Chapter 2021 Deep and High

"Om—"

A strange and eerie low hum sounded faintly from the bottom of the sea, so low that it was almost breathless. But if you don't listen carefully and search for it carefully, it will disappear in the blink of an eye as soon as you distract yourself, making you wonder if you have auditory hallucinations.

"It seems...a little bit like a bubble?"

After Professor McGonagall said this, he subconsciously raised his head and glanced in the direction of the other two people around him. But in such an instant, she was taken aback for a moment - because the voice suddenly disappeared again?

After a short pause, she quickly closed her eyes again, listened carefully for a moment, and only after a few minutes did she recapture the subtleness... But after hearing it, she could feel it immediately. Its sense of presence is inexplicably powerful and weird humming sound.

This strange and contradictory extreme contrast immediately made Mag feel even more uneasy.

In fact, Snape, who was better at this aspect, obviously felt more deeply than her. He naturally heard this voice, not only that, but he also gradually heard something different from it.

"Professor McGonagall, just leave it to me and Professor Sprout, go... use emergency means to contact McLean!"

It was Maca who proposed the study tour plan at the beginning, and he was also the one who led and handled many matters during the whole process of organization and preparation. Therefore, it became a matter of course that he would leave one or two emergency contact methods here.

"Maca...well, good."

Mag hesitated for a moment, then nodded, and then went back to the cabin like Flitwick just now. And after closing the door, she didn't forget to refill Snape's protective spell that blocked the fog.

But I have to ask her why she "hesitantly" at the beginning... In fact, except for the French side, which is the rear of the current battle front, which still maintains contact, Maca's direct contact with the Change is actually completely complete. It has been interrupted for many days. Now she was asked to try to reestablish contact with Maca. To be honest, she was not sure if she would be able to succeed even if she used the backup emergency method.

Needless to say, those who are currently confused and worried about Maca's problem are not just people from the Rebellion Alliance!

Not long after, Mag went straight through the aisle in the middle, quickly rushed into the room at the end, and then closed the door with a "bang" with his backhand.

in this way,

Nearly ten minutes later, there was still no movement at the door of the room where Mag was, but there seemed to be a new situation on the side of Snape and Sprout on the deck.

"strangeness?"

Suddenly, Sprout, who was watching the situation in the sea together with Snape, became more and more puzzled, and she suddenly said to herself:

"Obviously there are noises coming from below, but my hurricane has not moved at all... Severus, you just said that you saw a huge creature, is that true?"

"I didn't say for sure that it was a 'creature'!" Snape immediately shook his head when he heard the words, and said casually while listening to the voice intently, "However, the voice should sound like it was somewhere deep under the sea ...how much of your algae has multiplied? Where did it go?"

"I can't give you the exact numbers," said Sprout, "but I gave them a strong booster in the first place, Potions stuff, you know better than I do what it can do— The main material of the accelerant is dragon blood diluted a hundred times!"

"Dragon blood? In that case—"

Hearing what she said, Snape couldn't help but subconsciously began to calculate the potency of the medicine and the diminishing effect of seawater dilution. However, the consequence of such a distraction, of course, is to easily "lose" that buzzing sound.

Startled for a moment, he hastily put aside the unnecessary calculations in his mind, and searched for the underwater sound again.

After some listening, it took a few minutes before he regained the once-lost voice. But this time, when he heard the sound again, he immediately frowned.

"Wait!" After a short pause, Snape hastily shouted, "Sprout, stop listening! That voice... um..."

...

That voice suddenly rose!

Obviously, there were not a few people on the Revolution who noticed the buzzing sound and naturally listened to it—including a group of young wizards who were studying by themselves in the teaching cabin.

After an accidental tipping of the previous ship, Alexander, who fell down, has now returned to his seat. At the same time, many students who were a little restless before also calmed down.

Yes, the forward tilt of the Revolution is undoubtedly extremely rare. Since everyone boarded the ship until today, this is the first time that such a large tilt has occurred-you know, even when sailing through the Antarctic Gyre before , the Change number just shook slightly for a while.

Because of this, when the abnormal change occurred just now, the little wizards couldn't help secretly thinking that it was bad. Then, in addition to the fact that Professor McGonagall was called out by Snape earlier, everyone couldn't help but shut their mouths, feeling uneasy.

In such a situation where they don't know anything, just sit and wait honestly. This is what students like them should do—these students have experienced several catastrophes one after another in recent years. Small difficulties, encounter accidents, more or less know what to do.

Not to mention, the professors often make repeated orders after class, and it is difficult not to listen.

Although... children! There are always a few little guys who are still restless...for example, those little lions who slipped out early just now.

"Ok?"

During the half an hour from the beginning to the end, although Ensi, who was sitting in the back row, didn't seem to care much about this matter on the surface, he was silently paying attention to it in his heart. Especially the strange sound, he also heard it, and he was still paying attention to it all the time.

As for the magic book on the desk... In fact, he hadn't read it for a long time.

And it was at this moment, when the mysterious and inexplicable sound suddenly rose, the tone changed from low to high in an instant, and finally turned directly into a disturbing buzzing sound, he and the others who were listening Like a person, he only felt a "buzz" in his head, which made him frown, and subconsciously raised his hands to cover his ears.

But at this moment, everyone realized to their astonishment that covering their ears didn't work at all!
