Chapter 2100 The Long-Lost Frost

"That is?"

Bulova, who was trying to see if he could sink the giant demon deeper, suddenly raised his head and glanced - he actually wanted to pay attention to whether Safina was preparing other means of attack, but he didn't expect this When he took a look, he inadvertently saw a touch of blue.

It was a giant ice bird, and in some details, it seemed to have almost the same characteristics as his flame flying dragon.

"... Summoning?"

And just when Bulova was surprised by this discovery, Safina, who was swaying black flames and trying to continue to suppress the demon, suddenly heard a whistling sound from far to near behind her.

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

"Miss Grofeyn, get out of the way!"

This voice, is that strange Muggle girl named Delphi?

Safina paused briefly, but the situation on the battlefield is always changing rapidly. She is also very clear that no matter how she chooses and what to do at this time, "hesitation" will be the biggest taboo.

So, without hesitation, Safina rolled up the black flames all over her body, and flew away from her original position in a sideways move. Then... At the next moment, a dazzling pure white beam of light suddenly passed through the place where she was just now, and slanted downward towards the half-body giant demon who was now underground.

The demon's reaction was actually not slow, and he instinctively made a dodge immediately. It was just because the speed of the white light was too fast, and it was sinking into the ground at the moment, there was no way to avoid it with its huge body.

"Crackling——"

Accompanied by a toothache freezing sound, white ice crystals and frost immediately spread on its black body, and the place where the white beam of light passed in mid-air was also filled with cold air. snowflake.

"Is it the cooldown rule...McLean's?"

Blois looked at the ice bird that had already flown out of the alchemy barrier and was hovering in the air... To be precise, it was Delphi standing on the back of the ice bird, but his brows frowned more and more tightly.

It can be seen that Delphi is raising her long staff at this time, and a rule rune emerges from the top of the staff. It's just that compared with the time not long ago, this rune is now extremely clear, and the beam of light released by it is much more dazzling than last time.

Yes,

The glaring white light has gradually brightened to the point where it is almost hard to see directly.

And the difference between the front and the back is because Delphi was just a Muggle with no active magic power when using this staff before, and the ability to exert the power of rules depends on the rune pattern carved in the staff by Maca in advance. Of course, the limited use of natural magic power from the outside world cannot make the rule runes exert enough power.

But now, Delphi's magic power has awakened!

Right now, Delphi uses its own magic power to directly drive the cooling rule runes branded in the staff by Maca. The magic power casts the power of cooling rules.

In this way, it is no wonder that Bulova has the illusion that he has seen Maca himself - such power cannot be mastered by everyone.

"Crack! Bang!"

Suddenly, the struggling sound of the giant demon below sounded again, dragging Bulova and Safina, who was also surprised by this scene, back to reality. The two hurriedly looked down again, only to see that the beam of light was still attacking this guy continuously, and the white frost had covered a large area.

In just a few seconds, not only the huge body of the demon, but also the ground around which Bulova had turned into a huge trap was rapidly freezing, making the large area below seem to have become a domain of ice and snow.

It must be said that, as a first-level rule, the beam of cooling rule light released by Delphi may have reached the limit that a wizard can control. Although the properties and effects are not the same, but in terms of the physical attack strength alone, it has even faintly surpassed the soul flame that Safina exerted with all her strength just now.

Even if Safina still doesn't know much about the rules of the soul, you have to know that even if it's just superficial, it's still a second-level rule!

But it is a pity that a first-level rule is a first-level rule, and it always has its limit. The power of the cooling rules obviously couldn't completely freeze the giant demon.

"Crack——"

The huge body covered in frost slowly twisted under its enormous force, the thick ice shell on the surface cracked again and again, and was re-frozen by the beam 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 magical power is of course limited, and it is impossible to accompany it like this forever.

At this time, Safina and Bulova actually realized that they should also help. However, how should they help Delphi?

Just when the two were hesitating, they didn't expect Delphi to make another move.

"go!"

She only heard a soft vomit, and the next moment, the two of them saw her suddenly jump up. At the same time, the huge ice bird that was originally under her feet suddenly accelerated, and with the biting cold wind, it suddenly folded its wings and swooped down.

"Stay back!"

Perhaps just remembering that there were two other people nearby, Delphi reminded her. But in fact, she doesn't need to say, Safina and Bulova are also wizards who can perceive the fluctuation of magic power to varying degrees, and they have already noticed the turbulent power in the ice bird's body at this time.

And just two seconds after the two of them stepped back and quickly moved away from where the demon was, the huge ice bird bumped headfirst into the frost-covered demon.

That's right, it was almost the same as the falling meteor of Bulova's Flame Wyvern not long ago, hitting it hard and bursting apart.

In an instant, with a large piece of ice fog spreading in all directions, the extreme low temperature enveloped the half of the giant demon's body exposed above the ground. Although that still couldn't reach the limit power of the cooling regular beam of light, it was obviously many times larger in the range of influence.

Because the mental power was slightly unsustainable, the cooling rune at the front of Delphi's staff dimmed, and the beam of light gradually dissipated. But in the icy mist below, the movement of the demon struggling finally stopped.

"effective."

Safina was also staring at the white ice fog, seeing the situation, she subconsciously said something.

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

"It's only temporary. It can't be controlled by the first-level rules alone."

At this time, Bulova also descended from a high altitude and flew not far from her. It can be seen that he seems to be very concerned about Delphi's power, but it is obviously not the time to talk about it now.

"Then what are you going to do?" He also asked.
