Lin Xian, a data analyst, accidentally transmigrates into a fantasy world. All he wants is to find a small house in Xiyun Village, lie flat, and live a quiet, peaceful life. Little does he know that the courtyard he brought with him is filled with ancient treasures. He treats them all as ordinary household items. The Heaven-Rending Banner, capable of splitting heaven and earth, becomes a place to hang his underwear. The Immortal-Slaying Dagger, which can kill immortals and demons, becomes a fruit knife for peeling apples. The World-Opening Sword is used every day to chop firewood for the stove. Even the iron pot he uses to cook chicken soup is the Hundred Herbs Cauldron, capable of refining supreme divine pills. The casual things he says are treated by the martial world as sacred principles; a simple chopping motion is mistaken by sword fanatics for the highest sword intent; and his thoughtless act of airing a quilt directly drives back a million heavenly demons invading the mortal realm. From the Azure Cloud Sect to the imperial court, from the martial world to the Nine Heavens and Ten Earths, everyone wildly imagines that he is a supreme immortal venerable living in seclusion. Only Lin Xian himself looks utterly bewildered: “I really am just an ordinary person who wants to live a peaceful life!”
