Fukusho continued to practice after his sensei had urged him to continue. It was not that interesting since it was either painful or simple. Either way Fukusho wanted to be able to control his chakra so he could balance the kunai perfectly without pain. He took the knife and continued to practice making absolutely no progress at all. Maybe he was trying to hard and it was ruining his concentration. Either way the sensei called them together for an explanation soon. Fukusho heard what Kuro was getting at but he really didn't get why this would be that complicated as improving your concentration. Then again Fukusho didn't really get most of these exercises as much as he trusted his sensei would use them to make him a stronger ninja. "Sensei, what's the next test, are we fighting a grizzly bear with pine cones?" Fukusho asked.
