"Master Quilakiri?" The hunter was obviously surprised. "You have clearly obtained immortal life, but why... have become so old."

"Someone has rewritten prophecies with knowledge that I have never understood and power that I have never understood. This is the first time in a thousand years. I have tried my best to understand, but I still cannot."

Quelakili sighed deeply. He thought of getting up, but his hair and beard had been stuck by layers of dust on the ground. With a painful hissing, he forced himself to stand up, and half of his hair was torn off, and strands of blood were oozing out of the torn pores; the other half of his hair pulled up pieces of sticky dust, looking filthy.

But he ignored his body at all, walked staggeringly to Ella, looking up and down with his slightly bloodshot eyes. The look made Ella a little scared, and she couldn't help but say:

"That, Master Quilakiri..."

"You have obviously guessed my identity." Quelakiry interrupted Ella, "My real name is Crodith, an apostle of the Tianfang Empire."

Ella sighed and closed her eyes. When she opened her eyes again, there was a little more sternness in her eyes.

"So, what do you want to do when you invite me here? Your Apostle of the Tianfang Empire?"

"No need to be nervous. The Tianfang Empire has not ordered me to do anything now. I invite you to come, just want to do some academic exchanges."

“Academic?”

Crodis's eyes were a little tired and a little longing: "I know what you are doing. In today's world, I can only understand what you are doing. Show me the rules you set for the sky."

He raised his hand, and the sun, moon and stars pulled the darkness away and jumped into the air; he moved his wrists and the celestial balls began to slowly rotate along their own tracks. The entire sky was harmoniously running in a hidden and real law, emitting a unique and daunting beauty.

"I don't know how many people fear this sky, and worship the sun, moon and stars in the sky as gods that overwhelm them; but there are also many people who are ambitious and use the body of mortals to guess the will of heaven; and even more, they even dare to set laws for the sky." Crodis said, "Son of Prophecy, do you know whose laws followed in the movement of these celestial bodies?"

Ella nodded.

"This law originated from Aristotle, perfected Ptolemy, and was both scholars of the Seven Hills Empire. It perfectly explained the movement of stars and put mathematical reins on the position of celestial bodies - at least at that time."

"Yes. It was only so. It was almost a thousand years, just as Ptolemy surpassed Aristotle, now it was time for someone to surpass Ptolemy." Crodis said, "Young man, now, let me see your achievements."

"I created the Eye of Hermes, increasing the accuracy of observing astral bodies. With this accuracy, there were some errors in the Ptolemy's system. However, this does not affect the practicality of this system. As long as the existing dozens of this and average wheels are added to correct the problem."

Ela followed Crodisius's appearance and turned her wrist towards the sky to correct the trajectory of the sun, moon and stars. As Ela added one equal wheel after another, the trajectory of the sun, moon and stars gradually approached the results of Ella's observation. However, this is a long and complicated process. Every time a new equal wheel is added, the movement of the celestial bodies becomes more complicated. In order to make the stars run according to the new rules, a layer of fine sweat has emerged on Ella's forehead.

Time ran slowly, and Ella tried hard to double the number of the original average wheels. Just as she wanted to continue adding a new average wheel, Crodis suddenly waved his hand impatiently, and the sun and the moon were gone, and the darkness enveloped the stars again.

Ella was suddenly woken up from her obsessed dream, looking at Crodisius in horror.

"You should know why I interrupted you." Crodis said meaningfully, "Or, you don't know yet?"

“Because…too complicated?”

"Yes. You are indeed a good mathematician. But I don't have time to continue watching your mathematical trick. With your addition, the complexity of the stars has exceeded the range that human power can calculate. Not everyone is like you, the son of prophecy."

Crodis sighed deeply.

"Son of Prophecy, there is one thing I can't understand. Why do everyone, including you, be obsessed with putting the earth at the center of the universe? The Tianfang Empire believes that God created the world and allowed the sun and the moon to rotate around the earth, but you should not have any reason to stick to the center of the earth. Look at Aztlan, they regard the sun as the main god, and believe that the destruction of the sun will bring about the demise of the world. Why can such an important celestial body not replace the earth and become the center of the universe?"

With this sentence alone, Ella realized that the one who stood in front of her now is indeed one of the greatest astronomers in the world today.

"Sure enough, there is no mediocre person who can become an apostle." Ella replied seriously, "In fact, I did consider what you said. Moreover, new calculations have been performed with the Sun as the center."

"You've calculated it?"

"I've calculated it, and I've found that if I'm centered on the sun, the whole system will suddenly become very simple."

"Then why didn't you show me your new model just now? And to make such complicated corrections on the old Ptolemy guy's model?"

"Because the movement of the celestial sphere is a real physical phenomenon, rather than a pursuit of concise mathematical model. If the sun is centered, three difficult-to-explain phenomena will appear."

Ella digs a piece of dirt from the ground.

"Look at this soil, which is made up of living things, and there are rocks under the soil, which will gradually turn into mud and sand if exposed to the wind. Everything on the earth, including the earth itself, is experiencing birth, old age, sickness, death, withering, and decay, and any celestial body is eternal. Look at the moon, pure white and flawless, and it sprinkles light on the entire earth. How can the incomplete earth rotate around the same perfect sun like these perfect stars? It is disharmonious to compare the earth and the stars, and this is one of them."

Ella picked up a piece of soil from the ground again, turned her body and threw the soil away far away.

"The rotating object will generate force like this, throwing the objects above out. If the earth really rotates around the sun, then according to my calculations, the speed will be more than 3,600 times that of the running horse. Such a fast rotation speed is enough to collapse the structure of the earth itself, throw the soil and rocks out, and let the earth fall apart. But you see, the earth still exists firmly, and we are still standing firmly on the earth. If nothing pulls us on the earth, how is this possible? This is the second."

Ella dug out mud from the ground for the third time, stretched out her arms and loosened her hands, and the mud fell to her feet.

"If the earth was moving forward rapidly, when the mud block left my palm, it had already sped forward for dozens of kilometers, but you see, the falling mud block just fell below my palm. This is the third one. These three points are enough to illustrate the absurdity of the heliocentric theory."

Wait a moment.
