"Shall we swim over like this?" Canaan asked, standing on the edge of the Black Lake, as he watched Dumbledore put a water avoidance charm on his head.

It's September and the temperature in the UK has dropped to around 15 degrees Celsius. Not to mention the freezing coldness of the lake, even swimming from here to the center of the Black Lake is a very laborious task.

"We can't find the merfolk's nest by rowing boat, they live in the deepest part of the Black Lake, and you can only find them by swimming through the water. Dumbledore explained, smiling at Canaan again, "Do you need me to give you a water avoidance charm?"

"Oh, no, I'll do it myself. Canaan shook his head, conjuring his wand and casting a water spell on himself. After thinking about it, he put a heat preservation spell and a dehumidification spell on himself...

Looking at the heavily armed Canaan, Dumbledore smiled: "Let's go, go there and listen to my command, no matter what happens, don't be the first to attack, they are very sensitive to this." ”

Canaan nodded, then jumped into the water with Dumbledore.

The lake was clear, the sand and gravel in the water were clearly visible, and the tangled black aquatic plants formed a dense jungle, and Dumbledore pulled Canaan through the water quickly.

They swam to a very large ditch, which was already dozens of meters deep, and the light was very dim.

Dumbledore pulled out his wand and waved it gently in the water, an ancient golden text slowly forming at the tip of the wand.

"It's an ancient contract magic. Dumbledore explained to Canaan through the Water Retention Charm.

From time to time, two mermaids in the distance with tridents swam quickly along the trench.

When they saw Canaan beside Dumbledore, they immediately looked frightened and raised their weapons as if they were facing a great enemy.

It seems that it was last night, and the powerful forces of Canaan and Pikachu left them with indelible memories.

Dumbledore hurriedly waved his wand in the water, writing a string of merfolk text.

"I'm Dumbledore, the current Headmaster of Hogwarts, and I need to meet your Matriarch. Next to me is my student, he won't hurt you. ”

After the two mermaids saw the words, they let down their guard a little. They exchanged face-to-face conversations, then nodded at Dumbledore and led the way.

The merfolk were very fast underwater, and Dumbledore pulled Canaan and kept using his wand to speed up to keep up with them.

They made their way through several black caves, turning left and right among the aquatic weeds until they reached the merfolk's nest.

It is a concave plain entrenched under water, where plants of various colors are fluorescent, and rows of circular buildings like turtle shells are arranged in an orderly manner, which looks very spectacular from a distance.

I can't believe this is where the merfolk live!

Seeing the look of surprise in Canaan's eyes, Dumbledore slowly explained, "According to historical records, the merfolk have lived in the Black Lake for at least thousands of years. In antiquity, they were also a very intelligent race, do not underestimate them. ”

As if sensing the breath of the living, more and more merfolk emerged from the building, looking at Dumbledore and Canaan.

Canaan saw a number of merfolk with female features, wrapped in unknown aquatic weeds, and surrounded by several small juveniles.

Although the merfolk were unsightly, Canaan could still see a curious, innocent look in their eyes.

"Mermaids are actually similar to us humans, the male mermaid has a violent personality and is responsible for going out hunting, while the female mermaid has a gentle personality and generally only stays at home to take care of her children. ”

"Of course, the first time we meet, if you want to express our friendliness, you can do that. As he spoke, Dumbledore opened his arms, bent down, and saluted the merfolk who were watching. He moves like a penguin in heat.

"This is a unique way of greeting the mermaids. Dumbledore added.

Although he felt that this action was a bit funny, Canaan followed Dumbledore in doing so.

Their actions seemed to win the favor of the merfolk, when a young female little mermaid swam over with her tail wagging and handed Canaan a bunch of blue aquatic plants.

Seeing this, Dumbledore smiled, "Looks like she likes you very much." This is a mermaid grass that is a specialty of the Black Lake, and it is very rare. Dry the herb and light it by the lake, and the merfolk will hear the news and you'll get their help. ”

Canaan was content to accept the mermaid grass, then cast a water avoidance charm on the storage bag, and took out a shiny gem from it and handed it to the female little mermaid as a gift in return.

This gemstone is an alchemical work of Guvet that can always emit a colorful light and is popular with many children.

The little female was so fond of the gem that she made a penguin salute to Canaan, then happily swam back to her mother, holding it up and showing it to her friends.

Canaan and Dumbledore then continued to follow the two merfolk through the merfolk colony's gathering place to a tall cavern.

The cave is inlaid with a lot of precious stones, which is very magnanimous. And it's heavily guarded, with schools of merfolk parading around with weapons in hand.

The two merfolk approached the merfolk and led them into the cave.

Walking into this, Canaan found that the space inside was large and the decoration was more extravagant.

"Albus Dumbledore, long time no see!" A strange tone came from ahead, and a tall mermaid swam in front of him with a silver trident.

"Your Majesty, it's a pleasure to see you. Dumbledore saluted.

"What are you here for, why did you bring a little wizard here? Could it be that Hogwarts is about to change headmasters again?" said Beatan, looking at Canaan with bulging eyes.

"I think I can hold up a few more years in the position of principal. Dumbledore smiled and asked, "You should know what I came for, the new Hogwarts students were attacked by merfolk last night while they were entering school. ”

"Albus, I'm very sorry for this, but recently our people have been running out of food, and all of them like to go to the lake to hunt for food, and they happen to meet your new students, and there is a conflict in the future. ”

"Moreover, you Hogwarts freshmen did the first thing, and many of my people have suffered heavy casualties, and they are still in bed. Beatan said with a sad face.

Dumbledore nodded and said in a deep voice, "Your Majesty Pit, I'm also very sorry for this matter. I don't think it's time to find out who is at fault, but to find out why it happened so that it doesn't happen again. ”
