"Whoosh..."

Across the tranquil grassland, the gentle evening breeze drifted softly, stirring waves through the grass. The rustling of blades rubbing together floated on the wind, intertwining with the whisper of leaves in the distant forest.

"Pfft!"

Suddenly, at the border between the grassland and the forest, three earthen walls rose in succession from the grass not far from the woods.

"Trigger!"

Then, a low, cold shout rang out from behind the three earthen walls.

"Whoosh!"

The next second, a Kunai shot out from behind the walls. After tracing an arc through the air, it fell into the grass three meters beyond the foremost wall.

"Snap!"

The next moment, beneath the remote night sky and over the tranquil grassland, there came the sound of something taut and hard being severed.

"Bang!"

"Snap! Snap! Snap!"

As if it were a signal, the moment the fiery smoke erupted, a second, third, fourth... countless more clouds of fiery smoke exploded densely around it—on its left, right, diagonally left, and diagonally right.
