Anna returned to her room and threw a cluster of green flames into a large wooden bucket filled with water. Soon, steam rose from the surface.

She took off her clothes and stepped into the bucket.

When the witches wanted to wash, they would ask Anna to help heat the water—after all, it was troublesome to carry hot water from the kitchen. His Highness seemed quite surprised when he learned about this, and seemed unable to accept the practice of repeatedly using bathwater.

Thinking of this, Anna found it a bit funny. People in commoner families rarely washed themselves even once a month, and reusing water was common.

He didn't even realize how much the lives of the witches he had accepted and sheltered had improved. Anna shook her head. Roland Wimbledon, His Highness, seemed knowledgeable and talented, but in some ways, he was... clumsy. From the stories she read in books, shouldn't princes participate in various banquets and social gatherings from a young age, mingling among the flowers? They could be ignorant and cowardly, but at least they should be good at socializing.

However, this feeling was unexpectedly reassuring to her.

His Highness had many astonishing knowledge in his head, such as iron machines that run on steam, and making stones float on water through calculations. And today's lesson—this world is made up of countless tiny balls, so small that they need to be magnified tens of millions of times to be seen with the naked eye. Because of this, they are everywhere, whether solid, gas, or liquid, whether human, flowers, or stones, when broken down to the end, they are basically the same.

Incredible, Anna thought, how did His Highness know these things?

After wiping her body, she dried the water droplets on her body with a fire. Putting on her clothes, she sat back at the table.

In the center of the table was the textbook written by Roland.

Taking advantage of the remaining time of Xiaohua's Illusion, Anna borrowed this textbook from Juan, wanting to read a little more before going to bed.

Starting with common phenomena in life, progressing step by step like peeling an onion, some places are also accompanied by vivid and interesting pictures. The unheard-of and novel knowledge fascinated her, and Anna found it difficult to stop after opening the first page.

However, the previous content was still relatively simple, while the latter became more and more difficult to understand. For example, the section on temperature wrote that cold and heat are both manifestations of the activity level of the small balls. The higher the energy obtained, the more active the small balls, and the hotter it looks macroscopically. If His Highness is right, then are my green flames, when magnified, also a collection of leaping small balls?

As time went by, the candle gradually burned to the bottom. The flame flickered twice and went out. At this moment, Illusion also reached its time limit. The pages and handwriting gradually became transparent and then disappeared without a trace. Darkness immediately engulfed the room until a green flame bloomed from Anna's fingertips, dispelling the night that poured into the room.

Looking at the empty table, she felt a sense of loss.

Raising her right hand, the faint green magic fire stood still on her fingertips like a firefly.

She suddenly wanted to try, if everything is made up of small balls, can it also become as small as a small ball? Anna closed her eyes, imagining it made up of countless particles.

The flame began to change.

It changed from a drop-like shape to a thin line, becoming thinner and longer, and finally like a strand of hair.

Anna felt this change. It was far from enough, she thought. Hair is still much larger than a small ball. It can become even thinner.

Although she thought so in her heart, the green flame seemed to have difficulty changing further. The light of the flame dimmed, and the slender green light trembled.

Perhaps it can't be accumulated, but connected in series... His Highness said that there are chains that fix each other between the small balls, perhaps I should reshape its form.

The particle flame in Anna's mind shook twice and was scattered with a bang. They were no longer closely connected, but scattered like stars. The slender green flame also disappeared, but in her consciousness, the flame still existed, but it no longer had its original appearance—in the deep and boundless darkness, after most of the stars fell, a small part of the remaining stars were slowly regrouping, one by one in a long line, finally forming

a thin strand composed of starlight.

Temperature is the level of activity, she thought.

As soon as the thought came to her, the line swayed, as if someone pinched one of its corners and shook it gently. After this shake, the swaying and undulation of the thin thread could no longer be stopped, and ripples rippled along it.

Her world was like ripples, and there were no longer clear outlines between things. They cheered with this wave. The magic was the same, she even felt that the one who stretched out her finger and plucked the first ripple was magic itself.

She opened her eyes, and everything returned to calm. The green flame was gone. After her eyes adjusted to the darkness of the room, the table, wardrobe, candlestick... the furnishings in the room appeared from the shadows one by one. Pale blue moonlight spilled on the floor through the window, reflecting small pieces of gray and white. Everything looked the same as usual, without any change.

But in her eyes, the world had become completely different. A black thin thread floated in the air—Anna knew that it was not really "seen", but came from her own perception.

She reached out from under the table and took out a practice iron ingot and placed it in front of her.

The black thread followed her will, entangled the iron ingot, and then quickly contracted. Like a hot knife cutting butter, the fine thread embedded itself in the iron ingot with ease. Under Anna's will, the high temperature generated by this thread was several times stronger than the green flame, but it was confined to an extremely narrow range. The iron ingot soon broke into two pieces. She picked up half of it and saw that the cut surface was smooth and flat, and she could still feel a slight warmth when she touched it.

Then she stood the iron ingot up, let the black thread stand on top, and then separated a lying thin thread, perpendicular to it.

This was the mathematical knowledge His Highness taught, taking a point as the center, and wrapping a tight line around the center, you can draw a precise circle. The area of the circle is equal to the length of the line multiplied by itself and then multiplied by a fixed constant.

Anna controlled the end of the horizontal thin thread to bend a right angle downwards, passing through the iron ingot to the tabletop. Then let it rotate gently around the center black line—compared to the previous overall changes that could only adjust the shape or temperature of the green flame, these black flames composed of particles could not only be transformed into any shape, but also the temperature of each part could be controlled separately.

After rotating a circle, a standard cylinder was cut into shape.

Because the joint was too tight, Anna used a lot of effort to knock it out of the iron block. Like the previous section, the entire outer wall of the iron cylinder was extremely smooth. Under the moonlight, she could even faintly see her elongated face on it.
