Background / History

Su Yuntian was an ordinary high-school student from Earth who transmigrated into the body of an eleven-year-old orphan on the Douluo Continent. Before his awakening, he was sickly, had no Soul Power, and appeared unable to awaken a Martial Soul; he depended entirely on his older brother, Su Yuntao 1.

His consciousness was drawn into a Soul Power-testing crystal ball, where he encountered darkness, curses, and Gilgamesh. He subsequently inherited Gilgamesh's power and awakened Twin Martial Souls: the Key of Royal Law and a rare Four-Winged Angel 2 3. Su Yuntao immediately warned him to conceal the Angel Martial Soul, fearing the attention it would attract 3.

The awakening drew the interest of Xue Qinghe, who sent assassins after the brothers. During their escape, Su Yuntian secretly used the Four-Winged Angel to suppress Old Blade's Soul Power and, with Su Yuntao's assistance, killed him despite their immense difference in level 7 8. He later collapsed from exhaustion and was separated from his brother after Qian Renxue arranged for Su Yuntao to leave him in her care for at least three years 9.

Under the identity of Xue Qinghe, Qian Renxue brought him to Heaven Dou City and placed him in the Crown Prince's Mansion. Su Yuntian accepted a servant-like position in the entourage both for protection and to find Su Yuntao 10 11. He was later made a baron, knight, and the Crown Prince's companion reader after Xue Qinghe became Crown Prince 20.

Appearance

After awakening his Martial Souls, Su Yuntian's appearance changed substantially from the black-haired, black-eyed child he had been before.

  • Short pale-gold hair.
  • Ruby-red eyes described as unusually captivating 3 21.
  • Developed from a thin, sickly child into a muscular, increasingly tall teenager during his time in Heaven Dou City 18.
  • Has a handsome face whose once-soft features became more masculine with age 21.
  • His Four-Winged Angel manifests as two pairs of wings: one white-feathered pair and one black pair 2.

Personality

Su Yuntian is resilient, ambitious, and acutely aware that power is necessary to survive in the Douluo Continent. His late awakening leaves him anxious about falling behind stronger young Soul Masters, driving him to take calculated risks such as absorbing Soul Rings above normal age limits 13 33 36.

He is tactically minded in battle, preferring distance, positioning, and overwhelming weapon barrages over straightforward close combat 22. He can also be arrogant, playful, and provocative—particularly toward Ning Rongrong—but shows genuine loyalty toward Su Yuntao, Da Xue, and those who recognize or support him 17 28 36.

His stated ideal is to live freely without compromising his principles, while becoming strong enough to protect himself and the people he loves 26.

Abilities & Skills

Twin Martial Souls

Su Yuntian possesses two Martial Souls, though he publicly presents only the Key of Royal Law.

  • Key of Royal Law — A golden key connected to Gilgamesh's conceptual treasury, the Gate of Babylon 3.
  • Four-Winged Angel — A hidden Angel Martial Soul whose unusual nature alarms even Qian Renxue 2 8.
  • He agreed to keep the Angel Martial Soul secret because of its potential connection to Spirit Hall's Angel lineage 3.

Four-Winged Angel: Death Sentence Angel

The Angel Martial Soul possesses an innate suppression effect rather than a conventional Soul Skill.

  • Every attack can dissolve and suppress an opponent's Soul Power 8.
  • Its attacks carry the concept of “death,” causing Old Blade to fear it despite his far higher Soul Power 8.
  • Su Yuntian initially did not understand this ability and mistakenly named an improvised Soul Power attack “Crimson Annihilation” to intimidate his enemy 8.
  • Using the Angel Martial Soul rapidly exhausts his limited Soul Power; after fighting Old Blade, he collapsed unconscious 9.

First Soul Skill: Gate of Babylon

Obtained from the 600-year Purple Fir Soul Ring, this ability opens gateways to Gilgamesh's treasury 13.

  • Retrieves low-level items such as swords, cleavers, food, and clothing with minimal Soul Power 13.
  • Functions as a storage space and can be used similarly to a Soul Tool 15.
  • Fires weapons through Aether Gates for long-range bombardment 21 22.
  • By Level 23, Su Yuntian could open up to sixteen gates at once 35.
  • High-level treasures remain inaccessible because his Soul Power is insufficient 13.
  • He developed a copying function, but it consumes too much Soul Power to be practical 18.

Flash

A derivative application of Gate of Babylon that allows instantaneous self-teleportation.

  • Used to reposition, evade attacks, and strike from behind 14 22.
  • Can teleport only Su Yuntian himself; he has been unable to transport other people 18.
  • Cannot be used indefinitely and consumes Soul Power 30.

Second Soul Skill: Beautiful Youth of Red Face

Obtained from the 1,700-year Snow Fox Soul Ring, this is a Charm-type ability 34.

  • Charms a single target regardless of gender for approximately five seconds 34 35.
  • Can produce exaggerated results against targets far weaker than Su Yuntian, such as the non-Soul Master Da Xue 35.
  • Can be activated through his ruby-red eyes 35 36.
  • Its initial uncontrolled activation charmed Lin Mengzhui, leading her to slap him after she recovered 34.

Equipment / Weapons / Items

  • Short sword — Carried for self-defense during the assassins' pursuit 7.
  • Gate of Babylon treasures — Summoned swords, spears, blades, halberds, food, clothing, and other stored items 13 21.
  • Golden chain — Retrieved from the Gate of Babylon after gaining his second Soul Ring 35.
  • Mysterious Spirit Ganoderma — Given by Ning Fengya as a token of friendship and stored in the Gate of Babylon 28.

Relationships

  • Su Yuntao — Older brother and former caretaker. Su Yuntian's strongest familial bond; they were separated after Qian Renxue took Su Yuntian away for cultivation, and Su Yuntao later became missing 1 9 19.
  • Xue Qinghe / Qian Renxue — Protector, patron, and politically dangerous mentor. She guides his cultivation, provides resources, and keeps him at the Crown Prince's Mansion; Su Yuntian gradually comes to understand her loneliness and hidden identity 12 20 26 36.
  • Da XueXue Qinghe's maid and the first person Su Yuntian saw after awakening in Nuoding City. He treats her as an older sister and promises to protect her after learning she knows Xue Qinghe's secret 10 35 36.
  • Ning Fengya — Close friend and sparring partner. Su Yuntian encourages him to recognize the potential of his mutated Black Tower Martial Soul, and Ning Fengya declares him his best friend for life 24 28.
  • Ning Rongrong — Rival with a longstanding grudge after Su Yuntian humiliated her in two separate fights. Despite his taunting, he later considers making amends to avoid provoking Sword Douluo Chen Xin further 17 23.
  • Lu Renjia — Imperial City Guard captain who escorts Su Yuntian on his second Soul Ring hunt and admires his willingness to absorb a 1,700-year Soul Ring 30 33 34.
  • Lin Mengzhui — Hired control-type Soul Master who assisted in hunting the Snow Fox. She was unintentionally charmed by Su Yuntian's new second Soul Skill 32 34.
  • Gilgamesh — The Hero King whose inheritance granted Su Yuntian the Key of Royal Law and access to the Gate of Babylon 2 3.
