Hogwarts starts with stealing power.

The same way Lin Xia arrived in the morning was how she left the Ministry of Magic in the afternoon.

After reaching the ground, she hailed a taxi and quickly arrived at London Station.

When she crashed into the wall through the hidden passage, the Hogwarts Express was already waiting there.

Lin Xia entered the station and brought another gift for the train conductor.

She was taking a taxi when she passed a shop selling local specialties, so she asked the driver to stop, went inside, and bought some food that Muggles like to eat.

This gift isn't expensive; consider it just a small token of my appreciation.

The train conductor seemed to be in a good mood. After receiving the gift, he smiled and said, "Little wizard, don't be so polite. Hogwarts always gives me a stipend for each trip."

Lin Xia smiled slightly: "Uncle, just think of it as me giving gifts to others."

The train conductor laughed heartily, accepting the little wizard's "concern," and remarked, "These days, it's rare to see a little wizard as enthusiastic and generous as you."

He seemed to remember something and deliberately said, "Do you know that there is a separate compartment in the train that was created using spatial magic?"

Lin Xia raised an eyebrow. A private cubicle?
She shook her head: "I'm not sure."

The train conductor said, "This compartment has a large capacity, and only the student council president and some prefects know about it. It was originally designed for nobles who ride the train."

I immediately thought this design was completely unnecessary; why would nobles ride a magic train?

The train conductor shrugged. "But since the nobles funded the investment, we had no choice but to design a hidden compartment according to their requirements."

The facilities inside are very complete. You can go and take a look at that compartment, which is located at the entrance of carriage 10, at 3 3/4.

Lin Xia's eyes flickered slightly. She thanked the train conductor for the suggestion and said with interest, "I'll go check it out now."

Upon arriving at the 10th carriage, she did not find the so-called 3 3/4 entrance, but after a careful search, she found the mark in a scratch on one of the carriages.

It was a very small mark, engraved on the edge of a relatively tall suitcase cabinet.

However, given Lin Xia's height, she didn't need to stand on tiptoe; she could easily touch the mark simply by reaching out her hand.

After the gentle touch, she suddenly heard a soft clicking sound in her ear, and a subtle fluctuation of magic energy emanated from behind her.

Lin Xia turned her head and saw a light blue magic door in front of her.

She was certain that only by touching these words could she see the magic door.

Lin Xia circled the frame of the magic gate with interest, sensing the magical fluctuations in the air and analyzing them in her mind.

"The use of spatial transfer doors is very ingenious, the arrangement is also clever, and the activation method is simple and quick, but it is just too simple."

But Lin Xia thought that this method was worth learning, such as building a fast passage from the dormitory to the laboratory.

Suddenly, something occurred to her, "I wonder if it's possible to bypass the magic gate's verification by using a high-dimensional spatial teleportation magic like the Otherworld?"

Lin Xia decided to give it a try.

She first passed through the magic door, and only after entering did she discover that the interior space was even larger than the train conductor had described, almost a hundred square meters.

The space is divided into several areas, including a reception area, a laboratory area, a dining area, a sleeping area, etc.

Because it is divided into several areas, each space does not look very big, but the overall space area is not bad. It is a case of "small but complete".

As a super-express train that can reach its destination in a day, the creation of such a house is clearly a luxury.

However, considering the aristocratic lifestyle, Lin Xia felt it was quite normal.

She closed her eyes, created an anchor point in her mind to determine the location, and then found the inscription using the appropriate method. Gently touching it, a semi-transparent magic door appeared in front of her.

Lin Xia walked out and returned to the original place.

She closed her eyes again, set an anchor point, and using the spatial transfer methods she could understand, quickly found the fold line where the two spaces overlapped on the plane.

Anchor point established, zigzag line established... She mobilized the magic power within her body and began the spatial transfer to the inner world.

With just a light step forward, Lin Xia opened her eyes again and found herself inside the hidden space.

Lin Xia smiled slightly. Not bad. It seems that the method of transferring within the inner space is not afraid of any surface defense and can establish a link anytime, anywhere.

