"The common characteristic of the merman people is that the human body is fishtailed, and tears are turned into beads. Tears turn into pearls," saw Harry and Angelina's eyes light up at the same time, and Daphany added, "But the quality is uncertain." Harry and Angelina's gaze suddenly returned to normal. If it is a round pearl, it is naturally worth a lot of money. But if it is a pearl in poor condition, you can buy a basket for one pound at the source.

"Sharks also have a hobby, that is, they love to sing, although they are good-looking and not good-looking, but their singing skills are very good!" Daphne smashed her mouth and said, "Even the mermaid can sing, the thief is magical." It's more like a frog spirit...... Some people count Sirens and Naga Sirens as a type of merfolk, but they are not merfolk. ‘’

"Daphine, you know so much!" Harry exclaimed.

"That's it!" Daphany smirked.

"So, our third mission might have something to do with mermaids?" Angelina said with interest that Western children have heard the story of mermaids since childhood.

"I guess it has something to do with water." Harry frowned, "Well, I guess it has something to do with the Black Lake. ”

"I agree with Harry." Daphany is a little confused about this, because she's afraid of water! This project will be very unfriendly to her!

"Black Lake, I've heard that there are mermaids in Black Lake!" Angelina still hasn't forgotten about the mermaid.

"I guess it's a fish-man." Daphne unceremoniously poured cold water: "Lorelei only lives in the sea, and the Black Lake is a freshwater lake. ”

"Maybe it's a freshwater mermaid, didn't you say there are also freshwater mermaids?" Angelina said without giving up.

"There are freshwater mermaids, but never in the UK." Daphany shook her head and said, "Freshwater mermaids generally live in the inland lakes or mountains and rivers of the vast continent. At present, only discoveries have been heard of in Asia and the Americas. There are no records of freshwater mermaids found in Europe, Africa, or Oceania. ”

"Ah...... Isn't it possible at all......" Angelina looked disappointed.

"Personally, I think there is little hope." Daphine spread her hands.

"I mean, now is not the time to care about mermaids." Harry was defeated by two men: "Shouldn't we be thinking about how to get into the water now?" We don't have gills! ”

"That's not simple, a head bubble spell is solved?" Angelina said with a nonchalant expression.

Really! Daphany pouted secretly. The first thing that came to mind when the little wizards thought of going into the water was the head bubble charm. It's a spell that middle and upper yearlings can learn in Charms class - well, Harry and Daphany are only in their fourth year and haven't learned it yet. But Devany naturally mastered it a long time ago.

The head bubble spell can effectively solve the problem of underwater breathing. But that's about it. The occasional scuba diving is certainly more than enough. But it would be a matter of course to find something or a place in the black lake of Nuoda.

The Black Lake is twenty or thirty kilometers long and wide, and the deepest part is said to be two or three hundred meters. Finding something in this range is not an ordinary difficulty. Wanting to swim a lap is a big problem!

There are a lot of messes in the Black Lake besides mermaids.

1. Giant squid!

The giant squid in the Black Lagoon is said to be Godric Gryffindor's friend - Godric Gryffindor's Animagus is the giant squid, the largest known Animagus in the wizarding world. Daphne's Bird Snake could theoretically surpass that size, but the mana cost would be astronomical. The giant squid is said to be Godric Gryffindor's metamorphosed friend or offspring - Daphany is not without malice, as if it could be a girlfriend or a descendant of the carryover.

The giant in the black lake is in a semi-domesticated state, and sometimes it will go to the shallows and the sun, and the passing students will find that there have been no injuries in the past. Last year, Colin Creevey's younger brother, Dennis Creevey, accidentally fell into the water while sailing to the castle and was carried up by him. So it's scary, but it's not dangerous.

2. Fishman!

The fish-men didn't like the wizards to bother, but wanted to have a deal with Dumbledore. There is nothing dangerous either.

3. Grindy Lowe!

A small water monster with horns and a pale green body. Lupin explained it in class when he was in third grade. It is widely found in lakes throughout Europe, and the combat effectiveness of individuals is very scummy, but this thing lives in groups, and it is often one hundred and eighty.

Grindillo in the Black Lake is said to have been subdued by the merfolk there, and he doesn't know if it's true or not. But even if it's true, they're just obedient or jealous of the merfolk. Muggles or wizards entered, and it was almost impossible for such inferior, purely instinctive creatures to restrain their desire to attack. Tsinghua

4. Horse-shaped water monsters!

There is a small herd of horse-type water monsters in the Black Lake, and the total number is about twenty. This is a four-star dangerous creature! Thankfully, they all live on the far side of the Black Lagoon away from the castle - presumably banished by the wizards. It is not uncommon to hear rumors of Muggles being tricked into riding on horses and then eating them.

