Background

Cao Xin is the son of Cao Dezhi and Zang Xin, inheriting both fathers’ unique mutated Martial Souls: the Sentimental Sword and the Ruthless Sword. Though their attributes are opposed, their Soul Power circulates through him in a harmonious cycle rather than clashing. 2

Immediately after his Martial Soul awakening, the Concept Roulette Draw System binds to him and presents five conceptual abilities. Cao Xin rejects Undying Body and Cannot Be Defined, choosing Self, Set Facts Aside, and Alchemy Furnace because he values human relationships and personal identity over invulnerability or incomprehensibility. 3 4

His fathers use Tang Sect resources to secure high-quality Soul Rings and personally oversee his early cultivation. Their protection remains absolute: Zang Xin tells Cao Xin that, as long as he and Cao Dezhi live, even if the sky falls, they will “patch it back up” for him. 5 20

Appearance

Cao Xin is a handsome young boy with a composed, refined temperament that makes him stand apart from those around him. 58

• Sentimental Sword — Manifested in his left hand; a crystalline, nearly transparent longsword with a faint rainbow glow and a gentle, agile aura. 2
• Ruthless Sword — Manifested in his right hand; an ancient bronze-green longsword marked by restrained patterns and an austere, unyielding presence. 2
• Right eye — Houses a violet-gold Evil Eye Tyrant External Soul Bone; a blood-red gleam appears when its power is active. 13

Personality

Cao Xin is calm and analytical when confronting extraordinary circumstances. He carefully evaluates power according to long-term potential rather than immediate utility, which is why he selected reality-altering conceptual abilities over functional immortality. 3 4

He values humanity, emotions, and bonds despite his ruthlessness toward enemies. He rejected Cannot Be Defined because it would isolate him from his fathers, companions, and ordinary life. 4

In battle, Cao Xin is confident, disciplined, and highly dangerous. He enjoys seeking stronger opponents, maintains an intensive sparring routine, and treats lethal threats with detached efficiency. 15 26 27 His later breakthrough comes from recognizing that pure pursuit of strength had left him emotionally detached and unable to choose between the Ruthless and Passionate Paths. 45

Abilities & Skills

Twin Martial Souls

Cao Xin possesses two top-tier, mutually complementary sword Martial Souls inherited from Cao Dezhi and Zang Xin. 2 6

• Sentimental Sword — Specializes in emotional influence, temporal reversal, counterattacks, and spiritual techniques. 5 7 32
• Ruthless Sword — Channels seasonal Sword Intent, destructive force, silence, decay, life, death, and natural law. 6 7 32
• His twin Martial Souls allow him to absorb thousand-year Soul Rings as his first rings without bodily collapse. 6

Conceptual Abilities

Self

Self causes the patterns and laws of the world to favor Cao Xin when his will is firm enough. Its effects are gradual rather than instant, but it can reshape his surroundings on a massive scale. 3

• Turned a book into a ceramic cup when combined with Set Facts Aside. 4
• Created a blizzard inside the Spirit Ascension Platform to cripple the Evil Eye Tyrant’s spiritual perception. 12
• Converts prepared terrain into an extension of his will, allowing him to control wind, darkness, snow, light, and environmental awareness. 26 27
• Prevents opponents from freely mobilizing heaven-and-earth energy within his controlled space. 84 85
• Requires belief and time for reality’s laws to gradually align with his intent. 3

• Removes the causal condition that would allow a spiritual attack to affect him. 13
• Allows him to disregard the spiritual-realm requirement for fusing the Evil Eye Tyrant External Soul Bone. 11
• Bypasses Cai Yue’er’s ability to defend against Mental Shockwave. 32

• Refines defeated enemies and removes all physical evidence, including corpses, blood aura, and resentment. 28 38 39

• Combines emotional influence with temporal reversal. 5

• Nullified a Seven-Ring Soul Sage’s lightning attack. 19

• Shattered Cai Yue’er’s defensive crescent-moon barrier. 32
• Forms part of his dual-sword sequence against superior opponents. 32

Four Seasons Sword Intent

Cao Xin’s Ruthless Sword Soul Skills are artistic-conception states rather than ordinary fixed techniques. His blade can embody different seasonal forces based on his comprehension. 6

• Mid-Autumn — Represents harvest, prosperity, fulfillment, and abundant life. 6
• Late Autumn — Represents desolation, decay, death, and the weakening of an enemy’s fighting spirit, Soul Power, and vitality. 6
• Winter — Adds Slaughter and Silence to his Sword Intent. 7
• Deep Winter — The silent, lethal extreme of winter; used to pierce and instantly kill the Evil Eye Tyrant. 12
• Late Summer — Produces intense heat capable of threatening a Seven-Ring Soul Sage. 19
• Four Seasons Cycle — Compresses summer, autumn, winter, and forcibly generated spring into a complete cycle; grants Cao Xin contact with the Time Law. 32
• Wither and Flourish of Heaven and Earth — A Four Seasons strike embodying life, death, decay, and renewal; destroyed the Asura God’s remnant thought and blood-red giant sword. 103

Mental Shockwave

An area-of-effect spiritual attack granted by the Evil Eye Tyrant right-eye External Soul Bone. 13

• Can be released repeatedly to suppress groups of enemies. 13

• Empowered by Divine Origin Realm spiritual strength, it incapacitated the pilots of hundreds of mechas at once. 81

• Sword Flash Across Nineteen Continents — Fills an area with snow and releases a single enormous sword radiance capable of killing nearly one hundred Evil Soul Masters. 38
• Myriad Things Reincarnation — A Four Seasons-based technique used alongside an incomplete Life-and-Death Power against Na Nali. 39

Ice and Fire Dragon King Souls
