"What is this?" Roger screamed, and by the faint moonlight he could faintly see what appeared to be a human head under the water.

Canaan also held his wand like a small sun and stretched out his head to look, only to see countless black shadows shuttling under the lake.

As if attracted by the light on Canaan's wand, they emerged from the water one by one, densely packed and staring at Canaan with a stern expression.

They have humanoid features, but their eyes are large, their noses are flat, and their appearance is very ugly.

"Hell, what are these things?" said Roger, horrified, he had never seen such an ugly creature. And there are so many of them that they don't look ill-intentioned.

"It's a merfolk!" Alita quickly explained, frowning slightly. The creatures were exactly the same as the pictures she had seen in the books.

"What do they want to do?" Roger asked.

Alita shook her head, these creatures are no less intelligent than humans, and no one knows what they want to do.

"Don't be nervous, they're mermaids, they have an agreement with our school, and they won't hurt us easily. Hagrid exclaimed.

In the years since Hogwarts was founded, there have never been incidents of merfolk actively attacking students, and they have sometimes helped Hogwarts defend itself against outside enemies.

However, there are always those who can't suppress their fears, and a new student with blonde hair raises a trembling wand and shouts, "Die, monster!"

A white light shot out from the tip of the staff, instantly knocking a merfolk deep into the lake.

"Damn, this sucks!" Hagrid slapped his head hard at the sight.

An unpleasant roar came from under the lake, as if to give orders, and the merfolk on the surface also roared, and after baring their fangs, they burrowed back to the unfathomable depths of the lake.

"Get out your wand, get out your wand!" Hagrid shouted hurriedly. He knew that the merfolk were angry, and that this was a prelude to an attack.

Unfortunately, most of the freshmen apparently didn't have any magic skills, and they even had a strange way of holding their wands, and a few even accidentally dropped their wands into the water.

Many of the freshmen panicked, and the situation looked very bad.

At this time, the merfolk attacked, some of them dangling the wooden boat underwater, and some of them came to the surface to pull the little wizard.

"Faint!" Alita was the first to attack.

The white spell blinded the fish-man who had just appeared on the spot, and it shook its head, revealing a hideous face, unaffected by the spell in the slightest.

It swam swiftly towards Alita, wanting to show the little human girl the merfolk's wrath.

"Faint!"

However, before it could get close to the wooden boat, another white light came quickly, and it only felt that it was churning, as if it had been struck with a jack of sticks, and then fell to the bottom of the lake, unconscious.

This spell was cast by Canaan, and his current mana value has reached more than two hundred points, which is stronger than the magic of many adult wizards. It's just a basic stun spell, and the power should not be underestimated.

After casting this spell, Canaan had no intention of stopping, he kept waving his wand, and white light shot out from the tip of his wand, quickly emptying the merfolk in the nearby waters.

Alita looked up at Canaan, slightly stunned, she didn't expect this boy of her age to have this kind of strength. These murderous fishmen seemed to be vulnerable in his hands.

But the cries of the young wizards around her quickly woke her up, and she couldn't help but clench her wand and plunge into the fight.

At this time, Hagrid also exposed the wand in the little red umbrella, which shimmered white, and kept cleaning up the merfolk floating on the water. There was a group of merfolk who tried to overturn his boat, but they did not make it shake in the slightest bit.

"Die!" said the blonde freshman angrily at the merfolk surrounding him, his wand in his hand not stopping. I don't know if it's a mermaid who holds a grudge, and there are a lot of merfolk who come to attack him.

But he obviously didn't have much magic power, and after a few powerful attacks, his magic power dried up a bit. So he threw his wand in the cabin, threw up his hands, and slammed his fist at the merfolk.

His fellow shipmates were also very heroic, they used wands as weapons, and one even stuck his hard thorn wand into the mermaid's eye, splattering a large amount of blood, the scene was very bloody!

However, there are more and more mermaids gathered around, and it seems to be endless.

Gradually Canaan also felt very struggling, and he could not take care of all the new births. Unless he exposes Kama Taj's magic, he may be able to calm the crisis quickly, but it is clear that Kama Taj's magic cannot be easily exposed.

"If you really can't do it, you can only use the infratone ball!" Canaan thought anxiously. However, the infratone ball will be more powerful in the water, and it may not only injure the newborn by mistake, but also directly kill the mermaid in the water who is extremely sensitive to sound.

After all, the first person to do it was a freshman, and the purpose of the mermaids surrounding them was not clear, and Canaan didn't want to directly exterminate the mermaids.

At this time, Pikachu, who felt that the situation was critical, pulled Canaan's trouser legs in the cabin, "Pika Pika!"

"What's wrong, Pikachu?" Canaan looked down.

It pointed to its tail and then to the water, "Pickup!"

"You're saying you can fix them?" Canaan frowned. Now that Pikachu is still in a juvenile state, he can't even control the electricity in his body, and Canaan really doesn't worry about letting Pikachu release the electricity in his body.

However, seeing Pikachu's insistent look, Canaan had to believe it for the time being.

"Listen to me, don't go near any mermaids, don't touch the lake!" Canaan shouted into his wand.

The loud sound overshadowed the slapping of the crowd and the mermaids, echoing throughout the Black Lake!

Many freshmen have just seen Canaan's great power and are very convinced of him. Now they heard Canaan speak, and they did as he was told.

Then Canaan hurriedly put Pikachu on the bow of the boat, took off its blackout harness and said, "Little one, it's up to you!"

Pikachu looked determined and nodded heavily.

It puffed out its cheeks, cocked its tail, and began to mobilize the long-suppressed electricity in its body.

A trace of blue electricity began to gradually surround its body, and then the current became thicker and thicker, and the air crackled!

Pikachu at this moment is like a god who controls thunder and lightning!

Canaan seemed to smell the smell of burnt in the air, and he hurriedly pulled Alita and them back quickly.

Finally, Pikachu converged the current to the tail, and a blue column of electricity tens of meters long lit up half of the sky.

Attracted by the momentum, the merfolk stopped their attacks and stared blankly at the huge electric current above their heads.

They immediately felt the danger contained in this powerful electricity, looked terrified, and hurried to escape from here.

But it's obviously too late!

"Pikachu!!" Pikachu shouted as hard as he could, quickly inserting his tail into the water.

Blue electricity quickly covered the entire surface of the lake, spreading along the lake in all directions. Everywhere the blue light went, the terrified expressions of the mermaids seemed to be frozen.

Then they fell down one after another, like dumplings in a pot, and quickly fell to the bottom of the lake, only a few lucky merfolk were not stunned by the electricity, and they swam their tails and quickly fled from here.
