[HP] When a son dresses up as an old man

The surroundings were quiet, and there was a crisp sound of the wand landing. James slowly retracted the wand and put it away. His eyes met Lestrange's surprised gaze. Lestrange couldn't believe his eyes. How can this be?He and Potter were clearly equal in strength, how could he be disarmed by the opponent in a pre-emptive situation? Since when did Potter's magic speed get so fast!

"This classmate." James's gentle voice sounded.

"Class is about to start, please sit back in your seat." James' tone sounded like he was educating a disobedient child.

"What did you call me?" Lestrange almost suspected that he was hallucinating, Potter just called him?This classmate?

"Sorry, I just didn't remember who you are for a while? Because your appearance is so popular, it's as disappointing as your spell." James said regretfully.

Lestrange was suffocated by James' words, and his eyes widened. Potter's speaking style has always been very vulgar. When did he learn this insulting method without a single dirty word!The surrounding Griffindor students burst into warm applause, cheering for James non-stop.

"By the way, may I ask your surname?" He really didn't know, so he just wanted to ask by the way.

Lestrange was trembling with anger, he felt completely insulted by Potter!He clenched his fists tightly, as if he was about to rush forward to fight hand-to-hand with the opponent.

The class bell rang, and the professor's arrival stopped the flames of war in good time. Lestrange sat back in his seat unwillingly, and at the same time locked his gloomy eyes on James, as if he was thinking about some vicious plan .

James' performance today even the students who have never been used to him can't help but applaud him. He didn't provoke the other party in an arrogant way, nor did he insult the other party in that vulgar tone, and he didn't take the initiative. When Trange attacked him, he removed the opponent's weapon.His attitude was very natural from the beginning to the end, and he didn't raise his head and look at people with his nostrils.

"Children, you will be taking the OWLs exam in a short time, and I wish you all the best in your exam." Horace said.Slughorn is about 50 now, but he looks much younger than his age.

"Today we are going to study the content that OWLs have often been tested over the years, because it is really important. Children, prepare your eyes and ears, especially." Slughorn's deep eyes Scanning the students in the audience, he paid special attention to James for a long time.

"Especially some mischievous kids, if you want to do well in OWLs, you'd better concentrate, whether you like the delicate craft of Potions or not. Believe me, it will be good for your future."

Slughorn turned around, and lines of writing began to appear automatically on the blackboard.

"Today we are going to learn about Veritaserum, a highly crafted potion invented by the famous witch Portolemy in the early 18th century. The Folk Wizarding Association has been promoting this potion for a long time. It is used in judicial torture to replace the inhuman methods of extracting confessions by torture, dementors, and Legilimency. But in fact, because the raw materials for making Veritaserum are very precious and rare, this has not been successful so far.” Slughorn said.

"Next, let me introduce the raw materials and production methods of Veritaserum..."

White writing continued to appear on the blackboard. James picked up a pen and followed the records. As he wrote, he began to slip away.He stopped writing, turned his head secretly, and glanced at the person sitting in the corner.He was taking notes seriously, his nose was almost stuck to the paper, his writing speed was astonishingly fast, his movements were nervous, James watched intently, the more he watched, the more he couldn't help laughing with great interest. Looking at the other party's weirdly big nose, why is it still so big, and the hair is still so oily, except for the younger skin, there is almost no change.

"Mr. Potter?"

"Mr. Potter!"

Suddenly, the huge body blocked James' line of sight, he suddenly came back to his senses, and slowly raised his head, Slughorn's sullen face came into view.

"professor……"

"Mr. Potter, please allow me to guess this way, if the blackboard didn't fly to the back, then your eyes are on the back of your head?" Slughorn sarcastically smiled.

The students in the classroom snickered, and James' face turned red.

"Please take notes carefully, Mr. Potter. Being smart is not an excuse to be lazy. In fact, many people who claimed to be smart when they were young and didn't study hard will not have good results in the future." Slughorn said seriously .

"I'm very sorry." James bowed his head sincerely.

As soon as this remark came out, everyone in the classroom was startled, even Slughorn was taken aback. James said: I'm very sorry?Has he changed sex?

"Mr. Potter, please describe the ingredients of Veritaserum, which I have just described." Slughorn asked.

"Yes, Professor." James didn't flip through his notes, in fact he blurted out almost proficiently as if he had already memorized them.

"There are nine kinds of raw materials for veritaserum, namely: tail feathers of dumb birds, belladonna essential oil, aconitum, three major European poisonous snakes, unicorn horn powder, crescent grass, dragon liver, virgin virgin fragments and beetle eyes .”

The answer was spot on, and Slughorn had to say that James was really a very bright student, perhaps the smartest he'd ever met, but also the most mischievous.There are two students with good potential in the class, one is James and the other is Severus.If James could use his clever mind on potions, he might become a master of the generation, but unfortunately, the other party never seemed to be interested in this.As for Severus, he is the one that Slughorn decided to focus on training. Potions requires extraordinary talent and rigorous thinking. Although that child is not lovable, his talent in this area is beyond the reach of others. The important thing is that Severus has a very correct attitude towards learning. Slughorn likes children who are humble, hardworking and love to learn.

"Mr. Potter, for the sake of the accuracy of the answer, I will not deduct points for Griffindor. I hope you can adjust your study attitude." Slughorn turned and returned to the podium.

Having escaped the fate of deducting points, James breathed a sigh of relief, and finally glanced at the person in the corner. He didn't look up at all from the beginning to the end, just immersed in his own world, as if everything around him didn't exist , what happens has nothing to do with him.

The bell rang for the end of get out of class, James put the books and notes on the table into his schoolbag, Sirius came over and put his arms around Harry's shoulders.

"It's Quidditch training in the afternoon, hasn't James, the star who turned into a potions expert, forgotten?" Sirius was stunned by James' performance just now, and this guy actually gave the correct answer.

"Sirius, please don't hurt me anymore." James smiled helplessly.

"By the way, I can't believe you did the preview before class." Lupine touched his forehead and sighed.

"We're students, Remus. Besides, exams are coming up, and I don't want OWLs to fail." James said that the main task of students is to study, not to make jokes, although his current situation is slightly different from before.

"Let's eat first, and then let's change clothes."

James picked up his schoolbag, and several people walked away talking and laughing...

The familiar red Quidditch jersey and brown gloves were placed in front of him. There was a name tag pinned to the clothes, which read: James Potter.After I changed my clothes, I stepped on the solid ground with my feet, and a feeling of peace of mind came to my heart. James sighed, turned around and took another look at himself in the mirror.

Black hair, neatly combed, familiar outline, deep and narrow eyes with hazel pupils, wearing a pair of gold-rimmed glasses.The figure is tall and lean, and the whole body is covered with even and slender muscle lines.

Actually...he still doesn't know what happened!Yes, the series of changes that happened to James were not without reason, all because... because he is not James Potter!The matter is very complicated... There is no reason to explain it at all... The only certainty is that the soul contained in this body is Harry Potter, the son of James Potter.

Recalling what happened the day he woke up, James fell into deep thought...
