I concentrated on the Katon chakra, focussing on it, I am perform the Snake → Ram → Monkey → Tiger hand seals, and the chakra becomes much more concentrated and stabilized... I released the chakra as gas into the clone's direction (3 meters ahead of me), the gas is travelling through the air, being stabilized by my katon chakra, the gas hit your clone, The clone didn't fade away, but there are some burn marks left on the clone, because of the warm chakra, the gas came in his eyes, it hurt in his eyes, he couldn't see much, and fell, the clone was also coughing a little bit
