(Slow heat + no system + detailed description of battle + Uchiha)
The tone of the work has both gains and losses, and there is no systematic flow. It is too ridiculous to become invincible at a young age or to become invincible when participating in the war at the age of eleven or twelve. Uchiha Kageji grows up step by step, with flesh and blood, logic, and all characters have online IQs. Born from the ordinary, a genius will be found among mortals, a mediocre person will be found among geniuses, and he will eventually become invincible step by step.
"Am I on the same timeline as Minato Namikaze? This is the best era. I, Kagami Uchiha, will reach the top step by step."
