Being at Hogwarts, something's not right with this system.

To Lin Yu's surprise, he hadn't even officially started fishing yet, hadn't even put the bait on the hook, and was just thinking about teasing his little girlfriend.

Surprisingly, the fish hook took the bait!

That's outrageous, isn't it?

He was joking; he's not really Jiang Ziya.

Besides, Jiang Taigong wasn't fishing for fish; "willing people take the bait" refers to people.

But now that he'd taken the bait, Lin Yu wasn't going to let go. So, without bothering to tease Hermione any longer, he pulled her up forcefully.

With a splash, something was pulled up from the lake.

It should be noted that Lin Yu possesses a Chaotic Dao Body and a cultivation level of the fifth level of Qi Refining. Despite his appearance as a child, he actually harbors terrifying power within him.

"What is this?" Hermione, who was almost sitting in Lin Yu's lap, turned her head to look and exclaimed in surprise and uncertainty.

Lin Yu looked down and saw an ugly mermaid with a fish tail on its lower body but a human torso on its upper body. It had dark green, messy, seaweed-like hair, iron-gray skin, and yellow eyes, and was glaring at them fiercely.

This is a mermaid.

However, this is not a mermaid, because he is not beautiful at all.

However, when Lin Yu recalled a certain black merman from his previous life, it seemed that not all mermaids were mermaids.

Suddenly, the mermaid in front of them opened its mouth, revealing a mouthful of yellow teeth with sharp, thorn-like teeth, and made a piercing sound.

The sound was as unpleasant as scratching a blackboard with sharp claws.

Lin Yu frowned; his five senses were heightened, making the sound even more jarring.

Hermione also looked distressed.

"Shut up," Lin Yu shouted, "or I'll roast you."

Don't forget, he's not exactly known for his good temper.

The merman actually shut up. He looked coldly at Lin Yu, then raised his hand.

Lin Yu then noticed that the mermaid was holding a fork, just like a harpoon.

Lin Yu had always found it strange that in many worlds, the weapons of these aquatic creatures were mostly harpoons.

Do they want to stab themselves in the back?

As they thought this, Lin Yu immediately drew his wand, as did Hermione. The two of them warily watched the merman in front of them, knowing that if he were to attack them, they would be met with the magic of the two young wizards.

Not to mention that Lin Yu already had spiritual energy circulating within his body. If magic didn't work, he could still use the fishing rod as a 'sword' to unleash a terrifying sword move and kill the mermaid.

Fortunately, the mermaid did not do anything unwise. Instead, he pointed the harpoon at his head, or rather, his hair.

Lin Yu then noticed that the fishhook hadn't actually caught the mermaid, but rather hooked onto her hair.

The mermaid's hair was so messy, tangled and knotted in many places, that's why it got caught on the fishhook.

He was probably patrolling in the water when he swam over here and was accidentally caught by Lin Yu.

No wonder the mermaid looked so angry.

What did he do to deserve this? He was just patrolling his territory when someone pulled him out of the water.

And how come this human brat is so strong? He didn't even have time to react before he was caught in the act.

Lin Yu blinked and said awkwardly, "I don't know if you can understand what I'm saying. I'll help you remove the fishhook now, but you can't bite me. Otherwise, I'll have to take action."

The mermaid wanted to nod, but the fishhook was holding him up, making it difficult for him to do so.

He could only blink.

Lin Yu and Hermione exchanged a glance, but Hermione said, "Put him down and let him untie himself in the water."

It seems Hermione is also worried that if Lin Yu reaches out, the mermaid will bite him.

Lin Yu nodded, and while letting the broom fall a little, he lowered the fishing rod in his hand towards the water.

The two remained at peace until the mermaid slowly sank to the surface of the lake.

A moment later, Lin Yu felt the fishing rod become lighter, knowing that the mermaid had unhooked the fish and was about to ride away on her broom when...

On the lake, the mermaid poked her head out again and pointed downwards.

Lin Yu and Hermione looked at each other in confusion.

The mermaid opened her mouth again and let out a short, piercing scream.

Lin Yu, having seen the movie, seemed to recall something and said to Hermione, "Mermaids can't talk on water, so it seems he wants us to go underwater?"

Hermione, however, felt uneasy: "Are we really going to listen to him? What if he wants to hurt us?"

The water is the mermaid's domain.

Lin Yu said nonchalantly, "It doesn't matter. Don't forget we're still cultivators. Even if we can't use magic, he can't threaten us."

Moreover, Lin Yu also possesses the Nine Forms of Cloud Abyss, as well as Tai Chi Chuan and Tai Chi Sword.

If this mermaid really had any inappropriate thoughts, he would stew her in his alchemy furnace.

No, the alchemy furnace is for baking, just like an oven.

How about we have the roasted mermaid?

Are mermaids human or magical creatures?

Lin Yu shook his head. He decided to put all that aside for now and find out what the mermaid was up to.

Relying on his superior skills and daring, Lin Yu put one arm around Hermione, put away his wand, and silently took out the Cloud Storm Sword from his Qiankun Ring.

At this point, Lin Yu had more faith in his own cultivation level than in magic.

Of course, he also put away his fishing rod, ready to take out his wand again at any time.

Hermione saw that Lin Yu had made his decision and didn't say anything more. She believed in his decision and trusted it unconditionally.

At worst, it's two against one; what are they afraid of, a mermaid?

With a thought, Lin Yu put the broom into his Qiankun Ring, and he and Hermione fell into the Black Lake with a "plop".

The next instant, the mermaid sank into the lake and swam to Lin Yu and Hermione, pulling them both into the water.

So, you really harbor ill intentions?

Demon, take this!

Lin Yu raised the Cloud Mist Sword in his hand, and his spiritual energy circulated rapidly within his body, ready to make a move.

However, the mermaids did not attack them. Instead, they spoke in human language: "Don't be afraid, little wizards. We mermaids cannot speak on land; you can only hear us in the water."

Mermaids are aquatic creatures who speak in the water all year round and have become accustomed to the pressure of the water.

After all, water is a more viscous substance than air, so it takes more effort to speak.

This causes the sound they make to be heard to be "louder" in the air after they leave the water, making it harsher.

This explanation seems reasonable, doesn't it?

The mermaid continued, "Although the process wasn't very pleasant, let's get to know each other. I am the leader of our tribe; you can call me Merkus. And I am female."

It turns out that Hermione and Lin Yu had always mistaken her for a man, and in English words, the male and female pronouns 'ta' can be distinguished.

Mermaids actually have their own language, but this mermaid leader has mastered human language.

Or did she learn English?

Now, Merkus wandered up to Lin Yu and Hermione and asked, "I should ask you two, why aren't you staying in Hogwarts Castle? Why did you come to our Black Lake? And you even managed to fish me out?"
