章 4172: One Sword to Form a Country

The moment Jian Wushuang opened his eyes, the darkness that covered hundreds of miles shattered with a bang!

"One sword to form a country! The kingdom of eternal night!"

A black light flashed across Jian Wushuang's eyes!

After seven years, with the help of the remaining energy of the Nine-Leaf Sword Grass, he finally comprehended the first sword super power of the Tarot sword codex, eternal night!

The stroke had far surpassed the level of a super power and even subverted Jian Wushuang's understanding of sword principle!

Jian Wushuang had never imagined that sword principle could be used in such a way.

How was this sword a Divine Art? It was clearly the use and improvement of the divine kingdom of one thought, which could only be comprehended by Supreme martial artists, on the sword dao!
