It felt like there was a thunderstorm coming here. William's formation stored the lightning attack from Fang, and fueled the materials around, charging them and the formation to change the nature of the ring of fire around, turning it into a ring of lightning.
Then with thunder, the lightning arcs forming the ring now expanded, travelled fast, and crossed a large distance in the blink of an eye, penetrating through tons of bodies, and turning them all into ash.
"..." Fang stood in his place, motionless, watching all this happening without being able to say a single word. He even had his mouth open agape, while watching something that even he at his prime wouldn't be able to do something close to!
It wasn't just turning the fire into lightning, it was as if William's formation borrowed the fire nature of being berserk and aggressive, and gave it to the shy and short-timed lightning.
