprinted in the staff by Maca, which is equivalent to Maca, who has already reached the pinnacle of the study of cooling rules, and is borrowing Delphi's magic power to exert the power of cooling rules.

In this way, it is no wonder that Blois has the illusion that he has seen Maca herself—a power that no one can grasp.

"Click! Bang! ”

Suddenly, the sound of the giant demon struggling below rang out, dragging Blois and Safina, who were equally amazed at the scene, back to reality. The two of them hurriedly looked down again, only to see that the pillar of light was still attacking this guy, and the white frost had covered a large area.

In just a few seconds, not only the demon's massive body, but also the surrounding ground that had been turned into a huge trap by Blois was rapidly frozen, making the vast area below seem to be a field of ice and snow.

It must be said that, as a first-level rule, the pillar of cooling rule light released by Delphi may have reached the limit of what a wizard can master. Although its nature and effectiveness are not the same, in terms of the strength of the attack on the physical level, it has even faintly surpassed the soul flame that Safina used with all her strength just now.

Even if Safina still knows very little about the rules of the soul, you must know that even if it is only the skin, it is still a second-level rule!

But unfortunately, the first-level rule is the first-level rule, and there is always a limit. The power of the cooling rules is obviously not enough to completely freeze the giant demon.

"Click-"

The huge body covered in frost slowly writhed under its tremendous force, and the thick ice shell on the surface cracked again and again, and was refrozen by the pillar of light again and again.

Although in this situation, the giant demon could only move slowly, and could no longer climb out of the ground. But Delphi's magic is of course limited, and it is impossible to accompany it like this forever.

By this time, Safina and Blois had already realized that they should also help. But how can they help Delphi?

Just when the two hesitated, they didn't expect Delphi to make a new move.

"Go!"

I only heard her spit softly, and the next moment, the two of them saw her jump to her feet. At the same time, the huge ice bird that was originally under her feet suddenly accelerated, and with the bitter cold wind, it suddenly folded its wings and dived down.

"Get out of the way!"

Perhaps just remembering that there were two more people around there, Delphi reminded him. But in fact, it doesn't need to be said that Safina and Blois are also wizards who can sense magic fluctuations to varying degrees, and they have long sensed the surging power in the ice bird's body at this time.

And just two seconds after the two of them retreated and quickly moved away from the demon's location, the huge ice bird crashed headfirst into the demon covered in frost.

That's right, it was almost the same as the meteor of the Blois Flame Wyvern not long ago, slamming into it and exploding with a bang.

In an instant, a large area of ice mist dispersed in all directions, and the extreme low temperature enveloped half of the giant demon's body above the ground. Although that doesn't reach the limit of the Cooling Rule Pillar, it is evident that the area of influence is many times larger.

Because the mental power was a little unsustainable, the cooling rune on the front of Delphi's staff dimmed, and the pillar of light gradually dissipated. But in the ice mist below, the demon's struggle finally stopped.

"It works."

Safina was also staring at the white ice mist, and seeing this situation, she subconsciously spoke.

But on the other side, Delphi couldn't help but shake his head.

"It's just temporary, and you can't control it with the first-level rules alone."

At this time, Blois also descended from the sky and flew not far away beside her. It was clear that he seemed to care about Delphi's power, but it was clearly not the time to say that.

"And what are you going to do?" He asked.
