Background

Tang Xuan is a transmigrator born into the line of a direct Clear Sky Sect disciple. During the conflict that forced the Clear Sky Sect to seal itself away, his parents died in battle. The surviving group abandoned him in the wilderness, where Chen Xin saved him from a beast and brought him to the Seven Treasure Glazed Tile Sect. His origins were concealed, though Tang Xuan remembered them himself. 1

Chen Xin raised Tang Xuan as his own grandson. Ning Fengzhi and Bone Douluo also participated in his upbringing, but Tang Xuan remained wary of Ning Fengzhi’s calculating nature and believed his treatment might change if Tang Xuan awakened the Clear Sky Hammer. 1 2

At his awakening, Tang Xuan instead manifested the Mysterious Iron Heavy Sword. Its appearance allowed him to remain at the Seven Treasure Glazed Tile Sect without exposing his Clear Sky lineage. 1

Appearance

Tang Xuan’s Martial Soul is a dark, meteorite-iron heavy sword shaped somewhere between a staff and a sword. Its blade is black as ink with a faint red glow, and its weight initially made it impossible for him to hold. 1

• The sword weighed nearly 300 pounds after his first Soul Ring. 4
• His Mysterious Wing External Soul Bone manifests as black wings with golden texture. 28
• At the Mysterious Heavy Sect’s ceremony, he wore a dark robe, a blood-red jade crown, and a nine-colored belt. 347

Personality

Tang Xuan is ambitious and direct about his desire either to inherit his family legacy or “conquer the world.” He later clarifies his broader aim as creating a world he wants to see. 1 74

He values persistent self-improvement, maintaining that there is always someone stronger and that cultivation should never stop. This steady mindset is identified by Yu Tianheng as the source of Tang Xuan’s strength. 16

Tang Xuan is also calculating and boundary-conscious. He refuses to freely disclose his methods to Tang San, leverages Tang San’s curiosity during negotiations, and uses deception and intimidation strategically against Martial Soul Hall. 59 81 238 278

Although often pragmatic and ruthless toward enemies, he is protective of his companions. He risked the Ice and Fire Yin Yang Well’s herbs to cure Dugu Bo and Dugu Yan, strengthened allies with resources and Soul Bones, and eventually recognized that his life and decisions affect those close to him. 33 329 234

Abilities & Skills

Mysterious Iron Heavy Sword

Tang Xuan’s Weapon Martial Soul is an exceptionally heavy sword with overwhelming force and a suppressive presence.

• Initially too heavy for Tang Xuan to lift; he adapted through months of waterfall training. 3
• Its weight increased after Soul Ring absorption, requiring further sealed-Soul-Power training. 4
• By the battle against Qian Renxue, its base weight had reached 80,000 jin. 305
• Its quality was later described as at least the peak of super-tier Martial Souls after tempering by immortal herbs, domains, and Asura Divine Power. 340

Sword Dao

Tang Xuan’s swordsmanship centers on simplification, force, suppression, and eventually selflessness.

• Return to Simplicity — comprehended after finding Chen Xin’s Seven Kill Sword Art overly complicated; reduces technique to fundamental sword movements. 5
• Lifting the Heavy as Light — achieved through extended physical training with an iron rod matching his Martial Soul’s shape and weight. 4 41
• Clumsy Intent Sword Art — a self-created art built on his control of the heavy sword. 41
• Return to Dust — a sword art created by adapting the Great Sumeru Hammer to his own path; combines Clumsy Intent Sword Art with Great Sumeru Hammer principles. 92 172
• Selfless Sword Intent — refined through travel, integration with heaven and earth, and challenging the world’s rules; later evolved beyond its earlier flawed form. 379
• His Sword Dao later surpassed Sword Intent, placing him on an unprecedented path. 228

Collapse Mountain

Tang Xuan’s first Soul Skill, gained from a Mysterious Armor Giant Rhinoceros.

• Sends destructive force through the target rather than visibly damaging only its exterior. 3
• Pulverized the interior of a tree while leaving its exterior apparently intact. 3
• Can generate a dark shockwave that lifts the ground and incapacitates multiple opponents. 11

Mountain River Suppression

A complete form of Tang Xuan’s Sword Momentum, strengthened by the Full Moon Wearing Autumn Dew.

• Uses mental power and sword momentum to impose overwhelming pressure before the sword is drawn. 39
• Emphasizes suppression, restraint, and control rather than Chen Xin’s killing-focused Sword Momentum. 39

Mysterious Wing Soul Bone

An External Soul Bone awakened alongside Tang Xuan’s Thousand Year second ring.

