Chapter 30 third quarter

Ningzhou, deep in the ancient forest, on the top of the cliff. There is a gap in the dome made of pure copper, and the starlight pours in like a sea.It was a bright starry night indeed. The ground is also made of pure copper, and countless concentric copper rings rotate slowly, with complex and profound symbols etched on the copper rings.They are constantly rotating all the time, slowly driven by the force of the water droplets of the clepsydra, just like the huge heliograph, moon phase sphere and the Huangji Jingtian sphere surrounded by astrology.The mountain spring water that has not dried up for hundreds of years moves these instruments that mark the starry sky little by little through complex devices, and only needs to be corrected according to the correct position every few decades.

The copper circle in the center of the copper ring has a diameter of several feet and is still.The white-haired girl in the copper circle is sitting upright, moving the counting chips casually. There are countless spars inlaid on the copper circle, some are slightly bright, some are dark, and some are as bright as candlelight, but the light is cold.The girl collected the counting chips and inspected the shiny crystals one by one. "The strings of power of the stars of Beichen are about to fill up. According to calculations, in the next ten years or so, the stars of these warriors will dominate the sky. Another war is about to start? I just don't know where it will happen."

"What about Gu Xuan? Fifty years ago, you could easily calculate the orbits of the stars of Beichen. Beichen has no suspense at all for you. What about Gu Xuan? You have arranged so many calculations, but you still haven't got Gu Xuan Is it the trajectory?" The old man was lying outside the copper circle in a white robe, looking up at the sky with the pillow in his hands, and said casually. "No progress, no progress at all." The girl finally showed a disappointed expression, "When can I get the equation of Gu Xuan's seven formula joint calculation? Only then can I make up the one yuan that is missing in my current formula."

"You are too anxious." The old man laughed, "The seven equations, when you see them, you will realize that they are so simple, yet so perfect, like a perfect circle. But a perfect Madoka still has weaknesses." "weakness?" "The center of the circle is its weak point." "I don't understand." The girl shook her head. "This is the reason why I never taught you the last seven equations. When you understand what I mean when I say that the center of a circle is the weak point, those seven equations are enough to answer all your questions." The old man still smiled, "Before that, You still need to study the science of calculation and rack your brains, without going through this process, you will not understand."

"I might be dead then." "The life of an astrologer, everything is known, is the time of death." The old man said it calmly and casually. The girl stopped talking, and looked up at the sky silently in a daze.The teacher and students were silent for a long time. "I know it's there, the star that symbolizes death, but I can't catch it." The girl murmured. "Its string of power is also about to be full. For thousands of years, the twin stars of war and death are like twins, always appearing at the same time. When Gu Xuan is the strongest, the power of the star of Valkyrie is also the same. It’s so powerful.” The old man laughed, “So why don’t you try to use Beichen’s orbit to search for Gu Xuan? Although this method is not enough to make up for your missing one yuan, as long as you go through thirteen calculations, your answer can be very good. close to real results."

He said faintly: "Although it is only approaching forever, it will never really arrive..."
