I Only Use the Sharingan? I'm Afraid My Technique Is Too Strong!

This book is also called Ninjutsu for All: Only I Have the Sharingan Lu Yu traveled to a parallel world. It was very much like a fantasy world of immortality, but why did everyone use... Ninjutsu? Lu Yu, who had no huge amount of chakra, no blood inheritance limit, and no talent for ninjutsu, thought that his life would be miserable. At this time, I discovered that I had awakened the Sharingan of the Uchiha clan! "Is there no Sharingan in this world?" From then on, Lu Yu embarked on the road of replicating ninjutsu. "He directly copied my A-level ninjutsu!?" "What, you can even copy my blood inheritance limit?" On that day, in the global competition, rules were set for Lu Yu alone, prohibiting copying other people's ninjutsu! Lu Yu silently opened the kaleidoscope, okay, this time I will show you my own ninjutsu, "Tianzhi Zhenxing", "Susanohu" and "Kagi Earth Life"! This novel and its characters are purely fictitious.
