Three hundred years ago, Chen Xun accidentally entered the ancient sword tomb and was entangled by the "Sword Curse of Reincarnation". From then on, he fell into a strange cycle of "three years of madness and three days of sobriety." When he was crazy, he was a crazy scholar who was shunned by people in the town. He held a mahogany sword and discussed swords with the wind and talked with fishes. When he woke up, he quietly tempered the principles of swordsmanship that he had learned in his madness into the inconspicuous wooden sword in his arms.
