Ch. 41A new ninjutsu
Shinsei considered developing a Lightning Release ninjutsu that could replace nerve signals and greatly accelerate his reactions, but recognized that the idea required extensive research. He obtained the Bringer-of-Darkness Technique from Hiruzen Sarutobi and was attacked by a shuriken on his way home.
- Shinsei reasoned that Lightning Release Chakra might replace the body's nerve signals, though he acknowledged that developing the technique would require detailed knowledge of nerves and human experimentation.
- Shinsei practiced activating cells with Lightning Release in his basement.
- Hiruzen Sarutobi told Shinsei he needed two more days to experiment with the sensory ninjutsu and offered him a choice from the Scroll of Seals.
- Shinsei reviewed the scroll's contents, selected the Bringer-of-Darkness Technique, and received Hiruzen's transcription of it.
- As Shinsei headed home, a shuriken flew toward him, and he dodged it before turning to look.
