Background

A Martial Soul determines whether an awakened individual can cultivate as a Soul Master. Children without soul power cannot follow the Soul Master path, while innate soul power provides the foundation for later cultivation. Martial Souls generally manifest during a formal awakening ceremony. 1 2

Beast Martial Souls can be used through Martial Soul Possession, channeling a beast's qualities into the user's body. Tool Martial Souls follow different development paths and are taught alongside Beast Martial Souls in foundational academy theory. 2 23

Yu Yan's Ice and Fire Twin Fish was initially mistaken for Twin Martial Souls because it manifests as two separate fish. Yu Yan clarified that the Ice Fish and Fire Fish are parts of one Martial Soul. 1 30

Companion Martial Souls

A Companion Martial Soul is described as “two souls in one”: stronger than an ordinary single Martial Soul but weaker than true Twin Martial Souls. Its paired components possess innate compatibility, allowing the user to perform Martial Soul Fusion Skills alone. 1

For the Ice and Fire Twin Fish, each absorbed Soul Ring produces:

• One primarily ice-attributed soul skill.
• One primarily fire-attributed soul skill.
• One solo Martial Soul Fusion Skill created by balancing or combining the two attributes. 70 149

Appearance

The Ice and Fire Twin Fish manifests as two energy-formed beast spirits circling Yu Yan or appearing from his hand. The Ice Fish is crystal-clear and releases cold air or ice crystals, while the Fire Fish is fiery red and surrounded by heat and flame. 2 149

• Ice Fish — associated with frost, cold energy, binding, protection, and battlefield control.
• Fire Fish — associated with high temperatures, explosions, burning, and burst damage.
• Paired form — the two fish chase one another head-to-tail, forming a balanced Yin-Yang-like pattern. 149
• Possession form — the Twin Fish can attach to Yu Yan's arms and substantially increase his physical strength. 2

Abilities & Skills

Martial Soul Possession

As a Beast Martial Soul, the Ice and Fire Twin Fish can attach to Yu Yan's body and reinforce him physically.

• Greatly increases Yu Yan's strength; his first test punch tore through a sandbag. 2
• Allows the Fire Fish to ignite targets and the Ice Fish to extinguish fire with cold air. 2
• The two halves can be manipulated independently only with difficulty; an early attempt to manifest one fish while retracting the other exhausted Yu Yan's soul power. 3

Dual-Attribute Control

The Twin Fish simultaneously wield opposing ice and fire attributes.

• Ice techniques emphasize defense, freezing, slowing, binding, and sustained interference.
• Fire techniques emphasize explosive force, burning, secondary splash damage, and burst offense. 76 97
• Simultaneous use requires careful mental control and balance; improper coordination risks backlash and severe soul-power expenditure. 149 247

First Soul Ring Techniques

The first yellow Soul Ring came from an Ice and Fire Sub-Dragon Lizard. 28 29

• Frost Scale Armor / Ice Scale Armor — creates frost armor for physical defense and cold resistance; close enemies may suffer frostbite or slowing. Individual armor pieces can also be formed separately. 29 72 300
• Scorching Breath — releases a flame from Yu Yan's mouth or the Fire Fish's mouth to inflict burn damage. 29 300
• Ice and Fire Vortex — creates a vortex that pulls in enemies, continuously deals ice-and-fire damage, and inflicts rotational cutting control damage. It may be thrown outward or used around Yu Yan as offense and defense. 48

Second Soul Ring Techniques

The second ring was absorbed from the Frost Ash Remnant Dragon. 73 74

• Mystic Ice Chains — controllable chains that bind, strike, freeze, and slow soul-power circulation through invading cold energy. Yu Yan can control four chains at his then-current level. 76 79
• Blazing Dragon Roar — a high-explosive fire attack that detonates on contact and can leave lingering flames for secondary splash and burn damage. 76 300
• Ice Fire Profound Mystery: Ice Flame Explosion Chain — ice-and-fire chains produce violent energy shocks and massive explosions when their opposing energies collide. 77 300

Third Soul Ring Fusion Skill

Sun and Moon Shine Together: Eternal Tribulation is an auxiliary Martial Soul Fusion Skill centered on Sun and Moon Resonance. 131

