Thousand year profound ice

Along the way through a public grotto-heaven, thousand years profound ice is named among small to mid sized resource points with plentiful storage, together with hundred years profound ice, ice mirror snow lotus, mystical frost water, and heaven craft divine jade. ^{ch. 1638}

The same list of resource points, including thousand years profound ice and hundred years profound ice, appears again when the grotto-heaven is described as opening only once a hundred years and thus accumulating many resources in closely packed small and mid sized points. ^{ch. 1815}

Deep in Eastern Sea’s icy sea area, a huge ice mountain on the pitch black sea floor is made from thousand year profound ice. Standing near it covers eyebrows and hair in frost, and a rank seven Immortal Gu House’s dark blue light is not enough defense against that cold. ^{ch. 2230}

Su clan sends two rank seven Gu Immortals with Moving Frame Pavilion to crack pieces from the mountain and move them into their immortal apertures. Ice poison starfish and sharks make the work dangerous even for that force. Su Ming Wan had found the underwater mountain after much trouble; after excavation the ecology turns chaotic and later attempts carry much greater risk. ^{ch. 2230}

Eastern Sea holds abundant ice and snow immortal materials in that sea area. Su clan gathers the profound ice to hand over as water path resources rather than give up their own resource points. ^{ch. 2230}
