Naruto Is an Uchiha

From the start, on the day of the clan massacre, he awakens a soul-swapping golden finger. He immediately swaps the souls of Hiruzen Sarutobi and Uchiha Fugaku. Hiruzen becomes the Uchiha clan head, with his clan on the verge of annihilation. Uchiha Fugaku becomes the Third Hokage, planning the Uchiha Clan Massacre. The difference in their character is now plain to see. As a transmigrator, Uchiha Jian gets to witness the different timelines unfold, just as he expected. The Uchiha clan's long-held wish finally makes a breakthrough in Hiruzen Sarutobi's hands. Uchiha Fugaku becomes the Fifth Hokage!
