Fan door wind

Fan door wind is a rank seven immortal material. It does not grow in deep forests, mountains, or the sky; it grows in the doors of mortal homes. When it forms, the mortal’s door cannot close and can only stay open. That phenomenon draws Gu Masters and Gu Immortals to collect it. At first nobody understood its use, but later methods and plans make it usable. ^{ch. 1403}
