With the knowledge of the two worlds, Rowe soon improved some potions and created a potion that increased his magic power, which Rowe named ...... Mana Potion.

This mana potion not only increases mana, but also replenishes the deficit mana.

In a sense, it's a lot like the blue bottle in the game, but better.

It is worth mentioning that the reason why Rowe was able to create a magic potion was that in addition to his own knowledge, the person who should be thanked the most was Dumbledore.

If it weren't for the fact that he personally provided Luo Wei with a sum of money to buy all kinds of expensive medicinal materials, Luo Wei would not have been able to make this batch of magic potions in a short period of time.

The first batch of mana potions was made in a total of thirteen bottles.

Luo Wei became the first experimenter.

After he drank a bottle of magic potion, he immediately used the chaotic power in his body to devour the medicinal power of the magic potion, and the chaotic power swelled at a speed visible to the naked eye.

It's just a small bottle of magic potion, which is comparable to Luo Wei's penance for a month.

In a sense, this magic potion works really well.

Without saying a word, Luo Wei poured all the remaining mana potions into his mouth, and then used the power of chaos to devour the mana potion.

The chaotic power in the body also soared a lot because of this, directly doubling.

This gave Rowe hope to become stronger.

He decided to make mana potions in bulk, but these required money, as there were three types of dragon's blood and several expensive herbs among the raw materials for mana potions.

The cost of a bottle of mana potion is about a hundred gold galleons.

By the way, the Golden Galleon is the wizarding currency of the Harry Potter world, and it is made of gold. On the edge of each Galleon is a column of numbers representing the number of the currency engraved by the Gringotts coinage fairies.

Hundreds of gold gallons is not a small amount of money.

If Rowe remembers correctly, in this world, the price of a wand is only a few gold gallons, and the horn of a unicorn is twenty-one gold gallons...... It can be seen that the Golden Galleon is really valuable.

Even Dumbledore couldn't have given Lowe so much money unconditionally.

If Rowe wants to make a lot of magic potions, he must get enough money.

But this is not difficult for Rowe, because Rowe is proficient in the art of turning stones into gold and can turn stones into gold.

So he turned a stone weighing several tons into a piece of gold and gave it to Dumbledore, hoping that Dumbledore could use the large gold to go to Gringotts and exchange it for gold Galleons.

When Dumbledore saw this oversized piece of gold, he couldn't help but push his eyes on the bridge of his nose and said, "This is really...... Stunning. ”

Luo Wei smiled and didn't speak.

Dumbledore sighed and said, "Okay, I'll help you exchange this piece of gold for gold Galleons, but I hope it's only this time, Rovi, if you're often so high, it's easy to cause shocks and shocks to gold gallons." ”

Luo Wei thought for a moment, nodded and said, "Yes." ”

Dumbledore smiled with satisfaction, and left Hogwarts for a trip to Gringotts, where he exchanged the huge nugget for gold Galleons.

It was about 200,000 gold galleons exchanged, enough for Luo Wei to use for a while.

Without hesitation, Luo Wei swept away all the raw materials on the market to make magic potions, and then hid in his room and began to make magic potions frantically.

At the same time, Hogwarts sent off a group of students for the summer of the year.

Dumbledore didn't get any time to relax.

Because the new students will be enrolled as soon as the summer vacation is over, he now needs to handwrite a letter of invitation to the new students.

"Dear Mr. Potter,

We are pleased to inform you that you have been approved to attend Hogwarts School of Witchcraft and Wizardry. Enclosed is a list of the required secretaries and equipment.

Semester is scheduled to begin on September 1. We will wait for your owl to hear back from you by July 31.

Vice-Principal (Female)

Minerva McGonagall. ”

In addition to this invitation, there are some things that new students need to prepare for admission, such as a three-sided plain work gown, a plain pointed hat to wear during the day, a pair of protective gloves, a winter cape, and so on.

Of course, textbooks, wands, crucibles, glass or crystal vials, telescopes, brass balances are indispensable.

And pets.

For example, an owl or a toad will do.

……

On the other hand, Luo Wei spent the entire summer making magic potions in his room, and he was able to make a batch of magic potions every day.

Then spend a day refining the mana potion.

Spend a day making new mana potions.

And so on and so forth.

When Luo Wei made all the raw materials into magic potions, and then absorbed all the magic power, the chaotic power in Luo Wei's body increased by at least twenty or thirty times compared to before.

Now he can even proudly tell everyone that his strength has improved by leaps and bounds, and with the support of the powerful chaos power, the power that Luo Wei can exert has been greatly enhanced.

Now he was no worse than Dumbledore.

If two people fought, Dumbledore wouldn't necessarily be his own opponent.

After all, Rovi's chaotic power is much stronger than Dumbledore's magic power, and now he has the strength to destroy a Ministry of Magic, and even coerce the entire wizarding world.

You can walk sideways wherever you are.

And all this, Luo Wei only spent one summer vacation.

When Rowe walked out of his room, the summer vacation had come to an end, and it was only a few days before Hogwarts reopened and new students were enrolled.

During the past few days, everyone has been busy, including Dumbledore and Professor McGonagall.

After Rowe came out of his room, Professor McGonagall arrested Rowe without saying a word, hoping that his assistant professor would play a role in some way.

Lowe didn't give up, and for the next few days, he followed Professor McGonagall to help her with trivial but troublesome matters.

And just like that, a few more days passed in a blink of an eye.

On this day, the summer vacation finally ended, and the senior students returned to Hogwarts one after another, and all they had to do was to wait quietly for the new students to enter the school.

The Great Hall of Hogwarts is beautifully furnished, suspended in the air one by one, like a starry sky, dotting the entire Great Hall.

And Lowe wants to follow Professor McGonagall to pick up the newcomers who have just entered the school.

When he arrived at the gates of Hogwarts, he saw a crowd of children gathered in droves.

This naturally includes the protagonists of the Harry Potter universe...... Savior Harry Potter.
