In fact, the Weasley twins don't know much about alchemy, but they have a lot of experience in practical operations, and there is no doubt that the two are self-taught, and many of their steps conflict with alchemy books, but following the Weasley twins' steps will only be easier, and the success rate will be greatly increased.

In this way, for three days in a row, every day at lunch, Li Lin sat at the Gryffindor table, listening to the experience of the Weasley twins.

In this way, Li Lin's understanding of alchemy has deepened a lot, and he can even make some mischief toys.

"Thank you very much. Thank you for your help. ”

Li Lin said to the Weasley twins, and the two brothers kept talking.

"Oh no, dear friend."

"Your talent is so outstanding."

"Stay, you deserve to be a Gryffindor. Open a joke shop with us. ”

"Our products will be exported to the Americas."

As soon as Fred and George finished singing and harmonizing, they began to applaud, Li Lin smiled and shook his head, they are such characters.

"Well, I'm going to say I'm sorry."

Li Lin waved his hand.

"I am the eagle of Ravenclaw, an eagle whose eyes are like torches, and who pierces the darkness."

He said this, declining the Weasley twins' invitation.

Fred and George looked at each other and joked with each other.

"That's a shame."

"The Great Auror of the Future."

"Your loyal Weasley salutes you."

"St. Ann, St. Lovegood."

Li Lin said goodbye to the exaggerated Weasley twins and returned to the Ravenclaw table.

"Huh? How's it going? ”

Hermione asked, eating her snack.

"I don't think there's a problem in passing the exam."

Li Lin picked up a small piece of cake in his hand. Of course, it's not because he likes sweets, he just thinks the cream tastes good. Well, that's it.

"Lin, there are no classes in the afternoon, why don't we go and practice again?"

Hearing that Li Lin had improved, Hermione's confidence in alchemy had returned a little, and she couldn't wait to see the magic of alchemy.

Li Lin finished the cake in his hand and licked the cream on his fingers.

"I think it's fine, of course, you need to bring some materials."

Although there is a room for requirement, you can conjure up almost everything you want. But Transfiguration is also in accordance with the Basic Law.

In the past, there were some wizards who came up with things like the so-called basic laws of Transfiguration, but with the development of magic, these laws gradually became loopholes, and eventually they were considered wrong. But until now, there are still iron rules that have not yet been broken.

For example, deformation food, Transfiguration can do it, turning stones and dirt into cakes, roasting chicken, but the problem is that eating these things has no effect on the human body at all. They're essentially non-nutritious.

But if you turn the pancake into a cake, you can make it full.

Another example is the transformation of magic items, so far, no wizard has been able to transform an ordinary branch into a wand, which refers to the wand that is really useful, and no wizard can turn a stone into a broomstick.

There are also some so-called rules, but there are people who have broken them throughout history. So I won't talk about them all.

Therefore, even if Li Lin fantasized about a room full of wands in the Room of Requirement, it would only be empty when he opened the door, because the Room of Requirement could not transform the wand out.

In the same way, the materials needed for alchemy cannot be provided by the Room of Requirement. Although alchemy is effective on ordinary items, there are also some things that contain magical powers.

So, Li Lin and Hermione, with some magic materials, came to the Room of Requirement.

The next thing is practice, I have to say, the experience of the Weasley twins is very effective, Li Lin, who was originally at a loss for alchemy, is now making alchemy items, but suddenly like a divine help, and quickly completed the first alchemy item on the "Primary Application of Modern Alchemy".

A teapot that automatically boils water and pours tea.

This teapot is not complicated to make, the raw materials just need a teapot, a small piece of molten stone that can heat the molten stone, and the dust from the wings of the flower fairy.

The dust on the wings of the flower elf has a revitalizing effect, and the specific manifestation is to make a normal object have spirituality, as if it suddenly came to life. The difficulty is that merging the lava stone and the teapot together is not something that can be done simply by using Transfiguration, in fact, if you need to use Transfiguration, Li Lin will be blind.

Through the experience of the Weasley twins, this is not to say that the Weasley twins also made this kind of teapot, but the Weasley twins, the way they thought when they made prank toys, which inspired Li Lin, who did not use the conventional method, that is, merging the lava stone with the bottom end of the teapot, which was very difficult, and lava stone, as a magical mineral, was also difficult to cast spells.

Li Lin chose to grind the lava stone into powder and mix it with water, which formed a lava stone solution, and then Li Lin used this lava stone solution to depict the bottom of the teapot as if it were dipped in ink. Because his art skills were not very good, Li Lin simply depicted the words in the magic text that represented the flames.

