Summer has really come, and Anna, who was swinging on the Black Lake in Hagrid's small wooden boat, is very aware of this. The boat has slowly come to the center of the Black Lake, and the cool and humid wind is mixed with some aquatic animals. The smell surrounded people, and then quietly left with the tossing heat.

Occasionally going out to go boating is actually a very good pastime, Anna thought so.

In the middle of the black lake, you can enjoy the distant scenery very well. When you first came to school, you saw the castle in the night from the lake. It was mysterious and beautiful. Now it seems that it is different to appreciate it in the daytime.

Hogwarts Castle is an ancient building with a full sense of layers built by the lake. When the snow on the distant mountains is completely wiped off, and the warm sunshine comes through the cotton candy-like clouds to kiss the spiers of the castle, everything will be smooth. With the addition of a magic filter to enhance the color, only those lucky enough to drink five or six bottles of Felicia have the opportunity to see this beauty.

George, who was sweating all over rowing, obviously didn't have the spare money to drink five or six bottles of Felix Elixir. He was jolted by the wind, then raised his head, and saw Anna with her hands folded on her lap, sitting very ladylike on the back of the boat. The location, looking into the distance with eyes full of spirit, a pair of \'summer is here, I love nature, I love the world,\'with emotion.

"It's probably almost here," George touched Fred who was sitting next to him with his elbow, "We can start now, let's take out the things first."

Fred took a cloth bag from one of the five interlayer pockets on the inside right side of the robe near the shoulder, opened it mysteriously, and showed the contents.

"Gill grass?" Anna was attracted. She knew the gill grass, but it was the first time she saw the real thing. The most in-depth knowledge she had of this plant before was just an assignment that required her to write it down with a quill pen. There are three possible colors of the saccharomyces.

That group of sticky, squashed rat-tail-like plants, after eating, can make people grow gills for underwater breathing for a short time, and webbed hands and feet for swimming.

Gill grass can be gray-green, dark blue, and some can be purple-gray. Different colors of gill grass can make people grow webs of different colors. It is very common knowledge, but Anna relied on this The little knowledge I found in the book made me get a good grade in my homework.

"Wait," Anna frowned and stared at the twins who were devouring the gill grass. "Isn't this a bit different from our plan? Couldn't it be to lure that squid out of the lake?"

Although Anna wasn't at all surprised that 'the Weasley twins' plans were a bit different'.

"Anna, look here, there are no storms, no huge waves, and no pirate ships that will fall apart at any time. It doesn't seem like a time when giant squid will come and go." Fred stuffed Anna with a handful of gill grass, "so Let's go into the water and take the initiative."

Anna squeezed the gill grass in her hand, the disgusting and slippery feeling made her admire the twins who were eating hard, "Where did you get these herbs?"

Fred and George said in unison, "I got it from Percy's girlfriend!"

At this moment, Fred and George seemed to be turned into yelling melons. Anna leaned over with interest, "Does he have a girlfriend? Who is it? Do I know him?"

"Penelot of Ravenclaw, we met together." George stopped stuffing gill grass in his mouth, and waved his arms exaggeratedly, "that is a beautiful and wise little lady." …I bet our poor brother spends most of his time in books full of words and never saw a girl prettier than those models in Playwitch magazine."

George, how old are you, why did you start reading magazines like "Flower Wizard" that are not suitable for children at first sight?

"Percy is totally obsessed with her," Fred nodded in agreement, with a beating look on his face, as if talking about his brother's new girlfriend is a way to show his maturity, " We saw Percy and Penello sneaking out for a night out, Percy clutching flowers, nervous like a bad flower thief..."

While talking, Fred suddenly felt itchy arms. Looking down, he found that he had grown a few scattered scales, and gray-green webs appeared between his fingers. He was quite excited to show George and Anna his changes.

George urged Anna to quickly eat the gill grass, "I heard from Penello that these herbs can last for more than an hour, we just need to emerge from the bottom of the water before we suffocate!"

While enduring George's nonsense literature, Anna put gills into her mouth. These unsatisfactory plants tasted good when they were eaten, like taro milk tea those waves.

Soon there was a burst of pain on the neck near the back of the ears. Anna touched the painful place, which reminded her of when she had mumps before. a thin crack...

The suffocation feeling of being covered by a pillow followed, and Fred's expression changed after he ate the gill grass first. He hurriedly leaned half of his body into the lake, and stretched out his arms a few seconds later. Watching George and Anna give a thumbs up, they plunged into the lake.

