Clearing the Lesser Evil

'After becoming a Supreme-Grade Artifact, Arcane Silver is upgrading itself at an incredible speed.'

Before the Arcane Silver could devour the Black Tower, it was already a high-level supreme grade artifact.

Since it devoured a high-level supreme grade artifact like Black Tower, Leo was not surprised at the fact that his Arcane Silver Sword was trying to upgrade itself to the Legend Grade.

'That's why I already like the artifacts or talents that could upgrade themselves as long as they were provided with enough resources.'

After Leo and the Arcane Silver became the Supreme-Grade hero and the Supreme-Grade artifact, their growth was very fast and it was all thanks to Leo's adventures in the other worlds.

'However, I wonder whether it could upgrade to the Legend Grade.'

Nevertheless, there was something that was bothering Leo a little and it was the grade of the World that limits its native from reaching the Legend Grade.
