"What is that?"

Brova, who was trying to see if he could make the giant devil sink deeper, suddenly glanced up a little again - his original intention was to pay attention to whether Safina was preparing other attack means, but he didn't expect this look, but he inadvertently saw a touch of blue.

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

"... summoning?"

While buluowa was surprised by this discovery, Safina, who was throwing a black flame and trying to continue to suppress the devil, suddenly heard a whistling sound from far to near behind her.

At the same time, a loud cry also rang through the airspace.

"Miss Geoffrey, get out of the way!"

Is this the strange Muggle girl named Delphi?

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

So Safina didn't hesitate. She rolled up her black flame, flashed to one side and flew away from her original position. Then... In the next moment, a dazzling pure white light suddenly passed through the place where she had just been, tilted down and went straight to the giant devil half of her body now underground.

The devil's reaction was not slow. He instinctively dodged at the first time. Just because the speed of the white light is too fast, and it is sinking into the ground at the moment, its huge body can't escape at all.

"Kerala -"

Accompanied by a bitter freezing sound, the white ice crystals and frost immediately spread on its black body, and the place where the white light column passed in the air also overflowed with cold and snowflakes.

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

Brova looked at the ice bird that had flown out of the alchemy barrier and hovered in the air... To be exact, it was Delphi standing on the back of the ice bird, but his eyebrows were frowning more and more tightly.

It can be seen that Delphi was lifting her long staff, and a regular Rune appeared at the top of the staff. However, compared with the one not long ago, the rune now appears very clear, and the light column released by it is much more dazzling than the last time.

Yes, the dazzling white light has gradually become so bright that it is almost difficult for people to look directly at it.

This difference between the former and the latter is because Delphi was just a Muggle with no active magic when he used this staff. He was able to exert the power of rules by relying on the rune matrix engraved in the staff by Maka in advance, which limited the use of external natural magic. Of course, there is no legal rule Rune to exert enough power.

But now, Delphi's magic has awakened!

At present, Delphi invokes his own magic to directly drive the cooling rule runes imprinted on the staff by Maka, which is equivalent to Maka, who has already reached the peak in the research of cooling rules, using Delphi's magic to exert the power of cooling rules.

In this way, it's no wonder brova had the illusion that he saw Maka himself - such power can't be mastered by anyone.

"Crack! Bang!"

Suddenly, the struggle of the giant devil below sounded again, dragging brova and Safina, who were also surprised by this scene, back to reality. They hurriedly looked down again, but they saw that the light column was still attacking this guy, and the white frost had covered a large area.

In just a few seconds, not only the huge body of the devil, but also the surrounding ground turned into a huge trap by blova is freezing rapidly, making the large area below seem to become a field of ice and snow.

It must be said that as a first-class rule, the cooling beam released by Delphi may have reached the limit that wizards can grasp. Although the nature and utility are not the same, the attack intensity at the physical level has even faintly exceeded the soul flame that Safina has just put into full play.

Even if Safina knows very little about the soul rules, you know, even if it's just fur, it's a secondary rule anyway!

Unfortunately, the first level rule is the first level rule, which always has its limits. The power of cooling the rules obviously can't completely freeze the giant demon.

"Ka -"

The huge body covered with frost slowly twisted under its great force, and the thick ice shell on the surface cracked again and again and was frozen again and again by the light column.

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

At this time, Safina and blova actually realized that they should also help. But how can they help Delphi?

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

"Go!"

She only heard a light vomit, and the next moment, they saw her jump up suddenly. At the same time, the huge ice bird that was originally under her feet suddenly accelerated, suddenly folded its wings and dived down with the cold wind.

"Back off!"

Perhaps just remembered that there were two people nearby, Delphi reminded. But in fact, it goes without saying that Safina and blova are wizards who can sense the fluctuation of magic to varying degrees. At this time, they have long been aware of the surging power in the ice bird.

Just two seconds after they retreated and quickly left the devil's place, the huge ice bird hit the devil covered with frost.

Yes, it's almost the same as the meteor of the flame flying dragon of Bulova not long ago. It hit it hard and exploded.

In an instant, with a large area of ice and fog scattered, the extreme low temperature shrouded half of the body of the giant devil exposed above the ground. Although it can not reach the limit power of cooling regular light column, it is obviously many times larger in the scope of influence.

Because the mental power was a little difficult to sustain, the cooling Rune at the front of Delphi's staff dimmed, and the light column gradually dissipated. But in the ice fog below, the devil's struggle finally stopped.

"It works."

Safina was also staring at the white ice fog. Seeing such a situation, she said subconsciously.

But on the other side, Delphi could not help shaking his head.

"It's only temporary. It can't be controlled only by first-class rules."

At this time, blova also fell from 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's obviously not the time to say this.

"What are you going to do?" he asked.
