Heavenly Wind Qi Wall

An Eastern Sea Gu Immortal treats worldly horizon Immortal Gu as a way to enter the immemorial nine heavens freely and reduce the cost of breaking through the heavenly wind qi wall. ^{ch. 752}

Old Ancestor Xue Hu flies up and tears open the heavenly wind qi wall, entering white heaven. Gu Immortals at rank eight normally take their fights into the immemorial nine heavens so the surface is not ruined. Yao Huang and Heavenly Lord Bai Zu follow him. ^{ch. 813}

Cloud beasts that breed in the five regions follow instinct and fly toward the sky. Passing the heavenly wind qi wall, they would return to the immemorial nine heavens. The wall obstructs them, and fierce beasts and natural phenomena kill most of them on the way. Very few make it back. ^{ch. 1044}

Outside of the immemorial nine heavens, the heavenly wind qi walls are extremely thick. Grotto-heavens sit in the sky, and if they do not open up, they are hard to detect from the outside world. ^{ch. 1117}

Bu Zhen Zi says it is said that the heavenly wind qi wall is thicker than the five regional walls, and that seeing it himself makes the claim seem true. Heavenly wind qi makes up the wall. Even after Edge Link Camp stabs a tunnel through it, the wind rushes in and fills the gap quickly, so three Immortal Gu Houses have to stay almost touching as they charge. Some days later they break through and reach black heaven. ^{ch. 1239}
