The Plane Merchant of Hogwarts

I originally thought that it would take a long time for Song Ye to optimize the spell model, but what I didn't expect was that the friend system would light up again the next day.

"The model is optimized, but we don't have the materials here. Is it easy for you to refine it?" Song Ye asked tentatively.

"Easy? How is it possible? These materials are all collected from Warcraft, and they all have their own growth cycles!" Rolf deliberately exaggerated the difficulty of refining, hoping to increase the price.

"Is that so? I also want to purchase some materials from you to refine them myself, and I found that the spell model you gave me must have extremely high-quality blood if it is to be engraved on the materials."

Extremely high-quality blood? The quality of dragon blood should be enough, right? Maybe you should sneak home and drain some blood from your own fire dragon?

What Rolf didn't know was that in Song Ye's world, they had a blood wizard who exchanged the blood of Warcraft into his own body, so in their world, high-level Warcraft was almost difficult to see.

Rolf accepted the spell models and related information of the Illusion Body Curse and the Traceless Stretch Curse from Song Ye. After thanking him, he closed the friend system and devoted himself to refining the invisibility cloak.

In the Harry Potter world, dragons can be farmed, so the price of dragon blood is actually not that expensive. Instead, it is a commodity that can be sold in large quantities.

Rolf asked Eve to go to Diagon Alley to purchase a batch for him, and by the way bought a new quill to use to engrave spell models.

The next few days were exactly as Rolf imagined, and he was unable to leave the Hufflepuff common room.

Even until the end of the Christmas vacation, his invisibility cloak had no clue, and he had been working hard on it.

Originally, he thought he could just engrave it on his cloak according to the spell model that Song Ye had optimized for him, but reality woke him up again.

The first time he drew a spell model, halfway through the drawing, the line broke due to shaking hands...

As a result, the dragon's blood, which was originally like a silk thread, scattered like water drops with broken threads.

Of course, it is impossible to fail just this time. What awaits Rolf next is to be hit by the mother of success again and again:

At the critical moment, there was no time to follow the drawing, resulting in forgetting the correct track and failing.

I finally wrote down the entire running trajectory, but the ink of the quill pen was not enough, so I failed.

Rolf had no choice but to put down the refining of the spell model and transform the quill.

He used his mental power to carve a traceless stretching spell into the quill so that it could hold enough dragon blood.

As for why the Traceless Stretching Spell can be inscribed so easily and successfully?

The first is that it is small in area and can be successfully engraved with mental power and a little bit of dragon blood. The second is that there are few strokes and is far less complex than the magic model of the Illusion Body Curse.

After he had enough ink, he found that his mental power was not enough... As he tried again and again, Rolf felt like he was going crazy.

It is definitely not realistic to achieve a rapid leap in mental power in a short period of time, so he can only speed up the trajectory so that the quill can complete the inscription of the spell model before the mental power is exhausted.

So he took the straw paper again and began to practice his writing speed every day. This also led to one day when Rolf was dreaming, his hand was still sketching the spell model in mid-air.

Justin, who had just returned from the Christmas vacation, was so frightened that he couldn't sleep well all night because he was sleeping next to Rolf and was afraid that he would just stab him with the wand.

Finally, on the day when Harry helped Gryffindor win the Quidditch match, Rolf successfully engraved the spell model on the invisibility cloak.

Rolf breathed a huge sigh of relief. In the past few days, Cedric had been asking him what he was drawing. In the professors' classes, he had been comparing his drawings and couldn't even listen to the lessons.

Fortunately, everything is finally over. The invisibility cloak was successfully refined by Rolf, and he will have a signature product in the future.

Rolf put the freshly made invisibility cloak on himself, wanting to see the difference between his one and Harry's.

After he put on the invisibility cloak, he looked down at his feet, and they magically disappeared.

He quickly walked to the mirror and saw that in the mirror only his head was hanging in the air, and his body was completely invisible.

Seeing this weird scene, he quickly pulled the hood of the invisibility cloak over his head, and his figure in the mirror completely disappeared.

But after some experiments, he found that...it seemed to be no different from Harry's invisibility cloak?

What he didn't know was that a first-year wizard could successfully refine an invisibility cloak before he was promoted to a first-level wizard. This was all because of the optimization of the spell model, which simplified many unnecessary lines.

Otherwise, no matter how fast Rolf's hands were, his mental energy would not be enough to consume.

Another thing he didn't know was that the invisibility cloaks that exist in the wizarding world can generally only be used in the dark and cannot be used for a long time. Only Harry's one can be used during the day for a long time without exposing the shadow.

This is why Harry's invisibility cloak is so precious.

Of course, Rolf didn't know this, and he still felt shamelessly lamenting that he seemed to be at a disadvantage?

In the following days, Rolf began to invest in refining the space bag again. After all, Hagrid gave him a blanket of bird and snake hair, and he always felt that he would be at a disadvantage if he didn't process it again.

To be honest, the space bag that was supposed to be difficult to refine was actually much easier for Rolf than the Illusion Body Curse.

He didn't know if it was because of his affinity with the energy of space elements, but after being devastated by the invisibility cloak, it was not easy for him to refine the space belt.

Moreover, space bags do not require much hair. Rolf easily dismantled a blanket into 30 space bags.

Very good, the birthday gifts for friends in the coming year have been prepared, and finally there is no need to think about what to give.

You must know that when giving gifts at Christmas, Rolf takes great pains to make sure they are practical and exactly what his friends need.

But Rolf thought too much again. March 1st was Ron's birthday. After giving Ron the space bag as a birthday gift, he showed it off everywhere.

Then Rolf met the resentful looks of Harry, Hermione and Malfoy...

He had no choice but to give them the space bag in advance and made it clear that he would not give any more gifts until their birthday.

Everyone didn't care about that, but happily experimented with the function of the space bag.

Of course, Rolf has not forgotten Cedric, Justin and Hagrid, but Hagrid's space bag consumes the same amount of materials as three other people's bags, which really makes Rolf feel distressed.

But wool comes from sheep, so he was looking forward to what kind of blanket Hagrid would give him next?

By the way, he also asked the Queen and Song Ye if they were interested in the space bag feeling.

In Song Ye's world, although space equipment was very valuable, he already had it, so he didn't buy it. Instead, he kept urging Rolf to refine another invisibility cloak, patting his chest boldly and saying that the price was negotiable.

.

Is this a question of price? This is a question of the speed at which invisible beasts produce hair!

The queen is very keen on the space bag. After all, their world is just a world of micro-demon, and extraordinary powers are rare.

But after such a long search, the Queen did not collect anything of value, so she had to work harder to find the items that Rolf was interested in.
