Well clones usually still display properties of the person, and if they're getting hit by a gentle fist tech, the residual damage being down is also hurting the users organs, which would make them bleed. (Much like how Hinata spit up blood when Neji hit her)Its better though a little weird with the "spitting blood thing". Why would the clone spit blood? I need an anwer?
Next, begin to hit my clone all over while injecting chakra to close his tenketsus. Then finish him by releasing chakra out of your palms in a burst to send him flying.
Neji runs straight forward to the clone with his Byakugan active and begins to strike the clone. Having his index and middle fingers out, with every strike, injects chakra into the clones body, closing his tenketsu. Starting around the chest striking it continuously down to around his lower leg and then back up to his top right arm. Hitting him continuously he then places a lot of chakra within his palm and goes full force into the hit and strikes directly at the center of the clones chest, making him go flying back and disappearing.
