Just as Fort Blois received the news that the fog had moved rapidly to the Strait of Dover, a dazzling "flame mushroom" bloomed in the fog area above the sea.

"Boom-"

Harry and Sirius, who were in the warehouse preparing to lead the patrol team back, felt the ground tremble beneath their feet, followed by a loud bang coming from the direction of the Strait to the west.

When the two of them hurriedly ran out of the warehouse with their teammates, stepped on the broomsticks and wanted to go to the beach to see what was going on, a huge tsunami slammed towards the port like a high wall.

"Climb! Fast! ”

Thankfully, the patrol members who were selected to stay at the outpost were good at flying, and everyone was calm enough. Otherwise...... It must be said, don't underestimate the horror of water because of the harmless appearance of humans and animals on weekdays, if you are swallowed by the amazing tsunami, that is, there are flying broomsticks, and they don't want to come out alive!

"What the hell is this...... What's going on? ”

Flying high into the air to avoid the tsunami, Harry and the others had the time to take a closer look in the direction of the channel. However, the dense gray fog did not dissipate after these explosions, making it impossible to see what was happening.

"That was an explosion, right?" Harry looked shocked and said to Sirius, "Could it be Helbo?" No...... But why do you want to do this on the surface of the sea where there is nothing? ”

But this time, even Sirius, who was well-informed and quick-witted, didn't know how to answer his question. After hesitating for a moment, he could only frown and say slowly:

"I don't know, it's just ...... I don't think the explosion was Helbo's doing—of course, it's certainly true that it had something to do with him. If you have to say it...... I think it's more likely that someone is attacking him to try to stop the fog from landing on the French side. ”

This speculation, when Sirius said it, could only be regarded as a guess. But soon, his last sentence seemed to have been proven - well, not to mention who caused the explosion, at least the fog that had moved into the strait really suddenly stopped.

"Sirius," Harry asked again hesitantly, looking at the stagnant fog, "...... Shouldn't you check it out? Well, I mean, even if it's just a walk around the fog zone. ”

However, Sirius shook his head when he heard this.

"No!" He said quite seriously, "Since ancient times, many cases have taught us that when we don't even know what's going on, it's the right choice not to approach!" After all, at such a time, wouldn't it be enough to tell Maca everything we have seen? With his wisdom, he will definitely give us a sufficiently accurate answer. ”

"Ahh Well, yes! Harry nodded hurriedly and said, "That's it." ”

However, just as Harry was about to convey the matter to Maca in Blois Castle, Ginny's letter through the magic of the Blois family was delivered to him first.

"Sirius," Harry whispered, staring at the letter, "Marka said we could go back." ”

……

News of the explosion in the middle of the Strait of Dover came a little faster than Harry.

To be honest, when Maca heard the news from the old butler's mouth, he couldn't help but wonder for a while, and then after some thought, he figured out a possibility.

In fact, according to the family wizard who reported to Fort Blois, the explosion that had occurred in the fog and no one could see the true face was even more powerful than the explosion of a horde of living corpses that had almost blown Maca to death.

And who else could have caused such a horrific explosion...... At least as far as Maca's judgment is concerned, that's beyond even Helpo's grasp.

"It's a Muggle," Maca, who had finally returned to bed honestly, couldn't help but say with great seriousness after a deep thought, "it should be right...... It was a terrible weapon that Muggles had developed, or rather, a kind of 'Muggle magic'! As for which side is the one who did it...... Mr. Butler, I have to trouble Mr. Blois to go to Madame Maxim, and then ask her to ask the Muggle head of France! ”

"Okay, Mr. McLean, I'll go."

Seeing the old butler leave again, Willie couldn't help but ask suspiciously:

"Maca, what do you mean by 'Muggle magic'?"

It would be difficult to explain to a wizard who didn't know much about Muggles. So he didn't intend to say it carefully, so he said directly:

"In short, it's a disposable weapon that can cause a powerful explosion. And after the explosion is over, it will leave a lot of ...... How so? A very intense 'toxin'? ”

Of course, the specific situation needs to be really investigated to be judged, not to mention that Maca herself may not know much, so I can only explain it so simply.

Seeing Maca following her, she turned to say:

"All in all, the explosion was in the fog, and it was still on the surface of the sea - it didn't matter to us that much. I'm just worried about Harry and Sirius. ”

But before the words fell, the old housekeeper who had only left for a short time came back again, and with him came back, there was a good news that was enough to relieve everyone's worries.

"Mr. McLean, Mr. Potter and Mr. Black, and the team that remained in Calais at the time, are already in the hall. It's just that the head of the house doesn't have time to meet them yet, so I'll let you know directly. Look, don't you let a few people come over? ”

"Marca, I'll just go," Ginny said as soon as the old butler finished speaking, "I'll bring Harry and Sirius over directly—"

"No, no," Marka said immediately, "Luna, Delphi...... Help me, and we'll go together!" ”

"Maca, how can this work! You'd better lie down! Hermione, who was on the side, hurriedly said, "You need to rest." ”

"yes!" Maca smiled, "Need to rest...... But certainly not now—as you heard just now, Mr. Butler, the fog has stopped moving. And this ...... I think in other words, the waves were really in there when the explosion happened! ”

"And now...... He was probably gone. ”
