On the bloody battlefield of the Third Ninja World War, when the sixteen-year-old Uchiha Xiao was about to die, he awakened the "training proficiency system" - swinging the sword to increase proficiency, forming seals to increase power, and the Sharingan was activated for a moment, and his strength became more refined!
He is Uchiha Sasuke's biological brother. He is calmer than Itachi and tougher than Sasuke. He has experienced battles on the battlefield and holds a heaven-defying system, but in the end he cannot escape the fateful whirlpool of the Uchiha clan.
Sharingan goes from single magatama to kaleidoscope, ninjutsu goes from high fire ball to high fire extinguishing, swordsmanship goes from basic slashing to Uchiha secrets, every proficiency breakthrough is a rebellion against fate!
The scarlet of the night of genocide, the weight of brotherhood, the conspiracy of Konoha's top brass, the temptation of the pinnacle of the ninja world...
Uchiha Xiao held a kunai, and his scarlet Sharingan reflected the mountains and rivers of the ninja world: "With the system in hand, the day my proficiency reaches the peak, that's when I will rewrite the tragedy of Uchiha and take charge of the order of the ninja world!"
This time, Itachi is no longer lonely, Sasuke is no longer confused, and the glory of Uchiha is reshaped by me, Uchiha Xiao!
