I gathered my chakra and focussed very good. I released the chakra and channeled into the brains of your clone. I snapped my fingers and while snapping them I manipulated the chakra structure inside his brains and disrupted his chakra flow, what caused his senses to be affected. He believed that he saw many bright lines on his body, forming a grid. Then the body split apart into each grid and made 40 little ones of himself. All those little ones were running around because of the confusion, and angry that they were so small. In reality your clone was just running around because of the confusion.
question: Can the opponent use handseals while being under this genjutsu? And could he break out of it with Kai?
