Naruto: Yaoshou! Why Am I a Genin Who Only Knows Forbidden Techniques?

People are in Hokage, starting the ninja school exam. Yueguang Rin, who comes from an innocent third-generation poor peasant family, cannot even use the most basic clone technique. After experiencing the first failure in using the clone technique, in Mizuki's disdainful eyes, Yueguang Rin's savior - the necessary system for time travelers finally arrived. But the style of my system is a bit strange. The clone technique is guided by the God of Ninja and automatically transforms into a higher level ninjutsu - multiple shadow clones. With more and more battles, Tsukiko Rin mastered more and more ninjutsu. Multiple shadow clones, reincarnation in the dirty earth, power of the heavenly hand, tailed beast jade... I'm just an ordinary genin who doesn't even know basic ninjutsu! Why are you starting the Fourth Ninja War for me? This novel and its characters are purely fictitious.
