Sitting at his desk, the pen in Luke's hand, with the cap on it, tapping lightly on the tabletop.

There was a piece of paper in front of him, an envelope, and a postage stamp.

He used a quill pen, but he still carried a pen with him in his room. There were also a few ballpoint pens on the table.

Although these Muggle-related items are not prohibited at Hogwarts, they will be laughed at if they are used in ordinary times. Fortunately, Luke's treatment is special, and when he is assigned to the dormitory, it is a single room. Not only spacious, but also privacy.

With his tongue against the roof of his mouth, Luke frowned with a thoughtful expression.

During today's class, Beth Richie's words and attitude surprised him a little. But this is not the point, after all, the strength of the Liqi family is not weak, and if you are attached to the Nott family, you want to climb up, and you can climb up if you are attached to yourself.

Strictly speaking, his current power cannot be compared with the Nott family, which still has a large amount of land. When it comes to money alone, there's no comparison. Although Luke is rich, he only has an old uninhabitable mansion and a wooden house in the woods.

Other than that, all that was left was the inheritance that the Reims family had given away at that time.

But the problem is that all those properties were also handed over to Gemma by Luke. When Gemma can grasp everything in one hand, she will divide these properties to the people below to take care of.

Luke had too few people to trust.

The people of the older twenty-eight families who had a good relationship with him did not really follow him. That's why Luke has almost given up on recruiting people from the fourth grade and above, and the fourth and third grades are just merit-based friends.

Everyone has a good future, and there is no need to take this risk with you.

In other words, Luke's authority is not important in their eyes. It's just a child.

However, the Liqi family is not a deep-rooted twenty-eight family after all. You must know that after the extinction of the Gaunt family, since Luke was reborn, he has deeply felt the preferential treatment that the Gaunt family will receive in the wizarding world.

This is more than a decade after the Gaunt family disappeared. Even Marvolo Gaunt, who was mixed with that virtue, was still a figure with a head and a face in the wizarding world, and ordinary people didn't dare to pit him.

And what the Liqi family said was good was called upstart, but what was not said was good, in the eyes of the twenty-eight families, they were a group of nouveau riche who wanted to climb down the pole. They wanted to borrow the east wind of the Nott family, and the Nott family also thought about whether they could wipe the Richie family dry.

Even, the Liqi family may still be at a disadvantage in the struggle. Otherwise, Beth Richie would not have courted herself for no reason.

Of course, it didn't matter, what really made Luke babble was Dumbledore standing in the doorway waiting for him when he walked out of the classroom.

"What are you bothering about?"

Dumbledore asked, curious.

Without waiting for Luke to speak, Dumbledore continued, "What are the students not doing well? Makes you dissatisfied?"

Luke pondered for a moment, then shook his head, then smiled suddenly, and said helplessly, "What are you talking about, Professor! I just couldn't figure out what some people were up to for a moment."

Dumbledore looked at Luke's smiling face and didn't say anything, just patted Luke on the shoulder and said, "If you don't want to say it, forget it, but ...... Don't get too upset, think of a solution, if you really can't find it, come and discuss it with me, it's not bad to discuss it with Minerva."

After saying that, he didn't care what Luke's reaction was, and turned to leave. Obviously, there is no intention to get to the bottom of it.

Looking at Dumbledore's back, Luke's facial features were almost wrinkled.

If he had been guarding against Luke like a thief as before, Luke would have felt a little more at ease. Now, close and friendly, Luke didn't know what to do for a while.

Luke, who has always eaten soft rather than hard, is really unwilling to hurt people who are really good to him and care about him.

Those should not have been harmonious

The people who get along, he would rather offend to death, and it is best to fight when they meet. After all, Luke didn't have to be burdened when he started.

Now, Dumbledore had become the kind of person who trusted him. So if he betrayed Dumbledore's trust in him again, he would feel very embarrassed in his own heart.

Of course, there will be no big mistakes. In the face of real events, these emotions can be restrained......

But it's just restraint.

"Pretty sharp eyes......

Luke muttered softly.

He didn't expect that he was cracking the flash blast, but the people below didn't react, and the trace of disappointment was seen by Dumbledore.

It can only be said that Dumbledore is indeed powerful.

Even now, Luke, who is sitting in a chair, still feels a little helpless when he thinks of the students' reactions.

How could he not be disappointed.

Mirrors, of course, can't reflect all the light, let alone other spells. The enchantment thing, it just looks like a beam. In fact, it is a special form of transformation of magic. But the flash shock really does turn magic into a beam of light.

And easily resist with a mirror, this is physics.

But...... How could he not be disappointed when he was surprised by the "basic principles" of such a basic physical phenomenon, but no one took over it.

"It's too much to underestimate Muggles......

Luke shook his head and said with emotion.

The ruler is long, and the inch is short. Luke knew very well that this kind of thing could not be said alone, or that flash of shock to say things. When he found it in his own pile of spellbooks, Luke was amused.

This spell is very strong, both in terms of the speed of the start and the power, it is very strong. It can even penetrate the magic barrier with half the effort.

But...... Just a mirror is enough to stop this powerful spell. The spell that was recorded in the spell book was so time-consuming and laborious to learn seemed so redundant in front of a small mirror.

Combining physics, or any other discipline with magic, is sure to produce some special effects.

But for now, the scientists of the Muggle world need to be said. The vast majority of them have no knowledge of the wizarding world. Even if some of them may have heard about it from the people above, those *** in the Muggle world are all ignorant of the wizarding world, let alone the scientists below them.

