"Did you all hear that?" asked Harry as he got up from the water.

"Well, I hear you..."Hermione also stood up from the water, and shook her wet hair, "The meaning of the song is easy to understand, to take back our precious items from the merfolk's guardianship in an hour..."

"Merfolk, underwater," Harry said slowly, "Could it be that there is a group of merfolk living in the lake besides the giant squid?"

"Even if there is no school, they will bring in a batch...", Ginny closed the golden egg and surfaced, "after all, they can't let everyone go outside the school to watch the game, that would be more troublesome." ”

Neville breathed a sigh of relief, "It's good that it's just a mermaid... This sounds a lot easier to deal with than the fire dragon. ”

"'Just'? There are so many species in the Black Lake," Roger smiled, "Otherwise, do you think that the giant squid can grow so big with the feeding of the students?"

The little fat man's face immediately became unnatural.

"Relax, it's not without good news," Harry said comfortingly, patting Neville on the shoulder, "at least we don't have to spend our days and nights searching for a spell that will keep you underwater for an hour and still live to tell your story." ”

The bubble spell that Lupin taught them last year was not something that a fourth-grader could learn.

"Looks like I need to find out what the amazing creatures live in the water, after all, the black lake is so big," Hermione said.

"I heard that the bottom of the black lake is connected to the ocean, and maybe there will be a Fiztero trilodon shark~" Luna said excitedly with her eyes widened.

Whenever this happens, Roger and the others are so amused that they don't ask the mad girl what the 'Fiztero Trilodon' is. Because they can be sure that this thing is as unwarranted as the scimitar-horned snoring beast, and even the word 'Fitzgerald' is likely to be coined by herself.

In the next few weeks, in addition to practicing all kinds of evil spells, Hermione found something to do, and she held a book every day to teach a few people all kinds of underwater biology knowledge, I have to say, it was annoying...

"I think there might be a fire crab in the black lake, a crab that looks like a sea turtle, and the shell is studded with jewels, so it's easy to identify... When they are attacked, their butts will erupt with flames. I don't think it will cause us any trouble if we don't provoke it..."

"Oh, and the horsehead mermaid... We should pay more attention to this monster with a horse's head and forebody, tail and back in the shape of a fish, because the mermaid will take the horse-headed fish-tailed monster away and then tame it... Extremely fast in the water...."

"There's also Loba, a simple animal, generally ten inches long, consisting of an elastic nozzle and a venom sac. When threatened, Loba worms shrink their sacs and blast away their attackers with venom. Merfolk often use Loba worms as weapons..."

"And the soft-clawed land shrimp... Oh wait... Well, it's a land animal..."

It can only be said that the consequence of Hermione's approach is that it has made the other people feel the same tension as they did when they faced the first project. Now, whenever Neville gets close to the classroom window, he can't help but look at the big lake outside the venue.

The surface of the lake was a large iron-gray and gloomy lake, and the dark and cold bottom of the water was as far away as the moon.

But as Harry had said, the most important thing they could do was how to breathe underwater. After solving this problem, all that remains is to deal with all kinds of magical animals, including mermaids, with their own attack skills...

After Lupin's training in Xiaozao and Roger last year, they are very confident that they are not weaker than those three real warriors in this regard.

Just like the last time he faced the dragon, time slipped away again, as if someone had cast a spell on the clocks to make them spin faster. February 24th is a week away... Five days to go... Three days to go... One more day...

"Dripping into ice!" Neville cast a spell, but Hermione flicked it away with her wand, and the spell knocked down the sand at the bottom of the sea, instantly freezing a large area.

"Okay, you've pretty much got the spell in your hands, so let's stop here for today," Roger said to his friend after running to the shore underwater.

These days, their spell practice is done on the indoor beach with a requirement room, so as not to cause inconvenience or mistakes when casting spells underwater during matches.

"Poof..."Hermione and the others stepped on the water and surfaced one after another.

"After all these days, we've all learned this new spell, and you haven't even learned to swim?" Harry scoffed, wiping the water off his face.

"You can't outrun me in the water anyway, do you have to make a fuss?" Roger unceremoniously replied to him on the shore.

Once on the shore, Hermione wiped the water droplets on her body and asked curiously, "Roger, are you sure the merfolk will kidnap the people we care about the most? Except for Ginny's brother, who is still in school, he is either an only child or a Muggle-born wizard..."

"And no one has made a few friends~" Roger raised his eyebrows proudly, took over the conversation and said, "But what I'm talking about is that hostages are just one of the greater possibilities... Besides, the Golden Egg mentions 'snatching your most beloved treasure' and 'taking back the objects we took', and it may not be human..."

Anyway, he didn't believe that Old Deng would find his aunt or Caroline and throw him into the water, because any magic school takes the concealment of its position quite seriously.

Hogwarts may not be too wary of wizards, but it's completely impossible for Muggles to get in here, not to mention the fact that they can't be marked on the map, and the powerful Muggle Exorcism Charm alone can't be turned off like the Anti-Apparition Charm. Spells to expel Muggles are permanent.

"Beloved baby?" Ginny tilted her head and wiped her hair with a towel, "What could it be?"

"Your words... Probably a picture of Harry from a photo album?" Roger raised an eyebrow at the girl with a wicked smile.

I thought that Ginny would retort loudly, but I didn't expect this girl's face to immediately become bitter...

Even Harry was shocked: "Hey, hey... What do you mean by that? It makes me panic..."

"A person who has been running for a long time after drinking, and you blame me if you have fruit photos?" Ginny whispered.

Harry pulled his face and glanced at Roger with an unkind expression.