5. Kaba!

The kappa in the Muggle story looks like a monkey, but covered in fish scales instead of fur. It has a hole in the top of its head that can hold water. Kaba will aggressively attack Muggles or wizards, and likes to suck human blood. This creature was originally Japanese, but it was introduced by high-ranking officials of the Ministry of Magic who didn't know that time, and now there are quite a few in the waters of the United Kingdom. It's also a four-star dangerous creature!

As for the aggressive fish in the water, Daphany knows more than five. A little further from the castle, there was Hagrid's smuggler, but many people knew about a nest of fire crabs he raised. Fire crabs live on land, but they also like to go into the water......

Hearing Daphine say the same, Harry and Angelina's faces turned a little green. Especially Harry.

Angelina had no contact with the four-star dangerous magical creatures - although both the Kaba and the Horse Monster were explained by Professor Lupin last year, Lupin did not bring them to class due to the danger. Four-star dangerous creatures are completely different from Pomlock, Red Hat, and the like, while three-star dangerous creatures are completely different.

Unlike Angelina, Harry has really faced dangerous creatures from four stars.

The following year, Harry, Dafanie and Ron were told about Hagrid's "follow the spider" and entered the Forbidden Forest, where they were almost treated as a snack by the Eight-Eyed Spider. Daphany frightens the eight-eyed spider with fire, but as they leave, they are attacked by a bird-like man-eater in the Forbidden Forest.

At that time, Daphany was only able to repel the bird-type man-eater for a short time with the help of Harry and Ron, but it was only repelled, not defeated!

Although Harry has made rapid progress in recent years, his self-evaluation may not be as good as that of Daphany in the second year. At least he won't be able to use the fire spell yet.

Seeing that the faces of the bluffed two turned green, Daphany felt that it was a little too much. So he turned to reassure: "I'm just saying the worst case, in fact, the horse-shaped monsters are all at the far end of the black lake, and it is basically impossible to encounter them." There are no two Kaba, and if there are three, or five. It's also not easy to bump into it. And since this project is related to merfolk, I guess it's likely to be within the merfolk's sphere of influence. The merfolk don't like this kind of thing, and nine times out of ten they have been driven to other places. In all likelihood, what we're really dealing with is just some aggressive fish and Grindy Lowe. ”

"Is that so?" Both Harry and Angelina looked at Daphany expectantly, and the latter nodded. After thinking about it, he said: "But even those aggressive fish and Grindillo may not be easy to deal with." They are very fast in the water, and our mobility and magic are often diminished in the water. ”

"What's the solution?" Angelina asked, a little uneasy. After listening to Daphne's words, she also understood that it was a little too simple to think at first. After all, this is the number one event in the wizarding world! Just because the first two projects went well doesn't mean you can't underestimate it.

"The Head Bubble Charm is definitely needed, but Angelina has mastered it!" Daphany pretended to think as she said, "Harry, this magic is very simple, I'll teach you now, you practice it, and try to master it today." ”

With that, Daphany briefly demonstrated the head bubble charm to Harry.

With Daphine's spell and the standard wand swing, a bubble slightly larger than her head appeared, enveloping her entire head.

Daphne didn't need to be so troublesome, she could now unleash this level of magic with just a casual gesture. As long as the magic and mental power are strong enough and you are familiar enough with magic, many magic skills don't actually need to be used exactly according to the rules. For example, Levitation, which Daphne now uses with either a spell or a wand, can be used with her hand raised.

In fact, she did just that in the second project. Amazed the judges, and then deducted points......

However, Harry didn't have the skills, and he still needed to summon magic step by step. Fortunately, due to Daphne's intentional or unintentional training, and Harry's talent is indeed in place. Nowadays, the foundation of magic and magic is very solid. After two or three attempts, you can already summon a large bubble that covers your entire head.

Harry had actually seen the Bubble Charm. One of the Weasley brothers' products in the past two years was banned by the wizarding schools of Hogwarts and the entire wizarding world as soon as it was launched - dung eggs!

It was something that could emit a disgusting stench that would dissipate in a few seconds, but those few seconds were absolutely painful and scary to think about—yes, Harry had faced it.

At that time, he saw that the senior classmates used their heads to soak the spell for the first time to avoid irrepressible damage to their olfactory organs.

"The head bubble spell that covers the entire head is actually the basic version!" Daphany was pleased with Harry's progress and smiled and raised her requirements: "Although it works well, it often affects the movement underwater. And it's also easier to break if it's too big. It's best to shrink it down to just your mouth and nose! ”

Daphne said, waving her wand again, this time more casually. A small, long strip of bubbles covering only her mouth and nose appears on Dauphanie's face.

Daphne then dismantled the spell: "As long as you think carefully about the area you want to envelop when you summon it, you can expand or shrink." It can even wrap the whole body. But then you can't move. Protect your mouth and nose, protect your breathing, and bring a pair of goggles when the time comes, and there will be no problems underwater! ”

Not only Harry, but even Angelina nodded repeatedly. She had only mastered the Head Bubble Charm before. After all, this magic is not usually used that much.
