Xu Yi took the notebook and opened it, finding a title written on the first page.
"An introduction to the fundamentals of magical machinery"
Reading further, he found that the notebook covered the most basic, yet also the most essential, principles of magical mechanical theory.
Avita had described these fundamentals in extraordinary detail, while making them remarkably easy to understand. Even someone who had never encountered magical machinery could gain a basic understanding of how it worked from this notebook alone.
However, the contents clearly leaned toward the theory of setting up magic arrays and how using them as a power source affected magical machinery, with somewhat less coverage of mechanics.
Simply put, it was closer to an introductory reference book on magical power theory, and still fell somewhat short of a complete introduction to the fundamentals of magical machinery.
This did not surprise Xu Yi. When he had asked Avita to help compile the book, he had specifically told her to focus on setting up magic arrays and how the power they supplied affected magical machinery. He would write most of the sections on mechanics himself, with assistance from Canby and the other engineers.
Xu Yi skimmed through it and found that Avita had indeed lived up to his expectations. Not only were there no obvious errors or omissions, but she had also provided exceptionally thorough explanations and insights into many details, even exceeding what he had envisioned.
"Excellent, Avita. I've found that your grasp of magic array theory is now absolutely on par with mine, or even with that of any mage in this world."
"You're exaggerating." Avita smiled bashfully, thought for a moment, then asked, "Mr. President, do you really intend to publish this book for the public?"
"That's right." Xu Yi snapped the notebook shut. "I
