The man looked towards the new developments, stopping his progress for a moment. He narrowed his eyes and contemplated the source of the energy that controlled the skeletons. This was unlike his previous mission where he was dealing with the living. 'Aren't I?' He thought as he recalled that energy only resided amongst the living. This living being's energy was controlling the skeletons, obviously.
Knowing that the mausoleum housed that strange light, the skeletons were guarding it fiercely with a hive-like mindset and only the most precise attacks were capable of killing them... again... he knew what he'd have to do. He looked up towards the moon above and calculated the amount of light it was casting down into the graveyard. It was a decent amount, the small amount of clouds, around 3, were not around the moon, which wasn't in it's fullest capacity. To deal with the hive, he couldn't attack them individually, he had to attack at once, without harming the landscape, anymore than he already had.
He sent a rippling pulse throughout his frame and went through a series of hand seals, not wanting the chance of things going wrong. As he ended on the Rat seal, his shadow below began to wiggle around before circling around the Nara(1). He took a deep breath before beginning another series of hand seals, again ending on the Rat seal.
Again, his chakra pulsed throughout his body, except once it reached his shadow below it began to stretch out to connect with the nearest shadow, being the gate of the graveyard. Once it connected with the gate's shadow it pressed forward, using the entirety of the gate's shadow to connect with the nearest skeleton. Once it reached the first skeleton, it was all he needed before his shadow exploded with a large amount of his chakra, causing it to burst forward. It connected with the shadows of each of the skeletons, using their shadows to stop them from moving completely(2) before he managed to cover the entirety of the graveyard.
By this point in time, sweat had begun to bead on his brow, feeling a tad exhausted from the chakra it took to connect with the amount of skeletons, not to mention the amount it took to connect with the bigger enemies and the biggest new contender. He knew this next technique would handle his problems and thus, he begun the series of seals, yet again ending on the Rat seal. His breath had begun to quicken, from the amount of chakra being used but he pressed on. His shadow, given the command, began to rise up the legs of the skeletons, turning them pitch black. Because of his imitation technique, they were unable to move an inch, thus couldn't help but to take the punishment that was unfolding among their ranks. As the shadows covered each of the skeletons, it began to shrink down into the ground(3), the sounds of crunching bones being muffled from the thick layer of shadow around them.
As soon as they all disappeared into the ground, his stretched shadow vanished along with them, no longer connected with anything. As the connection vanished, the Nara was forced to his knees from the exertion, breathing heavily.
