Akagi

If there's someone who's mastered 'Hundred Birds Born' - the number one assassination sword, and that person is standing before you, then... you're already dead! No one can describe the elegance of that sword, just like no one can escape a 'silent fart' in a closed carriage... This is a story about a 'secretive' man transmigrating to the Xianxia world. Very interesting, really, I'm not kidding.
