It was not just speed.
The ability to change directions in an instant and the terrifying explosive power… They shocked the black-robed old man deeply.
Was this really something a young man could do?!
The black-robed old man could not hide the shock in his heart.
However, Chu Feng would not lament with him.
The black saber was like a black dragon that had darted out of the night. With a terrifying dragon roar, it suddenly slashed at the black-robed old man.
After fusing with the emperor-level saber intent in Nameless, the Demon Slayer had completely transformed.
According to Old Mo, even if the Demon Slayer was still a blade prototype, it was already not inferior to some Master God artifacts!
Boom!
Like Mount Tai pressing down, the Demon Slayer smashed towards the black-robed old man!
"Not good!"
A trace of fear appeared in the black-robed old man's eyes.
