cruz training under sasuke uchiha

As Cruz walks to the training grounds where he was planned to meet Sasuke all so many thoughts were in his head. Cruz keep wondering what he will learn, how he will improve, and most important thought in his head to him was what different genjutsus he'll be learning with his sharigan. As he kept walking he sees Sasuke form a distance. In so much excitement he waves to him and says “Hey Sasuke what will we be learning first!”

Well Since you left i can't teach you the jutsu's now that you leave yoour either a missing nin and you cannot survive that or become a sand ninja.
