Immortal Herb

Biodata

Background / History

Immortal Herbs are exceptionally rare medicinal treasures whose effects can improve a Soul Master's physical fitness and raise the age limit of Spirit Rings they can absorb. Qian Renxin considers them one of the continent's most important opportunities for cultivation. 8

The Ice and Fire Yin Yang Well is an unusually fertile treasure basin for Immortal Herbs. Its mutually restraining cold pool and hot spring are formed from the remains of the Ice Fire Dragon Kings; their Extreme Ice and Extreme Fire energies accelerate the growth of nearby plants and enable the birth of Immortal Herbs. 27 106

After acquiring the Ice and Fire Yin Yang Well from Dugu Bo, Qian Renxin explores it with Yue Guan. Their initial search uncovers twenty to thirty Immortal Herbs, while some immature plants are deliberately left unharvested. 12 Later collections yield more than a hundred high-quality medicinal herbs, roughly half of which approach Immortal-Herb quality. 41

Qian Renxin distributes selected herbs to trusted allies, relatives, and Spirit Hall Venerables according to Martial Soul compatibility. These gifts strengthen Spirit Hall's senior members and secure their loyalty. 12 27 39 By the time he returns to the well in Chapter 106, the number of Immortal Herbs has greatly declined and will require thousands or tens of thousands of years to recover. 106

Properties and Limitations

• Immortal Herbs are so scarce that most Soul Masters cannot identify or safely use them; Yue Guan spent much of his life collecting knowledge of them after consuming one as a child. 12
• Compatibility matters more than age alone. The most suitable herb can improve a Soul Master's aptitude and break cultivation bottlenecks more effectively than a stronger but mismatched variety. 39
• Their effects may include improved Soul Power, cultivation speed, physical strength, mental power, Martial Soul evolution, elemental affinity, and Spirit Ring absorption capacity. 8 27 36
• Freshly extracted herbs should be absorbed quickly to preserve their medicinal potency. 27
• Excessive consumption is dangerous: conflicting residual medicinal effects can hinder future cultivation or damage the body. 35 66
• Certain herbs are lethal when taken alone or improperly prepared. The Octagonal Mysterious Ice Grass and Infernal Delicate Apricot can poison even a Titled Douluo if consumed separately. 12
• The Ice and Fire Yin Yang Well's abundance makes even several-thousand-year herbs comparatively insignificant to Qian Renxin, though such herbs remain valuable to younger Soul Masters. 29

Impact on Spirit Hall

• Yue Guan's absorption of the Singular Velvet Sky Chrysanthemum elevates him from level 94 to level 96 and earns him entry into the Worship Hall. 15
• The Venerables' herbs loosen longstanding cultivation bottlenecks; Guang Ling reaches Rank 98, while Qing Luan and Xiong Shi gain a path toward the same level. 39
• Jin E, already Rank 98, gains decades' worth of cultivation progress despite the extreme difficulty of advancing further. 39
• Qian Renxin regards the Well as a strategic resource capable of producing future Titled Douluo-level powerhouses when paired with sufficiently talented recipients. 41
• The herbs also allow Qian Renxin to cultivate trusted subordinates independently of Spirit Hall's ordinary reward system. 12
