Born blind, the young man You Su had a bizarre nightmare on the eve of his eighteenth birthday. In the dream, he miraculously recovered his sight, but his cute junior sister turned out to be a monster covered in tentacles, and even his cold, mysterious master's wife revealed her terrifying true face, slicing off his neck with a sword! Awakening, everything seemed to return to normal, but when You Su stepped into Chuyun City, his blind eyes once again saw evil spirits that ordinary people could not perceive! Thinking he could be saved upon meeting an immortal master, who would have thought the other party pointed a sword at him saying, "You shouldn't have seen this." You Su then realized that this seemingly peaceful cultivation world unexpectedly hides a truth far more terrifying than demons!
