Hogwarts: I'm the only one who cultivates immortality

"boom!"

With a deafening explosion, the roof of the Hogwarts dining room soared into the sky and quickly disappeared into a small black dot. About an hour later, the Azkaban attack siren sounded because they were hit by a roof. attacked.

Of course, since the guards of Azkaban are dementors, there is nothing to lose.

On the other side, the 'restaurant' Ye Feng nodded in satisfaction, seeing that the roof was blown to nothing but the main structure was not damaged at all, and the main structure was even stronger than before.

"Perfect! Next, we just need to arrange the real ceiling of the starry sky and we're done." Ye Feng murmured, controlling the brush and the small bucket of materials that still contained half of the magic circle and started working again.

Blowing up the roof is just the first step. Next, we need to arrange a magic circle to seal the dome. Otherwise, wind and rain will affect the students eating below. The dome will probably be repaired the next day. , so Ye Feng had to install 'glass' on top of the dome.

This is very simple for Ye Feng, just draw a few isolation magic circles on the roof, so that not only the dome is a real transparent starlight roof, but also can isolate rainwater, which belongs to the kind where light can enter, but wind and rain cannot enter.

But Ye Feng had just started working when a dark-faced Dumbledore appeared in front of him.

"Student Ye Feng, can you explain what you are doing? If your explanation doesn't satisfy Hogwarts, you can fix the roof yourself."

Seeing that Dumbledore's face turned dark, Ye Feng quickly explained: "Principal Dumbledore, don't you think the ventilation in the restaurant is a bit poor? Our barbecue meeting has only started for half an hour, and the oily fume inside is already annoying." It's gone, so I'm ventilating my classmates."

Hearing Ye Feng's words, Dumbledore's face darkened even more.

"You mean, you lifted the roof off just to ventilate?"

"Yes." Ye Feng answered naturally.

After answering, Ye Feng saw that Dumbledore's face turned from black to white, and quickly explained again: "Actually, it's not entirely because of the need for ventilation. Apart from the need for ventilation, I think the original fake starry sky ceiling is not very good. , so I plan to tear down the roof and make it real."

"But Principal Dumbledore, don't worry, the formation is almost finished. After the formation is completed, you will not only get a real starry sky ceiling, you can really see the sky outside in real time, and you don't need anything to blow the wind." If it’s raining, if you’re in a hurry, you can fly directly from the roof.”

"Of course, as long as you are a professor at Hogwarts, you can directly enter the restaurant from the outside of the roof."

Hearing Ye Feng's words, Dumbledore's face that was about to turn white slowly returned to normal, and it was also at this time that Dumbledore discovered that the runes drawn by that brush were extremely mysterious, so mysterious that even Even he could only understand half of it, which made him extremely shocked.

"Ye Feng, can you tell me where you learned the things you draw now? I don't think any teacher in school has taught you these things." The reason why Dumbledore dared to be so sure was because He didn't even learn it himself, and even he didn't understand it, so how could other people in the school understand it?

Ye Feng looked at Dumbledore whose face became serious in an instant and said indifferently: "I learned it in the library myself, those things are quite difficult, and it took me a full week to understand them all. "

Dumbledore: (°Д°)

"One... a week?"

"One week."

"Crack it!"

Dumbledore's jaw was dislocated because of Ye Feng's accurate answer, and he even forgot that the books that Ye Feng said were only found in the restricted area, because this is really too incredible. I know that he studied it carefully for a month before he managed to get started and understand a little bit.

"What a...little monster!"

Ye Feng didn't know what Dumbledore thought of him, because those magic formations were really not difficult for him. After all, he had obtained many cultivation formations from the system before, and some of those formations were just arranged The range is comparable to a super big city, so compared to the Immortal Dao formations, these magic formations can only be regarded as pediatrics for Ye Feng.

Of course, although he has learned a lot of those formations, due to the lack of various materials, he can only arrange a gathering of spirit formations at most now, and if there are more, the material inventory in his hand will not be able to support it.

So don't look at Ye Feng as an immortal cultivator at all, but he actually knows a lot of things, but he is too shy to show many things, and this is a magical world, a lot of materials They are not the same as the materials for cultivating immortals, and he still needs to try a little bit to know how to use them.

Dumbledore didn't know what to say for a long time because of the shock, and Ye Feng was busy drawing the magic circle again, so the roof fell silent for a while.

However, Ye Feng's drawing speed is still very fast, so after just over a minute, a dazzling light quietly bloomed from the roof.

"Okay, from now on our restaurant will have a real 'Starlight Roof'."

Hearing Ye Feng's words, Dumbledore quickly turned to look at the empty roof, and his eyes brightened when he saw the transparent roof with a little trace still visible.

"It seems that next year our Hogwarts will have more features to attract young wizards, and there is no need to cancel the monthly barbecue meeting."

Although Ye Feng lifted the roof, he did repair the roof. Although the 'roof' is no longer visible, it does exist, so Ye Feng was not punished, but when Dumbledore the next day When Lido saw Azkaban being attacked by a 'roof' from the Daily Prophet, his heart skipped a beat.

When Dumbledore saw the rather familiar roof in the newspaper picture, several black lines appeared above his head.

"This guy can really cause trouble! But it's so far away, and it's not just the roof of Hogwarts that looks like this, no one should guess that this roof belongs to Hogwarts, right?"

"Why don't you go and find out?" Dumbledore, who was a little uneasy, finally decided to find out the news, and Ye Feng, after eating and drinking, was returning to his dormitory and was working hard.

Thanks to the inspiration from drawing the magic circle after the roof was blown up, Ye Feng finally knew what gift to give to Zhang Qiu, his family and Harry.

Now he has no materials to practice magical artifacts and immortal artifacts, and he can’t refine elixir because he doesn’t fully understand the properties of the materials and medicinal materials, but there is no problem with talismans and the like, so Ye Feng plans to refine some talismans for them. .

Of course, the talismans sent in couldn't be ordinary one-time talismans drawn on yellow paper. What he wanted to make were jade talismans and peach talismans that could be used many times.

But Ye Feng probably didn't know it, because of his flash of inspiration, a new 'sect' appeared in Hogwarts in the future, the Talisman Sect.
