Naruto: the Darkened Ninja Way

Yu Ning accidentally traveled to the world of Naruto, became Uzumaki Naruto, and awakened the blackened ninja system. So he continued to practice the ninja way that was completely different from Naruto, becoming more and more indifferent, but also more powerful! Even when his strength exceeded the shadow level, it still couldn't change the repulsive looks in the villagers' eyes. Seeing the hatred and contempt in the eyes of the villagers towards him, a sneer gradually appeared at the corner of Yu Ning's mouth... Didn't you say I was a demon fox? Then I will become a real cold-blooded monster! Let Ninja Dao go completely dark! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
