Returning to the exclusive space, Su Xiao placed Dragon Slash on the desk, with two white weapons beside it for sacrifice.
Attempting to use the Supreme Blade Skill, a lump of iron-black ghostly light appeared in Su Xiao's hand, swirling in a vortex shape.
As the iron-black ghostly light approached the two white weapons, it seemed to come alive, directly enveloping the two white weapons.
"Kaka～."
The two white weapons wrapped in the iron-black ghostly light emitted a creaking sound as if being ground down.
After dozens of seconds, a wisp of white crystal shard floated out from the ghostly light, drifting toward Dragon Slash.
Dragon Slash absorbed the crystal shards directly, emitting a cold gleam, the blade becoming sharper, and the body of the sword tougher.
Whether it was an illusion, Su Xiao felt Dragon Slash looked a bit more splendid than before, but its appearance hadn't changed.
Checking the attributes of Dragon Slash, he found its blade value had reached 76%.
