Naruto: Uchiha's God of Slaughter

Qin Mo, a die-hard Naruto fan, accidentally transmigrates to the war-torn Warring States period of the ninja world and becomes the third son of Uchiha Tajima. However, this identity brings him no glory; instead, he nearly dies at the hands of enemy clans right after his arrival! In a life-or-death crisis, he activates the [Uchiha Clan System]. As long as he does something beneficial for the Uchiha, he will receive generous rewards! Even more heaven-defying, on each birthday, the system grants him new powers!

With Qin Mo's heaven-defying cheat, the Uchiha clan rapidly rises! The destiny that once required bloody battles with the Senju clan is completely rewritten. Under his tutelage, Madara and Izuna even awaken the Nine Tomoe Rinnegan! Punch the Sage of Six Paths, kick Kaguya Ōtsutsuki, who else but me can be the ruler of the ninja world! "You ask what Uchiha Mo counts for? Let me tell you now. The things Senju Hashirama dares not do, I, Uchiha Mo, do. The people Senju Hashirama dares not kill, I, Uchiha Mo, kill. In short, the matters Senju Hashirama dares to meddle in, I, Uchiha Mo, will meddle in. The matters Senju Hashirama dares not meddle in, I, Uchiha Mo, will meddle in even more! This is me, Uchiha Mo! Not convinced? Then kill!"
