In order to cure his sister, Lin Xun went out to look for medicine and was tricked into falling off a cliff. On the cliff, Lin Xun accidentally obtained the disappeared kendo inheritance. From then on, in order to protect his sister in this world where the jungle is strong, Lin Xun will use the sword in his hand to walk an invincible path that is unique to him.
