My Rusty Sword Can Cut Through the Heavens

After three years of tempering, the sword's heart was covered in dust. On the day Ye Chen was expelled from the school, his finger bones were broken, but he held half of the rusty sword in a pool of blood. "This body can be broken, but the sword bones cannot be broken!" When the rust peels off, the sound of the eternal sword resounds throughout the nine heavens—— What he holds is not the sword, but the entire kendo.
