The grade of the mark can only be one level higher than the carrier it is on, the talisman, at most.
And right now, these two items are perfectly in line with the basic theorems; the mark on the small sword is purple, while the talisman is blue.
As the tip of the small sword punctured through the opening of the talisman and was inserted from below, filling it completely, all the runes inside the talisman began to tremble on their own, wrapping around the sword's blade.
In just a short while, the latter reached its limit with a rustle, bursting open and transforming into one writhing spell after another, taking the place of the original runes entirely.
This originally bright blue and translucent talisman had now completely merged, becoming a Curse Seal enveloped in purple mist.
This small palm-sized object, rectangular and like a small wooden tablet, was precisely a First Rank "Martial Artist" Curse Seal, of the Flawless Level.
