Douluo's Black Bamboo Sword

Introduction: Hard work may not allow you to defeat the enemy, but it cannot be denied that your strength is gained step by step through hard work. Wherever the heart goes, so does the sword. Maybe the enemy pointed by the sword is an enemy that you will find difficult to defeat in this life, but as a swordsman, you must understand: the direction the sword points is the direction of your growth! (A random plot!)