• Combines Moon Eclipse and Sun Glory to grant a chosen target the Twin Blessing.
• Can block one full-power attack from a Soul Master no more than twenty levels above Yu Yan.
• Temporarily increases all attributes by 200%.
• Can convert stored negative effects, such as poison or curses, into beneficial effects such as recovery or buffs. 131 300

Avatar of the Martial Soul

Yu Yan's seventh Soul Ring grants a two-form Avatar of the Martial Soul rather than a single unified form. 212

• Ice Dragon Avatar — amplifies ice-attribute soul skills to 150% of their original power and creates surrounding frost that affects nearby targets. 214
• Fire Dragon Avatar — amplifies fire-attribute soul skills to 200% of their original power. 214
• Yu Yan can transform into either avatar or manifest both simultaneously. 212
• Combined with his rapid skill release, the Avatar allows extensive chaining of ice, fire, and fusion techniques. 214

Eighth Soul Ring Techniques

The eighth Soul Ring grants two Ice Dragon skills, two Fire Dragon skills, and one Martial Soul Fusion Skill. 271

• Snow Kingdom Grotto-Heaven — Ice Dragon skill. 271
• Myriad Flower Jade Mirror — creates a mirror combining martial soul, soul power, and mental power; it can identify illusions and clones, reveal the true body, and fire condensed mirror-light attacks. 271
• Burning Firmament Fire Furnace — Fire Dragon skill. 271
• Extreme Fire Sword — Fire Dragon skill. 271
• Boundless Calamity: Ice-Fire Path Extinction — eighth-ring Martial Soul Fusion Skill. 271

Documented Martial Soul Fusion Skills

Fusion Skill	Associated Ring	Function
Ice and Fire Vortex	First	Suction, continuous ice-and-fire damage, rotational cutting, defense, and control; notably drains soul power quickly. 48

Sun and Moon Shine Together: Eternal Tribulation	Third	Auxiliary field and blessing technique based on Sun and Moon Resonance. 131

Boundless Calamity: Ice-Fire Path Extinction	Eighth	Eighth-ring fusion technique obtained from the Douluo Planet Consciousness. 271

Limitations

• Maintaining both Fish simultaneously consumes considerably more soul power than normal Martial Soul use. 3
• Martial Soul Fusion Skills are exceptionally demanding; Ice and Fire Vortex exhausted Yu Yan completely after thirty-two seconds at level 12. 48
• The martial soul's full potential depends on precise control of conflicting ice and fire energies, strong mental power, physical endurance, and sufficient soul-power reserves. 149 247
• Yu Yan later pursued liquefied and solidified soul power specifically to make repeated fusion-skill use viable in extended combat. 146 180 268

Story Role / Major Arcs

• Awakening in Fish Village — Yu Yan awakens the Ice and Fire Twin Fish with innate level 7.5 soul power. Gong Fenghua initially mistakes it for Twin Martial Souls and attempts to recruit Yu Yan into Martial Soul Hall. 1
• Early cultivation — Yu Yan develops Martial Soul Possession, begins meditation, and experiments with independently controlling the Ice and Fire Fish. 2 3
• First and second rings — the martial soul develops its first defensive, offensive, binding, explosive, and fusion techniques through the Ice and Fire Sub-Dragon Lizard and Frost Ash Remnant Dragon rings. 28 29 74 76
• Faction attention — the unusual Companion Martial Soul attracts recruitment attempts from major factions and interest from nobles seeking to preserve its bloodline through marriage. 48 76
• Dragon evolution — repeated ring absorption, Dragon King blood, scale soul bones, and long-term cultivation transform the Twin Fish into the Ice and Fire Twin Dragons and ultimately the Ice and Fire Dragon King. 212 256 335

Trivia

• The Ice and Fire Twin Fish is officially recorded as a mutated Martial Soul on Yu Yan's Martial Soul Awakening Certificate. 184
• Martial Soul Hall personnel repeatedly mistake the Twin Fish for Twin Martial Souls because its two components manifest separately. 1 28 30
• Yu Yan can use the Fire Fish's stable high-temperature flames for practical work, including blacksmithing and refining medicine. 39 132
