Ten Days Immortal Gu

Ten Days is one of five time path Immortal Gu that Lang Ya land spirit hands to Fang Yuan, counting those from Lang Ya Sect’s treasury and those exchanged from the variant humans. The five are part of what Fang Yuan takes instead of refinement path true meaning. ^{ch. 1751}

Three of the five are rank six, and Ten Days is named among them beside Yesterday and Successive Years, while the other two are rank seven. ^{ch. 1751}

The three rank six Gu are described as just passable and, at most, supplementary Immortal Gu. ^{ch. 1751}