• Manifests as black-and-gold wings capable of flight. 28
• Evolved to a 100,000-year level, granting speed comparable to or greater than a speed-type 100,000-year Soul Beast. 104
• Enabled Tang Xuan and Ning Rongrong to move unnoticed by Chen Xin and return to the Seven Treasure Glazed Tile Sect in under three minutes. 104

Ice Fire Golden Body

A body refinement achieved by consuming Infernal Delicate Apricot and Octagonal Mysterious Ice Grass, then soaking in the Ice and Fire Yin Yang Well.

• Grants immunity to poisons. 33
• Greatly enhanced Tang Xuan’s physical foundation and capacity to endure high-level Soul Rings. 41 92
• His blood could be used as a catalyst to cure Dugu Bo and Dugu Yan’s poisons. 33

Break World

Tang Xuan’s first 100,000-year sixth Soul Skill.

• A single-target attack obtained from the Titan Giant Ape’s Soul Ring. 166
• Produces massive destructive scars across the ground. 167

Qianjun

Tang Xuan’s second 100,000-year sixth Soul Skill.

• Increases the Mysterious Iron Heavy Sword’s weight by up to ten times. 167
• Further amplifies the crushing force central to Tang Xuan’s fighting style. 167

Evil God’s Protection

A powerful defensive Soul Skill.

• Revealed after Tang Xuan’s encounter with the Dark Demon Evil God Tiger. 104
• Considered sufficient to significantly improve his survival prospects before entering Slaughter City. 156

Sky Azure Dragon Soul

Tang Xuan’s evolved eighth Soul Skill, originally named Azure Dragon Puppet.

• Azure Dragon Puppet — used to attack Chrysanthemum Douluo and test its combat applications against Ghost Douluo. 320
• After absorbing the Sky Azure Bull Python’s left leg bone, it evolved into a Sky Azure Divine Dragon and was renamed Sky Azure Dragon Soul. 329
• Requires energy from Tang Xuan during combat and can divide his focus; this contributed to his decision to study Distraction Control. 332

Mental Power

Tang Xuan possesses unusually advanced spiritual strength.

• Reached Soul Douluo-level mental power at level 50. 92
• Later exceeded the Soul Douluo level, though Chen Xin judged it still below the Titled Douluo tier. 161
• Defeated Godwind Academy’s seven-member team without drawing his sword, relying only on Soul Power and mental power. 123
• Developed a “bridge” with heaven and earth that provides warnings and guidance during emergencies. 379

Equipment / Items

• Mysterious Iron Heavy Sword — Tang Xuan’s Martial Soul. 1
• Mysterious Wing External Soul Bone — flight-capable wing bone that later evolved to 100,000-year quality. 28 104

• Sky Azure Bull Python Left Leg Bone — enhanced Tang Xuan to level 84 and evolved Sky Azure Dragon Puppet. 329

• Godly Zhuge Crossbow blueprints — acquired from Tang San in exchange for assisting Xiao Wu. 81

Relationships

• Chen Xin — adoptive grandfather, mentor, and later master; saved Tang Xuan as an infant, raised him at the Seven Treasure Glazed Tile Sect, and guided his Sword Dao. 1 5 92
• Ning Rongrong — childhood companion and close partner; they trained together, travel together, and she consistently worries over his dangerous cultivation choices. 3 104 217 234
• Ning Fengzhi — guardian and adviser within the Seven Treasure Glazed Tile Sect; Tang Xuan initially distrusted his calculations but later accepted his guidance on Distraction Control. 1 332
• Dugu Bo — initially distrustful of Tang Xuan; became grateful after Tang Xuan used the Ice and Fire Yin Yang Well to help cure his and Dugu Yan’s poison. 33
• Dugu Yan — teammate and ally; coined the nickname “Tang Xiao Xuan” and received Tang Xuan’s concern regarding her inherited poison. 28
• Yu Tianheng — rival turned close ally; Tang Xuan defeated him early, later helped his cultivation, and Yu Tianheng ultimately accepted Tang Xuan as his “big brother.” 12 102 229
• Tang San — adversarial acquaintance; Tang Xuan considers Tang San intrusive and repeatedly bargains with him over valuable knowledge and blueprints. 59 81
• Tang Hao — fellow Clear Sky Sect descendant and Tang San’s father; Tang Xuan negotiated mutual assistance with him regarding Xiao Wu and Slaughter City. 156
• Dai Mubai and Zhu Zhuqing — political allies connected to Tang Xuan’s Star Luo plans; they swore to support the Mysterious Heavy Sect after Dai Mubai inherits the throne. 74
