Roy vs 1500+

The swarm was made of ten thousand flesh rippers. 

The fire river killed 7800 of them, turning them to dust instantly, and set the rest ablaze. 

Two hundred had their wings burned. More than half of these 200 rippers crashed to the ground, breaking into pieces, and the rest smashed into trees, dying miserably.

8000 have died.

Another 2000 were dying.

The fire jumped off their corpses and set the poor trees ablaze.

Against their will, they became candles that brightened the area and forced the darkness to recede to the dim shadows cast by the far-away cliffs. 

Overhead, the fire river, unsupported by magic, was like an arrow at the end of its flight!

That didn't escape the experts' notice.

Arlo waved his hand, and the Joker's tent was reverse summoned.

It vanished from the surface of this world and reappeared in his storage ring.

"Move back." 

Meanwhile, Roy commanded everyone to widen the distance between them and the reclining fire river.
