Su Yu traveled to the Warring States Period of Naruto and became Uchiha Yu. In this era of numerous ethnic groups and constant wars, he has been in a state of confusion from infancy to the present, but he has spent eighteen years safely. Without a golden finger, he is a Sharingan. His eyes failed to open successfully, his ninjutsu was limited to fireballs, and his taijutsu was a mess. He planned to just lie down completely, but was arranged by the clan elders to get married. It was not until his wife came to the house that Uchiha Yu was shocked to find that he had opened the door to the world of Naruto. Something is wrong with the method!
