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

The twins still went to Hogsmeade.

They are in third grade this year, so they can naturally go there to play on certain Saturdays.

However, because yesterday was a Quidditch match, they missed the chance to go there, so they decided to go on an adventure today, on Sunday.

They treated defying school rules as an adventure game.

For example, they always tried to persuade Lin Yu to go play in the forbidden forest with them.

They believed that Lin Yu was also a warrior who challenged authority, after all, he wasn't even afraid of Professor Snape.

Of course, Lin Yu had his own plans, so he politely declined their invitation.

After having something to eat in the morning, Lin Yu and Hermione still went to Black Lake.

Because Hogwarts Castle is located high in the Scottish Highlands, it is colder than other places, and the Black Loch has already begun to freeze.

However, in order to complete the mission, they still rode together on a flying broom, with the light wheel carrying the two of them to the center of the lake, where they dropped fishing hooks and waited for those willing to take the bait.

Not long after, Lin Yu's fishing rod moved, and without hesitation, he pulled the hook up.

Unsurprisingly, Merkus stood with his arms crossed, staring at him expressionlessly.

"Eee-yah-yah".

Mercus opened his mouth and let out a piercing scream.

Because mermaids are used to speaking underwater, they cannot speak on the surface and would produce a piercing cry, just like this.

Hermione sat sideways, leaning against Lin Yu's shoulder, covering her ears with her hands: "Just shut her up."

Lin Yu frowned and said with a wry smile, "Stop cursing. Why do we always manage to catch you? We really came here to fish."

Merkus's insults were very vulgar, and she didn't know why; she had already moved to different areas many times.

As the leader of the mermaid race, the entire Black Lake was practically her territory.

But she also has to patrol.

But every time, Lin Yu manages to catch them.

Merkus was also helpless. Her patrol objective was to be wary of the creatures in the water, so she naturally had to look towards the bottom and swim close to the surface.

Unfortunately, Lin Yu's fishing hook ended up catching her.

Suddenly, Merkus flicked his tail, and a large fish flew out of the water.

Lin Yu reacted quickly, taking out a long steel spear from his Qiankun Ring and stabbing it into the fish's body.

Mercus's eyes lit up. He looked at his harpoon, then at the other man's steel gun, and suddenly felt uneasy.

That was Lin Yu's Dragon Gall Spear, a bonus item included in the super gift package, and a top-grade magic weapon.

Unfortunately, Lin Yu couldn't use a gun properly, so he could only use it as a harpoon.

After a "friendly" meeting, Lin Yu helped Merkus remove the fishhook, and then they went their separate ways.

"I told you I'd have to catch her," Hermione said, shrugging her shoulders and putting away her fishing rod.

It's a pity, she's in the Air Force again.

However, Hermione was not discouraged, because she knew that since she was able to catch Merkus, it meant that within the area where this mermaid leader was active, it was impossible to catch ordinary fish.

Fortunately, Merkus was somewhat polite and would always prepare a fish as a bargaining chip.

Is it considered ransom?

Lin Yu thus completed the mission and received 100,000 low-grade spirit stones as a reward.

For them now, a mere 100,000 low-grade spirit stones are no longer enough to improve their cultivation.

So the two of them, carrying the fish, rode their flying brooms back to the shore.

They arrived at Hagrid's cabin.

"Welcome, welcome," Hagrid greeted the two warmly.

Ya Ya was also very happy, jumping up and down, because it saw the fish in Lin Yu's hand and knew that it would have a good meal again today.

"This guy," Lin Yu said with a smile, reaching out to pat Ya Ya's big head. Now, Ya Ya wasn't so scary in front of him anymore.

As their cultivation levels continued to rise, their appearances also changed rapidly.

Lin Yu and Hermione now look two or three years older than their peers, more like third-grade children.

Moreover, one of them is graceful and elegant, and the other is tall and handsome; many people at Hogwarts ship them as a couple.

It's hard not to love a perfect couple, a handsome man and a beautiful woman.

Lin Yu came in, borrowed Haig's stove, and skillfully began to cook.

Hagrid assisted Lin Yu by preparing the things he needed, such as starting a fire and washing vegetables.

Soon, a large pot of delicious fish soup was freshly made.

Lin Yu also made a big pot of beef stew with potatoes.

He found it strange that the British eat beef soup and stewed potatoes, but they just don't know how to make beef stew with potatoes.

It's clearly a very simple dish, isn't it?

Perhaps they have their own unique taste buds?

However, Lin Yu's Chinese dishes were very popular; at least Dumbledore and Professor McGonagall had long been won over.

And of course, Hermione.

"Lin Yu, when Christmas comes, I'm going to take you home so my parents can try your cooking," Hermione said while sipping her fish soup.

Lin Yu was taken aback. Christmas?

It's already November, and Christmas is just over a month away.

Although Lin Yu had complained before about why Hogwarts, a magic school, also had to celebrate Christmas with its young wizards.

However, it must be said that in Western countries, Christmas is like the Lunar New Year, an unmissable holiday.

Therefore, Hogwarts also has holidays.

The only difference is that during summer vacation, the entire Hogwarts complex closes, and the children have to go home.

However, they can choose to stay at school for Christmas. For example, orphans like Lin Yu would have nowhere to go even if they wanted to.

And then there are the kids like Harry, who don't want to go back to the Dursleys' house, and they all choose to stay at school for the holidays.

Lin Yu muttered, "I didn't say I was going to your house for Christmas."

Although they had already established a relationship and dated for so long.

But he's not ready to meet his parents yet.

Hermione couldn't hold back any longer, rolling her eyes and asking, "What? You don't want to take responsibility?"

Hagrid, holding a large bowl, gave Tooth a wink and quickly moved aside to watch the fun.

They don't want to get implicated.

Lin Yu was speechless: "Big sister, how old are we?"

Is he trying to avoid responsibility? He just doesn't want to get arrested.

The father-in-law must kill him, right?

Hermione laughed angrily: "Then you still dare? And don't you know? Not only is the legal age of adulthood for wizards seventeen, but in England, as long as my parents, or guardians, agree, I can register our marriage at sixteen. Lin Yu, don't tell me you don't intend to marry me."

Lin Yu never expected that he could get married at the age of sixteen.

He truly didn't know that in Scotland, one could get married at sixteen without even needing a guardian's consent.

After all, different countries have different laws.

Some countries even allow polygamy to this day; their laws permit it, so you can't interfere, right?

Lin Yu immediately puffed out his chest and raised his head: "Okay, okay, let's get engaged right away."

Since sixteen is the legal age for marriage, can they get engaged first?

It will be legal then.

Hermione rolled her eyes and scolded, "Silly girl. But you still need to sort out your identity issue, don't you?"

Yes, so far, apart from being a student at Hogwarts, Lin Yu seems to be an unregistered person in the world of ordinary people in Britain.

It seems we need to find a solution.

Lin Yu looked at the fish soup in the pot and muttered, "Leave the fish belly for later; I need to go pay a visit to Dumbledore."
