Ultimately, not even a small half of the rust on the Hidden Edge Sword fell away.
Shen Feng merely stimulated about seven percent of the Hidden Edge Sword's power, and with the enhancement of his own strength, he was more than capable of dealing with Jiang Muyun before him.
Where the rust had fallen off, an impossibly deep black was revealed.
The Hidden Edge Sword was a very unique Immortal Artifact, undetectable in its powerfulness to others most of the time.
Even during the process of attacking with the Hidden Edge Sword, the enemy still could not perceive the terrifying energy condensed within the blade, which could to some degree cause confusion.
Of course, even when the Hidden Edge was stimulated, it did not cause earth-shattering noises or majestic commotions like other Immortal Artifacts.
It would only produce an increasingly powerful edge on its blade.
The Hidden Edge Sword could not only sever defenses but also cut through the opponent's attack.