And the students of the wizarding world ...... Muggle studies classes are not reliable. Professor Keriddy Bubbaji was a pro-Muggle wizard who spent his days in Muggle studies classes promoting that wizards were no different from Muggles. But the students scoffed at it, even Luke. He didn't know why two Muggles could give birth to a little wizard. But the gap between wizards and Muggles could not be more than a world apart.

To say that it is no different is a bit too far from objective reality.

And even more puzzling is that Professor Bubaji ...... He's a pure-blood. Although he is not a nobleman, he is really a pureblood.

The forest is big, and there are all kinds of birds. Luke himself has no position to say that Professor Bubhaji is wrong.

Moreover, Professor Bubbaji's understanding of Muggles is also relatively backward and superficial. With a bit of condescending speculation.

This made Luke really helpless. Judging from the performance of the students in the previous classes, even those young wizards who came from Muggle families have a lack of understanding of the study of physics. It stands to reason that they shouldn't be unaware of the truth of reflexes, but none of them said that they might not be aware of it, or they might not want to make themselves appear out of place.

The superiority of the divisions lasted for thousands of years. Since their birth, they have been stronger than humans. Not in the most ancient periods.

A thousand years ago, even a normal adult wizard could fight a witch hunter in a squad of the Holy See.

And now, wands have the benefits of wands, and guns have the power of guns.

And, in fact, the offensive and defensive forces have changed. The shadow of the nuclear level is not only over the head of the Muggle world, but also over the head of the wizarding world.

Of course, to be precise, it was over Luke's head alone. After all, everyone else...... I'm afraid that not many people really know what this thing is.

"Thinking too far. It's good to deal with the immediate worries first."

Luke himself knew that it was not fun, and in the process of his own actions, he had to bring as few Muggle things as possible. Even after Hermione developed the formula for the spell, she had to erase some of the "scientific" elements in it and paint it with the color of "magic" to whitewash it.

This is a must-do. The contradictions between the new nobility and the old nobility, between pure-bloods and half-bloods and Muggle wizards, between wizarding and Muggle worlds, these are all three things that are very fatal. And if the two contradictions are mixed together, it can only be said that ...... The big one is coming!

You can't do that, Luke knows it.

Pulling out his pen, Luke lay down on his desk and began to write on the letterhead.

「…… Everything is fine here, and I drink the milk before bed, so you don't have to worry about it...... I just don't know how you're doing now, the last time I saw you, I was only eight years old......

The whole article is full of words that are not nutritious and have no purpose. It's like a casual chatter without a match, and it's like a coquettish without a mouthful.

"I never let anyone else know about your existence. If it weren't for the postcards you send me every year, I would have wondered if something had happened to you."

At the time of writing, Luke's face was visibly helpless.

"I did a lot of things after I went to school. Made a lot of friends. My friends are sincere, but it's a pity that my work is still a little rough. Voldemort was a great target, and I set it up for my own good. With such an enemy, some people's eyes will not be on me......

「…… I really don't know where you are now, so I can only hit this letter to the address you used to last invent a postcard for me. You should at least tell me next time where your next stop is."

"Anyway, I have no problem with you wandering the Muggle world, but I need the help of my family now, and if you don't have an opinion, I'll send you a letter directly......

After writing, Luke looked at the letter, in addition to the smooth sentence, it can be regarded as a feeling, the preface does not match the afterword, the previous sentence is still talking about the front door building, and the next sentence has become a hip shaft.

At the same time, the handwriting is far more fluid and free than what Luke used to be. Apparently quite relaxed when writing. The expression on his face looked quite helpless, but in fact it looked like he was three points dependent.

This meant that no one else who knew Luke was present. Otherwise, you will be surprised.

Self-reliant and self-reliant, there is no doubt about calculation, when did the mature and steady Luke have such a look.

Luke is well aware that eggs can't be put in one basket. Nor can one just rely on one side. The Reims family is not reliable, but now they have to rely on it. The Kane family came strangely and took the initiative to send it to the door, which seemed to have no malicious intent, but Luke always had a little guard in his heart. Gemma is of course her own person, but it is also a fact that she is strong and weak.

It's nothing for the Lance family to be honest and obedient, but once they want to make trouble, Gemma can barely suppress it, and it is already extraordinary.

It's more likely that she will have to suffer herself.

Seeing that things were on the right track, Luke knew more and more that he should take precautions with his back hand.

The actions of the Richie family made him feel a little uncomfortable. So it's better to prepare in advance.

Once the letter was written, Luke packed it into an envelope with a silver serpent on a green background. After writing, I glanced at the warm fire paint,

He picked up a silver knife on the table, made a slight cut on the tip of his finger, and the blood fell into the fire paint, which first turned red, and then returned to its original color.

After Luke sealed the envelope, he affixed the envelope with the stamp depicting the Eiffel Tower.

When he was done, Luke threw the letter into a small mailbox at hand.

The letter will then appear in a mailbox on a street in England, where it will soon be picked up and delivered to the address that has already been written.

However, whether there is a recipient at that address, Luke himself is not sure.

Although it was written with a pen, it didn't mean that Luke didn't do it. A simple spell goes down, with a special fire paint and Luke's blood. No one will be able to open the letter except for a certified person. Even if you open it, the handwriting on the letter will quickly disappear.

It was an irreversible spell, and Luke was confident that even Dumbledore would never be able to break it by force.

Leaning back in his chair, Luke looked calm, but there seemed to be three points of remembrance in his eyes.
