Delphi knows very well that even though she has recovered her strength now, she is even a step further than before. But in the face of such a large number of corpses, it will still be unable to do what it wants.

In particular, the line of these corpses was still very long in front of her - she could cooperate with Mr. brova and Harry to destroy such a small group of enemies as before, but she obviously could not ensure that the whole army would be wiped out again and again before the corpses attacked the stronghold behind her.

Not to mention, behind these corpses, there is a demon "arrogance" who doesn't know where he is hiding!

Therefore, Delphi knew that the defensive war of the large-scale attack of the corpse on the stronghold would be officially launched sooner or later.

"Mr. Potter, please ask Hermione to remind miss hornheim..."

It was precisely because he knew that the stronghold would sooner or later be attacked by these living corpses, Delphi immediately realized that it was time for Harry and them to remind Sarah, who maintained the alchemy barrier, after seeing that the living corpses had burst out of the flame of soul.

No way, because the soul flame is extremely aimed at the characteristics of spiritual power, if they explode on the alchemy barrier as just now... I have to say, the consequences may be unpredictable.

At least as far as Delphi knows, alchemy itself is a magical discipline that focuses on controlling matter with spirit. That is to say, the alchemy barrier maintains spiritual contact with Sarah almost all the time.

Therefore, even if the soul flame can not be called the "alchemy Nemesis", at least in theory, Sarah will probably not be good at that time - if she wants to resist the repeated bombing of the soul flame of the corpse army, it means that she must have an invisible positive confrontation with "proud slow".

But... Can Sarah compete with the devil one-on-one? Seriously, Delphi doesn't think much of her.

……

"... powerful is powerful, but this time, she can't stop it. So many enemies can't be solved by two or three people - this is a real 'War'."

When Delphi passed through the black flame of the corpse and the barrier of the stronghold and was thinking that Sarah and the devil would have an indirect battle today, she didn't know. In fact, Sarah was thinking about her.

Just now, Sarah sensed Delphi's attack on the leading troops of the dead from a distance.

Naturally, she soon thought of the same point with Delphi.

"But," whispered Sarah, looking at the increasingly hot battlefield in the East, "is that the flame of the soul? It's... Some trouble."

In the face of other types of attacks, in addition to the unprecedented power of the giant demon "anger" not long ago, the rest of Sarah really didn't worry too much. Whether it's physical damage or magic, her alchemy barrier can block it.

But who knows, what he wants to resist now is the ghost thing of "soul flame".

Sarah was thinking. Suddenly she saw another figure. Suddenly she took off from the top platform of the East Tower, and then flew towards the burrow.

Immediately after Sarah, she found that it was not Hermione, but a volunteer wizard.

"Excuse me... What's the matter? What's the matter?"

Seeing that the other party flew in a hurry on a broom and soon stopped in midair not far in front of Sarah, saraton asked in some doubt.

"Well," the wizard hurriedly explained, "the young lady named Delphi asked us to remind you that... It is said that the living corpse will launch a large number of very special attacks on your alchemy barrier, miss hornheim - that is the 'flame of soul', which may hurt you if you resist it forcibly."

"Oh, I know that," Sarah nodded at each other. "Go and tell Miss Granger that I'll pay attention."

The wizard came to Sarah and simply conveyed Delphi's meaning to Sarah. Then he took Sarah's answer and soon returned to the East Tower.

And the fact is, as Delphi speculated, that the flame of the soul is a little tricky for Sarah. In particular, although the soul flame on the surface comes from the souls of one living corpse, in essence, it still comes from the demons.

So, after the wizard who came to preach went away, Sarah no longer stayed on the roof with nothing, but followed her back to the attic through the trap door.

A complete set of alchemy array used to create the protective barrier outside is built on the floor of this attic without any cover and concealment. After Sarah came down, she only checked the formation again, and then suddenly raised her legs and stepped into the formation.

Whether the coming attack is strong or weak, as long as Sarah wants to go all out to defend, the person who arranges the formation must be as close to the formation as possible. Even like her now, she can go directly to the core of the formation and sit down on the spot, waiting for the enemy's attack.

That is, after Sarah waited silently for a few minutes, as the army of living corpses from the East pushed forward again and again, Delphi and her three seemed unable to stop all the living corpses at last. They could only look at one side from a distance, and several living corpses rushed towards the alchemy barrier behind.

"Boom -"

An explosion came from far east.

Although the sound had eased a lot by the burrow and Sarah was in the attic again, she was quite clearly aware of the explosion itself - the attack through the alchemical barrier she supported.

It must be said that the power to attack the soul like this is really terrible. Sarah's soul still hasn't been completely completed, and she undoubtedly suffers some losses when she bears this attack on her soul.

But the good thing is that as one of the only two peak products of alchemy, Sarah's mental strength is actually very high.

Even if she suffered some losses, even if she was really facing a demon, it wouldn't be a problem for at least a while.

"Boom... Boom... Boom..."

Unconsciously, more and more corpses were leaked by Delphi. Every explosion means that Sarah has suffered another impact.

As time passed, her face turned a little pale.

"I don't know if there's anything wrong with Sarah."

In front of the lookout of the East Tower, Hermione kept instructing other wizards stationed here to attack more and more corpses outside, and looked back towards the Burrow with a little worry.
