Jiang Yuebai quickly composed herself and accepted the scroll handed over by Lii Jiuchuan.
The original edition of the "Great Derivation Scripture" is stored on the top floor of the Heavenly Interence Sect's library. These two scrolls, upper and lower, were later transcribed by the Supreme Elder.
Jiang Yuebai opened the scroll to examine it, while Lii Jiuchuan gave a brief explanation beside her.
"Strictly speaking, 'Great Derivation Scripture' is not a cultivation technique. It focuses more on the Heaven and Earth Laws. The so-called Great Derivation involves understanding the changes of heaven and earth, using calculative arts to deduce everything between heaven and earth, encompassing all things."
