Formation Flag Immortal Gu

Dancer Hong Yun places the incomplete immortal formation on a sand dune, showing that the formation can be moved. Fang Yuan learns that the incomplete formation contains formation flag Immortal Gu. Immortal Gu Formation Flag at rank seven is one of the Immortal Gu he needs, and he obtains the incomplete formation in exchange for immortal materials from Thousand Transformations’ will. ^{ch. 1418}

In Mini Central Continent he sets up a self cleansing immortal Gu formation that uses self love Immortal Gu as the core and formation flag Immortal Gu as the supplement. Once activated it cleanses harmful dao marks constantly, and because of formation flag Immortal Gu the formation can be moved temporarily: he can take it out for use or place it back into the sovereign immortal aperture. ^{ch. 1422}

The new five regional limit formation adds earth vein Immortal Gu as well as Formation Spirit and Formation Flag. With Formation Flag, Fang Yuan can move the whole formation directly from his immortal aperture to the outside, or move the formation from the outside five regions back into his immortal aperture. ^{ch. 1809}

He later adds earth vein Immortal Gu, Formation Spirit, and Formation Flag to the five regional limit formation. While recuperating he raises all of the Immortal Gu in that formation to rank eight. ^{ch. 2174}
