At the Beginning, He Killed Madara and Used the Ninja World as a Gift to Marry Tsunade.

[No system + no harem + no brainlessness + no procrastination + no holy mother] [Homemade Ninjutsu] + [Make Up for Regrets] + [Decisive Killing] + [Susanata Tailed Beast, One Man Fighting the Four Kingdoms] + [Enemies the whole world, including myself] The blind man's divine sword will kill you Uchiha Madara with the first sword! ! God's will traveled to the Uchiha tribe that had not yet been established in Konoha. As a result, both parents died at the beginning and both eyes were disabled. "I'll go! Everyone starts with a kaleidoscope and rolls their eyes. I'm a blind person at the beginning, right?" But although God has closed the door and sealed the windows, he still knows how to dig out a dog hole for himself. Before she died, my grandmother gave Tianyi a scroll, which recorded a powerful ninjutsu passed down from generation to generation. "God-destroying thunder sword!!" When used on one person, not only can all the ninjutsu and skills of the opponent be taken away, but even the appearance can be copied! Although the conditions were harsh, God's will successfully tricked Uchiha Madara by acting cute and pretending to be stupid, and he wielded the first sword. "If you can't become a god! Then kill the god!" However, this ten-year-old body could not withstand Madara's powerful power, and was attacked by Black Zetsu. Although he managed to escape, he fell into a coma. When he woke up again, he unexpectedly appeared in the home of the Senju clan. "Are you okay? My name is Tsunade, what's your name?" If you hadn't seen it with your own eyes, you would never believe God's will. The golden hair, the gentle face, and the different tenderness in the anime all stirred his heartstrings. "It's okay, my name is Tianyi, and I'm from the Uchiha family..." The introduction is wonderful, please read the text!
