Whale Rubber

Biodata

Properties and Effects

• Whale rubber is known for restoring virility, but Tang Shan identifies body strengthening as its more useful effect 6.
• Tang Shan believes hundred-year whale rubber has a modest effect on a Soul Master’s soul-ring absorption limit, while thousand-year whale rubber could help Su Yuntao attempt a thousand-year second ring 6.
• Its aphrodisiac effect makes Su Yuntao reluctant to take it. Tang Shan advises him to endure the effect and exercise rather than use it for its customary purpose 6 10.
• Tang Shan explains that its body-strengthening properties have gone largely unnoticed because healthy people have little reason to take an aphrodisiac, while weakened users may interpret the improvement as merely returning to normal health. He also estimates that hundred-year whale rubber might increase a soul-ring absorption limit by only a few decades, an improvement easily overlooked when most Soul Masters do not approach their existing limits 6.
• Its stimulation of qi and blood can accelerate soul-power circulation. In Su Yuntao’s experiment, the unusually rapid cultivation disappears once the medicine wears off; Tang Shan uses this observation to develop a theory linking qi and blood with soul power 10.
• Whale rubber does not remove cultivation bottlenecks. When Tang Shan takes it at Innate Full Soul Power, his soul-power quality improves, but his level cannot rise without obtaining a soul ring 14.
• Physical strengthening alone does not resolve every danger of absorbing an older soul ring. Su Haichao declines to reserve thousand-year whale rubber for himself because a ten-thousand-year fourth ring would also expose him to the soul beast’s Soul Shock; merely adding a few hundred years to his attainable ring age would not justify the expense 9.
• Its strengthening effect remains undiscovered by the wider Soul Master community when the Seven Treasure Glazed Tile Sect assesses Su Yuntao’s unusual second ring 39.
• Its customary aphrodisiac effect is not universally effective. Dugu Bo later explains that whale rubber has ceased to produce that effect for a patron whose available harmless tonics have also stopped working 138.

Preparation and Use

• Before heating, the family’s whale rubber appears as an irregular black lump. A heated portion turns golden, softens, and gives off a rich aroma 10 14.
• Su Haichao tries a small piece after purchasing it and notices a slight improvement in his physique 10.
• Su Yuntao eats roughly one-tenth of the piece and exercises while it takes effect. His short-term physical performance improves; afterward, his soul power rises from rank thirteen to fourteen. Tang Shan attributes the faster cultivation to surging qi and blood accelerating soul-power circulation 10.
• After a strenuous workout, Tang Shan eats whale rubber and cultivates through its effects. Its energy eases his soreness, repairs minor exercise injuries, strengthens his body, and improves the quality of his soul power. His body absorbs the energy before it can produce the feared “Evil Fire” 13 14.
• Tang Shan recommends eating the prepared portion while it is hot, warning against letting it cool and wasting its effects. Su Yuntao describes it as having little flavor beyond its aroma, while Tang Shan’s later portion has a rich flavor and a thick, springy texture 10 14.
• During Su Yuntao’s first use, Tang Shan has him perform sit-ups rather than push-ups or squats to avoid aggravating the aphrodisiac effects. His uninterrupted sit-up performance increases from approximately 190 repetitions to 300 10.
• Tang Shan postpones his own use until after Martial Soul Awakening to obtain the greatest benefit. After taking it, he cultivates under Su Yuntao’s supervision and emerges with greater vitality and a noticeable increase in height, which he associates with the connection between his Body Martial Soul and physique 10 14.
• The whale rubber already purchased by Su Haichao becomes part of Tang Shan’s preparation for attempting a thousand-year first soul ring 14.

Power Progression

The recorded grades distinguish whale rubber by age; they do not represent an individual piece advancing through cultivation stages.

Acquisition and Notable Holdings

Su Family Purchase

• Spirit Hall awards ten thousand Gold Soul Coins for Tang Shan’s theoretical work. Su Haichao uses this funding to send people secretly searching for thousand-year whale rubber 9.
• Su Haichao prioritizes his sons’ cultivation over obtaining a supply for himself, explaining that the money was earned by Tang Shan and should be preserved for the children’s future resources 9.
• The purchased material supports both Su Yuntao’s training and Tang Shan’s later physical conditioning 10 14.

Imperial Search

• Emperor Xue Ye asks Ning Fengzhi about promised ten-thousand-year whale glue. Ning Fengzhi confirms that people stationed in coastal cities will send it to the emperor as soon as they find it 90.
• Ning Fengzhi also suggests requesting the hundred-thousand-year piece held by Spirit Hall’s Heaven Dou City branch. Xue Ye has already tried, but Salas states that he lacks authority over material left there by a senior Spirit Hall figure for safekeeping 90.

Qian Daoliu’s Stored Piece

After first reaching the Limit, Qian Daoliu went to sea and killed a hundred-thousand-year whale-type Soul Beast. He brought its remains and soul bone back to Spirit Hall but personally retained its whale rubber, hoping to use it someday with Bo Saixi. After she rejected his romantic hopes by expressing a desire for a man who could become a god, he passed through Heaven Dou City and left the whale rubber at the local Spirit Hall 135.

When Golden Crocodile Douluo discusses gathering rare resources to strengthen Tang Shan, Qian Daoliu remembers the stored piece. He considers informing Golden Crocodile but stops out of embarrassment over revealing his youthful intentions and the material’s intimate reputation. The passage does not establish that the piece is retrieved or given to Tang Shan 135.

Dugu Bo’s Procurement

• Dugu Bo recounts having gone to sea to obtain whale rubber for a patron as part of repaying a life-saving debt. By the time he discusses the matter with Dugu Yan, whale rubber no longer provides the patron with the desired aphrodisiac effect 138.
