Metaphysics is the tool, and metaphysics is the way!
Only when the physical sword energy is combined with the metaphysical sword intention can the heaven and earth be united!
There are three categories and four realms of sword energy!
The three categories are ancient sword energy, also known as ordinary sword energy, enchanted sword energy and special sword energy.
The four realms are no entry, heaven and man, heaven and earth, and the realm of saints.
The sword intention has four directions and four realms.
The four directions are summarized as perception, suppression, materialization, and detachment.
The four realms are nameless, named, freehand, and transformation.
