Immortal Master of Kendo

I have a sword that can slay the sky! Do you believe it? An ignorant young man who walked out of the wilderness was holding a wooden sword and killing people, fighting demons, slaying heavens, and destroying gods step by step! Suddenly looking back, I am just an ordinary person. Just protect the softness in your heart. Since I was born in the world of sin, let me smash the sky of this world of sin! Let all gods and demons stand equally in all heavens and all realms! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
