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

"Finally reached the fifth level of Qi Refining. However, it's a pity that if I had known that although this world has no spiritual energy, I could use the spirit stones given by the system to improve my cultivation, I shouldn't have let the system change the previous reward to improve my cultivation by one level of Qi Refining."

Lin Yu sighed silently.

The initial reward was clearly "current cultivation level one", not "directly increase cultivation level by one level in the Qi Refining stage".

Wouldn't you say he shot himself in the foot?

You dug your own grave, didn't you?

"And we've already used up a batch of spirit fruits," Lin Yu sighed. "I still need to feed the remaining ones to little cutie Hermione. I need to raise her favorability with her as soon as possible, before that kid Ron comes to his senses."

He doesn't like being a minotaur; he's a warrior of pure love.

"Speaking of which, besides the Marrow Cleansing Pill, I can now also refine the Grade One Rejuvenation Pill, as well as the Grade One Ghost Soul Pill, the Grade One Spirit Gathering Pill, and the Grade One Qi Gathering Pill."

Lin Yu began to ponder the elixir formula in his mind.

The Rejuvenation Pill is a medicine for treating internal injuries, while the Ghost Soul Pill is used to restore consciousness. Although the Spirit Gathering Pill and the Qi Gathering Pill differ by only one character, their effects are completely different.

The Spirit Gathering Pill contains spiritual energy, similar to the effect of a spirit stone, and can directly improve one's cultivation level; it is commonly known as taking a drug to become stronger.

The Qi Gathering Pill can help cultivators increase their absorption of spiritual energy during cultivation.

Unfortunately, this world lacks spiritual energy, so the Qi Gathering Pill seems useless?

In fact, the Marrow Cleansing Pill is also a first-grade pill formula, which is used by major sects to help their disciples cleanse their marrow and remove impurities. That thing is useless to those who have already become cultivators; at most, it can only improve their aptitude.

Taking advantage of the time he still had and the abundance of medicinal herbs in his system space, Lin Yu was planning to start refining pills in his alchemy furnace again.

But then he suddenly realized that he didn't have a stove on hand. Should he go find Snape?

Let's just forget about it. Although Snape doesn't seem to be targeting us as much anymore, it's best not to provoke him.

Helpless, Lin Yu had no choice but to temporarily abandon his idea of ​​refining pills.

Moreover, although the Spirit Gathering Pill can improve cultivation, as anyone who has read the novel knows, cultivation improved by taking pills will lead to an unstable foundation.

Lin Yu still wanted to take things one step at a time, solidify his foundation, and then gradually improve his level.

Because the Room of Requirement wasn't very big, Lin Yu originally wanted to practice his swordsmanship, but in the end he had to give up.

He didn't want to destroy this place, otherwise there would be nowhere to cultivate in the future.

Moreover, the Room of Requirement is a very important "scene"; we still need to find a Horcrux hidden here.

Lin Yu packed his things, and just then the Spirit Gathering Array's effect ended, although it wouldn't have mattered even if it were still there.

Lin Yu suddenly had a brilliant idea: "Although the Spirit Gathering Array cannot convert the magic power of this world into spiritual energy, can it highly condense the magic power? For example, when fighting an enemy, if I activate a Spirit Gathering Array, will the magic I release be more powerful?"

Although it's impossible to convert magic into spiritual energy, wouldn't it be a form of enhancement to greatly increase the magic around oneself through the effect of a spirit-gathering array?

"Furthermore, there's a formation that can actually convert spiritual energy, although it converts demonic energy, yin energy, and other energies from the mystical world into spiritual energy. But if I understood the principles of the formation and grasped the nature of demonic power, could I convert demonic power into spiritual energy?"

Lin Yu even started to let his imagination run wild.

Ultimately, magic and spiritual energy are both forms of energy. Magic can transform a wizard's thoughts into magic, or even create something from nothing, such as suddenly igniting a sea of ​​fire in the air.

This is simply creation-level energy.

Not to mention Transfiguration, many people may not have realized how powerful Transfiguration is.

That is something that can change a substance, or even a certain form.

Transfiguration can not only turn animals into cups, but also make inanimate objects move, or turn stones into gold.

Although the effects of the Transfiguration spell on gold can be dispelled, it can at least temporarily create a convincing illusion.

Furthermore, if the effects of the Polymorph spell are not undoed with magic, the spell's effects may even become permanent.

What is this? It's practically the Creator!

The magic in this world is bizarre. If you were to ask how powerful the magic in this world is, it actually isn't.

Even though dragons exist in the Harry Potter world, they don't have the earth-shattering magic of dragons found in some fantasy genres.

Dragons have even become magical creatures bred by humans.

Moreover, large-scale magic is very rare in this world, and the so-called three unforgivable curses are actually quite weak.

However, upon closer examination, much of the magic in this world is also very powerful, a kind of power in itself.

For example, Apparition and Apparition are techniques that any seventh-grade student can master; they involve large-scale teleportation and instantaneous movement.

There is also a lot of idealistic magic.

So Lin Yu wondered, in what form are the magic and magical power in this world supported?

What exactly is magic?

Is it really true that his Devouring Heaven Divine Skill cannot absorb demonic power?

So, is it possible to use formations to convert magic power into spiritual energy?

After leaving the Room of Requirement, Lin Yu had been thinking about this matter.

The three unforgivable curses, in particular, are proof of idealism. Without a strong enough emotion, an ignorant child's act of "biting a melon" cannot kill anyone.

Not to mention the Guardian Charm, the power of which has nothing to do with talent or so-called magic, but rather with belief.

That's magic that requires feelings of happiness and joy to use.

In other words, the happier and more joyful you are, the stronger your guardian spell becomes.

So what exactly is magic? And what are the principles behind magic in this world?

It's as if even the wizards of this world haven't fully figured it out?

Modern wizards simply hold a wand, learn spells and the fixed trajectories and postures for waving the wand step by step, and then naturally unleash magic.

Lin Yu sighed silently, "I always feel that the task ahead is arduous and far-reaching."

He discovered that there was still a lot he needed to learn.

Before we knew it, it was evening.

Lin Yu met Harry and Ron again at the dinner table, along with Hermione.

Lin Yu also noticed that Hermione was reading a book, and he asked, "What's this?"

Hermione, without looking up, said, "Quidditch origins. I found that this lists seven hundred legitimate fouls."

"Why are you watching this?" Before Lin Yu could speak, Ron asked curiously from the other side.

Hermione genuinely wasn't interested in magic brooms; in fact, she didn't really have any talent for them.

Even yesterday, during the second flying lesson on Thursday afternoon, Hermione still couldn't get her broom into her hand in one go.

Hermione looked up and glared at Ron, then glanced at Lin Yu, snorted, and continued to bury herself in her book while eating dinner.

Lin Yu smiled and placed a spirit fruit in front of Hermione.

Although he ate a lot to improve his cultivation, he still kept some, which was specifically for feeding.

Hermione quickly grabbed the spirit fruit and stuffed it into her pocket, a slight smile playing on her lips. It was worth the effort of finding this book.
