Days to grind friendship at Hogwarts

Fred and George looked at Glenn confused, as if they didn't understand what he was talking about.

"You should know what methods the Ministry of Magic uses to detect the use of magic by underage wizards, right?"

Glenn smiled and asked.

Fred recalled for a while and replied: "I heard my father say that it should be a kind of magic called "Trace Silk", which will not disappear automatically until you reach adulthood."

"Then here's the question," Glenn asked with a mysterious expression, "Do you know how trace silk works?"

"this..."

The two of them seemed to have never considered this issue, and they couldn't react for a while.

It was rare to see the twins deflated, which made Glenn feel funny.

At this time, Mrs. Weasley's call came from under the car.

"Fred! George! Where are you?"

Glenn waved his hand.

"Go quickly! I'll explain it to you when the train starts moving."

"Keep your word!"

George said nothing and quickly pulled Fred out of the car.

Glenn left Harry in the compartment and walked through the car in front, looking for Qiu.

Counting the adult wizards who came to see them off, there were nearly a thousand people crammed into the entire platform and the train, and even the cursor on the system map was connected.

Countless names overlapped so densely that it was impossible to tell who was to whom.

The carriage was noisy and crowded, and the narrow aisles were difficult to pass.

Glenn walked through the crowd, got off the carriage at the back, and finally saw Qiu who had just passed through the partition wall.

She was only accompanied by her mother. It was thought that Mr. Zhang was busy with work and could not come.

"Glenn!"

The girl looked around and noticed Glenn who had just squeezed out of the carriage. She smiled and waved.

Glenn walked over with a smile, bowed slightly, and greeted politely: "Hello, Mrs. Zhang."

"Long time no see, little Mr. Ollivander."

Her voice is elegant and her tone is soft.

"It's almost time, Mom, we should get in the car."

Qiu turned around and hugged her mother and said.

Mrs. Zhang kissed her daughter gently on the face and said, "Go and study hard at Hogwarts."

Sure enough, this is how mothers all over the world say goodbye to their children who are going to school.

The two of them walked all the way to the car where Harry was, and Glenn took Qiu's suitcase and lifted it onto the running board.

The carriage was gradually getting crowded, and it became inconvenient to use magic.

Fortunately, Glenn is quite strong and the girl's box is not too heavy.

He stepped onto the pedal, turned around and stretched out a hand to Qiu.

"Woo~"

A whistle blew, the carriage trembled slightly, and the train started slowly.

A slender hair as white as jade fell on Glenn's palm, and his hand felt warm and moist.

Holding hands with each other, Glenn used a little force to pull Qiu into the car.

The girl's face turned slightly red and soon turned fair again.

The two of them dragged the box to the box where Harry was sitting. Ron, who had a stain on his nose at some point, was already sitting opposite him.

Hermione's two useless men stood up and helped Glenn lift the suitcase to the luggage rack.

The Hogwarts Express gradually accelerated and left the station.

The compartment door was opened, and George's head poked in.

Seeing that Glenn had returned, he took Fred and sat across from him.

"Tell us quickly, Glenn! What's going on with Trace?"

They did not go to the middle car to find Lee Jordan like in the original book.

It seems that the temptation to perform magic outside of school is much greater than that of a bag spider.

Glenn felt funny in his heart.

This was the first time he had seen the Weasley twins showing such eager eyes, including the last time they pestered him to learn the Rapid Fire Charm.

"It's still the same question. Now that you know the trace silk, how does it work?"

"How it works..."

Fred repeated, lost in thought.

"Could it be a magic attached to the wand, like a flashback spell?" George asked.

Glenn shook his head: "As a semi-professional wand maker, I can tell you responsibly that there are no traces of anything on our wands."

The twins' eyes were even more blank.

When Glenn saw that they didn't talk for a long time, he stopped talking and started to explain the problem of Zongsi.

"If I want to give a definition to trace silk, I think it can be said like this - it should be regarded as a kind of magic of exploration and recording."

He looked directly at the twins and started from the theory like a teacher.

"The trace will be attached to every little wizard when he first arrives at Hogwarts. It can sense the use of magic within a certain range around him, and record and report it to the Office for the Prohibition of Abuse of Magic."

The twins were confused and waited eagerly for him to continue explaining.

Glenn smiled slightly: "Actually, it can be explained this way. This kind of magic can detect what magic has been used at a certain time and place."

"etc..."

Fred seems to have discovered Hua Dian.

George also reacted immediately: "Time, place, magic...there is no specific person who cast the spell here!"

The smile on Glenn's face became more and more obvious.

"Zongsi can determine the type of magic spell through the fluctuation of magic power. However, it cannot specifically distinguish the owner of this magic power."

"The master of magic? You mean..."

The twins had a look of surprise on their faces.

"It seems you have guessed it." Glenn winked at them, "Yes, based on traces alone, the Ministry of Magic cannot know who actually used magic in that area."

George pondered thoughtfully for a while, and then asked: "But how can those students who are found by the Ministry of Magic cast spells outside the school?"

"For this question, we can give you an example." Glenn replied: "If a young wizard of Muggle origin uses magic, and according to the records of the Ministry of Magic, there is only one underage wizard in that range, then it can be easily determined.

Who used that spell."

"Doesn't that mean that as long as there are adult wizards around us, we can use magic at will?"

Fred and George were shocked at the same time.

"That's right." Glenn nodded, "Of course, the premise is not to be caught by other people. If someone reports you, the Ministry of Magic will not care about any trace."

"Haha! How could we make such a stupid mistake?"

After learning the shocking secret, the Weasley twins immediately regained their arrogance as the Demon King.

When he heard the system prompt sound, Glenn was in a good mood.

A simple little knowledge about tracing silk, and another 2000 exchange coins were earned.

The feeling of having sex for free is so good.
