Ever since learning the Patronus Charm, Natsuki has begun to test its effects on dark creatures other than the Eater of Souls.

His dragon-shaped Patronus can deal some damage to Ginger, which means that this Western spell can drive away the dark creatures of the East.

Yes, it's just to drive, not kill, which is why the attack power of non-dark wizards in the wizarding world is very limited.

They can only chant anti-spells or rely on their physical fitness to avoid the spells of the dark wizards, but it is good to be able to drive them away, after all, the Maoshan technique in the psychic zombie films of the Uncle Ying series has a very limited effect on dark creatures such as vampires.

If Natsuki encounters a vampire in the future, in addition to physical attacks, he can also cooperate with spells, so that the attack method is not too simple.

Walking in the heavens, what strange creatures in the film and television world can't be seen, and the traverser can only be invincible if he takes precautions.

In addition to the Patronus Charm, Natsuki spends his weekends with Professor Quirrell and Voldemort learning new spells.

The "relationship" between the teacher and the student has increased a lot in just a few weeks, although both sides have their own goals.

It's another weekend, but this time Natsuki doesn't go to Quirrell's office because the Quidditch Cup has arrived.

This time it was Gryffindor playing Slytherin, and it was Harry Potter's first Quidditch match.

Eating the Golden Snitch and slashing 150 points for Gryffindor, it is this time that the battle to fame is said to be quite classic, not to mention the peak duel between Snape and Quirrell in the audience.

But Natsuki wasn't interested in this competition, and he had more important things to do.

As for what it was, of course, it was to take a good "tour" of Snape's private storage room while he was not moving.

No way, no matter how talented a genius is like Natsuki, people's energy is limited, and most of his spare time is spent practicing spells with Quirrell and himself.

This meant that Natsuki had made a trade-off, giving up the Potions class, where ingredients were not easy to find in other worlds.

Moreover, after "getting acquainted" with Quirrell, his relationship with Snape became relatively cold, and Natsuki didn't expect to learn a little bit of advanced content from Snape.

Even in the underground classroom of Potions class, there is a cheat like the half-blood prince's notes in the cabinet.

If you don't study, if you want to achieve your goal, you have to use some crooked ways.

The general plot of the Harry Potter series of movies, Natsuki basically remembers, and some details are not very clear, but in the fourth part of the movie, Harry can breathe underwater, and he still knows.

Neville stole the cheek grass from Snape and gave it to Harry, for which he was threatened by Snape, and the meme of the three drops of the elixir to get you home for the New Year came from.

Truth elixir is one of the purposes of Natsuki's trip, although it is a little immoral, but Natsuki will still leave a reward for Snape, he used to be too poor to do anything, but as a billionaire in the future, Natsuki has become generous.

At this moment, Hogwarts was quiet, and almost everyone, including Dumbledore, went to the Quidditch arena, and Natsuki had a fire talisman in his hand through the main corridor of the castle.

The teacher and students are not there, but those ghosts in the castle are still there, and there is no difference between being seen by them and being seen by others, unless Natsuki directly makes them scatter, otherwise the news will definitely leak out.

Fortunately, Natsuki has a way to avoid them, or let them automatically stay away from him, and the fire talisman blessed in his hand is burning slowly, just like a fire break in martial arts, and the sparks release the supreme yang qi that terrifies the ghosts.

In this way, the ghosts of the four major colleges were not encountered, and Natsuki managed to make it to Snape's private storeroom, located in a small cubicle in a corridor.

"Alaho Cave Open!"

With a flick of the wand, the padlock on the door opened at once, Snape didn't leave any anti-spells on the lock, Natsuki had already checked it with the eye of the sky in advance, and there was still a plug-in method for the traditional Western magic Natsuki.

The Heavenly Eye Technique in the Maoshan Technique was originally only used to observe those invisible Yin Evil Ghosts, and some Yin Qi and evil qi, but who would have thought that with the blessing of the Heavenly Eye Technique, Xia Shu would be able to see the fluctuation of magic power.

In this way, the trap laid by magic Natsuki only needs to "glance" to find it.,Maybe this is the convenience of the traverser.,A small spell small object in one world to another world is the existence of a BUG.。

Walking into Snape's storage room, which was only two or three square meters, he saw shelves against the wall on three sides filled with large and small bottles and cans.

The larger jars contained the raw materials for potions such as aconitum and white fresh, while the smaller jars were half-finished products, and only the small bottles on the right-hand side contained the finished potions.

But Snape didn't put a label on the finished potion, which was a bit of a headache, Snape himself knew what color bottle was in it but no one else knew!

Forget it, let's end it in a nest! When I have the opportunity, I will find a miscellaneous drug like the Red Turban Army.

