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

The sky gradually darkened.

In front of Hagrid's Hut, with Hogwarts Castle not far away on his back, Lin Yu practiced the Nine Forms of Cloud Abyss on his own, and then tried all the basic spells that first-year students could access.

It's obvious that he has great talent, after all, he now has a unique advantage, namely the Chaos Dao Body.

It can be said that the Daoist arts are naturally formed.

Isn't magic also law?

This allows Lin Yu to effortlessly wield all spells and magic.

Lin Yu even had a sudden inspiration. While using the Illumination Charm, which is essentially a flash of light, he pondered, "Since Transfiguration can turn firewood into needles, could we change light into a beam of sunlight? In that case, even a simple Illumination Charm could have the power of a laser ray."

Thinking it through, Lin Yu began to try it out.

If Professor McGonagall, or even Dumbledore, knew what Lin Yu was thinking, they would probably be quite surprised.

You're a real genius, damn it.

Unfortunately, Lin Yu had only recently come into contact with magic, and all he could do was turn a match into a needle.

Despite repeated attempts, he was unable to change the shape of the light from the Illumination Charm.

But Lin Yu believed that he would succeed sooner or later.

Since Snape could invent such a powerful attack spell as Divine Strike, he himself could certainly do it too.

However, it's not the right time yet; he needs to continue practicing magic.

As darkness fell completely, Lin Yu finally finished his solo practice and followed Hagrid into the cabin.

Ya Ya silently followed behind the two. Although Lin Yu was still worried that Ya Ya might suddenly open its bloody mouth and bite him in two, he was gradually getting used to Ya Ya.

"I've prepared some vegetables and roast meat for you. I hope you'll like them," Hagrid said considerately. He couldn't very well send Lin Yu back to the castle to enjoy a more delicious dinner.

In addition, as a gamekeeper and guard of the Forbidden Forest, Hagrid also planted many vegetables around his cabin.

For example, pumpkins.

Potatoes, in particular, are more than we can ever finish.

Lin Yu found it very strange that Europeans and Americans liked potatoes so much.

Whether as a side dish or a staple food, they seem to be inseparable from potatoes.

Lin Yu was so full he was about to throw up.

Baked potatoes, fried potatoes, mashed potatoes, potato soup, potato pancakes.

They've really come up with some amazing ways to eat potatoes.

Although some of them are indeed quite good.

Fortunately, there was still barbecue to eat, and it was no longer "rock skin" (a type of grilled meat), otherwise Lin Yu would have really cursed.

Thanks to Haig's warm hospitality, Lin Yu finally enjoyed a decent dinner, and the two had a pleasant conversation, which also improved his relationship with Ya Ya.

At least when the toothy creatures crawled at his feet, even resting their big heads on Lin Yu's feet, he no longer worried that his feet would be swallowed.

Actually, Ya Ya originally wanted to rest her head on Lin Yu's knees, but Lin Yu felt disgusted when he saw the drool dripping from Ya Ya.

The only downside is that Hagrid is actually a heavy drinker. He loves to drink, including when they first met and Hagrid accompanied Harry to Diagon Alley. Hagrid said he had something to do, but he took some time to go to a roadside pub for a drink before buying Harry Hedwig as a gift.

Good guy.

Unfortunately, Lin Yu was not yet seventeen years old, so he could only watch as Hagrid drank heartily.

Finally, before 8 p.m., Lin Yu said goodbye to Hagrid: "I should go back now. I'll come over again when I have time. By the way, we first-year students don't have classes on Friday afternoons, so maybe you could invite Harry over for a visit."

Lin Yu knew that Hagrid cared about Harry a lot, so he offered a good suggestion.

Hagrid escorted Lin Yu to the door, then asked again to confirm, "Are you sure you don't need me to take you back? Or should I have Tooth take you to the castle?"

Lin Yu politely declined: "Thank you, but Ya Ya, it's really alright. Maybe if I wait a few more years, I won't be afraid of him anymore."

With a sob, Ya Ya went inside sadly.

After bidding farewell to Hagrid, Lin Yu took out his wand and used the Illumination Charm to light the way under his feet, preparing to return to the castle with uneven steps.

But halfway there, he suddenly remembered that he had already mastered the Nine Styles of Cloud Abyss Sword Technique, and sword control was a piece of cake for him.

Why bother going back?

At that moment, Lin Yu took out the Cloud Mist Sword again and threw it at his feet.

As he lifted his feet and stepped onto it, with a thought, he channeled his spiritual energy into the sword, and the Cloud Mist Sword beneath his feet began to float and drift.

He actually flew?

Lin Yu's eyes lit up, but he soon felt that his spiritual energy was disappearing. He had no way to replenish his spiritual energy in this magical world.

Thinking of this, Lin Yu flicked his wand and chanted, "Yugadimur Leviosa."

It is the incantation for the Levitation Spell.

He used a levitation spell to lighten the weight of himself and his spirit sword, instantly making the consumption of spiritual energy negligible.

Then Lin Yu used his swordsmanship to fly towards the castle, and in the blink of an eye, he was back at the back gate of the castle.

The castle was about to close, and Lin Yu rushed in before it did.

Then Lin Yu jumped off the spirit sword, put it away, and returned to the Gryffindor rest area.

When he returned, he saw that Harry and Ron were still awake and playing chess in the common room.

"Lin Yu, where did you go this afternoon?" Ron asked curiously.

Lin Yu casually brushed it off, then noticed Harry looking at the chessboard with a headache. It turned out to be wizard chess. Although the rules were the same as chess in the human world, the wizard's pieces were not ordinary.

On the chessboard, Harry's pieces were chattering and shouting, as if they had their own ideas and were completely disobeying Harry's commands.

Even when Harry gives the command, some pieces will move in the opposite direction.

On the other hand, Ron's chess pieces, though old, were his own, and he said they were inherited from his grandfather.

But Ron's pieces were very obedient, and Ron was clearly a better player, so he quickly annihilated Harry.

Yes, literally, Ron's pieces will smash Harry's pieces to pieces one by one.

Although they will soon be perfectly reassembled.

Then, Harry's chess piece will complain to Harry: "Your chess skills are absolutely terrible."

Harry remained silent.

Lin Yu watched for a while, finding it interesting, and then prepared to go upstairs.

But then he noticed something: there was a notice posted in the rest area, specifically reminding the first-year students that they would have their flight lesson at 4 p.m. the next day, Tuesday.

First-year students are not allowed to bring their own magic brooms, because they haven't had any flying lessons yet.

This will be their first time learning how to fly using a magic broom.

Meanwhile, this flight lesson was being held together by first-year Gryffindor students and Slytherin students.

"The opportunity has come," Lin Yu thought to himself. He hadn't forgotten that he still had a mission to fight back against the Slytherin students of Canaan College.
