Solar stepped into the training ground and looked around it was quiet and peaceful, he got one marble out and laid it on the sand. Solar closed his eyes and began to concentrate, he began doing hand seals to help him concentrate. He then brought chakra up to his ears and in his head he imagined a hearing aid, then imagined wind chakra going into that, then that it was forming around his ears. He murmured the words “Hilkyju” he opened his eyes. Solar got up and picked up the marble he threw it as far as he could. Solar could not even hear it going through the wind. Solar got out another marble and placed it on the sand again, this time he brought chakra up to his ears then in his head he imagined blue chakra then the chakra was forming into a hearing aid, he then imagined wind chakra going into that, he then said “Hilkyju” out loud, he then picked up the marble and threw it at least 20 feet, as the marble was going further away the sound was fading more and more “That must have been al least 50 feet or more” Solar dispersed the jutsu and walked out of the training ground