Thinking of this, Natsuki directly unfolded a blank section of the storage scroll.

"Seal!"

The potion on one wall disappeared in an instant, and a large word "medicine" appeared in the blank part of the scroll.

In other words, the world of Harry Potter also has storage equipment, especially related spells-Traceless Stretching Spell, which is similar to the scroll sealing technique, which is a space-based spell.

It's just that because of the particularity of space, space equipment and space equipment can't be stacked with each other, otherwise wouldn't it be nice to fill a box of scrolls with a suitcase that has cast a traceless stretching spell?

Wait, next Saturday I'll ask Quirrell about the Traceless Stretching Spell, and as a collaborator in his last world, Orochimaru, Natsuki appreciates his inquisitive attitude towards the mysteries of the technique.

Technique, it is never too much, people's energy is not enough, life is not enough, that is all an excuse, they have become a traverser, and even immortality can't be begged, so there is nothing to be a traverser.

And in this world, the opportunity for Natsuki's immortality has appeared, and it depends on his own ability whether he plans or not.

Leaving a pack of two hundred gold gallons on the shelf, Natsuki closed the door of the storage room, the raw materials of the potion are not expensive, the expensive is Snape's labor, taking the elixir as an example, in addition to taking half a month to make the potion fully mature, it will take a month to adjust the potion, and Snape has put a lot of effort into these potions.

So two hundred Golden Gallon Summer Trees feel that it is worth it, after all, in Diagon Alley, these things Summer Tree can't buy with money.

After doing all this, Natsuki left the castle and hurried back to the Quidditch arena as fast as he could, having just shown his face and disappearing, and had to go back before no one noticed his disappearance.

"Yay!"

Wrapped in his green scarf, Natsuki had just returned to the Slytherin stands, only to hear a tsunami of cheers from Gryffindor, and the Slytherin side was as dejected as his dead parents.

Harry Potter, who stepped off the broom, grabbed the golden snitch stained with his saliva and signaled to everyone, and at this moment he became the hero of Gryffindor.

This may be the charm of Quidditch, although Natsuki didn't quite understand, his eyes left Harry, Natsuki looked at Snape, Snape, who had been burned in half of his robe, was once again ruined, but the money Natsuki left him was enough to make a lot of new robes.

He wasn't the key, the key was Quirrell in the rows behind him, Bambi's face didn't have a frightened little look on his face, there was just anger hidden in the corners of his eyes.

Voldemort must have been even more disappointed in him this time! There is such a servant who has not achieved enough and has more than enough to lose, if it were Xia Shu, he would be quite disappointed.

However, although the work was almost done, Quirrell was still a good teacher, and in the following "make-up class", Natsuki successfully learned the Traceless Stretching Charm, although this is also a spell that can only be used with the approval of the Ministry of Magic, but both Natsuki and Quirrell coincidentally forgot about this.

On Christmas Eve, Natsuki in the dormitory is packing his belongings into the box where he has just cast the Traceless Stretching Charm.

In the blink of an eye, Hogwarts is on winter vacation, not long, only three or four weeks, but it is enough for Natsuki.

Yes, he was going to do something, and maybe it would be in the Prophet newspaper at the end of the holiday!

"Xia, you're going back this time?"

Seeing Natsuki pushing the salute towards the train, Hermione also chased after her.

"Go back, my dad should miss me!"

I don't know if my father wants to think about Natsuki, but it's enough to deal with Hermione.

"Harry and Ron can't go back this holiday and can only stay at school!"

Gryffindor's "Big Three" has taken shape, and now Hermione is inseparable from Harry and Ron, this is the powerful influence of the will of the world on the plot!

I don't care about these Natsuki, the only thing I care about is probably Gay Deng's Christmas gift to Harry, the invisibility cloak is one of the three Hallows of death alongside the Elder Wand and the Resurrection Stone, but unfortunately there must be a ban set by Dumbledore on such things, and Natsuki doesn't want to face Dumbledore so early.

The train carried the group back to King's Cross Station, and after separating from Hermione, Natsuki also returned to his home on Baker Street, because Natsuki had cast a dusting spell before leaving, and the house was still clean.

I didn't stay idle all night, and the next day Natsuki went to the street to go shopping, but this time I didn't go to Diagon Alley, but to an outdoor specialty store.

As for the problem of how to buy these things for a little ghost, Natsuki directly solved it with the compound decoction, and on the night of his return, Natsuki grabbed a group of local traffickers and tried out all of Snape's medicines.

In addition to the elixir and polyjuice decoction, there is also a small bottle of elixir that can bring luck to people.

Maybe it will be useful next time the system issues rewards?

"Huh~~"

The effect of the compound decoction has subsided, and Natsuki has changed from an adult back to his original little bit, but everything that needs to be done has been done.
