Originally, I 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 has been 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 taken from the Demon Beasts, and they all have their own growth cycles!" Rolf deliberately exaggerated the difficulty of refining, wanting to increase the price.

"In that case, I still want to buy some materials from you to refine them myself, and I found that the kind of spell model you gave me must have extremely high-quality blood if you want to be engraved on the materials. ”

The quality of the dragon's blood should be enough, right? Maybe I should sneak home and put some blood from my own fire dragon?

What Rolf didn't know was that in Song Ye's world, they had a kind of bloodline wizard who exchanged the blood of demonic beasts for themselves, so in their world, it was almost impossible for high-level demonic beasts to see.

Rolf accepted the spell models and related materials of the Illusion Spell and the Traceless Stretching Spell from Song Ye, and after thanking him, he closed the friend system and devoted himself to the refining of the Invisibility Cloak.

In the Harry Potter world, dragons can be farmed, so dragon blood is not very expensive, but a commodity that can be sold in large quantities.

Rolf asks Eve to go to Diagon Alley to help him buy a batch, and by the way, he buys a new quill to use to inscribe a spell model.

The next few days were really as Rolf had imagined, and he couldn't get out of the Hufflepuff common room.

Even after the Christmas holidays, his invisibility cloak had no eyebrows, and he was constantly studying it.

Originally, he thought that it would be good to engrave on the 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, he was halfway through it when his hand trembled and the thread broke......

As a result, the dragon's blood, which was originally like a silk thread, scattered like droplets of water that had been broken.

Of course, it is impossible to fail this time, and what awaits Rolf next is to suffer the blows of the mother of success again and again:

At the critical moment, there is no time to follow the painting, which leads to forgetting the correct trajectory and failing.

I finally wrote down all the running tracks, but the ink of the quill was not enough, and 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 inscribe a traceless stretching spell into the quill, so that it could hold enough dragon blood.

As for why the Traceless Stretching Mantra can be engraved so easily?

The first is that it has a small area, and it can be successfully engraved with a little dragon blood with spiritual power, and secondly, it has few strokes, and it is far less complex than the spell model of the illusion spell.

When the ink was sufficient, I found that my mental power was not enough...... In the midst of one attempt after another, Rolf felt like he was going crazy.

It is definitely unrealistic to achieve a rapid leap in spiritual power in a short period of time, so he can only speed up the speed of the trajectory, so that the quills can complete the inscription of the spell model before the spiritual power is consumed.

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

Justin, who had just returned from the scared Christmas holiday, didn't sleep well all night because he slept next to Rolf, for fear that he would stab himself directly with his wand.

Finally, on the day Harry helped Gryffindor win Quidditch, Rolf succeeded in carving the spell model into the cloak of invisibility.

Rolf breathed a sigh of relief, Cedric had been asking himself what he was painting for the past few days, and in the professors' classes, he had been drawing by Bibi, and he couldn't listen to the class.

Fortunately, everything is finally over, and the invisibility cloak has been successfully refined by Rolf, and he will have a signature item in the future.

Rolf draped the freshly baked cloak of invisibility over his body, wanting to see how his one was different from Harry's.

He put on his cloak of invisibility and looked down at his feet, and they all magically vanished.

He walked quickly 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 strange picture, he quickly pulled the hood of the invisibility cloak to the top of his head, and he completely disappeared from his figure in the mirror.

But after some experimentation, he found that ...... Doesn't seem to be much different from Harry's invisibility cloak?

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

Otherwise, no matter how fast Rolf's hand speed is, his little mental power will not be enough to consume at all.

There was another thing he didn't know, the invisibility cloaks that exist in the wizarding world can only be used in the dark, and cannot be used for long periods of time. Harry was the only one that could be used in the daylight for a long time without revealing a shadow.

That's what makes Harry's invisibility cloak so precious.

Of course, these Rolfo don't know, and they are ashamed to sigh that they seem to have suffered a loss?

In the following days, Rolf began to devote himself to the refining of the space bag again, after all, Hagrid gave him a blanket of bird and snake hair, and he always felt that it was a loss if he didn't process it again.

To tell the truth, the space bag that was supposed to be difficult to refine was much easier for Rolf than the Illusion Spell.

I don't know if it's because of his affinity with the energy of the space element, anyway, after being destroyed by the invisibility cloak, it is simply not too easy for him to refine the space belt.

And the space bag doesn't need much hair, a blanket was easily dismantled into 30 space bags by Rolf.

It's good that the birthday presents for my friends in the coming year are ready, and I finally don't need to think about what to give.

You know, when it comes to giving gifts at Christmas, Rolf takes great pains to make sure it's practical, and it's exactly what his friends need.

But Rolf was thinking too much about it again, and March 1 was Ron's birthday, and after giving the space bag to Ron as a birthday present, he showed it off.

Then Rolf met Harry, Hermione, and Malfoy's resentful glances......

He had no choice but to give them the space bag in advance, and said that he would not give any more gifts when it was time for his birthday.

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

Of course, Rolf didn't forget Cedric, Justin, and Hagrid, but the materials consumed by Hagrid's space bag were equivalent to the amount of three other people's, which really made Rolf feel distressed.

But the wool comes from the sheep, and he's looking forward to what kind of blanket Hagrid will give him next.

By the way, he also went to ask the queen and Song Ye if they were interested in the space bag.

In Song Ye's world, although the space equipment is very valuable, he already has it, so he didn't buy it, but kept urging Rolf to refine another invisibility cloak, and patted his chest heroically, saying that the price is negotiable.

Is this a question of price? It's a question of how quickly the stealth beast lays its hair!

The queen is very enthusiastic about the space bag, after all, their world is only the world of micro-magic, and extraordinary power is 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.