Next,It's the use of the dust on the wings of the flower elf.,This,There's a related operation technique.,After the teapot painting is completed.,Engrave the spell of constraints.,So the teapot that can automatically boil water and pour tea is completed.。

Of course, this kind of item can also be done with magic spells, and even if you hold a wand, it is easier to make alchemy items of this level, which is also the reason why alchemy is gradually declining, but the ultimate of alchemy, the existence of the Philosopher's Stone, is the most powerful pillar of alchemy. It is also the main reason why alchemy can still be active in the upper echelons of the wizarding world.

After seeing Li Lin's success in making alchemy items, Hermione's confidence was even more sufficient, and she had now completely blamed the reason for the failure of the previous exercises on the alchemy textbook. In her opinion, the book "Elementary Application of Modern Alchemy" is a perfect interpretation of the lack of rigor.

So, next, Hermione tried to make this teapot matching items from Li Lin's point of view, a tea table that can automatically fold and shrink, and a teacup that will automatically find the owner, and when there is no tea, it will take the initiative to fly to the teapot to refill the water.

Hermione lived up to her status as a top student, and then she didn't use a wand or chant a spell, and she succeeded in making it, and the tea table was already four teacups.

Hermione happily wanted to celebrate, but unfortunately, they didn't carry the tea leaves, so Hermione used her wand to fill the teapot with water, and then used Transfiguration to turn the pot into milk.

Li Lin looked at the advanced use of this Transfiguration Technique, he was simply a little dumbfounded, yes, the Transfiguration Technique, it can't turn stones into food, but it can turn clear water into milk, of course, this is just clear water with a milk flavor.

However, in magic, there is a spell like a spring of clear water, and water can be created out of thin air. What does this mean?

At this time, what suddenly came to his mind? He wondered if Jesus, who had divided the bread, was a sorcerer who used to make copies in pairs.

Thinking that the wizards still had Christmas, and Merlin, the most powerful wizard in the history of magic, did not rule the world, Li Lin felt that the water in it was really deep.

The world of Harry Potter is far from being as simple as it seems, and the water in it is likely to be bottomless.

Feeling that he might be challenging the super difficulty, Li Lin had no choice but to lament in his heart, but after taking a sip of the milk in the teacup, he frowned slightly.

He looked up, and Hermione looked bitter as well.

"It's not sweet." Hermione said.

"I tried adding sugar to it, but it doesn't seem like I succeeded."

"Okay." Li Lin stood up.

"I'll go to the kitchen and get some sugar cubes."

The next thing was logical, first the sugar cubes, then the cakes, and then, all kinds of sumptuous food, Li Lin and Hermione simply had another banquet in the Room of Requirement, after all, the house-elves have always been so enthusiastic, they were supposed to drink saliva, and it could serve you a big pot of soup. If you want to eat a piece of snack, they will make you a large piece of cake.

So wait until the evening when you return to the lounge. Li Lin and Hermione have already made their bellies round.

"Listening to Li Lin, I swear that I will never eat so much in the future."

The other students are now in the school cafeteria, but for Li Lin and Hermione, there is really no need to eat dinner.

Li Lin smiled bitterly and nodded.

I have to say that although the dishes made by the house elves are very monotonous, the taste of the dim sum and cake is really unique.

"Hermione, since there is no problem with my alchemy, there is no need to continue tonight's review."

After recalling his review progress, Li Lin said to Hermione.

In fact, Hermione's review had already been done twice, yes, she had already done it twice. Recently, I have been busy with Li Lin's "new course".

Hermione thought for a moment, then nodded.

"You're right, you've managed to overcome a difficult problem. So let's rest today. ”

Hermione stood up and winked playfully. In fact, she was also a little tired, after all, she was overly excited today, and she made several alchemy items in a row, which was very energy-consuming.

However, she also continued to admonish.

"But, Lin, we have to get up early tomorrow, let's review the history of magic again, I heard from the senior sister that there will be essay questions in the history of magic exam."

That was the third review, Li Lin sighed in his heart. Moreover, the essay question is the legendary additional question, which is attached to the following questions after all the questions are out in the entire exam paper.

It belongs to the extra question of answering incorrectly, no points will be deducted, and if you answer correctly, there will be extra points. Of course, for Hermione, all the questions were to be answered.

In fact, after nearly a year of getting along, Li Lin has learned more and more about Hermione, she is a lovely girl with strong self-esteem and kindness.

The reason why she worked so hard in school was because she really loved knowledge and longed for the magic of magic. On the other hand, it is to prove that children from Muggle families are no worse than other wizards.

That is, Hermione herself did not notice that she had a latent great ideal of eliminating inequality in the wizarding world.

In this regard, Li Lin only admired, and even more dared, telling Hermione that the house-elves did not even have a salary, and they were working voluntarily every day.
