*SWOOSH*
The large wooden arrow made its way through the air and landed on the formation.
The arrow clashed against the formation and shattered into a million pieces. The formation didn't even fluctuate. Sam just looked at the trees without any reaction.
He could have easily shot down the arrow, but he wanted to see the extent of these attacks and their effects on the formation. He was surprised and intrigued. The formation didn't fluctuate but the impact is nothing to scoff at.
It would cause serious damage if a cultivator of his level was hit by it.
More arrows came from different trees, Sam still let them hit the formation. Nothing happened. There is no change and the people inside the city felt a sense of safety because of this. At this moment, Sam noticed something else.
He saw that there is something happening to the first tree that's hot the arrow.
