The Old National Teacher smiled slightly. "Little friend, feel free to speak your mind."
"Allow this junior to examine the Star Chart closely."
Song Changsheng steadied his mind and slowly walked along the direction in which the Starlight River extended, carefully observing the trajectories of the stars.
He did not know much about the ancient and mysterious art of stargazing; most of his knowledge remained on paper. Still, he had some understanding of Star Charts.
There was only a one-character difference between a Star Chart and a map, yet the technical complexity of the two was worlds apart. There were countless stars in the heavens, each with its own unique trajectory. Their brightness, position, and other aspects changed drastically with the seasons.
To observe the stars through a Star Chart required an outrageously high degree of accuracy. The more stars recorded on the Star Chart and the more closely their trajectories matched reality, the more accurate the art of observing heavenly secrets became.
To draw such a Star Chart was something only one with Great Divine Ability could accomplish. One had to observe Above the Nine Heavens year after year to discover those dim stars hidden in the depths of the Starlight River.
Thus, drawing a usable Star Chart often took hundreds, or even thousands, of years.

It recorded three hundred and sixty-five primary stars, fourteen thousand eight hundred auxiliary stars, and hundreds of thousands of nameless stars of varying brightness, some of which could not even be seen directly. In terms of quantity, it had done its utmost, but the
