"What sort of sword is this!?"
Despite wearing Heaven's Punishment, it was still not enough to withstand the sharpness of the sword.
A sword's sharpness was not only determined by the sword's physical sharpness, it also depended on the Sword Intent contained within the sword.
Some ancient divine swords could only have their Sword Intents sealed when placed in a scabbard. The moment it was drawn out of the scabbard, just a look at the sword could be enough to inflict injuries on someone, despite not touching its blade.
This nameless ancient sword was as such.
For someone to use his hand to grab the blade of a sword of that would reign sovereign amongst swords, it was an act of blasphemy towards the ancient sword.
