The Phantom Transfiguration Test Center is located on the sixth floor of the Ministry of Magic, which belongs to the Department of Magical Transportation, so it also contains the Floo Network Administration, the Broomstick Control Bureau, and the Portkey Office.

After entering this floor, it is like sitting in front of the fireplace in the living room, a warm breath fills the whole space, if it is winter, you will feel warm and comfortable, but unfortunately it is summer, you will be very eager to find the burning fireplace, and then extinguish it,

"It's especially hot in the morning, as there are plenty of spare fireplaces to light up the Floo network waiting to line up in the visitors' hall," Mr. Weasley explained, "and there aren't so many stoves set on on a normal day." (Note 1)

Mr. Weasley led Lawrence and the twins through the somewhat crowded passageway, and every wizard here looked miserable, but looking at the sweat on their foreheads, it was not incomprehensible,

They walked around the next corner, it was a little cooler, a high counter, there was a small step in front of it, and on the counter was a gold-trimmed sign that read "Phantom Migration Test Center", there was no human figure visible behind the counter, but it was spewing snowflakes one after another,

Mr. Weasley stepped up the small steps and tapped on the countertop, and a wizard emerged from behind the counter, waving his wand and shaking off the snowflakes that were spewing out.

"Three people? Name, age, is it your first time taking the exam?" The wizard's gaze swept over Mr. Weasley, and looked at Lawrence and the twins behind him, three forms flew up, and the quill on the side also jumped on the forms, with Mr. Weasley's assistance, the wizard quickly completed the registration form, and Mr. Weasley paid the registration fee,

"Didn't Hogwarts hold Apparition exams in Hogsmeade Village this April?" The wizard asked casually, trying to find something from the messy pile of papers,

"Ah, yes," replied Mr. Weasley, "'Triwizard Tournament' you know." (Note 2)

"Oh, yes, I remember Hogwarts as the winner, right?" The wizard understood, and he finally found what he was looking for, which was a round hole, and he rolled the registration form into a cylinder and stuffed it into the hole, and then three signs popped out of the hole, "It seems to be called ...... Lawrence. Rovander?"

The wizard grabbed the sign, looked at the name on it, turned his gaze behind Mr. Weasley, skimmed over the identical-looking twins, and finally stopped at Lawrence,

"Huh?" Mr. Weasley coughed, and the wizard woke up from a dream, handed the sign to Mr. Weasley, and then lay back in the chair behind the counter, and continued to use his wand to make snowflakes to cool himself.

"Your sign," Mr. Weasley stuffed Lawrence and the twins with the sign, and Lawrence saw his name on it.

"I'll look over there later," Mr. Weasley pointed to the notice board on the wall that said 'Ready', then pointed to another door, "call your name and go in there, understand?"

Lawrence and the twins both nodded,

"I'm asking you to go back 'there' as soon as the exam is over, you know what I'm going to say," Mr. Weasley said, looking worried, "I'd like to go to the International Department of Magical Cooperation, there will be enough room for Dunbury to speak." (Note 3)

"Ding." The bulletin board on the wall jumped, and the words on it changed to "George. Weasley',

"Go ahead." Mr. Weasley patted George on the shoulder, and left, George opened the wooden door on the side, and when he walked in, the door closed automatically, Lawrence and Fred looked at each other, and then walked to the chair on the side and sat down, and waited for a while, George did not come back, but with a "ding", the notice board on the wall was replaced with "Fred. Weasley',

"Uh, won't it come out of here?" Fred muttered, then pushed open the wooden door, so that Lawrence was left alone waiting outside, Lawrence stared at the notice board boredly, waiting,

"Hey, hey?"

Lawrence turned his head and found the lazy wizard hiding behind the counter lying on the counter shouting at him,

"There's a new French witch from the International Department of Magical Cooperation, and I heard she's a participant in the Triwizard Tournament," the wizard said, "as if it's called ......"

"Fleur?" Lawrence said,

"Yes, yes, that seems to be the name," the wizard nodded, "and the guys from the Department of Magical Cooperation have been bragging to us about how beautiful she is—she's really beautiful?"

"Ugh...... I think so." Lawrence replied,

"I heard you have a Christmas ball to welcome foreign guests, right?" The wizard said to himself, "Which lucky guy came with her to the ball?"