Unfortunately, she hasn't broken through Hogwarts' defenses yet; there are still some key points she hasn't figured out.

If she is familiar with the defense system, she can leave Hogwarts directly from the school using the method of teleportation within the inner world.

In the comfortable and secluded space, Lin Xia took out the blueprints for the alchemical glasses.

Time is of the essence; every minute and second must be used to conduct the research.

Once she arrived at the school, her schedule was very tight, and she might not be able to find much time to study the blueprints.

Upon opening the blueprints, Lin Xia was astonished by the densely packed structures inside.

Alchemy glasses are indeed one of the pinnacle achievements of modern alchemy.

Who would have thought that a pair of small glasses contained hundreds of miniature magic runes!

All the magic runes are embedded in the hollow interior of the glasses, and both the outer and inner layers are protected by special metal!

Even though Lin Xia's research on magic runes has reached an advanced level, she would still be a little overwhelmed if she were to look at hundreds of miniature magic runes at once.

She was only in a daze for a moment, and soon she focused her gaze on the first miniature magic rune array.

The diagram of the alchemical glasses is clear and simple, and the magic runes shown at the beginning are arranged from simple to complex.

However, this is only a ranking of difficulty based on the magic runes; it does not mean that the entire frame of the alchemical glasses is ranked from simple to difficult.

Turning to the structural diagram at the back will show in detail what the magic runes of this component are like, and what the magic runes of another component are like.

Lin Xia casually flipped through the back and made a surprising discovery.

"The magic runes on these alchemical glasses are constructed according to an orderly arrangement of three levels: easy, easy, and difficult, forming a magic rune array of a relatively large difficulty level."

Soon, Lin Xia understood the significance of this arrangement.

She pushed her wand to create one of the "easy-easy-difficult" rune combinations directly in the air, and found that this made the magic transmission more efficient.

"Moreover, the construction circuit of this magic rune array forms a unique rhythm when placed inside the glasses, making it even more efficient than a combination of multiple difficult magic rune arrays stacked together!"

A glint of light flashed in Lin Xia's eyes. Judging from the group of alchemy masters she had met this afternoon, this kind of efficient permutation and combination was probably not what they had in mind.

Perhaps this is the work of the master Nicolas Flamel?
Judging solely from the arrangement and combination of runes, he knew that Master Nico's skill in runes far surpassed hers; at the very least, she couldn't conceive of such an energy circuit. In contrast, her understanding of runes was limited to knowing the function and structure of each rune, but she couldn't create more in-depth arrangements and combinations.

Even if they tried to create it, they could only get stuck in simple magic runes.

After all, even a simple magic rune array can become difficult when it is superimposed with three or more layers.

Thinking of Master Nico, Lin Xia felt relieved.

"Indeed, some knowledge can only be accumulated with the gift of time."

Lin Xia first looked through all the magic runes from simple to difficult, making sure she understood them all. Then she turned to the next page and started looking directly at the composite magic rune on the frame.

Don't underestimate the alchemical glasses just because they're a small item. The alchemist not only inscribed relevant magical runes on the frame, but also embedded many miniature magical runes in the huge mirror surface, which played a crucial role.

It allows wizards' mental powers to connect with each other.

The handle of the mirror frame can directly contact the wizard's skin, serving primarily as a detection and access point.

The magic runes on the mirror are very complex, and can construct a complete virtual model in the wizard's mind, transforming the real world into an illusion.

Time flew by, and Lin Xia was awakened by the whistle of the express train when she came to her senses.

She quickly emerged from the secluded space and, looking through the window, realized she had arrived at the station.

The train conductor's voice rang out throughout the carriages: "The school has sent another professor to pick you up and take you to Hogwarts."

Lin Xia had already seen the professor approaching through the window, and a smile appeared on her lips.

Hagrid also saw Lin Xia, shouted at her, and waved.

"Lin Xia, come down quickly, it's getting dark, and we don't have much time left!"

The sky was already getting dark, and Hagrid held a huge lantern in his left hand, inside which was a radiant candle.

The warmth emanating from the candles shielded Hagrid from the influence of the evil god's ravings, making him seem to glow in the slightly dim environment.

