Delphi is not sure what the "arrogance" behind the corpse wants to do with the black flame vortex. Perhaps it is to directly rely on this to attack the protective barrier of the stronghold, or what further changes are unknown.

But no matter what the other party wants to do, the soul flame that has turned into a vortex and expanded must be the foundation, which is certainly not wrong.

In that case... While the black flame vortex has not become more terrible, seizing the time to "put out the fire" has become the only thing that Delphi and his colleagues have to do.

"... fuel? Yes, fuel!"

Looking at the black flame whirlwind, the momentum is getting stronger and stronger. Within the range that can be shrouded, the living corpses are swallowed into it, and continue to increase their momentum with the self explosion.

Obviously, although the soul flame of the corpse is very different from Safina's, it is still a flame derived from the soul rules after all.

All flames, of course, need fuel to burn, and the so-called soul flame, at present, its fuel is the changed soul in these living corpses!

"Mr. brova, join me to separate the corpses from the flame of the soul."

Delphi only said that, then he put out his wand and pointed forward. For a moment, a large area of cold air suddenly flew out and went away in the direction of the black flame vortex.

This comes from the ultra-low temperature cold current with regular cooling rules. In fact, it can not affect the soul flame, but it can freeze nearby corpses in an instant. When the cold air collided with the black flame, it even passed through the black flame vortex without any loss, and continued to float to the East safely.

At present, the living corpses on the south tower are naturally crowded along the barrier from the East. With the cold of Delphi further spreading to the East, even more living corpses coming here are frozen on the way. In addition, the corpses that had been frozen into ice sculptures indirectly blocked the same kind in the rear. For a time, they finally cut off the largest "fuel" source that led to the rapid expansion of the black flame vortex.

Of course, at the same time, brova was not idle.

He was not a fool. When Delphi said the word "fuel", he actually knew what the other party was going to do.

So when Delphi waved the cold current to freeze the army of living corpses, blova also stretched out his wand. As soon as the cold current rolled past the black flame vortex, he immediately raised his wand.

"Boom -"

With a surge of ground, the frozen corpse ice sculpture near the black flame storm was suddenly pushed and buried by the surging soil waves, leaving a large blank area for it in the blink of an eye.

It must be said that it is also difficult for brova to do this - he can gather earth and stone into giants with the help of summoning, just like the flame flying dragon he summoned in the East. But he can directly control the churning of the earth like sea waves. As soon as the scope is large, his spiritual power is not enough.

Fortunately, Delphi had decided so decisively that by this time, the black flame vortex had not expanded beyond his power.

After a while, seeing that the black flame vortex without fuel began to collapse and shrink, it was no longer as fierce and turbulent as before, and Safina in the barrier could not help but breathe a sigh of relief.

After all, the black flame can eventually become a vortex and begin to accelerate its expansion, which has something to do with her rash action.

"Delphi, and Mr. brova... Thank you..."

Safina seemed to want to express her gratitude, but before she finished, she saw Delphi wave her hand and interrupt her words.

"Don't be busy yet, thanks," said Delphi, still frowning, pointing at the shrinking black flame vortex with his wand. "Maybe... It's not over yet."

Because "arrogance" has not appeared yet, she, who knows the power of those demons, can't relax for a moment. Just stared at the residual black flame again. When it finally dissipated completely because it was too hot to burn, it finally nodded to blova and Safina.

"For the devil, it shouldn't be difficult to make a big black flame like that at the beginning again. The first time, there will be a second and a third time... Miss Geoffrey, handle it carefully."

Facts have proved that Delphi's last worry seems superfluous. However, it is a good thing to successfully solve the problem given by the other party.

"I see," Safina nodded at her, "you two go back and have a rest! During this period, the defense of the stronghold will be left to me and Granger."

Then she turned and glanced at the front of the tower full of frost and earth hills. Then she got up from the platform and went to the East Tower again.

Obviously, there will be no problems here for the time being, and the East is the place with the greatest pressure in this defensive war.

……

As he looked at him and hurried away, Delphi motioned to blova again, intending to return to Harry again and have a rest.

They came in a hurry and had to fight immediately. They didn't have a long rest, but they became more tired.

But just then, Delphi, who had turned the ice bird under his feet, heard Mr. brova's voice behind him.

"You go first! I'll stay here for the time being and replace you later - Geoffrey alone runs around the barrier, which is easy to go wrong."

"Well," said Delphi, hesitating a little, and then nodding, "it's all right."

Although it is accurate to say that Safina is not the only one running back and forth in the stronghold at this time, just like Neville and a group of volunteers with good strength, they also help in the weak areas of the defense line.

However, they both know that only a few people really have the ability to do something in the event of an accident.

After a reply, Delphi drove the ice bird up again and flew straight to the broken house they had chosen before.

A moment later, Delphi stepped back into the living room and said to Harry, who was still sitting in front of the window where she had sat:

"Arrogance hasn't appeared yet. We have to wait... Besides, Mr. brova stayed near the south tower. We'll replace him later."

"I see," Harry nodded. "I saw it all."

"Well, then have a rest!" Delphi nodded slightly, and then walked straight towards the broken sofa. "In fact, I'm a little tired."
