Cloud ladder tree

Shen Cong Sheng names cloud ladder trees as rank seven immortal plants. The tree has dense wood path and cloud path dao marks. Every hundred years it grows by ten inches, which is one step of a ladder. Cloud ladder trees are a rank seven immortal material. ^{ch. 1890}

The leaves of ten thousand year old cloud ladder trees form the rank eight immortal material cloud ladder leaf heart. Once all of the cloud ladder leaf hearts are taken away, the cloud ladder tree collapses into a pile of wood dust and becomes an ordinary material. Leaves with an empty heart-shaped space mark trees whose leaf hearts have already been removed. ^{ch. 1890}

On an island inside the blue dragon whale, explorers find a dense forest of such stripped trees; touching the trunks turns them to wood dust, and a search finds no remaining leaf hearts. Cloud ladder trees are quite rare in ordinary conditions. ^{ch. 1890}
