Hogwarts and the Atypical Wizard

Chapter 138 Solving Monitoring Problems

Sainz's life returned to normal, and now he had an additional task, to make enough magic picture frames.

He had to make sure the frames could be used by Tom but not be noticed by the other paintings.

This is not easy.

It’s hard to say about other paintings, but after the old principals discovered them, they couldn’t help but have doubts, and after tracing the truth, it’s hard to say.

So he had to make sure the frames were small enough, so small that even if he put his eyes on them he couldn't see what was outside.

It would be best if the creatures in the "painting world" didn't notice them. Even if they did, they would just treat them as inconspicuous decorations on objects.

Tom said that the painting world also has their daily activities, and these windows are not floating in the air without support, but are hung on the wall or other objects like paintings or mirrors.

As long as Sainz's painting frame is small enough, it is not difficult for the creatures in the painting world to mistake it for a wall decoration.

The fear is that a large number of them will appear in a short period of time, attracting the attention of the school principal or the college gatekeeper, and then reporting to the wizards in reality, and the possibility of being found out will be greater.

The physical distance between picture frames cannot be measured by the distance between them in reality, because the scale of the content in each painting is not the same, which makes the "frame distance" between two paintings placed side by side much farther than it actually is.

Therefore, as long as Sainz's frames are small enough and the scale is unbalanced, the possibility of discovering regularities in the painting world for these extra frames that open into the real world is not particularly high.

This is one of them.

There is another problem, which is the field of view. The picture frame size is set at two millimeters, but the field of view cannot really be only two millimeters, otherwise Tom will not be able to see much information even if he blinds his eyes.

This problem is easy to solve. Just refer to the cat's eye design on the security door.

From one side it is a very narrow eye, but from the other side the view is very wide.

The field of vision problem has been solved, but there is still one problem that needs to be solved, which is that other characters in the painting cannot see the same field of vision.

This problem is easy to solve.

Two directions.

One direction is to refer to one-way glass. You can see the scene on one side, but you can only see darkness or other scenes on the other side.

One-way glass ensures that the painting world cannot be seen from the wizarding world.

Another direction is to refer to polarized glass. Special polarized lenses are needed to see the image. Without special equipment, you can only see the layer on the surface of the glass.

Which one to choose?

Choose? What to choose?

Of course, two together.

Single-transmission polarized glass cat's eye!

"Tom, did you get the singlet lens I prepared for you?"

"Saienz, you are a genius! How did you come up with this idea?!" Tom held up the simple conical monocular in his hand and expressed his admiration for Sainz's brilliant idea.

Sainz waved his hand to refuse the compliment. He estimated that any Muggle with a certain amount of life experience could think of this. It was not his original idea, so there was nothing to be proud of.

The mirror in Tom's hand is a reverse telescope, the small end is the objective lens, and the large end is the eyepiece.

The field of view on the surface of the picture frame is only two millimeters. You can't ask Tom to put his eyes against the wall while working. That would be too disgusting.

There is such a special telescope. He only needs to cover the small head of the mirror on the window of the painting and look through the eyepiece like using a telescope, avoiding the embarrassment of lying on the wall with his butt sticking up.

"How's it going? Is it useful?"

"Of course, of course! It's great!

If you hadn't told me there was a window here, I would never have thought there was one here.

Even though I had put my eyes on it before, I didn't see anything at all!

Really, you are right here, but I can't see you at all through that little hole!

But there is absolutely no problem looking through this mirror!"

Sainz smiled knowingly. The busy work for more than a month was not in vain. "How is the view?"

"View? ... Well, of course it's not as good as the view from a large window, but it meets your requirements."

"So, you can see the whole dormitory from this small hole?"

"Okay, there's no problem seeing your dorm."

"That's enough. At worst, we can just add a few more. How's the camouflage?"

"No problem at all. Didn't I just say that if you hadn't reminded me, I wouldn't have noticed that this inconspicuous little spot on the wall was actually a window."

"That's good!"

It's fine as long as it's hidden well in the painting world, and it's even easier to hide in the wizarding world. As long as the border of the painting is not made so flashy, such a small dot will not be conspicuous at all in this old castle.

In fact, Sainz didn't even think about putting a frame on it; the whole painting was just a small dot with a diameter of two millimeters.

Such a dull little black dot is a perfect match for a thousand-year-old stone castle. Even if it appears in a seemingly magnificent auditorium and foyer, it will not appear out of place at all and will not arouse suspicion at all.

"Thank you for your hard work, Tom. There will be a lot of trouble in the castle in the next few years. My safety is in your hands!"

Tom drew out his rapier and held it upright in front of him, "Never let any dangerous person get close to you!"

"I believe you, Tom!"

"No, I have to keep an eye on Quirrell, the bad guy!"

Tom said angrily, "Dumbledore is really crazy, how could he allow such a person to enter the castle?!"

"He probably has his considerations, Tom. There's no need to be angry. Anger can't solve any problems. It will only affect our thinking."

“I know, Sainz, I know!

I am a knight, a Griffin Knight!

I know anger can cloud my judgment, but I just can't help wanting to say something!"

“Tom, I know you care about me.

You have been here for some time, and you probably know a little about Dumbledore. I don't think Quirrell's disguise can fool him."

“That’s why I think he’s crazy!

He knew that Quirrell was a dangerous person, but he allowed him to stay in the castle with such openness! "Tom strongly disagreed with Old Dumbledore's decision.

"He has his plans, Tom, he--"

"He probably thinks he's omnipotent. Sooner or later he'll have to pay the price for his arrogance!" Tom muttered in dissatisfaction and disappeared from the picture frame.

Sainz is a bit scratching his head. When the system was originally designed, was he designed to be too intolerant?

But it was also good that with such an alert Tom watching over him, the chance of being caught off guard by Quirrell was much smaller.

Well, go on. With the mature example, it will be much easier to draw other cat's eyes through single-transmission polarized glass. It is nothing more than some mechanical work.

At present, his magic painting cannot be done without a handheld paintbrush.

When he can reach a certain level, he believes that he will be able to use magic to help him paint.

In the original storyline, after Old Deng was murdered, his portrait was hung in the principal's office the next day.

It can't be prepared in advance, right?

Focus on making surveillance...

Sainz laughed at himself in his heart, "I am so pathetic, I keep saying I want to improve my artistic skills.

In fact, only I know in my heart that the real purpose of learning magic painting is this!"
