knight leader wires

“Ever since, I have always been on the lookout for surprise attacks.”
While he spoke, Knight Leader “threw” the destroyed wires. Even if they were sharp,
they were still basically just strings. They shouldn’t have had any power to them, but
Kanzaki’s body flew back like a fired shell when they hit her.
“Gh...bh....!!”
This time, Kanzaki finally stopped moving when she struck a tree in the forest.
The destroyed wires were no longer wires. They had been gripped with such strength
that the metal wires had been compressed into a single mass and fired like a bullet from
a handgun.
