firstly u need to learn how to force your chakra into another into earth, place your hands on the ground and slowly push chakra into the ground infront of you
thats fantastic, thats the first thing you need to do but to help you with the next step you need to shock the ground instead by blowing chakra into the ground
okay! (tries again, places hands on ground creating a steady flow of chakra into the ground to build up a mound in front of him....as the mound builds up and while holding the steady flow he charges up a larger amount of chakra and then blasts it out of his hands boosting the stream in one large jolt )
