Lu Jing was shaken by the contents of the jade slip.
She delved into it and found that the content had been hierarchically edited, roughly divided into four major sections: "Fundamentals of Fluid Mechanics," "Low-Speed Aerodynamics," "High-Speed Aerodynamics," and "Computational Fluid Mechanics."
The entire text covered the principles of dynamics, differential equations, fluid motion, and aerodynamic properties, among other areas of knowledge.
In the opening introduction, the author self-identified as the "Huahu Hermit," introducing the text as a guide for cultivators to design, forge, and master flying swords themselves, enabling the flying sword magic tool to become a true sidearm. The mechanics of the flying sword's operation and combat were elucidated from beginning to end.
