Ella lay quietly on the broken ground, staring at the void with nothing. Her mission had been completed, and she didn't know where she was going.

As time went by, her spirit body recovered more and more intact. She remembered the ancient church of Abraham, the Orthodox church of Abraham, the radish bill and the pants bill of the Count of France, the trade in the federal government of Almany, the King of Sweden - and then, the thought of herself as Barcelona.

As the consciousness gradually becomes clearer, everything you see after Yogibe becomes more and more like a dream.

Gradually, the earth, mountains, rivers and rivers appeared in this empty world. A full moon hung in the sky, and many stars were running beside it.

Suddenly, a voice rang in her ear:

"Why are you still lying here? Everyone has been waiting for you for a long time."

Ella stood up in confusion. She saw a middle-aged man wearing a robe with a dense beard like a philosopher and a pair of bright eyes.

"Who are you?" Ella asked.

The man replied, "My name is Apollonios."

Apollonios, a great mathematician who was in the same era as Archimedes. His book "The Theory of Conic Curves" was the first to give names such as parabolas, ellipses, and hyperbolas in the book, and completely retracted the properties of these conic curves.

"Apollonios? Didn't you already...a spirit that floats in the world? Or is this the kingdom of heaven after the soul dies?"

"All of them are. Yi is not... Let's go, everyone has really been waiting for you for a long time."

After saying that, he turned around and left. Ella walked a few steps and caught up with him and asked, "Where are we going?"

Apollonios pointed to a mountain in the distance: "There."

"What mountain is that?"

"That is the mountain of mathematics, which leads directly to the throne of the god in heaven."

"The throne leading to the heaven? But we are in the seventh heaven?"

"Yes. Not. Remember: 'Everything is shaped by the mind. It is like this in heaven and the world.' Mountains are mountains that only you can see, and I am me that only you can see."

"All things are shaped by the mind?"

Ella repeated this sentence several times, but still didn't understand.

They crossed a grassland, a desert, a swamp, and a few rivers. As they were about to reach the foot of the mountain, an abyss blocked them.

"This is the road broken?"

"There was no such mountain in the world, but it was man who created this mountain. There was no such road to this mountain in the world, but it was man who created this mountain."

"Man creates a way?"

Apollonios signaled Ella to look carefully at the abyss—there were two iron chains that led to the north and south sides of the mountain.

"Pythagoras created the road on the left, called number, and Euclid created the road on the right, called geometry. Since then, all mathematicians have relied on these two iron ropes to touch the mountain of mathematics. Remember, the road chosen is different, and the scenery along the road will also be different."

Ella nodded: "I understand."

She walked to the two iron chains, looked left, then right, and finally stared at the gap between the two iron chains.

"Since the road is created by people, I will create the middle one, its name is - analytical geometry."

As her voice fell, a series of wooden boards were set up between two iron chains and a bridge was built.

Apollonios nodded with satisfaction: Very well, the third way has indeed appeared. My mission has ended here. Step forward, and a coronation ceremony will be held for you."

Crossing the wooden bridge, Ella met another man. He was also wearing a toga robe and holding a gorgeous cloak in his hand.

"Climber, you are about to step into the pinnacle of human wisdom. Put on this cloak."

Before Ella could react, he had already put his cloak on Ella and tied the buckle on her chest.

"Remember, from now on, everything you step on is number. It is the essence of all things, the mother of the gods, and the origin of universality. Its nature will prevent people from exploring Him, but there are many footprints left on the mountain, and with them, you can move forward safely."

Ella took a few steps forward, suddenly remembered something, turned around and asked, "Who are you?"

"Pythagoras."

"Pythagoras?" Ella was shocked, "Aren't you the leader of the Pythagoras school... why are you at the foot of the mountain?"

Pythagoras closed his eyes and sighed helplessly: "I can't continue to move forward because I am afraid of it deep in my heart. You go up the mountain alone, and there are two people waiting for you on the mountain."

Ella thanked her and continued to climb up. At first, the ground was covered with footprints, but as the height increased, the footprints became more and more sparse. When she came to the hillside, there was a thick mist in front of her.

The third mathematician was waiting for him on the mountain. He held a scepter in his hand. When Ella arrived, he owed and said, "I am Euclid, the father of geometry. There are heavy fogs ahead. If you want to continue climbing up, you have to find a way by yourself, but it seems that you have found a way to solve these fogs."

Ella nodded: "My intuition in geometry is not as good as my master Gotfried. That's why I found my stupid method. Using axes and functional formulas, geometry problems are just more complex mathematical problems."

Euclid nodded and handed the scepter to Ella.

"Continue to climb up. There is a warrior trying to control the infinite and waiting for you for a thousand years."

Ella wore a cloak and held a scepter and continued to climb upwards. The temperature was getting lower and lower, and finally, snow even accumulated on the road.

As Euclid said, an old man stood there with a crown. Perhaps because he had been waiting for too long, his hair, beard, and shoulders were covered with snow.

Ella had seen the old man in the portrait. She shouted in an excited voice that was about to cry, "Archimedes? Is it you?"

Hearing Ella's voice, Archimedes shook off the snow on his body, and said in an excited voice that was trembling: "Finally... it's been a thousand years, and someone has finally come here. Child, you have mastered the infinite, right? Come, come, child, you have taken off the crown of mathematics, let me crown you!"

The crown was inlaid with a huge pearl, which was more dazzling than the crown worn by Ella in the Seven Hills Empire. Archimedes put the crown on her head under the ground. At the same time, he chanted gently in Ella's ear:

"Remember, you are still just a mortal."

The coronation was over. Archimedes pointed to the higher part of the mountain and said to Ella: "Go up. Although you still cannot reach its peak, there is a throne above it for you!"

Ella took a few steps upwards and suddenly turned around and asked, "Archimedes, do you know magic?"

Archimedes was stunned for a moment: "Yes, why should I ask this?"

“∫ₐᵇf(x)dx=F(b)-F(a)”

Ella tried to read this formula. Nothing happened. It turned out that everything before was just the illusion that her spirit body saw under the influence of Jogipel, and it was no different from dreams.

Although I had expected it, at that moment, Ella's face still showed a look of crying.

"Sure enough... I am the only one who can't do magic."

She lowered her head and took the crown off her head.

Seeing this, Archimedes shook his head.

"Child," he said, "do you know when I learned magic?"

"When I first came to adulthood, or earlier?"

"It was when I realized my powerlessness and bowed down to the infinite."

Ella raised her head in surprise. Archimedes smiled and stretched out his rough hand to touch Ella's head, like touching his own child.

"Child...I hope you never learn magic."

"But...but magic..."

Archimedes gently pressed Ella's mouth with an index finger.

"Child, do you think people who can use magic are very powerful, right?"

Ella pecked her head unwillingly.

Archimedes laughed again.
