Then a year essence sub-pool that channel to tributary of River of Time outside into the square pool was created using three rank eight time path Immortal Gu; Early Autumn, Mid Autumn, and Late Autumn. Rank eight Blood Asset Immortal Gu was added on the pavillion, releasing blood-red light, to harness its effect ,p which was to protect a portion of the immortal materials or Gu worms during refinement. If the refinement failed, some of these immortal materials or Gu worms could be restored afterwards using blood asset Immortal Gu. Rank eight Water Refinement Gu, which was used to contruct Refinement Sea, was used to process the tributary river of time water along with Refinement Sea's Refinement Water to create the water needed to refine gu. Aside from these, there are other twenty supplementary immortal gu worms, including the three rank eight time path immortal gu above, as well as over a million supplementary mortal gu worms of numerous types.
