There are only Senju and no Uchiha in this world. Yes, this is a world with only Asuras and no Indra, a world where no existence has ever existed.
Because of the excess of Yang power, everyone lives a long time, and the longer they live, the more pain they will suffer. This is especially true for Senju.
Without the existence of Uchiha, the Senju are the first ninja clan, so they are feared and excluded by other ninja clans who are weaker than them.
Because of some subtle influences over the years, even though Senju is the number one ninja, he still works for the nobles.
When Hashirama was a child, because there was no Madara or a boy with the same great ideals and ambitions as him, Hashirama slowly darkened due to doubts and distrust, and forcibly convinced other ninjas to let them build a village together.
It wasn't until one day that Senju Hashirama was accidentally mentally linked to another world, and he didn't know that there was such a person. Their ideals and beliefs were combined, just like each other's halves, both physically and mentally, they were closely connected to each other. His Apocalypse Uchiha Madara
Senju Hashirama was very jealous, so he and Senju Tobirama studied time and space ninjutsu and planned to snatch all the Uchihas in that world.
Finally they succeeded, and Madara Uchiha from the End Valley of another time and space and Izuna and Uchiha who were resurrected for some unknown reason were all stolen.
As for what happens in the other world, they don't care.
After all, without Uchiha, without the power of Yin, the overly powerful penis and empty soul are like a walking zombie, which is enough to torture many people crazy.
When this problem is discovered in another world, it is none of their business.
