Despite 'only' being a Sky grade Physique, the Prime Unity Sword Physique was highly regarded as one of the best Physiques for aspiring sword cultivators.
The Prime Unity Sword Physique bestowed upon its bearer a natural talent for the sword.
Not only that, but they'd be able to easily learn every sword technique they came across and combine them to form the ultimate Sword Art.
However, there is a downside to this Physique. As one improves in the way of the sword, they gradually begin to lose their emotions until the sword is the only existence in their heart, and they become one with the sword.
And the only way to counter this downside was to find a Dao companion to keep them from straying too far.
Alex always thought Talia would be the one to do so and planned his entire cultivation journey around them being together. Unfortunately, that would no longer be the case. So in light of that, he now put his all into mastering the sword.
