Other techniques included "Dual-element Immortal Sword," "Split Light Sword Formation," and "Twelve Heavenly Destroyer Swords"...
These were all Sword Formation Techniques, emphasizing the coordination of forming a sword formation with multiple Life-bound Swords.
Of course, it's not to say that one must practice with Multiple Swords to study Sword Formation Techniques, because there is a type of Sword Artifact known as a Split Sword, where one sword is actually composed of several, dozens, or even hundreds of smaller swords.
If one uses such a Sword Artifact as their Life-bound Sword, cultivating one equates to cultivating dozens of Life-bound Swords.
However, the drawback of this type of Life-bound Sword is also very obvious.
If one sword can be split into ten smaller swords, it means that its power is diluted into ten parts, naturally making it extremely insufficient!
