Lu Yang accidentally traveled through a doomsday world.
As a "blank slate" incompetent person, he is incompatible with this world of chakra and ninjutsu.

Using the knowledge of Hokage from his previous life, he improved the physique of the Uzumaki clan with a lot of chakra, and started as a double-blood successor...
And the Sharingan he longed for has never been found...
