After all, London has become an empty city, an "empty city" in the true sense of the word.

A city without people may no longer be called a city. Every street was empty, there were no living people, not even dead people, only the ruins of the war seemed to be silently pouring out the prosperity of the past and the sorrow of the present.

The grey fog that had enveloped the city of London for days gradually drifted away.

Yes, the fog drifted away—along with a group of special living corpses that were not so different from the vanguard outside.

It turns out that Kingsley's concern was at least half of his guess right, that there was "something" in the fog that suddenly began to move. However, it was not Helbo himself who made most people's hearts worry, but a group of more powerful living corpses that were small in number, but their strength should not be underestimated.

However, it is worth mentioning that Harry rushed to the end of the army of living corpses in one go, and witnessed the scene of the fog gradually enveloping the group of living corpses.

There was even a discovery that was very important for the clean-up team...... Or a very "bad" accident.

However, he was unable to witness the special living corpses that were in the center of the fog at that time......

……

"Kingsley."

By the time Sirius had carried Harry to the rear of the battlefield at a rapid pace, the fog had not yet approached the point where it was necessary to dodge, that is, the clearing teams on the front lines had not yet begun to retreat.

"Little Sirius...... Porter? ”

Kingsley glanced at Sirius at first, but soon caught a glimpse of Harry, who was being carried behind Sirius' back. When he saw Harry's appearance as if he had just been fished out of a pool of blood, he immediately showed a worried expression.

"Hurt? What's the delay...... Sirius, send him to the back for treatment! ”

"No, I'm fine, Kingsley!"

Before Sirius could reply, Harry struggled to slip off his back, then grabbed Sirius by the shoulders and said to Kingsley:

"It's basically the blood of those living corpses...... Well, let's not mention this yet! Kingsley, there's not so good news I have to report to you first! ”

After saying this in one breath, Harry took a slight breath before he said with a serious expression:

"In fact, just now I had been rushing from the front line of the battle to the end of the army of living corpses. I noticed that the fog drifting from London seemed to move much faster than I had imagined...... Did the Aurors who rushed to investigate send back a notice about this matter? ”

"Huh? So fast? ”

When Kingsley heard this, he raised his head in surprise and looked again in the direction of the fog.

"No, there was no news from either exploration team, and no one ever returned-"

"Compared to them, I walked in a straight line, but it took a lot of time on the way. It stands to reason that they should be quicker than me......"

Harry couldn't help but frown, as if he was a little worried about the Aurors who were willing to sacrifice themselves, but he immediately shook his head again.

"Well, it may not necessarily be an accident......" he said, "Kingsley, there is another more important thing—"

"What's the matter?" Kingsley immediately asked.

"It has something to do with the living corpses that have been knocked down by our spell and are incapacitated," Harry replied, "...... Well, how to say it? 'Corpses'? In short, they got up from the ground again after coming into contact with the fog that filled the past! ”

"What?"

This time, Sirius was surprised to change. As someone who really knocked down a lot of living corpses at the front line, he will naturally have a deeper feeling for this situation of the enemy being "resurrected" again.

To be honest, just turning the dead into a living corpse is enough to make people feel frightened, but how do you know that after those living corpses have fallen, they can actually get up again?

"Harry, exactly? How did those corpses 'get up from the ground' this time? Sirius hurriedly asked, "Under this purge attack, there are quite a few living corpses that are not even physically complete!" ”

That's right, it's not just the razor-sharp Gryffindor Sword that can tear those living corpses apart. Just like the powerful Split Spell and the Thunderbolt Explosion Spell, etc., if the strength reaches a certain level, even the corners of the clothes may not be able to remain.

"How do you get up?"

Under Sirius's questioning, Harry seemed to remember some of the unpleasant images he had seen at the time, and then wrinkled his nose and said:

"How so? It's like a children's building block...... Piece it together? Well, to be precise, it's a combination of unsuitable bricks...... That feeling. ”

"Shhhh It sounds like the radical alchemists of the past, trying to touch the forbidden zone of life...... It's unpleasant! ”

Just as Harry and Sirius both looked disgusted, Kingsley waved his hand and said:

"In any case, the next step is to reduce casualties as much as possible on our side. After all, it is undoubtedly very difficult to collect the corpses on the battlefield, but if left unchecked, those fogs will create more enemies once they pass. ”

"As for how to solve the problem of re-recovery...... By the way, Sirius, didn't you mention the living alchemy that appeared in the Middle Ages? Please go back to Spiral Town immediately and ask someone who is good at alchemy! ”

"Well, too!"

Sirius said, trying to help Harry to find a healer in the back before making a run to Spiral. But Harry stopped his hand reaching out to him, shook his head slightly, and said:

"I can go myself, Sirius, go back! If this problem is not solved in time, the army of living corpses will only grow more and more, and it will become more and more difficult to stop...... When the number grows to a certain point, it's too late! ”

"You...... No problem? ”

Sirius looked at Harry, then nodded towards the still approaching fog and the front-line clearing teams that had begun to alternately retreat.

"Kingsley, then I'll go back first."

Before the words fell, with a momentary distortion of space, Sirius apparition shifted away.

"Potter, can you really walk alone?"

"It's alright, Kingsley!" Harry said, "I'm just a little tired, I'll be back on the front line after a little rest." ”

In fact, Harry wasn't lying—he did suffer a few injuries, but only to the extent of a large bite on his arm.

Rather than saying anything, the fact that he met Aunt Petunia in the group of living corpses before was the biggest reason why he was so tired.

"Whew-"

Looking back at the hordes of living corpses in the distance, Harry shuffled his heavy steps towards the healing area at the rear.
