Sky and mountains, and land and water, all greyish-white.

Chen Yu wasn't reminiscing about a middle school text, reciting something like "Watching Snow from the Lake-Heart Pavilion."

Instead, this was the current scenery inside the Serenitea Pot.

The sky was greyish-white, the ground was greyish-white, and even the plants remained greyish-white.

The entire interior of the Serenitea Pot looked like a faded, greyish-white photograph, and everything was in a static state.

The only thing that wasn't grey was probably the large orb in front of him.

Unlike the moon, which was also an illusion, as the sun illuminating the entire Serenitea Pot, it was both a physical object and the core hub controlling the entire Serenitea Pot.

The Serenitea Pot wasn't activated yet, and the entire space consisted of only one island.

Unlike the world of "Genshin Impact" which has several islands suspended in the air.

Currently, there was only one floating island within the Serenitea Pot.

Chen Yu felt like he had acquired a simplified version of the Serenitea Pot.

Apart from this one island, the vast expanse of heaven and earth revealed nothing else.

Following the instructions given by the system, Chen Yu used a Cutting Curse to break the surface of his finger and dripped a drop of blood onto the orb.

Chen Yu felt like complaining a bit.

He wondered when this method of blood-binding to acknowledge a master became the mainstream way for Eastern magical artifacts to recognize their owner.

When Chen Yu dripped his blood onto the orb, the entire space instantly burst into color.

It switched directly from greyish-white mode to ultra-clear mode.

Chen Yu officially gained control of the Serenitea Pot.

Now, Chen Yu could freely adjust the rotation of the sun and moon and the changes of the stars within the Serenitea Pot.

It sounded impressive, but in reality, aside from controlling the movement of Luofu Island and the core hub, all other scenery was an illusion automatically generated by the Serenitea Pot system.

Furthermore, within the Serenitea Pot, Chen Yu could fly using only Telekinesis without consuming magic.

He could also uproot the few trees on Luofu Island and change their positions using only Telekinesis.

He could even switch to greyish-white mode and shout "Za Warudo" inside the Serenitea Pot to stop time within it.

The area of Luofu Island was not small; it felt like it could accommodate the entire Hogwarts Castle, with a small open space remaining.

However, the Serenitea Pot's space had its limits.

The vertical space was like a Mobius strip; jumping down from Luofu Island would result in falling back to the center of Luofu Island from the sky.

Advancing in the east, west, south, or north directions, exceeding one kilometer from Luofu Island, would be blocked by an invisible air wall.

Chen Yu looked at the barren island, his inner spirit for infrastructure and farming burning.

It would be a pity not to use such a good plot of land to build houses or farm.

Unfortunately, his Serenitea Pot had no pot spirit; let alone exchanging for experience books from its treasure trove, even if it could only help manage the Serenitea Pot, it would be good.

Chen Yu looked at the empty Serenitea Pot and began to consider his next steps.

It seemed he would have to go to the Library again to find weather spells, and also study the Undetectable Extension Charm notes Malfoy gave him.

He remembered in "Fantastic Beasts and Where to Find Them," the inside of Newt's suitcase was expanded using an Extension Charm, and different weather spells were used in different areas to simulate the habitats of various creatures.

Compared to Newt's suitcase, in terms of spatial size, his Serenitea Pot felt somewhat inferior.

If only he had known, he would have included weather spells when he extorted Malfoy; then he wouldn't have to search the Library.

After Christmas, Chen Yu went to Professor McGonagall's office.

To Chen Yu's surprise, Professor McGonagall calling him to her office alone wasn't to criticize him.

Instead, she warned Chen Yu again not to use Transfiguration to conjure dangerous Muggle items in front of other Little Wizards at Hogwarts.

This was to prevent reckless Little Wizards from learning it and causing unnecessary harm.

Of course, Professor McGonagall still admired Chen Yu, believing he had great talent in Transfiguration.

At least in the entire first year, only Hermione could barely keep up with Chen Yu's learning progress in Transfiguration.

Chen Yu also took the opportunity to ask Professor McGonagall about the difficulties he encountered while practicing Transfiguration Charms, listening to Professor McGonagall's detailed explanation of Transfiguration Charms, and also improving his skill proficiency... By November, the weather had become unusually cold.

Originally, after acquiring the Serenitea Pot, Chen Yu had some restless ideas.

He wanted to steal trees from the outskirts of the Forbidden Forest; after all, the Forbidden Forest had many trees, and taking a few to decorate the Serenitea Pot probably wouldn't be noticed.

He also wanted to go deep into the Forbidden Forest, bypass the Centaurs' blockade, and catch some fantastic beasts to put into the Serenitea Pot to add some vitality to it.

