Naruto: All Things Come Together

Other people's time travel is either Sharingan or Wood Release, but why am I from the Hatake clan? What? As a younger brother, Kakashi still dares to be awesome in front of me? A rare genius in a century? Fortunately, I got a synthesis system. As long as you have the materials, you can synthesize everything, including the Sharingan, the Mangekyou, the Samsara Eye, and the Blood Successor Snare... As long as you have enough materials, even synthesizing a world is easy! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