This is one of the characteristics of glow candles, but this property is not obvious in small candles that are usually sold.

However, the Radiant Candles that the school provided for Hagrid were at least three times larger than those sold to the public, so their special properties were very obvious.

Lin Xia walked over quickly and asked curiously, "Why are you here to greet me, Hagrid? Actually, I can go back by myself. This level of darkness doesn't affect me."

Hagrid smiled and said, "I heard that your lab is about to produce new results, which will be published in the journal 'Potions.' In the school's eyes, you are more important than many professors."

Lin Xia shook her head. "That's not my achievement. It's the Weasley twins' work. Their inspirational potion is very interesting and can benefit many wizards."

Hai Ge: "But it was launched under the name of your lab, wasn't it?"

Whether they developed it themselves or someone else did, as long as it's released under the lab's name, they'll all attribute it to you, Lin Xia.

Lin Xia said helplessly, "There is still a difference. I am me, and the lab is the lab. I don't want to take credit for the work of real researchers!"

The return journey went smoothly, and they arrived at the gates of Hogwarts as dusk fell, successfully entering the campus.

Lin Xia wore a specially made black pill and arrived at the auditorium without attracting anyone's attention.

The black pills played a significant role during this trip, as even the wizards at the Ministry of Magic failed to notice anything unusual about her aura.

But it's also possible that she didn't see many high-ranking wizards at the Ministry of Magic.

The alchemists may be highly skilled in alchemy, but they are not very good at magic cultivation; they are all intermediate wizards.

Only the older man reached the advanced level, but he didn't notice anything unusual about Lin Xia.

In the Great Hall, the news that the Weasley twins would be publishing a paper in the journal Potions next week was already spreading like wildfire.

Lin Xia saw a large group of wizards circling around the Weasley twins, asking them what research insights they had gained.

She sat down next to Draco, who saw her and whispered:
"The Weasley twins are truly worthy of being Gryffindor students. In just a few days, they made their 'great achievements' known to all the students in the school, and they became the talk of the town."

Draco's tone sounded somewhat complicated: "It felt even more enthusiastic than when you published your paper on the new wand in your first year and then gave a presentation on it in your first year."

Lin Xia countered, "Do you like the feeling of being the center of attention?"

He choked up and couldn't speak.

Lin Xia said, "The admiration of others can bring a sense of satisfaction, but it can also amplify a person's behavior infinitely. The Weasley twins are not eugenics in the conventional sense, so the young wizards are more curious about their discussions."

This is both an incentive and a spur.

Everyone has a different personality, and their reactions to external attention are also different.

The twin seniors were able to handle the pressure, but such admiration might not be a good thing for other wizards.

Even Harry took a long time to adjust his mindset.

Draco suddenly felt that it wasn't good that everyone was talking about it; he felt like a monkey being watched in a zoo.

After having lunch in the auditorium, Lin Xia went to the laboratory.

In the laboratory, Harry, Ron, and Neville were already seated in the common room area, each holding a thick stack of documents.

Compared to Harry and Ron's ease, Neville seemed somewhat anxious, with dark circles under his eyes, looking like a national treasure panda.

Lin Xia asked curiously, "Nawei, have you been sleeping poorly these past few days? It's so obvious. Do you want to go and rest for a bit?"

She was a little afraid that Neville would collapse at any moment.

After a long pause, Neville replied, "No, I can handle it. I've memorized all the information."

Ron immediately said, "Neville is much more diligent than us in this respect. It's incredible. I never expected him to be so hardworking!"

Harry also said, "I think this time we can give Neville more work, maybe motivate him, and he really can do it."

Upon hearing this, Neville became even more anxious, looking sadly at Ron and Harry, then staring intently at the documents in his hands.

He knew that his friends were giving him a chance, wanting him to overcome his anxiety and the inferiority complex hidden in his personality.

Neville also wanted to stand in the front row, head held high, as an assistant and commentator.

He initially felt he was completely incapable of the task, but in the last few days he's started to think that perhaps he really could. (End of Chapter)
