Background / History

The Ice and Fire Yin Yang Eye is located in Sunset Forest, in a basin formed by a dead volcanic crater. Its center contains an oval spring split into two halves: a vermilion yang spring of extreme heat and an ice-blue yin spring of extreme cold, with the two sides remaining distinct while balancing one another 14.

Before Wang Chen entered, Dugu Bo had protected the area with Jade Phosphorus Seven Absolute Flowers and a concealed poison array filled with deadly toxins. Wang Chen avoided a direct approach by controlling a digging soul beast and tunneling dozens of meters underground beneath the poison array 14.

After entering, Wang Chen used the environment's herbs to strengthen his body, improve his martial souls, and prepare to absorb the central ice-fire poisons. He harvested numerous immortal herbs and spiritual medicines, then consumed the Fiery Apricot Delicate and Octagonal Mysterious Ice Grass before jumping into the spring to refine them together 14 15 17.

Wang Chen later dived to the bottom of the spring to investigate rumors that the remains of the Ice Dragon King and Fire Dragon King lay beneath it. Instead, he found a natural Taiji yin-yang fish formation that continuously drew in ice- and fire-element energy to sustain the spring. He confirmed there were no dragon king bones, remnant souls, million-year soul bones, or million-year soul rings beneath the site 18.

Properties

Yin-Yang Ice-Fire Balance

The spring naturally balances extreme ice and extreme fire. Its two halves do not disturb each other, yet their energies nourish and stabilize the entire environment 14 18.

• Generates dense ice-element and fire-element energy 18.
• Nurtures immortal herbs and high-grade spiritual plants over long periods 14.
• Contains ice and fire poisons strong enough to endanger Wang Chen before he strengthened his physique 14 17.
• Becomes gentle and non-destructive to Wang Chen after he refines the Fiery Apricot Delicate and Octagonal Mysterious Ice Grass 18.

Natural Herb-Growing Environment

The Ice and Fire Yin Yang Eye is described as a place where even an ordinary weed could become a top-tier spiritual herb after surviving for tens of thousands of years 14.

• Its soil radiates faint energy and feels warm and smooth beneath Wang Chen's feet 14.
• Its dense spiritual energy supports many immortal herbs, medicinal plants, and spiritual medicines 14.
• Its herbs are valuable enough that Wang Chen considers it one of Tang San's major future opportunities and deliberately seizes it first 10 39.

Poisonous Protection

Dugu Bo's defenses make the area dangerous even before the spring itself is reached 14.

• Jade Phosphorus Seven Absolute Flowers are planted around the site 14.
• A concealed poison array surrounds the Ice and Fire Yin Yang Eye 14.
• Wang Chen treats even accidental trace exposure as serious enough to prepare an antidote pill 14.
• He avoids forcing through the array and tunnels underneath instead 14.

Effects on Wang Chen

Martial Soul Evolution

The Ice and Fire Yin Yang Eye's herbs directly contribute to Wang Chen's martial soul growth.

• The Eight Petal Immortal Orchid increases the origin of both his Alchemy Furnace and Meridian Martial Souls, though it does not trigger immediate evolution 15.
• The Strange Velvet Sky Chrysanthemum and Narcissus Jade Muscle Bone primarily nourish his meridians and help evolve the Meridian Martial Soul to a top-tier level 17.
• The Fiery Apricot Delicate and Octagonal Mysterious Ice Grass transform his Alchemy Furnace Martial Soul into an ice-fire balanced furnace, with dragon-shaped flame inside and frost-white ice coating the furnace walls 18.
• After these changes, his Meridian Martial Soul gains a gold-and-silver masculine-feminine balance 18.

Physical and Spiritual Strengthening

Wang Chen uses the site as a cultivation foundation before hunting high-age soul rings.

• Whale glue and immortal herbs strengthen his body enough to endure higher soul ring impacts 14 20.
• Yearning Heartbroken Dew increases his spiritual power, helping him withstand ten-thousand-year soul beast soul shock 16.
• The Strange Velvet Sky Chrysanthemum helps him glimpse the threshold of an Indestructible Diamond Body 16 20.
• The ice-fire herbs increase his resistance to ice poison and fire poison 18.

Soul Ring Preparation

The Ice and Fire Yin Yang Eye is part of Wang Chen's plan to absorb soul rings beyond normal limits.

• He originally plans to use the Dream God Head Soul Bone, Blue Silver Emperor Right Leg Bone, whale glue, and Ice and Fire Yin Yang Eye herbs as his foundation 4.
• After harvesting and refining its herbs, he successfully absorbs a five-thousand-year first soul ring and later a ten-thousand-year second soul ring 20 21.

Story Role / Major Arcs

Targeting Dugu Bo's Herb Garden

Wang Chen wants the immortal herbs of the Ice and Fire Yin Yang Eye but does not intend to negotiate with Dugu Bo. Instead, he plants a nightmare seed in Dugu Yan's sea of consciousness so Dugu Bo will remain occupied with his granddaughter while Wang Chen harvests the garden 13 19.

Infiltration Through the Tunnel

After locating the spring through controlled soul beasts, Wang Chen waits until Dugu Yan's condition draws Dugu Bo away. He then uses a thousand-year digging soul beast to bypass the poison array through an underground tunnel 14.

Harvest and Absorption

Inside the Eye, Wang Chen collects or consumes multiple immortal herbs based on their suitability. He stores herbs that do not match his immediate needs and absorbs those that strengthen his foundation, meridians, spiritual power, and martial souls 15 16 17.

Investigation of the Dragon King Rumor

After refining the Fiery Apricot Delicate and Octagonal Mysterious Ice Grass, Wang Chen dives to the bottom of the spring expecting possible Ice Dragon King and Fire Dragon King remains. He instead finds only the natural Taiji yin-yang fish formation and concludes the site is formed from heaven-and-earth spiritual veins rather than dragon corpses 18.

Trivia

• Wang Chen considers it unreasonable that Spirit Hall had no record of such a conspicuous treasure land despite Sunset Forest being a major soul beast hunting ground 14.
• Wang Chen explicitly rejects the idea of forcing through Dugu Bo's poison array, calling it unnecessary when he can simply dig underneath 14.
• The spring's bottom contains no Ice Dragon King or Fire Dragon King remains in this novel's version, contradicting the rumor Wang Chen remembers from fanfiction 18.
• Wang Chen sees the herbs at the Eye as suspiciously well-suited to the Shrek Seven Monsters and briefly wonders whether a god arranged them 32.
