When Shen Jie Ao became a rank six Gu Immortal without a rank six Gu, he built White Bone Chariot from many rank five Gu such as the white bone wheel, with power comparable to a rank six Gu. ^{ch. 431}

Three Immortal Gu

That ingenuity carried him to rank eight. White Bone Battlefield combines three Immortal Gu and is stronger than White Bone Chariot. With it he dominated the world, killed an uncountable number of Gu Immortals, and left the righteous path helpless. ^{ch. 431}
