Round Ball's voice caused Wang Teng to regain his senses.
Sword spirit!
He knew what this was.
As a grandmaster blacksmith, it was impossible for him not to know what a sword spirit was. He had just been momentarily stunned by the appearance of the shadowy serpent and hadn't immediately recognized it.
The so-called sword spirit was essentially one kind of artifact spirit.
Artifact spirit was a general term for the "spirits" found in all types of weapons.
A sword spirit was, in essence, the spirit of a sword.
It was quite evident that the Dark Shadow Sword before him had given birth to an artifact spirit.
As Round Ball had said, this semi-divine weapon's artifact spirit was complete and possessed considerable intelligence, which was a rare occurrence.
Generally, once a weapon reached the eternal level, it could give birth to a spirit.
