Naruto: Madara Uchiha Stabbed Me in the Neck from the Start

After transmigrating into the world of Hokage, I open my eyes to Madara Uchiha’s kunai slicing across my throat. The instant I form the hand seals for the Summoning Technique, a clone clad in ancient armor rises from the smoke. I trade Fire Release attacks with the Uchiha father and son, pouring my skill points into healing techniques. My blood-drained body is healing, but my chakra is nearly depleted.
