Back in the Wilderness Realm.
The grading of weapons was, in general, the same as for cultivation techniques and medicinal pills.
They were divided into four levels: Heaven, Earth, Yellow, and Mortal.
Each level was further split into upper, middle, and low-grades.
But in the boundless realm, above the Heaven class, there existed a concept called spirit artifacts.
As the name suggests—
A weapon with a spirit is called a spirit artifact.
The Dark Demon Sword was originally a peak Heaven class sword, but after absorbing the wild ice sword spirit from Miss Mu's body, it evolved into a low-grade spirit artifact.
Yet, in the boundless realm, a low-grade spirit artifact is already far from sufficient.
If it weren't for Ye Qiubai's unique physique, cultivation techniques, and sword intent holding him up—
Wielding a low-grade spirit artifact like the Dark Demon Sword in a contest against cultivators of the same strength would put him at a huge disadvantage.
