Ice and Fire Yin Yang Well

Biodata

Background / History

Lan Tian learns of the well from memories of his past life and identifies it as a rare site where a cold spring and a hot spring coexist, producing abnormal vegetation and immortal herbs. At rank fifteen, he postpones his search until he is stronger enough to enter Sunset Forest safely. 20

Over six years, Lan Tian repeatedly surveys Sunset Forest and marks searched regions on his map. A parchment map recovered from a dead Soul Elder eventually points him toward an unexplored valley whose terrain matches the well’s expected location. 37 40 43

Lan Tian reaches the hidden valley and recognizes its divided hot-and-cold air currents, but retreats after discovering the lethal poison mist, scattered remains, and the probable presence of the fifty-thousand-year Medusa Empress. He takes a mist sample and develops a temporary suppressant before returning. 44 45 53

Using the suppressant, Lan Tian passes through the poisonous valley and reaches the basin. He harvests the Infernal Delicate Apricot and Octagonal Mysterious Ice Grass, consumes them, and uses the two springs to complete an ice-and-fire body tempering. 54 56 57

Afterward, he collects separate samples of the red and blue spring waters. He later develops a living-storage Soul Tool to transplant immortal herbs, returning to remove the Singular Velvet Sky Chrysanthemum while the Medusa Empress remains asleep. 58 62 65

Appearance

The well lies in a circular basin enclosed by towering cliffs, with sunlight entering through gaps overhead. Dense exotic vegetation surrounds two springs positioned only a few steps apart. 56

• Blue Spring — Deep blue water that emits bone-piercing cold and produces white mist. 56
• Red Spring — Crimson water whose heat distorts the surrounding air. 56
• Boundary — The opposing currents meet above the springs, forming a visible transparent barrier across the basin. 56
• Outer valley — Concealed by vines, dense shrubs, ancient trees, and pale-green poisonous mist. 44
• Soil — Carries both icy coolness and warmth near the springs. 54

Properties

Ice-and-Fire Tempering

The spring waters contain extreme cold and scorching heat. When Lan Tian enters the boundary between them after consuming the Infernal Delicate Apricot and Octagonal Mysterious Ice Grass, the opposing energies temper and ultimately merge within his body. 56 57

• Grants the conditions needed to fully absorb the two selected immortal herbs. 57
• Enables a constitution immune to poisons and resistant to extreme ice and fire after successful tempering. 57
• The water remains apparently unaffected after Lan Tian fills more than a dozen bottles, implying a much deeper source. 58

Botanical Cultivation Environment

The spring water nourishes the basin’s soil and gives its vegetation extraordinary vitality. The basin is filled with rare herbs whose Soul Power fluctuations are dense enough to be perceptible. 20 56

• The ambient Soul Power concentration is described as at least ten times higher than outside the basin. 56
• Lan Tian estimates that one year of outside cultivation is equivalent to one month within the basin. 56
• Immortal herbs rapidly wither if removed from the well’s soil and environment without specialized preservation. 56 62
• Water taken from the well can support a living-storage Soul Tool’s environment for transplanted herbs. 62 65

Poison Mist Barrier

The valley is surrounded by pale-green poisonous mist produced by the Jade Phosphor Seven Absolute Flower, which grows around the well while drawing on its cold and heat energies. 44

• The mist is lethal enough to leave human and Soul Beast remains throughout the valley entrance and slopes. 44
• Lan Tian’s herbal suppressant only slows the mist’s effects; it does not detoxify them. 53
• After gaining poison immunity, Lan Tian can cross the mist without suppressant medicine. 65

Known Immortal Herbs

• Infernal Delicate Apricot — A crimson, flame-like herb beside the red spring; consumed by Lan Tian for body tempering. 56
• Octagonal Mysterious Ice Grass — An ice-blue, octagonal herb beside the blue spring; consumed alongside the Infernal Delicate Apricot. 56
• Aromatic Silk Beauty — A pale-yellow flower growing in a damp, shaded corner of the basin. 56
• Singular Velvet Sky Chrysanthemum — Removed with a living-storage Soul Tool and consumed by Lan Tian, initiating his Indestructible Vajra Body physique. 65
• Eight-Petal Immortal Orchid 56
• Cockscomb Phoenix Sunflower 56
• Full Moon Wearing Autumn Dew — Later selected by Lan Tian as his next target herb. 56 66
• Narcissus Jade Muscle Bone 56

Guardians and Visitors

• Medusa Empress — A fifty-thousand-year poison-attributed Soul Beast that occupies the basin as its nest and commands poisonous Soul Beasts in the valley. She awakens when Lan Tian collects spring water, forcing him to escape with Giant Wood Burial. 44 58
• Jade Phosphor Seven Absolute Flower — The natural source of the valley’s poisonous mist and a protective plant sustained by the well’s extreme energies. 44
• Lan Tian — Locates the well after six years of searching, harvests its water and immortal herbs, and seeks to transplant its botanical resources to his fief. 40 58 62

Trivia

• Lan Tian compares the combined plant-catalyzing effects of Sun and Moon Shine Together, Endless Life, and Spring of Vegetation to a portable humanoid Ice and Fire Yin Yang Well; however, his range and growth speed remain below the true site’s. 40
• Lan Tian plans to use the well water, its soil, and his plant-growth soul skills to establish a smaller cultivation environment outside Sunset Forest. 58 62 64
