The blind "Sword Blind Man" uses the scabbard as a sword, and with his clear mind, he realizes that "all things are swords". From a sincere young man to a melancholic traveler, from the evil and charming night hunter to the master of enlightenment, he has stepped through betrayal and death, just to protect one person, clear the world, and break taboos.
"The heart of the sword is immortal. Even if you are blind and disabled, you can still control the ups and downs of the world."
Concept: Feelings that are unacceptable to the world may be the light that illuminates the hypocrisy of the old order.
