Naruto: I become stronger with more children!

WARNING: The story contains scenes of sex and violence. Only for people over 18 years old. David's soul traveled the ninja world and became a member of the Uchiha Clan and was even in the room of a beautiful woman. Unable to resist the temptation, he stayed up all night. After returning to the clan, he suddenly discovered that the Uchiha Clan had been exterminated! The only two people alive in the clan were young Sasuke and him... Isn't this the famous night of the genocide? I thought that the plot in the future would develop according to the original work, but I never thought that the [Wife and Children System] would appear. As long as David has more children and the Uchiha Clan prospers, he will be able to obtain various powerful and strange rewards... "Tsk, tsk... To revive the Uchihas! Look! I have no choice but to give myself up! Konoha, Danzo, the indecisive Third Hokage... aren't they expelling the Uchiha Clan? When my descendants are scattered all over the ninja world, we'll see who excludes who!" Note 1: English is not my language, I am using Google Translate. Note 2: The cover is not mine.
