Here's the chapter:
"Tch, I'm playing around too much."
Silva exhaled once and his expression changed.
The sword came up and the black flames that covered it changed with it, no longer the controlled burn he had been using to push them back but something fuller, the fire responding to the shift in his intent and expanding across the blade until the heat of it was visible in the air around it.
He moved first this time.
He went at the nearest one without waiting for it to come to him, covering the distance in a burst and driving the blade through its chest before its arms could organize a response. The black flames followed the blade in, spreading from the entry point outward across the monster's body the moment the blade connected, and he pulled the sword free and was already moving to the next one while the first burned.
It did not survive.
