After she finished reading Imperial Beast Art, she realized that the methods were actually not difficult. She didn't know how they could have possibly gotten lost over time.
The book ended with one sentence, that the rank of beasts that could be tamed were dependent on her mental power. The higher the rank of the Spirit Beast, the stronger one's mental power would have to be. This was a point similar to alchemy.
"Sigh, looks like I have to increase my mental strength first!"
Sima You Yue sighed. Initially, she thought that cultivating Spiritual Qi was the most important, who would have thought that the art of Beast Taming and cultivating Spiritual Qi were just as important as each other.
She put down the Imperial Art of Beast Taming and came in front of the Secrets of Soul Cultivation and took down the book. The shining light that had suffused the book dissipated, letting her see the entirety of the book.