However, as soon as he stepped out of Hogwarts, the biting cold wind slapped his face like a big ear.

He hadn't gone far before Chen Yu decisively gave up the idea of digging up trees at that time.

Hogwarts Castle was still warm, with torches and fireplaces for illumination everywhere.

Spring drowsiness, summer heat, autumn fatigue, winter cold.

Recently, it was indeed not a good time to go out for inspiration; it was better to practice spells in the Room of Requirement.

Since the three little companions teamed up to defeat the Troll, the relationship between Hermione, Ron, and Harry had improved significantly.

With Hermione's addition, Harry and Ron undoubtedly had a new savior for their homework.

Originally, Harry and Ron's homework was copied from Chen Yu.

But Chen Yu, in order to make progress and go out for night strolls, wrote his characters incredibly fast.

This also resulted in Chen Yu's homework being written in a wild, flowing hand; except for Chen Yu himself, even the professors had to grit their teeth and stare for a long time to figure out what Chen Yu had actually written.

Fortunately, the professors at Hogwarts didn't send back homework for rewriting due to messy handwriting.

It was just tough for Harry and Ron, who always copied mistakes when doing their homework.

Now with Hermione, Harry and Ron immediately became fickle, saying Hermione's handwriting was beautiful and complaining that Chen Yu's handwriting looked like ants crawling.

Of course, as a good student, Hermione would not lend her homework directly to Harry and Ron for copying.

But under the guise of borrowing her homework to check for errors in their own, they could always get the correct answers.

Chen Yu had been somewhat envious of Harry's perseverance recently.

He could tell that Harry truly loved Quidditch.

Despite the cold weather, he still trained secretly with Wood every night, come rain or shine.

To help Harry understand Quidditch better, Hermione even specially borrowed "quidditch through the ages" from the Library for Harry to read.

Harry immediately fell in love with the book after a few glances, discovering for the first time that reading could be so interesting.

"quidditch through the ages" not only recorded the origin of Quidditch but also listed over seven hundred types of fouls during Quidditch matches, which strongly caught Harry's attention.

Chen Yu also discovered an interesting spell in "quidditch through the ages"—the Arrow-Shooting Charm.

This was a spell that could summon an arrow from the tip of a wand and release it quickly.

The book recorded that fans of the "Appleby Arrows" team often used this spell during Quidditch matches to show support for their team.

However, in 1894, an arrow pierced the nose of referee Nugent Potts, so the Department of Magical Games and Sports outlawed this old practice.

He still had too few spells in his repertoire.

If he had learned the Arrow-Shooting Charm before, he wouldn't have needed to use Transfiguration to turn fragments of a wooden stick into a gun.

He could have easily dealt with the two Trolls by hiding in the dark and using the Arrow-Shooting Charm for a sneak attack.

Although its power was a bit less than a pistol, the advantage was that the sound of its release was very small.

Aside from the whooshing sound of the arrow cutting through the air, there was almost no other noise.

Tonight, Harry was still in secret training.

Currently, only Neville, Seamus, Ron, and Chen Yu were in the dormitory.

"Are we still going out to practice spells tonight?"

Chen Yu's roommates were already used to him going out for night strolls every evening.

Chen Yu changed into his fleece-lined wizard's robe and replied to Ron, "Of course."

Chen Yu's roommates weren't at all envious of how quickly his spellcasting improved, because they all knew that Chen Yu practiced spells in a secret base every night until very late before returning.

They heard that Hermione from the girls' dormitory was almost the same as Chen Yu, except she read books in the dormitory until very late, while Chen Yu practiced spells until very late.

"By the way, the Quidditch match. Ron, Seamus, Neville, are any of you interested in making a little money at the game?"

Chen Yu stopped and asked with interest.

Neville Longbottom's family was not short on money, so he wasn't very interested in making a little extra cash.

Although Seamus was a half-blood wizard, his family's financial situation was much better than the hand-to-mouth Weasley family.

So, the only one interested in Chen Yu's method of making a little money was still Ron.

"Making a little money? How? It wouldn't be like Fred and George setting up a betting pool, would it? If so, we're already a step too late, because Fred started selling betting slips a week ago, and everyone who placed a bet voluntarily cast a secrecy spell to prevent the professors from finding out. If we do the same, we're already too far behind them."

Chen Yu shook his head and said, "No, no, no, we'll do something legitimate. I had Dora order a batch of snacks when she went to Hogsmeade, and I'm planning to sell them at the Quidditch match. You can ask Fred and George if they're interested. If they are, we can meet in the Hogwarts kitchens two hours before the Quidditch match."

With that, Chen Yu walked towards the common room.

After he walked out of the dormitory, Chen Yu suddenly poked his head back in.

"Tell me, what are the odds for Gryffindor to win?"
