𣵽焦（烏木案郭璞注江賦云大壑在東海外𣵽焦海所瀉源水注處也今取無窮無極義也）。

Weilu abyss (𣵽焦, wei-lu; wu + mu; checking Guo Pu's commentary on the 'River Rhapsody', it says: "The great abyss is beyond the Eastern Sea; the Weilu is where the source waters drained by the sea flow into." Here it is taken in the sense of being endless and limitless).
