Ice and Fire Yin-Yang Well

Biodata

Site Features

The well lies at the base of an inverted-cone valley beyond Dugu Bo's poisonous miasma. Its central pool is split into two non-mixing halves: one milky-white and lethally cold, the other vermilion and intensely hot. The surrounding natural energy is so dense it resembles tangible mist. The springs themselves were formed by the residual origin power leaking from the fallen Ice Dragon King and Fire Dragon King beneath the valley. 15 81 180

• Ice spring — Milky-white water that emits bone-piercing extreme cold. 15 81
• Fire spring — Vermilion water that bubbles with extreme heat. 15 81
• Immortal-herb garden — The valley supports rare medicinal plants whose fragrance can stimulate soul power. Luo Nan later stated that he had harvested most of its premium immortal herbs, leaving primarily immature or less useful specimens. 15 18
• Dragon King burial ground — Di Tian identifies dormant dragon souls and dragon essences beneath the springs as the remains of the Ice Dragon King and Fire Dragon King. 81
• Dragon King inheritance site — The underground remains retain inheritances of ultimate ice and ultimate fire. An inheritor requires exceptionally pure Dragon Clan bloodline, a body capable of enduring the elemental cleansing, and compatibility with both ice and fire or a constitution able to balance them. 179 180
• Soul Core catalyst — Its immense ice-and-fire energy can be drawn into a cultivator's meridians to catalyze the compression and qualitative transformation required for Soul Core condensation. 154
• One of the three great treasure basins — Di Tian identifies the well as one of Douluo Continent's three supreme treasure lands. 179

History

Luo Nan sought the well after learning that its immortal herbs could repair Tang Yuehua's mutated Martial Soul and break her level-nine limit. After gaining his eighth spirit ring, he crossed Sunset Forest, found Dugu Bo's Green Phosphorus Poison Array, and burned a passage through it with Golden Dragon Sacred Flame. 9 14 15

Inside the valley, Luo Nan harvested immortal herbs and consumed the Earth Dragon Golden Melon, which strengthened his body, purified his dragon bloodline, and raised his soul power to level 86. He later used the Octagonal Mysterious Ice Grass and Blazing Apricot Delicate together with the well's waters to undergo Ice and Fire Golden Body Refining, gaining ice-and-fire immunity, elemental control, and level 90 soul power. 15 17

Before leaving after his first harvest, Luo Nan consumed Autumn Dew to more than double his spiritual power. He also removed most of the garden's mature, high-grade immortal herbs for later use. 18

After subduing Dugu Bo, Luo Nan converted the former occupant into the well's sworn guardian. Dugu Bo was ordered to kill any unauthorized intruder and protect every plant in the valley. 16 50

Luo Nan later used the well's dense elemental environment to condense his first Soul Core, whose patterns carried his ultimate light, fire, and ice attributes. 31

The well later became the bargaining stake in Luo Nan's negotiations with Di Tian. Luo Nan initially withheld its location to compel the Beast God into granting him a favor, but eventually agreed to reveal it in return for help resolving the conflict between his light- and dark-attributed Martial Souls. 55 57 58 79 81

Once brought to the site, Di Tian confirmed the Dragon Kings' burial ground, guided Luo Nan through the formation of Yin-Yang Complementary Dual Soul Cores, and ultimately instructed Luo Nan to protect the well from those with ulterior motives. 81 82 83 84

Luo Nan later brought Dugu Yan and Ye Lingling to the well to absorb immortal herbs suited to their Martial Souls. Afterward, he again instructed Dugu Bo to remain at the site, cultivate there, and protect the remaining herbs from outsiders. 88 89 90

After Dugu Bo reached level 95, Luo Nan taught him the Soul Core Condensation Method at the well. During the attempt, the spring's extreme ice-and-fire energy entered Dugu Bo's meridians and served as the catalyst for his Soul Power's compression. 153 154

Di Tian subsequently deemed Luo Nan qualified to receive the inheritances of the Ice Dragon King and Fire Dragon King, offering to personally escort him beneath the well. Luo Nan initially refused the proposal, while Di Tian explained that no current Spirit Beast possessed the necessary combination of Dragon Clan bloodline, physical strength, and ice-and-fire compatibility to inherit the remains. 179 180

Defenses and Access

• Green Phosphorus Poison Array — Dugu Bo's toxic miasma surrounds the valley, corroding nearby vegetation and deterring intruders. 14 15
• Poison immunity — Luo Nan can cross the miasma unharmed after completing Ice and Fire Golden Body Refining. 81
• Extreme spring waters — The well's ultimate ice and fire are deadly even to powerful Spirit Beasts; entering the underground inheritance area without the necessary bloodline, physique, and elemental compatibility is fatal. 180
• Dugu Bo's guardianship — Dugu Bo cultivates at the site and has sworn to defend it with his life. 50 90
• Luo Nan's prohibition — No one, “even the King of Heaven,” may enter without Luo Nan's permission; trespassers are to be killed without mercy. 50

Relationships
