Demon Slayer: the Strongest Road Idiot Teaches the Pillar to Slay Ghosts!

Roronoa Zoro, a man who lived to become the world's greatest swordsman, after a fierce battle, he and his sword were lost together into a strange era where evil spirits were rampant. The swordsman here uses a technique called "Full Concentration and Breathing" to kill ghosts? Sauron said: I don't understand, but it's not a big problem. When the Demon Slayer Corps was having a headache over a demon, the man with the green algae head had already slashed through a mountain with three swords. While the pillars were practicing hard in the wisteria flower pattern, Zoro was fighting desperately with his sense of direction on "how to walk from the back mountain to the butterfly house." Flame Pillar Purgatory Anjuro: "Oh! This young man, your swordsmanship is full of enthusiasm! How can you be so powerful without the need for breathing techniques!" Sound Pillar Yu Zhuan Tianyuan: "This is the most gorgeous slash! I approve of you!" Insect Pillar Butterfly Ninja: "Is he... Really human?" He didn't know how to breathe, but he used the three-sword style wrapped with domineering energy to open a new door to the ultimate swordsmanship for the pillars. Muzan, the ancestor of ghosts, is about to face a real Asura from another world. But, before that, who can tell him where the meeting point for the final battle is? !
