Start with Naruto and Play with Space!

[Hokage] [Space] [Sonjutsu] [Decisive Killing] [Multiple Heroines] In the 39th year of Konoha, Feng Xiang Yuyi was born into a down-and-out swordsmanship family on the edge of Konoha, carrying a "portable space" with a radius of 5 meters. The neighbors are Moonlight Hayate, who still has a runny nose, and Uozuki Xiyan, who follows behind her all day long and calls her brother. Born into a small family destined to become cannon fodder, Yu Yi not only did not panic, but began to quietly develop his own golden fingers: the space automatically absorbs natural energy to strengthen the body; after practicing chakra, the space turns into endless blue strips; he can even perfectly integrate chakra with natural energy, without the need for seals, to follow the magic of magic! The Third Ninja War broke out, and Yu Yi, who graduated early, clenched the long sword in his hand. From the "Nothing Slash" that attaches the power of space to the blade, to the "Flying Thunder God Slash" that develops its own space coordinates.
