London, England.
Inside a luxuriously decorated room.
Lucas was sitting by the fireplace, an unopened letter in his hand.
On the side, a snow-white owl was standing on the table with its head tilted and combing its feathers.
When he opened the letter, the whole article was written in beautiful and coherent English.
Fortunately, Lucas had lived in this 1980s London for eleven years, so it was easy to translate.
"Hogwarts School of Witchcraft and Wizardry
Headmaster: Albus Dumbledore (President of the International Confederation of Wizards, Level 1 Sir Merlin, Grand Mage, Chief Mage of Wizengamot)
Dear Mr. Lucas:
We are pleased to inform you that you have been admitted to study at Hogwarts School of Witchcraft and Wizardry, and we enclose herewith a list of required books and supplies.
The semester is scheduled to start on September 1st, and we will be waiting for your owl to hear back by July 31st.
Vice Principal (Female)
Sincerely, Minerva McGonagall"
This was only the first sheet of the envelope, and there was a piece of paper filled with all kinds of supplies needed for the start of school and books for learning magic.
The letter also bore the school's emblem: snake, lion, badger, eagle.
Seeing these familiar representations, Lucas understood immediately.
Eleven years ago, he had traveled to London in the 1980s. Although he was an orphan, he possessed a rich legacy and owned a house in London.
Originally, he thought he was simply reborn to London in 1980, but he did not expect to be reborn into the world of Harry Potter.
Thinking of this, Lucas couldn't help but fall into contemplation.
He also had his own Gold Finger when he came to this world.
A traveling frog in a ruffled hat.
This was a game that had been popular for a while in his past life. Players had a cute green frog who would travel from time to time, sending photos and bringing home specialties.
However, the frog cub owned by Lucas was not just in this world.
Instead, it was a journey to various worlds, each bringing something different.
Lucas's frog cub had gone on a trip three days ago.
Today was the day when the frog cub would come back.
What Lucas didn't expect was that he would receive a notice from Hogwarts today.
It was also a nice surprise for him, at least giving him clarity about what kind of world it was.
"I don't know which world the frog cub traveled to this time."
"Hopefully, I can receive something nice."
After giving the owl some food and handing it the written reply, the owl passed through the window and disappeared into the night.
Now he was waiting for a reply from Hogwarts School.
Lucas lay back on the couch and picked up some pictures that were on the table.
The photos were sent to him by the frog cub during its travels, and they were marked with the date they had come back - which was today.
The building in the photo was very peculiar. It was different from the current high-rise buildings. Even Lucas, who had lived two lives, had never seen it.
One of the most attractive photos showed a young man with flames on his fingers, laughing heartily.
"It seems that the world the frog cub traveled to is very unusual."
Thinking of this, a smile appeared at the corner of Lucas's mouth.
Boom—
At this moment, a soft sound caught Lucas's attention.
Looking up, a green frog the size of a fist was lying on the table.
Behind it was a bulging package.
"Cuck!"
With a frog croaking, the frog cub undid the package behind him, revealing a golden crystal inside and then slowly pushed it in front of Lucas.
"Quack!"
The frog cub pointed to his mouth, indicating that he was hungry.
Lucas put the food that had been prepared in front of the frog cub.
"Thanks a lot!"
Touching the little head of the frog cub with his hand, Lucas turned his gaze to the golden crystal on the table.
The crystal was golden and prismatic, with arcs of silk accompanying its surface.
"What is this?"
Lucas didn't touch it rashly.
He didn't have the invincible body that traveled the world like the frog cub, and some things were better not to touch until they were clear.
At this time, a line of text appeared in Lucas's vision.
That was an introduction to this crystal.
[Thunder Dragon Slayer Crystal - a special product from the world of "Fairy Tail"]
[Effect: Implant the Thunder Dragon Slayer crystal into your body to acquire Thunder Dragon's magic and powerful Thunder Dragon physique!]
[Usage: If no one performs the implantation operation for you, swallowing may be a good choice.]
"This... brought back a literal Dragon Slayer Crystal!?"
Lucas, who had seen Fairy Tail in his previous life, naturally recognized this kind of thing, and it was indeed a special product of that world.
He just didn't expect that frog cubs could bring back this kind of thing!
Lucas looked at the golden crystal entwined in the arc, and his pale blue eyes flashed with fiery heat.
After mastering this Dragon Slayer crystal, he could be regarded as having a strong capital in this wizarding world.
Without further ado.
After seeing the effect of this crystal, Lucas hesitated for a moment, and then picked up the crystal.
The entangled arc made him feel a little numb, and then he threw the whole crystal into his mouth.
As for the choice of surgery to implant this crystal, it was impossible in every respect.
The moment it was put into his mouth, the crystal exploded, and the tiny arc instantly wrapped around Lucas's body.
Resisting the discomfort and swallowing the crystal, Lucas only felt that his body began to tear.
His pale blue eyes were replaced by pure gold, and the whole person was bathed in lightning.
Boom—
A huge thunder crashed down, piercing the dark night.
This went on for about half an hour.
When Lucas came back to his senses again, he found that the furniture around him had turned into coke and powder.
Thanks to that rich legacy, this didn't make Lucas feel bad.
The fireplace, which was burning with flames, was completely ripped apart, and the only light was the occasional arc of electricity from Lucas.
After the frog cub on the side had eaten the food, it had already returned to its den and fallen asleep.
The thunder and lightning just now did not affect it at all.
Lucas turned on the light in the room and walked slowly to the floor-to-ceiling mirror.
Blonde curly hair, light blue eyes, and a handsome face were enough to make many people envy him.
After careful observation, Lucas found that he was much taller than before, and his body was more beautiful.
"The Power of Thunder Dragon Slayer Crystals..."
Lucas snapped his fingers, and an electric current suddenly appeared in the air
