Hogwarts: I graduated before the system came

They even wondered if their own subjects could be learned in this way.

After all, memorizing basic knowledge is really important.

Douglas has not been idle these two days.

The seventh year class was supposed to be Defense Against the Dark Arts on Friday.

He summoned them in advance.

They were assigned to modify several empty classrooms according to Douglas's requirements.

All the contents of the modified version are kept confidential from students below the seventh grade.

During this period, Professor McGonagall came to inspect once.

After confirming that everything Douglas arranged was within the controllable range, he no longer cared about Douglas.

After class on Wednesday evening.

Douglas brought gifts he had prepared.

Arrived at Filch's office behind the marble steps in the hall.

As soon as I entered the door, I smelled a damp and rotten smell.

Argus Filch is the caretaker at Hogwarts.

Basically, in everyone's eyes, he is a person with a bad temper and is annoying.

But as a castle manager he is very conscientious and responsible.

He also had a cat named Mrs. Norris, which was almost his entire spiritual sustenance.

As a cat lover, Douglas could be said to be the only student that Filch could tolerate during his time at school.

Of course, all this is the result of Douglas's management.

As a modern youth who has experienced the beatings of society.

He knew very well that in many places, integrating with some grassroots people often had extraordinary effects.

So while at school, everyone took the initiative to avoid Mrs. Norris's inspections.

But he chose to look for Mrs. Norris, relying on his experience in raising cats in the Muggle world and the advantage of the Hogwarts kitchen.

Step by step, he became the only student in Hogwarts who would be treated favorably when given detention by Filch.

Even when he got lost in the castle, he would receive friendly help from Mrs. Norris as long as he consumed a piece of dried fish.

After Filch let Douglas in, he snorted coldly and said nothing.

Douglas was not embarrassed at all and opened the gift in his hand.

It was a can of catnip cream he had prepared.

He leaned towards Mrs. Norris's mouth in Filch's arms.

"Oh, Mrs. Norris, I haven't seen you for a few years. Do you still recognize me?"

Mrs. Loris sniffed it, then stuck out her tongue and licked it with enjoyment.

After seeing this scene, Filch couldn't keep a straight face:

"I thought the famous Mr. Holmes had forgotten me, a humble administrator."

Douglas took Mrs. Norris from Filch's arms and explained embarrassedly:

"How could I forget? It's just that I've been busy these past two days since I came to Hogwarts.

These gifts were prepared when they were still in the Muggle world."

Hearing Douglas say this, Filch smiled slightly.

But when he smiled, his face always looked a little weird.

"Professor McGonagall has already reminded me, because today is Professor Holmes' first day on duty inspecting the school.

So let me take Professor Holmes to familiarize himself with the patrol area first.

And a few little brats to watch out for."

It took two hours.

Douglas walked the castle patrol route again amid Filch's chattering.

And also told him a few secret passages in the castle,

Then Filch carried the cat and went on his patrol route.

Watching Filch's leaving back, Douglas smiled helplessly.

In fact, Douglas knew everything Filch said.

As a time traveler with foresight, how could he not think about the famous Marauder's Map?

As early as his second year, he had obtained the Marauder's Map from Filch's office.

It was not until he graduated that he quietly returned the Marauder's Map.

It has to be said that the Marauder's Map is a very powerful magical item.

It was not until he was about to graduate from sixth grade that he understood some of the principles of the Marauder's Map.

Then take the opportunity to remove your presence from the Marauder's Map.

This is not easy.

It's about ten o'clock in the evening.

George Weasley and Fred Weasley.

Avoid Percy who is concentrating on reading.

Carrying the will of all Gryffindor fourth-year students.

Sneaking past the Fat Lady.

Carefully walked to a corner on the eighth floor away from the principal's office.

George took out a piece of parchment from his arms and said with a sigh of relief:

"I almost showed this map just now."

Fred whispered "Lumos!" with his wand.

Then he said:

"Oh, it's all Professor Holmes' fault! Our night tour plan almost went to waste!"

George pointed his wand at the parchment and read, "I solemnly swear that I have no ill intentions!"

As soon as George Weasley finished speaking, the ink lines on the originally blank parchment began to extend, and a map of Hogwarts emerged.

And on it appeared the name of everyone in the castle.

Fred and George carefully observed everyone's position.

"Dumbledore is in the Headmaster's office!"

"Mrs. Norris is on the third floor, and Filch is on the first floor!"

"Peeves is in the abandoned women's bathroom on the second floor. Oh my god, Peeves is so powerful! We're all too scared to go into the women's bathroom!"

"My mother would beat me to death if she found out."

Chapter 25 Failure at the beginning

At this moment, George suddenly discovered something and looked carefully on the map:

"Fred, who is the professor on patrol tonight? I haven't found any professor's name on any of these patrol locations!"

Fred shook his head.

“Brother, we have been so busy lately that we forgot to pay attention!

Oh my god, we are starting to fall!"

George also had a regretful expression on his face, but then he continued to look for something on the map with a smile on his face, not caring at all.

"Ahaha, aren't we heading out?

Now let's see where our cunning Professor Holmes is.

As long as he's not in those classrooms, we have a chance to act!"

What the Weasley twins didn't know was that just a foot away from them.

In the same corner, in the shadow, there was a person standing there awkwardly.

Douglas swore that he had never intentionally used the Disillusionment Charm to spy on others.

It just happened that he wanted to revisit a place on the eighth floor.

But as soon as he arrived here, he heard two stealthy footsteps suddenly appear in the empty corridor.

Douglas swore to God that he had just reflexively cast the Disillusionment Charm and quickly hid himself in the nearest shadow.

When he realized that he was no longer a night-walking student, but a patrolling professor.

The twin brother was already in his hiding place.

It seems that as Hogwarts' top night wanderer, his vision remains the same.

Douglas was not too surprised when he saw the twins take out the Marauder's Map.

Just like the plunderer's choice, when he graduated, he also chose to leave this gift to the next students.

If not, Douglas heard the two talking about the classroom he arranged for the seventh graders.

"Oh my god, there's no Professor Holmes on the map!"

"I think he has left school!"

"Isn't that..."

"What a godsend!" George and Fred high-fived and roared excitedly.

"I guess those classrooms must be related to our practical exams!"

"We accidentally walked into the wrong classroom. Doesn't that count as peeking at the exam?"

"Oh, Fred, what are you talking about? Exam questions? We are the lost lambs!"

Hearing this, Douglas felt that as a visiting professor, it was necessary for him to give a reminder.

Just as George and Fred were about to leave, a faint voice came from beside them.

"I think you should consider explaining to me why you are still in the castle corridor at this late hour!"

George and Fred heard the familiar voice.

They looked at each other immediately, their eyes filled with surprise and fear.

But they did not admit their mistakes as Douglas had imagined.

Instead, two small balls rolled out from his sleeves and he ran towards both sides of the corridor.

When the ball lands.

Douglaston felt something was wrong, and it only took 0.01 seconds.

A beautiful silent repair spell restored the two small balls to their original state.

Looking at the two Weasleys running in separate directions, Douglas smiled contemptuously.

Humph! How dare you show off your skills in front of an expert?

Today I must let you know what is the Great and Powerful Heavenly Dragon, the Great Luo Mantra, the Prajna Buddhas, and the Prajna Bamahong.

Then he quickly added some spells to the two balls.

Then, two small balls were seen flying up quickly, flying in the direction where the two people were running.

Hogwarts was huge, and George and Weasley had a tacit understanding not to run straight back to the Gryffindor common room.

It's easy to get caught that way.
