Discovery and Use

Whale Rubber was originally used by nobles and Soul Masters as a tonic during intercourse; its cultivation value had not yet been discovered 13.

Yun Yuan identified its true use: properly treated Whale Rubber strengthens a Soul Master's physical constitution, enabling the absorption of soul rings with higher Year Limits 14. He began consuming it periodically after the discovery to improve his body 24.

Over roughly half a year of use, Yun Yuan's physique became comparable to that of a Beast Martial Soul Soul Elder, contributing to his ability to absorb the thousand-year Darkgold Fearclaw External Attached Soul Bone 31.

Processing and Refinement

Whale Rubber must be pretreated before it produces its physique-enhancing effect 14.

  • Calcine it with soul power flames or high-temperature flames.
  • Continue until it becomes soft, translucent, and free of impurities.
  • After consumption, guide its violent energy with soul power.
  • The refinement tempers the flesh, meridians, and bones while purging impurities from the body 13 14.

Martial Soul Hall Monopoly

After Yun Yuan explained the material's value, he and Qian Xunji planned to control the Whale Rubber trade for Martial Soul Hall 14.

Step Action Result
Collection Gather and monopolize Whale Rubber supplies. Martial Soul Hall secured control over the resource 14.
Supply chain Establish an industry linking the Great Sea to inland markets. The Hall built an integrated ocean-to-mainland supply chain over the following years 14 84.
Stockpiling Delay public disclosure while accumulating large reserves. Rival powers were left without access to the continental supply 14 84.
Public sale Reveal its true effects and sell supplies at a premium. Major forces had to purchase Whale Rubber from Martial Soul Hall at high prices 84 85.
Barter Exchange Whale Rubber for medicinal herbs. Martial Soul Hall amassed large herb reserves for Yun Yuan's planned alchemy system 85 86.

Impact

The revelation that Whale Rubber could raise a Soul Master's ring-absorption limit spread through the Soul Master World and made the material highly sought after 84.

  • The Seven Treasure Glazed Tile Sect, Blue Lightning Tyrant Dragon Clan, and Clear Sky Sect purchased supplies from Martial Soul Hall despite the cost and risks of sourcing them directly from the ocean 85.
  • Tang Chen intended to obtain high-Year Limit Whale Rubber himself by hunting whale-type soul beasts in distant seas, but was severely injured after encountering the Deep Sea Demonic Whale King 85 99 102.
  • Tang Chen's expedition also suffered severe casualties, and the Whale Shark he had obtained was lost in the encounter 99.
  • The Deep Sea Demonic Whale King that had endangered Tang Chen's expedition was later killed by Yun Yuan, Qian Daoliu, and Bo Saixi during Yun Yuan's hunt for his eighth soul ring 102 127 128.
  • Martial Soul Hall publicly credited Yun Yuan with deducing Whale Rubber's effects, helping establish his reputation as a “Grandmaster” 84.