George and Anna followed closely behind.

The first thing she felt was the icy lake water, and then the resistance of the clothes. Anna opened her eyes in the water, and easily saw George who was close to her. possible local soreness.

The world in the water was similar to what she usually saw in the Slytherin lounge, but it seemed to be brighter. This may be the special effect brought by the gill grass. Anna stretched out her hand, and she found that the skin on her hand was slightly tingling. green.

It was amazing. Anna stared at her hand, and then suddenly realized something even more amazing—she was breathing in water now, and she could clearly feel the function of her newly grown gills.

Anna's exclamation was quickly interrupted, a hand grabbed her arm, and she trembled in fright. Fred rushed out from Anna, gesticulating something excitedly, but unfortunately Anna couldn't understand.

George understood it, and became equally excited. The two dived deeper, then turned around and gestured to Anna to follow.

They dived deeper and deeper, and some small fish passed through Anna's long hair sensitively, but some of them were caught by the long hair net. Rescue it, or she will go back with a head full of fish in a while.

Fred threw a ball of waterweed at George's face, and George stuffed an arm-long fish into Fred's pants, and the two of them seemed to have completely forgotten the purpose of going into the water, because the current experience is indeed so much fun.

But soon they will realize the meaning of \'don't swim in the lake in summer\'.

"Goo!" Fred spit out a bubble, his face panicked, and he began to struggle.

A pair of slender green withered claws grabbed his ankles, and the four-centimeter-long manicure could easily dig out Fred's flesh with a little effort.

It was an angry Grindylow, and it was quite normal for it to appear here. This unlucky creature that lives in the aquatic plants has just been destroyed by Fred, and then robbed of the rations that are about to be obtained by George. — that fish stuffed down someone's pants.

"Hey!" This green water monster with horns almost turned pink from anger, and its tentacles like little octopus began to wave wildly.

Terrified, George hurried to draw out his wand, and was grabbed by another Grindylow who suddenly appeared and dragged him to the bottom of the lake.

Two muffled bangs sounded abruptly, and Fred and George instantly felt that Grindylow, who was holding them, seemed to have no strength.

Anna rubbed her iron fist, and then showed her biceps with a sense of security, although there were no muscles there.

Reliable, Fred and George gave thumbs up.

But then came greater danger. They had approached the bottom of the lake unknowingly, and a group of dark shadows hidden under the rocks began to move.

But before the shadow could make a move, a mermaid suddenly appeared—everyone was startled when the big face appeared.

"What did you do to my pet!?" The hoarse female voice questioned. The mermaid lady who just appeared looked very angry. Her iron-gray skin was slightly reddened by anger, and her dark green hair seemed to be turning into a sharp knife at any time. Plunge into the verdant gall of these invaders before you.

The creator of the magical world seems to be particularly dissatisfied with the mermaids in the freshwater lake~lightnovelpub.net~ The big orange eyes, sharp teeth, thick lips and extremely intimidating body shape are not related to beauty. Underneath, those mermaids in the sea are much more beautiful, and there are also saltwater mermaids who once kidnapped a prince and went home by cheating.

"Pet? Ma'am! Did we have some misunderstanding!?" George tried to explain, but there were two bubbles in one mouth, and he couldn't make a sound at all.

The mermaid lady took off the pebbles strung up with a thick rope around her neck, and shook them in front of the three of them, and then a Grindyllo was sucked over—it was one of the ones knocked over by Anna. It is only now discovered that Grindylow's fingernails have been manicured, which is enough to prove his identity as a domestic pet.

"Oh! My poor baby!" The mermaid lady opened her huge mouth to the unconscious Grindylow, and kissed the poor little thing's forehead, almost biting off its head, "How can you What a crime!"

"It really suffered..." Fred looked at the giant kiss of the mermaid lady with palpitations, and complained softly, and there were still two bubbles when he blew out.

Unfortunately, the mermaid lady seemed to have a special way to know what the bubbles of the humans in the water were talking about, so she snorted, glanced at the vigilant Anna and the terrified George, and then stretched out her hand. He grabbed Fred and dragged him in the direction of many boulders, "You bunch of people who are not fish - there must be a price!"

Anna took out her wand, spitting bubbles and yelling, "Let him go!" But the mermaid lady didn't stop, but showed a terrified expression when she saw the wand, and swam faster.

Anna couldn't aim, so she and George chased after the mermaid.
