...
Barty Crouch Jr., disguised as Mad-Eye Moody, once said during class that the Killing Curse used by young wizards could only make adult wizards bleed from their noses, and he also learned from Hagrid that most large magical creatures have a strong resistance to magic.
Therefore, the Killing Curse is not necessarily an invincible spell, just relatively so.
If the Killing Curse is facing an enemy with life force exceeding normal, and enough magic resistance, it can actually withstand the curse.
Like fire dragons, I haven't heard of any fire dragon being killed instantly by a dark wizard's Killing Curse.
The method for subduing fire dragons generally involves using the Stupefying Charm to temporarily blind them, followed by the simultaneous use of the Enchantment Charm by one hundred adult wizards, which can then subdue them.
If he incarnates as a giant in the Harry Potter world, he actually doesn't fear the Death Curse cast by ordinary dark wizards.
Even if he encounters too many black wizards, he's not stupid; he wouldn't just stand there and let himself be attacked.
George found, as he was leaving the library, that there was another door deep within the library, which was locked.
"Rebecca, what is that inside?"
He suspected that the locked door might contain something particularly powerful in its collection, like the restricted section deep within the Hogwarts Library.
Rebecca mentioned just now when introducing him to light magic that the previous generation of the Phoenix Tablet's president had created three of the strongest light-based super spells, which were said to be incredibly powerful.
Of course, Rebecca also said that it was just a rumor, because they had never seen the leader use them.
So, he had reason to guess that the door might be hiding the books of the three super spells.
Rebecca shook her head as George pointed at the door:
"I'm not sure either, but I've heard Mira say that only the leader can enter it, and there are very complex and powerful sealing spells on the door."
Once, Naruto was curious and tried to sneak in, but he was thrown back by the seal and knocked out, taking two days to wake up."
"When you become stronger, you must find an opportunity to sneak in and take a look."
George heard this and felt even more certain that his guess was likely true.
Returning to the ground floor hall, at this moment, besides Kana, who was drinking, and Mira Jin, humming a tune while cleaning, there were very few magisters left in the hall.
Some were busy with their tasks, while others were heading back to their dormitories.
The Fairy Tail Guild has dedicated dormitories for both male and female members of the guild in the town.
It's just a matter of paying some rent each month, and if you want to live in a better house, you can also rent a small villa in the town with your own money.
"You're here, I've left some food for you. Come and try it quickly."
Seeing George and his three cats arrive, Mira Jin put down the cleaning work, carried four dinners from the bar and put them on the table.
Mira Jin, in addition to being the guild's signature girl, is also the head of the guild's logistics. The bar's drinks, food, and other financial and errands of the guild are basically all handled by her.
"Mira sister, you're really great!"
Rebecca, who was short, ran into Mira Jin's arms and rubbed against her, and then started eating quickly. Rebecca often skipped dinner due to reading too late, and Mira Jin always left dinner for her.
"Thank you, Mira sister!"
Sarusuke, Dorelle, and George all thanked Mira Jin at the same time.
While George was preparing to sit down to eat, he looked at the half-cleaned up floor and thought for a moment before waving his hands and starting to chant spells.
"Clean as new!"
Instantly, the dirt on the table and the floor collected together and fell into the trash can by themselves, and the scattered glasses and utensils were neatly arranged back on the bar.
In an instant, the entire hall was clean and tidy.
"What is this magic?"
Seeing George's actions, the entire hall was cleaned up, and Mira Jin and the others were shocked and staring with wide eyes.
In the magic they know, there is no type of magic like this.
"It's the Eradication Charm, a domestic magic that I accidentally learned during my travels over the years. It's not for combat; it's only used for cleaning."
George made up an excuse and quickly picked up the spoon to enjoy the dinner.
Since he didn't plan to go out on missions and stay at the guild to learn and study magic, it was natural that he couldn't do nothing.
Helping to repair the hall and clean the place could also show his value and win the favor of everyone.
As for money, he has the Invisibility Stretching Charm, so he's not worried about not having enough. Making some space equipment and selling it separately in several cities could make more money than doing missions.
"It seems that you know quite a few magic spells, George."
Mira Jin sat next to George and couldn't help but reach out to stroke his cat's head.
George felt comfortable from the touch of the cat's head, but his rationality soon suppressed this pleasure and he quickly moved his hand away from Mira Jin's:
"Most of them are non-combat magic and can't compare to yours."
"You don't need to fight, just practice that repair magic well. If anyone dares to bully you, all the magisters in our guild will rip off their heads for you to kick around!"
Sarusuke smiled and said from beside him.
Although he said this with a touch of humor, it was not an exaggeration.
George is now a treasure of the entire guild, and anyone who dares to harm George would have to face the wrath of all the magisters, especially Guild Master Makarov.
Hearing Sarusuke's words, everyone laughed heartily.
George also helplessly shook his head. He thought it was a good thing too, at least he had a reliable back-up in this world and didn't have to worry about safety issues.
And so, with eating and chatting, it was already dark by the time they finished.
Lock up the guild's gate, Mira Jin carries drunken Kana and everyone walks together towards the town center.
Mira Jin and Rebecca, and the others are going back to the guild's dormitory, while George returns to the hotel. They were together for the first half of the journey, so they walked together.
After returning to the hotel, George started to summarize the magical knowledge he had learned today and began the basic practice of giant magic, attempting partial gigantification of his body.
The best way is to start with easy parts like fingers and toes, or even little George is fine.
In the next few days, George was able to settle down and focus on magic learning and research.
Every day, George was the first to arrive at the guild, then he would go into the library to read books or ask Master Makarov questions about magic in the hall, and occasionally help fix the guild hall and clean.
At night, most of the time he would leave with the Rebecca Squad, and when the Rebecca Squad wasn't at the guild, it was just him.
With the passage of time, he gradually became familiar with the magisters in the guild.
He learned some things he didn't know before.
Like Naruze's magic, it wasn't a simple fire-based spell, but a dragon-killing spell used by dragons. It is much stronger than ordinary fire-based spells and can consume all flames, thus enhancing its own magic power.
So normal fire-based magisters would be at a disadvantage when facing Naruze, who uses dragon-killing magic.
Narazu was actually raised by a dragon, and his magic was taught by the dragon. Just one day, the dragon that raised him disappeared, and he accidentally joined the Fairy Tail guild.
He could be considered a human-dragon.
George sometimes wondered if his wand in this world could fall on Naruze.
Using Naruze's hair as the core of the wand should be a good choice.
