With the foundation of 90 minor meridians, the cultivation of martial arts techniques was smooth and easy.
The difficult part was the sword!
From the way the eight stones were shattered into tiny pieces, it was clear that the sword formation had a high requirement for the sword.
An ordinary sword would become useless after one use. In fact, it could not even withstand the high-speed impact of the sword formation and was destroyed.
Therefore, the sword had to be a good sword!
In the Atlas of the "Dayan sword formation," there was a set of forging blueprints for the forging of Nirvana artifact long swords. The sword that was forged was called the Dayan sword.
Its grade was grade four, and among the required materials, the blood serpent stone happened to be one of them, and it was only an auxiliary material.
The main ingredient was a top-notch material called void dust.
Its rarity was even more precious than the sky Fire.
