Yun Shu, who was born blind, had a bizarre dream on a rainy night. In the dream, he from another world transferred his heavenly cultivation into his body, giving him the ability to see everything in the world as his eyes, and he also left behind a bamboo sword engraved with runes.
"Do what you like, experience the joy of being strong, step on those who bully you, and let the world not restrain you!" With his own words from another world still in his ears, Yun Shu left Qingshi Town, where he had lived for sixteen years, and embarked on a journey with his sword in hand.
His world is no longer dark, and the wind and grass and all living things within a radius of a hundred feet can be clearly felt. When he first left the town, he used his extraordinary strength to save a young man who was kidnapped by human traffickers. Faced with the villain's counterattack, he suppressed the urge to kill in his body and chose another "strong man's way."
After that, he walked through Wuyin Town and got rid of the evil spirits of the black rocks at the bottom of the river; he traveled across thousands of mountains and rivers and tasted all kinds of flavors in the world. Using a bamboo sword as a pen and heaven and earth as a scroll, he explored the true meaning of power during his travels, and gradually understood that the joy of a strong man was not only conquest, but protection and perseverance were also of great significance. This is the story of a blind swordsman who writes legends in the world with his otherworldly power and inner morality.
