The civilization of mankind did not leap to its current achievements overnight, and similarly, the towering mountain of Sword Dao did not spring up out of thin air with the forging of the first sword.
The sword, an ancient and eternal weapon, has been persistently studied by humans over thousands of years. It seems to possess infinite potential, such that even after its development by millions of people over a span of thousands of years, it continues to create unprecedented miracles from time to time.
The "General theory of six dynasty sword art", as its title suggests, traces the development of the Sword Dao from the Xia dynasty, through the Shang, Zhou, Qin, Han, and Jin dynasties. It elegantly summarises the main points without focusing on trivialities, providing a grand and clear exposition.
