Thanks, I wanted This type of explaination!
*as pradattauchiha lands the final slash, it barely cuts the dummy*
Urumi: "The sequence of slashes were alright but the final blow slacked power and ferocity. And you don't need to add chakra to your hands nor to your blade. Thea idea is to learn how to use your blade with such power to cut this dummy in to pieces without using the help of chakra but simply, with the correct footwork and body weight usage.
Give this another go."
*Urumi pushes another dummy towards pradattauchiha*
I perform the same series of slashes again and again, holding my hand firmer towards the dummy and creating various slashes both horizontal and vertical and then channel my chakra to my HANDS so that not the blade's power, but my own power increases in making the final cut to the dummy's chest
