A magical journey that begins in Azkaban

"Ahem~" Rogge grabbed Daphne's hand that was touching up, "Don't touch it!"

"But..." Daphne's cheeks were like red-hot irons, and stars were shining in her eyes: "But you are so cute!"

"Roger, I really want to take a picture of your current appearance and make it into a pillow!" Daphne couldn't wait to hug her. Rogge's beautiful appearance fulfilled all her fantasies about mermaids.

"Stop! I'm a man... okay, I'm a fish!" Rogge solemnly warned Daphne, "Be more reserved, my Miss Greengrass! The duration of the potion is 4 hours. If I use it after 2 hours, If you don’t come up, go find the professor and save me.”

Rogge rolled his eyes at her and warned her not to act recklessly. He took a deep breath and began to simulate in his mind.

【1】You discovered the mermaid tribe at the bottom of the Black Lake;

【2】The mermaid found you and kidnapped you back to the village;

【3】After some explanation, they determined that you were a little wizard and let you go.

...(stop simulation)

Seeing that there was no big problem, Rogge leaned back and got into the black lake.

"Roger! The rope..." Daphne pouted and looked at the rope in her hand, which slipped from the fish's tail. She shouted hurriedly, but it was too late, Rogge had disappeared into the water, and she could only watch helplessly.

"Is everything going to be okay?" She stared at the silent black lake, praying that Rogge would not be in danger. Looking at the excess potion on the shore, Daphne stamped her foot and drank the potion without hesitation.

In an instant, she felt a strange change occur in her body. She had turned into a mermaid and dived into the water gracefully with a flick of her tail.

Under water, Rogge quickly discovered the flaw in the potion. It allowed the wizard to breathe but not speak. When he opened his mouth, he could only spit out a string of bubbles.

After swimming for a while, he discovered a dense kelp forest to the west of the Black Lake. According to the professor, the mermaid tribe is in the middle of the kelp forest.

He swung his increasingly familiar fish tail and got into the seaweed. Follow the flickering light in the distance and swim inside. After quietly approaching, it turns out that there is a mermaid tribe.

The village is built with large and small stones, and yellow-haired mermaids shuttle in and out. They looked like Professor Sprout's drawings, and they looked very scary.

Soon, he saw the target of his trip outside the village. A large area of ​​fluorescent waterweed swayed at the bottom of the lake. In order to prevent being caught by the mermaid, Rogge prepared to dive down and wrapped himself in mud as a disguise. Before he could take action, his head suddenly sank and he fell into coma.

The mermaid Mercus looked at the sinking Rogge, gently swung his tail, and caught him back to the village.

"Wake up, wake up!" The mermaids swam around him, chatting away like their distant cousin Rogge.

They were at least seven feet long, making the little wizard look like a newborn mermaid in comparison. Their voices are so beautiful, they sound like sopranos singing, very transparent.

"Chief, he is so beautiful! But he is a little too small."

"Yes, yes, did Principal Dumbledore capture him from the Caribbean?"

"Definitely! Look at his skin and hair?" The somewhat restless mermaid said, moving her hands and touching here and there.

"Why are we so ugly?"

"You forget, we live in cold water."

"Oh, yes, yes!" She swam over and touched Roger's smooth face, then touched her own, and sighed: "The Mero tribe in Ireland is uglier than us."

"Okay!" The leader Merkus asked them to go back. She was taller and looked very fierce.

"This is a young wizard from Hogwarts, not one of our kind."

Rogge nodded quickly, pointed to his mouth, and took out his wand to prove his identity.

"Hey, has the wizard mastered the method of turning into a mermaid? Then can we become humans?"

"Did you read any Muggle books in the wreck again?"

Merkus didn't pay attention to the comments of the tribe behind her. She frowned and asked, "Little wizard, what is your purpose of trespassing on our territory?"

Rogge opened his mouth to explain, and only a string of bubbles came out, causing the onlookers to laugh in an aria version.

Rogge had no choice but to make a "friend" gesture, and then pointed to the waterweed over there, indicating that he was here to collect it.

Merkus thought for a moment and said, "Come with me. Next time you invade our territory, I will show no mercy."

Rogge nodded quickly and swore that he would never come to the mermaid tribe even if he starved to death or jumped from the tower.

"Take the waterweed and go." Merkus asked Rogge to pick it out at will, and threw a piece of kelp for him to tie around his waist.

Rogge paid tribute and thanked him. The mermaid seemed ferocious but still friendly. At least he didn't use the spear in his hand during the sneak attack. He breathed a sigh of relief, the task of collecting water wave grass was finally completed.

Just as they were returning to the surface, a mermaid swam over in a hurry.

"Chief, I saw a man-eating eel chasing the little mermaid." Her yellow fins trembled slightly, and her curious eyes fell on Rogge, looking up and down.

"No, it's Daphne!" Rogge immediately realized that she must have drunk the potion and came down to find him. He grabbed Merkus's fins and used various methods to try to make Merkus understand that the mermaid being chased was also a little wizard.

"You little wizards are so troublesome. No wonder Principal Dumbledore always complains to me." Merkus looked at Rogge who had a string of bubbles coming out, his voice full of depression.

She gently swung her tail and swam up, raised the spear in her hand, and sent out a series of beautiful sound waves. The sound waves spread at the bottom of the lake, causing ripples in circles.

This was a summons signal for the entire Selki tribe. Under her command, the tribesmen quickly gathered to prepare to save the little mermaid. Rogge looked at their queue and keenly noticed that the mermaid warriors were all women. Is the Selki tribe a matriarchal society?

Now was not the time to study mermaid culture, so Rogge followed Mercus and swam in the direction of the man-eating eel. He waved his arms and asked the mermaid next to him with gestures: How do you sense Daphne's location?

"The voice is our eyes." The mermaid touched Rogge's hair, her eyes full of envy. Those compatriots who live in warm water areas must be so beautiful. It's a pity that they live in the cold black lake, and the people of the tribe are becoming more and more ugly.

Merkus led everyone to quickly find the pursuer, which was a huge and terrifying black aquatic creature with a big mouth full of sharp teeth. Its tail is thick and strong, but as flexible as a snake.

Daphne swam forward desperately, but the man-eating eel was getting closer and closer to her. Feeling the swirling water behind her, she screamed in horror, but could only bubble out weakly.

"Daphne, this way!" Roger shouted nervously, but his voice still couldn't be conveyed.

"Little wizard, can you lure it here?" Merkus looked at Rogge and explained her plan: "It can't hear our voices."

Roger nodded, and the tip of his wand glowed brightly.

The darkness of the lake bottom was instantly broken, and the lake water exuded a charming and deep blue color. The man-eating eel was attracted by the sudden bright light, and its biological instinct forced it to abandon Daphne in its mouth and turn its head to swim towards the light source.

"Little wizard, make it brighter!" Mercus noticed that the man-eating eel was turning around and urged him quickly.

Rogge nodded and released more magic power without reservation. It is like a sun rising from the bottom of the lake, completely eliminating the long darkness that lasted tens of thousands of years.

Lake creatures such as Grindylow, Loba, phosphorescent jellyfish, and squid were awakened, and the fish in the sunken ship fled toward the water in panic.

Merkus was amazed. Such a level of fluorescent light was far beyond her imagination. In Hogwarts Castle, the students saw a dazzling white light on the surface of the Black Lake and couldn't wait to ask around what happened.

"I originally thought there would be a fierce battle." Mercus saw the escaping man-eating eel and said with emotion, "It's a pity that it was scared away by you."

"Let's go, I'll take you and your companions back to the surface."
