Konoha: This Uchiha Is Too Cautious

Where the leaves dance, fire burns unending. The flame will continue to light the village and let new leaves sprout. But alas! We can only dwell where the firelight doesn't reach, enduring the bitter cold and darkness of winter nights—gazing at the bonfire we ourselves have built, yearning for its warmth and light, while fending off the malicious stares that pierce the darkness from time to time. No cheat abilities, no wise old mentor, no system. The protagonist rises step by step from a child without chakra to the pinnacle of the ninja world!
