Chapter 2021: Low and high

"Om--"
The strange and weird low-pitched sound murmured quietly from the bottom of the sea, making it almost breathless. But if you don't listen and focus on it carefully, if you just walk away for a while, it will disappear in a blink of an eye, and you can't help but wonder if you have a hallucination.
"It seems ... a little bit like bubbles?"
Professor McGonagall said this, and then subconsciously looked up in the direction of the other two people around him. But it was such a momentary effort, but she suddenly stunned-because the voice suddenly disappeared?
After a short pause, I saw her hurriedly closing her eyes again, listening carefully and discerning for a moment, and then recaptured it as if it was extremely subtle after a few minutes ... but after hearing it, she could immediately feel Its presence is inexplicably weird and buzzing.
This strange and contradictory extreme contrast immediately made McGonagall more disturbed.
In fact, Snape, who is better at this aspect, obviously feels more deeply than her. He naturally heard this voice, and not only that, he also gradually heard something different from it.
"Professor McGonagall, just leave it to me and Professor Sprout here. Go ... use emergency means to contact McLean!"
At the time, the plan for studying abroad was originally proposed by Maca. During the entire organization and preparation process, he also led many matters. Therefore, he would leave one or two means of emergency contact here, and it became a matter of course.
"Maca ... well, good."
McGonagall was a little hesitant, then nodded, and then returned to the cabin just like Flivi had just been. And after closing the door, she had not forgotten to replenish the protection spell that Snape used to block the mist.
But I asked her why she was hesitant at first ... In fact, except for the French side, which is the rear of the current battle front, the direct connection between Maca and Change was actually completely Interrupted for many days. She is now asked to try to re-establish contact with Maca. To be honest, even if emergency means are used, she is not sure if she will succeed.
Needless to say, what is worrying about Maca's problem is not just the people who are against the Alliance!
After a while, McGonagall went straight through the middle aisle, rushed into the room at the end, and closed the door with a backhand sound.
In this way, nearly ten minutes later, the door of McGondon's room remained motionless, but new conditions appeared on Snape and Sprout on the deck.
"strange?"
Suddenly, Sprout, who was watching Snape's attention with the situation in the sea, became more and more confused, and she heard her whisper to herself:
"There's a constant noise coming from below, but my hurricane algae is not moving at all ... Severus, you just said you saw a huge creature, is it true?"
"I'm not sure it's a" bio "!" Snape heard, immediately shook his head, and listened intently while listening to the voice, "but the voice should sound deeper on the ocean floor. ... how much of your seaweed has multiplied? Where have you been? "
"I can't give specific numbers," Sprout said. "But at the beginning, I used them with powerful biocides, potions, and you should know better than me what they can achieve- The main material of the biocide is dragon blood diluted a hundred times! "
"Dragon Blood? So to say--"
Snape heard her say that she could not help but start to mentally calculate the effects of medicinal power and the diminishing effect of seawater dilution. However, the consequence of such a distraction is naturally to "lost" that buzz.
For a moment, he hurriedly set aside the calculations that were not necessary in his mind, and searched again for the sound that originated underwater.
After listening to his ears for a few minutes, he recaptured the once lost voice. But this time, when he heard the sound again, he immediately frowned.
"Wait!" Snape hurriedly whispered, "Sprout, don't listen! That voice ... um ..."
...
The sound suddenly rose!
Obviously, those who perceive this buzzing sound and listen to it naturally are not few in the change number-including a group of little wizards who study in the teaching cabin.
After a previous accidental tilt of the ship, Alexander, who had fallen, has now returned to his seat. At the same time, many of the classmates who were not quite at peace before were mostly quiet.
Yes, the forward tilt of the Change is undoubtedly extremely rare. This is the first time that such a large tilt has occurred since everyone boarded the boat. Today, it ’s important to know that even when sailing through the Antarctic circulation, The change number just shook for a while.
Because of this, when the abnormal change just appeared, the little wizards couldn't help secretly saying badly. Then, together with the previous situation that Professor McGonagall was called out by Snape, everyone couldn't help but shut their mouths and their hearts were stunned.
In this situation where nothing is clear, to sit honestly and wait in situ, this is what these students should do-their students in recent years can be considered to have experienced several disasters one after another in recent years. It's a trivial matter. In case of an accident, I know how to do it.
Not to mention ~ EbookFREE.me ~ Professors often apply for five orders after class, and it is difficult to not listen.
Although ... children! There are always a few little guys who still can't settle down ... for example, those little lions that slipped out early.
"Ok?"
For about half an hour from start to finish, although Ens, who was sitting in the back row, didn't seem to care much about it, he was silently watching in his heart. Especially the strange noise, he heard it, and he was always watching.
As for the magic book on the desk ... In fact, he hadn't read it.
And it was also at this moment, when the inexplicable sound suddenly rose, the tone changed from a low moment to a high voice, and finally turned into a disturbing beep, he and others were listening. People just felt a "buzz" in their heads, which made him frown, and subconsciously raised his hands to cover his ears.
But at this moment, everyone suddenly realized that covering their ears or something didn't work!
