Since Hogsmeade Village, Zhang Jin has returned to Hogwarts.

In the past few days, Zhang Jin has been staying in the responsive house and has not come out, and even the house-elves in the school kitchen are solely responsible for eating.

Originally, Zhang Jin just gave it a try, but he didn't expect the house-elves to be able to enter the Room of Requirement, and it is estimated that they are far more familiar with Hogwarts than the average faculty and staff, but they don't know how to compare to Dumbledore.

Of course, Zhang Jin was not idle.

The potions that had not had time to be studied properly for one reason or another finally began to try to understand them.

In the past few days, he has made some simple potions from the textbook, and then re-formulated them according to Severus's improved method.

Zhang Jin hopes to discover some of the principles in the potion preparation process.

In the wizarding world, spells already have some simple systems, such as spells, how they are cast, and most importantly, how they are cast.

So there are a lot of spells invented by students at Hogwarts, although most of them are minor charms or mischievous spells.

The most famous is Severus's invention of the Upside-Down Golden Bell Pole Curse, which spread throughout the school in a very short period of time and became one of the most popular spells.

Another well-known spell is Severus' invention of the Blade, which is a high-level attack spell that inflicts the effect of a sword on the medium.

Therefore, it is not difficult to invent spells, and even high-level new spells can appear in a few years.

Even in the upper grades, some small or simple spells can be cast silently, and even excellent students can do a certain degree of wandless casting.

(One of the waiters at the Leaky Cauldron Bar is skilled at using a wandless spell to set up chairs, and judging by his age, he must have just graduated.) ）

But it has always been difficult to invent potions, and even a potions genius like Severus can only improve the way potions are prepared.

If all the spells in the wizarding world are counted, there should be hundreds of thousands, but there are only a hundred and ten kinds of potions, most of which are poisons and their antidotes.

Potions has always been one of the hardest magic classes at Hogwarts.

Of all the basic courses, only Potions has no theoretical basis.

The few laws that are named are just summaries of experience, and they are not necessarily right or wrong.

For example, Gobarott's third law, which appears only in the original book: the ingredients of the antidote to mixed poisons must be greater than or equal to the sum of the components of the antidote to their individual poisons.

The reason is that when potions of different ingredients are mixed with each other, additives need to be added between different materials to make the materials better combined.

So the more ingredients you mix, the more additives you need and the more potion materials you use.

However, this law was soon broken. After Weasley accidentally drank poisoned alcohol, he was unable to prepare a targeted antidote due to time constraints.

Then Harry Potter solved the problem with a dung stone, and all the laws and principles were gone.

This is a bit like the development process of traditional Chinese medicine, when there are too many herbs, some ingredients need to be added to neutralize the side effects of some herbs.

However, it was later discovered that some herbs can also neutralize side effects with each other, so the amount of dosage is still inconclusive.

Potion making in the wizarding world has always been an accumulation of experience, just like alchemy as we know it now.

Wizards, including Potions Masters, only know which potion materials can be fused together in some special way to form potions with certain effects, but no one knows why.

In this regard, the development of potions is not as good as that of ancient Chinese medicine, which had already had medicinal properties, dosage, heat or citation methods before the Tang Dynasty.

Potions, on the other hand, are still focused on exploring the formula of the material, and the study of the properties of the material has been stagnant.

Not to mention the formation of a scientific system like chemistry.

This is unbearable in the eyes of Zhang Jin, who studied chemistry in his previous life and has undergone a scientific system education.

And Zhang Jin's biggest dream when he came to the wizarding world was to be able to discover the essence of magic, and it was best to establish a set of magic theories.

Potions are the best subjects to study.

The magic of potions is incredible even to many wizards.

The most typical is that only wizards with magical powers can concoct potions, while Muggles and Squibs without magical powers cannot concoct even the simplest potions for scabies.

This is the most basic principle of the wizarding world: only magic can create magic.

But no one knew what magic was.

For example, people who don't have magic can't make potions, why on earth?

You know, many simple potions just process the potion materials step by step during the preparation process, and add them in order.

So what happened in the process?

Zhang Jin devised a few simple experiments:

Test 1: Isolate one's own magic during the entire operation, and wear gloves that block magic to operate.

Experiment 2: Wear gloves that isolate magic when handling potion materials, and boil and remove gloves to operate normally.

Test 3: Handle potion materials as normal, and wear gloves to isolate mana when boiling.

The results were still very good, and although the potions were successfully formulated in all three experiments, the potions produced in Experiment 1 were obviously of inferior quality.

This shows that as long as the wizard has magical power, they will have mana overflow when they are unconscious, and these overflowing magic power is enough to make those simple potions.

At the same time, it also shows that the process of preparing potions does require the magic guidance of a wizard.

How did that lead?

At this time, Zhang Jin conducted a series of experiments:

First, when preparing the scabies treatment potion, I imagined that I was preparing a blessing elixir, and the efficacy of the results was reduced.

Then there was a strong desire to succeed in the preparation of the scabies treatment potion, and then it failed.

Finally, there was a strong desire for success and an increase in the efficacy of the drug in the preparation process, and the result was a better potion as expected.

Therefore, whether or not a potion can be successfully prepared depends mainly on the wizard in addition to the materials and operations.

So is there a difference between a wizard with strong magic and a wizard with weak magic making potions?

There must be something, just like at the beginning, even if Zhang Jin isolated the magic power of the whole body, he could still prepare a simple scabies treatment potion using the gloves that isolated the magic power.

But if you change to a first-year little wizard, it is estimated that it will not be possible.

Similarly, the more complex the potion is, the more powerful it is, and the stronger and more complex the magic channeling.

This also explains why the preparation of high-grade potions is very complicated, probably for more detailed mana channeling.

The more delicate the operation, the deeper the will involved, and the more magic is infused to bring out the properties required by the potion.

The wizard's own magic is guided by the will and fuses with the magic of the potion material itself, which becomes a potion.

So, the potion actually embodies the will of the wizard.

It's magical, like a spell, and while it can be done with a step-by-step dogmatic practice, it's undoubtedly more important to know exactly what you want.

Just like Hermione. Granger and Luna. Lovegood is the same as both.

Hermione's dogmatic learning was sometimes not even as effective as Luna's whims.

So Hermione could only learn the spells from the textbooks, while Luna was able to develop some new spells.
