Only after settling into the Naruto world does he gradually discover that Konoha's ANBU have infiltrated the village so deeply that they can even sideline the Hokage. Just as Konoha is caught in turmoil and on the brink of collapse, a young man steps forward!

And so, Konoha gains another living legend. Years later, Yeying Jifeng becomes a peak-level, Super-Kage-class powerhouse...
