Quasi-rank nine immortal material

Intact tiger-striped honey bee wings from immemorial remains give off metal path dao mark light visible to the naked eye. Fang Yuan judges that only a dao mark foundation at quasi-rank nine produces such visible dao mark light, so more accurately speaking the wings are quasi-rank nine immortal material. ^{ch. 935}

Quasi-rank nine immortal material holds so many dao marks that it shines with bright light observable with the naked eye. In theory it can refine a rank eight Immortal Gu, and a tiny fragment can refine a rank six Immortal Gu. Immortal materials at rank eight and quasi-rank nine together are enough to move even rank eight Gu Immortals. ^{ch. 936}

When Fang Yuan sells immortal materials, the more precious quasi rank nine immortal materials are kept in his possession. ^{ch. 952}

Most of Fang Yuan’s quasi-rank nine immortal materials come from the Gu formation in Earth Trench, while some rank seven and eight immortal materials come from Falling Heavenly River. Their value is too high for casual use as ordinary Gu refinement materials at that time. ^{ch. 1073}

Only quasi-rank nine immortal materials radiate lights of dao marks. In the third-last layer of Crazed Demon Cave the dao marks are so dense that every piece of soil and rock is a quasi-rank nine immortal material, yet those dao marks are chaotic and cannot be used. ^{ch. 1188}

In Crazed Demon Cave’s seventh layer, every grain of soil and every piece of rock is a quasi-rank nine immortal material, but the dao marks are chaotic and cannot be used. ^{ch. 1863}
