They were: Black Metal, Red Firmament, Great Riverbank, Purity, Inherited Shadow, and the Seven Stars Dragon Abyss.
Each of them was a world-famous sword.
Currently, there were only two first-grade Supreme Swords in the Sword Pool Palace. One was the Supreme Sword Inherited Shadow hanging from the old Sword Sage's waist.
The other was the Seven Stars Dragon Abyss guarded by the Sword Pool Lake!
Black Metal, Red Firmament, Great Riverbank, and Purity had long since disappeared, and it was difficult to find them.
These first-grade Supreme Swords were all ancient swords. In the past 2,000 years, the highest-grade sword forged by the swordsmiths of the Sword Pool Lake was only a first-grade sword.
Although a first-grade Supreme Sword could not compare to supreme treasures like the Literary Monument, Martial Chief Stone, and Sword Bell, it was already the limit of the first-grade!