"Lawrence, is it convenient to disturb?" Hibiscus's voice came from afar,

Lawrence was in a trance,

"Your collar is a little crooked—" This time Fleur's voice sounded clearly,

Lawrence shuddered, he didn't understand what it was, and then he felt a cold touch on his scalp, and he came back to his senses to see that the wizard had come to him, and the snowflakes on the tip of his wand were constantly falling on top of his head,

"It's too hot, isn't it?" The wizard kindly said, "It's always like this in the mornings here."

"I...... Belch...... Thank you," Lawrence shook his head and glanced at the sign, "It's my turn, thank you."

Lawrence pushed open the wooden door, and a wizard was holding a parchment roll, and Lawrence saw a name tag hanging from his chest that read 'Waiki. Professor Tecros', and there is a small line below it, "Phantom Transfiguration",

"Lawrence. Rovande, seventeen years old, self-taught, first exam, okay," Tycros read as he looked at the parchment scroll, he stared at Lawrence for the final confirmation, "The Ministry of Magic has enough wizards around the target location you are heading to, if you accidentally 'split', as long as you don't deviate too far and stay calm, you can be saved, understand?" (Note 4)

Lawrence nodded, Waiki. Tekros handed him a photograph of a small grove of trees, and a building with a wizard waving his hand and a circular frame at his feet,

"This is the famous Muggle attraction, Regent's Park in London," Tycros introduced, "The spell to expel Muggles has been cast nearby, all you have to do is cast the illusion and the exact illusion to enter the circle, is there a problem?"

Lawrence shook his head, and Tycros pointed to the round frame behind him, motioning for Lawrence to stand over,

"Remember, goal, determination, calm." Tycros admonished, "You can start, take it easy."

Lawrence walked into the frame, and the moment he stepped into the frame with both feet, the frame glowed green, and Lawrence disappeared without a trace.

The illusion wasn't that comfortable, but Lawrence felt like he should?? Successfully and successfully, he landed firmly in a round frame, he felt that there seemed to be no missing parts on his body, and at the moment when he stood firm, the circle frame lit up with a green light,

"Greenlight, Lawrence. Rovander, Phantom Shifter Exam Passed—give me your exam nameplate." The wizard standing next to the round frame took a quill brush and wrote on the parchment, and then put the parchment back into his pocket along with the name tag.

"You've been allowed to use Apparition now," said the wizard, bending down to pick up the round frame on the ground, then pointing in one direction, "The Muggle Exorcism Charm will no longer work here in five minutes, and if you're not going to use Apparaguation to go home, there's a map around Regent's Park, but a map of Muggles."

The wizard disappeared with a bang, and Lawrence walked over to the map to see where he was.

"Regent's Park...... British Library ...... King's Cross,' thought Lawrence, it seems that this is not too far from Grimmauld Place, (Note 5)

But he was stunned, and he saw the familiar street names on the map, and Remus had told him that his parents were still living in London, and had not moved anywhere else.

Lawrence's eyes moved uncontrollably with the streets on the map, and then he felt like he had found the place that was supposed to be called 'home'.

───────

Note 1: In the original book, there is no such pattern and Floo network.

Note 2: In Chapter 21 of the sixth episode of the original book, you can know that you can take the exam if you are 17 years old before April 21, even if it is not the same year, but I think the dates will not be too different, everyone knows that the twins were born on April 1, but in the fifth episode of the original book, Harry confirmed that they passed the exam, so when I judged the Triwizard Tournament, there was no relevant course.

Note 3: There is no mention of time or place in the original book, only mentioning that Deng Buliduo gave a speech, and there was originally a plot of Deng Buliduo's speech, but I cut it.

Note 4: Charlie. Weasley's first test was five miles (about eight kilometers) off target, so I'm guessing maybe the target location wasn't in the Ministry of Magic? There will be at least some distance.

Note 5: Islington is located in the north of central London, King's Cross railway station is on his border, walk west across the British Library, you can reach Regent's Park, Islington first appeared in the third chapter of the Philosopher's Stone Scroll, as mentioned in the original book, King's Cross station to Grimmauld Square about twenty minutes.

Note 6: I am sorry to inform you that I made a low-level mistake, I am sorry for my elementary math teacher, correcting a number that I have been writing incorrectly, Lawrence was abandoned on his fourth birthday instead of his third. So I decided to stop for a month to show my responsibility (just kidding).
