Sword God Shatters the Void

From the age of twelve, I held bamboo wood in my hands and trained day and night, yet I did not know what a sword was.

By the age of eighteen, I held a sharp sword, its edge exposed, and only then did I know that a sword is a weapon of slaughter.

At twenty-two in those years, I held a Hidden Edge Sword and did not rely on its sharpness to injure enemies, and I first felt the profundity of the sword path!

...

At forty, I understood sword principles and grasped its essence, seeming to have reached the peak of the sword.

Looking up at the blue sky, the sky has no form, and sword intent has no form either. If I strike with all my strength, can I break it with a single sword?
